The first part of the article discusses the conditions under which the “school” of thought known as “philosophical anthropology” arose and the relevance today of the problems it posed, concluding with a look at the recent prevalence taken by biological research. The second part examines the conceptions advanced by its leading figures, Max Scheler, Helmuth Plessner and Arnold Gehlen, and shows how each of them contributed to a “sociologization of anthropological knowledge.” On the basis of this analysis, philosophical anthropology proves (...) itself capable of making a significant contribution to an interdisciplinary understanding of the conditions of human life and to reflection on the foundations of sociological research and social theory.
