The judgements of young boys, as Emerson noted, are swift, confident, and summary. Eventually, they become more equivocal, less certain. Their eyes flicker. They begin to speak from the calculator in the head.
Wisdom is a descent from the head’s either/or to the heart’s both/and. “If thine eye be single, thy whole body will be full of light.”
There are habits of the head, the heart and the body. Of these three centres of intelligence, the body is the most difficult to de-condition. It’s where memories congeal. And where pain is.
Knowledge is the head. An accumulation of past.
Knowing is the heart. An experience of now.
Knowing has no antecedents and no thought process.
Socrates: “All I know is that I know nothing.”
