Abstract

Ancient sceptics, unlike their modern counterparts, claim to live their scepticism. Nowadays scepticism, whether epistemological, moral, or of any other variety, is seen as a purely theoretical position, with no direct bearing on the actual living of one’s life; this is because philosophical theories and everyday attitudes are taken to be in some way “insulated” from one another. Serious questions may be raised about the character of this alleged “insulation,” but these are not my present concern; the fact is that no such split between “the philosophical” and “the ordinary” was entertained in the ancient world. It follows that the viability of scepticism as a way of life is a crucial issue for ancient sceptics. It is no accident that one of the most enduring objections to ancient scepticism is to the effect that the sceptical attitude—that is, the posture of universal suspension of judgement—is incompatible with any kind of normal human action; this was known in antiquity as the charge of apraxia, “inaction.” The sceptics for their part, were just as persistent in arguing that suspension of judgement had no such damaging consequences. In as much as the assessment of actual or imaginable types of human life is the province of ethics, I take this debate between ancient sceptics and their detractors to be, in a broad sense, an ethical debate.
