You think you're talking about free will, but what you're describing is illusion of free will dictated by mechanistic action. In other words, you're free to choose what the maze decides.

I strongly disagree. I've made choices that go against every possible mechanistic explanation...they have flown against how I was raised, what I experienced, or my genetics or culture. I made them because I decided they were "right".

And I've pulled myself out of deeply ingrained patterns of behavior because someone I love told me I had a problem. It was love that made the change, not a bunch of chemical reactions. If anything the chemicals reactions were keeping me in the same place as before.

The essential question is do the atoms control us or do we control the atoms? I think this differs from person to person, but we can control our own lives if we choose to.
