Moore's paradox is a paradox in which certain kinds of belief or assertion, such as a belief that ?it is raining and I do not believe that it is raining?, are irrational despite involving no obvious contradiction in what is believed. But is there a parallel paradox involving other kinds of attitude, in particular desire? I argue that certain kinds of desire would be irrational to have for similar, distinctive reasons that having Moorean beliefs would be irrational to have. (...) Hence, I argue that such desires, a desire that ?one have a particular desire that was frustrated? or a desire that ?some state of affairs obtain about which one was indifferent?, are a parallel Moorean paradox of desire. I further argue that this analogous paradox has implications for practical reasoning, in particular by presenting a problem for instrumentalism about the objects of desire. (shrink)

The paper analyzes the nature and scope of Moore’s paradox, articulates the desiderata of a successful solution and claims that psychological expressivism best meets these desiderata. After a brief discussion of prominent responses to Moore’s paradox, the paper offers a solution based on a theory of expressive acts: a Moorean utterance is absurd because the speaker expresses mental states with conflicting contents in commissive versions of the paradox and conflicting states of mind in omissive versions. The paper presents a (...) theory of expressivism for self-ascriptions of mental states. In addition, it introduces the idea of expressive denegation—the speaker’s expressing the absence of a mental state—as an analysis of negative self-ascriptions of mental states. Some of the consequences of expressivism for avowals are explored. (shrink)

This paper presents an attempt to solve Laura Valentini’s ideal theory paradox, in a way which makes me think of G.E. Moore but I shall leave the classification of the solution to the experts. I also discuss the claim that philosophy is so easy.

A well-known open problem in epistemic logic is to give a syntactic characterization of the successful formulas. Semantically, a formula is successful if and only if for any pointed model where it is true, it remains true after deleting all points where the formula was false. The classic example of a formula that is not successful in this sense is the “Moore sentence” p ∧ ¬BOXp, read as “p is true but you do not know p.” Not only is the (...) Moore sentence unsuccessful, it is self-refuting, for it never remains true as described. We show that in logics of knowledge and belief for a single agent (extended by S5), Moorean phenomena are the source of all self-refutation; moreover, in logics for an introspective agent (extending KD45), Moorean phenomena are the source of all unsuccessfulness as well. This is a distinctive feature of such logics, for with a non-introspective agent or multiple agents, non-Moorean unsuccessful formulas appear. We also consider how successful and self-refuting formulas relate to the Cartesian and learnable formulas, which have been discussed in connection with Fitch’s “paradox of knowability.” We show that the Cartesian formulas are exactly the formulas that are not eventually self-refuting and that not all learnable formulas are successful. In an appendix, we give syntactic characterizations of the successful and the self-refuting formulas. (shrink)

Moore supposedly discovered that there are sentences of a certain form that, though they can be true, no rational human being can sincerely and truly utter any of them. MC and MO are particular instances:MC: “It is raining and I believe that it is not raining”MO: “It is raining and I don’t believe that it is raining”In this paper, I show that there are sentences of the same form as MC and MO that can be sincerely and truly uttered by (...) rational agents. We call sentences of the same form as MC and MO “Moorean Sentences”. In Part II, we go over a standard argument for why sentences of the same form as MC and MO cannot be sincerely and truly uttered, and we explain why this argument is unsound. In explaining why this argument is unsound, we rely on the context-sensitivity of belief-reports and show that the premises of the argument are not all true in the same context. We then employ a general theory of belief reports that incorporates guises to explain why our examples are sincerely utterable while Moore’s sentences are typically not sincerely utterable. The answer will turn on the suggestion that belief reports carry a hidden quantifier over guises, where the domain of quantification is determined by context. We conclude with general lessons about Moore’s Paradox and the supposed limits of first-person belief reports. (shrink)

We outline a novel solution to Moore’s paradox within the framework of update semantics, which explains Moorean absurdity in terms of non-cohesiveness. It is argued that, unlike the outlined solution, Gillies’ treatment of the paradox within this framework is not satisfactory.

Earlier versions of this paper were presented at the University of Virginia and at Texas A&M University. I thank audiences at both institutions for their insightful comments. Special thanks to John Williams for his illuminating comments on an earlier draft.

It has been argued that moral assertions involve the possession, on the part of the speaker, of appropriate non-cognitive attitudes. Thus, uttering ‘murder is wrong’ invites an inference that the speaker disapproves of murder. In this paper, we present the result of 4 empirical studies concerning this phenomenon. We assess the acceptability of constructions in which that inference is explicitly canceled, such as ‘murder is wrong but I don’t disapprove of it’; and we compare them to similar constructions involving ‘think’ (...) instead of ‘disapprove’—that is, Moore paradoxes (‘murder is wrong but I don’t think that it is wrong’). Our results indicate that the former type of constructions are largely infelicitous, although not as infelicitous as their Moorean counterparts. (shrink)

The main task is to discuss the issue in belief dynamics in which philosophical beliefs and rational introspective agents incorporate Moorean type new information. First, a brief survey is conducted on Moore’s Paradox, and one of its solutions is introduced with the help of Update Semantics. Then, we present a Dynamic Doxastic Logic (DDL) which revises the belief of introspective agents put forward by Lindström & Rabinowicz. Next, we attempt to incorporate Moorean type new information within the DEL (...) (DDL) framework, as advised by van Benthem, Segerberg et al. Though we maintain the principle of “the primacy of new information” from the literature on traditional belief revision theory, several unsuccessful ways are also presented. We then conclude that some special kind of success (weak success) can still be found in those revision processes although absolute success does not hold. At last, the relevant problem of “learnability” is re-considered through weak success. (shrink)

Fitch’s Paradox shows that if every truth is knowable, then every truth is known. Standard diagnoses identify the factivity/negative infallibility of the knowledge operator and Moorean contradictions as the root source of the result. This paper generalises Fitch’s result to show that such diagnoses are mistaken. In place of factivity/negative infallibility, the weaker assumption of any ‘level-bridging principle’ suffices. A consequence is that the result holds for some logics in which the “Moorean contradiction” commonly thought to underlie the (...) result is in fact consistent. This generalised result improves on the current understanding of Fitch’s result and widens the range of modalities of philosophical interest to which the result might be fruitfully applied. Along the way, we also consider a semantic explanation for Fitch’s result which answers a challenge raised by Kvanvig. (shrink)

This paper argues that justification is accessible in the sense that one has justification to believe a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. I argue that the accessibility of justification is required for explaining what is wrong with believing Moorean conjunctions of the form, ‘p and I do not have justification to believe that p.’.

G.E. Moore noticed the oddity of statements like: “It's raining, but I don't believe it.” This oddity is often seen as analogous to the oddity of believing akratically, or believing what one believes one should not believe, and has been appealed to in denying the possibility of akratic belief. I describe a Belief Akratic's Paradox, analogous to Moore's paradox and centered on sentences such as: “I believe it's raining, but I shouldn't believe it.” I then defend the possibility of akratic (...) belief against appeals to this analogy, arguing both that akratic belief does not require belief-akratic-paradoxical belief, and that the latter is importantly different from Moorean belief. I conclude by considering the implications of these arguments for an understanding of both Moorean and akratic belief. (shrink)

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.

Epistemic logic in the tradition of Hintikka provides, as one of its many applications, a toolkit for the precise analysis of certain epistemological problems. In recent years, dynamic epistemic logic has expanded this toolkit. Dynamic epistemic logic has been used in analyses of well-known epistemic “paradoxes”, such as the Paradox of the Surprise Examination and Fitch’s Paradox of Knowability, and related epistemic phenomena, such as what Hintikka called the “anti-performatory effect” of Moorean announcements. In this paper, we explore (...) a variation on basic dynamic epistemic logic—what we call sequential epistemic logic—and argue that it allows more faithful and fine-grained analyses of those epistemological topics.

Moore′s paradox came of age when John N. Williams gave us a simple paradoxical argument according to which the Moorean believer must hold false belief while believing contingent propositions. Simplicity was key; it was groundbreaking for the topic. On Williams′s account, given only the notions of inconsistency and self‐refutation, the thesis that belief distributes over conjunction, and a tiny bit of classical logic, we can derive a paradox from the Moorean propositional schemata. But, as argued here, it′s easy (...) to overestimate the significance of his argument to a proper understanding of the problem. His fundamental claim can be established in a way that shows how the paradox arises for any propositional attitude that distributes over conjunction, which gives us the opportunity to reconsider the problem we have been calling “Moore′s paradox”, and to conclude that all of the available analyses of the problem are, at best, incomplete. On this new approach, we lose a little formal simplicity vis‐à‐vis Williams′s approach, but make conceptual economy, as we gain a farther‐reaching problem than the one we have known. (shrink)

Moore’s paradox is the fact that assertions or beliefs such asBangkok is the capital of Thailand but I do not believe that Bangkok is the capital of Thailand or Bangkok is the capital of Thailand but I believe that Bangkok is not the capital of Thailand are ‘absurd’ yet possibly true. The current orthodoxy is that an explanation of the absurdity should first start with belief, on the assumption that once the absurdity in belief has been explained then this will (...) translate into an explanation of the absurdity in assertion. This assumption gives explanatory priority to belief over assertion. I show that the translation involved is much trickier than might at first appear. It is simplistic to think that Moorean absurdity in assertion is always a subsidiary product of the absurdity in belief, even when the absurdity is conceived as irrationality. Instead we should aim for explanations of Moorean absurdity in assertion and in belief that are independent even if related, while bearing in mind that some forms of irrationality may be forms of absurdity even if not conversely.

An analysis of Moore's paradox is given in doxastic logic. Logics arising from formalizations of various introspective principles are compared; one logic, K5c, emerges as privileged in the sense that it is the weakest to avoid Moorean belief. Moreover it has other attractive properties, one of which is that it can be justified solely in terms of avoiding false belief. Introspection is therefore revealed as less relevant to the Moorean problem than first appears.

If I were to say, “Agnes does not know that it is raining, but it is,” this seems like a perfectly coherent way of describing Agnes’s epistemic position. If I were to add, “And I don’t know if it is, either,” this seems quite strange. In this chapter, we shall look at some statements that seem, in some sense, contradictory, even though it seems that these statements can express propositions that are contingently true or false. Moore thought it was paradoxical (...) that statements that can express true propositions or contingently false propositions should nevertheless seem absurd like this. If we can account for the absurdity, we shall solve Moore’s Paradox. In this chapter, we shall look at Moore’s proposals and more recent discussions of Moorean absurd thought and speech. (shrink)

One version of Moore’s Paradox is the challenge to account for the absurdity of beliefs purportedly expressed by someone who asserts sentences of the form ‘p & I do not believe that p’. The absurdity of these beliefs is philosophically puzzling, given that Moorean sentences are contingent and often true; and express contents that are unproblematic when presented in the third-person. In this paper I critically examine the most popular proposed solution to these two puzzles, according to which (...) class='Hi'>Moorean beliefs are absurd because Moorean sentences are instances of pragmatic paradox; that is to say, the propositions they express are necessarily false-when-believed. My conclusion is that while a Moorean belief is a pragmatic paradox, it is not just another pragmatic paradox, because this diagnosis does not explain all the puzzling features of Moorean beliefs. In particularly, while this analysis is plausible in relation to the puzzle posed by characteristic of Moorean sentences, I argue that it fails to account for. I do so in the course of an attempt to formulate the definition of a pragmatic paradox in more precise formal terms, in order to see whether the definition is satisfied by Moorean sentences, but not by their third-person transpositions. For only an account which can do so could address adequately. After rejecting a number of attempted formalizations, I arrive at a definition which delivers the right results. The problem with this definition, however, is that it has to be couched in first-person terms, making an essential use of ‘I’. Thus the problem of accounting for first-/third-person asymmetry recurs at a higher order, which shows that the Pragmatic Paradox Resolution fails to identify the source of such asymmetry highlighted by Moore’s Paradox.

Two proofs are given which show that if some set of truths fall under finitely many concepts (so-called Collectivity), then they all fall under at least one of them even if we do not know which one. Examples are given in which the result seems paradoxical. The first proof crucially involves Moorean propositions while the second is a reconstruction and generalization of a proof due to Humberstone free from any reference to such propositions. We survey a few solution routes (...) including Tennant-style restriction strategies. It is concluded that accepting Collectivity for some set of truths while also denying that any of the involved concepts in isolation capture all of them requires that one of these concepts cannot be closed under conjunction elimination. This is surprising since the paper surveys several applications in which Collectivity and the latter closure condition seemed jointly satisfiable for concepts of actual philosophical interest.

Is there a Moore ’s paradox in desire? I give a normative explanation of the epistemic irrationality, and hence absurdity, of Moorean belief that builds on Green and Williams’ normative account of absurdity. This explains why Moorean beliefs are normally irrational and thus absurd, while some Moorean beliefs are absurd without being irrational. Then I defend constructing a Moorean desire as the syntactic counterpart of a Moorean belief and distinguish it from a ‘Frankfurt’ conjunction of (...) desires. Next I discuss putative examples of rational and irrational desires, suggesting that there are norms of rational desire. Then I examine David Wall’s groundbreaking argument that Moorean desires are always unreasonable. Next I show against this that there are rational as well as irrational Moorean desires. Those that are irrational are also absurd, although there seem to be absurd desires that are not irrational. I conclude that certain norms of rational desire should be rejected. (shrink)

G. E. Moore famously noted that saying 'I went to the movies, but I don't believe it' is absurd, while saying 'I went to the movies, but he doesn't believe it' is not in the least absurd. The problem is to explain this fact without supposing that the semantic contribution of 'believes' changes across first-person and third-person uses, and without making the absurdity out to be merely pragmatic. We offer a new solution to the paradox. Our solution is that the (...) truth conditions of any moorean utterance contradict its accuracy conditions. Thus we diagnose a contradiction in how the moorean utterance represents things as being; so we can do justice to the intuition that a Moore-paradoxical utterance is in some way senseless, even if we know what proposition it expresses.

The aim of this paper is to argue that what I call the simple theory of introspection can be extended to account for our introspective knowledge of what we believe as well as what we consciously experience. In section one, I present the simple theory of introspection and motivate the extension from experience to belief. In section two, I argue that extending the simple theory provides a solution to Moore’s paradox by explaining why believing Moorean conjunctions always involves some (...) degree of irrationality. In section three, I argue that it also solves the puzzle of transparency by explaining why it’s rational to answer the question whether one believes that p by answering the question whether p. Finally, in section four, I defend the simple theory against objections by arguing that self-knowledge constitutes an ideal of rationality. (shrink)

Over the last two decades J.N. Williams has developed an account of the absurdity of such utterances as Its raining but I dont believe it that is both intuitively plausible and applicable to a wide variety of forms that this so-called Moorean absurdity can take. His approach is also noteworthy for making only minimal appeal to principles of epistemic or doxastic logic in its account of such absurdity. We first show that Williams places undue emphasis upon assertion and belief: (...) It is similarly absurd for a person to accept a proposition P as a supposition for the sake of argument while denying that her state of mind is one of supposing P, yet Williams has no account of this. Williams approach is then modified to account for such a case. That modification employs a principle of doxastic logic that is at least plausible as the one on which Williams relies, while being unlike his principle in applying to cases other than belief.

Moore's paradox pits our intuitions about semantic oddnessagainst the concept of truth-functional consistency. Most solutions tothe problem proceed by explaining away our intuitions.

Moore’s paradox in belief is the fact that beliefs of the form ‘ p and I do not believe that p ’ are ‘absurd’ yet possibly true. Writers on the paradox have nearly all taken the absurdity to be a form of irrationality. These include those who give what Timothy Chan calls the ‘pragmatic solution’ to the paradox. This solution turns on the fact that having the Moorean belief falsifies its content. Chan, who also takes the absurdity to be (...) a form of irrationality, objects to this solution by arguing that it is circular and thus incomplete. This is because it must explain why Moorean beliefs are irrational yet, according to Chan, their grammatical third-person transpositions are not, even though the same proposition is believed. But the solution can only explain this asymmetry by relying on a formulation of the ground of the irrationality of Moorean beliefs that presupposes precisely such asymmetry. I reply that it is neither necessary nor sufficient for the irrationality that the contents of Moorean beliefs be restricted to the grammatical first-person. What has to be explained is rather that such grammatical non-first-person transpositions sometimes, but not always, result in the disappearance of irrationality. Describing this phenomenon requires the grammatical first-person/non-first person distinction. The pragmatic solution explains the phenomenon once it is formulated in de se terms. But the grammatical first-person/non-first-person distinction is independent of, and a fortiori, different from, the de se /non- de se distinction presupposed by pragmatic solution, although both involve the first person broadly construed. Therefore the pragmatic solution is not circular. Building on the work of Green and Williams I also distinguish between the irrationality of Moorean beliefs and their absurdity. I argue that while all irrational Moorean beliefs are absurd, some Moorean beliefs are absurd but not irrational. I explain this absurdity in a way that is not circular either. (shrink)

What explanation is there of the source of my justification for my beliefs about my beliefs that respects the fact that I am normally the best authority on them? Moore's paradox demands an explanation of the absurdity of believing or asserting possible truths of the forms p but I don't believe that p or p but I believe that not-p. I argue for Evans principle that whatever justifies me in believing that p also justifies me in believing that I believe (...) that p. This helps explain how I come to know my own beliefs and also shows that it is impossible for a Moorean belief to be justified. I then explain the absurdity of Moorean assertion while avoiding the messy notion of 'expressing belief' yet acknowledging Shoemaker’s constraint that if I cannot non-absurdly believe that p then I cannot non-absurdly assert that p.

Abstract: Moore's sentences of the form "P & ∼I believe that P" and "P & I believe that ∼P" are thought to be paradoxical because they cannot be properly asserted despite being possibly true. Solutions to the paradox usually explain the oddity of such sentences in terms of phenomena as diverse as the pragmatics of speech acts, nature of belief or justification. In this paper I shall argue that despite their seemingly different approaches to the problem, there is a single (...) strategy that underlies all such proposals. Having criticized these suggestions, I shall defend my own solution according to which Moorean sentences are defective not because of some associated logical impropriety but because their assertion violates a certain interpretive constraint, viz., the principle of charity, on an adequate theory of meaning.

We present counterexamples to the widespread assumption that Moorean sentences cannot be rationally asserted. We then explain why Moorean assertions of the sort we discuss do not incur the irrationality charge. Our argument involves an appeal to the dual-process theory of the mind and a contrast between the conditions for ascribing beliefs to oneself and the conditions for making assertions about independently existing states of affairs. We conclude by contrasting beliefs of the sort we discuss with the structurally (...) similar but rationally impermissible beliefs of certain psychiatric patients. (shrink)

In this article, I consider the cases of religious Moorean propositions of the form ‘d, but I don't believe that d’ and ‘d, but I believe that ~d’, where d is a religious dogma, proposition, or part of a creed. I argue that such propositions can be genuinely and rationally asserted and that this fact poses a problem for traditional analysis of religious assertion as an expression of faith and of religious faith as entailing belief. In the article, I (...) explore the possibility of undermining these commonly held assumptions and argue that the assertability of religious Moorean propositions can be justified by an account of faith as an intention to form religious beliefs. In the end, I also consider the consequences of such a stance, especially concerning the debate on the ethics of religious belief and doxastic voluntarism. (shrink)

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually contradictory claims about Moore's Paradox. The two accounts in question are, first, the Action Theory of Belief, the functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion, the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean assertions are (...) absurd, and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are, in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive relationships linking belief, assent and behavioural dispositions.

Influenced by G. E. Moore, Russell broke with Idealism towards the end of 1898; but in later years he characterized his meeting Peano in August 1900 as ?the most important event? in ?the most important year in my intellectual life?. While Russell discovered his paradox during his post-Peano period, the question arises whether he was already committed, during his pre-Peano Moorean period, to assumptions from which his paradox may be derived. Peter Hylton has argued that the pre-Peano Russell was (...) thus vulnerable to (at least one version of) Russell's paradox and hence that the paradox exposes a pre-existing difficulty in Russell's Moorean philosophy. Contrary to Hylton, I argue that the Moorean Russell adhered to views which insulated him against the paradox. Further, I argue that Russell became vulnerable to his paradox as a result of changes in his Moorean position occasioned, first, by his acceptance of Cantor's theory of the transfinite, and, second, by his correspondence with Frege. I conclude with some general comments regarding Russell's acceptance of naïve set theory. (shrink)

A Unified Treatment of Moore's Paradox is the culmination of a decades-long engagement with Moore's paradox by the world's leading authority on the subject, the late John Williams. The book offers a comprehensive account of Moore's paradox in thought and speech, both in its comissive and omissive forms. Williams argues that Moorean absurdity comes in degrees, and shows that contrary to one tradition in the literature on Moore's Paradox, we cannot explain Moorean absurdity in speech in terms of (...) Moorean absurdity in thought, but must account for each form of absurdity in its own terms. Williams also explores the extent to which Moore's paradox may arise for attitudes other than belief, such as desire. Written with Williams' trademark clarity and wit, the book is packed with arguments bearing on a wide range of topics in epistemology, the philosophy of language, and the philosophy of mind.

G.E. Moore famously observed that to say, ‘I went to the pictures last Tuesday but I don’t believe that I did’ or ‘I believe that he has gone out, but he has not’. would be ‘absurd’.

Can there be ‘Moorean desires’, namely desires of the forms I desire (...) both that and I desire both that that are ‘Moore-paradoxical’, in the sense that they are absurd roughly in the way Moore-paradoxical beliefs are absurd? I argue that the most promising approach to a yes is a normative account of doxastic Moore-paradoxicality that parallels a normative account of Moorean desire. It turns out that this won’t work, not because there are no norms of desire, but because the norms required are ones we should reject. Unlike Moorean belief, which is always irrational, Moorean desire, although often odd, is sometimes sensible. An interesting lesson to be learned along the way—and an important one for functionalism—is that the logic of desire differs from that of both conscious belief and belief per se. (shrink)

Unlike first-person Moorean sentences, it’s not always awkward to assert, “p, but you don’t know that p.” This can seem puzzling: after all, one can never get one’s audience to know the asserted content by speaking thus. Nevertheless, such assertions can be conversationally useful, for instance, by helping speaker and addressee agree on where to disagree. I will argue that such assertions also make trouble for the growing family of views about the norm of assertion that what licenses proper (...) assertion is not the initiating epistemic position of the speaker but the resulting epistemic position of the audience.
