"Gaiety is a quality of ordinary men. Genius always presupposes some disorder in the machine"
About this Quote
The second sentence is the real knife. "Genius always presupposes some disorder in the machine" borrows the era’s favorite metaphor - the human as mechanism - then smuggles in sabotage. Genius isn’t presented as divine sparkle but as malfunction: an asymmetry, a noise in the gears, a refusal of smooth operation. It’s also a self-portrait of the intellectual under censorship and patronage. When institutions demand compliance, insight often arrives as irritation, obsession, melancholy, compulsion - states that read like defects until they produce new thought.
The subtext is political as much as psychological: a society that prizes "gaiety" may be optimizing for quiet citizens, not perceptive ones. Diderot makes genius sound expensive, not glamorous. He turns the romantic myth on its head: brilliance isn’t a reward for harmony; it’s what leaks out when the mind can’t quite be domesticated.
