“One appears to conclude from these experiments that: (i) the conscious act of 'free will' is a pure illusion, having been, in some sense, already preprogrammed in the preceding unconscious activity of the brain; or (ii) there is a possible 'last-minute' role for the will, so that it can sometimes (but not usually) reverse the decision that had been unconsciously building up for a second or so before; or (iii) the subject actually consciously wills the finger-flexing at the earlier time of a second or so before the flexing takes place, but mistakenly perceives, in a consistent way, that the conscious act occurs at the much later time, just before the finger is indeed flexed.”
