Martin Heidegger is one of the twentieth century's most important philosophers, and now also one of the most contentious as revelations of the extent of his Nazism continue to surface. His ground-breaking works have had a hugely significant impact on contemporary thought through their reception, appropriation and critique. His thought has influenced philosophers as diverse as Sartre, Merleau-Ponty, Arendt, Adorno, Gadamer, Levinas, Derrida and Foucault, among others. In addition to his formative role in philosophical movements such as phenomenology, hermeneutics and existentialism, structuralism and post-structuralism, deconstruction and post-modernism, Heidegger has had a transformative effect on diverse fields of inquiry including political theory, literary criticism, theology, gender theory, technology and environmental studies.
