Something Old, Something New: Contemporary Entanglements of Religion and Secularity offers a fresh perspective on debates surrounding a significant if underappreciated relationship between religious and secular interests. In entanglement, secularity competes with religion, but neither side achieves simple dominance by displacing the other. As secular ideas and practices entangle with their religious counterparts, they interact and alter each other in a contentious but oddly intimate relationship.

In each chapter, Wayne Glausser focuses on a topic of contemporary relevance in which something old-e. g., the sacrament of extreme unction, Greek rhetorical tropes, scholastic theology-entangles with something new: psilocybin therapy for the dying, new atheism, cognitive science. As traditional religious knowledge and values come into conflict with their secular counterparts, the old ideas undergo stress and adaptation, but the influence works in both directions. Those with primary allegiance to secular interests find themselves entangled with aspects of religious thinking. Whether they do it intentionally or without knowing, entangled secularists engage with and sometimes borrow from older paradigms they believe they have surpassed. Glausser's approach offers a new perspective in the conversation between believers and secularists. Something Old, Something New is a book that theists, atheists, agnostics, and everyone still searching for the right label will find respectful but provocative.
