"Sociologists such as George Herbert Mead and Charles Horton Cooley thought of society as a human laboratory where they could observe and understand human behavior to be better able to address human needs, and they used the city in which they lived as a living laboratory."

“Our life is all one human whole, and if we are to have any real knowledge of it we must see it as such. If we cut it up it dies in the process: and so I conceive that the various branches of research that deal with this whole are properly distinguished by change in the point of sight rather than by any division in the thing that is seen. Accordingly, in a former book , I tried to see society as it exists in the social nature of man and to display that in its main outlines. In this one the eye is focussed on the enlargement and diversification of intercourse which I have called Social Organization, the individual, though visible, remaining slightly in the background.”

“BY primary groups I mean those characterized by intimate face-to-face association and cooperation. 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. Perhaps the simplest way of describing this wholeness is by saying that it is a "we"; it involves the sort of sympathy and mutual identification for which "we" is the natural expression. One lives in the feeling of the whole and finds the chief aims of his will in that feeling.”

“To get away from one's working environment is, in a sense, to get away from one's self; and this is often the chief advantage of travel and change.”

“A separate individual is an abstraction unknown to experience, and so likewise is society when regarded as something apart from individuals.”

“Strong joy and grief depend upon the treatment this rudimentary social self receives.”

“The group self or "we" is simply an "I" which includes other persons. One identifies himself with a group and speaks of the common will, opinion, service, or the like in terms of "we" and "us." The sense of it is stimulated by co-operation within and opposition without.”
