Abstract

Heidegger’s main interest was ontology or the study of being. In his fundamental treatise, Being and Time, he attempted to access being (Sein) by means of phenomenological analysis of human existence (Dasein) in respect to its temporal and historical character. After the change of his thinking (“the turn”), Heidegger placed an emphasis on language as the vehicle through which the question of being can be unfolded. He turned to the exegesis of historical texts, especially of the Presocratics, but also of Kant, Hegel, Nietzsche and Hölderlin, and to poetry, architecture, technology, and other subjects. Instead of looking for a full clarification of the meaning of being, he tried to pursue a kind of thinking which was no longer “metaphysical.” He criticized the tradition of Western philosophy, which he regarded as nihilistic, for, as he claimed, the question of being as such was obliterated in it. He also stressed the nihilism of modern technological culture. By going to the Presocratic beginning of Western thought, he wanted to repeat the early Greek experience of being, so that the West could turn away from the dead end of nihilism and begin anew. His writings are notoriously difficult. Being and Time remains his most influential work.
