What is common in any society is the individual, first element. There are things that are specific to the individual and society own things. The individuals that make up a society are together. To elucidate the problem of the individual and the society have been developed two theories: 1) social nominalism and 2) Social realism. 1) Social nominalism: some argue that the only existing reality is the individual considered in yes same as such.
(2) Social realism: it says that in addition to the individual there is something external to it that is social in origin. What is true for Social nominalism is the individual and group is a name and that outside the individual does not exist any more. This theory since classical antiquity brought an additive theory, it is the sum of the individuals that compose it and outside the individual there is no nothing else. The main representative of this current is late (additive theory). This nominalist position is given in one sentence: nothing exists in the society that does not already exist in the isolated individual; Therefore there is nothing social, everything is individual. In contrast with this current, Durkheim, Social realism which is its holder asserts: there is something external to individuals that comprise society even imposed him to them, that there are social elements that aren’t of the simple sum of the individuals that comprise society, therefore the holders of this theory or current claim that there are social elements external to the conscience of the elements that comprise it. The same sentence they added: unless the society itself.
Within a society should know that it is the individual and that it is the collective. Be part of the same individual lived isolated, from its origins by instinct or need man tended to be grouped. Aristotle said that: the man is a social being par excellence.
