With a historical thread woven throughout the chapters, the book presents a diverse selection of major classical theorists including Marx, Spencer, Durkheim, Weber, Mead, Simmel, Martineau, Gilman, Douglass, Du Bois, Parsons, and the Frankfurt School.  Authors Kenneth Allan and Sarah Daynes focus on the specific views of each theorist, rather than schools of thought, and highlight modernity and postmodernity to help readers understand how classical sociological theory applies to their lives.
