“Doubts in the matter of religion, far from being acts of impiety, ought to be seen as good works, when they belong to a man who humbly recognizes his ignorance and is motivated by the fear of displeasing God by the abuse of reason.”
– Denis Diderot, Addition aux Pensées philosophiques, par. 1, in Diderot, Oeuvres Complète (1875), 1:158 (quoted by Philip Clayton).
