Descartes, Start to Finish
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
One philosopher's single project, reassembled across three units: demolish everything doubtful, find bedrock, rebuild—and meet a princess at the weak joint.
The demolition. Descartes' method of doubt treats anything doubtable as false—not from despair but engineering: a foundation is tested by loading it. The dream argument condemns the senses wholesale: dreaming and waking can be indistinguishable from inside, so experience cannot certify which one is running now. The evil demon finishes the job, a deceiver strong enough to corrupt even arithmetic. By design, nothing survives—almost.
Do not grade the project by its failures alone—fields are founded by ambitious arguments that half-succeed. Both halves are the inheritance, and every unit after this one spent it.
