I've recently thought about the nature of voluntary actions (such as raising a hand) and they seem absolutely confounding to me. Its not as if you instruct your brain to do the action, you just do it. But because of what? If I reflect upon the everyday voluntary actions I do, from simply waking to moving my hand to talking, its not like I anticipate it, it just happens. I am utterly confused about the origin of these sort of actions and how one should view them.
