Book excerpt: Modern culture is obsessed with identity. Since the landmark Obergefell v. Hodges Supreme Court decision in 2015, sexual identity has dominated both public discourse and cultural trends—and yet, no historical phenomenon is its own cause. From Augustine to Marx, various views and perspectives have contributed to the modern understanding of self. In The Rise and Triumph of the Modern Self, Carl Trueman carefully analyzes the roots and development of the sexual revolution as a symptom, rather than the cause, of the human search for identity. This timely exploration of the history of thought behind the sexual revolution teaches readers about the past, brings clarity to the present, and gives guidance for the future as Christians navigate the culture's ever-changing search for identity.
