What is capture system?

Capture system is a concept in personal epistemology: New captures go to a hot inbox — only processed items move to permanent storage. The separation protects both speed of capture and integrity of storage.

Example: You hear a compelling idea during a podcast while driving. You voice-capture a rough note: 'autonomy requires infrastructure — like free speech requires courts.' That note lands in your daily inbox. That evening, during processing, you rewrite it as a permanent note: 'Autonomy is not the absence of structure but the presence of self-chosen structure. Freedom requires infrastructure to be exercised — courts for speech, budgets for financial freedom, capture systems for cognitive freedom.' The fleeting capture took four seconds. The permanent note took four minutes. If you had tried to write the permanent version while driving, you would have captured nothing.

This concept is part of Phase 3 (Capture Systems) in the How to Think curriculum, which builds the epistemic infrastructure for capture systems.
