Book excerpt: The Development of Sociological Theory: Readings from the Enlightenment to the Present brings together excerpts from 96 original works by important theorists from the roots of sociological thought through the contemporary and post-modern periods. Noted theory scholar A. Javier Treviño has created an anthology with breadth and variety, while staying mainly within theoretical schools and traditions that are sociological. The selections have been selected and edited for classroom use and are presented according to two orderings—as a rough chronology that illustrates the historical development of theoretical knowledge in sociology and as a typology of systems of sociological theorizing for more methodical consideration.
