Stephen Hawking: “Nothing” has more explanatory value than “God”
Posted by Wes Alwan in Web Detritus on September 7th, 2010
Stephen Hawking makes perhaps one of the dumbest forays by a scientist into philosophy that I have ever seen:
That is not the answer of modern science. As recent advances in cosmology suggest, the laws of gravity and quantum theory allow universes to appear spontaneously from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.
Well that settles it. Something spontaneously arose out of nothing. No need for an explanation of that. Move on people, nothing mysterious here, stop asking questions. The blue touch paper lit itself, and there is something called “nothingness” which contains that blue torch paper as well as laws governing it. Perhaps this is all, in some Deepak Chopra sense, true. But it is not “the answer of modern science.” It is purely speculative, and whether we want to use the word “God” to describe the mystery of spontaneous generation or leave it at a nothing containing the seed of spontaneous generation seems to be a semantic distinction, with the latter in no way naturalizing or demystifying the former.

Reading Pragmatism by William James and “The Fixation of Belief” and “How to Make Our Ideas Clear” by Charles Sanders Peirce.
Is truth a primitive relation between our representations and things objectively in the world, or is it an analyzable process by which propositions “prove their worth” by being useful in some way, like by fitting well with other portions of our experience or being delicious?
Peirce, the inventor of pragmatism, focuses on the philosophy of science and thinks of inquiry as a way for us to just settle on any belief we can stomach. James, who popularized pragmatism, has a wider view that applies not only to science but to religious beliefs. If it makes you feel nice to believe in Hogwarts, should you do so?
The episode features guest podcaster Dylan Casey (previously from our quantum physics episode).
The readings are at http://www.gutenberg.org/etext/5116, http://www.peirce.org/writings/p107.html, and http://www.peirce.org/writings/p119.html. Another helpful link we talk about is the chapter from James’s book The Meaning of Truth where he responds to objections: http://www.brocku.ca/MeadProject/James/James_1911/James_1911_08.html

Are the majority of published scientific research claims false?
Posted by Wes Alwan in Web Detritus on March 20th, 2010
The epistemology vs. epidemiology (Odds Are, It’s Wrong – Science News):
“There is increasing concern,” declared epidemiologist John Ioannidis in a highly cited 2005 paper in PLoS Medicine, “that in modern research, false findings may be the majority or even the vast majority of published research claims.”
…
Nowhere are the problems with statistics more blatant than in studies of genetic influences on disease.
…
Statisticians perpetually caution against mistaking statistical significance for practical importance, but scientific papers commit that error often. Ziliak studied journals from various fields — psychology, medicine and economics among others — and reported frequent disregard for the distinction.
…
Such sad statistical situations suggest that the marriage of science and math may be desperately in need of counseling.
…
“What does probability mean in real life?” the statistician David Salsburg asked in his 2001 book The Lady Tasting Tea. “This problem is still unsolved, and … if it remains un solved, the whole of the statistical approach to science may come crashing down from the weight of its own inconsistencies.”
Fodor, Darwin, and the Philosophy of Science
I had been looking forward to Jerry Fodor’s What Darwin Got Wrong (co-authored with Massimo Piattelli-Palmarini), not because I have anything against Darwin but because Fodor is a superb writer, the well-respected cognitive scientist who “laid the groundwork for the modularity of mind and language of thought hypotheses,” and a worthy opponent of the idiocy of evolutionary psychologists who seem to think that every phenotypic trait must have been subject to selective pressure (no).
The book is extremely disappointing, and I don’t have the heart a the longer post analyzing it. It’s enough to read Ned Block (fantastic philosopher of mind guy) and Philip Kitcher’s review–that is, complete dismantling of a thesis that just seems bizarrely wrong. F&PP’s response and B&K’s reply are also very interesting. I will say that B&K’s accusation that the book shows “no detailed engagement with the practice of evolutionary biology” is an ad hominem overreach. The book gives a competent (and extremely informative) overview of the field, even if it is mistaken about its implications. Earlier in the review, F&K merely call it “biologically irrelevant”–an accurate claim if the relevance is to F&PP’s philosophical argument. But this merely highlights the fact that the book’s problems are philosophical, not biological.
(I’m going to apologize in advance for the intemperance of the rest of this screed).
These claims are particularly unfortunate in that they have encouraged an outpouring of zealous and anti-intellectual scientism by reviewers (not to mention comment section trolls) who make no claims even to have read the book and assume its flaws must be scientific rather than philosophical. The they-just-don’t-understand-science claim has become a rationale for berating philosophers for their pie-in-the-sky impracticality (historically inducing in a certain species of self-hating philosopher the kind of it’s-not-science insecurities that lead to patently self-inconsistent theories as verificationism, not to mention the bevy of other views amounting to: “I’ve found the solution to all philosophical problems! There are none!” (Premise: any problem that threaten to limit the domain of scientific inquiry must not be a problem for science)).
So let me say this (first thesis): that you are a scientist does not mean he understands what your endeavor entails, any more than being a soccer player means understanding the physics and anatomy involved in the playing of soccer. That understanding requires reflection on the doing of science, not merely the accumulation of laboratory hours. Further, Ruse and others seems not understand or even be curious about issues in the philosophy of science or mind about which they are emboldened to spew by virtue of a kind of diplomatic immunity involved in calling themselves “scientist” (Ruse absurdly accuses Nagel, for instance, of being a “vitalist,” and assumes that physicalism is an easy solution to the mind-body problem–it would help him to familiarize himself with the literature and the fact that Nagel wrote the seminal anti-reductionist paper on the subject, What is it Like to be a Bat? If he thinks its claims are absurd, he ought to produce an argument, not a mere “that don’t sound scientific.”). So, second thesis: being a scientist does not immunize you from the requirement to think. Nor is being a scientist relevant to the soundness of your claims--it is not a slam-dunk in every science-related dispute. The (ad hominem) concept of that immunization is itself highly anti-rational (many scientists, of course, make no bones of their anti-intellectualism beyond the boundaries of the petri dish–and arguably this motivates some reductionist accounts).
I’m now going to apologize again for the intemperance of my screed, and I’d like to point out that I have a longstanding love of science (one of my undergraduate majors is the history of science). I have no truck with creationists/intelligent design adherents on the one hand or post-modern relativists on the other. But just as love of country entails honest self-critique … well you get the picture. This sort of credential-offering shouldn’t be necessary–it’s just a kind of preparation for being called the kinds of names that members of a loyal opposition get called. Suffice it to say that I simply believe scientism and anti-philosophical zealotry do nothing for science, any more than teabagging with a sign saying “freedom” does something for freedom. And in general, reductionism is just bad philosophy and has no bearing on the everyday practice of science or its esteemed status, except insofar as recognizes a limit to the domain of empirical scientific inquiry based on … whether or not the relevant data is susceptible to empirical scrutiny. Whether or not a neuroscientist believes that brain states are identical to mental states (as opposed to having some other sort of relation) will make no difference to his everyday work; but it will be relevant to his extra-curricular spoutings on God and Mind and Free Will and the rest–spoutings which which lead the dumb reductionist mythologies that pervade popular culture.
