成为勇者的简单步骤，是不参与谎言。一个真理的词语重如泰山。如果对邪恶保持沉默，把它埋在我们内心深处，以至于表面上看不出它的迹象，那我们就是在植入它，它将在未来以千倍的速度崛起。
The simple step of a courageous individual is not to take part in the lie. One word of truth outweighs the world. In keeping silent about evil, in burying it so deep within us that no sign of it appears on the surface, we are implanting it, and it will rise up a thousand fold in the future.
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.
