“Empirical statements that claim truth depend upon evidence; statements that claim truthfulness depend upon our acceptance of them. My acceptance is the way I respond to them, and not everyone is capable of the response, or willing for it. I put this by saying that a true statement is something we know or do not know; a truthful statement is one we must acknowledge or fail or refuse to acknowledge.”
Stanley Cavell, 1971, The World Viewed: Reflections on the Ontology of Film.
