Phenomenology Heidegger's mentor
Edmund Husserl developed a method of analysis called "
phenomenological reduction" or "bracketing," that emphasized primordial experience as its key element. Husserl used this method to define the structures of consciousness and show how they are directed at both real and ideal objects within the world.
Being and Time employs this method but purportedly modifies Husserl's subjectivist tendencies. Whereas Husserl conceived humans as constituted by consciousness, Heidegger countered that consciousness is peripheral to
Dasein, which cannot be reduced to consciousness. Consciousness is thus an "effect" rather than a determinant of existence. By shifting the priority from consciousness (psychology) to existence (ontology), Heidegger altered the subsequent direction of phenomenology. But
Being and Time misrepresented its phenomenology as a departure from methods established earlier by Husserl, according to
Daniel O. Dahlstrom. In this vein, Robert J. Dostal asserts that "if we do not see how much it is the case that Husserlian phenomenology provides the framework for Heidegger's approach," then it's impossible to exactly understand
Being and Time. On publication in 1927,
Being and Time bore a dedication to Husserl, who beginning a decade earlier, championed Heidegger's work, and helped him secure the retiring Husserl's chair in Philosophy at the
University of Freiburg in 1928. Because Husserl was Jewish, in 1941 Heidegger, then a member of the
Nazi Party, agreed to remove the dedication from
Being and Time (restored in 1953 edition).
Hermeneutics Being and Time employed the "
hermeneutic circle" as a method of analysis or structure for ideas. According to Susann M. Laverty (2003), Heidegger's circle moves from the parts of experience to the whole of experience and back and forth again and again to increase the depth of engagement and understanding. Laverty writes (
Kvale 1996), "This spiraling through a hermeneutic circle ends when one has reached a place of sensible meaning, free of inner contradictions, for the moment." The hermeneutic circle and certain theories concerning history in
Being and Time are acknowledged within the text to rely on the writings of
Wilhelm Dilthey. The technique was later employed in the writings of
Jürgen Habermas, per "Influence and reception" below.
Destructuring In
Being and Time Heidegger briefly refutes the philosophy of
René Descartes (in an exercise he called "destructuring"), but the second volume, intended as a
Destruktion of Western philosophy, was never written. Heidegger sought to explain how theoretical knowledge came to be seen, incorrectly in his view, as fundamental to being. This explanation takes the form of a destructuring (
Destruktion) of the philosophical tradition, an interpretative strategy that reveals the fundamental experience of being hidden within the theoretical attitude of the
metaphysics of presence. In later works, while becoming less systematic and more obscure than in
Being and Time, Heidegger turns to the exegesis of historical texts, especially those of Presocratic philosophers, but also of Aristotle, Kant,
Hegel,
Plato,
Nietzsche, and
Hölderlin, among others. ==Influence and reception==
