In Idea for a Universal History with a Cosmopolitan Purpose, Kant gives an explanation of his theory of the unsocial sociability of men.
In this, Kant affirms that man has a conflictual nature in his relation to society:
– We carry within us sociability, a penchant for entering society.
“Man has an inclination to associate because in such a state he feels more than a man, that is to say that he feels the development of his natural dispositions”.
– But the man also carries in him an opposite tendency, an inclination to separate,
“He finds at the same time in himself the unsociability which makes him want to settle everything as he pleases and he expects above all to provoke opposition from others
Schopenhauer will take up this thesis in the Hedgehog’s metaphor.
