I offer a model of self‐knowledge that provides a solution to Moore's paradox. First, I distinguish two versions of the paradox and I discuss two approaches to it, neither of which solves both versions of the paradox. Next, I propose a model of self‐knowledge according to which, when I have a certain belief, I form the higher‐order belief that I have it on the basis of the very evidence that grounds my first‐order belief. Then, I argue that the model in (...) question can account for both versions of Moore's paradox. Moore's paradox, I conclude, tells us something about our conceptions of rationality and self‐knowledge. For it teaches us that we take it to be constitutive of being rational that one can have privileged access to one's own mind and it reveals that having privileged access to one's own mind is a matter of forming first‐order beliefs and corresponding second‐order beliefs on the same basis.

In his , Williams offered a solution to Moore's paradox that centred on the concept of justification. Consider the omissive Moore-paradoxical sentence: p and I do not believe that p.Williams appealed to the principle Whatever justifies me in believing that p justifies me in believing that I believe that p.Suppose that I am justified in believing . Then I am justified in believing its first conjunct. By I am justified in believing that I believe that p. Since I am also (...) justified in believing the second conjunct, I am justified in believing that I do not believe that p. Williams claimed that ‘this is impossible, because anything that justifies me in believing that something is the case renders me unjustified in believing that it is not the case’ . 1In a response to Williams, I argued that is false. Williams concedes this objection, and in Williams he seeks to offer a variant on his justificationist solution to Moore's paradox that does not rest upon . Consider this instance of . There will be a third world war, and I do not believe that there will be a third world war.Suppose that I am justified in believing the first conjunct on …. (shrink)
