I suspect this quote from William James is at least as true today as when he wrote it. It may also be a far more pernicious problem than we are usually prepared to admit, because I think James, whether he knew it or not was foretelling the death of academia.
Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!
