Life & Wisdom Quote by Voltaire

"When he to whom one speaks does not understand, and he who speaks himself does not understand, that is metaphysics"

About this Quote

Voltaire lands the punchline with the elegance of a salon assassin: metaphysics, he suggests, is the rare conversation where confusion is not a bug but the business model. The line is built like a joke with a blade in it. First, the ordinary premise of speech: one person knows something and transfers it. Then Voltaire flips it twice. The listener doesn’t understand - common enough. But the speaker doesn’t understand either - and still keeps talking. That extra turn is the indictment. Metaphysics becomes a theater of authority, a performance of meaning where tone, reputation, and specialized vocabulary substitute for clarity.

The intent isn’t to deny that big questions exist; it’s to shame a certain kind of intellectual posture. Voltaire, a writer steeped in the Enlightenment’s suspicion of priestly obscurantism, is targeting systems that reward grand, unfalsifiable claims. He had seen how metaphysical language could launder power: if a concept can’t be tested, it can’t be disproven, and if it can’t be disproven, it can be endlessly defended by those with social standing. In that light, the quote reads as an early critique of what we’d now call jargon as gatekeeping.

The subtext is also self-protective. In an era when theology and philosophy were entangled with censorship and persecution, ridiculing metaphysics wasn’t just a stylistic choice; it was a strategic one. Laughter was a way to puncture dogma without writing a treatise that could be prosecuted. Voltaire makes ignorance sound not merely embarrassing, but morally suspect when it’s dressed up as insight.
