  Aristotle’s “elenctic refutation” has been fruitfully compared to a Kantian transcendental argument. Transcendental arguments generally run as follows: If certain aspects of experience or thinking are possible, the world must be a certain way. Since these aspects of experience or thinking do exist, the world is a certain way. These aspects of our experience or thinking presuppose that the world is a certain way. That the world is a certain way explains these aspects of our experience or thinking and not the other way round. On this interpretation, Aristotle would be arguing that the world conforms to PNC, or that PNC is true, because it is presupposed by and explains the opponent’s ability to say something significant.
