ABSTRACT
One of the aims of Plessner’s The Levels of the Organic and Man [Die Stufen des Organischen und der Mensch, 1928] 1 is to base natural science on a concept of human life. Plessner considers man’s bodily existence as both the foundation and origin of the perspectives of physics and biology, but the human body can only play this role if it is itself understood primarily in a non-scientific way. However, some passages in Plessner’s Levels seem to conflict with this primacy of everyday experience: the human body seems to be defined from a mathematical-physical point of view.
