Martin Heidegger's Contributions to Philosophy reflects his famous philosophical "turning." In this work, Heidegger returns to the question of being from its inception in Being and Time to a new questioning of being as event. Heidegger opens up the essential dimensions of his thinking on the historicality of being that underlies all of his later writings. Contributions was composed as a series of private ponderings that were not originally intended for publication. They are nonlinear and radically at odds with the traditional understanding of thinking. This translation presents Heidegger in plain and straightforward terms, allowing surer access to this new turn in Heidegger's conception of being.
