kk states that knowing entails knowing that one knows, and K¬K states that not knowing entails knowing that one does not know. In light of the arguments against kk and K¬K, one might consider modally qualified variants of those principles. According to weak kk, knowing entails the possibility of knowing that one knows. And according to weak K¬K, not knowing entails the possibility of knowing that one does not know. This paper shows that weak kk and weak K¬K are much stronger than they initially appear. Jointly, they entail kk and K¬K. And they are susceptible to variants of the standard arguments against kk and K¬K. This has interesting implications for the debate on positive introspection and for deeper issues concerning the structure and limits of knowability.

KK，知识，可知性

kk 说知道意味着知道一个人知道，而 K¬K 说不知道意味着知道一个人不知道。鉴于反对 kk 和 K¬K 的论点，人们可能会考虑这些原则的模态限定变体。根据 weak kk 的说法，知道意味着知道一个人知道的可能性。根据 weak K¬K 的说法，不知道意味着知道一个人不知道的可能性。这篇论文表明弱 kk 和弱 K¬K 比它们最初出现的要强得多。它们共同蕴含 kk 和 K¬K。并且它们容易受到反对 kk 和 K¬K 的标准论证变体的影响。这对于关于积极内省的辩论以及关于可知性的结构和限制的更深层次问题具有有趣的意义。
