Methodic Doubt

Methodic doubt is the [[ReneDescartes|Descartes]] procedure foregrounded in 174.读笛卡尔，是件大事: doubt what can be doubted, not to remain in skepticism forever, but to clear inherited prejudice and find a starting point that survives doubt. The episode compares this to clearing a building site before construction.

The source distinguishes this method from ordinary cynicism. Senses, dreams, mathematical assumptions, and the external world may all be put in question, but the purpose is to reach [[CogitoErgoSum|我思故我在]] and then build through Rationalist Method.

Key Claims

• Doubt is a method, not the endpoint.
• The target is inherited certainty, lazy authority, and untested belief.
• The episode values doubt because it can make a person responsible for what they believe.
• The method becomes useful in ordinary life only when bounded; everyday action cannot wait for absolute proof of everything.
• In the AI-era extension, doubt helps preserve Human Judgment Under AI by preventing fluent technical output from becoming automatic authority.

Connections

• Rene Descartes / 笛卡尔 - thinker associated with the method.
• Discourse on Method / 《谈谈方法》 - main text through which the episode introduces the method.
• Cogito Ergo Sum / 我思故我在 - first secure point reached through doubt.
• Rationalist Method - constructive method after doubt clears the ground.
• Rational Humility - adjacent discipline for keeping claims accountable after the initial certainty point.
• Computing Versus Thinking and Human Judgment Under AI - AI-era extension in the source.
