The New School for Social Research continues the Graduate Faculty's tradition of synthesizing leftist American intellectual thought and critical European philosophy. True to its origin and its firm roots within the University in Exile, The New School for Social Research, particularly its Department of Philosophy, is in the minority in the United States in offering students thorough training in the modern continental European philosophical tradition known as "Continental philosophy". Thus, it stresses the teachings of Parmenides, Aristotle, Leibniz, Spinoza, Hume, Kant, Hegel, Kierkegaard, Marx, Nietzsche, Husserl, Heidegger, Arendt, Freud, Benjamin, Wittgenstein, Foucault, Derrida, Deleuze, et al. The thought of the Critical Theory of the Frankfurt School: Max Horkheimer, Walter Benjamin, Theodor Adorno, Herbert Marcuse, Jürgen Habermas, et al. holds an especially strong influence on all divisions of the school. After the death of Hannah Arendt in 1975, the philosophy department revolved around Reiner Schürmann and Ágnes Heller.
