Abstract

The surplus of impulses is a key category in Gehlen’s anthropobiology to understand the process of hominisation and humanisation. From the dedifferentiation of human instincts and the primitivisation of man’s anatomy, to the role of experience, institutions, and speech, the surplus of impulses is a source that flows between the inner and the outer, by feeding the action circle that whether translates in activity or is redirected inwards in order to become a movement of volitional constitution. The ambivalence in which Gehlen deals with this function of freedom gives rise to a pessimistic and sacrificial idea of man. However, he posits certain basic elements of a hedonistic theory of speech from which we can better understand the stabilizing task of language as cornerstone of institutions.
