CONCEPT
Thinking Tools
Dennett's term for the external cognitive instruments — language, notation, institutions, and now AI — that humans download into biological hardware never designed for the feats it performs.
Thinking tools is Dennett's name for the cultural instruments that extend biological cognition beyond what unaided brains could achieve. His central claim, developed most fully in Intuition Pumps and Other Tools for Thinking (2013), is that human intelligence is not the expression of a powerful biological substrate but the cumulative effect of tools — alphabets, arithmetic, logic, diagrams, metaphors, labels, institutions — that we inherit from prior generations and install into brains that evolved for none of them. The framework reframes the AI moment: large language models are not competitors to human intelligence but the latest and most powerful additions to the toolkit that made human intelligence what it is.

The thesis inherits from Vygotsky, from Douglas Hofstadter (Dennett's longtime collaborator), and most directly from Andy Clark's extended mind. What Dennett added was the catalogue and the rhetorical force: specific tools — rapoport rules, surely operators, jootsing, deepities — presented as portable cognitive instruments
