There is no man, however wise, who has not at some period of his youth said things, or lived in a way the consciousness of which is so unpleasant to him in later life that he would gladly, if he could, expunge it from his memory.
无论多么聪明的人，在他年轻时都曾说过或做过一些事情，后来回想起来会感到不快，以至于如果可能的话，他会很高兴地从记忆中抹去。
自私性是一种自爱，怜悯心是一种他爱。一个人想要得到他人的爱，他自己首先应具备爱人之心。
