“How different everything is for the craftsman who transforms a part of the world with his own hands, who can see his work as emanating from his being and can step back at the end of the day or lifetime and point to an object- whether a square of canvas, a chair or a clay jug- and see it as a stable repository of his skills and an accurate record of his years, and hence feel collected together in one place, rather than strung out across projects which long ago evaporated into nothing one could hold or see.”
