I discuss the relation between egocentric spatial representation and the capacity for bodily activity, with specific reference to Merleau-Ponty.

In this paper I present a new theory of propositions, according to which propositions are abstract mathematical objects: well-formed formulas together with models. I distinguish the theory from a number of existing views and explain some of its advantages  chief amongst which are the following. On this view, propositions are unified and intrinsically truth-bearing. They are mind- and language-independent and they are governed by logic. The theory of propositions is ontologically innocent. It makes room for an appropriate interface with (...) formal semantics and it does not enforce an overly fine or overly coarse level of granularity. (shrink)

The view that dominates the literature on intentional attitudes holds that beliefs and desires both have propositional content. A commitment to what I call “content uniformity” underlies this view. According to content uniformity, beliefs and desires are but different psychological modes having a uniform kind of content. Prima facie, the modes don’t place any constraint on the kinds of content the attitude can have. I challenge this consensus by pointing out an asymmetry between belief contents and desire contents which shows (...) content uniformity to be mistaken. I do this by revisiting the arguments of Richard (Philosophical Studies, 39(1): 1–13, 1981), and show that arguments which purport to show the temporal specificity of belief contents yield the opposite results for desire contents. I defend this preliminary conclusion from various strategies to neutralize the asymmetry claim. My defense provides occasions to respond to objections by Brogaard (2012) and Recanati (2007) to the Richard argument, and to get clearer on the role of temporal adjuncts in desire ascriptions. Finally, I consider whether the construal of attitude content as centered propositions (as in Lewis Philosophical Review, 88(4): 513–543, 1979) can be invoked to vindicate content uniformity. My conclusion is that while the framework itself doesn’t vindicate content uniformity, it could, but only if it availed itself of a further, substantive thesis about desire, which itself is in need of defense.

There are two common reactions to Frege’s claim that some senses and thoughts are private. Privatists accept both private senses and thoughts, while intersubjectivists don’t accept either. Both sides agree on a pair of tacit assumptions: first, that private senses automatically give rise to private thoughts; and second, that private senses and thoughts are the most problematic entities to which Frege’s remarks on privacy give rise. The aim of this paper is to show that both assumptions are mistaken. This will (...) motivate a so far neglected, reconciliatory position between privatism and intersubjectivism according to which all thoughts are public while some senses are private. (shrink)

Libertarians about free will sometimes argue for their position on the grounds that our phenomenology of action is such that determinism would need to be false for it to be veridical. Many, however, have thought that it would be impossible for us to have an experience that is in contradiction with determinism, since this would require us to have perceptual experience of metaphysical facts. In this paper I show how the libertarian claim is possible. In particular, if experience depicts the (...) world such that there is more than one physically possible future, then determinism would need to be false for that experience to be veridical. I show that we have experiences, or perceptual episodes, of this kind on the basis of recent work in the study of perception. Theorists in this area have argued that we have vision-for-action, and that what we visually perceive are not just objects but also possibilities for action. If we experience that it is possible that we ϕ, then we also experience that it is possible that we not ϕ. Furthermore, we probably experience more than one possibility for action at any one moment. I argue that these are physical possibilities, and therefore that we experience the world such that there is more than one physically possible future. So the libertarian claim about the semantics of agential phenomenology is highly plausible, even if this does not entail libertarianism. (shrink)

That expressions should have their contents can seem paradigmatically contingent. But it can also seem a priori that expressions in one's own language should have their contents to the extent that instances of disquotation, such as "Socrates" refers to Socrates' and "cat" refers to cats', are trivially true. I attempt to reconcile these conflicting intuitions about meaningfulness by examining semantic and metasemantic details of linguistic reflexivity. I argue that instances of disquotation are contingent analytic in Kaplan's sense, and bring this (...) lesson to bear on semantic strategies for responding to skepticism, such as Putnam's Brains-in-a-Vat argument.

The facts aboutsuch, then, indicate not just thatsuch is a pro-adjective, but also that binding conditions apply broadly to pro-ADJs and pro-CNs, as well as to a wide range of pro-arguments. If this is true, the CN binding process accomplished by rules (40) and (41) might better be expressed in a system that uses a Cooper (1979) store mechanism. In fact, Stump (p. 144) notes that this could easily be done. Meanings of the type of∨ P n could be stored, (...) just as NP meanings are, until an appropriate binding CN phrase was encountered. Binding conditions would simply require that a∨ P n meaning not come out of storage until the derivation had emerged from its governing category. The behavior of the pro-adjectivesuch suggests that an expression of any category, if it is legitimately translatable as a variable, may be a fullfledged proform; many principles and mechanisms described to account for the widely studied pronouns in fact apply to nonargument categories.

According to an intuitive semantics for 'I,' 'here' and 'now,' 'I am not here now' should always be false when uttered. But occurrences of 'I am not here now' on an answering machine seem to be true (when the speaker is not home). A number of possible solutions are considered and rejected, and a novel solution offered introducing the notion of a 'deferred utterance,' which allows for non-mysterious sort of action at a distance.

The Sleeping Beauty puzzle has dramatized the divisive question of how de se beliefs should be integrated into formal theories of rational belief change. In this paper, I look ahead to a related question: how should de se beliefs be integrated into formal theories of rational choice? I argue that standard decision theoretic frameworks fail in special cases of de se uncertainty, like Sleeping Beauty. The nature of the failure reveals that sometimes rational choices are determined independently of one’s credences (...) in the kinds of ‘narrow’ de se propositions that Sleepy Beauty has set in relief. Consequently, in addition to pinpointing a failure of standard decision theoretic frameworks, this result casts doubt on a large class of strategies for determining principles for the rationally updating de se beliefs in cases like Sleeping Beauty, and also calls into question the importance of making such a determination at all.

One of the objections against the thesis of underdetermination of theories by observations is that it is unintelligible. Any two empirically equivalent theories — so the argument goes—are in principle intertranslatable, hence cannot count as rivals in any non-trivial sense. Against that objection, this paper shows that empirically equivalent theories may contain theoretical sentences that are not intertranslatable. Examples are drawn from a related discussion about incommensurability that shows that theoretical non-intertranslatability is possible.

In this paper I investigate which of the main conditions proposed in the moral responsibility literature are the ones that spell trouble for the idea that Artificial Intelligence Systems could ever be full-fledged responsible agents. After arguing that the standard construals of the control and epistemic conditions don’t impose any in-principle barrier to AISs being responsible agents, I identify the requirement that responsible agents must be aware of their own actions as the main locus of resistance to attribute that kind (...) of agency to AISs. This is because this type of awareness is thought to involve first-person or de se representations, which, in turn, are usually assumed to involve some form of consciousness. I clarify what this widespread assumption involves and conclude that the possibility of AISs’ moral responsibility hinges on what the correct theory of de se representations ultimately turns out to be.

It has been widely acknowledged that indexical thought poses a problem for traditional theories of mental content. However, recent work in philosophy has defied this received view and challenged its defenders not to rely on intuitions but rather to clearly articulate what the problem is supposed to be. For example, in “The Inessential Indexical”, Cappelen and Dever claim that there are no philosophically interesting or important roles played by essential indexical representations. This paper assesses the role of essential indexicality in (...) understanding the content of perception and argues that, if the perceptual experiences of different subjects can have the same phenomenology, and thus share a representational content (phenomenal content)—assumptions shared by a well-established research project, including a wide variety of theories—, then phenomenal content exhibit a particular kind of essential indexicality (perspectival). I also discuss how the argument is immune to Cappelen and Dever’s objections to the idea that the content of perceptual experiences is essentially indexical. (shrink)

Higher-order thought theories of consciousness attempt to explain what it takes for a mental state to be conscious, rather than unconscious, by means of a HOT that represents oneself as being in the state in question. Rosenthal Consciousness and the self: new essays, Cambridge University Press, Cambridge, 2011) stresses that the way we are aware of our own conscious states requires essentially indexical self-reference. The challenge for defenders of HOT theories is to show that there is a way to explain (...) the required reference-fixing mechanisms that is compatible with the theory. According to Rosenthal, the reference to oneself as such is grounded in the disposition to identify the individual the HOT refers to as the individual who has that HOT. I argue that this leads to a vicious infinite regress on the more than plausible assumption that our cognitive capacities are limited. This leaves such theories without a foundation, since self-reference is thought essential to consciousness. (shrink)

We seem to ascribe mental states and agency to groups. We say ‘Google knows such-and-such,’ or ‘Amazon intends to do such-and-such.’ This observation of ordinary parlance also found its way into philosophical accounts of social groups and collective intentionality. However, these discussions are usually quiet about how groups self-ascribe their own beliefs and intentions. Apple might explain to its shareholders that it intends to bring a new iPhone to the market next year. But how does Apple know what it intends? (...) How do groups get to know their own mental states? This is the question of collective self-knowledge. I argue that collective self-knowledge is a distinct phenomenon that deserves our attention. In particular I suggest: that we should be interested in collective self-knowledge, because our behaviour indicates that we already engage with collective self-knowledge in practice; that groups can collectively avow, which indicates that they have privileged and peculiar access to their own intentional states; and that collective self-knowledge is not reducible to intentional states of individuals and therefore is an independent explanandum.

Rational agents are supposed to maximize expected utility. But what are the options from which they choose? I outline some constraints on an adequate representation of an agent’s options. The options should, for example, contain no information of which the agent is unsure. But they should be sufficiently rich to distinguish all available acts from one another. These demands often come into conflict, so that there seems to be no adequate representation of the options at all. After reviewing existing proposals (...) for how to construe decision-theoretic options and finding them all wanting, I suggest that our model of rational agents should include a special domain of ‘virtual’ option propositions to serve as formal objects of deliberation and choice.

I defend a general rule for updating beliefs that takes into account both the impact of new evidence and changes in the subject’s location. The rule combines standard conditioning with a shifting operation that moves the center of each doxastic possibility forward to the next point where information arrives. I show that well-known arguments for conditioning lead to this combination when centered information is taken into account. I also discuss how my proposal relates to other recent proposals, what results it (...) delivers for puzzles like the Sleeping Beauty problem, and whether there are diachronic constraints on rational belief at all.

When an agent undergoes fission, how should the beliefs of the fission results relate to the pre-fission beliefs? This question is important for the Everett interpretation of quantum mechanics, but it is of independent philosophical interest. Among other things, fission scenarios demonstrate that ‘self-locating’ information can affect the probability of uncentred propositions even if an agent has no essentially self-locating uncertainty. I present a general update rule for centred beliefs that gives sensible verdicts in cases of fission, without relying on (...) controversial metaphysical or linguistic assumptions. The rule is supported by the same considerations that support standard conditioning in the traditional framework of uncentred propositions. (shrink)

Kaplan claims in Demonstratives that no operator may manipulate the context of evaluation of natural language indexicals. We show that this is not so. In fact, attitude reports always manipulate a context parameter (or, rather, a context variable). This is shown by (i) the existence of De Se readings of attitude reports in English (which Kaplan has no account for), and (ii) the existence of a variety of indexicals across languages whose point of evaluation can be shifted, but only in (...) attitude reports. We develop an alternative account within an extensional framework with overt quantification over times, worlds and contexts. Various typological facts are discussed, esp. the distinction between English, Amharic and Ewe pronouns, and that between English and Russian tenses. (shrink)

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of (...) an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self-locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality. (shrink)

The Centred View offers an account of the connection between imagination and possibility that combines the centred world framework with some allegedly appealing intuitions regarding our persistence over time. In particular, Dilip Ninan suggests that the Centred View has the theoretical advantage of respecting our intuitions about cases of personal identity in certain imaginative scenarios while also being compatible with physicalism. Unfortunately, the Centred View faces a series of serious objections and should ultimately be rejected.

Some use the need to explain communication, agreement, and disagreement to argue for two-dimensional conceptions of belief content. One prominent defender of an account of this sort is David Chalmers. Chalmers claims that beliefs have two kinds of content. The second dimension of belief content, which is tied to what beliefs pick out in the actual world, is supposed to help explain communication, agreement, and disagreement. I argue that it does not. Since the need to explain these phenomena is the (...) main stated motivation for the addition of the second dimension of belief content, my arguments also undermine the motivation for Chalmers’ two-dimensional account of belief content and theories like it.

Know-how and expressivism are usually regarded as disjoint topics, belonging to distant areas of philosophy. This paper argues that, despite obvious differences, the two debates have important similarities. In particular, semantic and conceptual tools developed by expressivists can be exported to the know-how debate. On the one hand, some of the expressivists' semantic resources can be used to deflect Stanley and Williamson's influential argument for factualism about know-how: the claim that knowing how to do something consists in knowing a fact. (...) On the other, expressivism provides the resources to formulate a nonfactualist account of know-how. On this account, know-how has a kind of nonpropositional content and plays the role of guiding performance of action, rather than recording information from the environment. (shrink)

The conventional wisdom regarding the aims and shortcomings of Kantian constructivism is mistaken. The aim of metaethical constructivism is not to provide a naturalistic account of the objectivity of normative facts by deriving substantive morality from a conception of agency so thin as to be uncontroversial (a task at which it is generally regarded to have failed). Its aim is to explain the “grip” that normative facts have on us—to avoid what I call the problem of normative alienation. So understood, (...) Kantian constructivism faces two problems: that determinate normative facts cannot be derived from agency and that its individualistic conception of agency cannot account for the sociality of morality. I propose and elaborate a social conception of agency that is better able to address the latter problem while still avoiding normative alienation, and evaluate two different strategies for responding to the former problem.

I critically examine the assumption that the theoretical structure that varies under theoretical symmetries is redundant and should be eliminated from a metaphysical picture of the universe, following a ‘symmetry to reality’ inference. I do so by analysing the status of coordinate change symmetries taking a pragmatic approach. I argue that coordinate systems function as indexical devices, and play an important pragmatic role for representing concrete physical systems. I examine the implications of considering this pragmatic role seriously, taking what I (...) call a perspectivist stance. My conclusion is that under a perspectivist stance, all symmetries (including local gauge symmetries) potentially have a direct empirical status: they point to dynamical aspects that are invariant under changes of operationalisation, and they constitute a guide not to reality, but to nomology and kinship.

The Epistemic Objection says that certain theories of time imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in the details which avoids this problem, using epistemic safety. The new version has two interesting upshots. First, while Ross Cameron alleges that the Epistemic (...) Objection applies to presentism as much as to theories like the growing block, the safety version does not overgeneralize this way. Second, the Epistemic Objection does generalize in a different, overlooked way. The safety objection is a serious problem for a widely held combination of views: “propositional temporalism” together with “metaphysical eternalism”. (shrink)

This paper investigates, formulates and proves an indexical barrier theorem, according to which sets of non-indexical sentences do not entail (except under specified special circumstances) indexical sentences. It surveys the usual difficulties for this kind of project, as well some that are specific to the case of indexicals, and adapts the strategy of Restall and Russell's "Barriers to Implication" to overcome these. At the end of the paper a reverse barrier theorem is also proved, according to which an indexical sentence (...) will not, except under specified circumstances, entail a non-indexical one. (shrink)

This paper proves a precisification of Hume’s Law—the thesis that one cannot get an ought from an is—as an instance of a more general theorem which establishes several other philosophically interesting, though less controversial, barriers to logical consequence.

In recent years there has been a heated debate on how to accommodate John Perry's observations about the essentiality of indexicality into our models of linguistic communication. This article is an attempt at providing a new perspective on this issue. I argue that we should jettison two elements taken for granted by the views I present, and criticize, here: no centring, uncentring, recentring and multicentring. These elements are: (1) taking the asserted content to be a part of the communication process (...) and (2) assumptions that the indexical belief of the speaker, when successfully communicated, must be acquired by the hearer as indexical, too. The theory of indexical communication that I propose here is laid out in the mental files framework and devoid of the two aforementioned elements. (shrink)

This paper explores certain facets of Christine Korsgaard’s paper, ‘Prospects for a Naturalistic Explanation of the Good’. Korsgaard’s account requires that an animal be able to experience ‘herself trying to get or avoid something’. The claim that animals possess such self-awareness is regarded by many as problematic and, if this is correct, it would jeopardize Korsgaard’s account. This paper argues that animals can, in fact, be aware of themselves in the way required by Korsgaard’s account.

The major goal of René Descartes’s rich and penetrating recent book, Meditations on First Philosophy, is to develop a methodology for the discovery of the truth, more specifically, a methodology that accommodates the dictates of a mathematical physics for our view of physical reality. Such a methodology must accordingly deal with and seek to defuse the apparent conflict between a mathematical physics and our commonsense picture of things, a conflict that continues to pose difficult challenges. Though much in the book (...) is devoted to an account of the mind, that focus results from the broader goal of finding a methodology for discovery that will deliver an overall picture of reality consonant with a mathematical physics. Much that Descartes says in this book may strike many readers as extravagant and implausible, and perhaps hardly worth serious consideration. But there is a line of argument one can extract that is challenging and often compelling, even if not in the end wholly convincin .. (shrink)

The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we call (...) reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

This critical notice provides an overview of Harry Frankfurt’s On Inequality and assesses whether Frankfurt is right to argue that equality is merely formal and empty. I counter-argue that egalitarianism, properly tweaked and circumscribed, can be defended against Frankfurt’s repudiation. After surveying the main arguments in Frankfurt’s book, I argue that whatever plausibility the ‘doctrine of sufficiency’ defended by Frankfurt may have, it does not strike a fatal blow against egalitarianism. There is nothing in egalitarianism that forbids acceptance of the (...) moral platitude expressed in sufficientarianism's positive thesis,. Nor is there anything in egalitarianism as such that makes it impossible to recognize the banal truth that there are many important things besides equality, and that many dimensions of human affairs are improperly appraised from a relational or comparative point of view.

Each of us enjoys a special awareness of (some) of her mental states. The adverbial model of first-person awareness claims that to be aware of a mental state is for it to be conscious, where ‘conscious’ describes the kind of state it is, rather than denoting a form of awareness directed at it. Here, I present an argument for construing first-person awareness of intentions adverbially, by showing that this model can meet a serious challenge posed by the simulation hypothesis, which (...) draws on data about schizophrenia.

It has been claimed that we need singular self-knowledge to function properly as rational agents. I argue that this is not strictly true: agents in certain relations could dispense with singular self-knowledge and instead rely on plural self-knowledge. In defending the possibility of this kind of ‘selfless agent’, I thereby defend the possibility of a certain kind of ‘seamless’ collective agency; agency in a group of agents who have no singular self-knowledge, who do not know which member of the group (...) they are. I discuss four specific functions for which singular self-knowledge has been thought indispensable: distinguishing intentional from unintentional actions, connecting non-indexical knowledge with action, reflecting on our own reasoning, and identifying which ultimate practical reasons we have. I argue in each case that by establishing certain relations between agents – relations I label ‘motor vulnerability’, ‘cognitive vulnerability’, ‘evidential unity’ and ‘moral unity’ – we would allow those agents to do everything a rational agent needs to do while relying only on plural, rather than singular, self-knowledge. Finally, I consider the objection that any agents who met the conditions I lay out for selfless agency would thereby cease to qualify as distinct agents, merging into a single agent without agential parts. Against this objection, I argue that we should recognise the possibility of simultaneous agency in whole and parts, and not regard either as disqualifying the other. (shrink)

Perdurantists hold that we persons—just like other ordinary objects—persist by perduring, by having temporal parts, or stages, located over time. Perdurantists also standardly endorse the B-theory of time. And, in light of this endorsement, they typically characterize our tensed beliefs as self-ascriptions of properties, made not by us but by our stages. For instance, for me to believe that Angela Merkel is currently the chancellor of Germany is for my now-located stage to self-ascribe the property of being simultaneous with Merkel’s (...) chancellorship. The problem with this way of understanding tensed belief is that it undermines—if not outright contradicts—the perdurantist’s best options for resisting the Too Many Thinkers objection. In what follows, I show why this is. I then consider what I take to be the perdurantist’s most promising alternative account of tensed belief. I argue that this alternative either leaves perdurantists no better off with respect to the Too Many Thinkers objection or, instead, leaves them vulnerable to another objection, one that they would otherwise have no problem resisting.
