有人问斯多葛学派的创始人芝诺:“谁是你的朋友?”他回答:“另一个自我。”人生在世,不能没有朋友。在所有朋友中,不能缺了最重要的一个,那就是自己。缺了这个朋友,一个人即使朋友遍天下,也只是表面的热闹而已,实际上他是很空虚的。一个人是不是自己的朋友,有一个可靠的测试标准,就是看他能否独处,独 Someone asked the founder of the Stoic school, Zeno: “Who is your friend?” He replied: “Another self.” Life is alive and one cannot be without friends. Among all the friends, one cannot miss the most important one, that is, oneself. Lack of this friend, even if a friend is all over the world, it is only a lively appearance. In fact, he is very empty. A person is not his own friend. He has a reliable test standard. It is to see if he can be alone and alone.
