Vale Wheeler, and Libet updated 14 Apr 2008 Daniel Holz at Cosmic Variance has a beautifully written obit for John Wheeler. We are grateful for the time the great thinkers spend on us students. Wired has an article on the updating of the classic experiments by Benjamin Libet on the fact that conscious choices occur after the brain has already begun a task. General Science History
General Science On what Quine was… 22 Jun 2008 Willard Van Ormond Quine was, I believe, one of the best of the 20th century philosophers, and is someone who has greatly influenced me. Here is a TV interview by Brian Magee, from the 1970s, if I am right. They discuss the nature of philosophy. This year marks the centenary… Read More
Biology The Velvet Underground of… 8 Oct 2010 Recently there have been a couple of “Velvet Underground” posts, of the kind that the VU were a very unknown but amazingly influential group. As Chad Orzel says, “only of order a thousand people bought the first Velvet Underground record, but every one of them went on to start a… Read More
Administrative Academic genealogies 29 Oct 2010 Wasting time usefully with my friend and co-student of Gareth Nelson, Malte Ebach, we wondered what our academic genealogies were. My thesis advisors were Gareth J. Nelson and Neil Thomason. Gary was advised by William A. Gosline (1915-2002), who was advised by George Sprague Myers (1905-1985), who was a student… Read More
This (Libet) seems to be another nail in the coffin of mind/body dualism. If the brain is busy doing the requisite work for a decision long before we’re aware of our decision, then it can’t been a separate mind doing the decision making. Brain functioning seems to be the mind. This is what my psych unit teaches anyway. Add to that the fact that a immaterial brain has to violate the law of conservation of energy to affect a material brain/body and dualism seems in trouble. Or have I misunderstood everything?

Shades of Ted Chiang’s “What’s Expected of Us” — though (@Brian) he uses it to make a point about determinism, not dualism.
What a piece of bunk. You can see a more concise description under http://www.nature.com/neuro/journal/vaop/ncurrent/full/nn.2112.html and the supplementary figures under http://www.nature.com/neuro/journal/vaop/ncurrent/suppinfo/nn.2112_S1.html The prediction accuracy before the conscious decision is 60% and jumps to 75% when SMA is activated (which is *after* the conscious decision). That is lousy and doesn’t legitimate the wording “Taken together, the patterns consistently predicted whether test subjects eventually pushed a button with their left or right hand”. Dear friends, 60% isn’t a “consistent prediction” and telling that “not completely accurate” is a severe understatement.
