According to a prominent strand of thought in analytic philosophy of mind, certain judgments of the form “a is F” are such that, although one can be mistaken about what property it is that a has, one cannot be mistaken that it is a that has the relevant property. Judgments of this kind are said to be immune to error through misidentification (IEM). This article has two main aims. On the one hand, it responds to a need for a systematization (...) of the debate about immunity to error through misidentification, which consists of multiple contributions in epistemology, philosophy of language, philosophy of mind, and metaphysics that have accumulated throughout the last 80 years – since the publication of Ludwig Wittgenstein’s Blue Book – and which no one – to the best of our knowledge – has drawn together in an exhaustive and accessible way. On the other hand, the article will take a stand on matters concerning the nature, scope, explanation, and significance of immunity to error through misidentification. (shrink)

The view that first-person (de se) mental content is essential to the explanation of action in general is a strong essential indexicality thesis. A weaker essential indexicality claim is that de se mental content is an essential ingredient of intentional action. An argument by Bermúdez for the former thesis and an argument from Babb in support of the latter are discussed in Section 2, and for reasons presented there it seems that both arguments are unsound and the conclusions are false (...) as well. However, the discussion of their arguments helps us identify a certain class of intentional action, and an apparently very large class, the members of which are guaranteed to have de se origin. This class of intentional action is identified in Sections 3 and 4 and it is shown that necessarily, any member of this class has its origin in indexical, specifically, de se mental content.

This paper has two aims. The first concerns the question of whether there is any essential involvement of perspectival thought in intentional agency. I defend the view that the answer is ‘no’ for one kind of perspectival thought, and ‘yes’ for a different kind. Agency does not depend on de se thought, but it does depend on de nunc thought. The second aim of the paper is to defend a claim about the significance of this de se–de nunc contrast as (...) a case study. I argue that the contrast is best explained by a picture on which different kinds of perspectival thought are seen as islands. On this picture, an account of the conceptual role of one kind of perspectival thought won’t settle much about any other kind of perspectival thought. The picture is proposed as a replacement for the standard picture, on which perspectival thought is seen as a natural cognitive kind. (shrink)

According to First-Person Realism, one's own first-person perspective on the world is metaphysically privileged in some way. After clarifying First-Person Realism by reference to parallel debates in the metaphysics of modality and time, I survey eight different arguments in favor of First-Person Realism.

This essay offers a proposal for how to understand the idea that there is a special connection between de se attitudes and the explanation of action.

ABSTRACT We show that some PRO-sentences appear to receive de re interpretations when they occur in suitable discourse contexts or linguistic environments. This finding is surprising given the received view that such sentences are unambiguously de se [Morgan. 1970. “On the Criterion of Identity for Noun Phrase Deletion.” Papers from the Sixth Regional Meeting of the Chicago Linguistics Society, Chicago, IL, 380–389; Chierchia. 1990. “Anaphora and Attitudes de se.” In Semantics and Contextual Expression, edited by R. Bartsch, J. van Benthem, (...) and P. van Emde Boas, 1–32. Dordrecht: Foris]. We argue that these apparent de re readings are not genuine readings assigned by the grammar, but rather arise via a pragmatic process that results in what we call ‘excluded entailments’. The interpretation of PRO-sentences thus shows a certain amount of pragmatic latitude that is reminiscent of other cases of non-literal language, such as examples of ‘pragmatic slack’ first discussed in Lasersohn [1999. “Pragmatic Halos.” Language 75: 522–551]. However, we show that there are crucial differences between the puzzling data at hand and more familiar cases of pragmatic slack, and argue that they constitute a different class of non-literal meaning that has received less attention in the literature. This class of meanings is akin to that introduced by the modifier ‘in effect’. Our view has consequences for semantic methodology, understanding the limits of non-literal language use and interpretation, and the division of labour between semantics and pragmatics in the analysis of attitude reports.

Bodily sensations are mental states typically suitable to be reported in judgments in which a first-person indexical is used to qualify the felt body. In other words, subjects typically have a sense of bodily ownership for the body that they feel in bodily sensations. This paper puts forward, firstly, three desiderata that theories on the sense of bodily ownership should meet. Secondly, it assesses two views that account for the sense of bodily ownership in terms of the spatial content of (...) bodily sensations, appealing to a notion of a sense of boundedness, and argues that they do not meet the goals defined.

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.

I propose and defend a novel view called “de se consequentialism,” which is noteworthy for two reasons. First, it demonstrates—contra Doug Portmore, Mark Schroeder, Campbell Brown, and Michael Smith, among others—that agent-neutral consequentialism is consistent with agent-centered constraints. Second, it clarifies the nature of agent-centered constraints, thereby meriting attention from even dedicated nonconsequentialists. Scrutiny reveals that moral theories in general, whether consequentialist or not, incorporate constraints by assessing states in a first-personal guise. Consequently, de se consequentialism enacts constraints through the (...) very same feature that nonconsequentialist theories do. (shrink)

This paper takes up a neglected problem for metaethical noncognitivism: the characterization of the acceptance states for agent-centered normative theories like Rational Egoism. If Egoism is a coherent view, the non-cognitivist needs a coherent acceptance state for it. This can be provided, as Dreier and Gibbard have shown. But those accounts fail when generalized, assigning the same acceptance state to normative theories that are clearly distinct, or assigning no acceptance state to theories that look to be intelligible. The paper makes (...) the case for this and then asks: What should we conclude if the problem cannot be solved? We might conclude that since Egoism is clearly a coherent view, the argument amounts to a refutation of noncognitivism. But we suggest another possibility. There is, on reflection, something incoherent, or at least odd, in standard formulations of Egoism; noncognitivism predicts this and so provides an intriguing explanation for this fact. (shrink)

Is the fact that our universe contains fine-tuned life evidence that we live in a multiverse? Ian Hacking and Roger White influentially argue that it is not. We approach this question through a systematic framework for self-locating epistemology. As it turns out, leading approaches to self-locating evidence agree that the fact that our own universe contains fine-tuned life indeed confirms the existence of a multiverse. This convergence is no accident: we present two theorems showing that, in this setting, any updating (...) rule that satisfies a few reasonable conditions will have the same feature. The conclusion that fine-tuned life provides evidence for a multiverse is hard to escape. (shrink)

We draw attention to a series of implicit assumptions that have structured the debate about Frege’s Puzzle. Once these assumptions are made explicit, we rely on them to show that if one focuses exclusively on the issues raised by Frege cases, then one obtains a powerful consideration against a fine-grained conception of propositional-attitude content. In light of this consideration, a form of Russellianism about content becomes viable.

I examine what the mathematical theory of random structures can teach us about the probability of Plenitude, a thesis closely related to David Lewis's modal realism. Given some natural assumptions, Plenitude is reasonably probable a priori, but in principle it can be (and plausibly it has been) empirically disconfirmed—not by any general qualitative evidence, but rather by our de re evidence.

The Sleeping Beauty problem has attracted considerable attention in the literature as a paradigmatic example of how self-locating uncertainty creates problems for the Bayesian principles of Conditionalization and Reflection. Furthermore, it is also thought to raise serious issues for diachronic Dutch Book arguments. I show that, contrary to what is commonly accepted, it is possible to represent the Sleeping Beauty problem within a standard Bayesian framework. Once the problem is correctly represented, the ‘thirder’ solution satisfies standard rationality principles, vindicating why (...) it is not vulnerable to diachronic Dutch Book arguments. Moreover, the diachronic Dutch Books against the ‘halfer’ solutions fail to undermine the standard arguments for Conditionalization. The main upshot that emerges from my discussion is that the disagreement between different solutions does not challenge the applicability of Bayesian reasoning to centered settings, nor the commitment to Conditionalization, but is instead an instance of the familiar problem of choosing the priors.

De se attitudes seem to play a special role in action and cognition. This raises a challenge to the traditional way in which mental attitudes have been understood. In this chapter, we review the case for thinking that de se attitudes require special theoretical treatment and discuss various ways in which the traditional theory can be modified to accommodate de se attitudes.

My aim in this essay is to look back on and critically examine Tomis Kapitan’s (1949–2016) views of indexical language and indexical thought. Despite the novelty and insightfulness of Kapitan’s writings on these topics, his work has largely gone ignored. I believe this to be a tragic oversight, especially given the renewed interest in whether any of our thoughts might be essentially indexical. To be sure, there may be a reason for this oversight. In particular, Kapitan’s views are complex and (...) his writing often dense. So my hope is to do justice to his work on indexicality not only by making it more accessible but also by examining it in such a way as to demonstrate its strength and plausibility. (shrink)

David Lewis argues that believing something is self‐ascribing a property rather than holding true a proposition. But what is self‐ascription? Is it some new mysterious primitive? Is Lewis saying that every belief you have is about you? Several recent authors have suggested that, in the light of these questions, Lewis's theory should be rejected, despite its enormous influence. But this neglects the fact that Lewis makes two relevant proposals about belief: one about belief de se , another about belief de (...) re . It is the second that prompts these questions but the first that is central to his theory. (shrink)

Why are de se mental states essential? What exactly is their de se-ness needed to do? I argue that it is needed to fend off accidentalness. If certain beliefs – for example, nociceptive, proprioceptive or introspective beliefs – were not de se, then any truth they achieved would be too accidental for the subject to count as knowing. If certain intentions – intentions that are in play whenever we intentionally do anything – were not de se, then any satisfaction they (...) achieved would be too accidental for the subject to count as intentionally acting. How states hook on to their referent is relevant in a systematic but underexplored way to whether they non-accidentally achieve their aim – truth in the case of beliefs, satisfaction in the case of intentions. In the relevant cases, the way of hooking on to a referent needed to avoid being accidental is the way a de se state hooks on to its referent. (shrink)

The topic of the paper is at the intersection of recent debates on de se thought and phenomenal intentionality. An interesting problem for phenomenal intentionality is the question of how to account for the intentional properties of de se thought-contents---i.e., thoughts about oneself as oneself. Here, I aim to describe and consider the significance of a phenomenological perspective on self-consciousness in its application to de se thought. I argue that having de se thoughts can be explained in terms of the (...) ways that subjects consciously attend to themselves in experiences of thinking. Therefore, a strong form of first-person persectivalness, in which the subject is capable of self-directed control of the focus of conscious attention, is required for de se thought. But no constraints on the semantic content of such thoughts are required. The outcome of the question therefore bears importantly on both on the problem of self-reflexive self-reference and the wider problem of self-consciousness. My model suggests phenomenologically-derived conceptual constraints for the extension of minimal, background forms of self-awareness to robust, cognitive forms of self-awareness that have been of interest in recent empirical studies on self-consciousness. The framework therefore provides a way of operationalizing the concept of self-reflexive consciousness by deploying widely deployed notions from the empirical literature such as attention and minimal phenomenal selfhood, enabling a framework for empirically falsifiable hypotheses about the neural mechanisms underlying the structure of self-consciousness.

ABSTRACT Are indexical beliefs necessary to explain intentional bodily actions? De se believers argue that we cannot explain intentional bodily actions unless we appeal to indexical beliefs. De se sceptics disagree. Joining the sceptics, Cappelen and Dever have recently advanced a counterexample to de se believers's claim: a case of intentional bodily action that can be explained by their proposed indexical-free Action Inventory Model. In this paper, I argue that the de se sceptics's counterexample ultimately does not work. My argument (...) suggests that AIM cannot explain any intentional bodily action, including the alleged counterexample, because it violates two principles of action-explanation. These principles suggest that an identificational element found only in indexical beliefs is necessary to motivate intentional action. (shrink)

How should rational beliefs change over time? The standard Bayesian answer is: by conditionalization (a.k.a. Bayes’ Rule). But conditionalization is not an adequate rule for updating beliefs in “centred” propositions whose truth-value may itself change over time. In response, some have suggested that the objects of belief must be uncentred; others have suggested that beliefs in centred propositions are not subject to diachronic norms. Iargue that these views do not offer a satisfactory account of self-locating beliefs and their dynamics. A (...) third response is to replace conditionalization by a new norm that can deal with centred propositions. I critically survey anumber of new norms that have been proposed, and defend one particular approach. (shrink)

-/- Human beings are conscious not only of the world around them but also of themselves: their activities, their bodies, and their mental lives. They are, that is, self-conscious (or, equivalently, self-aware). Self-consciousness can be understood as an awareness of oneself. But a self-conscious subject is not just aware of something that merely happens to be themselves, as one is if one sees an old photograph without realising that it is of oneself. Rather a self-conscious subject is aware of themselves (...) as themselves; it is manifest to them that they themselves are the object of awareness. Self-consciousness is a form of consciousness that is paradigmatically expressed in English by the words “I”, “me”, and “my”, terms that each of us uses to refer to ourselves as such. -/- A central topic throughout the history of philosophy—and increasingly so since the seventeenth century—the phenomena surrounding self-consciousness prompt a variety of fundamental philosophical and scientific questions, including its relation to consciousness; its semantic and epistemic features; its realisation in both conceptual and non-conceptual representation; and its connection to our conception of an objective world populated with others like ourselves.

There is currently disagreement about whether the phenomenon of first-person, or de se, thought motivates a move towards special kinds of contents. Some take the conclusion that traditional propositions are unable to serve as the content of de se belief to be old news, successfully argued for in a number of influential works several decades ago.1 Recently, some philosophers have challenged the view that there exist uniquely de se contents, claiming that most of the philosophical community has been under the (...) grip of an attractive but unmotivated myth.2 At the very least, this latter group has brought into question the arguments in favor of positing special kinds of content for de se belief; I think they have successfully shown that these arguments are not as conclusive, or fully articulated, as many have taken them to be. In this paper I will address these challenges directly and I will present and defend an argument for the conclusion that the phenomenon of de se thought does indeed motivate the move to a special kind of content, content that is uniquely de se. First, I characterize a notion of de se belief that is neutral with respect to friends and foes of uniquely de se content. I then argue for a determination thesis relating de se belief to belief content: that there is no difference in de se belief without a difference in belief content. I argue that various proposals for rejecting this determination thesis are unsuccessful. In the last part of the paper, I employ this determination thesis to argue for the existence of a type of belief content that is uniquely de se. (shrink)

Inspired by Castañeda (1966, 1968), Perry (1979) and Lewis (1979) showed that a specific variety of singular thoughts, thoughts about oneself “as oneself” – de se thoughts, as Lewis called them – raise special issues, and they advanced rival accounts. Their suggestive examples raise the problem of de se thought – to wit, how to characterize it so as to give an accurate account of the data, tracing its relations to singular thoughts in general. After rehearsing the main tenets of (...) two contrasting accounts – a Lewisian one and a Perrian one – in the first section of this paper, in the second I will present a proposal of my own, which is a specific elaboration of the Perrian account. In the first section I will indicate some weaknesses of Perry’s presentation of his view; the proposal I will articulate in the second overcomes them. I will conclude with a brief discussion of reasons for preferring one or another account, in particular regarding the issue of the communication of de se thoughts. (shrink)

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)

Suppose that Paul, while looking at a tree, sees that that thing over there is a red bird. Paul is having what we may call a ‘singular’ perceptual experience. How should we characterise the representational content of his perceptual experience? I will sketch an original answer to this question, building on the internalist accounts propounded by Searle (1983. Intentionality. Cambridge University Press. Ch. 2) and Recanati (2007. Perspectival Thought. Oxford University Press. Ch. 17). Pace Searle, the content of Paul's experience (...) is not a (general) proposition. Pace Recanati, whose account draws on Lewis’s (1979. “Attitudes De Dicto and De Se.” Philosophical Review 88 (4): 513–543) internalist view of de se attitudes, it is not a property of the perceiving subject. Instead, I submit, it is a property of the perceived object. The content is the property of being a red bird, which determines a set of centred worlds whose centre (an object taken at a time) is a red bird; the object (here, the bird) is part of the relevant situation of evaluation for the experience; and the experience is veridical only if the actual world centred on the object belongs to the set of centred worlds determined by that property. I will argue that this view retains the benefits of Searle's and Recanati's accounts while improving on them. (shrink)

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)

Moderate skepticism about de se thought accepts that there is a kind of mental state which is about the thinker and is psychologically indispensable for intentional action, but rejects the claim that this kind employs an indexical way of referring. Morgan (2021) has proposed an explanatory argument meant to show that the psychological kind does employ an indexical way of referring to the thinker, on the basis of the special connection between these thoughts and the use of the first-person pronoun (...) (‘I’ in English), which does have an indexical semantics. This paper offers a clear motivation for the moderately skeptical position, shows that Morgan’s argument is based on a mistaken analysis of that special connection, and proposes a more viable alternative. However, on this alternative, the relationship between the psychological role of de se thoughts and the first person in language means Morgan’s explanatory argument cannot go through. (shrink)

I defend the claim that it is possible for thoughts to be context-sensitive. Assuming that a thought is a sentence of Mentalese and content is a function from indices to truth-values, then a thought, T, is context-sensitive IFF at least one of the following three conditions are met: T exhibits character-underdeterminacy, where T is character underdetermined iff a component of T makes an explicit reference to the context to establish content. T exhibits type-underdeterminacy, where T is type underdetermined iff there (...) are tokens of T that have distinct truth-values. T is token-underdetermined, where T is token underdetermined iff for some possible states of affairs its truth-value is indeterminate. Additionally, there must be a mechanism by which the content of T can be determined by appeal to the context. Otherwise T is not sensitive to the context. The most significant objection to the possibility of context-sensitive thoughts comes from a regress argument. The concern is that any process of removing context-sensitivity from a thought will token an additional thought. If that further thought is context-sensitive, then another thought will have to be tokened. This process will only terminate when a non-context-sensitive thought is arrived at. Yet this seems to show that context-sensitivity in thought, if possible, can only be a contingent, detachable feature of thoughts. To counter this argument, I will present three versions of context-sensitive thought, mirroring each of -. These views make use of a range of relationships between thoughts and their contents or extensions that are affected by the context, but I will argue they do not require the generation of an additional thought. This provides a range of views on which thoughts can be treated as essentially context-sensitive. (shrink)

In developing a theory of consciousness, one of the main problems has to do with determining what distinguishes conscious states from non-conscious ones—the delimitation problem. This paper explores the possibility of solving this problem in terms of self-awareness. That self-awareness is essential to understanding the nature of our conscious experience is perhaps the most widely discussed hypothesis in the study of consciousness throughout the history of philosophy. Its plausibility hinges on how the notion of self-awareness is unpacked. The idea that (...) consciousness involves self-awareness has been understood in two different ways: either as awareness of oneself—the subject of experience—or as awareness of the conscious episode itself. In this paper I argue (i) that every experience concerns the subject in a very specific way, involving what I will call ‘perspectival de se representation’, and (ii) that there is no need to appeal to the experience itself in order to characterize the awareness within that experience. The view I articulate explains the subjective nature of experience without over-intellectualizing it, accommodates the phenomenology of experience, and dispels any doubt about the need to find the self in introspection.

Among the virtues of relationist approaches to Frege’s puzzle is that they put us in a position to outline structural features of the puzzle that were only implicit in earlier work. In particular, they allow us to frame questions about the relation between the explanatory roles of sense and sameness of sense. In this paper, I distinguish a number of positions about that relation which have not been clearly distinguished. This has a few pay-offs. It allows us to shed light (...) on recent controversies about the ‘essential indexical’, and it also allows us to see what’s at stake between relationists and their opponents. When we see what’s at stake, we can see that we have reason to adopt an account of cognitive significance that incorporates elements of both relationist and Fregean approaches. (shrink)

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.

A traditional view holds that the self-concept is essentially indexical. In a highly influential article, Ruth Millikan famously held that the self-concept should be understood as a Millian name with a sui generis functional role. This article presents a novel explanatory argument against the Millian view and in favor of the indexical view. The argument starts from a characterization of the self-concept as a device of information integration. It then shows that the indexical view yields a better explanation of the (...) integration function than the Millian view. The resulting account can rebut Millikan’s objections and it has broader implications for the debate on the essential indexical. (shrink)

Tarski's analysis of the concept of truth gives rise to a hierarchy of languages. Does this fragment the concept all the way to philosophical unacceptability? I argue it doesn't, drawing on a modification of Kaplan's theory of indexicals.

What is objectivity? What would it take to have objective representations and do we have what it takes? This paper aims to contribute to answering these questions. To this end, it isolates one relevant sense of objectivity and proposes a generalization of standard frameworks of representational content in order to engage with the question in a way that is rhetorically fair. Armed with a general conception of perspectival content, taken from the literature on centred or de se content, the paper (...) articulates one necessary condition for objective representation: the possession of objective concepts and therefore objective contents. Two ways of meeting this condition are discussed in an exploratory way. (shrink)

What is the relationship between Frege’s puzzle and the puzzle of the de se? An increasingly influential view claims that the de se puzzle is merely an instance of Frege’s puzzle and that the idea that de se attitudes pose a distinctive theoretical challenge rests on a myth. Here we argue that this view is misguided. There are important differences between the two puzzles. First, unlike Frege puzzle cases, de se puzzle cases involve unshareable Fregean senses. Second, unlike Frege puzzle (...) cases, de se puzzle cases cannot be resolved by objective information alone. Further, there seem to be pure cases of each puzzle: instances of the de se puzzle which do not have a Fregean structure, and instances of Frege’s puzzle, which do not involve de se attitudes. We conclude that the two puzzles are fundamentally different and that the traditional theory of attitudes needs to be amended. (shrink)

In this paper, I assess whether indexical attitudes, e.g. beliefs and desires, have any special properties or present any special challenge to theories of propositional attitudes. I being by investigating the claim that allegedly problematic indexical cases are just instances of the familiar phenomenon of referential opacity. Regardless of endorsing that claim, I provide an argument to the effect that indexical attitudes do have a special property. My argument relies on the fact that one cannot account for what is it (...) to share someone else’s indexical attitudes without rejecting some plausible thesis about propositional attitudes. In the end, I assess Herman Cappelen and Josh Dever’s considerations on intentional action and extract an argument from them that could – if successful – neutralize my own. I finish by arguing that their argument has an important flaw, thus failing to convince us that indexical attitudes are just as ordinary as any other. (shrink)

This paper critically examines color relationalism and color relativism, two theories of color that are allegedly supported by variation in normal human color vision. We mostly discuss color relationalism, defended at length in Jonathan Cohen's The Red and the Real, and argue that the theory has insuperable problems.

Lewis’s Principal Principle says that one should usually align one’s credences with the known chances. In this paper I develop a version of the Principal Principle that deals well with some exceptional cases related to the distinction between metaphysical and epistemic modal­ity.

In doing so, I defuse the Doomsday Argument that the end of the world is likely to be nigh. (...) GPI Working Paper No. 8-2021. (shrink)

De se thoughts have traditionally been seen to be exceptional in mandating a departure from orthodox theories of attitudes. Against this, skeptics about the de se have argued that the de se phenomena demand no more of our theories of attitudes than traditional Frege cases. In this camp one view is that the de se can be accounted for by MOPs in the same way that MOPs can account for how it can be rational to believe, for instance, ”Hesperus is (...) shining” while also believing ”Phosphorus is shining.” This paper formulates some minimal conditions that de se MOPs must have in order to explain the relevant de se phenomena. Some potential replies are answered. I conclude that de se MOPs are not exceptional. (shrink)

Tradition has it that first-person thought is somehow special. It is also commonplace to maintain that the first-person concept obeys a rule of reference to the effect that any token first-person thought is about the thinker of that thought. Following Annalisa Coliva and, more recently, Santiago Echeverri, I take the specialness claim to be the claim that thinking a first-person thought comes with a certain guarantee of its pattern of reference. Echeverri maintains that such a guarantee is explained by a (...) fairly flatfooted interpretation of the thinker-reflexive rule. I argue, however, that the explanatory aspirations of the thinker-reflexive rule are fulfilled only if we accept an epistemically loaded gloss on the notion of a thinker of a thought featuring the rule. That gloss is unpacked in terms of the subject’s ability to be acquainted with the phenomenal character of their thoughts. (shrink)

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...) (1958) thesis that the predictive power of a scientific theory is directly proportional to its explanatory potential, and vice versa. (shrink)

This paper argues for a moderate form of essentialism about indexical thought. According to this moderate essentialism, there is a significant category of intentional action that necessarily involves indexical thought. This category of action is navigation, that is, intentionally moving from one location to another by using public information about the world such as a map or a set of directions. It is shown that anti-essentialists face a challenge in accounting for this kind of action without accepting the involvement of (...) indexical thought or something equivalent. The conclusion that navigation necessarily requires indexical thought is neutral on the strong essentialist claim that there is a special class of indexical propositional attitudes that mandate rejecting standard theories of propositional attitudes. The conclusion is also neutral on the strong essentialist claim that any kind of intentional action necessarily requires indexical thought. (shrink)

“I”‐thought is often taken to have a special cognitive significance, with “I” symbolising a subjective way of thinking about oneself that is inapt for communication. In this paper I argue that the way one thinks of oneself in “I”‐thought is immaterial to the meaning of “I,” for in general the psychological role associated with a referential expression is separable from its meaning. With respect to “I,” I suggest that its meaning consists in an interpersonal way of fixing its reference in (...) a context, which is accessible to the speaker and the hearer. Consequently, “I” would have a dual cognitive significance. (shrink)
