In mathematics, the art of proposing a question must be held of higher value than solving it.

"The writer is a man who is always trying to find the right balance between form and content, between style and substance, between art and life."

【译文】 孔子说：“有一种人，不了解情况就冒然行事，我不会这样。多听，向先进人物学习；多看，把细节牢记在心。就是掌握知识的最好方法。”
