有个古人（据说是孔子）说过这样一段话，被外国人翻译过去，广为传颂：
He who knows not and knows not that he knows not, is a fool … shun him. He who knows not and knows that he knows not, is ignorant … teach him. He who knows and knows not that he knows, is asleep … wake him. He who knows and knows that he knows, is a wise man … follow him.
