[Pinker] conflates scientific knowledge with knowledge as such. In his view, anybody who has studied any phenomena that are studied by science has been a scientist...If they were interested in the mind, then they were early versions of brain scientists. If they investigated human nature, then they were social psychologists or behavioral economists avant la lettre
. Leon Wieseltier pens a response
to Steven Pinker's essay
on scientism, both in the pages of the New Republic. Others
some prominent atheists
, have taken issue with Pinker as well.

"One might think that, once we know something is computable, how efficiently it can be computed is a practical question with little further philosophical importance. In this essay, I offer a detailed case that one would be wrong. In particular, I argue that computational complexity theory---the field that studies the resources (such as time, space, and randomness) needed to solve computational problems---leads to new perspectives on the nature of mathematical knowledge, the strong AI debate, computationalism, the problem of logical omniscience, Hume's problem of induction, Goodman's grue riddle, the foundations of quantum mechanics, economic rationality, closed timelike curves, and several other topics of philosophical interest. I end by discussing aspects of complexity theory itself that could benefit from philosophical analysis."

The concept of nothing is as old as zero itself. How do we grapple with the concept of nothing? From the best laboratory vacuums on Earth to the vacuum of space to what lies beyond, the idea of nothing continues to intrigue professionals and the public alike.
Join moderator and Hayden Planetarium Director Neil deGrasse Tyson
as he leads a spirited discussion with a group of physicists, philosophers and journalists about the existence of nothing. The event, which was streamed live to the web, took place at the American Museum of Natural History on March 20, 2013. [more inside]

The Nature of Computation
- Intellects Vast and Warm and Sympathetic
: "I hand you a network or graph, and ask whether there is a path through the network that crosses each edge exactly once, returning to its starting point. (That is, I ask whether there is a 'Eulerian' cycle.) Then I hand you another network, and ask whether there is a path which visits each node exactly once. (That is, I ask whether there is a 'Hamiltonian' cycle.) How hard is it to answer me?" (via

Heaven is Real: A Doctor's Experience of the Afterlife. As a neurosurgeon, I did not believe in the phenomenon of near-death experiences...In the fall of 2008, however, after seven days in a coma during which the human part of my brain, the neocortex, was inactivated, I experienced something so profound that it gave me a scientific reason to believe in consciousness after death.

Are you the type of person who, when flipping through a book or scanning a website, immediately searches for the diagrams or charts because you'd rather absorb the information visually than have to read a bunch of text? If so, then you are probably a visual learner and you may find Useful Charts
helpful. The goal is to present useful information in the form of study charts so that students, teachers or simply those interested in increasing their general knowledge can absorb the information quickly and visually.

Morton and Vicary on the Categorified Heisenberg Algebra
- "In quantum mechanics, position times momentum does not equal momentum times position! This sounds weird, but it's connected to a very simple fact. Suppose you have a box with some balls in it, and you have the magical ability to create and annihilate balls. Then there's one more way to create a ball and then annihilate one, than to annihilate one and then create one. Huh? Yes: if there are, say, 3 balls in the box to start with, there are 4 balls you can choose to annihilate after you've created one but only 3 before you create one..." [more inside]

Stanley Fish takes on the similarities and differences
between scientific and religious evidence and gets a barrage of responses, to which he replies
. Michael K. declares that “the equivalence between the methodological premises of scientific inquiry and those of religious doctrine is simply false.” I agree, but I do not assert it. Neither do I assert that because there are no “impersonal standards and impartial procedures … all standards and procedures are equivalent” (E.). What I do assert is that with respect to a single demand — the demand that the methodological procedures of an enterprise be tethered to the world of fact in a manner unmediated by assumptions — science and religion are in the same condition of not being able to meet it (as are history, anthropology, political science, sociology, psychology and all the rest).

Out-of-body experience: Master of illusion
: Out-of-body experiences are just part of Ehrsson's repertoire. He has convinced people that they have swapped bodies with another person, gained a third arm, shrunk to the size of a doll or grown to giant proportions.
[ . . . ]
But Ehrsson's unorthodox apparatus amount to more than cheap trickery. They are part of his quest to understand how people come to experience a sense of self, located within their own bodies. The feeling of body ownership is so ingrained that few people ever think about it — and those scientists and philosophers who do have assumed that it was unassailable.
[ . . . ]
Ehrsson's work also intrigues neuroscientists and philosophers because it turns a slippery, metaphysical construct — the self — into something that scientists can dissect.

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust
": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it
. It all depends how you think it.

"You turned into a cat! A
SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signaling! And cats are
COMPLICATED! A human mind can't just visualize a whole cat's anatomy and, and all the cat biochemistry, and what about the
neurology? How can you go on thinking using a cat-sized brain?" McGonagall's lips were twitching harder now. "Magic."

First Person Plural.
"An evolving approach to the science of pleasure suggests that each of us contains multiple selves—all with different desires, and all fighting for control. If this is right, the pursuit of happiness becomes even trickier. Can one self bind another self if the two want different things? Are you always better off when a Good Self wins? And should outsiders, such as employers and policy makers, get into the fray?" [Via]

-- or as O'Reilly might term the Social Graph
-- sort of mirrors the debate on 'brute force' algorithmic proofs
(that are "true for no reason
.) in which "computers can extract patterns in this ocean of data that no human could ever possibly detect. These patterns are correlations. They may or may not be causative
, but we can learn new things. Therefore they accomplish what science does, although not in the traditional manner... In this part of science, we may get answers that work, but which we don't understand. Is this partial understanding? Or a different kind
?" Of course, say some in the scientific community: hogwash
; it's just a fabrication of scientifically/statistically illiterate pundits, like whilst new techniques in data analysis
are being developed to help keep ahead of the deluge...
