The Time of Life: Heidegger and Ethos (SUNY Series in Contemporary Continental Philosophy)

William McNeill

Throughout his Marburg and Freiburg lecture courses of the 1920s,
as in his magnum opus Being and Time (1927), Heidegger never
ceased to emphasize the central importance of the phenomenon of
world—a phenomenon that, he claimed, had never been adequately
appreciated or understood in the history of philosophy, if indeed
it had been seen at all.
