把这一句，留给此刻的你
I hold that the propositions embodied in natural science are not derived by any definite rule from the data of experience, and that they can neither be verified nor falsified by experience according to any definite rule.
我认为，自然科学中所包含的命题，并不是由经验的数据所确定的规则所推导出来的，它们既不能被经验根据任何确定的规则所证实，也不能被经验所证伪。
