Our perception of the external world is not a mechanical, straightforward absorption of data. We integrate a vast number of things into a focal awareness, subjecting them to an interpretive framework that is so deeply rooted that we cannot make it explicit.

All understanding, Polyani claimed, is like this. We interiorize a language or a poem “and make ourselves dwell in them. Such extensions of ourselves develop new faculties in us; our whole education operates in this way; as each of ...
