What is more interesting than free will? Jerry Coyne finds it interesting, anyway.
Also Sam Harris, according to Coyne. During my endless commutes I have been listening to lectures by John Searle on the philosophy of mind, and he openly admits he hates lecturing on free will, because he has no good solution for it. The only way he can make sense of free will is by invoking quantum indeterminacy, and he openly warns you to stop believing philosophers when they bring up quantum indeterminacy.
