Abstract: In our traditional conception,there is a dialectical contradiction between individual and society.Nevertheless,according to Karl Marx,society as a concept of relationship constitutes social space of individual activities,and socialization constitutes social development and social realization of humanities and expanding of social space of individual activities,and relevantly,development of both humanities and socialization level of individuals constitutes the core content of social development. Therefore,Karl Marx's concept of society and socialization is of high value in social critics and social guiding.What's more,socialization in Karl Marx's theoretical research constitutes his answer to the relationship between particularity and generality.
