The leading philosopher of the Scottish Enlightenment, David Hume, is the subject of this program. In it, expert John Passmore of the National Australian University discusses causality as the cornerstone of Hume's philosophy. Also discussed are three of Hume's basic philosophical views:anything that is not a fact, is illusion; judgments on fact mist be based on concrete experience; and all knowledge is imperfect. Hume also denies the idea of a continuous identical self, refutes deism, and views reason as a slave to passion.
