"Within the broad limits of the physiology of the sense organs, our very perception of the physical world, the colors we discriminate, the smells we become aware of, the noises we hear, are socially patterned and socially circumscribed.  The motivations of men, and even the varying extents to which various types of men are typically aware of them, are to be understood in terms of the vocabularies of motive that prevail in a society and of social changes and confusions among such vocabularies"  (The Sociological Imagination, 1959, p. 162).
