If we then define free will as the ability to consciously influence the outcome of reality, determinism necessarily precludes it. — ho ching leung

If I lift up my arm, I am having an effect on the real world and I am conscious of this. I call my "choice" to do this a choice, without the quotation marks, and so does everyone else in the world, even the libertarian free willers when they are not specifically considering philosophy. I am responsible for my actions unless they are accidental, forced or due to some abnormal mental state such as mental illness. I cannot claim diminished responsibility for a crime in court on the grounds that my actions are caused by prior events, but I probably could if I showed the opposite, that I suffered from a neurological disease that makes my actions undetermined.
