  Other philosophers take this common meaning to be secondary and derivative. According to Martin Heidegger, the original meaning and essence of truth in Ancient Greece was unconcealment, or the revealing or bringing of what was previously hidden into the open, as indicated by the original Greek term for truth, aletheia. On this view, the conception of truth as correctness is a later derivation from the concept's original essence, a development Heidegger traces to the Latin term veritas. Owing to the primacy of ontology in Heidegger's philosophy, he considered this truth to lie within Being itself, and already in Being and Time (1927) had identified truth with " being-truth " or the "truth of Being" and partially with the Kantian thing-in-itself in an epistemology essentially concerning a mode of Dasein.
