Offering a full-scale study of the theory of reality hidden beneath modern logic, The Metaphysical Foundations of Logic, a lecture course given in 1928, illuminates the transitional phase in Heidegger's thought from the existential analysis of Being and Time to the overcoming of metaphysics in his later philosophy. In a searching exposition of the metaphysical problems underpinning Leibniz's theory of logical judgment, Heidegger establishes that a given theory of logic is rooted in a certain conception of Being. He explores the significance of Western logic as a system-building technical...

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...

The Principle of Reason, the text of an important and influential lecture course that Martin Heidegger gave in 1955 56, takes as its focal point Leibniz s principle: nothing is without reason. Heidegger shows here that the principle of reason is in fact a principle of being. Much of his discussion is aimed at bringing his readers to the "leap of thinking," which enables them to grasp the principle of reason as a principle of being. This text presents Heidegger's most extensive reflection on the notion of history and its essence, the Geschick of being, which is considered on of the most...

This book, the text of Martin Heidegger's lecture course of 1929/30, is crucial for an understanding of Heidegger's transition from the major work of his early years, Being and Time, to his later preoccupations with language, truth, and history. First published in German in 1983 as volume 29/30 of Heidegger s collected works, The Fundamental Concepts of Metaphysics presents an extended treatment of the history of metaphysics and an elaboration of a philosophy of life and nature. Heidegger s concepts of organism, animal behavior, and environment are uniquely developed and defined with...

This volume reconstructs Martin Heidegger's lecture course at the University of Marburg in the winter semester of 1924-25, which was devoted to an interpretation of Plato and Aristotle. Published for the first time in German in 1992 as volume 19 of Heidegger's Collected Works, it is a major text not only because of its intrinsic importance as an interpretation of the Greek thinkers, but also because of its close, complementary relationship to Being and Time, composed in the same period. In Plato's Sophist, Heidegger approaches Plato through Aristotle, devoting the first part of the...

Martin Heidegger's 1942 lecture course interprets Friedrich Holderlin's hymn "The Ister" within the context of Holderlin's poetic and philosophical work, with particular emphasis on Holderlin's dialogue with Greek tragedy. Delivered in summer 1942 at the University of Freiburg, this course was first published in German in 1984 as volume 53 of Heidegger's Collected Works. Revealing for Heidegger's thought of the period are his discussions of the meaning of "the political" and "the national," in which he emphasizes the difficulty and the necessity of finding "one's own" in and through a...

"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."

Volume 18 of Martin Heidegger's collected works presents his important 1924 Marburg lectures which anticipate much of the revolutionary thinking that he subsequently articulated in Being and Time. Here are the seeds of the ideas that would become Heidegger's unique phenomenology. Heidegger interprets Aristotle's Rhetoric and looks closely at the Greek notion of pathos. These lectures offer special insight into the development of his concepts of care and concern, being-at-hand, being-in-the-world, and attunement, which were later elaborated in Being and Time. Available in English for the...
