Personal Knowledge (Polanyi)
Knowledge is irreducibly personal—requiring the knower's commitment, judgment, and tacit engagement—against the positivist fiction of detached objectivity.
Personal knowledge is Polanyi's alternative to the positivist ideal of objective, impersonal, fully articulable scientific knowledge. All knowing, Polanyi argued, involves the knower's personal commitment—her judgment about what counts as relevant, her evaluation of what constitutes evidence, her sense of what matters. The scientist who publishes a finding stakes her reputation on its truth. This commitment is not a regrettable human limitation but what makes the knowledge meaningful. It transforms mere information into understanding. The lie of objectivity—that genuine knowledge is detached, impersonal, and expressible in propositions that can be verified independently of any knower—obscures the tacit dimension on which all explicit knowledge depends: someone must know what the symbols mean, must judge what the evidence indicates, must evaluate what the results signify. AI outputs possess the surface markers of impersonal knowledge—authoritative, balanced, comprehensive—while lacking the personal commitment that gives knowledge its epistemic weight.
