This volume, the 36th year of published proceedings, contains five papers and four commentaries presented to the Boston Area Colloquium in Ancient Philosophy during the academic year 2019–20. Paper topics: On Platonism, how Plato’s Cave preserves his political interest from Arendt’s critique, and how Plutarch’s Isis and Osiris uses a complex framing device to integrate Platonic metaphysics and politics. On Aristotle, that dialectic is a versatile techne for formal and informal discussion, and the role of practice to preserve the voluntary nature of character despite its grounding in upbringing. Finally, using Aristotle to argue for the legitimacy of anger against transhumanist efforts, echoing Stoic concerns against such emotions. The comments challenge or sustain the theses presented in the main papers.-
