Context

“So inveterate is their appetite for Heaven that our best method, at this stage, of attaching them to earth is to make them believe that earth can be turned into Heaven at some future date by politics or eugenics or "science" or psychology, or what not. Real worldliness is a work of time—assisted, of course, by pride, for we teach them to describe the creeping death as good sense or Maturity or Experience. Experience, in the peculiar sense we teach them to give it, is, by the bye, a most useful word. A great human philosopher nearly let our secret out when he said that where Virtue is concerned "Experience is the mother of illusion"; but thanks to a change in Fashion, and also, of course, to the Historical Point of View, we have largely rendered his book innocuous.
