Sextus Empiricus Pyrrhoniae Hypotyposes 3.7.54

[54] But if reason is a body, inasmuch as about bodies also there is much controversy as to whether or not they are apprehended, owing to what is called their ‟continual flux,” ¹ which gives rise to the view that they do not admit of the title ‟this” and are non- existent—just as Plato ² speaks of bodies as ‟becoming but never being,”—I am perplexed as to how this controversy about Body is to be settled, as I see that it cannot be settled, because of the difficulties stated a moment ago, either by a body or by an incorporeal. Neither, then, is it possible to apprehend the incorporeals by reason.
