From Rousseau’s politics and religion to the return to St. Paul in Taubes, Agamben and Badiou, via explorations of politics and original sin in the work of Schmitt and John Gray, Critchley examines whether there can be a faith of the faithless, a belief for unbelievers. Expanding on his debate with Slavoj Žižek, Critchley concludes with a meditation on the question of violence, and the limits of non-violence.
