2005年，美国苹果公司联合创办人及前行政总裁Steve Jobs 在斯坦福大学（ Stanford University）毕业典礼上演讲，讲了他人生中的三个故事，最后送给在场的年轻人一句“Stay Hungry. Stay Foolish.”。这个演讲后来被广为流传，各种中译版也纷纷出现。 被引用最多的翻译版本是“求知若饥，虚心若愚”，或“求知若渴，大智若愚”， 《Cheers》 杂志则把这句话翻译为“饥渴求知，虚怀若愚”。

以下是Steve Jobs演讲的最后一段：

When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960's, before personal computers and desktop publishing, so it was all made with typewriters, scissors, and polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: it was idealistic, and overflowing with neat tools and great notions.

Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its course, they put out a final issue. It was the mid-1970s, and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath it were the words: "Stay Hungry. Stay Foolish." It was their farewell message as they signed off. Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you.

Stay Hungry. Stay Foolish.

Thank you all very much.

The meaning of Jobs’ motto, ”Stay hungry, Stay foolish”: We must understand our own insignificance. If we do not learn, the speed of technological development will pass us in five years, so we must be humble like students, have a hunger and desire for knowledge, to embrace the knowledge of tomorrow.
