ABSTRACT
The soft determinists' point of view is often called the Hume-Mill theory. Sometimes he talks as if objective association is the principal ingredient of causation, sometimes he uses the more subjective notion of association in the mind. The libertarian's point, which survives through any analysis of causation, is that if there were no real possibility of Mary doing other than what she did, then the normal sense of moral responsibility says that she is not responsible for what she did. The disadvantage of the new terminology is that the class of those who oppose compatibilism includes both "hard determinists" and the "libertarians" – those who believe people are determined and therefore unfree, and those who believe they are undetermined and therefore free. "Soft determinism" has fallen into some desuetude, however, and is generally replaced in the literature with "compatibilism", the name for the thesis that freedom and determinism are compatible.
