That the happiness of man may still remain imperfect, as wants in this place are easily supplied, new wants likewise are easily created; every man, in surveying the shops of London, sees numberless instruments and conveniencies, of which, while he did not know them, he never felt the need; and yet, when use has made them familiar, wonders how life could be supported without them. Thus it comes to pass, that our desires always increase with our possessions; the knowledge that something remains yet unenjoyed, impairs our enjoyment of the good before us.
