"Divide each difficulty into as many parts as is feasible and necessary to resolve it"
About this Quote
The specific intent is almost procedural: don’t wrestle the monster whole. Reduce it to smaller questions you can actually test, compute, or reason through. The subtext is bolder: the mind, properly disciplined, is capable of making the world legible. That’s the quiet revolutionary claim. Breaking a problem down is not just efficient; it’s an assertion of intellectual sovereignty. You don’t ask the old authorities for permission to understand. You create a sequence of manageable steps and let clarity accumulate.
The line also telegraphs the emerging mathematical sensibility of the era. Descartes, the architect of analytic geometry, is importing a mathematician’s confidence into philosophy: complex truths can be reached by decomposition and orderly reconstruction. “Feasible and necessary” matters, too. It’s a warning against both paralysis by analysis and macho simplification. Cut enough to make progress, not so much that you lose the shape of what you’re solving.
