Steve H,
My brain hurts.
Think of it this way: nature has no remit to correlate your
experience of things with the way they actually
are. Rather nature's remit is optimise the survival of genes. If experiencing your "will" as if it were "free" serves that purpose, then well and good.
AB's mistake is to be so emotionally wedded to the idea that his will is actually "free" (and then to conjure up a menagerie of "souls" and the like to make sense of that) that he cannot bear to accept the logically coherent alternative. It's a basic error in reasoning called the
argumentum ad consequentiam that's been explained to him many times, but he clings to it as a man clings to concrete lifebelt nonetheless.
