把这一句，留给此刻的你

So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

就假设而言，谁也不要指望从天文学中得到任何不能提供它的确定的东西，以免他把为另一个目的而设想的真理观念当作真理来接受，离开这项研究时，他会比刚开始时更愚蠢。

— Nicolaus Copernicus 哥白尼
