Abstract

Man’s essence is not to be found in his belonging to a species, i.e. in his possessing of an essence. And our humanity is not to be defined according to our being “rational”: theoretical reason stands in a metaphysical continuity with sensation and perception, realities of the natural world. Man is, however, not a given, natural thing but a being existing in history. Our history’s principle and energy is freedom. Each of us receives a call to become and to act and the free answer she or he gives to this call can not come from anybody else. It alone allows us to understand the question: who is man?
