In a thoroughly updated second edition of his popular and engaging book, John D. Caputo revisits Augustine's ancient question "what do I love when I love my God?" and presses it into service in the post-modern world. Accessible but without compromising the big ideas, he raises the question of what religion means today in the face of widespread religious violence after 9/11, of spreading secularization, the dazzling discoveries of contemporary cosmology, and the eerie advent of the "post-human" world. All along sculpting the idea of a post-modern, post-secular "religion without religion," which turns on the "mystical element" of our lives, he wonders what the future of traditional religion will be, or whether it even has one.On Religion will fascinate anyone interested in the challenges religion faces in the contemporary world. It offers an ideal starting point from which undergraduate and postgraduate students, teachers, and lecturers can explore religion and philosophy today.
