把这一句，留给此刻的你

It is that of increasing knowledge of empirical fact, intimately combined with changing interpretations of this body of fact - hence changing general statements about it - and, not least, a changing a structure of the theoretical system.

它是增加对经验事实的知识，并与对这一事实体的不断变化的解释密切结合在一起，从而改变对这一事实体的一般说法，尤其是改变理论体系的结构。

— Talcott Parsons 帕森斯
