I've heard there are people in philosophy called "action theorists" who think that action is always the product of one's own beliefs and desires. This view of action seems to call into question our free will. I know that I don't choose my desires and it really doesn't seem like I choose my beliefs either (e.g. I can't just choose to disbelieve that the earth revolves around the sun). So, if action is just the product of beliefs and desires, and I can't choose those, what room is left for me to choose my actions?
