I think ultimately we arent volitional. We are a purely physical state effected by our environment. It's a constant equation, one thought always preceded by another in destinys path. Everything is fate... since its all an equation, everything was always going to eventuate this way.
It's ironic though, the system that provides no free will is naturally designed to make you believe you do have free will. Probably essential for ego health. Since I am not a practising Zen buddhist, I do like to live in the fantasy that i have free will.
