The objects of credence are the entities to which credences are assigned for the purposes of a successful theory of credence. I use cases akin to Frege's puzzle to argue against referentialism about credence : the view that objects of credence are determined by the objects and properties at which one's credence is directed. I go on to develop a non-referential account of the objects of credence in terms of sets of epistemically possible scenarios.

In this paper we advance a new solution to Quinn’s puzzle of the self-torturer. The solution falls directly out of an application of the principle of instrumental reasoning to what we call “vague projects”, i.e., projects whose completion does not occur at any particular or definite point or moment. The resulting treatment of the puzzle extends our understanding of instrumental rationality to projects and ends that cannot be accommodated by orthodox theories of rational choice.

In recent literature in the philosophy of mind and language, one finds a variety of examples that raise serious problems for the traditional analysis of belief as a two-term relation between a believer and a proposition. My main purpose in this essay is to provide a critical test case for any theory of the propositional attitudes, and to demonstrate that this case really does present an unsolved puzzle. Chapter I defines the traditional, propositional analysis of belief, and then introduces (...) a distinction, motivated by the intuitions that underlie Kripke's arguments for direct reference, between purely qualitative and individual propositions. Beliefs typically expressed using proper names, indexicals or demonstratives appear to relate the believer to individual propositions with the entity that may be referred to as subject constituent. Chapter II presents the critical test case . In this and Chapters III-VI it is used to show that the latter sorts of beliefs are not analyzable as dyadically relating the believer to individual propositions. The case constitutes a genuine counterexample to the traditional analysis only if it is possible for a believer to believe an individual proposition with a contingent thing other than herself as a constituent; and the believer in the case is in optimum conditions for believing an individual proposition. In Chapters III, IV, and VI, I criticize views prompted by rejection of , and in Chapter V, I criticize Stalnaker's view, which rejects . Chapter VI also considers the non-traditional, triadic analyses of belief proposed by Kaplan and Richard; they fall prey to the main criticisms of Chapter V. In the Postscript, I give a comparative assessment of approaches to resolving the Two Tubes Puzzle, and I place it in historical context by pointing out the puzzle's similarities to the 'problem of sense data' . Correlatively, I indicate the bearing of Methodological Solipsism on future attempts to solve the puzzle. My conclusion is that although the puzzle remains a puzzle, it gives us reason to supplement, rather than completely abandon, the use of propositions in the analysis of thought; and I say what a supplementing solution must do to remain faithful to the intuitions of Chapter I.

Frege's puzzle is a fundamental challenge for accounts of mental and linguistic representation. This piece surveys a family of recent approaches to the puzzle that posit representational relations. I identify the central commitments of relational approaches and present several arguments for them. I also distinguish two kinds of relationism—semantic relationism and formal relationism—corresponding to two conceptions of representational relations. I briefly discuss the consequences of relational approaches for foundational questions about propositional attitudes, intentional explanation, and compositionality.

This paper argues that there is no genuine puzzle of ‘imaginative resistance’. In part 1 of the paper I argue that the imaginability of fictional propositions is relative to a range of different factors including the ‘thickness’ of certain concepts, and certain pre-theoretical and theoretical commitments. I suggest that those holding realist moral commitments may be more susceptible to resistance and inability than those holding non-realist commitments, and that it is such realist commitments that ultimately motivate the problem. However, (...) I argue that the relativity of imaginability is not a particularly puzzling feature of imagination. In part 2, I claim that it is the so-called ‘alethic’ puzzle, concerning fictional truth, which generates a real puzzle about imaginative resistance. However, I argue that the alethic puzzle itself depends on certain realist assumptions about the nature of fictional truth which are implausible and should be rejected in favour of an interpretive view of fictional truth. Once this is done, I contend, it becomes evident that the supposed problem of imaginative resistance as it has hitherto been discussed in the literature is not puzzling at all. (shrink)

Discrimination laws usually prohibit discrimination based on some traits, like race, caste, and sex, and not on others, like sports team allegiance. Should socioeconomic class be included among the protected traits? We examine an argument for the view that it should which leads to the conclusion that both direct and indirect socioeconomic discrimination should be prohibited by the state. The argument has three premises: (1) direct paradigmatic discrimination should be prohibited by law; (2) if direct paradigmatic discrimination should be prohibited (...) by law, then so should direct socioeconomic discrimination; and (3) where direct discrimination based on a certain trait should be prohibited by law, so should indirect discrimination on the basis of the same trait. Since we assume most readers will accept (1), the paper is largely devoted to the defense of (2) and (3). The outlawing of direct socioeconomic discrimination would involve an adjustment of the political and legal status quo, but we argue that it should nevertheless be implemented. By contrast, a prohibition on indirect socioeconomic discrimination would require a radical change to the way in which our societies are structured, because many of our laws, policies, and practices systematically (re)produce inequality to the disproportionate detriment of the poor. Our main aim, therefore, is not to defend the prohibition of indirect socioeconomic discrimination, but to show that most people’s views about discrimination are in deep tension with their attitude to current law. Resolving this tension would require for most of us to revise our beliefs either about whether indirect socioeconomic discrimination should be prohibited or about (1)–(3). One might reject the view that law should prohibit socioeconomic discrimination and still accept this claim about a deep tension in most people’s views on discrimination. (shrink)

In this paper, I offer a solution to the Capacity/Equality Puzzle. The puzzle holds that an account of the franchise may adequately capture at most two of the following: (1) a political equality-based account of the franchise, (2) a capacity-based account of disenfranchising children, and (3) universal adult enfranchisement. To resolve the puzzle, I provide a complex liberal egalitarian justification of a moral requirement to disenfranchise children. I show that disenfranchising children is permitted by both the proper (...) political liberal and the proper political egalitarian understandings of the relationship between cognitive capacity and the franchise. Further, I argue, disenfranchising children is required by a minimalistic, procedural principle of collective competence in political decision-making. At the same time, I show that political equality requires the enfranchisement of all adults, regardless of cognitive capacities, and that the collective competence principle does not ground adult disenfranchisement. This justifies the progressive legal trend that holds the capacity-based disenfranchisement of adults to be incompatible with liberal democratic principles. (shrink)

This essay review explores Steven Mithen’s interdisciplinary approach to the origins and evolution of language in _The Language Puzzle_ ( 2024 ). It focuses mainly on what I call his _iconic vocal origins hypothesis_. Mithen challenges the prevalent gestural origins hypothesis, suggesting instead that early prehistoric languages were predominantly vocal and iconic, with conventionalization – as characteristic of symbol use – emerging later. _The Language Puzzle_ draws on research from archaeology, philosophy, computer science, developmental psychology, and many other fields, thus (...) assembling a wealth of insights from various disciplines. While intriguing, Mithen’s suggestion that prehistoric languages may have relied on iconicity instead of conventionalization faces substantial problems, which are discussed in this review essay. In the final section, I also briefly review the important conclusion chapter of Mithen’s book, which contains an imaginative outline of how language evolved from the last common ancestor up until modern _H. sapiens._ My criticisms of the iconic vocal origins hypothesis notwithstanding, _The Language Puzzle_ is a valuable resource for anyone interested in language evolution, and once again showcases Mithen’s wide-ranging expertise and masterful writing.

Raffaella De Rosa discusses the theory of sensory perception, especially color perception, offered by Ren Descartes. She offers a detailed overview of the recent literature on the topic and provides a new reading of Descartes' theory; she also raises questions of great interest in the contemporary philosophy of mind and cognitive science.

This paper argues against the common practice of presenting perdurantism, endurantism, and other views about persistence and time as solutions to an alleged puzzle about change. Various recent attempts to generate a puzzle about change are examined and found unsuccessful. This does not mean, however, that the relevant views about persistence and time are not well motivated, but rather that their interest and purpose is independent of their suitability for solving the alleged puzzle.

Confronting the threat of a Spinozistic necessitarianism, Leibniz insists that not all possible substances are compossible—that they can't all be instantiated together—and thus that not all possible worlds are compossible—that they can't all be instantiated together. While it is easy to appreciate Leibniz's reasons for embracing this view, it has proven difficult to see how his doctrine of incompossibility might be reconciled with the broader commitments of his larger philosophical system. This essay develops, in four sections, a novel solution to (...) the "puzzle of incompossibility." The first section frames the difficulty more carefully and briefly argues that the two dominant strategies developed by Leibniz's commentators fail to solve it fully insofar as they require simply abandoning one or another of its motivating commitments. The second and third sections show how Leibniz's guiding analogy of a geometrical packing or tiling problem may be applied to solve the puzzle of incompossibility in the context of finite and infinite worlds composed of extended corporeal substances. Finally, the fourth section shows how the strategy of Leibniz's packing analogy might be applied even in the context of a thoroughly idealist metaphysics in which the only true substances are nonextended, mindlike "monads." The essay concludes by drawing some connections between Leibniz's thinking about the puzzle of incompossibility and the development of his views concerning the status of corporeal substances and extended bodies.

According to Russellianism (or Millianism), the two sentences ‘Ralph believes George Eliot is a novelist’ and ‘Ralph believes Mary Ann Evans is a novelist’ cannot diverge in truth-value, since they express the same proposition. The problem for the Russellian (or Millian) is that a puzzle of Kaplan’s seems to show that they can diverge in truth-value and that therefore, since the Russellian holds that they express the same proposition, the Russellian view is contradictory. I argue that the standard Russellian (...) appeal to “ways of thinking” or “propositional guises” is not necessary to solve the puzzle. Rather than this retrograde concession to Fregeanism, appeal should be made to second-order belief. The puzzle is solved, and the contradiction avoided, by maintaining that both sentences are indeed true in addition to the sentence ‘Ralph (mistakenly) believes that he does not believe Mary Ann Evans/George Eliot is a novelist’.

So-called 'Frege cases' pose a challenge for anyone who would hope to treat the contents of beliefs (and similar mental states) as Russellian propositions: It is then impossible to explain people's behavior in Frege cases without invoking non-intentional features of their mental states, and doing that seems to undermine the intentionality of psychological explanation. In the present paper, I develop this sort of objection in what seems to me to be its strongest form, but then offer a response to it. (...) I grant that psychological explanation must invoke non-intentional features of mental states, but it is of crucial importance which such features must be referenced. -/- It emerges from a careful reading of Frege's own view that we need only invoke what I call 'formal' relations between mental states. I then claim that referencing such 'formal' relations within psychological explanation does not undermine its intentionality in the way that invoking, say, neurological features would. The central worry about this view is that either (a) 'formal' relations bring narrow content in through back door or (b) 'formal' relations end up doing all the explanatory work. Various forms of each worry are discussed. The crucial point, ultimately, is that the present strategy for responding to Frege cases is not available either to the 'psycho-Fregean', who would identify the content of a belief with its truth-value, nor even to someone who would identify the content of a belief with a set of possible worlds. It requires the sort of rich semantic structure that is distinctive of Russellian propositions. There is therefore no reason to suppose that the invocation of 'formal' relations threatens to deprive content of any work to do. (shrink)

We present the simplest solution ever to 'the hardest logic puzzle ever'. We then modify the puzzle to make it even harder and give a simple solution to the modified puzzle. The final sections investigate exploding god-heads and a two-question solution to the original puzzle.

How does evolutionary biology fit with Thomas Kuhn's famous distinction between puzzle solving and paradigm shifts in science?

In this paper, I present a puzzle about epistemic rationality. It seems plausible that it should be rational to believe a proposition if you have sufficient evidential support for it. It seems plausible that it rationality requires you to conform to the categorical requirements of rationality. It also seems plausible that our first-order attitudes ought to mesh with our higher-order attitudes. It seems unfortunate that we cannot accept all three claims about rationality. I will present three ways of trying (...) to resolve this tension and argue that the best way to do this is to reject the idea that strong evidential support is the stuff rationality is made of. In the course of doing this, I shall argue that there is a special class of propositions about the requirements of rationality that we cannot make rational mistakes about and explain how this can be.

This book constructs a new scientific explanation of the causes of war. The author describes systematically those factors common to wars between equal states to see if there is a pattern that suggests why war occurs and delineates the typical path by which relatively equal states have become embroiled in wars with one another in the modern global system. The book differs from others in that it employs the large number of empirical findings generated in the past twenty-five years to (...) solve the puzzle of war and peace. (shrink)

A new research programme conceives of consciousness as a natural kind. One proposed virtue of this approach is that it can help resolve the methodological puzzle of consciousness, which involves distinguishing consciousness from cognitive access. The present article raises a novel problem for this approach. The problem is rooted in the fact that there may be episodes of conscious experience that have not been classified as such. I argue that conceiving of consciousness as a natural kind cannot distinguish consciousness (...) from cognitive access. (shrink)

What are things like the Supreme Court? Gabriel Uzquiano has defended that they are groups, entities which are somehow composed of members (at certain times) but which, unlike sets (or pluralities), allow for fluctuation in membership. The main alternative holds that 'the Supreme Court' refers (at any time) to the set (or plurality) of their members (at the time). Uzquiano motivates his view by posing a metaphysical puzzle for this reductive alternative. I argue that a parallel reasoning would also (...) find a corresponding 'puzzle' in the case of singular terms like 'The Chief Supreme Court Justice'. (shrink)

Coercion by the recipient of consent renders that consent invalid. But what about when the coercive force comes from a third party, not from the person to whom consent would be proffered? In this paper I analyze how threats from a third party affect consent. I argue that, as with other cases of coercion, we should distinguish threats that render consent invalid from threats whose force is too weak to invalidate consent and threats that are legitimate. Illegitimate controlling third party (...) threats render consent invalid just as they do in two party cases. However, knowing that the consent is invalid is not sufficient to tell the recipient of consent what she may or should do. I argue that when presented with a token of consent from someone whom she thinks is experiencing an illegitimate controlling threat, the recipient may act on that token if and only if doing so represents a reasonable joint decision for her and the victim of coercion. The appropriate action for someone faced with third party coercion therefore depends on the other options open to her and those open to the victim of coercion. (shrink)

One of the unresolved issues in Aristotle’s hylomorphism is the part-whole puzzle. Some scholars suppose that in Metaphysics Z 17, 1041b11-33 he endorses non-mereological hylomorphism. This kind of interpretation, however, has been challenged by K. Koslicki who argues that if the evidence in Metaphysics Z 17 is combined with some related textual and conceptual considerations, then a convincing case can be made for a mereological construal of Aristotelian hylomorphism. This paper does four things. First, it scrutinizes these opposing approaches (...) to Aristotle’s theory. Second, it suggests that to adjudicate the dispute at hand one ought to determine how Aristotle deals with what has come to be known as ‘Ackrill’s problem’. It is proposed that if we consider Aristotle’s theory in light of some distinctions drawn in contemporary discussions of hylomorphism, then it transpires that he does have a solution to Ackrill’s problem. Third, it is shown that his solution to this problem suggests a particular way of settling the debate over the part-whole puzzle. And finally, it is argued that the suggested reconstruction of Aristotelian hylomorphism is consistent with the textual evidence in Metaphysics Z 17 and its associated texts. (shrink)

The missing piece of the puzzle: the discovery of the Higgs boson On July 4, 2012 the CMS and ATLAS collaborations at the large hadron collider jointly announced the discovery of a new elementary particle, which resembled the Higgs boson, the last remaining undiscovered piece of the standard model of elementary particles. Both groups claimed to have observed a five-standard-deviation effect above background, the gold standard for discovery in high-energy physics. In this essay I will briefly discuss the how (...) the CMS collaboration performed the experiment and analyzed the data. I will also show the experimental results. (shrink)

In this paper, I present a puzzle that arises if we accept i) that knowledge is more valuable than mere true belief and ii) that whether a person counts as knowing is dependent upon a context-sensitive epistemic standard. Roughly, the puzzle is that if both claims are true, then we should always seek to keep the epistemic standard as low as possible, contrary to what seems like appropriate epistemic behaviour. I consider and reject a number of different ways (...) of avoiding this consequence before presenting my own solution to the puzzle: that any view that posits a context-sensitive epistemic standard must relativize epistemic value as well.

How should we understand the epistemic role of perception? According to epistemological disjunctivism (ED), a subject’s perceptual knowledge that p is to be explained in terms of the subject believing that p for a factive and reflectively accessible reason. I argue that ED raises far-reaching questions for rationality and deliberation; I illustrate those questions by setting up a puzzle about belief-suspension, and I argue that ED does not have the resources to make sense of the rationality of belief-suspension in (...) cases in which suspending is clearly rational. The conclusion that I draw from the puzzle is mainly negative: the epistemic contribution of perception cannot be explained in terms of a warrant-conferring relation between perception and belief. However, toward the end, I sketch a positive picture of the epistemic role of perception in terms of a direct explanatory relation between perception and knowledge. (shrink)

What licenses the use of a definite description? The formal and philosophical literature has approached this question in two ways. The uniqueness approach (Frege, 1892; Russell, 1905; Strawson, 1950) holds that we may use a definite determiner only if the property denoted by its complement holds of exactly one individual in some domain: Sentence (1) and (2) can only be true if there is exactly one king of France, and exactly one American governor, respectively. Since this is not the case (...) in the actual world, the sentences are either false or (on most modern accounts) fall prey to a presupposition failure. (shrink)

In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because these (...) would have to be non-physical sense data. They might instead explain this by saying that BIV “phenomenally represents” various shape properties. But since BIV lacks any interesting physical relations to shapes, this would imply that phenomenally representation is an irreducible relation. (shrink)

This paper considers the problems that arise when death, which is a philosophically difficult concept, is incorporated into healthcare metrics, such as the quality-adjusted life year (QALY). These problems relate closely to the debate over euthanasia and assisted suicide because negative QALY scores can be taken to mean that patients would be ‘better off dead’. There is confusion in the literature about the meaning of 0 QALY, which is supposed to act as an ‘anchor’ for the surveyed preferences on which (...) QALYs are based. In the context of the debate over euthanasia, the QALY assumes an ability to make meaningful comparisons between life-states and death. Not only is this assumption questionable, but the ethical debate is much more broad than the question of whether death is preferable to a state of living. QALYs are derived from preferences about health states, so do not necessarily reflect preferences about events (eg, dying) or actions (eg, killing). This paper presents a new kind of problem for the QALY. As it stands, the QALY provides confused and unreliable information when it reports zero or negative values, and faces further problems when it appears to recommend death. This should preclude its use in the debate over euthanasia and assisted suicide. These problems only apply where the QALY involves or seems to involve a comparison between life-states and death, and are not relevant to the more general discussion of the use of QALYs as a tool for comparing the benefits derived from treatment options.

Gottlob Frege maintained that two name-containing identity sentences, represented schematically as a=a and a=b,can both be true in virtue of the same object’s self-identity but nonetheless, puzzlingly, differ in their epistemic profiles. Frege eventually resolved his puzzlement by locating the source of the purported epistemic difference between the identity sentences in a difference in the Sinne, or senses, expressed by the names that the sentences contain. -/- Thus, Frege portrayed himself as describing a puzzle that can be posed prior (...) to and independently of any particular theoretical position regarding names, and then resolving that puzzle with his theory of Sinn and Bedeutung. In this paper, I suggest that Frege’s presentation is problematic. If attempt is made to characterize the epistemic status of true identity sentences without appeal to Frege’s theoretical commitments, then what initially seemed puzzling largely dissolves. It turns out that, in order to generate puzzlement, Frege must invoke the theoretical account that he uses the puzzle to establish the purported necessity of. (shrink)
