According to Simmel (1910), human being has a prior knowledge so the nature is possible due to human generality and thinking. So the empirical society also possible due to the analogues with nature and it is also the aphoristic condition. But in Kantian theory it cannot be characterized by simple phrase. Here also exist the same rules as nature, that a society only through the process of human consciousness. The consciousness processes wherewith socialization. It is possible due to reciprocal determination of individual, the reciprocal significance of the individual for the totality of the other individuals. so it become a kind of principle which is not recognized in the abstract, but its lie on society and expresses itself in the real practice. This kind of structure depends up on generality, a certain degree of individuality and its function. The causal interdependence in a social things, behavior and practice determined social element being and doing of every other. Thus it brings into existence other external network of society and transformed into a teleological interdependence. Every human has personal attitude, egos, individual bearers because all human beings are creature of nature and they all grown in a soil of personality which is self- exist and self-determining. All this above subjectivity determined the life- process at which point the peculiarity of the same becomes a necessary member in the life of the universe. So the fundamental category gives to the consciousness of the individuality and it distinguishes the individual as become a social element and society is possible.
