One of the insights of C.S. Lewis’ The Abolition of Man is that we are moved not by abstract formulas, by bare concepts, or even by the “facts, facts, facts” that the schoolmaster Gradgrind sought to stuff into his young receptacles, but by visions of beauty and worth. These visions stir what Lewis calls the “chest,” the seat of powerful and almost rational feeling; not the appetite, which is located in the belly, or ratiocination, located in the head.
