This fully updated edition of Kenneth Allan's acclaimed social theory text emphasizes the diversity of classical and contemporary theory, critical thinking, and the importance of historical context. Chosen for the diversity of their perspectives and their suitability for introducing students to contemporary social thought, a wide variety of theorists appear in the text with their individual voices vividly intact. The author engages students in the historic and contemporary changes that have spawned diverse social theories and invites them to see theory as an element within a broader range of critical thinking skills that can be applied to current social problems.
