Professor Crowell's main field of interest is twentieth century European philosophy, especially phenomenology (the philosophy of Edmund Husserl) and its development in Heidegger, existentialism (Sartre, Merelau-Ponty, Levinas, Arendt), hermeneutics (Gadamer, Ricoeur) and post-structuralism (Derrida, Lyotard). My systematic interests lie in metaphysics, meta-ethics, philosophy of mind, aesthetics, and the philosophy of history. He also does research in the 18th and 19th century background of contemporary European thought: Kant, German Idealism, Nietzsche, Kierkegaard, and the German neo-Kantians.
