Gregg Lambert examines two facets of the return to religion in the 21st century: the resurgence of overtly religious themes in contemporary philosophy and the global ‘post-secular’ turn that has been taking place since 9/11. He asks how these two ‘returns to religion’ can be taking place simultaneously, and explores the relationship between them. Lambert reflects on statements of these returns from contemporary philosophers including Alain Badiou, John D. Caputo, Jacques Derrida and Jean-Luc Nancy. He discovers a unique – and forboding – sense of the term ‘religion’ that belongs exclusively to our contemporary perspective.
