Studies in Phenomenology and Existential Philosophy

Heidegger's lecture course at the University of Marburg in the summer of 1925, an early version of Being and Time (1927), offers a unique glimpse into the motivations that prompted the writing of this great philosopher's master work and the presuppositions that gave shape to it. The book embarks upon a provisional description of what Heidegger calls "Dasein," the field in which both being and time become manifest. Heidegger analyzes Dasein in its everydayness in a deepening sequence of terms: being-in-the-world, worldhood, and care as the being of Dasein. The course ends by sketching the themes of death and conscience and their relevance to an ontology that makes the phenomenon of time central. Theodore Kisiel's outstanding translation premits English-speaking readers to appreciate the central importance of this text in the development of Heidegger's thought.

The text of Martin Heidegger's 1930-1931 lecture course on Hegel's Phenomenology of Spirit contains some of Heidegger's most crucial statements about temporality, ontological difference and dialectic, and being and time in Hegel. Within the context of Heidegger's project of reinterpreting Western thought through its central figures, Heidegger takes up a fundamental concern of Being and Time, "a dismantling of the history of ontology with the problematic of temporality as a clue." He shows that temporality is centrally involved in the movement of thinking called phenomenology of spirit.
