我们期望晚餐不是出自屠夫、啤酒商或面包师的仁慈，而是出自他们对自身利益的考虑。
Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.
出自先秦《荀子·礼论》。生是人的开始，死是人的终结。开始与终结都做得好，那么他的为人之道就完善了。说明意在劝人行仁行善，要善始善终。
The world is full of people who have never, since childhood, met an open doorway with an open heart.
