This volume begins with an essay by Jennifer Kretchmar that provides an overview of conflict theory and consensus theory. According to the author, “even though consensus and conflict theories are often presented as opposing viewpoints, many theorists believe they are complementary.” Katherine Walker offers insight on the Frankfurt School and its contributions to critical theory. She also describes the characteristics of the members of the school and touches on the modern uses of critical theory. Kimberly Cox continues the discussion of sociological theory with an analysis of feminist theory. Throughout the essay, Cox explores feminism’s early themes, its contribution to sociology, and the areas of feminist theory that pose the most resistance. This collection also offers a discussion of postcolonial theory; in her exploration, Samantha Christiansen “traces the historical trajectory of postcolonial theory from prior approaches to social theory and positions postcolonial theory as an outgrowth of Marxism and postmodernism.” P.D. Casteel follows with a description of postmodernism’s general themes, its critique of modernity, and how these critiques have influenced sociological theory. Kretchmar’s “Social Darwinism” attempts to define the recognizable term that often has little to do with the theory of evolution and is instead more focused with Charles Darwin’s ideas and social, scientific, and political methods. Maureen McMahon moves on to Auguste Comte’s social positivism, which relies on empirical data and the belief that only what can be observed can be considered truth.
