 The six books entitled Against those in the Disciplines (M 1–6) have traditionally received less attention. Only in the last few years have scholars begun to explore them with the kind of philosophical subtlety that has been brought to bear in the study of ancient skepticism in recent decades. M 1–6 skeptically examine six fields of study, namely grammar, rhetoric, geometry, arithmetic, astronomy, and music-theory. Sextus begins with an astonishing move. Contrary to his usual strategy of emphasizing the distance between skeptics and dogmatists, he admits that Pyrrhonians and Epicureans share much in viewing standard disciplines as useless (M 1.1–7; cf. Thorsrud 2019). Generally speaking, increased attention to M 1–6 may provide additional occasion to modify the long-standing assumption that the Stoics are Sextus’ most important dogmatic interlocutors. Throughout M 1–6, resonances between Epicurean and Pyrrhonian philosophy are remarkably visible (Bett 2018, “Introduction”). Engagement with Epicurean philosophy shapes Sextus’ approach deeply, to the extent that both schools, Stoics and Epicureans, should be considered fundamental points of reference.
