The man with a tumor has no choice but to do what he does. I do have choices, which I make all the time. Yes, my choices are constrained, by the laws of physics, my genetic inheritance, upbringing and education, the social, cultural, political, and intellectual context of my existence. And as Harris keeps pointing out, I didn’t choose to be born into this universe, to my parents, in this nation, at this time. I don’t choose to grow old and die.But just because my choices are limited doesn’t mean they don’t exist. Just because I don’t have absolute freedom doesn’t mean I have no freedom at all. Saying that free will doesn’t exist because it isn’t absolutely free is like saying truth doesn’t exist because we can’t achieve absolute, perfect knowledge.
Okay, that's good, right there. Good points. Now, hold up a minute; let's just look closer at what we mean by "choice" and "free" will, and then we should be— wait, what are you...? Hey, no, don't... aww, c'mon, really, don't say th...! Aww, man...
But the strange and wonderful thing about all organisms, and especially our species, is that mechanistic physical processes somehow give rise to phenomena that are not reducible to or determined by those physical processes. Human brains, in particular, generate human minds, which while subject to physical laws are influenced by non-physical factors, including ideas produced by other minds....We are physical creatures, but we are not just physical. We have free will because we are creatures of mind, meaning, ideas, not just matter. Harris perversely–willfully!–refuses to acknowledge this crushingly obvious and fundamental fact about us.
Sigh. It looked so promising for a moment there.
