Almost a hundred years later, Jos de Mul has edited a collection of 26 new essays on Plessner’s text, entitled Plessner’s Philosophical Anthropology: Perspectives and Prospects. The volume offers a variety of advanced discussions of its theme. In this review essay of De Mul’s collection, I provide a critical overview of the contents of the new volume and some speculations on the possible motives and future directions of the current ‘Plessner renaissance’. Keywords: Helmuth Plessner, Jos de Mul, philosophical anthropology, biology, culture, technology, eccentric positionality, material a priori
