The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.
译文：为人处世必须以忠厚老实的人为效仿对象，传承家业必须要把勤俭节约的习惯传给子孙后代。赏析：忠厚老实之人做事有自己的原则，他们不会耍心机，不会算计别人，这样的人值得我们尊重。不管是富贵或是贫穷，我们都应把勤俭节约的习惯放在心头。贫穷时不节俭，会更加贫穷，富贵时不节俭，万贯家财都会被败光。
译文：学习不以广博为贵，贵在学得正确，说话不以漂亮动听为贵，贵在表达得当。赏析：读书求学要走正道，要有正确的学习观，不能学习旁门左道。和别人交往，说话不一定要动听，一定要正确表达，不要出口伤人。
