Under “David Hume”, the Stanford Encyclopedia of Philosophy begins with, “The most important philosopher ever to write in English”. His most formidable contemporary critic was the fellow Scot, Thomas Reid, the major architect of so-called Scottish Common Sense Philosophy. The most significant features of Hume’s work, as understood by Reid, are the representive theory of perception, the nature of causation and causal concepts, the nature of personal identity and the foundations of morality. Each of these topics is presented in a pair of lectures, the first summarizing Hume’s position and the second Reid’s critique of that position.
