[M]an has been accustomed, ever since he was a boy, to having a dozen incompatible philosophies dancing about together inside his head. He doesn't think of doctrines as primarily "true" or "false," but as "academic" or "practical," "outworn" or "contemporary," "conventional" or "ruthless." Jargon, not argument, is your best ally in keeping him from the Church. Don't waste time trying to make him think that materialism is true! Make him think it is strong or stark or courageousโthat it is the philosophy of the future. That's the sort of thing he cares about.
C. S. LewisNever forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on the Enemyโs (Godโs) groundโฆHe [God] made the pleasure: all our research so far has not enabled us to produce one. All we can do is to encourage the humans to take the pleasures which our Enemy [God] has produced, at at times, or in ways, or in degrees, which He [God] has forbidden.
