"What is tolerance? It is the consequence of humanity. We are all formed of frailty and error; let us pardon reciprocally each other's folly - that is the first law of nature"
About this Quote
The subtext is a quiet demolition of theological and political certainty. Voltaire lived in a France where doctrinal purity could mean censorship, exile, prison, or worse, and where religious conflict still cast a long shadow over public life. His famous outrage at cases like the execution of Jean Calas (a Protestant wrongfully convicted amid Catholic suspicion) hangs behind this sentiment: when institutions claim infallibility, “folly” stops being a private quirk and becomes a pretext for punishment. Tolerance becomes a civic necessity, not a sentimental preference.
Calling reciprocal pardon “the first law of nature” is the slyest move. He hijacks the authority of natural law - usually invoked to justify moral absolutes - and turns it into an argument for humility. It’s an Enlightenment maneuver: ground ethics not in revelation or tradition, but in shared fallibility. Voltaire’s intent isn’t to excuse wrongdoing; it’s to limit cruelty. The baseline demand is modest but radical: before you prosecute, purge, or persecute, remember you’re made of the same errors you’re condemning.
