This paper summarizes David Hume's views on the philosophical problems of causation and inductive reasoning. A skeptic, he argued against taking for granted cause and effect relationships as well as induction. The paper points out the reliance of the physical sciences on induction and Hume's philosophical separation of cause from effect, as well as the importance of the necessity relation, and concludes that, although hard to stomach, Hume's skepticism is a necessary component of our philosophical explorations. 3 pgs.
