U Hajdegerovom fundamentalnom tekstu Biće i vreme (1927), „Dazajn“ je predstavljen kao termin za određeni tip bića koju ljudi poseduju.[15] Dazajn je prevedeno kao „biti tamo“. Hajdeger veruje da Dazajn već ima „predontološko“ i neapstraktno razumevanje koje oblikuje način na koji živi. Ovaj način postojanja on naziva „biti u svetu“. Komentatori su primetili da su Dazajn i „biti u svetu“ jedinični koncepti u kontrastu sa gledištem na „subjekt/objekat“ racionalističke filozofije još od vremena Renea Dekarta. Hajdeger koristi analizu Dazajna da pristupi pitanju značenja bića, koje Hajdegerski učenjak Majkl Viler opisuje kao „zabrinutost zbog onoga što čini biće razumnim kao bića“.[16]
Hajdegerov kasniji rad obuhvata kritiku stanovišta, uobičajenog u zapadnoj tradiciji, da je cela priroda „stalni rezervat“, kao da je deo industrijskog inventara.[17][18]
Hajdeger je bio član i podržavao nacističku stranku.[19][20] Postoje kontroverze oko odnosa između njegove filozofije i njegovog nacizma.[21][22]
Život
Kuća u Meskirhu, u kojoj je Hajdeger odrastaoGrob Martina Hajdegera
Veliki uspeh knjige „Biće i vreme“ omogućio je Hajdegeru da postane profesor u Frajburgu. Predavao je filozofiju sve do penzionisanja 1945. Penzionisale su ga francuske okupacione vlasti, zbog poznatog rektorskog govora u vreme dolaska nacista na vlast, u kome je slavio "Istorijski poziv Nemačke...". Ostatak života proveo je povučeno u planinskoj kući na padinama Crne šume, ispod Švarcvalda. Hajdeger se smatra jednim od najuticajnijih filozofa 20. veka. Posebno je značajan njegov uticaj u kontinentalnoj filozofskoj tradiciji (posebno na Žan Pola Sartra) a takođe je uticao na istaknutog rimokatoličkog teologaKarla Ranera.
Posle dolaska Hitlera na vlast 1933. godine Hajdeger se učlanjuje u nacionalsocijalističku partiju i biva izabran za rektora Univerziteta u Frajburgu. Te godine drži i poznati rektorski govor u kome govori o pozivu nemačkih univerziteta u novom vremenu. Njegova karijera se međutim zbog neslaganja sa nacistima završava već 1934. godine. Ostaje učlanjen u nacionalsocijalističku partiju sve do završetka rata. Zbog svega ovoga francuske okupacione vlasti mu brane da predaje na univerzitetu sve do 1951. godine kada nastavlja i zadržava se na redovnim studijama sve do 1967.

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)

(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)).
