““Within certain limits terminology is always arbitrary. But the definition of being-true as unveiling, making manifest, is not an arbitrary, private invention of mine; it only gives expression to the understanding of the phenomenon of truth, as the Greeks already understood it in a pre-scientific as well as philosophical understanding, even if not in every respect in an originally explicit way. Plato already says explicitly that the function of logos, of assertion, is deloun, making plain, or as Aristotle says more exactly with regard to the Greek expression of truth: aletheuein. Lanthanein means to be concealed: a- is the privative, so that a-letheuein is equivalent to: to pluck something out of its concealment, to make manifest or reveal. For the Greeks truth means: to take out of concealment, uncovering, unveiling.””
