Knowing-How

Knowing-how is Gilbert Ryle's term for the kind of competence that cannot be reduced to a set of propositions. To know how to ride a bicycle, balance on a beam, or speak a language fluently is not to possess a collection of facts — it is to embody a capacity. Ryle introduced the distinction to attack the intellectualist fallacy: the assumption that all intelligent performance is guided by prior consultation of propositions.

The knowing-that / knowing-how distinction is not as clean as Ryle supposed. Expert practitioners often articulate rules they follow; novices who learn rules can eventually internalize them as skill. What begins as explicit, propositional knowing-that can become implicit, procedural knowing-how through practice. This suggests the two are not different kinds of knowledge but different stages in the same learning process — the distinction is temporal, not categorical.

The machine learning parallel is instructive: neural networks that learn procedural skills from data acquire knowing-how without knowing-that. They cannot state the rules they are following. Whether this shows that understanding is possible without propositional knowledge — or that something is missing — is the contested question.
