We say more than we can know, whether for good or for ill

"just as, owing to the ultimately tacit character of all our knowledge, we remain ever unable to say all that we know, so also, in view of the tacit character of meaning, we can never quite know what is implied in what we say."

Michael Polanyi, Personal knowledge: towards a post-critical philosophy (London: Routledge & Kegan Paul, 1973 (1962, 1958)), 95.
