Abstract

In the newly discovered letter Hume answers Reid's charge that he held a theory of ideas derived from his predecessors and criticizes Reid's own theory of innate ideas. He defends his own theory that ideas are derived from impressions. I discuss Reid's own puzzlement that in the first _Enquiry_ Hume ascribes a natural belief in necessary connections to the vulgar without an idea--and its influence on subsequent readings of Hume as a 'regularity theorist.' I argue that it was the 'Common Sense' school of philosophers following Reid, rather than Hume, who insisted that beliefs must be based on legitimate ideas.
