In the early to mid 20th-century, Martin Heidegger brought renewed attention to the concept of aletheia, by relating it to the notion of disclosure, or the way in which things appear as entities in the world. While he initially referred to aletheia as "truth", specifically a form that is pre-Socratic in origin, Heidegger eventually corrected this interpretation, writing:
To raise the question of aletheia, of disclosure as such, is not the same as raising the question of truth. For this reason, it was inadequate and misleading to call aletheia, in the sense of opening, truth.
