In the wake of the landmark Obergefell v. Hodges Supreme Court decision, the concept of identity has become an all-consuming force in modern culture. But as Carl Trueman masterfully reveals, this fixation on sexual identity is merely a symptom of a far deeper human quest – one that has been unfolding for centuries. From the introspective musings of Augustine to the revolutionary ideas of Marx, Trueman expertly weaves together a rich tapestry of historical perspectives to illuminate the modern understanding of self. By examining the past, clarifying the present, and offering guidance for the future, Trueman provides a profoundly insightful exploration of humanity's eternal search for identity – and the role that Christians must play in shaping its trajectory.
