Read the full account

From the early 1760s, especially around Calas, Voltaire closed letters with écrasez l’infâme, a slogan against ecclesiastical power that polarised French public language.

Context

Voltaire is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Why it matters

A slogan is not a statute. It is still a polarisation path.

A slogan is not a statute. It is still a polarisation path.
