 Following Frede, several scholars focus on PH 1.13 when discussing skeptical belief (with the notable exceptions of Barnes 1980 [1997] and Barney 1992). They take it to be obvious that, in this paragraph, Sextus distinguishes between two kinds of belief, one which he bans from the skeptic’s life, and one which he allows into the skeptic’s life. Barnes (1982 [1997]) employs a distinction between rustic and urbane skepticism. The rustic skeptic suspends on all matters. The urbane skeptic suspends on scientific matters, but holds ordinary beliefs. The clause “non-evident matters investigated in the sciences” in PH 1.13 might be taken as a point of reference for the urbane interpretation. However, Barnes points out that this cannot be right. Everything can be considered as a non-evident matter, even such things as whether honey is sweet.
