Marc Richir (1943-2015) is one of the most authoritative phenomenologists of his generation with disciples all over the world. His importance, which has become increasingly evident in recent years, derives from his emphasizing of the imagination and fantasy in their symbolic function. In this way he opens up phenomenology to adopt perspectives that are no less interesting for artists than for poets or musicians. But his spectrum is even more extensive. As a trained physicist, Richir turned to problems of natural philosophy; at the same time, he was an excellent expert in structuralism, anthropology and psychoanalysis. But he was also very familiar with Classical German Philosophy, no less than with the thinking of the founding fathers of phenomenology, as well as with the influential approaches of Merleau-Ponty and Derrida. This book is the first monograph in the German language to present Richir's extensive work in all its scope. The question of a "phenomenological metaphysics" provides the guideline to testify to the openness of recent phenomenology to these wide-ranging topics.
