But, despite the vast incompleteness of our knowledge, recent research suggests that most people think that they know far more than they actually do. We freely admit to not knowing everything about how a helicopter flies or a printing press prints, but we are not nearly modest enough about our ignorance.
但是，尽管我们的知识犹如沧海一粟，最近的研究表明，大多数人认为他们所知道的事情要远远超过实际知道的事情。我们爽快地承认，我们对于直升飞机如何飞翔或者印刷机如何印刷一窍不通，但是对于我们的无知却并不足够谦虚。
