When Aristotle treats true and false statements in his logical treatises, he shows that truth and falsity are the pre-supposed, non-discursive grounding for statements themselves. His ethical treatises show that intellectual virtues are constituted by truth. The Metaphysics shows that truth in thinking is sustained by the truth of being. All these diverse studies can be connected to one another by way of the Greek term for truth, aletheia, as Heidegger has treated it.
