To look at a thing is very different from seeing a thing. One does not see anything until one sees its beauty. Then and then only, does it come into existence.

Everyone is looking for themselves, even if they don't know what they're looking for.

下一次绿色革命不会仅仅来自实验室，它将来自世界各地的农田。

实现明天理想的唯一障碍是今天的疑虑。

发现的喜悦无疑是人类心灵所能感受到的最活跃的。
