A central function of our evidence is to constrain the epistemic rationality of our propositional attitudes. Our knowledge does this. That fact supports Timothy Williamson's contention that our evidence is identical to our knowledge, ‘E=K’. But it is argued here that some true propositions are evidence without being known. Some of them cannot be known; others are contingently not known. Propositions play the rational role of evidence whenever they are clearly true, whether or not they are known.

没有知识的事实证据

我们证据的一个核心功能是限制我们命题态度的认知合理性。我们的知识就是这样做的。这一事实支持 Timothy Williamson 的论点，即我们的证据与我们的知识相同，“E=K”。但这里争论的是，一些真命题是不为人所知的证据。其中一些是未知的；其他人不知道。只要命题明显正确，无论它们是否为人所知，命题都会发挥证据的理性作用。
