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 Concept of Time presents Heidegger's so-called Dilthey review, widely considered the first draft of his celebrated masterpiece, Being and Time. Here Heidegger reveals his deep commitment to Wilhelm Dilthey and Count Yorck von Wartenburg. He agrees with them that historicity must be at the centre of the new philosophy to come. However, he also argues for an ontological approach to history. From this ontological turn he develops the so-called categories of Dasein. This work demonstrates Heidegger's indebtedness to Yorck and Dilthey and gives further evidence to the view that thought about history is the germ cell of Being and Time. However, it also shows that Heidegger's commitment to Dilthey was not without reservations and that his analysis of Dasein actually employs Husserl's phenomenology. The work reopens the question of history in a broader sense, as Heidegger struggles to thematize history without aligning it with world-historical events. The text also provides a concise and readable summary of the main themes of Being and Time and as such is an ideal companion to that text.

A view of Heidegger's divergence from the traditional philosophies of reason.

The First Conference of the International Society for the Study of Time was held at the Mathematisches Forschungsinstitut at Oberwolfach in the Black Forest, Federal Republic of Germany from Sunday, 31 August to Saturday, 6 September, 1969. The origin of this conference and the formation of the Society goes back to a proposal due to J. T. Fraser that was discussed at a conference on "Interdisciplinary Perspectives of Time" held by the New York Academy of Sciences in January, 1966. It was unanimously agreed than that an international society should be formed on an interdisciplinary basis with the object of stimulating interest in all problems concerning 'time and that this object could best be attained by means of conferences held at regular intervals. J. T. Fraser was elected Secretary, S. Watanabe Treasurer, and I was elected President. It was agreed, at my suggestion, that the organization of the first conference of the newly formed Society be left to a committee of these three officers, on the understanding that they would invite authorities on the role of time in the various special sciences and humanities to form an Advisory Board to assist them. One of the main difficulties in seeking support for an interdisciplinary conference is that most foundations confine their interest exclusively either to the sciences or to the humanities.

"What is the meaning of being?" This is the central question of Martin Heidegger's profoundly important work, in which the great philosopher seeks to explain the basic problems of existence. A central influence on later philosophy, literature, art, and criticism—as well as existentialism and much of postmodern thought—Being and Time forever changed the intellectual map of the modern world. As Richard Rorty wrote in the New York Times Book Review, "You cannot read most of the important thinkers of recent times without taking Heidegger's thought into account." This first paperback edition of John Macquarrie and Edward Robinson's definitive translation also features a new foreword by Heidegger scholar Taylor Carman.
