 Because of these ethical excellences, skeptics held themselves up as wise men. The more radical Pyrrhonian Skeptics, who doubted the truth of all claims, quickly ran afoul of the following objection, which has been given in various forms throughout the history of philosophy: a thoroughgoing skeptic, it seems, cannot live his or her skepticism. If one doubts (and thus fails to act) on the truth of such claims as “Food is necessary for human life”, it would follow that one could not live at all. Academic Skeptics attempted to avoid this objection by arguing that though skepticism precluded living by the truth, since the truth could not be known, nevertheless one could live by the truthlike or plausible. Hence theirs was a more practical version of skepticism.
