  (For a slightly different take on what Sextus is up to in PH I 12, see Cooper 2012, who interprets Sextus as telling us about his ‘original skeptic predecessors’ (283) or ‘proto-skeptics’ (285), who came upon the skeptical skill as a result of their reflections, ‘as something then for later worriers to avail themselves of’ (282 n.76). In other words, Sextus is primarily offering ‘a narrative history of the experiences of those who became the first to practice the skeptic philosophy’ (288), rather than an account of how anyone at any time might find themselves becoming a skeptic.)
