Abstract
The most original aspect of Hedwig Conrad-Martius’ research is her interpretation of nature, performed through the phenomenological method. She pinpoints the very essences of the natural phenomena, discovering entelechies inside them and a trans-physical dimension. She reads the evolution of nature in a new way, against the deterministic interpretation of it. Inside nature one can discover many levels, qualitatively different. The human being participates to all of them, but his/her peculiarity is linked to the mental–spiritual life.
