懂得如何揣测他人。智者要小心防范恶人的陷阱。要测试他人的判断力，你须有高超的判断力。了解他人的特性，比了解植物和矿石的特性更重要。这真是人生中最精明的技艺之一。辨别金属，你可听其音；辨别人，你可闻其言。一个人的言语可证明其是否正直，行动则更具说服力。揣度别人需要特别的小心，深入的观察，敏锐的辨别与明智的判断。
know how to test people. the care of the wise must guard against the snare of the wicked. great judgment is needed to test that of another. it is more important to know the characteristics and properties of persons than those of vegetables and minerals. it is indeed one of the shrewdest things in life. you can tell metals by their ring and men by their voice. words are proof of integrity, deeds still more. here one requires extraordinary care, deep observation, subtle discernment, and judicious decision.
