In this book Pierre Keller examines Husserl's and Heidegger's approaches to fundamental elements of human experience, and shows both how their conceptions are related to each other and how they fit into a wider philosophical context. His sophisticated and accessible account of the phenomenological philosophy of Husserl and the existential phenomenology of Heidegger will be of wide interest to students and specialists in these areas, while analytic philosophers of mind will be interested in the detailed parallels that he draws with a number of concerns of the analytic philosophical tradition.
