Edmund Husserl was a German philosopher who founded phenomenology — one of the most influential philosophical movements of the twentieth century. Dissatisfied with the prevailing psychologism in philosophy of logic, Husserl sought to develop a rigorous science of consciousness by describing the essential structures of experience. His method of epoché — suspending assumptions about the external world in order to examine the pure flow of consciousness — and his concepts of intentionality and the life-world provided the vocabulary and methods that shaped Heidegger, Sartre, and Merleau-Ponty.
