Recent debates in Europe and the U.S. about key societal issues like abortion or same-sex marriages show that, in contemporary Western societies, there is no longer a natural law common to believers and non-believers. In other words, and whatever the intellectual genealogy of contemporary secularism may be, the gap between religious and secular values has become such that there is no longer a “common Go(o)d”. In this context, many share a concern on how to maintain cohesion within increasingly diverse societies. Far from being a theoretical issue, this question is becoming more urgent because of the growing presence of Muslims in Europe. But in essence, the debate is not limited to Islam; it deals with the meaning of religion (any religion) in a secular Europe.
