'The satisfactions of manifesting oneself concretely in the world through manual competence have been known to make a man quiet and easy. They seem to relieve him of the felt need to offer chattering interpretations of himself to vindicate his worth. He can simply point: the building stands, the car now runs, the lights are on. Boasting is what a boy does, who has no real effect on the world. But craftmanship must reckon with the infallible judgment of reality, where one's failure or shortcomings cannot be interpreted away.'
Matthew Crawford in Peter Korn, Why We Make Things & Why It Matters, p.56.
