I can have the illusion of choice, sure.

btw did you see a recent BBC documentary called "Are you good or evil?" it was about the inborn biological causes of behaviour.
Once you take away the social and biological influences on behaviour and choice - I'm not sure what is left?
Yes, there are many good arguments against the idea of any human volition. However, before we get to any of the arguments, we can always be skeptical of rationality's ability to conceptualize. Establishing an objective truth about anything is, as many good arguments also show, futile. Faced with this reality, I feel our true hope of any knowledge is through the actual given nature of our experience, a truth that is true beyond all doubt.
I may not ever be right that the yellow and round thing I see is the sun, but I can never be mistaken that the object of my consciousness is yellow and round. I could be a brain in a vat, my entire world a fiction, an illusion, but the fact is I have experienced a yellow and round object.
Analogously then, we can extend the same sound facticity to all of the given phenomena of our experience. One of these phenomena is the given nature of human volition, our ability to create, to act, to choose.
