About Voltaire

Voltaire (François-Marie Arouet, 1694–1778) was the French Enlightenment’s sharpest satirist and campaigner for toleration, author of Candide and countless polemics. Imprisoned in the Bastille, exiled in England, resident at Cirey and Ferney, he fought judicial fanaticism in cases such as Calas.

Interpretation

Voltaire's line is usually read as cynicism, which inverts it. In the poem he is arguing that belief in a just God is socially necessary, because without it there is no reason for the powerful to restrain themselves. The claim is about what a society needs rather than about whether God exists — he is arguing against atheism among those who, as he puts it, would be dangerous without it. The sentence is a political argument in the form of a paradox.

Why it matters

Read accurately it is a claim about social order, not about theology, and it concedes more to the need for belief than most of his reputation suggests.
