Abstract

OUR UNDERSTANDING OF OURSELVES and our place in nature constitutes, if not the central, at least a central problem of metaphysics. Yet, faced with this question, modern philosophical thought has for the most part swung helplessly between an empty idealism and an absurd reductivism. It is time we overcame our narrow factionalism and learned not only to think more independently ourselves about persons, minds, and living nature, but to profit from the efforts of those who have already given us concepts and arguments which could help us along this road. Among such writings, Helmuth Plessner's major work, Die Stufen des Organischen und der Mensch, seems to me outstanding, in that it provides both a firm rational basis for the biological sciences, in their many-levelled structure, and for the sciences of man.
