It consists of a series of specially commissioned chapters around binary or dichotomous themes. Although many sociologists are critical of dichotomous models of sociological theory and research, the device crops up again and again in the history and practice of the subject. Jenks and his colleagues use the dichotomies to situate students in current sociological arguments and topical debates. For example, by examining contradictory pairs of concepts like structure/agency, local/global, continuity/change, students are introduced to alternative explanations for aspects of human conduct over a whole series of issues.
