I need a better name for it.
The Experiment: A Laplacian demon with exhaustive knowledge of the wave function of the universe hands you a sheet of paper that specifies whether you will be standing or not standing 30 seconds from now. He repeats the experiment ten times. You are entirely aware of everything the machine is trying to do, and you are hostile to its intentions. Will his predictions be necessarily true, that is, true no matter what you think about the matter?
Sean Carroll, for all his attempts to juggle clarity and nuance, is committed to saying yes. Einstein just said yes flat out. I’m constitutionally incapable of taking a “yes” as anything other than a reductio ad absurdum of any premise logically connected to it.
A failure of the Full-Libet limits the domain of physical law to those motions not initiated by intelligence. Given the infinitesimally small percentage of motions in the universe that fit this description, this is in one sense an insignificant qualification.
