The article on Dilemma of determinism is not mine, it seems to have been written by somebody knowledgeable in philosophy or at least somebody who read a lot of books on the topic. I prefer another version thereof: . Please note that both the Hume's passes and the James' lecture were precisely on this topic (analysing of human freedom in terms of necessity and chance and discussing the argument of whether there can be any freedom when using such dichotomy; such chance/necessity analysis was also done by Schopenhauer and the argument was used by many modern philosophers, see the archival article from my link).
