What is Phenomenology?
Pierre Thévenaz
Quadrangle Books
During the past fifty years phenomenology, as a radical philosophy of experience and as the method of a new existentialism, has become the dominant philosophical force in Western Europe. It has provided the theoretical foundation for new approaches and new methods in nearly all the human sciences. Psychology,
psychiatry, the social studies- all have been profoundly affected by this renewal. Though this revolution is already far advanced in Europe, it is only now beginning to make itself felt in England
and America.
This book contains four of Pierre Thevenaz' most important essays on phenomenology. Thevenaz was a Swiss philosopher well known for his numerous writings on phenomenology, on the history of philosophy, and on "Protestant philosophy." He diedin 1955 at the age of 42. 
Within the new, typically 20th-century intellectual outlook it represents, phenomenology has given birth to a proliferating family of new and original philosophical currents. This bookprovides a guideline through the complex skein of contemporary phenomenological thought. It stresses the fundamental unity of the movement and shows the essential continuity that binds the existential philosophies of Heidegger, Sartre, and Merleau-Ponty to the original phenomenological method elaborated by Edmund Husserl at the beginning of the century.
