People here argue about religion interminably, but it appears that they are competing at the same time to see who can be the least devout. Lettres Persanes (1721)

I acknowledge that history is full of religious wars: but we must distinguish; it is not the multiplicity of religions which has produced wars; it is the intolerant spirit animating that which believed itself in the ascendant. Lettres Persanes (1721)
