Abstract

In this article I consider Sextus’ account of the Five Modes and of the Two Modes in his Outlines of Pyrrhonism. I suggest that from these we can derive the basic form of a number of different problems which I refer to as “Agrippan problems,” where this category includes both the epistemic regress problem and the problem of the criterion. Finally, I suggest that there is a distinctive Agrippan problem present at the beginning of Hegel’s Science of Logic.
