CORE DEFINITION

The mind is not confined within the skull but can extend into the external environment. Your notebook, phone, and even your search habits are physical components of your cognitive processes. If they are removed, your cognitive abilities would be impaired, just like a lobectomy. Scaffolding role: Tools are organs. Do not regard tools (AI, note-taking software) merely as external objects. When designing workflows, treat them as 'prostheses' and 'external hard drives' for your brain, integrating them deeply. Optimizing your toolchain is physically upgrading your intelligence.

The extended mind thesis holds that the mind is not limited to the skull; external objects (notebooks, phones) that stably perform cognitive functions are part of mental processes. It challenges the dichotomy of 'mind inside, world outside'.
