Sextus Empiricus Pyrrhoniae Hypotyposes 2.5.28

[28] For when Plato ¹ declares that ‟Man is a featherless two-footed animal with broad nails, receptive of political science,” not even he himself claims to affirm this positively; for if Man is one of the class of things which, as he puts it, ² come into being but never possess absolute being, and if it is impossible, in his view, to make a positive declaration about things which never really exist, then even Plato will not claim to be taken as putting forward this definition positively, but rather as making, in his usual way, a probable statement.
