one of the leading modelers, Gabriela Gomes, suggested the entire area of research was being effectively blackballed out of fear it might encourage a relaxation of pandemic vigilance. “This is the very sad reason for the absence of more optimistic projections on the development of this pandemic in the scientific literature,” she wrote on Twitter. “Our analysis suggests that herd-immunity thresholds are being achieved despite strict social-distancing measures.”

Gomes suggested, herd immunity could happen with as little as one quarter of the population of a community exposed — or perhaps just 20 percent. “We just keep running the models, and it keeps coming back at less than 20 percent,” she told Hamblin. “It’s very striking.” Such findings, if they held up, would be very instructive, as Hamblin writes: “It would mean, for instance, that at 25 percent antibody prevalence, New York City could continue its careful reopening without fear of another major surge in cases.”

But for those hoping that 25 percent represents a true ceiling for pandemic spread in a given community, well, it almost certainly does not, considering that recent serological surveys have shown that perhaps 93 percent of the population of Iquitos, Peru, has contracted the disease; as have more than half of those living in Indian slums; and as many as 68 percent in particular neighborhoods of New York City

overshoot of that scale would seem unlikely if the “true” threshold were as low as 20 or 25 percent.

But, of course, that threshold may not be the same in all places, across all populations, and is surely affected, to some degree, by the social behavior taken to protect against the spread of the disease.

we probably err when we conceive of group immunity in simplistically binary terms. While herd immunity is a technical term referring to a particular threshold at which point the disease can no longer spread, some amount of community protection against that spread begins almost as soon as the first people are exposed, with each case reducing the number of unexposed and vulnerable potential cases in the community by one

you would not expect a disease to spread in a purely exponential way until the point of herd immunity, at which time the spread would suddenly stop. Instead, you would expect that growth to slow as more people in the community were exposed to the disease, with most of them emerging relatively quickly with some immune response. Add to that the effects of even modest, commonplace protections — intuitive social distancing, some amount of mask-wearing — and you could expect to get an infection curve that tapers off well shy of 60 percent exposure.

Looking at the data, we see that transmissions in many severely impacted states began to slow down in July, despite limited interventions. This is especially notable in states like Arizona, Florida, and Texas. While we believe that changes in human behavior and changes in policy (such as mask mandates and closing of bars/nightclubs) certainly contributed to the decrease in transmission, it seems unlikely that these were the primary drivers behind the decrease. We believe that many regions obtained a certain degree of temporary herd immunity after reaching 10-35 percent prevalence under the current conditions. We call this 10-35 percent threshold the effective herd immunity threshold.

Indeed, that is more or less what was recently found by Youyang Gu, to date the best modeler of pandemic spread in the U.S

he cautioned again that he did not mean to imply that the natural herd-immunity level was as low as 10 percent, or even 35 percent. Instead, he suggested it was a plateau determined in part by better collective understanding of the disease and what precautions to take

Gu estimates national prevalence as just below 20 percent (i.e., right in the middle of his range of effective herd immunity), it still counts, I think, as encouraging — even if people in hard-hit communities won’t truly breathe a sigh of relief until vaccines arrive.

If you can get real protection starting at 35 percent, it means that even a mediocre vaccine, administered much more haphazardly to a population with some meaningful share of vaccination skeptics, could still achieve community protection pretty quickly. And that is really significant — making both the total lack of national coordination on rollout and the likely “vaccine wars” much less consequential.

At least 20 percent of the public, and perhaps 50 percent, had some preexisting, cross-protective T-cell response to SARS-CoV-2, according to one much-discussed recent paper. An earlier paper had put the figure at between 40 and 60 percent. And a third had found an even higher prevalence: 81 percent.

The T-cell story is similarly encouraging in its big-picture implications without being necessarily paradigm-changing

These numbers suggest their own heterogeneity — that different populations, with different demographics, would likely exhibit different levels of cross-reactive T-cell immune response

The most optimistic interpretation of the data was given to me by Francois Balloux, a somewhat contrarian disease geneticist and the director of the University College of London’s Genetics Institute

According to him, a cross-reactive T-cell response wouldn’t prevent infection, but would probably mean a faster immune response, a shorter period of infection, and a “massively” reduced risk of severe illness — meaning, he guessed, that somewhere between a third and three-quarters of the population carried into the epidemic significant protection against its scariest outcomes

the distribution of this T-cell response could explain at least some, and perhaps quite a lot, of COVID-19’s age skew when it comes to disease severity and mortality, since the young are the most exposed to other coronaviruses, and the protection tapers as you get older and spend less time in environments, like schools, where these viruses spread so promiscuously.

Balloux told me he believed it was also possible that the heterogeneous distribution of T-cell protection also explains some amount of the apparent decline in disease severity over time within countries on different pandemic timelines — a phenomenon that is more conventionally attributed to infection spreading more among the young, better treatment, and more effective protection of the most vulnerable (especially the old).

Going back to Youyang Gu’s analysis, what he calls the “implied infection fatality rate” — essentially an estimated ratio based on his modeling of untested cases — has fallen for the country as a whole from about one percent in March to about 0.8 percent in mid-April, 0.6 percent in May, and down to about 0.25 percent today.

even as we have seemed to reach a second peak of coronavirus deaths, the rate of death from COVID-19 infection has continued to decline — total deaths have gone up, but much less than the number of cases

In other words, at the population level, the lethality of the disease in America has fallen by about three-quarters since its peak. This is, despite everything that is genuinely horrible about the pandemic and the American response to it, rather fantastic.

there may be some possible “mortality displacement,” whereby the most severe cases show up first, in the most susceptible people, leaving behind a relatively protected population whose experience overall would be more mild, and that T-cell response may play a significant role in determining that susceptibility.

That, again, is Balloux’s interpretation — the most expansive assessment of the T-cell data offered to me

The most conservative assessment came from Sarah Fortune, the chair of Harvard’s Department of Immunology

Fortune cautioned not to assume that cross-protection was playing a significant role in determining severity of illness in a given patient. Those with such a T-cell response, she told me, would likely see a faster onset of robust response, yes, but that may or may not yield a shorter period of infection and viral shedding

Most of the scientists, doctors, epidemiologists, and immunologists I spoke to fell between those two poles, suggesting the T-cell cross-immunity findings were significant without necessarily being determinative — that they may help explain some of the shape of pandemic spread through particular populations, but only some of the dynamics of that spread.

he told me he believed, in the absence of that data, that T-cell cross-immunity from exposure to previous coronaviruses “might explain different disease severity in different people,” and “could certainly be part of the explanation for the age skew, especially for why the very young fare so well.”

the headline finding was quite clear and explicitly stated: that preexisting T-cell response came primarily via the variety of T-cells called CD4 T-cells, and that this dynamic was consistent with the hypothesis that the mechanism was inherited from previous exposure to a few different “common cold” coronaviruses

“This potential preexisting cross-reactive T-cell immunity to SARS-CoV-2 has broad implications,” the authors wrote, “as it could explain aspects of differential COVID-19 clinical outcomes, influence epidemiological models of herd immunity, or affect the performance of COVID-19 candidate vaccines.”

“This is at present highly speculative,” they cautioned.

U.S. Border Patrol agents responding to a rescue call found a mother and two children, all three unconscious, on an island in the river that separates the United States from Mexico.

The agents were able to resuscitate the mother and the younger child, a 3-year-old boy.

The rescued mother was Guatemalan; her children were both Mexican nationals, the statement said.

Since 2004, about 3,400 migrants have perished in southern Arizona.

Monthly apprehensions had plummeted to 16,182 in April 2020 as the pandemic prompted former President Donald J. Trump to invoke a public-health emergency to seal the southwestern border to all but essential travel.

Specificity and restrictions create freedom and nourish creativity. Add them to your arsenal of tools as you become an uber productive and efficient creator.

While the plan offers a short-term solution for protecting those most vulnerable to violence, it does not address the magnitude of the migration. In the first six months of the current fiscal year, the U.S. border patrol apprehended 120,700 people from the Northern Triangle countries attempting to enter the U.S. Some of those who cross the border will apply for asylum, but the majority will be sent back to their countries of origin and the violence they were fleeing.

Costa Rica is a major destination for migrants and refugees in the region, and immigrants account for 9 percent of the country’s population of 4.8 million. Like the United States, Costa Rica has seen a dramatic increase in arrivals of refugees from Northern Triangle countries, particularly El Salvador, since 2012

Over the past 10 years, the country has increased restrictions on immigration, hoping to discourage low-income economic migrants from Nicaragua from entering. These restrictions echo the national security logic of U.S. policies.

It neither addresses the underlying conditions of violence that refugees seek to escape nor strengthens regional governments’ abilities to deal with the arrival of these vulnerable populations.

Psychologists say that starting when they are infants and young children, people become attuned to the key facial features and characteristics of the those around them. Whites often become accustomed to focusing on differences in hair color and eye color. African-Americans grow more familiar with subtle shadings of skin color.

Minorities tend to be better at cross-race identification than whites, Professor Meissner said, in part because they have more extensive and meaningful exposure to whites than the other way around.

Professor Malpass, who has trained police officers and border patrol agents, urges law enforcement agencies to make sure black or Hispanic officers are involved when creating lineups of black and Hispanic suspects. And he warns of the dangers of relying on cross-racial identifications from eyewitnesses, who can be fallible.

“I don’t think we should be offended,” he said. “This is really an ability issue.

“Rabin: The Last Day.” Agence France-Presse said the movie, by the renowned Israeli director Amos Gitai, is about “the incitement campaign before the 1995 assassination of Prime Minister Yitzhak Rabin” and “revisits a form of Jewish radicalism that still poses major risks.”

Sure, the official investigating commission focused on the breakdowns in Rabin’s security detail, but, Gitai added, “They didn’t investigate what were the underlying forces that wanted to kill Rabin. His murder came at the end of a hate campaign led by hallucinating rabbis, settlers who were against the withdrawal from territories and the parliamentary right, led by the Likud (party), already then headed by Benjamin Netanyahu, who wanted to destabilize Rabin’s Labor government.”

I hope a lot of Americans see this film — for the warning it offers to those who ignore or rationalize the divisive, bigoted campaigns of Donald Trump and Ben Carson and how they’re dragging their whole party across civic redlines, with candidates saying, rationalizing or ignoring more and more crazy, ill-informed stuff each week.

Last week another redline was crossed. At a Trump town hall event, the first questioner began: “We got a problem in this country. It’s called Muslims. We know our current president is one. We know he’s not even an American. But anyway. We have training camps brewing where they want to kill us. That’s my question. When can we get rid of them?”Trump responded: “A lot of people are saying that bad things are happening out there. We’re going to be looking into that and plenty of other things.”

Trump could have let the man ask his question and then correct his racist nonsense, without blocking his free speech, which is exactly what McCain did in a similar situation

Instead he tweeted: “Christians need support in our country (and around the world), their religious liberty is at stake! Obama has been horrible, I will be great.”

And then, like clockwork, Ben Carson saw Trump blurring another civic redline and leapfrogged him. Carson stated, “I would not advocate that we put a Muslim in charge of this nation.”

So a whole faith community gets delegitimized and another opportunity for someone to courageously stand up for what’s decent is squandered. But it will play well with certain voters. And that is all that matters — until something really bad happens. And then, all of it — the words, tweets, signs and boasts — will be footage for another documentary that ends badly.

Perhaps some aspects of consciousness arise from these meta-networks -- and to investigate the proposition, the researchers analysed fMRI scans of 15 people after being injected with psilocybin, the active ingredient in magic mushrooms, and compared them to scans of their brain activity after receiving a placebo.

"One possible by-product of this greater communication across the whole brain is the phenomenon of synaesthesia" -- the experience, common during psychedelic experiences, of sensory mix-up: tasting colours, feeling sounds, seeing smells, and so on.

A truer way of visualising it, he said, would be in three dimensions, with connections between networks forming a sponge-like topography.

"The big question in neuroscience is where consciousness comes from," Petri said. For now, he said, "We don't know."

Peterson deserves a full, appropriately complex accounting of his best and worst arguments; I intend to give him one soon. For now, I can only tell you how the Peterson phenomenon manifested one night in Aspen

“For the first time in human history the spoken word has the same reach as the written word, and there are no barriers to entry. That’s a Gutenberg revolution,” he said. “That’s a big deal. This is a game changer. The podcast world is also a Gutenberg moment but it’s even more extensive. The problem with books is that you can’t do anything else while you’re reading. But if you’re listening to a podcast you can be driving a tractor or a long haul truck or doing the dishes. So podcasts free up two hours a day for people to engage in educational activity they otherwise wouldn’t be able to engage in. That’s one-eighth of people’s lives. You’re handing people a lot of time back to engage in high-level intellectual education.

that technological revolution has revealed something good that we didn’t know before: “The narrow bandwidth of TV has made us think that we are stupider than we are. And people have a real hunger for deep intellectual dialogue.”

I’ve known for years that the university underserved the community, because we assumed that university education is for 18- to 22-year-olds, which is a proposition that’s so absurd it is absolutely mind-boggling that anyone ever conceptualized it. Why wouldn’t you take university courses throughout your entire life? What, you stop searching for wisdom when you’re 22? I don’t think so. You don’t even start until you’re like in your mid 20s. So I knew universities were underserving the broader community a long time ago. But there wasn’t a mechanism whereby that could be rectified.

Universities are beyond forgiveness, he argued, because due to the growing ranks of administrators, there’s been a radical increase in tuition. “Unsuspecting students are given free access to student loans that will cripple them through their 30s and their 40s, and the universities are enticing them to extend their carefree adolescence for a four year period at the cost of mortgaging their future in a deal that does not allow for escape through bankruptcy,” he complained. “So it’s essentially a form of indentured servitude. There’s no excuse for that … That cripples the economy because the students become overlaid with debt that they’ll never pay off at the time when they should be at the peak of their ability to take entrepreneurial risks. That’s absolutely appalling.”

A critique I frequently hear from Peterson’s critics is that everything he says is either obvious or wrong. I think that critique fails insofar as I sometimes see some critics calling one of his statements obvious even as others insist it is obviously wrong.

a reliable difference among men and women cross-culturally is that men are more aggressive than women. Now what's the evidence for that? Here's one piece of evidence: There are 10 times as many men in prison. Now is that a sociocultural construct? It's like, no, it's not a sociocultural construct. Okay?

Here's another piece of data. Women try to commit suicide more than men by a lot, and that's because women are more prone to depression and anxiety than men are. And there are reasons for that, and that's cross-cultural as well. Now men are way more likely to actually commit suicide. Why? Because they're more aggressive so they use lethal means. So now the question is how much more aggressive are men than women? The answer is not very much. So the claim that men and women are more the same than different is actually true. This is where you have to know something about statistics to understand the way the world works, instead of just applying your a priori ideological presuppositions to things that are too complex to fit in that rubric.

So if you draw two people out of a crowd, one man and one woman, and you had to lay a bet on who was more aggressive, and you bet on the woman, you'd win 40 percent of the time. That's quite a lot. It isn't 50 percent of the time which would be no differences. But it’s a lot. There are lots of women who are more aggressive than lots of men. So the curves overlap a lot. There's way more similarity than difference. And this is along the dimension where there's the most difference. But here's the problem. You can take small differences at the average of a distribution. Then the distributions move off to the side. And then all the action is at the tail. So here's the situation. You don't care about how aggressive the average person is. It's not that relevant. What people care about is who is the most aggressive person out of 100, because that's the person you'd better watch out for.

Whenever I'm interviewed by journalists who have the scent of blood in their nose, let's say, they're very willing and able to characterize the situation I find myself in as political. But that's because they can't see the world in any other manner. The political is a tiny fraction of the world. And what I'm doing isn't political. It's psychological or theological. The political element is peripheral. And if people come to the live lectures, let's say, that's absolutely self-evident

In a New York Times article titled, “Jordan Peterson, Custodian of the Patriarchy,” the writer Nellie Bowles quoted her subject as follows:

Violent attacks are what happens when men do not have partners, Mr. Peterson says, and society needs to work to make sure those men are married. “He was angry at God because women were rejecting him,” Mr. Peterson says of the Toronto killer. “The cure for that is enforced monogamy. That’s actually why monogamy emerges.” Mr. Peterson does not pause when he says this. Enforced monogamy is, to him, simply a rational solution. Otherwise women will all only go for the most high-status men, he explains, and that couldn’t make either gender happy in the end.

Ever since, some Peterson critics have claimed that Peterson wants to force women to have sex with male incels, or something similarly dystopian.

...it's an anthropological truism generated primarily through scholars on the left, just so everybody is clear about it, that societies that use monogamy as a social norm, which by the way is virtually every human society that ever existed, do that in an attempt to control the aggression that goes along with polygamy. It's like ‘Oh my God, how contentious can you get.’ Well, how many of you are in monogamous relationships? A majority. How is that enforced?...

If everyone you talk to is boring it’s not them! And so if you're rejected by the opposite sex, if you’re heterosexual, then you're wrong, they're not wrong, and you've got some work to do, man. You've got some difficult work to do. And there isn't anything I've been telling young men that's clearer than that … What I've been telling people is take the responsibility for failure onto yourself. That's a hint that you've got work to do. It could also be a hint that you're young and useless and why the hell would anybody have anything to do with you because you don't have anything to offer. And that's rectifiable. Maturity helps to rectify that.

And what's the gender? Men. Because if you go two standard deviations out from the mean on two curves that overlap but are disjointed, then you derive an overwhelming preponderance of the overrepresented group. That's why men are about 10 times more likely to be in prison.  

Weiss: You are often characterized, at least in the mainstream press, as being transphobic. If you had a student come to you and say, I was born female, I now identify as male, I want you to call me by male pronouns. Would you say yes to that?

Peterson: Well, it would depend on the student and the context and why I thought they were asking me and what I believe their demand actually characterized, and all of that. Because that can be done in a way that is genuine and acceptable, and a way that is manipulative and unacceptable. And if it was genuine and acceptable then I would have no problem with it. And if it was manipulative and unacceptable then not a chance. And you might think, ‘Well, who am I to judge?’ Well, first of all, I am a clinical psychologist, I've talked to people for about 25,000 hours. And I'm responsible for judging how I am going to use my words. I'd judge the same way I judge all my interactions with people, which is to the best of my ability, and characterized by all the errors that I'm prone to. I'm not saying that my judgment would be unerring. I live with the consequences and I'm willing to accept the responsibility.

But also to be clear about this, it never happened––I never refused to call anyone by anything they had asked me to call them by, although that's been reported multiple times. It's a complete falsehood. And it had nothing to do with the transgender issue as far as I'm concerned.

type one and type two error problem

note what his avowed position is: that he has never refused to call a transgender person by their preferred pronoun, that he has done so many times, that he would always try to err on the side of believing a request to be earnest, and that he reserves the right to decline a request he believes to be in bad faith. Whether one finds that to be reasonable or needlessly difficult, it seems irresponsible to tell trans people that a prominent intellectual hates them or is deeply antagonistic to them when the only seeming conflict is utterly hypothetical and ostensibly not even directed against people that Peterson believes to be trans, but only against people whom he does not believe to be trans

Sartre listened to his problem and said simply, ‘You are free, therefore choose — that is to say, invent.’ No signs are vouchsafed in this world, he said. None of the old authorities can relieve you of the burden of freedom. You can weigh up moral or practical considerations as carefully as you like, but ultimately you must take the plunge and do something, and it’s up to you what that something is.

Even if the situation is unbearable — perhaps you are facing execution, or sitting in a Gestapo prison, or about to fall off a cliff — you are still free to decide what to make of it in mind and deed. Starting from where you are now, you choose. And in choosing, you also choose who you will be.

The war had made people realise that they and their fellow humans were capable of departing entirely from civilised norms; no wonder the idea of a fixed human nature seemed questionable.

If this sounds difficult and unnerving, it’s because it is. Sartre does not deny that the need to keep making decisions brings constant anxiety. He heightens this anxiety by pointing out that what you do really matters. You should make your choices as though you were choosing on behalf of the whole of humanity, taking the entire burden of responsibility for how the human race behaves. If you avoid this responsibility by fooling yourself that you are the victim of circumstance or of someone else’s bad advice, you are failing to meet the demands of human life and choosing a fake existence, cut off from your own ‘authenticity’.

Along with the terrifying side of this comes a great promise: Sartre’s existentialism implies that it is possible to be authentic and free, as long as you keep up the effort.

almost all agreed that it was, as an article in Les nouvelles littéraires phrased it, a ‘sickening mixture of philosophic pretentiousness, equivocal dreams, physiological technicalities, morbid tastes and hesitant eroticism … an introspective embryo that one would take distinct pleasure in crushing’.

he offered a philosophy designed for a species that had just scared the hell out of itself, but that finally felt ready to grow up and take responsibility.

In this rebellious world, just as with the Parisian bohemians and Dadaists in earlier generations, everything that was dangerous and provocative was good, and everything that was nice or bourgeois was bad.

Such interweaving of ideas and life had a long pedigree, although the existentialists gave it a new twist. Stoic and Epicurean thinkers in the classical world had practised philosophy as a means of living well, rather than of seeking knowledge or wisdom for their own sake. By reflecting on life’s vagaries in philosophical ways, they believed they could become more resilient, more able to rise above circumstances, and better equipped to manage grief, fear, anger, disappointment or anxiety.

In the tradition they passed on, philosophy is neither a pure intellectual pursuit nor a collection of cheap self-help tricks, but a discipline for flourishing and living a fully human, responsible life.

For Kierkegaard, Descartes had things back to front. In his own view, human existence comes first: it is the starting point for everything we do, not the result of a logical deduction. My existence is active: I live it and choose it, and this precedes any statement I can make about myself.

Studying our own moral genealogy cannot help us to escape or transcend ourselves. But it can enable us to see our illusions more clearly and lead a more vital, assertive existence.

What was needed, he felt, was not high moral or theological ideals, but a deeply critical form of cultural history or ‘genealogy’ that would uncover the reasons why we humans are as we are, and how we came to be that way. For him, all philosophy could even be redefined as a form of psychology, or history.

For those oppressed on grounds of race or class, or for those fighting against colonialism, existentialism offered a change of perspective — literally, as Sartre proposed that all situations be judged according to how they appeared in the eyes of those most oppressed, or those whose suffering was greatest.

She observed that we need not expect moral philosophers to ‘live by’ their ideas in a simplistic way, as if they were following a set of rules. But we can expect them to show how their ideas are lived in. We should be able to look in through the windows of a philosophy, as it were, and see how people occupy it, how they move about and how they conduct themselves.

the existentialists inhabited their historical and personal world, as they inhabited their ideas. This notion of ‘inhabited philosophy’ is one I’ve borrowed from the English philosopher and novelist Iris Murdoch, who wrote the first full-length book on Sartre and was an early adopter of existentialism

What is existentialism anyway?

An existentialist who is also phenomenological provides no easy rules for dealing with this condition, but instead concentrates on describing lived experience as it presents itself. — By describing experience well, he or she hopes to understand this existence and awaken us to ways of living more authentic lives.

Existentialists concern themselves with individual, concrete human existence. — They consider human existence different from the kind of being other things have. Other entities are what they are, but as a human I am whatever I choose to make of myself at every moment. I am free — — and therefore I’m responsible for everything I do, a dizzying fact which causes — an anxiety inseparable from human existence itself.

On the other hand, I am only free within situations, which can include factors in my own biology and psychology as well as physical, historical and social variables of the world into which I have been thrown. — Despite the limitations, I always want more: I am passionately involved in personal projects of all kinds. — Human existence is thus ambiguous: at once boxed in by borders and yet transcendent and exhilarating. —

The first part of this is straightforward: a phenomenologist’s job is to describe. This is the activity that Husserl kept reminding his students to do. It meant stripping away distractions, habits, clichés of thought, presumptions and received ideas, in order to return our attention to what he called the ‘things themselves’. We must fix our beady gaze on them and capture them exactly as they appear, rather than as we think they are supposed to be.

Husserl therefore says that, to phenomenologically describe a cup of coffee, I should set aside both the abstract suppositions and any intrusive emotional associations. Then I can concentrate on the dark, fragrant, rich phenomenon in front of me now. This ‘setting aside’ or ‘bracketing out’ of speculative add-ons Husserl called epoché — a term borrowed from the ancient Sceptics,

The point about rigour is crucial; it brings us back to the first half of the command to describe phenomena. A phenomenologist cannot get away with listening to a piece of music and saying, ‘How lovely!’ He or she must ask: is it plaintive? is it dignified? is it colossal and sublime? The point is to keep coming back to the ‘things themselves’ — phenomena stripped of their conceptual baggage — so as to bail out weak or extraneous material and get to the heart of the experience.

Husserlian ‘bracketing out’ or epoché allows the phenomenologist to temporarily ignore the question ‘But is it real?’, in order to ask how a person experiences his or her world. Phenomenology gives a formal mode of access to human experience. It lets philosophers talk about life more or less as non-philosophers do, while still being able to tell themselves they are being methodical and rigorous.

Besides claiming to transform the way we think about reality, phenomenologists promised to change how we think about ourselves. They believed that we should not try to find out what the human mind is, as if it were some kind of substance. Instead, we should consider what it does, and how it grasps its experiences.

For Brentano, this reaching towards objects is what our minds do all the time. Our thoughts are invariably of or about something, he wrote: in love, something is loved, in hatred, something is hated, in judgement, something is affirmed or denied. Even when I imagine an object that isn’t there, my mental structure is still one of ‘about-ness’ or ‘of-ness’.

Except in deepest sleep, my mind is always engaged in this aboutness: it has ‘intentionality’. Having taken the germ of this from Brentano, Husserl made it central to his whole philosophy.

Husserl saw in the idea of intentionality a way to sidestep two great unsolved puzzles of philosophical history: the question of what objects ‘really’ are, and the question of what the mind ‘really’ is. By doing the epoché and bracketing out all consideration of reality from both topics, one is freed to concentrate on the relationship in the middle. One can apply one’s descriptive energies to the endless dance of intentionality that takes place in our lives: the whirl of our minds as they seize their intended phenomena one after the other and whisk them around the floor,

Understood in this way, the mind hardly is anything at all: it is its aboutness. This makes the human mind (and possibly some animal minds) different from any other naturally occurring entity. Nothing else can be as thoroughly about or of things as the mind is:

Some Eastern meditation techniques aim to still this scurrying creature, but the extreme difficulty of this shows how unnatural it is to be mentally inert. Left to itself, the mind reaches out in all directions as long as it is awake — and even carries on doing it in the dreaming phase of its sleep.

a mind that is experiencing nothing, imagining nothing, or speculating about nothing can hardly be said to be a mind at all.

Three simple ideas — description, phenomenon, intentionality — provided enough inspiration to keep roomfuls of Husserlian assistants busy in Freiburg for decades. With all of human existence awaiting their attention, how could they ever run out of things to do?

For Sartre, this gives the mind an immense freedom. If we are nothing but what we think about, then no predefined ‘inner nature’ can hold us back. We are protean.

way of this interpretation. Real, not real; inside, outside; what difference did it make? Reflecting on this, Husserl began turning his phenomenology into a branch of ‘idealism’ — the philosophical tradition which denied external reality and defined everything as a kind of private hallucination.

For Sartre, if we try to shut ourselves up inside our own minds, ‘in a nice warm room with the shutters closed’, we cease to exist. We have no cosy home: being out on the dusty road is the very definition of what we are.

One might think that, if Heidegger had anything worth saying, he could have communicated it in ordinary language. The fact is that he does not want to be ordinary, and he may not even want to communicate in the usual sense. He wants to make the familiar obscure, and to vex us. George Steiner thought that Heidegger’s purpose was less to be understood than to be experienced through a ‘felt strangeness’.

He takes Dasein in its most ordinary moments, then talks about it in the most innovative way he can. For Heidegger, Dasein’s everyday Being is right here: it is Being-in-the-world, or In-der-Welt-sein. The main feature of Dasein’s everyday Being-in-the-world right here is that it is usually busy doing something.

Thus, for Heidegger, all Being-in-the-world is also a ‘Being-with’ or Mitsein. We cohabit with others in a ‘with-world’, or Mitwelt. The old philosophical problem of how we prove the existence of other minds has now vanished. Dasein swims in the with-world long before it wonders about other minds.

Sometimes the best-educated people were those least inclined to take the Nazis seriously, dismissing them as too absurd to last. Karl Jaspers was one of those who made this mistake, as he later recalled, and Beauvoir observed similar dismissive attitudes among the French students in Berlin.

In any case, most of those who disagreed with Hitler’s ideology soon learned to keep their view to themselves. If a Nazi parade passed on the street, they would either slip out of view or give the obligatory salute like everyone else, telling themselves that the gesture meant nothing if they did not believe in it. As the psychologist Bruno Bettelheim later wrote of this period, few people will risk their life for such a small thing as raising an arm — yet that is how one’s powers of resistance are eroded away, and eventually one’s responsibility and integrity go with them.

for Arendt, if you do not respond adequately when the times demand it, you show a lack of imagination and attention that is as dangerous as deliberately committing an abuse. It amounts to disobeying the one command she had absorbed from Heidegger in those Marburg days: Think!

‘Everything takes place under a kind of anaesthesia. Objectively dreadful events produce a thin, puny emotional response. Murders are committed like schoolboy pranks. Humiliation and moral decay are accepted like minor incidents.’ Haffner thought modernity itself was partly to blame: people had become yoked to their habits and to mass media, forgetting to stop and think, or to disrupt their routines long enough to question what was going on.

Heidegger’s former lover and student Hannah Arendt would argue, in her 1951 study The Origins of Totalitarianism, that totalitarian movements thrived at least partly because of this fragmentation in modern lives, which made people more vulnerable to being swept away by demagogues. Elsewhere, she coined the phrase ‘the banality of evil’ to describe the most extreme failures of personal moral awareness.

His communicative ideal fed into a whole theory of history: he traced all civilisation to an ‘Axial Period’ in the fifth century BC, during which philosophy and culture exploded simultaneously in Europe, the Middle East and Asia, as though a great bubble of minds had erupted from the earth’s surface. ‘True philosophy needs communion to come into existence,’ he wrote, and added, ‘Uncommunicativeness in a philosopher is virtually a criterion of the untruth of his thinking.’

The idea of being called to authenticity became a major theme in later existentialism, the call being interpreted as saying something like ‘Be yourself!’, as opposed to being phony. For Heidegger, the call is more fundamental than that. It is a call to take up a self that you didn’t know you had: to wake up to your Being. Moreover, it is a call to action. It requires you to do something: to take a decision of some sort.

Being and Time contained at least one big idea that should have been of use in resisting totalitarianism. Dasein, Heidegger wrote there, tends to fall under the sway of something called das Man or ‘the they’ — an impersonal entity that robs us of the freedom to think for ourselves. To live authentically requires resisting or outwitting this influence, but this is not easy because das Man is so nebulous. Man in German does not mean ‘man’ as in English (that’s der Mann), but a neutral abstraction, something like ‘one’ in the English phrase ‘one doesn’t do that’,

for Heidegger, das Man is me. It is everywhere and nowhere; it is nothing definite, but each of us is it. As with Being, it is so ubiquitous that it is difficult to see. If I am not careful, however, das Man takes over the important decisions that should be my own. It drains away my responsibility or ‘answerability’. As Arendt might put it, we slip into banality, failing to think.

Jaspers focused on what he called Grenzsituationen — border situations, or limit situations. These are the moments when one finds oneself constrained or boxed in by what is happening, but at the same time pushed by these events towards the limits or outer edge of normal experience. For example, you might have to make a life-or-death choice, or something might remind you suddenly of your mortality,

Jaspers’ interest in border situations probably had much to do with his own early confrontation with mortality. From childhood, he had suffered from a heart condition so severe that he always expected to die at any moment. He also had emphysema, which forced him to speak slowly, taking long pauses to catch his breath. Both illnesses meant that he had to budget his energies with care in order to get his work done without endangering his life.

If I am to resist das Man, I must become answerable to the call of my ‘voice of conscience’. This call does not come from God, as a traditional Christian definition of the voice of conscience might suppose. It comes from a truly existentialist source: my own authentic self. Alas, this voice is one I do not recognise and may not hear, because it is not the voice of my habitual ‘they-self’. It is an alien or uncanny version of my usual voice. I am familiar with my they-self, but not with my unalienated voice — so, in a weird twist, my real voice is the one that sounds strangest to me.

Marcel developed a strongly theological branch of existentialism. His faith distanced him from both Sartre and Heidegger, but he shared a sense of how history makes demands on individuals. In his essay ‘On the Ontological Mystery’, written in 1932 and published in the fateful year of 1933, Marcel wrote of the human tendency to become stuck in habits, received ideas, and a narrow-minded attachment to possessions and familiar scenes. Instead, he urged his readers to develop a capacity for remaining ‘available’ to situations as they arise. Similar ideas of disponibilité or availability had been explored by other writers,

Marcel made it his central existential imperative. He was aware of how rare and difficult it was. Most people fall into what he calls ‘crispation’: a tensed, encrusted shape in life — ‘as though each one of us secreted a kind of shell which gradually hardened and imprisoned him’.

Bettelheim later observed that, under Nazism, only a few people realised at once that life could not continue unaltered: these were the ones who got away quickly. Bettelheim himself was not among them. Caught in Austria when Hitler annexed it, he was sent first to Dachau and then to Buchenwald, but was then released in a mass amnesty to celebrate Hitler’s birthday in 1939 — an extraordinary reprieve, after which he left at once for America.

we are used to reading philosophy as offering a universal message for all times and places — or at least as aiming to do so. But Heidegger disliked the notion of universal truths or universal humanity, which he considered a fantasy. For him, Dasein is not defined by shared faculties of reason and understanding, as the Enlightenment philosophers thought. Still less is it defined by any kind of transcendent eternal soul, as in religious tradition. We do not exist on a higher, eternal plane at all. Dasein’s Being is local: it has a historical situation, and is constituted in time and place.

For Marcel, learning to stay open to reality in this way is the philosopher’s prime job. Everyone can do it, but the philosopher is the one who is called on above all to stay awake, so as to be the first to sound the alarm if something seems wrong.

Second, it also means understanding that we are historical beings, and grasping the demands our particular historical situation is making on us. In what Heidegger calls ‘anticipatory resoluteness’, Dasein discovers ‘that its uttermost possibility lies in giving itself up’. At that moment, through Being-towards-death and resoluteness in facing up to one’s time, one is freed from the they-self and attains one’s true, authentic self.

If we are temporal beings by our very nature, then authentic existence means accepting, first, that we are finite and mortal. We will die: this all-important realisation is what Heidegger calls authentic ‘Being-towards-Death’, and it is fundamental to his philosophy.

Hannah Arendt, instead, left early on: she had the benefit of a powerful warning. Just after the Nazi takeover, in spring 1933, she had been arrested while researching materials on anti-Semitism for the German Zionist Organisation at Berlin’s Prussian State Library. Her apartment was searched; both she and her mother were locked up briefly, then released. They fled, without stopping to arrange travel documents. They crossed to Czechoslovakia (then still safe) by a method that sounds almost too fabulous to be true: a sympathetic German family on the border had a house with its front door in Germany and its back door in Czechoslovakia. The family would invite people for dinner, then let them leave through the back door at night.

As Sartre argued in his 1943 review of The Stranger, basic phenomenological principles show that experience comes to us already charged with significance. A piano sonata is a melancholy evocation of longing. If I watch a soccer match, I see it as a soccer match, not as a meaningless scene in which a number of people run around taking turns to apply their lower limbs to a spherical object. If the latter is what I’m seeing, then I am not watching some more essential, truer version of soccer; I am failing to watch it properly as soccer at all.

Much as they liked Camus personally, neither Sartre nor Beauvoir accepted his vision of absurdity. For them, life is not absurd, even when viewed on a cosmic scale, and nothing can be gained by saying it is. Life for them is full of real meaning, although that meaning emerges differently for each of us.

For Sartre, we show bad faith whenever we portray ourselves as passive creations of our race, class, job, history, nation, family, heredity, childhood influences, events, or even hidden drives in our subconscious which we claim are out of our control. It is not that such factors are unimportant: class and race, in particular, he acknowledged as powerful forces in people’s lives, and Simone de Beauvoir would soon add gender to that list.

Sartre takes his argument to an extreme point by asserting that even war, imprisonment or the prospect of imminent death cannot take away my existential freedom. They form part of my ‘situation’, and this may be an extreme and intolerable situation, but it still provides only a context for whatever I choose to do next. If I am about to die, I can decide how to face that death. Sartre here resurrects the ancient Stoic idea that I may not choose what happens to me, but I can choose what to make of it, spiritually speaking.

But the Stoics cultivated indifference in the face of terrible events, whereas Sartre thought we should remain passionately, even furiously engaged with what happens to us and with what we can achieve. We should not expect freedom to be anything less than fiendishly difficult.

Freedom does not mean entirely unconstrained movement, and it certainly does not mean acting randomly. We often mistake the very things that enable us to be free — context, meaning, facticity, situation, a general direction in our lives — for things that define us and take away our freedom. It is only with all of these that we can be free in a real sense.

Nor did he mean that privileged groups have the right to pontificate to the poor and downtrodden about the need to ‘take responsibility’ for themselves. That would be a grotesque misreading of Sartre’s point, since his sympathy in any encounter always lay with the more oppressed side. But for each of us — for me — to be in good faith means not making excuses for myself.

Camus’ novel gives us a deliberately understated vision of heroism and decisive action compared to those of Sartre and Beauvoir. One can only do so much. It can look like defeatism, but it shows a more realistic perception of what it takes to actually accomplish difficult tasks like liberating one’s country.

Camus just kept returning to his core principle: no torture, no killing — at least not with state approval. Beauvoir and Sartre believed they were taking a more subtle and more realistic view. If asked why a couple of innocuous philosophers had suddenly become so harsh, they would have said it was because the war had changed them in profound ways. It had shown them that one’s duties to humanity could be more complicated than they seemed. ‘The war really divided my life in two,’ Sartre said later.

Poets and artists ‘let things be’, but they also let things come out and show themselves. They help to ease things into ‘unconcealment’ (Unverborgenheit), which is Heidegger’s rendition of the Greek term alētheia, usually translated as ‘truth’. This is a deeper kind of truth than the mere correspondence of a statement to reality, as when we say ‘The cat is on the mat’ and point to a mat with a cat on it. Long before we can do this, both cat and mat must ‘stand forth out of concealedness’. They must un-hide themselves.

Heidegger does not use the word ‘consciousness’ here because — as with his earlier work — he is trying to make us think in a radically different way about ourselves. We are not to think of the mind as an empty cavern, or as a container filled with representations of things. We are not even supposed to think of it as firing off arrows of intentional ‘aboutness’, as in the earlier phenomenology of Brentano. Instead, Heidegger draws us into the depths of his Schwarzwald, and asks us to imagine a gap with sunlight filtering in. We remain in the forest, but we provide a relatively open spot where other beings can bask for a moment. If we did not do this, everything would remain in the thickets, hidden even to itself.

The astronomer Carl Sagan began his 1980 television series Cosmos by saying that human beings, though made of the same stuff as the stars, are conscious and are therefore ‘a way for the cosmos to know itself’. Merleau-Ponty similarly quoted his favourite painter Cézanne as saying, ‘The landscape thinks itself in me, and I am its consciousness.’ This is something like what Heidegger thinks humanity contributes to the earth. We are not made of spiritual nothingness; we are part of Being, but we also bring something unique with us. It is not much: a little open space, perhaps with a path and a bench like the one the young Heidegger used to sit on to do his homework. But through us, the miracle occurs.

Beauty aside, Heidegger’s late writing can also be troubling, with its increasingly mystical notion of what it is to be human. If one speaks of a human being mainly as an open space or a clearing, or a means of ‘letting beings be’ and dwelling poetically on the earth, then one doesn’t seem to be talking about any recognisable person. The old Dasein has become less human than ever. It is now a forestry feature.

Even today, Jaspers, the dedicated communicator, is far less widely read than Heidegger, who has influenced architects, social theorists, critics, psychologists, artists, film-makers, environmental activists, and innumerable students and enthusiasts — including the later deconstructionist and post-structuralist schools, which took their starting point from his late thinking. Having spent the late 1940s as an outsider and then been rehabilitated, Heidegger became the overwhelming presence in university philosophy all over the European continent from then on.

As Levinas reflected on this experience, it helped to lead him to a philosophy that was essentially ethical, rather than ontological like Heidegger’s. He developed his ideas from the work of Jewish theologian Martin Buber, whose I and Thou in 1923 had distinguished between my relationship with an impersonal ‘it’ or ‘them’, and the direct personal encounter I have with a ‘you’. Levinas took it further: when I encounter you, we normally meet face-to-face, and it is through your face that you, as another person, can make ethical demands on me. This is very different from Heidegger’s Mitsein or Being-with, which suggests a group of people standing alongside one another, shoulder to shoulder as if in solidarity — perhaps as a unified nation or Volk.

For Levinas, we literally face each other, one individual at a time, and that relationship becomes one of communication and moral expectation. We do not merge; we respond to one another. Instead of being co-opted into playing some role in my personal drama of authenticity, you look me in the eyes — and you remain Other. You remain you.

This relationship is more fundamental than the self, more fundamental than consciousness, more fundamental even than Being — and it brings an unavoidable ethical obligation. Ever since Husserl, phenomenologists and existentialists had being trying to stretch the definition of existence to incorporate our social lives and relationships. Levinas did more: he turned philosophy around entirely so that these relationships were the foundation of our existence, not an extension of it.

Her last work, The Need for Roots, argues, among other things, that none of us has rights, but each one of us has a near-infinite degree of duty and obligation to the other. Whatever the underlying cause of her death — and anorexia nervosa seems to have been involved — no one could deny that she lived out her philosophy with total commitment. Of all the lives touched on in this book, hers is surely the most profound and challenging application of Iris Murdoch’s notion that a philosophy can be ‘inhabited’.

Other thinkers took radical ethical turns during the war years. The most extreme was Simone Weil, who actually tried to live by the principle of putting other people’s ethical demands first. Having returned to France after her travels through Germany in 1932, she had worked in a factory so as to experience the degrading nature of such work for herself. When France fell in 1940, her family fled to Marseilles (against her protests), and later to the US and to Britain. Even in exile, Weil made extraordinary sacrifices. If there were people in the world who could not sleep in a bed, she would not do so either, so she slept on the floor.

The mystery tradition had roots in Kierkegaard’s ‘leap of faith’. It owed much to the other great nineteenth-century mystic of the impossible, Dostoevsky, and to older theological notions. But it also grew from the protracted trauma that was the first half of the twentieth century. Since 1914, and especially since 1939, people in Europe and elsewhere had come to the realisation that we cannot fully know or trust ourselves; that we have no excuses or explanations for what we do — and yet that we must ground our existence and relationships on something firm, because otherwise we cannot survive.

One striking link between these radical ethical thinkers, all on the fringes of our main story, is that they had religious faith. They also granted a special role to the notion of ‘mystery’ — that which cannot be known, calculated or understood, especially when it concerns our relationships with each other. Heidegger was different from them, since he rejected the religion he grew up with and had no real interest in ethics — probably as a consequence of his having no real interest in the human.

Meanwhile, the Christian existentialist Gabriel Marcel was also still arguing, as he had since the 1930s, that ethics trumps everything else in philosophy and that our duty to each other is so great as to play the role of a transcendent ‘mystery’. He too had been led to this position partly by a wartime experience: during the First World War he had worked for the Red Cross’ Information Service, with the unenviable job of answering relatives’ inquiries about missing soldiers. Whenever news came, he passed it on, and usually it was not good. As Marcel later said, this task permanently inoculated him against warmongering rhetoric of any kind, and it made him aware of the power of what is unknown in our lives.

As the play’s much-quoted and frequently misunderstood final line has it: ‘Hell is other people.’ Sartre later explained that he did not mean to say that other people were hellish in general. He meant that after death we become frozen in their view, unable any longer to fend off their interpretation. In life, we can still do something to manage the impression we make; in death, this freedom goes and we are left entombed in other’s people’s memories and perceptions.

We have to do two near-impossible things at once: understand ourselves as limited by circumstances, and yet continue to pursue our projects as though we are truly in control. In Beauvoir’s view, existentialism is the philosophy that best enables us to do this, because it concerns itself so deeply with both freedom and contingency. It acknowledges the radical and terrifying scope of our freedom in life, but also the concrete influences that other philosophies tend to ignore: history, the body, social relationships and the environment.

The aspects of our existence that limit us, Merleau-Ponty says, are the very same ones that bind us to the world and give us scope for action and perception. They make us what we are. Sartre acknowledged the need for this trade-off, but he found it more painful to accept. Everything in him longed to be free of bonds, of impediments and limitations

Of course we have to learn this skill of interpreting and anticipating the world, and this happens in early childhood, which is why Merleau-Ponty thought child psychology was essential to philosophy. This is an extraordinary insight. Apart from Rousseau, very few philosophers before him had taken childhood seriously; most wrote as though all human experience were that of a fully conscious, rational, verbal adult who has been dropped into this world from the sky — perhaps by a stork.

For Merleau-Ponty, we cannot understand our experience if we don’t think of ourselves in part as overgrown babies. We fall for optical illusions because we once learned to see the world in terms of shapes, objects and things relevant to our own interests. Our first perceptions came to us in tandem with our first active experiments in observing the world and reaching out to explore it, and are still linked with those experiences.

Another factor in all of this, for Merleau-Ponty, is our social existence: we cannot thrive without others, or not for long, and we need this especially in early life. This makes solipsistic speculation about the reality of others ridiculous; we could never engage in such speculation if we hadn’t already been formed by them.

As Descartes could have said (but didn’t), ‘I think, therefore other people exist.’ We grow up with people playing with us, pointing things out, talking, listening, and getting us used to reading emotions and movements; this is how we become capable, reflective, smoothly integrated beings.

In general, Merleau-Ponty thinks human experience only makes sense if we abandon philosophy’s time-honoured habit of starting with a solitary, capsule-like, immobile adult self, isolated from its body and world, which must then be connected up again — adding each element around it as though adding clothing to a doll. Instead, for him, we slide from the womb to the birth canal to an equally close and total immersion in the world. That immersion continues as long as we live, although we may also cultivate the art of partially withdrawing from time to time when we want to think or daydream.

When he looks for his own metaphor to describe how he sees consciousness, he comes up with a beautiful one: consciousness, he suggests, is like a ‘fold’ in the world, as though someone had crumpled a piece of cloth to make a little nest or hollow. It stays for a while, before eventually being unfolded and smoothed away. There is something seductive, even erotic, in this idea of my conscious self as an improvised pouch in the cloth of the world. I still have my privacy — my withdrawing room. But I am part of the world’s fabric, and I remain formed out of it for as long as I am here.

By the time of these works, Merleau-Ponty is taking his desire to describe experience to the outer limits of what language can convey. Just as with the late Husserl or Heidegger, or Sartre in his Flaubert book, we see a philosopher venturing so far from shore that we can barely follow. Emmanuel Levinas would head out to the fringes too, eventually becoming incomprehensible to all but his most patient initiates.

Sartre once remarked — speaking of a disagreement they had about Husserl in 1941 — that ‘we discovered, astounded, that our conflicts had, at times, stemmed from our childhood, or went back to the elementary differences of our two organisms’. Merleau-Ponty also said in an interview that Sartre’s work seemed strange to him, not because of philosophical differences, but because of a certain ‘register of feeling’, especially in Nausea, that he could not share. Their difference was one of temperament and of the whole way the world presented itself to them.

The two also differed in their purpose. When Sartre writes about the body or other aspects of experience, he generally does it in order to make a different point. He expertly evokes the grace of his café waiter, gliding between the tables, bending at an angle just so, steering the drink-laden tray through the air on the tips of his fingers — but he does it all in order to illustrate his ideas about bad faith. When Merleau-Ponty writes about skilled and graceful movement, the movement itself is his point. This is the thing he wants to understand.

We can never move definitively from ignorance to certainty, for the thread of the inquiry will constantly lead us back to ignorance again. This is the most attractive description of philosophy I’ve ever read, and the best argument for why it is worth doing, even (or especially) when it takes us no distance at all from our starting point.

By prioritising perception, the body, social life and childhood development, Merleau-Ponty gathered up philosophy’s far-flung outsider subjects and brought them in to occupy the centre of his thought.

In his inaugural lecture at the Collège de France on 15 January 1953, published as In Praise of Philosophy, he said that philosophers should concern themselves above all with whatever is ambiguous in our experience. At the same time, they should think clearly about these ambiguities, using reason and science. Thus, he said, ‘The philosopher is marked by the distinguishing trait that he possesses inseparably the taste for evidence and the feeling for ambiguity.’ A constant movement is required between these two

As Sartre wrote in response to Hiroshima, humanity had now gained the power to wipe itself out, and must decide every single day that it wanted to live. Camus also wrote that humanity faced the task of choosing between collective suicide and a more intelligent use of its technology — ‘between hell and reason’. After 1945, there seemed little reason to trust in humanity’s ability to choose well.

Merleau-Ponty observed in a lecture of 1951 that, more than any previous century, the twentieth century had reminded people how ‘contingent’ their lives were — how at the mercy of historical events and other changes that they could not control. This feeling went on long after the war ended. After the A-bombs were dropped on Hiroshima and Nagasaki, many feared that a Third World War would not be long in coming, this time between the Soviet Union and the United States.

The researchers collected over five years of data from over a million runners, who collectively clocked in nearly 225 million miles. 

They noticed similar training patterns even if the runners were separated.

Weather, it turns out, did not dissuade one friend who saw their counterpart clocking in an extra ten minutes that day.

Risk of lagging behind proved to be a necessary catalyst for upping the ante. 

Which, obviously, is in good humor. But it helps.

As a 15-year-old, I was condemned to long-term solitary confinement in the Florida prison system, which ultimately lasted for 18 consecutive years

From age 15 to 33.

For 18 years I didn’t have a window in my room to distract myself from the intensity of my confinement

I wasn’t permitted to talk to my fellow prisoners or even to myself. I didn’t have healthy, nutritious food; I was given just enough to not die

These circumstances made me think about how I ended up in solitary confinement.

United Nations standards on the treatment of prisoners prohibits solitary confinement for more than 15 days, declaring it “cruel, inhuman or degrading.”

For this I was arrested and charged as an adult with armed robbery and attempted murder.

My court-appointed lawyer advised me to plead guilty, telling me that the maximum sentence would be 15 years. So I did. But my sentence wasn’t 15 years — it was life imprisonment without the possibility of parole.

But a year and a half later, at age 15, I was put back into solitary confinement after being written up for a few minor infractions.

Florida has different levels of solitary confinement; I spent the majority of that time in one of the most restrictive

I was finally released from prison in 2016 thanks to my lawyer, Bryan Stevenson

Researchers have long concluded that solitary confinement causes post-traumatic stress disorder and impairs prisoners’ ability to adjust to society long after they leave their cell.

In the summer of 1990, shortly after finishing seventh grade, I was directed by a few older kids to commit a robbery. During the botched attempt, I shot a woman. She suffered serious injuries to her jaw and mouth but survived. It was reckless and foolish on my part, the act of a 13-year-old in crisis, and I’m simply grateful no one died.

More aggressive change is needed in state prison systems

In 2016, the Obama administration banned juvenile solitary confinement in federal prisons, and a handful of states have advanced similar reforms for both children and adults.

Yet the practice, even for minors, is still common in the United States, and efforts to end it have been spotty

Because solitary confinement is hidden from public view and the broader prison population, egregious abuses are left unchecked

I watched a corrections officer spray a blind prisoner in the face with chemicals simply because he was standing by the door of his cell as a female nurse walked by. The prisoner later told me that to justify the spraying, the officer claimed the prisoner masturbated in front of the nurse.

I also witnessed the human consequences of the harshness of solitary firsthand: Some people would resort to cutting their stomachs open with a razor and sticking a plastic spork inside their intestines just so they could spend a week in the comfort of a hospital room with a television

On occasion, I purposely overdosed on Tylenol so that I could spend a night in the hospital. For even one night, it was worth the pain.

Another time, I was told I’d be switching dorms, and I politely asked to remain where I was because a guard in the new area had been overly aggressive with me. In response, four or five officers handcuffed me, picked me up by my feet and shoulders, and marched with me to my new dorm — using my head to ram the four steel doors on the way there.

The punishments were wholly disproportionate to the infractions. Before I knew it, months in solitary bled into years, years into almost two decades.

As a child, I survived these conditions by conjuring up stories of what I’d do when I was finally released. My mind was the only place I found freedom from my reality

the only place I could play basketball with my brother or video games with my friends, and eat my mother’s warm cherry pie on the porch.

No child should have to use their imagination this way — to survive.

It is difficult to know the exact number of children in solitary confinement today. The Liman Center at Yale Law School estimated that 61,000 Americans (adults and children) were in solitary confinement in the fall of 2017

No matter the count, I witnessed too many people lose their minds while isolated. They’d involuntarily cross a line and simply never return to sanity. Perhaps they didn’t want to. Staying in their mind was the better, safer, more humane option.

Solitary confinement is cruel and unusual punishment, something prohibited by the Eighth Amendment, yet prisons continue to practice it.

When it comes to children, elimination is the only moral option. And if ending solitary confinement for adults isn’t politically viable, public officials should at least limit the length of confinement to 15 days or fewer, in compliance with the U.N. standards

Two years ago, Democrats excoriated Trump administration officials for its handling of the crisis at the border. Now the problem is squarely within Biden's domain and government resources are once again strained to the brink as more than 600 unaccompanied children cross the Mexico border each day.

"We're not seeing any action. Our experience has taught us that now is the time to act. We need Congress to get on board. We need a recognition of the fact that there's a crisis on the Southwest border," Roy Villareal, who served as chief patrol agent in the Tucson sector from 2018 to 2020, told CNN's Priscilla Alvarez.

"It's a huge problem. I'm not going to pretend that it's not. It's a huge problem," Harris said in remarks that appeared to be somewhat of a do-over of the administration's initial downplaying of the situation.
