Social theory can usefully be conceived in terms of four key paradigms: functionalist, interpretive, radical humanist, and radical structuralist. The four paradigms are founded upon different assumptions about the nature of social science and the nature of society. Each generates theories, concepts, and analytical tools which are different from those of other paradigms and together they provide a more balanced understanding of the phenomenon under consideration. This book demonstrates that an understanding of these different paradigms and how they can be applied leads to a better understanding of the multi-faceted nature of political economy.
