Abstract
Hume’s division of perceptions into simple and complex has been criticized for being vague and perfunctory. Often the division is considered to be a rather weak part of his system, yet there is no agreement on its particular shortcomings and no consensus that it is totally impracticable. At the same time, the division between simple and complex perceptions has not attracted strong interest or attention from commentators. Most accounts consist of short paraphrases, some of which suggest a connection with Locke. The few attempts at a systematic explanation include the accounts of Baier, Frasca-Spada, Garrett, Pears, and Waxman.
