    "A Brief Introduction All our science, measured against reality, is primitive and childlike - and yet it is the most precious thing we have. -Albert Einstein The Skeptics Society is a scientific and educational organization of scholars, scientists, historians, magicians, professors and teachers, and anyone curious about controversial ideas, extraordinary claims, revolutionary ideas, and the promotion of science. Our mission is to serve as an educational tool for those seeking clarification and viewpoints on those controversial ideas and claims. Under the direction of Dr. Michael Shermer, the Society engages in discussions with leading experts and investigates fringe science and paranormal claims. It is our hope that our efforts go a long way in promoting critical thinking and lifelong inquisitiveness in all individuals. I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them. -Baruch Spinoza Some people believe that skepticism is the rejection of new ideas, or worse, they confuse "skeptic" with "cynic" and think that skeptics are a bunch of grumpy curmudgeons unwilling to accept any claim that challenges the status quo. This is wrong. Skepticism is a provisional approach to claims. It is the application of reason to any and all ideas - no sacred cows allowed. In other words, skepticism is a method, not a position. Ideally, skeptics do not go into an investigation closed to the possibility that a phenomenon might be real or that a claim might be true. When we say we are "skeptical," we mean that we must see compelling evidence before we believe. Skepticism has a long historical tradition dating back to ancient Greece, when Socrates observed: "All I know is that I know nothing." But this pure position is sterile and unproductive and held by virtually no one. If you were skeptical about everything, you would have to be skeptical of your own skepticism. Like the dec

    "The Death and Life of Great American Cities, by Jane Jacobs, is a greatly influential book on the subject of urban planning in the 20th century. First published in 1961, the book is a critique of modernist planning policies claimed by Jacobs to be destroying many existing inner-city communities. Reserving her most vitriolic criticism for the "rationalist" planners (specifically Robert Moses) of the 1950s and 1960s, Jacobs argued that modernist urban planning rejects the city, because it rejects human beings living in a community characterized by layered complexity and seeming chaos. The modernist planners used deductive reasoning to find principles by which to plan cities. Among these policies the most violent was urban renewal; the most prevalent was and is the separation of uses (i.e. residential, industrial, commercial). These policies, she claimed, destroy communities and innovative economies by creating isolated, unnatural urban spaces. In their place Jacobs advocated for "four generators of diversity", writing on page 151, "The necessity for these four conditions is the most important point this book has to make. In combination, these conditions create effective economic pools of use." Mixed uses. Short blocks. Buildings of various ages & states of repair. Density. Her aesthetic can be considered opposite to that of the modernists, upholding redundancy and vibrancy, against order and efficiency. She frequently cites New York City's Greenwich Village as an example of a vibrant urban community. The Village, like many similar communities, may well have been preserved, at least in part, by her writing and activism. The book also played a major role in the urban development of Toronto, Ontario, Canada, where Jacobs was involved in the campaign to stop the Spadina Expressway.[1] The book continues to be Jacobs' most influential, and is still widely read by both planning professionals and the general public. Urban theorist Lewis Mumford, while f

book decolonize the media occupy

  • If you look at the full suite of information tools that were employed to spread the revolutions of 2009–11, it goes like this: Facebook is used to form groups, covert and overt – in order to establish those strong but flexible connections. Twitter is used for real-time organisation and news dissemination, bypassing the cumbersome newsgathering operations of the mainstream media. YouTube and the Twitter-linked photographic sites – Yfrog, Flickr and Twitpic – are used to provide instant evidence of the claims being made. Link-shorteners such as bit.ly are used to disseminate key articles via Twitter.
  • Underpinning the social media is mobile telephony: in the crush of every crowd we see arms holding cellphones in the air, like small flocks of ostriches, snapping scenes of repression or revolt, offering instant and indelible image-capture to a global audience.And in all the theatres of revolution, blogs have offered a vital resource: somewhere to link to.

  • Psychologists and neurobiologists have begun studying what goes on in our minds as we read literature, and what they’re discovering lends scientific weight to Emerson’s observation.
  • “aesthetic emotions” that we feel when we view art from a distance, as a spectator:
  • We create our own version of the piece of fiction, our own dream, our own enactment.” Making sense of what transpires in a book’s imagined reality appears to depend on “making a version of the action ourselves, inwardly.”
  • ...21 more annotations...
  • The scholars used brain scans to examine the cellular activity that occurs inside people’s heads as they read stories. They found that “readers mentally simulate each new situation encountered in a narrative.”
  • When, for example, a character in a story puts a pencil down on a desk, the neurons that control muscle movements fire in a reader’s brain. When a character goes through a door to enter a room, electrical charges begin to flow through the areas in a reader’s brain that are involved in spatial representation and navigation.
  • More than mere replication is going on.
  • we really do enter, so far as our brains are concerned, a new world — one conjured not just out of the author’s words but out of our own memories and desires — and it is our cognitive immersion in that world that gives reading its emotional force.
  • ” A work of literature, particularly narrative literature, takes hold of the brain in curious and powerful ways.
  • there are the “narrative emotions” we experience when, through the sympathetic actions of our nervous system, we become part of a story, when the distance between the attendee and the attended evaporates
  • A 2009 experiment conducted by Oatley and three colleagues suggests that the emotions stirred by literature can even alter, in subtle but real ways, people’s personalities.
  • Norman Holland, a scholar at the McKnight Brain Institute at the University of Florida, has been studying literature’s psychological effects for many years, and he offers a provocative answer to that question.
  • when we open a book, our expectations and attitudes change. Because we understand that “we cannot or will not change the work of art by our actions,” we are relieved of our desire to exert an influence over objects and people and hence can “disengage our [cognitive] systems for initiating actions.”

      Theory of mind 
  • The central subject of literature is society, and when we lose ourselves in a book we often receive an education in the subtleties and vagaries of human relations.
  • reading tends to make us at least a little more empathetic, a little more alert to the inner lives of others.
  • can strengthen a person’s “theory of mind,” which is what psychologists call the ability to understand what other people are thinking and feeling.
  • That frees us to become absorbed in the imaginary world of the literary work.
  • Jeff Jarvis, a media consultant who teaches journalism at the City University of New York, gave voice to this way of thinking in a post on his blog. Claiming that printed pages “create, at best, a one-way relationship with a reader,” he concluded that, in the internet era, “the book is an outdated means of communicating information.” He declared that “print is where words go to die.”
  • Society is growing ever more skeptical of the value of solitude. The status quo treats with suspicion  even the briefest of withdrawals into inactivity and apparent purposelessness. We see it in the redefinition of receptive states of mind as passive states of mind.
  • the arts of production and consumption, of getting stuff done, to which most of us devote most of our waking hours.
  • In a 2003 lecture, Andrew Louth, a theology professor at the University of Durham in England, drew a distinction between “the free arts” and “the servile arts.” The servile arts, he said, are those “to which a man is bound if he has in mind a limited task.”
  • free arts, among which Louth included reading as well as meditation, contemplation, and prayer, are those characterized, in one way or another, by “the search for knowledge for its own sake.”
  • We open ourselves to aesthetic and spiritual possibilities.
  • It may be that readers have to enter a state of languid pleasure, a dream, before they can experience the full spermatic vitality of a book. Far from being a sign of passivity, the reader’s outward repose signals the most profound kind of inner activity, the kind that goes unregistered by society’s sensors.

Gaia Margulis evolution process

shared by David McGavock on 30 Mar 14 - No Cached
  • This journey led her to emphasize in all her scientific work two phenomena -- the fusing of distinct beings into a single being: symbiosis; and the interaction of organisms and their environments to create relational "loops" that led to regulation of many Earth systems: Gaia Theory.
  • Bacteria were here first and are with us still, comprising a major part of the biosphere.  They are unseen with the naked eye, they lack nuclei (for this reason, they are called prokaryotes -- "pro" = before,  "karyon" = nucleus). Their forms were legion and their metabolisms were (and continue to be) strange.
  • What is known is that the spirochete didn't digest the thermoplasmid and the thermoplasmid did not digest the spirochete.  As Margulis was fond of saying, "1 + 1 = 1."  There was a union of the two, resulting in an entirely new being.  They were inseparable, literally.  The thermoplasmid had a rotor now, and the spirochete had a "head".
  • ...24 more annotations...
  • Margulis, inspired by the work of little-known biologists, revealed and proved these mergers for us.  At first, her worked was rejected and scoffed at.  It did not fit the still-dominant neo-Darwinian paradigm that tells us all evolutionary novelty comes from natural selection acting on genes and the gradual accumulation of random genetic mutation.  But eventually these symbioses were accepted because they could not be ignored
  • our physical selves are universes composed of the movemenst, biological agreements, and interactions of these beings.
  • "Identity is not an object; it is a process with addresses for all the different directions and dimensions in which it moves..." Margulis once stated, with her colleague Ricardo Guerrero.
  • Indeed, symbiogenesis has been observed in the lab.  An amoeba population, accidentally infected with bacteria was observed over long periods of time, and soon enough, the infecting bacteria could not be removed from the infected amoeba without killing the organism. 
  • Gaia is the work of the relational loops of push and pull between bacteria, other organisms, and the environment
  • But Lovelock came up with an understandable and accesible metaphor in the form of a computer program called Daisyworld.  Daisyworld is not the "proof" of Gaia: Lovelock and his colleague Andrew Watson devised the program to see if living and environmental factors could theoretically interact without intention. 
  • "Gaia," Margulis's former student Greg Hinkle said, "is just symbiosis as seen from space."
  • Gaia processes are real and observable (and sometimes referred to as "biogeochemistry", a term more acceptable to mainstream science).  Furthermore, the five kingdoms (bacteria, protoctists, fungi, plants, animals) of life are all touched by symbiosis
  • After she found James Lovelock, they worked on making those processes known.  Their collaboration resulted in Gaia Theory, which was a disciplinary symbiosis -- the theoretical expression of Margulis's interdisciplinary life.
  • All animals have symbiotic partners in their guts.  Remove these symbionts and the animals die.
  • Microcosmos show us a bacterial view of the world.  Bacteria exchange their genes laterally.  This means they don't pass their genomic information only when they reproduce (though this can happen), but also  through their simple existence.
  • Along with the many detailed examples of bacterial mergers at varying levels of cellular complexity, the world revealed by Acquiring Genomes is also a world of mating between distinct phyla
  • What is definite is that the merging of beings is key, and symbiogenesis offers a clearly observable alternative to the consistent but woefully incomplete neo-Darwinian paradigm.
  • David Bohm, who said
  • "Science is the search for truth...whether we like it or not."
  • Many neo-Darwinist concerns circled nervously around words like "Gaia" and "cooperation" (which Margulis did not like to use).  They were, perhaps rightly, concerned that these terms were ripe for religious appropriation.  But Margulis herself was outspoken against such mishandling of her research.

      Cooperation - not God - meets Gaia
  • it's much more complex than that -- there is something "in it" for every symbiont,
  • "Gaia is not merely an organism."  The Earth is beyond stale conception.  It is more magnificent and active than we can imagine.  Gaia is object and process.
  • this complexity is impossible to incorporate in a linear and reductive understanding.
    • David McGavock
      David McGavock on 30 Mar 14
       
      This is a question that I often wonder - how different thinkers (using different modes of understanding) come to different conclusions.  What is it that separates the linear (reductive) thinker from the holistic (systemic) thinker?
  • If Gaia is conscious, it possesses a consciousness of a different magnitude, probably of a different order all together.
  • Perhaps as we -- in the newly and deeply connected world of the internet, social profiles, and globalization -- witness the dissolution of the cult of isolated individuality and embark on understanding a clearer and more nuanced view of individuality, so to will we ready ourselves for a clearer view of evolution and life.
    • David McGavock
      David McGavock on 30 Mar 14
       
      This is a good question; how does this connected world reframe our conception of ourselves as individuals? Can we, at once, become humbled while we contribute? Can we imagine ourselves as less important while we excel in our pursuits?
  • Dawkins, who claims to be an atheist, relies on a host of selfish angels within us and the possibility for meme-salvation to justify his theory.  He substantiates his magical worldview on a meager past of scientific work.
  • To encompass complex systems with our thinking, we must imagine a model that is less like "cause-effect" more like "being-manifestation."  That is, multiple layers and numerous agents of forces unconsciously conspire together, and their conspiring is so intermingled, that it is simultaneously cause and effect, and thus beyond both. 
  • Now that Margulis has died, it remains our choice to catch up with what she and her life's work have set in motion.  To do so, we must bring together the many fields of knowledge she embodied.  Biologists must talk to physicists, virologists must talk to geologists, cosmologists must talk to microbiologists, and scientists musty talk to non-scientists.  This motion of meeting and exchanging ideas, if we act with it, will evolve our thinking.
