    A Puzzle in Stoic Ethics
    Oxford Studies in Ancient Philosophy 24 303-40. 2003.

This history suggests that the sceptics resemble Plato in lacking the ‘non-epistemic’ or ‘non-doxastic’ conception of appearance developed by Aristotle and the Stoics. What is distinctive about the Pyrrhonian sce…Read more
