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 The Golden Compass – a lead ballon? 29 Dec 2007 Henry Gee reviews the Golden Compass, and comes up with largely the same conclusions I would have had I been as insightful as he. A quote: It’s a long time since I read the book, The Northern Lights, on which the film is based, so perhaps it’s a problem with… Read More
Evolution ROUS’s? I don’t believe they exist. 15 Jan 2008 Anyone who knows the film The Princess Bride knows what happens next. Westley gets hit hard by a rodent about the size of a pitbull. However, it seems that ROUS’s (Rodents of Unusual Size) actually may have existed, in Uruguay. Nature reports that the skull of one has been discovered,… Read More
History A plea for the pope 17 Jan 200818 Sep 2017 This isn’t something I would often write, but I think that the recent protest against the Pope speaking at the secular university La Sapienza in Rome is misplaced. Critics say that the Pope, when he was of more humble rank, had in 1990 defended the Inquisition’s judgement against Galileo in… 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.
