²⁷The Pyrrhonians explicitly advocated rejecting any valences (Sextus Empiricus’s Outlines of Pyrrhonism, 1.27-28). If you admit that you’re not sure about what category some object belongs to, valences as well as any further associations and generalizations have to be given up as well. This implies further processes that are more specific to categories, and complement the logic of simple perceptual uncertainty.
