From the Introduction:
This essay deals with the writings of social scientists on the nature of Puerto Rican culture, and seeks to clarify some of the concepts they use. I have drawn mainly from scholars in sociology and anthropology; where relevant, the views of observers in related fields are included.
The essay’s concern is with culture – its definition, its relevance, and its particular meaning in the Puerto Rican case. To a major extent, political implications are not spelled out. The hope is, however, that the political dialogue may be clarified by achieving some common agreement on terms.
