Though the Enlightenment is sometimes represented as the enemy of religion, it is more accurate to see it as critically directed against various (arguably contingent) features of religion, such as superstition, enthusiasm, fanaticism and supernaturalism. Indeed the effort to discern and advocate for a religion purified of such features – a “rational” or “natural” religion – is more typical of the Enlightenment than opposition to religion as such. Even Voltaire, who is perhaps the most persistent, powerful, vocal Enlightenment critic of religion, directs his polemic mostly against the Catholic Church in France – “l'infâme” in his famous sign-off in his letters, “Écrasez l'infâme” (“Crush the infamous”) refers to the Church, not to religion as such. However, controversy regarding the truth-value or reasonableness of religious belief in general, Christian belief in particular, and controversy regarding the proper place of religion in society, occupies a particularly central place in the Enlightenment. It's as if the terrible, violent confessional strife in the early modern period in Europe, the bloody drawn-out wars between the Christian sects, was removed to the intellectual arena in the Enlightenment and became a set of more general philosophical controversies.
