“The aim of human polity is human happiness... There is no obligation on us to be richer, or busier, or more efficient, or more productive, or more progressive, or in any way worldlier or wealthier, if it does not make us happier. Mankind has as much right to scrap its machinery and live on the land, if he really likes it better, as any man has to sell his old bicycle and go for a walk, if he likes that better. It is obvious that the walk will be slower; but he has no duty to be fast.”
