Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit—how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express (...) attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes. (shrink)

The conceivability argument against materialism, originally raised by Saul Kripke and then reformulated, among others, by David Chalmers holds that we can conceive of the distinctness of a phenomenal state and its neural realiser, or, in Chalmers’ variation of the argument, a zombie world. Here I argue that both phenomenal and natural kind terms are ambiguous between two senses, phenomenal and natural, and that the conceivability argument goes through only on one reading of a term. Thus, the antimaterialist has to (...) provide some reasons independent of anti-materialism itself to favour that reading of a term that supports his or her argument. Given that there are no such independent reasons, I conclude that we should put more weight on empirical considerations than on a priori discussion in resolving the question concerning the identity between a phenomenal state and its neural realiser.

Can there be relational universals? If so, how can they be exemplified? A monadic universal is by definition capable of having a scattered spatiotemporal localization of its different exemplifications, but the problem of relational universals is that one single exemplification seems to have to be scattered in the many places where the relata are. The paper argues that it is possible to bite this bullet, and to accept a hitherto un-discussed kind of exemplification relation called ‘scattered exemplification’. It has no (...) immediate symbolic counterpart in any Indo-European natural language or in any so far constructed logical language. In order to remedy this, a notion called ‘many-place copula’ is introduced, too. (shrink)

If the logic of belief changes is extended to cover belief states which contain both factual and normative beliefs, it is easily shown that a change of a factual belief (an 'Is') in a mixed belief state can imply a change of a normative belief (an 'Ought') in the same state. With regard to Hume's so-called 'Is-Ought problem', this means that one has to distinguish its statics from its dynamics. When this is done, it becomes clear that changes of factual (...) beliefs can, for rational reasons, have far-reaching normative consequences. Similarly, a change of a factual belief can imply a change of a value belief. (shrink)

I argue in defense of Aristotle's position that contemplation is the proper use of at least some of one's leisure and that, consequently, leisure education must consist in teaching the inclination and capacity for contemplation. However, my position is somewhat more flexible than Aristotle's, in that I allow that there are other activities worthy of some leisure. My argument examines Aristotle's own comments on the importance of theoria as well as commentaries by Ackrill, Nagel, Broadie, Green and Telfer. In the (...) conclusion I argue that there are good reasons to think that studying Philosophy is one of the best strategies for leisure education. (shrink)

Global metaphysical antirealism (or “antirealism”) is often thought to entail that the identity of each and every concrete entity in our world ultimately depends on us—on our adoption of certain social and linguistic conventions, for instance, or on our use of certain conceptual schemes. Drawing on the middle‐period works of Maurice Merleau‐Ponty, I contend that metaphysical antirealism entails nothing of the sort. For Merleau‐Ponty, I argue, entities do not ultimately owe their identities to us, even though—as he puts it—their “articulations (...) are the very ones of our existence.” Once this is recognised, I maintain, certain interpretations of phenomenology are revealed to be caricatures and certain general objections to antirealism lose their force.

A traditional explanation that dates back to Aristotle is that we access color in one perceptual modality only, whereas shape we perceive via two different modalities: visual and tactile. Two independent modalities make possible a verification of our percepts which is not possible for qualities accessed in one modality only.

Which properties can we visually experience? Some authors hold that we can experience only low-level properties such as color, illumination, shape, spatial location, and motion. Others believe that we can also experience high-level properties, such as being a dog or being a pine tree. On the basis of her method of phenomenal contrast, Susanna Siegel has recently defended the latter view. One of her central claims is that we can best account for certain phenomenal contrasts if we assume that we (...) can visually experience natural kind properties. In this paper, I argue that certain kinds of low-level properties, namely shape-gestalt properties, can explain these phenomenal contrasts just as well as high-level properties. If successful, this is a modest, but nevertheless significant result. Even though it does not prove the falsity of Siegel’s proposal, it nevertheless secures the existence of a plausible alternative.

The verb ‘to know’ can be used both in ascriptions of propositional knowledge and ascriptions of knowledge of acquaintance. In the formal epistemology literature, the former use of ‘know’ has attracted considerable attention, while the latter is typically regarded as derivative. This attitude may be unsatisfactory for those philosophers who, like Russell, are not willing to think of knowledge of acquaintance as a subsidiary or dependent kind of knowledge. In this paper we outline a logic of knowledge of acquaintance in (...) which ascriptions like ‘Mary knows Smith’ are regarded as formally interesting in their own right, remaining neutral on their relation to ascriptions of propositional knowledge. The resulting logical framework, which is based on Hintikka’s modal approach to epistemic logic, provides a fresh perspective on various issues and notions at play in the philosophical debate on acquaintance.

I argue that mental descriptivism cannot be reasonably thought superior to rival theories on the grounds that it can (while they cannot) provide an elegant account of reference failure. Descriptivism about the particular-directed intentionality of our mental states fails when applied to desires. Consider, for an example, the desire that Satan not tempt me. On the descriptivist account, it looks like my desire would be fulfilled in conditions in which there exists exactly one thing satisfying some description only Satan satisfies (...) (call it the Satanic Description). However, against this analysis, it is clearly compatible with desiring that Satan not tempt me that I also desire that there exist nothing satisfying the Satanic Description. The descriptivist has room for maneuver here, but the cost of accommodating this phenomenon is that the descriptivist shall no longer be able to use her theory to ameliorate the possibility of reference failure.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

What is exemplification? A proposition that attributes a property to an object is true if the object exemplifies the property. But according to the correspondence theory, a proposition is true if the corresponding fact exists. So if the correspondence theory is correct, an exemplification of a temporal property by an object is simply the concrete circumstance of the object’s having the property. But since not all properties are temporal, not all exemplifications are circumstances, and we need to recognise timeless as (...) well as temporal facts. This distinction allows us to solve the problem of converse relations, and to give an account of the logically complex facts which deduction allows us to know. (shrink)

The notion of the absolute time-constituting flow plays a central role in Edmund Husserl’s analysis of our consciousness of time. I offer a novel reading of Husserl’s remarks on the absolute flow, on which Husserl can be seen to be grappling with two key intuitions that are still at the centre of current debates about temporal experience. One of them is encapsulated by what is sometimes referred to as an intentionalist (as opposed to an extensionalist) approach to temporal experience. The (...) other centres on the thought that temporal experience itself necessarily unfolds over time. I show how some of Husserl’s more enigmatic-sounding remarks about the absolute flow become intelligible if they are read as attempts to accommodate both these intuitions at the same time. However, I also question whether Husserl ultimately provides good reasons for preferring his intentionalist approach to a rival extensionalist one. (shrink)

Philosophers frequently comment on the intimate connection there is between something’s being present in perceptual experience and that thing’s being, or at least appearing to be, temporally present. Yet, there is relatively little existing work that goes beyond asserting such a connection and instead examines its specific nature. In this paper, I suggest that we can make progress on the latter by looking at two more specific debates that have hitherto been conducted largely isolation from each other: one about the (...) nature of conscious experience and one about the nature of time itself. The first concerns the extent to which the temporal properties of experience form an exception to the transparency of experience, meaning that introspection can provide support for one particular view of how experience itself is structured temporally; the second concerns the question as to whether there is something about experience that gives us grounds for thinking that the present is somehow metaphysically special. As I argue, the idea of a connection between experiential presence and temporal presence plays a key background role in each of these debates. Yet it can also, in each of them, be seen to draw one side towards making claims that are supposed to express an important truth but are at the same time, on the face of it, self-contradictory. In each case, resolving what it actually is that these claims are trying to get at turns on recognizing a distinctive feature of perceptual experience, which I refer to as its lack of temporal viewpointedness. Recognising this feature also helps in making sense of what the issues at stake actually are in the intuition of an intimate connection between experiential presence and temporal presence. (shrink)

I resolve an apparently unresolved dispute about how probable uniform experience makes an extrapolation from it, and draw some general lessons about such enumerative induction. Uniform experience does not necessarily confer a high probability on an extrapolation of or generalization from that experience. Rational extrapolation or generalization typically involves a lot of specific background information, though not necessarily a general assumption that nature is uniform or that the future will resemble the past. And new evidence which is highly likely on (...) one hypothesis but highly unlikely on any of its competitors does not necessarily make the former hypothesis highly probable. (shrink)

When one is intentionally doing something, one represents that thing as a goal to be accomplished. One represents it practically. How should we characterize this practical representation further? In this paper, I argue that when one is intentionally doing something, one's representation of it as a goal to be accomplished must also be knowledge that one is intentionally doing that thing. And I argue that this knowledge must itself be one's intentionally doing that thing. I aim to show, then, that (...) insofar as representing practically just is knowing practically, it is equally acting intentionally. (shrink)

According to structuralism, all natural properties are individuated by their roles in causal/nomological structures. According to quidditism, at least some natural properties are individuated in some other way. Because these theses deal with the identities of natural properties, this distinction cuts to the core of a serious metaphysical dispute: Are the intrinsic natures of all natural properties essentially causal/nomological in character? I'll argue that the answer is ‘no’, or at least that this answer is more plausible than many critics of (...) quidditism have recognized. In section 1, I distinguish between two versions of quidditism. Bare quidditism holds that worlds with distinct properties and isomorphic structures must be qualitatively identical in the following sense: inhabiting one world would be indistinguishable from inhabiting the other. In contrast, qualitative quidditism allows such worlds to have qualitative differences. In section 2, I discuss an epistemological position that allows us to bett... (shrink)

In recent discussions of the problem of truth, Austin's views have been largely overlooked. This is unfortunate, since many of his criticisms aimed at Strawson's redundancy theory carry over to more recent incarnations of deflationism. And unlike contemporary versions of the correspondence theory of truth, Austin's manages properly to situate truth in its conceptual neighbourhood wherein it belongs to “a whole dimension of different appraisals which have something or other to do with the relation between what we say and the (...) facts.” A proper analysis of truth cannot be given apart from a broader study of speech acts.

This paper argues that the normative character of our unreflective situated behaviour is not factual. We highlight a problematic assumption shared by the two most influential trends in contemporary philosophy of cognitive science, reductionism and enactivism. Our intentional, normative explanations are referential, descriptive or factual. Underneath this assumption lies the idea that only facts can make true or false our attributions of cognitive, mental and agential abilities. We will argue against this view by describing the main features and problems of (...) reductionism and enactivism and then we will offer two arguments against this shared factualist assumption: (1) normative vocabulary is ineliminable if we want a complete explanation of our situated practices; and (2) the factualist assumption is a species of the is-ought fallacy. Finally, we will claim that a folk psychological explanation of our normative practices is fully compatible with ontological naturalism when such descriptivist or factualist assumption is rejected.

We are very grateful to our critics for their kind words and thoughtful engagementwith The Reference Book (hereafter TRB), and also to the editors of Mind & Language for the opportunity to respond. We’ll start our reply by sketching the book’s positive thesis about specific noun phrases and names. In §2 we’ll relate the traditional semantic category we call ‘reference’ to semantic taxonomies given in terms of mechanisms of denotation. In §3, we’ll turn to acquaintance constraints on reference and singular (...) thought. And in §4, we’ll briefly address McGilvray’s and Devitt’s general doubts about the project of truth-conditional semantics to which our book contributes. (shrink)

I defend external world realism. I assume that the principle of inference to the best explanation is justified: roughly, a hypothesis that provides a better explanation of the total evidence is more probable than one that does not. I argue that the existence of a world of spatial objects provides a systematic explanation of the spatial contents of visual experience, and that it provides a better explanation than traditional skeptical hypotheses. This paper thus pursues the explanationist strategy of Laurence BonJour (...) and Jonathan Vogel. It is an improved, more compelling defense, for at least two reasons. First, the attention to spatial properties, and in particular to what I call perspectival projections, makes the explanatory power of the realist hypothesis much more vivid and concrete. Second, the argument preserves and elucidates much that seems correct in the explanationist arguments others have offered while avoiding significant problems and shortcomings. (shrink)

In this article, I defend a version of ontological pluralism, specifically with an eye toward laying metaphysical groundwork for an account of divine naming inspired by Avicenna. I try to show (1) that Avicenna’s pluralism is well-motivated as a metaphysical thesis and (2) that it offers substantive philosophical support for a correlatively pluralist approach to divine naming. My argument proceeds by identifying two influential objections to ontological pluralism, and then offering replies to these objections with the help of Avicenna. The (...) first objection pertains to pluralism as a position in general metaphysics, whereas the second pertains to pluralism as a position in theological epistemology or divine naming. To the extent that these replies are successful, I argue that Avicennian pluralism is compelling on both counts as a philosophical position. (shrink)

Because our only access to color qualities is through their appearance, Byrne & Hilbert's insistence on a strict distinction between apparent colors and real colors leaves them without a principled way of determining when, if ever, we see colors as they really are.

What is the primary intellectual aim of philosophy? The standard view is that philosophy aims to provide true answers to philosophical questions. But if our aim is to settle controversy by answering such questions, our discipline is an embarrassing failure. Moreover, taking philosophy to aim at providing true answers to these questions leads to a variety of puzzles: How do we account for philosophical expertise? How is philosophical progress possible? Why do job search committees not care about the truth or (...) falsity of a candidate’s philosophical views? We argue that philosophy does not aim at discovering true answers to philosophical questions. Instead, its primary intellectual aim is understanding. We argue that many familiar aspects of philosophy become intelligible once we accept this hypothesis. (shrink)

Peter van Inwagen proposes a criterion of philosophical success. He takes it to support an extremely pessimistic view about philosophy. He thinks that all philosophical arguments for substantive conclusions fail, including the argument from evil. I’m more optimistic on both counts. I’ll identify problems with van Inwagen’s criterion and propose an alternative. I’ll then explore the differing implications of our criteria. On my view, philosophical arguments can succeed and the argument from evil isn’t obviously a failure.

We argue that Recanati burdens his otherwise salutary “Mental File” account of singular thought with an “Actualist” assumption that he has inherited from the discussion of singular thought since at least Evans, according to which singular thoughts can only be about actual objects: apparent singular thoughts involving “empty” terms lack truth-valuable content. This assumption flies in the face of manifestly singular thoughts involving not only fictional and mistakenly postulated entities, such as Zeus and the planet Vulcan, but also “perceptual inexistents,” (...) e.g., Kanizsa figures, rainbows, words and phonemes, as well as hosts of at best metaphysically problematic “objects,” such as properties, numbers, ceremonies, contracts, symphonies, “the sky,” “the rain.” Indeed, reflection on what seems to be the boundless diversity of “things” about which we seem to be able to have singular thoughts strongly suggests that there may be no general metaphysics of objects, much less “acquaintance” and “epistemically rewarding” relations that would distinguish singular from non-singular thought. We recommend that Recanati and other mental file theorists confine the theory to a metaphysically neutral account of singular thought as specific kind of internally “focused” computational state, and not seek any general account of the relation of thought to reality.

This paper defends the epistemological doctrine of fallibilism from recent objections. In “The Myth of Knowledge” Laurence BonJour argues that we should reject fallibilism for two main reasons: first, there is no adequate way to specify what level of justification is required for fallible knowledge; second, we cannot explain why any level of justification that is less than fully conclusive should have the significance that makes knowledge valuable. I will reply to these challenges in a way that allows me to (...) make progress on a number of important issues in contemporary epistemology: epistemic value, the functional roles of knowledge attributions, experimental epistemology, skepticism, the Gettier problem, and the lottery paradox. My argument is motivated by appealing to various insights derived from the method of ‘practical explication’, particularly the idea that a central purpose of the concept of knowledge is to flag reliable informants. My conclusion is that various practical and theoretical considerations derived from the method of practical explication support the fallibilist conception of knowledge. (shrink)

The problem of the source of necessity is the problem of explaining what makes necessary truths necessarily true. Simon Blackburn has presented a dilemma intended to show that any reductive, realist account of the source of necessity is bound to fail. Although Blackburn's dilemma faces serious problems, reflection on the form of explanations of necessities reveals that a revised dilemma succeeds in defeating any reductive account of the source of necessity. The lesson is that necessity is metaphysically primitive and irreducible.

The present paper offers an analogical support for the use of rational intuition, namely, if we regard sense perception as a mental faculty that (in general) delivers justified beliefs, then we should treat intuition in the same manner. I will argue that both the cognitive marks of intuition and the role it traditionally plays in epistemology are strongly analogous to that of perception, and barring specific arguments to the contrary, we should treat rational intuition as a source of prima facie (...) justified beliefs. There are two main arguments against the intuition-perception analogy that I will consider and find lacking. First is that while we do use perceptions as evidence to believe certain propositions, in fact no one ever does use intuition evidentially. The second argument, stemming from experimental philosophy, grants that philosophers do use intuitions evidentially, but this practice is fatally unlike that of perception, in that perception yields warranted beliefs and intuition does not.

How are philosophical questions about what kinds of things there are to be understood and how are they to be answered? This paper defends broadly Fregean answers to these questions. Ontological categories—such as object , property , and relation —are explained in terms of a prior logical categorization of expressions, as singular terms, predicates of varying degree and level, etc. Questions about what kinds of object, property, etc., there are are, on this approach, reduce to questions about truth and logical (...) form: for example, the question whether there are numbers is the question whether there are true atomic statements in which expressions function as singular terms which, if they have reference at all, stand for numbers, and the question whether there are properties of a given type is a question about whether there are meaningful predicates of an appropriate degree and level. This approach is defended against the objection that it must be wrong because makes what there depend on us or our language. Some problems confronting the Fregean approach—including Frege’s notorious paradox of the concept horse—are addressed. It is argued that the approach results in a modest and sober deflationary understanding of ontological commitments. (shrink)

Throughout its history philosophy has been thought to be a member of a community of intellectual disciplines united by their common pursuit of knowledge. It has sometimes been thought to be the queen of the sciences, at other times merely their under-labourer. But irrespective of its social status, it was held to be a participant in the quest for knowledge – a cognitive discipline.

A foundationalist account of our empirical thinking divides propositions we accept into two classes, basic and derivative, and sees the warrant of derivative propositions as accruing to them through their derivation from basic propositions. Such an account needs to answer two questions: which propositions are basic, and whence do basic propositions acquire their warrant? A natural and ancient answer to these questions is that basic propositions are observational and that these propositions gain their warrant from perceptions. I critically examine this (...) view and also a variant view offered by Wilfrid Sellars. I put forward an alternative conception, dialectical foundationalism, that sees the distinction between the basic and the derivative as issuing from a distinction between two kinds of reasoning, derivational and dialectical. This type of foundationalism provides a more accurate account of our empirical thinking, I argue, than its traditional and Sellarsian counterparts. (shrink)

ABSTRACTEmpathy is an underexplored dimension of the moral life. What if we could enter a machine that let us feel another person's subjective life? What kind of effect would that have on our moral awareness? Since this cannot be done, I suggest several ways to increase empathy and deepen our moral sensitivities.

Externalist representationalism is touted as a superior rival to naïve realism, and yet a careful analysis of the externalist representationalist's analysis of our ordinary perceptual experiences shows the view to be far closer to naïve realism than we might have expected. One of the central advertised benefits of representationalist views in general is that they are compatible with the idea that ordinary, illusory and hallucinatory perceptual experiences are of the same fundamental kind. Naïve realists are forced to deny the ‘common (...) fundamental kind claim’ and adopt disjunctivism. However, I argue that externalist representationalism is also a version of disjunctivism. Consequently, one of the main rivals to naïve realism turns out not to be a rival at all. (shrink)

The view that physical objects do not, in fact, possess colour properties is certainly the dominant position amongst scientists working on colour vision. It is also a reasonably popular view amongst philosophers. However, the recent philosophical debate about the metaphysical status of colour properties seems to have taken a more realist turn. In this article, I review the main philosophical views – eliminativism, physicalism, dispositionalism and primitivism – and describe the problems they face. I also examine how these views have (...) been classified and suggest that there may be less disparity between some of these positions than previously thought. (shrink)

Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

In Sein und Zeit Heidegger makes several claims about the nature of ‘assertion’ [Aussage]. These claims are of particular philosophical interest: they illustrate, for example, important points of contact and divergence between Heidegger's work and philosophical movements including Kantianism, the early Analytic tradition and contemporary pragmatism. This article provides a new assessment of one of these claims: that assertion is connected to a ‘present-at-hand’ ontology. I also indicate how my analysis sets the stage for a new reading of Heidegger's further (...) claim that assertion is an explanatorily derivative phenomenon. I begin with a loose overview of Heidegger's position and then develop a sharper formulation of the key premises. I go on to argue that existing treatments of the supposed link between assertion and the ‘present-at-hand’ are unsatisfactory, and advance a new, ‘methodological’, interpretation of that link. Finally, I sketch the implications of my interpretation for the further claim that assertion is explanatorily derivative. (shrink)

There is no consensus about appropriate philosophical method that can be relied on to settle philosophical questions and instead of established findings, there are multiple conflicting arguments and positions, and widespread disagreement and debate. Given this feature of philosophy, it might seem that philosophy has proven to be a worthless endeavour, with no possibility of philosophical progress. The challenge then is to develop a conception of philosophy that reconciles the lack of general or lasting agreement with the possibility of philosophical (...) progress. I present such a conception in this paper. I argue that the aim of philosophy is to resolve philosophical problems, which is different from establishing settled and final answers or positions. Philosophical problems involve inadequate or incongruous conceptions that cannot be settled once and for all but can be resolved by transforming our conceptions so they are now congruous and adequate. There is philosophical progress every time a warranted, defensible position is developed that resolves a philosophical problem, even if there are competing resolutions and further problems to resolve, as there always are in philosophy.

Introspective knowledge by acquaintance is knowledge we have by being directly aware of our phenomenally conscious states. In this paper, I argue that introspective knowledge by acquaintance is a sui generis kind of knowledge: it is irreducible to any sort of propositional knowledge and is wholly constituted by a relationship of introspective acquaintance. My main argument is that this is the best explanation of some epistemic facts about phenomenal consciousness and introspection. In particular, it best explains the epistemic asymmetry between (...) a subject who has never had a certain phenomenal state and one who has. I also consider two theoretical objections to my claim: an objection from disunity and an objection from mysteriousness. I show that these objections can be answered and that introspective knowledge by acquaintance being sui generis remains a live option on the table. (shrink)
