Wheeler, Michael (12. 10. 2011). „Martin Heidegger – 3.1 The Turn and the Contributions to Philosophy”. Stanford Encyclopedia of Philosophy. Приступљено 2013-05-22. „In a 1947 piece, in which Heidegger distances his views from Sartre's existentialism, he links the turn to his own failure to produce the missing divisions of Being and Time [i.e., "Time and Being"]. ... At root Heidegger's later philosophy shares the deep concerns of Being and Time, in that it is driven by the same preoccupation with Being and our relationship with it that propelled the earlier work. ... [T]he later Heidegger does seem to think that his earlier focus on Dasein bears the stain of a subjectivity that ultimately blocks the path to an understanding of Being. This is not to say that the later thinking turns away altogether from the project of transcendental hermeneutic phenomenology. The project of illuminating the a priori conditions on the basis of which entities show up as intelligible to us is still at the heart of things.”CS1 одржавање: Формат датума (веза)
"The opposition of world and earth is a strife." (Heidegger (1971), Poetry, Language, Thought, translation and introduction by Albert Hofstadter, p. 47: translation corrected by Hubert Dreyfus; original German: "Das Gegeneinander von Welt und Erde ist ein Streit.") The two interconnected dimensions of intelligibility (revealing and concealing) are called "world" and "earth" by Heidegger, the latter informing and sustaining the former (Heidegger's Aesthetics (Stanford Encyclopedia of Philosophy)).
