This volume, the thirty-fifth year of published proceedings, contains five papers and commentaries presented to the Boston Area Colloquium in Ancient Philosophy during the academic year 2018-19. Paper topics include: evidence for Simplicius as author of the Commentary on the
De Anima
; Aristotle and Humean theory of motivation, ‘besires’ and desires; moderation in NE 3,10-12 as novel in Aristotle, differing greatly from his contemporaries, especially Plato’s
Charmides
; Platonic memory and oblivion, mythic sources and cultural influence; Aristotle’s final causality in recovering nature from inanimate mechanism. The commentators take up the themes of these papers, in some instances developing and building on the main argument, while in others offering direct challenges to the principal author’s thesis.
