"I shall suggest, on the contrary, that all communication relies, to a noticeable extent on evoking knowledge that we cannot tell, and that all our knowledge of mental processes, like feelings or conscious intellectual activities, is based on a knowledge which we cannot tell"
About this Quote
The subtext is an argument about authority and what counts as legitimate understanding. By claiming that even our grasp of mental life (feelings, conscious thought) rests on what we “cannot tell,” Polanyi smuggles subjectivity back into the supposedly objective house of science - not as mystical exception, but as the ordinary condition of meaning. He’s also warning against a bureaucratic impulse: if only what can be articulated counts, then the real engines of expertise get erased, along with the people who carry them.
Context matters. Postwar science was ascendant, computing and formal logic were promising to mechanize intelligence, and behaviorism treated inner experience as a black box. Polanyi pushes back with a deceptively plain line that turns the tables: the most rigorous disciplines still depend on the inexpressible. His genius is to make “can’t tell” sound less like failure and more like the quiet infrastructure of every successful explanation.
