Sorensen here offers a unified solution to a large family of philosophical puzzles and paradoxes through a study of "blindspots": consistent propositions that cannot be rationally accepted by certain individuals even though they might by true.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

On the basis of arguments showing that none of the most influential analyses of Moore’s paradox yields a successful resolution of the problem, a new analysis of it is offered. It is argued that, in attempting to render verdicts of either inconsistency or self-contradiction or self-refutation, those analyses have all failed to satisfactorily explain why a Moore-paradoxical proposition is such that it cannot be rationally believed. According to the proposed solution put forward here, a Moore-paradoxical proposition is one for which (...) the believer can have no non-overridden evidence. The arguments for this claim make use of some of Peter Klein’s views on epistemic defeasibility. It is further suggested that this proposal may have important meta-epistemological implications.

Propositions such as are paradoxical, in that even though they can be true, they cannot be truly asserted or believed. This is Moore’s paradox. Sydney Shoemaker has recently ar- gued that the paradox arises from a constitutive relation that holds between first- and second-order beliefs. This paper explores this approach to the paradox. Although Shoemaker’s own account of the paradox is rejected, a different account along similar lines is endorsed. At the core of the endorsed account is the claim that (...) conscious beliefs are always partly about themselves; it will be shown to follow from this that conscious beliefs in Moorean propositions are self-contradictory.

(A) I went to the pictures last Tuesday but I don’t believe that I did (1942, p. 543) or (B) I believe that he has gone out. But he has not (1944, p. 204) would be “absurd” (1942, p. 543; 1944, p. 204). Wittgenstein’s letters to Moore show that he was intensely interested in this discovery of a class of possibly true yet absurd assertions. Wittgenstein thought that the absurdity is important because it is “something similar to a contradiction, thought (...) it isn’t one” (1974, p. 177). What is the explanation of the absurdity of saying or believing something about myself that might be true? Wittgenstein thought that although the explanation will say “something about the logic of assertion” it will also show that “logic isn’t as simple as logicians think it is”. So although the explanation should.. (shrink)

I argue that Moore's propositions, for example, 'I went to the pictures last Tuesday but I don't believe that I did' cannot be rationally believed. Their assertors either cannot be rationally believed or cannot be believed to be rational. This analysis is extended to Moorean propositions such as God knows that I am an atheist and I believe that this proposition is false. I then defend the following definition of assertion: anyone asserts that p iff that person expresses a belief (...) that p with the intention of causing relevant epistemic change in the cognition of an actual or potential audience.

As G. E. Moore famously observed, sentences such as 'It's raining but I don't think it is', though they aren't contradictory, cannot be used to make coherent assertions.' The trouble with such sentences is not a matter of their truth conditions; such sentences can readily be true. Indeed, it happens often enough with each of us that we think, for example, that it isn't raining even though it is. This shows that such sentences are not literally contradictory. But even though (...) such sentences have unproblematic truth conditions, we cannot say the same about their conditions of assertibility. There are no circumstances in which one can use such sentences to perform coherent assertoric speech acts. Situations exist in which these sentences would be true, but none in which anybody could use them to say so. (shrink)

Moore’s paradox occurs with sentences, such as (1) It’s raining and I don’t think it’s raining. which are self-defeating in a way that prevents one from making an asser- tion with them.1 But Mark Crimmins has given us a case of a sentence that is syntactically just like (1) but is nonetheless assertible. Suppose I know somebody, and know or have excellent reason to believe that I know that very person under some other guise. I do not know what that (...) other guise is, though I do know that I believe that the person I know under that other guise is an idiot. (shrink)

Positive thinkers love Watty Piper's The little engine that could. The story features a train laden with toys for deserving children on the other side of the mountain. After the locomotive breaks down, a sequence of snooty locomotives come up the track. Each engine refuses to pull the train up the mountain. They are followed by a weary old locomotive that declines, saying "I cannot. I cannot. I cannot." But then a bright blue engine comes up the track. He manages (...) to chug over the mountain by averring "I think I can. I think I can. I think can.". (shrink)
