Ernest W. Burgess, The city (1925)
“ By primary groups I mean those characterized by intimate face-to-face association and co-operation. They are primary in several senses, but chiefly in that they are fundamental in forming the social nature and ideals of the individual. The result of intimate association, psychologically, is a certain fusion of individualities in a common whole, so that one’s very self, for many purposes at least, is the common life and purpose of the group. ”
