Without Martin Heidegger's "Being and Time" from 1927, neither the philosophy of the 20th century nor the contemporary philosophical discourse can be understood. How did his innovative approach to the world and human existence, his new understanding of time and history, care and death, everyday life and understanding, as well as his fundamental critique of traditional ontology and the philosophy of consciousness, inspire the first generation of students to groundbreaking ideas? Why did the work remain a fragment? How did it still enable receptions that have made a significant impact up to the present day? How could the work exert its profound effects on both Protestant and Catholic theology, psychology, and literary studies? Finally, how does Heidegger's later thinking relate to "Being and Time"? The unique intermediary position of "Being and Time" between ontology and transcendence.
