When we take a walk, read a book, make a dress, hire a servant, visit a friend, attend a concert, choose a wife, cast a vote, enter into business, we always do it in the hope of attaining something good. The clue of goodness is accordingly a veritable guide of life. On it depend actions far more minute than those just mentioned. We never raise a hand, for example, unless with a view to improve in some respect our condition. Motionless we should remain forever, did we not believe that by placing the hand elsewhere we might obtain something which we do not now possess.
