When I discuss this with people almost everyone take for granted that their will is theirs to control. It is hard to prove it otherwise. The reason for that is that humans feel on a deep level that there is choice. You can discuss this philosophically of course, and research begin to show that there is much we do not understand yet, but until the moment comes when humans feel that they
do not have free will, they will speak and act as they have it.
If research do conclude that the will is not ours, what will change? Will our consciousness and awareness change, so that we become something other than human? The notion of free will is what makes us human right? It is what supposedly separates us from other beings, so if we evolve past that notion, what will we become then?
As I have mentioned in other threads I think neuroscience will arrive at the same conclusion as eastern philosophy has toyed with, namely that "self" and "free will" is illusory. Buddhists, Hindus etc deal with this notion through mental training etc, but how does the western mind prepare for this "new" knowledge? Personally I think we will deal with it through technological innovation, but this is just guessing

Will just finish by saying that I am not at all well read in these topics, but I do regard them as deeply human, and since I am a human, I think we are capable of expressing our feelings towards them whether you are well read or not.
