Doug,
thanks, this makes more sense and is very helpful. I still have the nagging sense that the Pyrrhonists want their cake and eat it too.
And I’m not alone. I’m reading now a scholarly essay by Tad Brennan and Cliff Roberts (in: Skepticism — From Antiquity to the Present, ed. by Diego Machuca and Baron Reed) which goes into very diverging interpretations of what exactly the Pyrrhonists (specifically Sextus) were saying and whether it was coherent or not.
Still trying to learn. And please don’t get the impression I dislike Pyrrhonism. It’s not my favorite kind of Skepticism, but I think Skepticism as a whole is better than all the other schools, including Stoicism.
