Martin Heidegger - Overview

Overview

Heidegger claimed that Western philosophy since Plato has misunderstood what it means for something "to be", tending to approach this question in terms of a being, rather than asking about Being itself. In other words, Heidegger believed all investigations of being have historically focused on particular entities and their properties, or have treated Being itself as an entity, or substance, with properties. A more authentic analysis of being would, for Heidegger, investigate "that on the basis of which beings are already understood," or that which underlies all particular entities and allows them to show up as entities in the first place (see world disclosure). But since philosophers and scientists have overlooked the more basic, pre-theoretical ways of being from which their theories derive, and since they have incorrectly applied those theories universally, they have confused our understanding of being and human existence. To avoid these deep-rooted misconceptions, Heidegger believed philosophical inquiry must be conducted in a new way, through a process of retracing the steps of the history of philosophy.

Heidegger argued that this misunderstanding, beginning with Plato, has left its traces in every stage of Western thought. All that we understand, from the way we speak to our notions of "common sense", is susceptible to error, to fundamental mistakes about the nature of being. These mistakes filter into the terms through which being is articulated in the history of philosophy—such as reality, logic, God, consciousness, and presence. In his later philosophy, Heidegger argues that this profoundly affects the way in which human beings relate to modern technology.

The Internet Encyclopedia of Philosophy states that his writing is 'notoriously difficult', possibly because his thinking was 'original' and clearly on obscure and innovative topics. Heidegger accepted this charge, stating 'Making itself intelligible is suicide for philosophy', and suggesting that intelligibility is what he is critically trying to examine.

Heidegger's work has strongly influenced philosophy, aesthetics of literature, and the humanities. Within philosophy it played a crucial role in the development of existentialism, hermeneutics, deconstructionism, postmodernism, and continental philosophy in general. Well-known philosophers such as Karl Jaspers, Leo Strauss, Ahmad Fardid, Hans-Georg Gadamer, Jean-Paul Sartre, Emmanuel Lévinas, Hannah Arendt, Maurice Merleau-Ponty, Michel Foucault, Richard Rorty, William E. Connolly, and Jacques Derrida have all analyzed Heidegger's work.

Heidegger supported National Socialism in 1933 and was a member of the Nazi Party until May 1945,. His defenders, notably Hannah Arendt, see this support as arguably a personal " 'error' " (a word which Arendt placed in quotation marks when referring to Heidegger's Nazi-era politics). Defenders think this error was irrelevant to Heidegger's philosophy. Critics, such as Emmanuel Levinas and Karl Löwith, claim that Heidegger's support for National Socialism revealed flaws inherent in his thought.
