 “I do not know even this one thing, namely that I know nothing”, is the opening sentence of the treatise (TNK: 172). Sanches, next considers whether this is a paradoxical or contradictory principle of scepticism. For if you know how to establish that you do not know anything, it follows that you already know something. Furthermore, he argues, if you “have understood the ambiguity of the inference, you have clearly perceived that nothing is known” (TNK: 173). And nothing is known, clearly because such ambiguities only point to the fact that language does not give us access to absolute knowledge. Dialectical, logical, and linguistic entanglements such as the one mentioned above only proves his point. Thus in an allusion to Aristotle’s Metaphysics (995a30), he asks his reader to help him “untie this knot” (TNK: 173). This marks the beginning of his critique of Aristotelian nominalism.
