How is it that a speaker _S_ can at once make it obvious to an audience _A_ that she intends to communicate some proposition _p_, and yet at the same time retain plausible deniability with respect to this intention? The answer is that _S_ can bring it about that _A_ has a high justified credence that ‘_S_ intended _p_’ without putting _A_ in a position to know that ‘_S_ intended _p_’. In order to achieve this _S_ has to exploit a (...) sense in which communication can be lottery-like. After defending this view of deniability I argue that it compares favorably to a rival account recently developed by Dinges and Zakkou (Mind, https://doi.org/10.1093/mind/fzac056, 2023 ). (shrink)

Kendall Walton explains pictures in terms of games of perceptual make-believe. Pictures or depictions are props that draw us to participate in games of make-believe where we imagine seeing what a picture depicts. Walton proposes that one imagines of one’s perceptual experience of the coloured canvas that it is a different perceptual experience. The issue is whether perception and imagination can combine the way Walton suggests. Can one imagine a perception to be different? To get a clearer understanding of the (...) unified perceptual-imaginative experience Walton posits, the paper turns to competing theories that explain perceptual experience in terms of contents, relations to objects, or both contents and relations. Walton appeals to theories of perceptual content and cognitive penetration. But it is also important to examine whether his view fits with recent theories that explain perception only in terms of relations or in terms of both contents and relations. The paper argues that Walton’s view is compatible with content theories of perception and can be defended from some objection once we look at the detail these theories offer. Walton’s view is not compatible with pure relational theories of perception but it can be explained by hybrid content-relational theories of perception that posit de re senses. (shrink)

This paper presents a puzzle about justification and withholding. The puzzle arises in a special case where experts advise us to not withhold judgment. My main thesis is simply that the puzzle is genuinely a puzzle, and so leads us to rethink some common assumptions in epistemology, specifically assumptions about the nature of justification and doxastic attitudes. Section 1 introduces the common assumptions. Section 2 presents the puzzle case. Section 3 assesses the puzzle case. (...) Section 4 explains the choice we're faced with. Sections 5 and 6 consider and reject some proposed solutions, and in the process refine and clarify the choice we're faced with. Section 7 considers and rejects a miscellany of different proposed solutions. (shrink)

In this introduction we explore a number of puzzles that arise concerning epistemic autonomy, and introduce the sections and chapters of the book. There are four broad types of puzzles to be explored, corresponding to the four sections of the book. The first set of puzzles concerns the nature of epistemic autonomy. Here, questions arise such as what is epistemic autonomy? Is epistemic autonomy valuable? What are we epistemically autonomous about? The second set of puzzles concern epistemic paternalism. Paternalistic acts (...) interfere with an agent’s autonomy. Here, questions arise concerning the permissibility of epistemic paternalism as well the extension of epistemically paternalistic acts. The third set of puzzles concerns the relation of epistemic autonomy to epistemic value and to intellectual virtues and vices. Is there epistemic value to being epistemically autonomous? How does epistemic autonomy relate to different intellectual virtues and vices? Finally, the fourth set of puzzles concerns the role of epistemic autonomy within a social epistemology. How does epistemic autonomy square with a reliance on expertise? Does thinking about epistemic autonomy add to the debates about the epistemic significance of disagreement or epistemic injustice?

In examining the puzzle of experience, and its possible solutions, Valberg discusses relevant views of Hume, Kant, Heidegger, Wittgenstein, and Strawson, as well as ideas from the recent philosophy of perception. Finally, he describes and analyzes a manifestation of the puzzle outside philosophy, in everyday experience.

Despite the problems students often have with the theory of knowledge, it remains, necessarily, at the core of the philosophical enterprise. As experienced teachers know, teaching epistemology requires a text that is not only clear and accessible, but also capable of successfully motivating the abstract problems that arise.In Knowledge Puzzles, Stephen Hetherington presents an informal survey of epistemology based on the use of puzzles to illuminate problems of knowledge. Each topic is introduced through a puzzle, and readers are invited (...) to work their own ways toward a solution. Hetherington’s light and undogmatic style encourages class discussion and independent thought rather than the memorization of “book” answers.Covering all of the most important epistemological issues, informed by classical and contemporary literature, and rich in probing questions and suggestions for further readings, Knowledge Puzzles is a pedagogical breakthrough. Whether it is used as a main text or supplement, this lucid and engaging text will be welcomed by both teachers and students. (shrink)

Most of our best scientific descriptions of the world employ rates of change of some continuous quantity with respect to some other continuous quantity. For instance, in classical physics we arrive at a particle’s velocity by taking the time-derivative of its position, and we arrive at a particle’s acceleration by taking the time-derivative of its velocity. Because rates of change are defined in terms of other continuous quantities, most think that facts about some rate of change obtain in virtue of (...) facts about those other continuous quantities. For example, on this view facts about a particle’s velocity at a time obtain in virtue of facts about how that particle’s position is changing at that time. In this paper we raise a puzzle for this orthodox reductionist account of rate of change quantities and evaluate some possible replies. We don’t decisively come down in favour of one reply over the others, though we say some things to support taking our puzzle to cast doubt on the standard view that spacetime is continuous. (shrink)

It is a fundamental feature of language that words refer to things. Much attention has been devoted to the nature of reference, both in philosophy and in linguistics. Puzzles of Reference is the first book to give a comprehensive accessible survey of the fascinating work on this topic from the 1970s to the present day. -/- Written by two eminent philosophers of language, Puzzles of Reference offers an up-to-date introduction to reference in philosophy and linguistics, summarizing ideas such as Kripke's (...) revolutionary theory and presenting the various challenges in a clear and accessible manner. As the text does not assume prior training in philosophy or linguistics, it is ideal for use as part of a philosophy of language course for philosophy students or for linguistics students. -/- Puzzles of Reference belongs to the series Contemporary Introductions to Philosophy of Language, in which each book provides an introduction to an important area of the philosophy of language, suitable for students at any level.

To surmount the notorious difficulties of defining life, we should evaluate theories of life not by whether they provide necessary and sufficient conditions for our current preconceptions about life but by how well they explain living phenomena and how satisfactorily they resolve puzzles about life. On these grounds, the theory of life as supple adaptation (Bedau 1996) gets support from its natural and compelling resolutions of the following four puzzles: (1) How are different forms of life at different levels of (...) the vital hierarchy related? (2) Is there a continuum between life and non-life? (3) Does life essentially concern a living entity’s material composition or its form? (4) Are life and mind intrinsically connected? (shrink)

The puzzle of imaginative desire arises from the difficulty of accounting for the surprising behaviour of desire in imaginative activities such as our engagement with fiction and our games of pretend. Several philosophers have recently attempted to solve this puzzle by introducing a class of novel mental states—what they call desire-like imaginings or i-desires. In this paper, I argue that we should reject the i-desire solution to the puzzle of imaginative desire. The introduction of i-desires is both (...) ontologically profligate and unnecessary, and, most importantly, fails to make sense of what we are doing in the imaginative contexts in question.

According to the received view in the literature on homonymy and polysemy representation, there is a difference between how polysemes and homonyms are represented in our mental lexicons. More concretely, the received view holds that whereas the meanings associated with a homonymous expression are (mentally) represented in separate lexical entries, the meanings associated with a polysemous expression are represented together in a single lexical entry. It is usually argued that this is the picture that is supported by the growing body (...) of empirical evidence coming from psycholinguistics. Empirical studies of ambiguity processing and resolution consistently show that polysemous expressions enjoy various processing advantages compared to homonyms, and the received view is generally taken to be required in order to explain these results. The aim of this paper is not only to show that this is not the case but also, and more fundamentally, that the received view falls far short of explaining the available data to a sufficient degree. As a result, the received view is caught up in an explanatory dilemma that I dub the Continuum Puzzle. I then claim that the best way to escape this puzzle is to give up the received view’s core thesis in favor of an alternative view consistent with the empirical evidence. Reaching such an alternative will require rejecting the following pervasive but ill-motivated assumption: Differences in ambiguity processing and resolution can only be explained by there being some corresponding differences in the architecture of our mental lexicons.

The “puzzle of the unmarked clock” derives from a conflict between the following: (1) a plausible principle of epistemic modesty, and (2) “Rational Reflection”, a principle saying how one’s beliefs about what it is rational to believe constrain the rest of one’s beliefs. An independently motivated improvement to Rational Reflection preserves its spirit while resolving the conflict.

Conscious experience is at once the most familiar thing in the world and the most mysterious. There is nothing we know about more directly than consciousness, but it is extraordinarily hard to reconcile it with everything else we know. Why does it exist? What does it do? How could it possibly arise from neural processes in the brain? These questions are among the most intriguing in all of science.

In this paper I will present a puzzle about visual appearance. There are certain necessary constraints on how things can visually appear. The puzzle is about how to explain them. I have no satisfying solution. My main thesis is simply that the puzzle is a puzzle. I will develop the puzzle as it arises for representationalism about experience because it is currently the most popular theory of experience and I think it is along the right (...) lines. However, everyone faces a form of the puzzle, including the naïve realist. In §1 I explain representationalism about experience. In §§2-3 I develop the puzzle and criticize a response due to Ned Block and Jeff Speaks and another response based on a novel form of representationalism (“sensa representationalism”). In §4 I argue that defenders of “perceptual confidence” (Morrison, Munton, my earlier self) face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

In this paper I will present a puzzle about epistemic akrasia, and I will use that puzzle to motivate accepting some non-standard views about the nature of epistemological judgment. The puzzle is that while it seems obvious that epistemic akrasia must be irrational, the claim that epistemic akrasia is always irrational amounts to the claim that a certain sort of justified false belief—a justified false belief about what one ought to believe—is impossible. But justified false beliefs seem (...) to be possible in any domain, and it’s hard to see why beliefs about what one ought to believe should be an exception. I will argue that when we get clearer about what sort of psychological state epistemic akrasia is, we can resolve the puzzle in favor of the intuitive view that epistemic akrasia is always irrational.

This paper concerns Kripke’s puzzle about belief. I have two goals in this paper. The first is to argue that two leading approaches to Kripke’s puzzle, those of Lewis and Chalmers, are inadequate as they stand. Both approaches require the world to supply an object that the relevant intentional attitudes pick out. The problem is that there are cases which, I argue, exhibit the very same puzzling phenomenon in which the world does not supply an object in the (...) required way. The second goal is to draw out a more general lesson about Kripke’s puzzle. I argue that Kripke’s puzzle should be understood as intimately related to a phenomenon known as ‘intentional identity’, and that an adequate account of Kripke’s puzzle should be extensible to cases in which the relevant attitudes are empty.

Mereological nihilism is the view that no objects have proper parts. Despite how counter‐intuitive it is, it is taken quite seriously, largely because it solves a number of puzzles in the metaphysics of material objects – or so its proponents claim. In this article, I show that for every puzzle that mereological nihilism solves, there is a similar puzzle that (a) it doesn’t solve, and (b) every other solution to the original puzzle does solve. Since the solutions (...) to the new puzzles apply just as well to the old puzzles, the old puzzles provide no motivation to be a mereological nihilist. (shrink)

This paper proposes a novel conception of mental files, aimed at addressing Frege puzzles. Classical Frege puzzles involve ignorance and discovery of identity. These may be addressed by accounting for a more basic way for identity to figure in thought—the treatment of beliefs by the believer as being about the same thing. This manifests itself in rational inferences that presuppose the identity of what the beliefs are about. Mental files help to provide a functional characterization of a mind capable of (...) this presupposition, but more must be said to show how it may be rational. I argue that this can be done by drawing out the way in which mental files interact with a thinker's motivational states and so come to have normative functional properties. I show how this theory works better than some other treatments of mental files. (shrink)

In this paper, I present a possible solution to the puzzle unveiled by Kornblith about the sources and the possibility of knowledge of epistemic norms. The puzzle is: if such norms cannot be discovered solely by reflection, and if there are correct ways of thinking and inferring, then such norms can only be discovered by investigating the world —a counterintuitive conclusion. To avoid skepticism about normativity, I argue that we create normative correctness and discover normative demands by investigating (...) the world and reflecting about our epistemic practices. This is done by an exposition of the method known as reflective equilibrium, which is defended against Kornblith’s thesis that the appeal to reflective equilibrium is doomed to failure because it implies reflection.

The puzzle of cross-modal shape experience is the puzzle of reconciling the apparent differences between our visual and haptic experiences of shape with their apparent similarities. This paper proposes that we can resolve the cross-modal puzzle by reflecting on another puzzle. The puzzle of perspectival character challenges us to reconcile the variability of shape experience through shifts in perspective with its constancy. An attractive approach to the latter puzzle holds that shape experience is complex, (...) involving both perspectival aspects and constant aspects. I argue here that parallel distinctions between perspectival and constant aspects of shape experience arise in sight and touch, and that perspectival aspects are modality-specific while at least some constant aspects are constitutively multisensory. I then address a powerful challenge to the idea that aspects of spatial phenomenology are shared cross-modally. (shrink)

The social world contains institutions, groups, objects, and more. This essay explores a puzzle about the essences of social items. There is widespread consensus against social essences because of problematic presuppositions often made about them. But it is argued that essence can be freed from these presuppositions and their problems. Even so, a puzzle still arises. In a Platonic spirit, essences in general seem detached from the world. In an Aristotelian spirit, social essences in particular seem embedded in (...) the world. The puzzle is that these inclinations are individually plausible but jointly incompatible. The essay has four aims: to clarify and refine the puzzle; to explore the puzzle's implications for essence in general and for social essences in particular; to illustrate the fruitfulness of the general distinction between detached and embedded; and to develop this distinction to sketch a novel solution to the puzzle.

Inquiry is guided, in the minimal sense that it is not haphazard. It is also often thought to have as a natural stopping point ceasing to inquire, once inquiry into a question yields knowledge of an answer. On this picture, inquiry is both telic and guided. By contrast, mind-wandering is unguided and atelic, according to the most extensively developed philosophical theory of it. This paper articulates a puzzle that arises from this combination of claims: there seem to be plenty (...) of examples of inquiry progressing within mind-wandering, yet theories of inquiry and mind-wandering can make wandering inquiry seem impossible or incoherent. I offer several solutions to this puzzle and make the case that taken together, they illuminate a prevalent form of inquiry that the burgeoning literature on that topic overlooks: inquiry that progresses spontaneously.

It is commonly accepted that people can, and regularly do, deceive themselves. Yet closer examination reveals a set of conceptual puzzles that make self-deception difficult to explain. Applying the conditions for other-deception to self-deception generates what are known as the ‘paradoxes’ of belief and intention. Simply put, the central problem is how it is possible for me to believe one thing, and yet intentionally cause myself to simultaneously believe its contradiction. There are two general approaches taken by philosophers to account (...) for these puzzles about the self-deceptive state and the process of self-deception. ‘Partitioning’ strategies try to resolve the paradoxes by proposing that the mind is divided in some way that allows self-deception to occur. ‘Reformulation’ strategies suggest that the conditions we use to define self-deception should be modified so that the paradoxes do not arise at all. Both approaches are subject to criticism about the consequences of the strategies philosophers use, but recent cross-disciplinary analyses of self-deception may help shed light on the puzzles that underlie this phenomenon.

According to the transparency approach, achievement of self-knowledge is a two-stage process: first, the subject arrives at the judgment ‘p’; second, the subject proceeds to the judgment ‘I believe that p.’ The puzzle of transparency is to understand why the transition from the first to the second judgment is rationally permissible. After revisiting the debate between Byrne and Boyle on this matter, I present a novel solution according to which the transition is rationally permissible in virtue of a justifying (...) argument that begins from a premise referring to the mental utterance that is emitted in the course of judging ‘p.’.

This is the 1991 (2nd) edition of the 1986 book (MIT Press), considered to be the classic defense of Millianism. The nature of the information content of declarative sentences is a central topic in the philosophy of language. The natural view that a sentence like "John loves Mary" contains information in which two individuals occur as constituents is termed the naive theory, and is one that has been abandoned by most contemporary scholars. This theory was refuted originally by philosopher Gottlob (...) Frege. His argument that the naive theory did not work is termed Frege's puzzle, and his rival account of information content is termed the orthodox theory. In this detailed study, Nathan Salmon defends a version of the naive theory and presents a proposal for its extension that provides a better picture of information content than the orthodox theory gives. He argues that a great deal of what has generally been taken for granted in the philosophy of language over the past few decades is either mistaken or unsupported, and consequently, much current research is focused on the wrong set of questions. Salmon dissolves Frege's puzzle as it is usually formulated and demonstrates how it can be reconstructed and strengthened to yield a more powerful objection to the naive theory. He then defends the naive theory against the new Frege puzzle by presenting an idea that yields both a surprisingly rich and powerful extension of the naive theory and a better picture of information content than that of the original orthodox theory. Nathan Salmon is Professor of Philosophy, University of California at Santa Barbara. (shrink)

A famous mathematical theorem says that the sum of an infinite series of numbers can depend on the order in which those numbers occur. Suppose we interpret the numbers in such a series as representing instances of some physical quantity, such as the weights of a collection of items. The mathematics seems to lead to the result that the weight of a collection of items can depend on the order in which those items are weighed. But that is very hard (...) to believe. A puzzle then arises: How do we interpret the metaphysical significance of this mathematical theorem? I first argue that prior solutions to the puzzle lead to implausible consequences. Then I develop my own solution, where the basic idea is that the weight of a collection of items is equal to the limit of the weights of its finite subcollections contained within ever-expanding regions of space. I show how my solution is intuitively plausible and philosophically motivated, how it reveals an underexplored line of metaphysical inquiry about quantities and locations, and how it elucidates some classic puzzles concerning supertasks.

Imagine your mirror‐inverted counterpart on Mirror Earth, a perfect mirror image of Earth. Would her experiences be the same as yours, or would they be phenomenally mirror‐inverted? I argue, first, that her experiences would be phenomenally the same as yours. I then show that this conclusion gives rise to a puzzle, one that I believe pushes us toward some surprising and philosophically significant conclusions about the nature of perception. When you have a typical visual experience as of something to (...) your left, the following three claims seem very plausible: (1) No one could have an experience phenomenally just like yours without thereby having an experience as of something to her left. (2) Your experience is veridical. (3) Your experience doesn't differ from that of your mirror‐inverted counterpart with respect to veridicality. But (1)‐(3) jointly contradict the claim that you and your mirror‐inverted counterpart would have the same experiences. I argue that any viable response to this puzzle will embrace the following disjunction: either there is a degree of independence between perceptual phenomenology and representational content, contrary to popular intentionalist views of perception, or spatial subjectivism is true, where spatial subjectivism is the view that the spatial properties presented in perception are either mind‐dependent or illusory.

The purpose of this paper is to present and discuss a puzzle involving accommodation. The puzzle is based on three assumptions. The first assumption is that accommodation takes place after an utterance. The second assumption is that accommodation can make a difference to the truth-value of an utterance even if the utterance is not about the future. The third assumption is that something that takes place after an utterance cannot make a difference to the truth-value of the utterance (...) unless the utterance is about the future. Since these assumptions are jointly inconsistent, one of them must be false. The question is which one we ought to reject. The majority of the discussion is devoted to discussing each of the options, and the tentative conclusion is that the most plausible strategy is to reject the third thesis. That amounts to saying that something that takes place after an utterance can make a difference to the truth-value of the utterance even if the utterance is not about the future. (shrink)

Much of our know-how is acquired through practice: we learn how to cook by cooking, how to write by writing, and how to dance by dancing. As Aristotle argues, however, this kind of learning is puzzling, since engaging in it seems to require possession of the very knowledge one seeks to obtain. After showing how a version of the puzzle arises from a set of attractive principles, I argue that the best solution is to hold that knowledge-how comes in (...) degrees, and through practice a person gradually learns how to do something. However, the two standard accounts of know-how in the literature, intellectualism and anti-intellectualism, cannot properly account for the distinctive way in which know-how is gradually acquired by practice, a process in which conceptual representations and practical abilities are intimately interwoven. Drawing on Gareth Evans's work, I outline an account that may do so, and use this account to distinguish between two forms of learning to explain why skill generally cannot be learnt through testimony, and requires practice.

The essay is a partial investigation into the semantics of the explanatory connective ‘because’. After three independently plausible assumptions about ‘because’ are presented in some detail, it is shown how their interaction generates a puzzle about ‘because’, once they are combined with a common view on conceptual analysis. Four possible solutions to the puzzle are considered.

Sainsbury and Tye present a new theory, 'originalism', which provides natural, simple solutions to puzzles about thought that have troubled philosophers for centuries. They argue that concepts are to be individuated by their origin, rather than epistemically or semantically. Although thought is special, no special mystery attaches to its nature.

The Covid-19 pandemic has brought to surface new and puzzling manifestations of the culture wars between liberals and conservatives, especially in the US. One such manifestation is the one centered around mask-wearing as a way to protect others from viral infection. In public spaces, mask-wearing has become a signal as to whether one is a liberal or a conservative. Liberals tend to wear the mask and condemn as immoral conservatives, who tend not to wear it. I argue that the liberal (...) attitude does not cohere with liberal theory. I use the issue of the permissibility of abortion and the liberal consensus about it as the benchmark for what a genuine liberal attitude toward mask-wearing should be. (shrink)

Argues for a failure of correspondence between perceptual representation and what it is like to perceive. If what it is like to perceive is grounded in perceptual representation, then, using considerations of veridical representation, we can show that inattentive peripheral perception is less representationally precise than attentive foveal perception. However, there is empirical evidence to the contrary. The conclusion is that perceptual representation cannot ground what it is like to perceive.

_Puzzled?!_ seamlessly fuses two traditional approaches to the study of philosophy at the introductory level. It is thematic, examining fundamental issues in epistemology, metaphysics, philosophy of religion, and more. It is also historical, introducing major philosophical arguments that have arisen throughout the history of Western philosophy. But its real innovation lies elsewhere. Each of its twelve chapters begins with a traditional argument of a thoroughly puzzling kind: a valid philosophical argument with highly plausible premises but a surprising conclusion. The remainder (...) of the chapter shows how major innovations in the history of philosophy arise as logical responses to that argument. Written with a light touch, _Puzzled?!_ nevertheless offers a rigorous introduction to the ideas it explores and to the foundations of critical thinking itself. It will serve as effectively as a main or supplementary text in an introduction to critical thinking as it will in Philosophy 101. (shrink)

The Puzzle of the Hats is a betting arrangement which seems to show that a Dutch book can be made against a group of rational players with common priors who act in the common interest and have full trust in the other players’ rationality. But we show that appearances are misleading—no such Dutch book can be made. There are four morals. First, what can be learned from the puzzle is that there is a class of situations in which (...) credences and betting rates diverge. Second, there is an analogy between ways of dealing with situations of this kind and different policies for sequential choice. Third, there is an analogy with strategic voting, showing that the common interest is not always served by expressing how things seem to you in social decision-making. And fourth, our analysis of the Puzzle of the Hats casts light on a recent controversy about the Dutch book argument for the Sleeping Beauty. (shrink)

Pejoratives are the class of expressions that are meant to insult or disparage. They include swear words and slurs. These words allow speakers to convey emotional states beyond the truth-conditional contents that they are normally taken to encode. The puzzle arises because, although pejoratives seem to be a semantically unified class, some of their occurrences are best accounted for truth-conditionally, while others are best accounted for non-truth-conditionally. Where current, non-truth-conditional, views in the literature fail to provide a unified solution (...) for the puzzle, this paper motivates a novel, semantic, analysis of pejorative language. The significance of the proposed solution is not only linguistic in nature, but also philosophical, as it both provides a new argument for, and sheds further light on, the nature of semantic externalism.

The first page of Frege’s classic “Uber Sinn und Bedeutung” sets for more than a hundred years now the agenda for much of semantics and the philosophy of mind. It presents a purported puzzle whose solution is said to call upon the “entities” of semantics (meanings) and psychological explanation (Psychological states, beliefs, concepts). The paper separates three separate alleged puzzles that can be read into Frege’s data. It then argues that none are genuine puzzles. In turn, much of the (...) Frege-driven theoretical development, motivated as an inevitable “solution”, is thrown into doubt. (shrink)

In their 2010 book, Biology’s First Law, D. McShea and R. Brandon present a principle that they call ‘‘ZFEL,’’ the zero force evolutionary law. ZFEL says (roughly) that when there are no evolutionary forces acting on a population, the population’s complexity (i.e., how diverse its member organisms are) will increase. Here we develop criticisms of ZFEL and describe a different law of evolution; it says that diversity and complexity do not change when there are no evolutionary causes.
