[5] 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.
Instead, Heidegger focused on the elucidation of how an ontological "world" is disclosed, or opened up, in which things are made intelligible for human beings in the first place, as part of a holistically structured background of meaning.
Heidegger began his discourse on the reappropriation of aletheia in his magnum opus, Being and Time (1927),[8] and expanded on the concept in his Introduction to Metaphysics.
[9] For more on his understanding of aletheia, see Poetry, Language, Thought,[10] in particular the essay entitled The Origin of the Work of Art, which describes the value of the work of art as a means to open a "clearing" for the appearance of things in the world, or to disclose their meaning for human beings.
[11] Heidegger revised his views on aletheia as truth, after nearly forty years, in the essay "The End of Philosophy and the Task of Thinking," in On Time and Being.
