What Facebook Owes to Journalism - The New York Times - 0 views

  • declared that “a strong news industry is also critical to building an informed community.”
  • Unfortunately, his memo ignored two major points — the role that Facebook and other technology platforms are playing in inadvertently damaging local news media, and the one way they could actually save journalism: with a massive philanthropic commitment.
  • As advertising spending shifted from print, TV and radio to the internet, the money didn’t mostly go to digital news organizations. Increasingly, it goes to Facebook and Google.

  • But just because the result is unintentional doesn’t mean it is fantasy: Newsrooms have been decimated, with basic accountability reporting slashed as a result.
  • I’m not saying that the good stuff — the mobile revolution, blocking intrusive ads, better marketing options for small businesses — doesn’t outweigh the bad. And local news organizations absolutely contributed to the problem with their sluggish and often uncreative reaction to the digital revolution.
  •  
    This article discuss the impact of internet on local news organizations. I agree with the author that the internet do get a lot of ad money and make local news organizations have less funding. Although there are donations, it is still very little compare to what local news organizations used to have. This might be part of the reason why local news organizations don't do well on giving great informations.But I think the time is moving forward, Facebook and google should take some of the responsibility as they get more funding and resources. This article is very persuasive as it has many data and evidence in support. I really like that the author acknowledge the counterargument in his article to make it more reliable. --Sissi (2/22/2017)

3-D-printed organs are on the way - Nov. 4, 2014 - 0 views

  • Add one more to the growing list of 3-D-printed products: human organs.
  • Within the next few years, Renard says 3-D-printed tissues could also be used in patient treatment, to replace small parts or organs or encourage cell regeneration.
  • Once the cells have been printed in the right arrangement, they begin to signal to one another, fuse and organize themselves into a collective system.

New Prospects for Growing Human Replacement Organs in Animals - The New York Times - 0 views

  • For the first time, biologists have succeeded in growing human stem cells in pig embryos, shifting from science fiction to the realm of the possible the idea of developing human organs in animals for later transplant.
  • Since the organ would be made of a patient’s own cells, there would be little risk of immune rejection.
  • They would be generated by implanting human stem cells into an early pig embryo, resulting in an animal composed of mixed pig and human cells.
  • ...5 more annotations...
  • The two reports together establish the feasibility of trying to grow replacement human organs in animals, though such a goal is still far off.
  • Creating chimeras, especially those with human cells, may prove controversial, given the possibility that test animals could be humanized in undesirable ways. One would be if human cells should be incorporated into a pig’s brain, endowing it with human qualities. Almost no one wants a talking pig.
  • The ban is still in place, and it’s unclear whether the Trump administration would continue to consider lifting the moratorium or whether new objections would be raised to using public funds for this line of research.
  • But no one knows exactly what sequence of chemicals is required for the generation of each different tissue or organ. This may be why glassware experiments with stem cells have not yet lived up to their full promise.
  • Concern about human cells’ incorporation into a lower animal’s brain is not without basis. Dr. Steven Goldman of the University of Rochester Medical Center found in 2013 that mice injected with a special type of human brain cell had enhanced learning abilities.
  •  
    The ethics in biology is always a controversial issue in the research. In biology, we want to get as close to the truth as we possibly can, but that sometimes means that we have to research on things that are considered to be inhumane. This article talks about a new possibility that we can grow human stem cells in animals. That would lead to a potential problem of animals gaining intelligence. If animals start to have human properties, how would we treat them? Will they be a threat to our identity? And also, through the experiment described in the article, we can see that the scientific method in biology is dealing with probabilism and population. It is always gathering data. They are always ready for exceptions. --Sissi (1/28/2017)

Facebook will now ask users to rank news organizations they trust - The Washington Post - 0 views

  • Zuckerberg wrote Facebook is not “comfortable” deciding which news sources are the most trustworthy in a “world with so much division."
  • "We decided that having the community determine which sources are broadly trusted would be most objective," he wrote.
  • The new trust rankings will emerge from surveys the company is conducting. "Broadly trusted" outlets that are affirmed by a significant cross-section of users may see a boost in readership, while less known organizations or start-ups receiving poor ratings could see their web traffic decline
  • ...14 more annotations...
  • The company's changes include an effort to boost the content of local news outlets, which have suffered sizable subscription and readership declines
  • The changes follow another major News Feed redesign, announced last week, in which Facebook said users would begin to see less content from news organizations and brands in favor of "meaningful" posts from friends and family.
  • Currently, 5 percent of Facebook posts are generated by news organizations; that number is expected to drop to 4 percent after the redesign, Zuckerberg said.
  • On Friday, Google announced it would cancel a two-month-old experiment, called Knowledge Panel, that informed its users that a news article had been disputed by independent fact-checking organizations. Conservatives had complained the feature unfairly targeted a right-leaning outlet.
  • More than two-thirds of Americans now get some of their news from social media, according to Pew Research Center.
  • That shift has empowered Facebook and Google, putting them in an uncomfortable position of deciding what news they should distribute to their global audiences. But it also has led to questions about whether these corporations should be considered media companie
  • "Just by putting things out to a vote in terms of what the community would find trustworthy undermines the role for any serious institutionalized process to determine what’s quality and what’s not,” he said.
  • rther criticism that the social network had become vulnerable to bad actors seeking to spread disinformation.
  • Jay Rosen, a journalism professor at New York University, said that Facebook learned the wrong lesson from Trending Topics, which was to try to avoid politics at all costs
  • “One of the things that can happen if you are determined to avoid politics at all costs is you are driven to illusory solutions,” he said. “I don’t think there is any alternative to using your judgement. But Facebook is convinced that there is. This idea that they can avoid judgement is part of their problem.”
  • Facebook revealed few details about how it is conducting its trust surveys,
  • "The hard question we've struggled with is how to decide what news sources are broadly trusted," Zuckerberg wrote. "We could try to make that decision ourselves, but that's not something we're comfortable with. We considered asking outside experts, which would take the decision out of our hands but would likely not solve the objectivity problem. Or we could ask you -- the community -- and have your feedback determine the ranking."
  • Some experts wondered whether Facebook's latest effort could be gamed.
  • "This seems like a positive step toward improving the news environment on Facebook," Diresta said. "That said, the potential downside is that the survey approach unfairly penalizes emerging publications."

Marie Kondo and the Ruthless War on Stuff - The New York Times - 1 views

  • the method outlined in Kondo’s book. It includes something called a “once-in-a-lifetime tidying marathon,” which means piling five categories of material possessions — clothing, books, papers, miscellaneous items and sentimental items, including photos, in that order — one at a time, surveying how much of each you have, seeing that it’s way too much and then holding each item to see if it sparks joy in your body. The ones that spark joy get to stay. The ones that don’t get a heartfelt and generous goodbye, via actual verbal communication, and are then sent on their way to their next life.
  • She is often mistaken for someone who thinks you shouldn’t own anything, but that’s wrong. Rather, she thinks you can own as much or as little as you like, as long as every possession brings you true joy.
  • By the time her book arrived, America had entered a time of peak stuff, when we had accumulated a mountain of disposable goods — from Costco toilet paper to Isaac Mizrahi swimwear by Target — but hadn’t (and still haven’t) learned how to dispose of them. We were caught between an older generation that bought a princess phone in 1970 for $25 that was still working and a generation that bought $600 iPhones, knowing they would have to replace them within two years. We had the princess phone and the iPhone, and we couldn’t dispose of either. We were burdened by our stuff; we were drowning in it.

  • A woman named Diana, who wore star-and-flower earrings, said that before she tidied, her life was out of control. Her job had been recently eliminated when she found the book. “It’s a powerful message for women that you should be surrounded by things that make you happy,”
  • “I found the opposite of happiness is not sadness,” Diana told us. “It’s chaos.”
  • Another woman said she KonMaried a bad boyfriend. Having tidied everything in her home and finding she still distinctly lacked happiness, she held her boyfriend in her hands, realized he no longer sparked joy and got rid of him.
  • She realized that the work she was doing as a tidying consultant was far more psychological than it was practical. Tidying wasn’t just a function of your physical space; it was a function of your soul.
  • . She wants you to override the instinct to keep a certain thing because an HGTV show or a home-design magazine or a Pinterest page said it would brighten up your room or make your life better. She wants you to possess your possessions on your own terms, not theirs
  • she would say to him what she said to me, that yes, America is a little different from Japan, but ultimately it’s all the same. We’re all the same in that we’re enticed into the false illusion of happiness through material purchase.
  • She leaves room for something that people don’t often give her credit for: that the KonMari method might not be your speed. “I think it’s good to have different types of organizing methods,” she continued, “because my method might not spark joy with some people, but his method might.
  • Conference was different from the KonMari events that I attended. Whereas Kondo does not believe that you need to buy anything in order to organize and that storage systems provide only the illusion of tidiness, the women of Conference traded recon on timesaving apps, label makers, the best kind of Sharpie, the best tool they own (“supersticky notes,” “drawer dividers”)
  • They don’t like that you have to get rid of all of your papers, which is actually a misnomer: Kondo just says you should limit them because they’re incapable of sparking joy, and you should confine them to three folders: needs immediate attention, must be kept for now, must be kept forever.
  • each organizer I spoke with said that she had the same fundamental plan that Kondo did, that the client should purge (they cry “purge” for what Kondo gently calls “discarding”) what is no longer needed or wanted; somehow the extra step of thanking the object or folding it a little differently enrages them. This rage hides behind the notion that things are different here in America, that our lives are more complicated and our stuff is more burdensome and our decisions are harder to make.
  • Ultimately, the women of NAPO said that Kondo’s methods were too draconian and that the clients they knew couldn’t live in Kondo’s world. They had jobs and children, and they needed baby steps and hand-holding and maintenance plans. They needed someone to do for them what they couldn’t naturally do for themselves.
  • the most potent difference between Kondo and the NAPO women is that the NAPO women seek to make a client’s life good by organizing their stuff; Kondo, on the other hand, leads with her spiritual mission, to change their lives through magic.
  • She went to work in finance, but she found the work empty and meaningless. She would come home and find herself overwhelmed by her stuff. So she began searching for “minimalism” on the internet almost constantly, happening on Pinterest pages of beautiful, empty bathrooms and kitchens, and she began to imagine that it was her stuff that was weighing her down. She read philosophy blogs about materialism and the accumulation of objects. “They just all talked about feeling lighter,”
  • “I never knew how to get here from there,” she said. Ning looked around her apartment, which is spare. She loves it here now, but that seemed impossible just a couple of years ago.
  • She found Kondo’s book, and she felt better immediately, just having read it. She began tidying, and immediately she lost three pounds. She had been trying to lose weight forever, and then suddenly, without effort, three pounds, just gone.
  • when it comes to stuff, we are all the same. Once we’ve divided all the drawers and eliminated that which does not bring us joy and categorized ourselves within an inch of our lives, we’ll find that the person lying beneath all the stuff was still just plain old us. We are all a mess, even when we’re done tidying.

Scholar Behind Viral 'Oligarchy' Study Tells You What It Means - 0 views

  • Let's talk about the study. If you had 30 seconds to sum up the main conclusion of your study for the average person, how would you do so? I'd say that contrary to what decades of political science research might lead you to believe, ordinary citizens have virtually no influence over what their government does in the United States. And economic elites and interest groups, especially those representing business, have a substantial degree of influence. Government policy-making over the last few decades reflects the preferences of those groups -- of economic elites and of organized interests.
  • People mean different things by the term oligarchy. One reason why I shy away from it is it brings to mind this image of a very small number of very wealthy people who are pulling strings behind the scenes to determine what government does. And I think it's more complicated than that. It's not only Sheldon Adelson or the Koch brothers or Bill Gates or George Soros who are shaping government policy-making. So that's my concern with what at least many people would understand oligarchy to mean.
  • What "Economic Elite Domination" and "Biased Pluralism" mean is that rather than average citizens of moderate means having an important role in determining policy, ability to shape outcomes is restricted to people at the top of the income distribution and to organized groups that represent primarily -- although not exclusively -- business.
  • ...9 more annotations...
  • When did things start to become this way? It's possible that in earlier eras, that we don't have data for, that things were better. But in the time period that we do have data for, there's certainly no such evidence. Over time responsiveness to elites has grown.
  • Talk about some examples of policy preferences that the majority holds that the government is not responsive to. Financial reform -- the deregulatory agenda has been pursued, somewhat more fervently among Republicans but certainly by Democrats as well in recent decades. Higher minimum wage. More support for the unemployed. More support for education spending. We'd see, perhaps ironically, less liberal policies in some domains like religious or moral issues. Affluent people tend to be more socially liberal on things like abortion or gay rights.
  • Given your findings, what do you make of the great sense of persecution that people at the top appear to feel in recent years? Is there a phenomenon you came by that speaks to this, and does that perpetuate the cycle of policy moving in their direction? It's certainly not something our study or data has addressed. But it's part of an effort to defend, in the face of growing inequality, their advantages and wealth.
  • what kind of data do you use to test this theory and how confident are you in the conclusions? What we did was to collect survey questions that asked whether respondents would favor or oppose some particular change in federal government policy. These were questions asked across the decades from 1981 to 2002. And so from each of those questions we know what citizens of average income level prefer and we know what people at the top of the income distribution say they want. For each of the 2,000 possible policy changes we determined whether in fact they've been adopted or not. I had a large number of research assistants who spent years putting that data together.
  • What are the three or four most crucial factors that have made the United States this way? Very good question. I'd say two crucial factors. One central factor is the role of money in our political system, and the overwhelming role that affluent individuals that affluent individuals and organized interests play, in campaign finance and in lobbying. And the second thing is the lack of mass organizations that represent and facilitate the voice of ordinary citizens. Part of that would be the decline of unions in the country which has been quite dramatic over the last 30 or 40 years. And part of it is the lack of a socialist or a worker's party.
  • Your study calls to mind something that Dennis Kucinich, the former congressman, said years ago during the recession. He essentially said the class war is over and the working class lost. Was he right? I mean, for now, it certainly seems like it. The middle class has not done well over the last three and a half decades, and certainly has not done well during the Great Recession. The political system responded to the crisis in a way that led to a pretty nice recovery for economic elites and corporations.
  • sometimes non-rich people favor an agenda that supports the rich. For instance, middle class tea partiers want low taxes on the highest earners, just as Steve Forbes does. Isn't that still democracy at work, albeit in an arguably perverse way? Yes, absolutely. I think people are entitled to preferences that conflict with their immediate interests -- narrowly conceived interests. That may be an example of that. Opposition to the estate tax among low-income individuals is another. But what we see in this study is that's not what this is happening. We don't look at whether preferences expressed by these different groups are consistent or inconsistent with their interests, narrowly conceived. We just look at whether they're responded to by government policy-makers, and we find that in the case of ordinary Americans, they're not.
  • A new political science study that's gone viral finds that majority-rule democracy exists only in theory in the United States -- not so much in practice. The government caters to the affluent few and organized interest groups, the researchers find, while the average citizen's influence on policy is "near zero."
  • TPM spoke to Gilens about the study, its main findings and its lessons.

Scientists identify vast underground ecosystem containing billions of micro-organisms |... - 0 views

  • Despite extreme heat, no light, minuscule nutrition and intense pressure, scientists estimate this subterranean biosphere is teeming with between 15bn and 23bn tonnes of micro-organisms, hundreds of times the combined weight of every human on the planet.
  • Researchers at the Deep Carbon Observatory say the diversity of underworld species bears comparison to the Amazon or the Galápagos Islands, but unlike those places the environment is still largely pristine because people have yet to probe most of the subsurface.
  • “It’s like finding a whole new reservoir of life on Earth,” said Karen Lloyd, an associate professor at the University of Tennessee in Knoxville. “We are discovering new types of life all the time. So much of life is within the Earth rather than on top of it.
  • ...9 more annotations...
  • The team combines 1,200 scientists from 52 countries in disciplines ranging from geology and microbiology to chemistry and physics.
  • The results suggest 70% of Earth’s bacteria and archaea exist in the subsurface
  • “The strangest thing for me is that some organisms can exist for millennia. They are metabolically active but in stasis, with less energy than we thought possible of supporting life.”
  • Some microorganisms have been alive for thousands of years, barely moving except with shifts in the tectonic plates, earthquakes or eruption
  • these organisms are part of slow, persistent cycles on geological timescales.”
  • Underworld biospheres vary depending on geology and geography. Their combined size is estimated to be more than 2bn cubic kilometres, but this could be expanded further in the future
  • The researchers said their discoveries were made possible by two technical advances: drills that can penetrate far deeper below the Earth’s crust, and improvements in microscopes that allow life to be detected at increasingly minute levels.
  • The scientists have been trying to find a lower limit beyond which life cannot exist, but the deeper they dig the more life they find. There is a temperature maximum – currently 122C – but the researchers believe this record will be broken if they keep exploring and developing more sophisticated instruments.
  • Robert Hazen, a mineralogist at the Carnegie Institution for Science, said: “We must ask ourselves: if life on Earth can be this different from what experience has led us to expect, then what strangeness might await as we probe for life on other worlds?”

The Disease Detective - The New York Times - 1 views

  • What’s startling is how many mystery infections still exist today.
  • More than a third of acute respiratory illnesses are idiopathic; the same is true for up to 40 percent of gastrointestinal disorders and more than half the cases of encephalitis (swelling of the brain).
  • Up to 20 percent of cancers and a substantial portion of autoimmune diseases, including multiple sclerosis and rheumatoid arthritis, are thought to have viral triggers, but a vast majority of those have yet to be identified.
  • ...34 more annotations...
  • Globally, the numbers can be even worse, and the stakes often higher. “Say a person comes into the hospital in Sierra Leone with a fever and flulike symptoms,” DeRisi says. “After a few days, or a week, they die. What caused that illness? Most of the time, we never find out. Because if the cause isn’t something that we can culture and test for” — like hepatitis, or strep throat — “it basically just stays a mystery.”
  • It would be better, DeRisi says, to watch for rare cases of mystery illnesses in people, which often exist well before a pathogen gains traction and is able to spread.
  • Based on a retrospective analysis of blood samples, scientists now know that H.I.V. emerged nearly a dozen times over a century, starting in the 1920s, before it went global.
  • Zika was a relatively harmless illness before a single mutation, in 2013, gave the virus the ability to enter and damage brain cells.
  • The beauty of this approach” — running blood samples from people hospitalized all over the world through his system, known as IDseq — “is that it works even for things that we’ve never seen before, or things that we might think we’ve seen but which are actually something new.”
  • In this scenario, an undiscovered or completely new virus won’t trigger a match but will instead be flagged. (Even in those cases, the mystery pathogen will usually belong to a known virus family: coronaviruses, for instance, or filoviruses that cause hemorrhagic fevers like Ebola and Marburg.)
  • And because different types of bacteria require specific conditions in order to grow, you also need some idea of what you’re looking for in order to find it.
  • The same is true of genomic sequencing, which relies on “primers” designed to match different combinations of nucleotides (the building blocks of DNA and RNA).
  • Even looking at a slide under a microscope requires staining, which makes organisms easier to see — but the stains used to identify bacteria and parasites, for instance, aren’t the same.
  • The practice that DeRisi helped pioneer to skirt this problem is known as metagenomic sequencing
  • Unlike ordinary genomic sequencing, which tries to spell out the purified DNA of a single, known organism, metagenomic sequencing can be applied to a messy sample of just about anything — blood, mud, seawater, snot — which will often contain dozens or hundreds of different organisms, all unknown, and each with its own DNA. In order to read all the fragmented genetic material, metagenomic sequencing uses sophisticated software to stitch the pieces together by matching overlapping segments.
  • The assembled genomes are then compared against a vast database of all known genomic sequences — maintained by the government-run National Center for Biotechnology Information — making it possible for researchers to identify everything in the mix
  • Traditionally, the way that scientists have identified organisms in a sample is to culture them: Isolate a particular bacterium (or virus or parasite or fungus); grow it in a petri dish; and then examine the result under a microscope, or use genomic sequencing, to understand just what it is. But because less than 2 percent of bacteria — and even fewer viruses — can be grown in a lab, the process often reveals only a tiny fraction of what’s actually there. It’s a bit like planting 100 different kinds of seeds that you found in an old jar. One or two of those will germinate and produce a plant, but there’s no way to know what the rest might have grown into.
  • Such studies have revealed just how vast the microbial world is, and how little we know about it
  • “The selling point for researchers is: ‘Look, this technology lets you investigate what’s happening in your clinic, whether it’s kids with meningitis or something else,’” DeRisi said. “We’re not telling you what to do with it. But it’s also true that if we have enough people using this, spread out all around the world, then it does become a global network for detecting emerging pandemics
  • Metagenomic sequencing is especially good at what scientists call “environmental sampling”: identifying, say, every type of bacteria present in the gut microbiome, or in a teaspoon of seawater.
  • After the Biohub opened in 2016, one of DeRisi’s goals was to turn metagenomics from a rarefied technology used by a handful of elite universities into something that researchers around the world could benefit from
  • metagenomics requires enormous amounts of computing power, putting it out of reach of all but the most well-funded research labs. The tool DeRisi created, IDseq, made it possible for researchers anywhere in the world to process samples through the use of a small, off-the-shelf sequencer, much like the one DeRisi had shown me in his lab, and then upload the results to the cloud for analysis.
  • he’s the first to make the process so accessible, even in countries where lab supplies and training are scarce. DeRisi and his team tested the chemicals used to prepare DNA for sequencing and determined that using as little as half the recommended amount often worked fine. They also 3-D print some of the labs’ tools and replacement parts, and offer ongoing training and tech support
  • The metagenomic analysis itself — normally the most expensive part of the process — is provided free.
  • But DeRisi’s main innovation has been in streamlining and simplifying the extraordinarily complex computational side of metagenomics
  • IDseq is also fast, capable of doing analyses in hours that would take other systems weeks.
  • “What IDseq really did was to marry wet-lab work — accumulating samples, processing them, running them through a sequencer — with the bioinformatic analysis,”
  • “Without that, what happens in a lot of places is that the researcher will be like, ‘OK, I collected the samples!’ But because they can’t analyze them, the samples end up in the freezer. The information just gets stuck there.”
  • Meningitis itself isn’t a disease, just a description meaning that the tissues around the brain and spinal cord have become inflamed. In the United States, bacterial infections can cause meningitis, as can enteroviruses, mumps and herpes simplex. But a high proportion of cases have, as doctors say, no known etiology: No one knows why the patient’s brain and spinal tissues are swelling.
  • When Saha and her team ran the mystery meningitis samples through IDseq, though, the result was surprising. Rather than revealing a bacterial cause, as expected, a third of the samples showed signs of the chikungunya virus — specifically, a neuroinvasive strain that was thought to be extremely rare. “At first we thought, It cannot be true!” Saha recalls. “But the moment Joe and I realized it was chikungunya, I went back and looked at the other 200 samples that we had collected around the same time. And we found the virus in some of those samples as well.”
  • Until recently, chikungunya was a comparatively rare disease, present mostly in parts of Central and East Africa. “Then it just exploded through the Caribbean and Africa and across Southeast Asia into India and Bangladesh,” DeRisi told me. In 2011, there were zero cases of chikungunya reported in Latin America. By 2014, there were a million.
  • Chikungunya is a mosquito-borne virus, but when DeRisi and Saha looked at the results from IDseq, they also saw something else: a primate tetraparvovirus. Primate tetraparvoviruses are almost unknown in humans, and have been found only in certain regions. Even now, DeRisi is careful to note, it’s not clear what effect the virus has on people. “Maybe it’s dangerous, maybe it isn’t,” DeRisi says. “But I’ll tell you what: It’s now on my radar.
  • it reveals a landscape of potentially dangerous viruses that we would otherwise never find out about. “What we’ve been missing is that there’s an entire universe of pathogens out there that are causing disease in humans,” Imam notes, “ones that we often don’t even know exist.”
  • “The plan was, Let’s let researchers around the world propose studies, and we’ll choose 10 of them to start,” DeRisi recalls. “We thought we’d get, like, a couple dozen proposals, and instead we got 350.”
  • One study found more than 1,000 different kinds of viruses in a tiny amount of human stool; another found a million in a couple of pounds of marine sediment. And most were organisms that nobody had seen before.
  • “When you draw blood from someone who has a fever in Ghana, you really don’t know very much about what would normally be in their blood without fever — let alone about other kinds of contaminants in the environment. So how do you interpret the relevance of all the things you’re seeing?”
  • Such criticisms have led some to say that metagenomics simply isn’t suited to the infrastructure of developing countries. Along with the problem of contamination, many labs struggle to get the chemical reagents needed for sequencing, either because of the cost or because of shipping and customs holdups
  • we’re less likely to be caught off-guard. “With Ebola, there’s always an issue: Where’s the virus hiding before it breaks out?” DeRisi explains. “But also, once we start sampling people who are hospitalized more widely — meaning not just people in Northern California or Boston, but in Uganda, and Sierra Leone, and Indonesia — the chance of disastrous surprises will go down. We’ll start seeing what’s hidden.”

Opinion: No more union-busting. It's time for companies to give their workers what they... - 0 views

  • This year, workers at Amazon, Starbucks and other major corporations are winning a wave of union elections, often in the face of long odds and employer resistance. These wins are showing it's possible for determined groups of workers to break through powerful employers' use of union-busting tactics, ranging from alleged retaliatory firings to alleged surveillance and forced attendance at anti-union "captive audience meetings." But workers should not have to confront so many obstacles to exercising a guaranteed legal right to unionize and bargain for improvements in their work lives and livelihoods.
  • For decades, wage suppression, growing income inequality and persistent racial and gender wage gaps have characterized the US labor market.
  • But now, as workers are pointing the way to better workplaces and a more equitable economy, employers and policymakers need to pay attention. Policymakers must better protect workers' union rights, and employers must start respecting workers' right to participate in union elections without interference or coercion.
  • ...8 more annotations...
  • Unions are among the most effective mechanisms available for addressing massive economic inequalities. Congress should adopt labor law reforms to better protect workers' right to organize, starting with the widely popular Protecting the Right to Organize (PRO) Act. Among other things, the PRO Act would create the first serious monetary penalties for employers that retaliate against workers for unionizing.
  • Congress must also adequately fund the National Labor Relations Board (NLRB) so the agency can enforce labor law.
  • Many US workers say they want a union, but far too few have one. Right now, workers who've won recent union elections are inviting employers to meet them as equals and start bargaining union contracts.
  • Labor unions are highly correlated with safer conditions because they give workers a voice in setting workplace policies and the ability to engage management in addressing concerns without fear of retaliation.
  • The Black-led, multiracial committees that have led organizing drives at Amazon warehouses and the young women baristas leading breakthrough organizing victories at Starbucks are changing the public face of the labor movement in powerful and promising ways.
  • Two-thirds of union workers are women and/or workers of color.
  • In any company, the transparency and consistency of a union contract that sets wage rates, scheduled raises and procedures for promotions helps guard against forms of discriminatory bias that otherwise disadvantage women and workers of color.
  • Unionizing workers will continue to need extraordinary solidarity, persistence and public support in order to succeed. This is a moment of opportunity for all of us. Anyone ready to start reversing the worst economic inequalities the US has seen in almost a century can choose now to join and support workers who are organizing unions.

The New York Times' trans coverage is under fire. The paper needs to listen | Arwa Mahd... - 0 views

  • I’ve got a feeling the poor alien might get the impression that every third person in the US is trans – rather than 0.5% of the population. They (I assume aliens are nonbinary) might get the impression that nobody is allowed to say the word “woman” any more and we are all being forced at gunpoint to say “uterus-havers”. They might get the impression that women’s sports have been completely taken over by trans women. They might believe that millions of children are being mutilated by doctors in the name of gender-affirming care because of the all-powerful trans lobby. They might come away thinking that JK Rowling is not a multi-multi-multi-millionaire with endless resources at her disposal but a marginalized victim who needs brave Times columnists to come to her defense.
  • “In the past eight months the Times has now published more than 15,000 words’ worth of front-page stories asking whether care and support for young trans people might be going too far or too fast”. Those, to reiterate, are newspaper front-page stories. As Popula notes, that number “doesn’t include the 11,000 or so words the New York Times Magazine devoted to a laboriously evenhanded story about disagreements over the standards of care for trans youth; or the 3,000 words of the front-page story … on whether trans women athletes are unfairly ruining the competition for other women; or the 1,200 words of the front-page story … on how trans interests are banning the word “woman” from abortion-rights discourse.”
  • This letter, addressed to the paper’s associate managing editor for standards, accused the Times of treating gender diversity “with an eerily familiar mix of pseudoscience and euphemistic, charged language, while publishing reporting on trans children that omits relevant information about its sources”. That relevant information being that some of those sources have affiliations with far-right groups. That “charged language” being phrases like “patient zero” to describe a transgender young person seeking gender-affirming care, “a phrase that vilifies transness as a disease to be feared”.

  • “It is not unusual for outside groups to critique our coverage or to rally supporters to seek to influence our journalism,” Kahn wrote in the memo. “In this case, however, members of our staff and contributors to The Times joined the effort … We do not welcome, and will not tolerate, participation by Times journalists in protests organized by advocacy groups or attacks on colleagues on social media and other public forums.”
  • Charlie Stadtlander, the Times’ director of external communication, put out a statement stating that the organization pursues “independent reporting on transgender issues that include profiling groundbreakers in the movement, challenges and prejudice faced by the community, and how society is grappling with debates about care”. While that was all very diplomatic, the executive editor, Joe Kahn, and opinion editor, Kathleen Kingsbury, sent around a rather more pointed newsroom memo condemning the letters on Thursday.
  • The second letter was signed by more than 100 LGBTQ+ and civil rights groups, including Glaad and the Human Rights Campaign. It expressed support for the contributor letter and accused the Times of platforming “fringe theories” and “dangerous inaccuracies”. It noted that while the Times has produced responsible coverage of trans people, “those articles are not getting front-page placement or sent to app users via push notification like the irresponsible pieces are”. And it observed that rightwing politicians have been using the Times’s coverage of trans issues to justify criminalizing gender-affirming care.
  • Here’s the thing: there is no clear-cut line between advocacy and journalism. All media organizations have a perspective about the world and filter their output (which will, of course, strive to be fairly reported) through that perspective. To pretend otherwise is dishonest. Like it or not, the Times is involved in advocacy. It just needs to step back for a moment and think about who it’s advocating for.

Facebook will start telling you when a story may be fake - The Washington Post - 0 views

  • The social network is going to partner with the Poynter International Fact-Checking Network,&nbsp;which includes groups&nbsp;such as Snopes&nbsp;and the Associated Press, to evaluate articles flagged by Facebook users. If those articles do not pass the smell test for the fact-checkers, Facebook will label that evaluation whenever they are posted or shared, along with a link to the organization that debunked the story.
  • Mosseri said the social network still wants to be a place where&nbsp;people with all kinds of opinions can express themselves&nbsp;but has no interest in being the arbiter of what’s true and what's not for its 1 billion users.
  • The new system will work like this: If a story on Facebook is patently false — saying that a celebrity is dead when they are still alive, for example — then users will see a notice that the story has been disputed or debunked. People who try to&nbsp;share stories that have been found false will also see an alert before they post. Flagged stories will appear lower in the news feed than unflagged stories.
  • ...9 more annotations...
  • Users will also be able to report potentially false stories to Facebook or send messages directly to the person posting a questionable article.
  • The company is focusing, for now, on what Mosseri called the “bottom of the barrel” websites&nbsp;that are purposefully set up to deceive and spread fake news, as well as those that are impersonating other news organizations. “We are not looking to flag legitimate organizations,” Mosseri said. “We’re looking for pages posing as legitimate organizations.” Articles from legitimate sites that are controversial or even wrong should not get flagged, he said.
  • The company will also prioritize checking stories that are getting lots of flags from users and are being shared widely, to go after the biggest targets possible.
  • "From a journalistic side, is it enough? It’s a little late.”
  • Facebook is fine to filter out other content -- such as pornography -- for which the definition is unclear. There's no clear explanation for why Facebook hasn't decided to apply similar filters to fake news.&nbsp;“I think that’s a little weak,” Tu said. “If you recognize that it’s bad and journalists at the AP say it’s bad, you shouldn’t have it on your site.”
  • Others said Facebook's careful approach may be warranted. "I think we'll have to wait and see early results to determine how effective the strategy is," said Alexios Mantzarlis, of Poynter's International Fact-Checking Network. "In my eyes, erring on the side of caution is not a bad idea with something so complicated," he said
  • Facebook is also trying to crack down on people who have made a business in&nbsp;fake news by tweaking&nbsp;the social network's advertising practices. Any article that has been disputed, for example, cannot be used in an ad. Facebook&nbsp;is also playing around with ways to limit links from publishers with landing pages that are mostly ads — a common tactic for fake-news websites
  • With those measures in place, “we’re hoping financially motivated spammers might move away from fake news,” Mosseri said
  • Paul Horner, a fake news writer who makes a living writing viral hoaxes, said he wasn't immediately worried about Facebook's new crackdown on fake news sites. "It's really easy to start a new site. I have 50 domain names. I have a dedicated server. I can start up a new site within 48 hours," he said, shortly after Facebook announced its new anti-hoax programs.&nbsp; If his sites, which he describes as "satire"-focused, do end up getting hit too hard, Horner says he has "backup plans."

There’s no one else out there who has been able to include more than a handful of functions or more than, say, one-third of the genes.”
  • The simulation, which runs on a cluster of 128 computers, models the complete life span of the cell at the molecular level, charting the interactions of 28 categories of molecules — including DNA, RNA, proteins and small molecules known as metabolites, which are generated by cell processes.
  • They called the simulation an important advance in the new field of computational biology, which has recently yielded such achievements as the creation of a synthetic life form — an entire bacterial genome created by a team led by the genome pioneer J. Craig Venter. The scientists used it to take over an existing cell.
  • A decade ago, scientists developed simulations of metabolism that are now being used to study a wide array of cells, including bacteria, yeast and photosynthetic organisms. Other models exist for processes like protein synthesis.
  • “Right now, running a simulation for a single cell to divide only one time takes around 10 hours and generates half a gigabyte of data,” Dr. Covert wrote. “I find this fact completely fascinating, because I don’t know that anyone has ever asked how much data a living thing truly holds. We often think of the DNA as the storage medium, but clearly there is more to it than that.”
  • scientists chose an approach called object-oriented programming, which parallels the design of modern software systems. Software designers organize their programs in modules, which communicate with one another by passing data and instructions back and forth.
  • “The major modeling insight we had a few years ago was to break up the functionality of the cell into subgroups, which we could model individually, each with its own mathematics, and then to integrate these submodels together into a whole,”

  • Past critical transformations of thought can help us see how we need to transform ourselves now in order to survive the future.
  • something both ancient and immediate: the way we define who is in our tribe plays a critical role in what kind of social organization we can build and maintain
  • ...25 more annotations...
  • You can’t have a blood family of 300 million, nor even a large enough one to do things like build an agrarian society
  • In order to have large cities built on agrarianism it was necessary not only to innovate technology, but to transform our very consciousness as it related to how we defined what a person was, both ourselves and others
  • Instead of needing to have real, flowing blood with common DNA from birth, it was merely necessary to be among the same abstract family organized under a king of some kind — a kind of stand in for the father or patriarch. We developed law and law enforcement as abstract disembodied voices of the father. This allowed total strangers without any family ties to interact in the same society in a constructive and organized way. Thus: civilization as we know it
  • Those ancient polities have developed finally into the Nation, a kind of tribe so fully abstracted that you can be of any blood and language and religion and still function within it.
  • So, too, are all other forms of human separation — and the opposition and conflicts they spawn — illusory in nature. We moved beyond blood, but then it was language or religion or fealty that made it impossible to work together, and we warred over that
  • we’re told these borders mean everything, that they are real and urgent and demand constant sacrifice to maintain.
  • why is that border there? Why borders?
  • We’re stuck in a mode of thinking that’s no longer sensible. There isn’t a reason for borders. There never really was, but now more than ever we have no utility for them, no need for them
  • What humanity has to do is wake up to the reality of post-tribalism. This means seeing through all these invented borders to the truth that we are all people, we are all fundamentally the same, and we can all learn to live with one another.
  • It was the idea of necessary conflict based on blood that preceded the fights that appeared to justify the belief in that blood-based conflict.
  • Nations have saturated the entire globe. There are no more frontiers. It’s all Nations butting up against one another.
  • We are all people of a similar nature and we do have the option to relate to one another as people for the sake of saving our shared homes and futures. We all hunger and thirst and become lonely, we all laugh and weep in the same language. Stripped of confounding symbols we are undivided.
  • There are a lot of people upset about the illusion of borders. They want a different reality, one in which there are Good Tribes (their tribe) and Bad Tribes (all the other ones).
  • but the world is already so mixed together they can’t draw those borders anymore. Hence: fascism.
  • There are no firm foundations for defining this tribe, however, so he’s left to cobble together some kind of ad hoc notion of in- and out-group. Like a magpie he collects ways of dividing people as appeals to his caprice: race, sex, Nation, etc., but there’s no greater sense to it, so it’s all arbitrary, all a mess.
  • No amount of magical thinking from conservatives can change the reality of globalism, however; what one Nation does to pollute will affect us all, and that is according to the laws of physics. No political movement can change those physics. We have to adapt or perish.
  • a key part of it is a simple lack of imagination. He just doesn’t realize there’s an option to not have borders, because his entire consciousness is married to the idea of of-me and not-of-me, Us and Them, and if there is no Them there can’t be an Us, and therefore life stops making sense
  • What has to be true if there are no tribes? We have no need to discriminate among who we may love. Loving and caring for all people as if they were blood family is the path forward
  • There needs to be a new story for us to share. It’s not enough to stop believing in the old way of borders, we have to actively seek out a new way of thinking and speaking and living that reflects the world as it is and as it can be.
  • there are others who have more tangible investments in borders: Those who have grown fat off the conflicts driven by these invented borders don’t want us to see how pointless it all is. These billionaires and presidents and kings want us to keep fighting against one another over the borders they so lazily define because it gives them a means of power and control.
  • We have to be ready for their opposition, however. They’ll do what they can to force us to act as if their borders are real. We don’t need to listen, though we do need to be ready to sacrifice.
  • Without a globally-coordinated response we can’t resolve a globally-driven problem such as climate change. If we can grant the humanity of all people we can start to imagine ways of relating to one another that aren’t opposed and antagonistic, but which are cooperative and aimed at harmony.
  • This transformation of consciousness must happen in our own hearts and minds before it can happen in concert.
  • the Nation has already been shown to be unnecessary because of social globalism. Pick a major city on earth and you’ll find every kind of person living together in peace! Not perfect peace, but not constant and unavoidable war, and that is what counts.
  • We can’t keep pretending as if borders matter when we can so clearly see that they don’t, but we can’t just have no story at all, there must be a way of contextualizing a future without borders. I don’t know what that story is, exactly, but I believe it is something like love writ large. Once we’re ready to start telling it we can start living it.

Sensory Perception - An Introduction to the Process of Perception - 0 views

  • An individual or organism capable of processing the stimuli&nbsp;in their environment is called to have a sensory perception.
  • This processing is done through the coordination between sense organs and the brain. Hearing, vision, taste, smell, and touch are the five senses we possess. The sensory perception involves detecting, recognizing, characterizing and responding to stimuli.
  • The process of sensory perception begins when something in the real world stimulates our sense organs. For instance, light reflecting from a surface stimulates our eyes. The warmth emanating from a hot cup of beverage stimulates our touch senses.

MacIntyre | Internet Encyclopedia of Philosophy - 0 views

  • For MacIntyre, “rationality” comprises all the intellectual resources, both formal and substantive, that we use to judge truth and falsity in propositions, and to determine choice-worthiness in courses of action
  • Rationality in this sense is not universal; it differs from community to community and from person to person, and may both develop and regress over the course of a person’s life or a community’s history.
  • So rationality itself, whether theoretical or practical, is a concept with a history: indeed, since there are also a diversity of traditions of enquiry, with histories, there are, so it will turn out, rationalities rather than rationality, just as it will also turn out that there are justices rather than justice
  • ...164 more annotations...
  • Rationality is the collection of theories, beliefs, principles, and facts that the human subject uses to judge the world, and a person’s rationality is, to a large extent, the product of that person’s education and moral formation.
  • To the extent that a person accepts what is handed down from the moral and intellectual traditions of her or his community in learning to judge truth and falsity, good and evil, that person’s rationality is “tradition-constituted.” Tradition-constituted rationality provides the schemata by which we interpret, understand, and judge the world we live in
  • The apparent problem of relativism in MacIntyre’s theory of rationality is much like the problem of relativism in the philosophy of science. Scientific claims develop within larger theoretical frameworks, so that the apparent truth of a scientific claim depends on one’s judgment of the larger framework. The resolution of the problem of relativism therefore appears to hang on the possibility of judging frameworks or rationalities, or judging between frameworks or rationalities from a position that does not presuppose the truth of the framework or rationality, but no such theoretical standpoint is humanly possible.
  • MacIntyre finds that the world itself provides the criterion for the testing of rationalities, and he finds that there is no criterion except the world itself that can stand as the measure of the truth of any philosophical theory.
  • MacIntyre’s philosophy is indebted to the philosophy of science, which recognizes the historicism of scientific enquiry even as it seeks a truthful understanding of the world. MacIntyre’s philosophy does not offer a priori certainty about any theory or principle; it examines the ways in which reflection upon experience supports, challenges, or falsifies theories that have appeared to be the best theories so far to the people who have accepted them so far. MacIntyre’s ideal enquirers remain Hamlets, not Emmas.
  • history shows us that individuals, communities, and even whole nations may commit themselves militantly over long periods of their histories to doctrines that their ideological adversaries find irrational. This qualified relativism of appearances has troublesome implications for anyone who believes that philosophical enquiry can easily provide certain knowledge of the world
  • According to MacIntyre, theories govern the ways that we interpret the world and no theory is ever more than “the best standards so far” (3RV, p. 65). Our theories always remain open to improvement, and when our theories change, the appearances of our world—the apparent truths of claims judged within those theoretical frameworks—change with them.
  • From the subjective standpoint of the human enquirer, MacIntyre finds that theories, concepts, and facts all have histories, and they are all liable to change—for better or for worse.
  • MacIntyre holds that the rationality of individuals is not only tradition-constituted, it is also tradition constitutive, as individuals make their own contributions to their own rationality, and to the rationalities of their communities. Rationality is not fixed, within either the history of a community or the life of a person
  • The modern account of first principles justifies an approach to philosophy that rejects tradition. The modern liberal individualist approach is anti-traditional. It denies that our understanding is tradition-constituted and it denies that different cultures may differ in their standards of rationality and justice:
  • Modernity does not see tradition as the key that unlocks moral and political understanding, but as a superfluous accumulation of opinions that tend to prejudice moral and political reasoning.
  • Although modernity rejects tradition as a method of moral and political enquiry, MacIntyre finds that it nevertheless bears all the characteristics of a moral and political tradition.
  • If historical narratives are only projections of the interests of historians, then it is difficult to see how this historical narrative can claim to be truthful
  • For these post-modern theorists, “if the Enlightenment conceptions of truth and rationality cannot be sustained,” either relativism or perspectivism “is the only possible alternative” (p. 353). MacIntyre rejects both challenges by developing his theory of tradition-constituted and tradition-constitutive rationality on pp. 354-369
  • How, then, is one to settle challenges between two traditions? It depends on whether the adherents of either take the challenges of the other tradition seriously. It depends on whether the adherents of either tradition, on seeing a failure in their own tradition are willing to consider an answer offered by their rival (p. 355)
  • how a person with no traditional affiliation is to deal with the conflicting claims of rival traditions: “The initial answer is: that will depend upon who you are and how you understand yourself. This is not the kind of answer which we have been educated to expect in philosophy”
  • MacIntyre focuses the critique of modernity on the question of rational justification. Modern epistemology stands or falls on the possibility of Cartesian epistemological first principles. MacIntyre’s history exposes that notion of first principle as a fiction, and at the same time demonstrates that rational enquiry advances (or declines) only through tradition
  • MacIntyre cites Foucault’s 1966 book, Les Mots et les choses (The Order of Things, 1970) as an example of the self-subverting character of Genealogical enquiry
  • Foucault’s book reduces history to a procession of “incommensurable ordered schemes of classification and representation” none of which has any greater claim to truth than any other, yet this book “is itself organized as a scheme of classification and representation.”
  • From MacIntyre’s perspective, there is no question of deciding whether or not to work within a tradition; everyone who struggles with practical, moral, and political questions simply does. “There is no standing ground, no place for enquiry . . . apart from that which is provided by some particular tradition or other”
  • Three Rival Versions of Moral Enquiry (1990). The central idea of the Gifford Lectures is that philosophers make progress by addressing the shortcomings of traditional narratives about the world, shortcomings that become visible either through the failure of traditional narratives to make sense of experience, or through the introduction of contradictory narratives that prove impossible to dismiss
  • MacIntyre compares three traditions exemplified by three literary works published near the end of Adam Gifford’s life (1820–1887)
  • The Ninth Edition of the Encyclopaedia Britannica (1875–1889) represents the modern tradition of trying to understand the world objectively without the influence of tradition.
  • The Genealogy of Morals (1887), by Friedrich Nietzsche embodies the post-modern tradition of interpreting all traditions as arbitrary impositions of power.
  • The encyclical letter Aeterni Patris (1879) of Pope Leo XIII exemplifies the approach of acknowledging one’s predecessors within one’s own tradition of enquiry and working to advance or improve that tradition in the pursuit of objective truth.&nbsp;
  • Of the three versions of moral enquiry treated in 3RV, only tradition, exemplified in 3RV by the Aristotelian, Thomistic tradition, understands itself as a tradition that looks backward to predecessors in order to understand present questions and move forward
  • Encyclopaedia obscures the role of tradition by presenting the most current conclusions and convictions of a tradition as if they had no history, and as if they represented the final discovery of unalterable truth
  • Encyclopaedists focus on the present and ignore the past.
  • Genealogists, on the other hand, focus on the past in order to undermine the claims of the present.
  • In short, Genealogy denies the teleology of human enquiry by denying (1) that historical enquiry has been fruitful, (2) that the enquiring person has a real identity, and (3) that enquiry has a real goal. MacIntyre finds this mode of enquiry incoherent.
  • Genealogy is self-deceiving insofar as it ignores the traditional and teleological character of its enquiry.
  • Genealogical moral enquiry must make similar exceptions to its treatments of the unity of the enquiring subject and the teleology of moral enquiry; thus “it seems to be the case that the intelligibility of genealogy requires beliefs and allegiances of a kind precluded by the genealogical stance” (3RV, p. 54-55)
  • MacIntyre uses Thomism because it applies the traditional mode of enquiry in a self-conscious manner. Thomistic students learn the work of philosophical enquiry as apprentices in a craft (3RV, p. 61), and maintain the principles of the tradition in their work to extend the understanding of the tradition, even as they remain open to the criticism of those principles.
  • 3RV uses Thomism as its example of tradition, but this use should not suggest that MacIntyre identifies “tradition” with Thomism or Thomism-as-a-name-for-the-Western-tradition. As noted above, WJWR distinguished four traditions of enquiry within the Western European world alone
  • MacIntyre’s emphasis on the temporality of rationality in traditional enquiry makes tradition incompatible with the epistemological projects of modern philosophy
  • Tradition is not merely conservative; it remains open to improvement,
  • Tradition differs from both encyclopaedia and genealogy in the way it understands the place of its theories in the history of human enquiry. The adherent of a tradition must understand that “the rationality of a craft is justified by its history so far,” thus it “is inseparable from the tradition through which it was achieved”
  • MacIntyre uses Thomas Aquinas to illustrate the revolutionary potential of traditional enquiry. Thomas was educated in Augustinian theology and Aristotelian philosophy, and through this education he began to see not only the contradictions between the two traditions, but also the strengths and weaknesses that each tradition revealed in the other. His education also helped him to discover a host of questions and problems that had to be answered and solved. Many of Thomas Aquinas’ responses to these concerns took the form of disputed questions. “Yet to each question the answer produced by Aquinas as a conclusion is no more than and, given Aquinas’s method, cannot but be no more than, the best answer reached so far. And hence derives the essential incompleteness”
  • argue that the virtues are essential to the practice of independent practical reason. The book is relentlessly practical; its arguments appeal only to experience and to purposes, and to the logic of practical reasoning.
  • Like other intelligent animals, human beings enter life vulnerable, weak, untrained, and unknowing, and face the likelihood of infirmity in sickness and in old age. Like other social animals, humans flourish in groups. We learn to regulate our passions, and to act effectively alone and in concert with others through an education provided within a community. MacIntyre’s position allows him to look to the animal world to find analogies to the role of social relationships in the moral formation of human beings
  • The task for the human child is to make “the transition from the infantile exercise of animal intelligence to the exercise of independent practical reasoning” (DRA, p. 87). For a child to make this transition is “to redirect and transform her or his desires, and subsequently to direct them consistently towards the goods of different stages of her or his life” (DRA, p. 87). The development of independent practical reason in the human agent requires the moral virtues in at least three ways.
  • DRA presents moral knowledge as a “knowing how,” rather than as a “knowing that.” Knowledge of moral rules is not sufficient for a moral life; prudence is required to enable the agent to apply the rules well.
  • “Knowing how to act virtuously always involves more than rule-following” (DRA, p. 93). The prudent person can judge what must be done in the absence of a rule and can also judge when general norms cannot be applied to particular cases.
  • Flourishing as an independent practical reasoner requires the virtues in a second way, simply because sometimes we need our friends to tell us who we really are. Independent practical reasoning also requires self-knowledge, but self-knowledge is impossible without the input of others whose judgment provides a reliable touchstone to test our beliefs about ourselves. Self-knowledge therefore requires the virtues that enable an agent to sustain formative relationships and to accept the criticism of trusted friends
  • Human flourishing requires the virtues in a third way, by making it possible to participate in social and political action. They enable us to “protect ourselves and others against neglect, defective sympathies, stupidity, acquisitiveness, and malice” (DRA, p. 98) by enabling us to form and sustain social relationships through which we may care for one another in our infirmities, and pursue common goods with and for the other members of our societies.
  • MacIntyre argues that it is impossible to find an external standpoint, because rational enquiry is an essentially social work (DRA, p. 156-7). Because it is social, shared rational enquiry requires moral commitment to, and practice of, the virtues to prevent the more complacent members of communities from closing off critical reflection upon “shared politically effective beliefs and concepts”
  • MacIntyre finds himself compelled to answer what may be called the question of moral provincialism: If one is to seek the truth about morality and justice, it seems necessary to “find a standpoint that is sufficiently external to the evaluative attitudes and practices that are to be put to the question.” If it is impossible for the agent to take such an external standpoint, if the agent’s commitments preclude radical criticism of the virtues of the community, does that leave the agent “a prisoner of shared prejudices” (DRA, p. 154)?
  • The book moves from MacIntyre’s assessment of human needs for the virtues to the political implications of that assessment. Social and political institutions that form and enable independent practical reasoning must “satisfy three conditions.” (1) They must enable their members to participate in shared deliberations about the communities’ actions. (2) They must establish norms of justice “consistent with exercise of” the virtue of justice. (3) They must enable the strong “to stand proxy” as advocates for the needs of the weak and the disabled.
  • The social and political institutions that MacIntyre recommends cannot be identified with the modern nation state or the modern nuclear family
  • The political structures necessary for human flourishing are essentially local
  • Yet local communities support human flourishing only when they actively support “the virtues of just generosity and shared deliberation”
  • MacIntyre rejects individualism and insists that we view human beings as members of communities who bear specific debts and responsibilities because of our social identities. The responsibilities one may inherit as a member of a community include debts to one’s forbearers that one can only repay to people in the present and future
  • The constructive argument of the second half of the book begins with traditional accounts of the excellences or virtues of practical reasoning and practical rationality rather than virtues of moral reasoning or morality. These traditional accounts define virtue as arête, as excellence
  • Practices are supported by institutions like chess clubs, hospitals, universities, industrial corporations, sports leagues, and political organizations.
  • Practices exist in tension with these institutions, since the institutions tend to be oriented to goods external to practices. Universities, hospitals, and scholarly societies may value prestige, profitability, or relations with political interest groups above excellence in the practices they are said to support.
  • Personal desires and institutional pressures to pursue external goods may threaten to derail practitioners’ pursuits of the goods internal to practices. MacIntyre defines virtue initially as the quality of character that enables an agent to overcome these temptations:
  • “A virtue is an acquired human quality the possession and exercise of which tends to enable us to achieve those goods which are internal to practices
  • Excellence as a human agent cannot be reduced to excellence in a particular practice (See AV, pp. 204–
  • The virtues therefore are to be understood as those dispositions which will not only sustain practices and enable us to achieve the goods internal to practices, but which will also sustain us in the relevant kind of quest for the good, by enabling us to overcome the harms, dangers, temptations, and distractions which we encounter, and which will furnish us with increasing self-knowledge and increasing knowledge of the good (AV, p. 219).
  • The excellent human agent has the moral qualities to seek what is good and best both in practices and in life as a whole.
  • The virtues find their point and purpose not only in sustaining those relationships necessary if the variety of goods internal to practices are to be achieved and not only in sustaining the form of an individual life in which that individual may seek out his or her good as the good of his or her whole life, but also in sustaining those traditions which provide both practices and individual lives with their necessary historical context (AV, p. 223)
  • Since “goods, and with them the only grounds for the authority of laws and virtues, can only be discovered by entering into those relationships which constitute communities whose central bond is a shared vision of and understanding of goods” (AV, p. 258), any hope for the transformation and renewal of society depends on the development and maintenance of such communities.
  • MacIntyre’s Aristotelian approach to ethics as a study of human action distinguishes him from post-Kantian moral philosophers who approach ethics as a means of determining the demands of objective, impersonal, universal morality
  • This modern approach may be described as moral epistemology. Modern moral philosophy pretends to free the individual to determine for her- or himself what she or he must do in a given situation, irrespective of her or his own desires; it pretends to give knowledge of universal moral laws
  • Aristotelian metaphysicians, particularly Thomists who define virtue in terms of the perfection of nature, rejected MacIntyre’s contention that an adequate Aristotelian account of virtue as excellence in practical reasoning and human action need not appeal to Aristotelian metaphysic
  • one group of critics rejects MacIntyre’s Aristotelianism because they hold that any Aristotelian account of the virtues must first account for the truth about virtue in terms of Aristotle’s philosophy of nature, which MacIntyre had dismissed in AV as “metaphysical biology”
  • Many of those who rejected MacIntyre’s turn to Aristotle define “virtue” primarily along moral lines, as obedience to law or adherence to some kind of natural norm. For these critics, “virtuous” appears synonymous with “morally correct;” their resistance to MacIntyre’s appeal to virtue stems from their difficulties either with what they take to be the shortcomings of MacIntyre’s account of moral correctness or with the notion of moral correctness altogether
  • MacIntyre continues to argue from the experience of practical reasoning to the demands of moral education.
  • Descartes and his successors, by contrast, along with certain “notable Thomists of the last hundred years” (p. 175), have proposed that philosophy begins from knowledge of some “set of necessarily true first principles which any truly rational person is able to evaluate as true” (p. 175). Thus for the moderns, philosophy is a technical rather than moral endeavor
  • MacIntyre distinguishes two related challenges to his position, the “relativist challenge” and the “perspectivist challenge.” These two challenges both acknowledge that the goals of the Enlightenment cannot be met and that, “the only available standards of rationality are those made available by and within traditions” (p. 252); they conclude that nothing can be known to be true or false
  • MacIntyre follows the progress of the Western tradition through “three distinct traditions:” from Homer and Aristotle to Thomas Aquinas, from Augustine to Thomas Aquinas and from Augustine through Calvin to Hume
  • Chapter 17 examines the modern liberal denial of tradition, and the ironic transformation of liberalism into the fourth tradition to be treated in the book.
  • MacIntyre credits John Stuart Mill and Thomas Aquinas as “two philosophers of the kind who by their writing send us beyond philosophy into immediate encounter with the ends of life
  • First, both were engaged by questions about the ends of life as questioning human beings and not just as philosophers. . . .
  • Secondly, both Mill and Aquinas understood their speaking and writing as contributing to an ongoing philosophical conversation. . . .
  • Thirdly, it matters that both the end of the conversation and the good of those who participate in it is truth and that the nature of truth, of good, of rational justification, and of meaning therefore have to be central topics of that conversation (Tasks, pp. 130-1).
  • Without these three characteristics, philosophy is first reduced to “the exercise of a set of analytic and argumentative skills. . . . Secondly, philosophy may thereby become a diversion from asking questions about the ends of life with any seriousness”
  • Neither Rosenzweig nor Lukács made philosophical progress because both failed to relate “their questions about the ends of life to the ends of their philosophical writing”
  • First, any adequate philosophical history or biography must determine whether the authors studied remain engaged with the questions that philosophy studies, or set the questions aside in favor of the answers. Second, any adequate philosophical history or biography must determine whether the authors studied insulated themselves from contact with conflicting worldviews or remained open to learning from every available philosophical approach. Third, any adequate philosophical history or biography must place the authors studied into a broader context that shows what traditions they come from and “whose projects” they are “carrying forward
  • MacIntyre’s recognition of the connection between an author’s pursuit of the ends of life and the same author’s work as a philosophical writer prompts him to finish the essay by demanding three things of philosophical historians and biographers
  • Philosophy is not just a study; it is a practice. Excellence in this practice demands that an author bring her or his struggles with the questions of the ends of philosophy into dialogue with historic and contemporary texts and authors in the hope of making progress in answering those questions
  • MacIntyre defends Thomistic realism as rational enquiry directed to the discovery of truth.
  • The three Thomistic essays in this book challenge those caricatures by presenting Thomism in a way that people outside of contemporary Thomistic scholarship may find surprisingly flexible and open
  • To be a moral agent, (1) one must understand one’s individual identity as transcending all the roles that one fills; (2) one must see oneself as a practically rational individual who can judge and reject unjust social standards; and (3) one must understand oneself as “as accountable to others in respect of the human virtues and not just in respect of [one’s] role-performances
  • J is guilty because he complacently accepted social structures that he should have questioned, structures that undermined his moral agency. This essay shows that MacIntyre’s ethics of human agency is not just a descriptive narrative about the manner of moral education; it is a standard laden account of the demands of moral agency.
  • MacIntyre considers “the case of J” (J, for jemand, the German word for “someone”), a train controller who learned, as a standard for his social role, to take no interest in what his trains carried, even during war time when they carried “munitions and . . . Jews on their way to extermination camps”
  • J had learned to do his work for the railroad according to one set of standards and to live other parts of his life according to other standards, so that this compliant participant in “the final solution” could contend, “You cannot charge me with moral failure” (E&amp;P, p. 187).
  • The epistemological theories of Modern moral philosophy were supposed to provide rational justification for rules, policies, and practical determinations according to abstract universal standards, but MacIntyre has dismissed those theorie
  • Modern metaethics is supposed to enable its practitioners to step away from the conflicting demands of contending moral traditions and to judge those conflicts from a neutral position, but MacIntyre has rejected this project as well
  • In his ethical writings, MacIntyre seeks only to understand how to liberate the human agent from blindness and stupidity, to prepare the human agent to recognize what is good and best to do in the concrete circumstances of that agent’s own life, and to strengthen the agent to follow through on that judgment.
  • In his political writings, MacIntyre investigates the role of communities in the formation of effective rational agents, and the impact of political institutions on the lives of communities. This kind of ethics and politics is appropriately named the ethics of human agency.
  • The purpose of the modern moral philosophy of authors like Kant and Mill was to determine, rationally and universally, what kinds of behavior ought to be performed—not in terms of the agent’s desires or goals, but in terms of universal, rational duties. Those theories purported to let agents know what they ought to do by providing knowledge of duties and obligations, thus they could be described as theories of moral epistemology.
  • Contemporary virtue ethics purports to let agents know what qualities human beings ought to have, and the reasons that we ought to have them, not in terms of our fitness for human agency, but in the same universal, disinterested, non-teleological terms that it inherits from Kant and Mill.
  • For MacIntyre, moral knowledge remains a “knowing how” rather than a “knowing that;” MacIntyre seeks to identify those moral and intellectual excellences that make human beings more effective in our pursuit of the human good.
  • MacIntyre’s purpose in his ethics of human agency is to consider what it means to seek one’s good, what it takes to pursue one’s good, and what kind of a person one must become if one wants to pursue that good effectively as a human agent.
  • As a philosophy of human agency, MacIntyre’s work belongs to the traditions of Aristotle and Thomas Aquinas.
  • in keeping with the insight of Marx’s third thesis on Feuerbach, it maintained the common condition of theorists and people as peers in the pursuit of the good life.
  • He holds that the human good plays a role in our practical reasoning whether we recognize it or not, so that some people may do well without understanding why (E&amp;P, p. 25). He also reads Aristotle as teaching that knowledge of the good can make us better agents
  • AV defines virtue in terms of the practical requirements for excellence in human agency, in an agent’s participation in practices (AV, ch. 14), in an agent’s whole life, and in an agent’s involvement in the life of her or his community
  • MacIntyre’s Aristotelian concept of “human action” opposes the notion of “human behavior” that prevailed among mid-twentieth-century determinist social scientists. Human actions, as MacIntyre understands them, are acts freely chosen by human agents in order to accomplish goals that those agents pursue
  • Human behavior, according to mid-twentieth-century determinist social scientists, is the outward activity of a subject, which is said to be caused entirely by environmental influences beyond the control of the subject.
  • Rejecting crude determinism in social science, and approaches to government and public policy rooted in determinism, MacIntyre sees the renewal of human agency and the liberation of the human agent as central goals for ethics and politics.
  • MacIntyre’s Aristotelian account of “human action” examines the habits that an agent must develop in order to judge and act most effectively in the pursuit of truly choice-worthy ends
  • MacIntyre seeks to understand what it takes for the human person to become the kind of agent who has the practical wisdom to recognize what is good and best to do and the moral freedom to act on her or his best judgment.
  • MacIntyre rejected the determinism of modern social science early in his career (“Determinism,” 1957), yet he recognizes that the ability to judge well and act freely is not simply given; excellence in judgment and action must be developed, and it is the task of moral philosophy to discover how these excellences or virtues of the human agent are established, maintained, and strengthened
  • MacIntyre’s Aristotelian philosophy investigates the conditions that support free and deliberate human action in order to propose a path to the liberation of the human agent through participation in the life of a political community that seeks its common goods through the shared deliberation and action of its members
  • As a classics major at Queen Mary College in the University of London (1945-1949), MacIntyre read the Greek texts of Plato and Aristotle, but his studies were not limited to the grammars of ancient languages. He also examined the ethical theories of Immanuel Kant and John Stuart Mill. He attended the lectures of analytic philosopher A. J. Ayer and of philosopher of science Karl Popper. He read Ludwig Wittgenstein’s Tractatus Logico Philosophicus, Jean-Paul Sartre’s L'existentialisme est un humanisme, and Marx’s Eighteenth Brumaire of Napoleon Bonaparte (What happened, pp. 17-18). MacIntyre met the sociologist Franz Steiner, who helped direct him toward approaching moralities substantively
  • Alasdair MacIntyre’s philosophy builds on an unusual foundation. His early life was shaped by two conflicting systems of values. One was “a Gaelic oral culture of farmers and fishermen, poets and storytellers.” The other was modernity, “The modern world was a culture of theories rather than stories” (MacIntyre Reader, p. 255). MacIntyre embraced both value systems
  • From Marxism, MacIntyre learned to see liberalism as a destructive ideology that undermines communities in the name of individual liberty and consequently undermines the moral formation of human agents
  • For MacIntyre, Marx’s way of seeing through the empty justifications of arbitrary choices to consider the real goals and consequences of political actions in economic and social terms would remain the principal insight of Marxism
  • After his retirement from teaching, MacIntyre has continued his work of promoting a renewal of human agency through an examination of the virtues demanded by practices, integrated human lives, and responsible engagement with community life. He is currently affiliated with the Centre for Contemporary Aristotelian Studies in Ethics and Politics (CASEP) at London Metropolitan University.
  • The second half of AV proposes a conception of practice and practical reasoning and the notion of excellence as a human agent as an alternative to modern moral philosophy
  • AV rejects the view of “modern liberal individualism” in which autonomous individuals use abstract moral principles to determine what they ought to do. The critique of modern normative ethics in the first half of AV rejects modern moral reasoning for its failure to justify its premises, and criticizes the frequent use of the rhetoric of objective morality and scientific necessity to manipulate people to accept arbitrary decisions
  • MacIntyre uses “modern liberal individualism” to name a much broader category that includes both liberals and conservatives in contemporary American political parlance, as well as some Marxists and anarchists (See ASIA, pp. 280-284). Conservatism, liberalism, Marxism, and anarchism all present the autonomous individual as the unit of civil society
  • The sources of modern liberal individualism—Hobbes, Locke, and Rousseau—assert that human life is solitary by nature and social by habituation and convention. MacIntyre’s Aristotelian tradition holds, on the contrary, that human life is social by nature.
  • MacIntyre identifies moral excellence with effective human agency, and seeks a political environment that will help to liberate human agents to recognize and seek their own goods, as components of the common goods of their communities, more effectively. For MacIntyre therefore, ethics and politics are bound together.
  • For MacIntyre ethics is not an application of principles to facts, but a study of moral action. Moral action, free human action, involves decisions to do things in pursuit of goals, and it involves the understanding of the implications of one’s actions for the whole variety of goals that human agents seek
  • In this sense, “To act morally is to know how to act” (SMJ, p. 56). “Morality is not a ‘knowing that’ but a ‘knowing how’”
  • If human action is a ‘knowing how,’ then ethics must also consider how one learns ‘how.’ Like other forms of ‘knowing how,’ MacIntyre finds that one learns how to act morally within a community whose language and shared standards shape our judgment
  • MacIntyre had concluded that ethics is not an abstract exercise in the assessment of facts; it is a study of free human action and of the conditions that enable rational human agency.
  • MacIntyre gives Marx credit for concluding in the third of the Theses on Feuerbach, that the only way to change society is to change ourselves, and that “The coincidence of the changing of human activity or self-changing can only be comprehended and rationally understood as revolutionary practice”
  • MacIntyre distinguishes “religion which is an opiate for the people from religion which is not” (MI, p. 83). He condemns forms of religion that justify social inequities and encourage passivity. He argues that authentic Christian teaching criticizes social structures and encourages action
  • Where “moral philosophy textbooks” discuss the kinds of maxims that should guide “promise-keeping, truth-telling, and the like,” moral maxims do not guide real agents in real life at all. “They do not guide us because we do not need to be guided. We know what to do” (ASIA, p. 106). Sometimes we do this without any maxims at all, or even against all the maxims we know. MacIntyre Illustrates his point with Huckleberry Finn’s decision to help Jim, Miss Watson’s escaped slave, to make his way to freedom
  • MacIntyre develops the ideas that morality emerges from history, and that morality organizes the common life of a community
  • The book concludes that the concepts of morality are neither timeless nor ahistorical, and that understanding the historical development of ethical concepts can liberate us “from any false absolutist claims” (SHE, p. 269). Yet this conclusion need not imply that morality is essentially arbitrary or that one could achieve freedom by liberating oneself from the morality of one’s society.
  • From this “Aristotelian point of view,” “modern morality” begins to go awry when moral norms are separated from the pursuit of human goods and moral behavior is treated as an end in itself. This separation characterizes Christian divine command ethics since the fourteenth century and has remained essential to secularized modern morality since the eighteenth century
  • From MacIntyre’s “Aristotelian point of view,” the autonomy granted to the human agent by modern moral philosophy breaks down natural human communities and isolates the individual from the kinds of formative relationships that are necessary to shape the agent into an independent practical reasoner.
  • the 1977 essay “Epistemological Crises, Dramatic Narrative, and the Philosophy of Science” (Hereafter EC). This essay, MacIntyre reports, “marks a major turning-point in my thought in the 1970s” (The Tasks of Philosophy, p. vii) EC may be described fairly as MacIntyre’s discourse on method
  • First, Philosophy makes progress through the resolution of problems. These problems arise when the theories, histories, doctrines and other narratives that help us to organize our experience of the world fail us, leaving us in “epistemological crises.” Epistemological crises are the aftermath of events that undermine the ways that we interpret our world
  • it presents three general points on the method for philosophy.
  • To live in an epistemological crisis is to be aware that one does not know what one thought one knew about some particular subject and to be anxious to recover certainty about that subject.
  • To resolve an epistemological crisis it is not enough to impose some new way of interpreting our experience, we also need to understand why we were wrong before: “When an epistemological crisis is resolved, it is by the construction of a new narrative which enables the agent to understand both how he or she could intelligibly have held his or her original beliefs and how he or she could have been so drastically misled by them
  • MacIntyre notes, “Philosophers have customarily been Emmas and not Hamlets” (p. 6); that is, philosophers have treated their conclusions as accomplished truths, rather than as “more adequate narratives” (p. 7) that remain open to further improvement.
  • To illustrate his position on the open-endedness of enquiry, MacIntyre compares the title characters of Shakespeare’s Hamlet and Jane Austen’s Emma. When Emma finds that she is deeply misled in her beliefs about the other characters in her story, Mr. Knightly helps her to learn the truth and the story comes to a happy ending (p. 6). Hamlet, by contrast, finds no pat answers to his questions; rival interpretations remain throughout the play, so that directors who would stage the play have to impose their own interpretations on the script
  • Another approach to education is the method of Descartes, who begins by rejecting everything that is not clearly and distinctly true as unreliable and false in order to rebuild his understanding of the world on a foundation of undeniable truth.
  • Descartes presents himself as willfully rejecting everything he had believed, and ignores his obvious debts to the Scholastic tradition, even as he argues his case in French and Latin. For MacIntyre, seeking epistemological certainty through universal doubt as a precondition for enquiry is a mistake: “it is an invitation not to philosophy but to mental breakdown, or rather to philosophy as a means of mental breakdown.
  • MacIntyre contrasts Descartes’ descent into mythical isolation with Galileo, who was able to make progress in astronomy and physics by struggling with the apparently insoluble questions of late medieval astronomy and physics, and radically reinterpreting the issues that constituted those questions
  • To make progress in philosophy one must sort through the narratives that inform one’s understanding, struggle with the questions that those narratives raise, and on occasion, reject, replace, or reinterpret portions of those narratives and propose those changes to the rest of one’s community for assessment. Human enquiry is always situated within the history and life of a community.
  • The third point of EC is that we can learn about progress in philosophy from the philosophy of science
  • Kuhn’s “paradigm shifts,” however, are unlike MacIntyre’s resolutions of epistemological crises in two ways.
  • First they are not rational responses to specific problems. Kuhn compares paradigm shifts to religious conversions (pp. 150, 151, 158), stressing that they are not guided by rational norms and he claims that the “mopping up” phase of a paradigm shift is a matter of convention in the training of new scientists and attrition among the holdouts of the previous paradigm
  • Second, the new paradigm is treated as a closed system of belief that regulates a new period of “normal science”; Kuhn’s revolutionary scientists are Emmas, not Hamlets
  • MacIntyre proposes elements of Imre Lakatos’ philosophy of science as correctives to Kuhn’s. While Lakatos has his own shortcomings, his general account of the methodologies of scientific research programs recognizes the role of reason in the transitions between theories and between research programs (Lakatos’ analog to Kuhn’s paradigms or disciplinary matrices). Lakatos presents science as an open ended enquiry, in which every theory may eventually be replaced by more adequate theories. For Lakatos, unlike Kuhn, rational scientific progress occurs when a new theory can account both for the apparent promise and for the actual failure of the theory it replaces.
  • The third conclusion of MacIntyre’s essay is that decisions to support some theories over others may be justified rationally to the extent that those theories allow us to understand our experience and our history, including the history of the failures of inadequate theories
  • For Aristotle, moral philosophy is a study of practical reasoning, and the excellences or virtues that Aristotle recommends in the Nicomachean Ethics are the intellectual and moral excellences that make a moral agent effective as an independent practical reasoner.
  • MacIntyre also finds that the contending parties have little interest in the rational justification of the principles they use. The language of moral philosophy has become a kind of moral rhetoric to be used to manipulate others in defense of the arbitrary choices of its users
  • examining the current condition of secular moral and political discourse. MacIntyre finds contending parties defending their decisions by appealing to abstract moral principles, but he finds their appeals eclectic, inconsistent, and incoherent.
  • The secular moral philosophers of the eighteenth and nineteenth centuries shared strong and extensive agreements about the content of morality (AV, p. 51) and believed that their moral philosophy could justify the demands of their morality rationally, free from religious authority.
  • MacIntyre traces the lineage of the culture of emotivism to the secularized Protestant cultures of northern Europe
  • Modern moral philosophy had thus set for itself an incoherent goal. It was to vindicate both the moral autonomy of the individual and the objectivity, necessity, and categorical character of the rules of morality
  • MacIntyre turns to an apparent alternative, the pragmatic expertise of professional managers. Managers are expected to appeal to the facts to make their decisions on the objective basis of effectiveness, and their authority to do this is based on their knowledge of the social sciences
  • An examination of the social sciences reveals, however, that many of the facts to which managers appeal depend on sociological theories that lack scientific status. Thus, the predictions and demands of bureaucratic managers are no less liable to ideological manipulation than the determinations of modern moral philosophers.
  • Modern moral philosophy separates moral reasoning about duties and obligations from practical reasoning about ends and practical deliberation about the means to one’s ends, and in doing so it separates morality from practice.
  • Many Europeans also lost the practical justifications for their moral norms as they approached modernity; for these Europeans, claiming that certain practices are “immoral,” and invoking Kant’s categorical imperative or Mill’s principle of utility to explain why those practices are immoral, seems no more adequate than the Polynesian appeal to taboo.
  • MacIntyre sifts these definitions and then gives his own definition of virtue, as excellence in human agency, in terms of practices, whole human lives, and traditions in chapters 14 and 15 of AV.
  • In the most often quoted sentence of AV, MacIntyre defines a practice as (1) a complex social activity that (2) enables participants to gain goods internal to the practice. (3) Participants achieve excellence in practices by gaining the internal goods. When participants achieve excellence, (4) the social understandings of excellence in the practice, of the goods of the practice, and of the possibility of achieving excellence in the practice “are systematically extended”
  • Practices, like chess, medicine, architecture, mechanical engineering, football, or politics, offer their practitioners a variety of goods both internal and external to these practices. The goods internal to practices include forms of understanding or physical abilities that can be acquired only by pursuing excellence in the associated practice
  • Goods external to practices include wealth, fame, prestige, and power; there are many ways to gain these external goods. They can be earned or purchased, either honestly or through deception; thus the pursuit of these external goods may conflict with the pursuit of the goods internal to practices.
  • An intelligent child is given the opportunity to win candy by learning to play chess. As long as the child plays chess only to win candy, he has every reason to cheat if by doing so he can win more candy. If the child begins to desire and pursue the goods internal to chess, however, cheating becomes irrational, because it is impossible to gain the goods internal to chess or any other practice except through an honest pursuit of excellence. Goods external to practices may nevertheless remain tempting to the practitioner.
  • Since MacIntyre finds social identity necessary for the individual, MacIntyre’s definition of the excellence or virtue of the human agent needs a social dimension:
  • These responsibilities also include debts incurred by the unjust actions of ones’ predecessors.
  • The enslavement and oppression of black Americans, the subjugation of Ireland, and the genocide of the Jews in Europe remained quite relevant to the responsibilities of citizens of the United States, England, and Germany in 1981, as they still do today.
  • Thus an American who said “I never owned any slaves,” “the Englishman who says ‘I never did any wrong to Ireland,’” or “the young German who believes that being born after 1945 means that what Nazis did to Jews has no moral relevance to his relationship to his Jewish contemporaries” all exhibit a kind of intellectual and moral failure.
  • “I am born with a past, and to cut myself off from that past in the individualist mode, is to deform my present relationships” (p. 221).&nbsp; For MacIntyre, there is no moral identity for the abstract individual; “The self has to find its moral identity in and through its membership in communities” (p. 221).

The Theory That Explains the Structure of the Internet - The Atlantic - 1 views

  • A paper posted online last month has reignited a debate about one of the oldest, most startling claims in the modern era of network science: the proposition that most complex networks in the real world—from the World Wide Web to interacting proteins in a cell—are “scale-free.” Roughly speaking, that means that a few of their nodes should have many more connections than others, following a mathematical formula called a power law, so that there’s no one scale that characterizes the network.
  • Purely random networks do not obey power laws, so when the early proponents of the scale-free paradigm started seeing power laws in real-world networks in the late 1990s, they viewed them as evidence of a universal organizing principle underlying the formation of these diverse networks. The architecture of scale-freeness, researchers argued, could provide insight into fundamental questions such as how likely a virus is to cause an epidemic, or how easily hackers can disable a network.
  • Amazingly simple and far-reaching natural laws govern the structure and evolution of all the complex networks that surround us,” wrote Barabási (who is now at Northeastern University in Boston) in Linked. He later added: “Uncovering and explaining these laws has been a fascinating roller-coaster ride during which we have learned more about our complex, interconnected world than was known in the last hundred years.”
  • ...5 more annotations...
  • “These results undermine the universality of scale-free networks and reveal that real-world networks exhibit a rich structural diversity that will likely require new ideas and mechanisms to explain,” wrote the study’s authors, Anna Broido and Aaron Clauset of the University of Colorado at Boulder.
  • Network scientists agree, by and large, that the paper’s analysis is statistically sound. But when it comes to interpreting its findings, the paper seems to be functioning like a Rorschach test, in which both proponents and critics of the scale-free paradigm see what they already believed to be true. Much of the discussion has played out in vigorous Twitter debates.
  • The scale-free paradigm in networks emerged at a historical moment when power laws had taken on an outsize role in statistical physics. In the 1960s and 1970s, they had played a key part in universal laws that underlie phase transitions in a wide range of physical systems, a finding that earned Kenneth Wilson the 1982 Nobel Prize in physics. Soon after, power laws formed the core of two other paradigms that swept across the statistical-physics world: fractals, and a theory about organization in nature called self-organized criticality.
  • From the beginning, though, the scale-free paradigm also attracted pushback. Critics pointed out that preferential attachment is far from the only mechanism that can give rise to power laws, and that networks with the same power law can have very different topologies. Some network scientists and domain experts cast doubt on the scale-freeness of specific networks such as power grids, metabolic networks, and the physical internet.
  • If you were to observe 1,000 falling objects instead of just a rock and a feather, Clauset says, a clear picture would emerge of how both gravity and air resistance work. But his and Broido’s analysis of nearly 1,000 networks has yielded no similar clarity. “It is reasonable to believe a fundamental phenomenon would require less customized detective work” than Barabási is calling for, Clauset wrote on Twitter.
