"Invention consists in avoiding the constructing of useless contraptions and in constructing the useful combinations which are in infinite minority"
About this Quote
Poincare skewers the romantic myth of invention as a fireworks show of novelty. For a mathematician who lived through the second industrial revolution, when gadgets and mechanisms multiplied faster than wisdom about what to do with them, “infinite minority” is the quiet punchline: the space of possibilities is effectively endless, but the subset worth building is vanishingly small. The line reads like a technical definition delivered with a philosopher’s impatience for clutter.
The intent is corrective. Poincare reframes creativity as disciplined selection, not unbounded production. “Avoiding” comes first for a reason. In his world, the hard part isn’t generating options; it’s resisting the seduction of elegant-but-pointless constructions, the mental equivalent of a Rube Goldberg machine. That word “contraptions” carries a faint sneer, a reminder that complexity can be a kind of vanity project.
The subtext is also epistemic: usefulness isn’t inherent in a thing; it emerges from fit. “Useful combinations” hints at invention as recombination under constraints - taking known elements (concepts, parts, methods) and arranging them so they suddenly answer a real problem. This is Poincare the mathematician talking about proofs as much as engines: most combinations of ideas are noise, a few are signal.
Context matters: Poincare wrote in an era newly intoxicated with progress and machinery, yet he insists that progress is not the pileup of artifacts. It’s the rare judgment call that separates the clever from the consequential.
