What Voltaire Actually Said About Wisdom

Voltaire returns to wisdom three times in thinkr's library — more often than to almost anything else. French Enlightenment satirist and crusader for civil liberty. Candide remains a masterwork of philosophical wit.

What follows is every one of those passages, in full, with what each is actually claiming. The language is of its period, but the question underneath is not: what is wisdom for, and what does it ask of you?

Every Voltaire passage on wisdom

“Common sense is not so common.”

“Judge a man by his questions rather than by his answers.”

“Fools admire everything in an author of reputation.”

What holds these together

Read in sequence rather than one at a time, the passages stop being separate aphorisms. Voltaire is not offering three opinions about wisdom; the lines are facets of one position, and the repetition is the argument. The shortest of them — “Common sense is not so common” — is the version you can carry, and the longer ones are what it unpacks into.

Voltaire applied to a real decision

Quotation is the easy part. The harder test is what the position actually does when it meets a situation where every option costs something. thinkr puts two such cases to Voltaire.

Public life feels ugly, exhausting, and still important.

Argued as public courage: You are treating speech as a duty when stakes are real. The danger is becoming addicted to opposition.

The news makes you feel responsible and useless at once.

Argued as stoic discipline: You are matching concern to agency so that concern can become action. The cost is a world that shrinks to the size of your street.

Who disagrees

Plato, Confucius, Immanuel Kant and Aristotle all address wisdom too, and they do not converge. Reading Voltaire alone gives you a coherent position; reading Voltaire against Plato shows you what the position is actually choosing against.
