"Each problem that I solved became a rule, which served afterwards to solve other problems"
About this Quote
The subtext is ambitious and slightly combative. Descartes is arguing that knowledge should be engineered: break a messy question into parts, verify each step, and keep what works as a general tool. That’s not just mathematical efficiency; it’s a philosophy of intellectual self-reliance. In a Europe still structured by scholastic tradition and deference to Aristotle, Descartes’ method implies that the mind can rebuild certainty from the ground up, no priestly gatekeepers required.
Context matters: this is the era of analytic geometry, of algebra learning to speak the language of space. Descartes’ own breakthroughs literally turned specific geometric problems into general symbolic rules, and then used those rules to colonize new terrain. The sentence also captures a modern anxiety: without rules, you’re improvising forever. With rules, you risk turning thinking into bureaucracy. Descartes is betting that disciplined procedure doesn’t shrink imagination - it scales it.
