By playing a crucial role in settling open issues in the philosophical debate about logical consequence, logical evidence has become the holy grail of inquirers investigating the domain of logic. However, despite its indispensable role in this endeavor, logical evidence has retained an aura of mystery. Indeed, there seems to be a great disharmony in conceiving the correct nature and scope of logical evidence among philosophers. In this paper, I examine four widespread conceptions of logical evidence to argue that all (...) should be reconsidered. First, I argue that logical apriorists are more tolerant of logical evidence than empiricists. Second, I argue that evidence for logic should not be read out of natural language. Third, I argue that if logical intuitions are to count as logical evidence, then their evidential content must not be propositional. Finally, I argue that the empiricist proposal of treating experts' judgments as evidence suffers from the same problems as the rationalist conception. (shrink)

A speaker’s use of a sentence does more than contribute a content to a conversation. It also expresses the speaker’s attitude. This essay is about which attitude or attitudes are expressed by using an interrogative sentence to ask a question. With reference to eight lines of data about how questions are circulated in conversation, it is argued that a desire to know the question’s answer(s) is expressed.

This paper draws a line of demarcation between fallibilism and infallibilism. Taking Cartesian Infallibilism as a guide, it advances a picture of infallibilism whereby infallible knowledge requires, among other conditions, luminosity of a truth-guaranteeing property. Some implications for contemporary theories of knowledge are explored.

Self-referential sentences have troubled our understanding of language for centuries. The most famous self-referential sentence is probably the Liar, a sentence that says of itself that it is false. The Liar Paradox has encouraged many philosophers to establish theories of truth that manage to give a proper account of the truth predicate in a formal language. Kripke’s Fixed Point Theory from 1975 is one famous example of such a formal theory of truth that aims at giving a plausible notion of (...) truth by allowing truth value gaps. However, not only the concept of truth gives rise to paradoxes. A syntactical treatment of epistemic notions like belief and knowledge leads to contradictions that very much resemble the Liar Paradox. Therefore, it seems to be fruitful to apply the established theories of truth to epistemic concepts. In this paper, I will present one such attempt of solving the epistemic paradoxes: I adapt Kripke’s Fixed Point Theory and interpret truth, knowledge and belief within the framework of a partial logic. Thereby I find not only the fixed point of truth but also the fixed points of knowledge and belief. In this fixed point, the predicates of truth, belief and knowledge find their definite interpretation and the paradoxes are avoided. (shrink)

A mental state is luminous if, whenever an agent is in that state, they are in a position to know that they are. Following Timothy Williamson's Knowledge and Its Limits, a wave of recent work has explored whether there are any non‐trivial luminous mental states. A version of Williamson's anti‐luminosity appeals to a safety‐theoretic principle connecting knowledge and confidence: if an agent knows p, then p is true in any nearby scenario where she has a similar level of confidence in (...) p. However, the relevant notion of confidence is relatively underexplored. This paper develops a precise theory of confidence: an agent's degree of confidence in p is the objective chance they will rely on p in practical reasoning. This theory of confidence is then used to critically evaluate the anti‐luminosity argument, leading to the surprising conclusion that although there are strong reasons for thinking that luminosity does not obtain, they are quite different from those the existing literature has considered. In particular, we show that once the notion of confidence is properly understood, the failure of luminosity follows from the assumption that knowledge requires high confidence, and does not require any kind of safety principle as a premise.

This paper explores the prospects for a Pritchardean epistemological disjunctivist account of memory knowledge. We begin by providing an overview of Duncan Pritchard's epistemological disjunctivist account of perceptual knowledge, as well as the theoretical advantages of such an account. Drawing on that account, we present and motivate our own Pritchardean epistemological disjunctivist account of memory knowledge. After distinguishing different sorts of memory and the different roles that memory can play in knowledge acquisition, we set out our account and argue that (...) the case for epistemological disjunctivism enjoys parity with the case for epistemological disjunctivism of perceptual knowledge. We also consider objections to our account. The first is from Joe Milburn and Andrew Moon, who argue against a general epistemological disjunctivism of memory on the basis of differences in memory types. The second objection arises from a Radford-like case whereby one's true belief is from memory even though one lacks rational support that is reflectively accessible to one. (shrink)

In his latest book Mechanical Choices, Michael Moore provides an explication and defence of the idea that responsibility comes in degrees. His account takes as its point of departure the view that free action and free will consist in the holding of certain counterfactuals. In this paper, I argue that Moore’s view faces several familiar counterexamples, all of which serve to motivate Harry Frankfurt’s classic insight that whether and to what extent one is responsible for one’s action has more to (...) do with what actually caused that action than with what one could or couldn’t have done instead. I then go on to sketch an alternative approach to degrees of responsibility that takes seriously this insight. I’ll argue that Moore ought to be sympathetic to this approach, inasmuch as it combines two familiar Moorean ideas: the idea that causal contribution comes in degrees, and the idea that acting freely is compatible with, and indeed entails, the fact that one’s action was caused by prior states of affairs.

Epistemic absolutism holds that knowledge‐that is ungradable, while epistemic gradualism argues the opposite. This paper purports to remodel the gradualism/absolutism debate. The current model initiated by Stephen Hetherington fails to capture the genuine divergence between the two views, which makes the debate equivocal, and the gradualist side lacks appeal. I propose that the remodeled debate should focus on whether knowledge‐that is a ‘threshold concept’ or a ‘spectrum concept’. That is, whether there is a threshold distinguishing knowledge from non‐knowledge. The reconstructed (...) model enjoys significant advantages as it enables the debate to be more balanced and philosophically interesting. (shrink)

Epistemological disjunctivists hold that perceiving subjects have “reflective access” to factive perceptual support for belief. However, little has been done to elaborate the intended notion of reflection, or introspective awareness more generally. Moreover, critics have pointed out that the disjunctivist conception of “reflective access” can seem vulnerable to varieties of Williamson’s anti-luminosity argument. In this paper I defend disjunctivism from this charge, arguing that it holds the resources for a potent defense of the claim that knowledge of perceptual states is (...) luminous. Indeed, I argue that appreciating the relation between disjunctivism and luminosity sheds critical light on how the disjunctivist conceives of perceptual support for belief. (shrink)

In this paper I propose and motivate a logic of the interdefined concepts of making true and control, understood as intensional propositional operators to be indexed to an agent. While bearing a resemblance to earlier logics in the tradition, the motivations, semantics, and object language theory differ on crucial points. Applying this logic to widespread formal theories of agency, I use it as a framework to argue against the ubiquitous assumption that the strongest actions or options available to a given (...) agent must always be pairwise incompatible. The conclusion is that this assumption conflicts with failures of higher order control of agents over their degree or precision of control, failures exhibited by such imperfect agents as ourselves. I discuss models in this setting for understanding such imperfectly self-controlling agents. In an appendix, I prove several relevant results about the logic described, including soundness and completeness both for it and for certain natural extensions. (shrink)

Can scientific evidence outstretch what scientists have mentally entertained, or could ever entertain? This article focuses on the plausibility and consequences of an affirmative answer in a special case. Specifically, it discusses how we may treat automated scientific data-gathering systems—especially AI systems used to make predictions or to generate novel theories—from the point of view of confirmation theory. It uses AlphaFold2 as a case study.

Intentional action is, in some sense, non-accidental, and one common way action theorists have attempted to explain this is with reference to control. The idea, in short, is that intentional action implicates control, and control precludes accidentality. But in virtue of what, exactly, would exercising control over an action suffice to make it non-accidental in whatever sense is required for the action to be intentional? One interesting and prima facie plausible idea that we wish to explore in this paper is (...) that control is non-accidental in virtue of requiring knowledge—either knowledge-that or knowledge-how (e.g., Beddor and Pavese 2021; cf., Setiya 2008; 2012 and Habgood-Coote 2018). We review in detail some key recent work defending such knowledge-centric theories of control, and we show that none of these accounts holds water. We conclude with some discussion about how control opposes the sort of luck intentional action excludes without doing so by requiring knowledge (that- or how). (shrink)

The knowledge account of assertion construes assertion as subject to constitutive norms. In its standard version, it combines a wide scope obligation not to assert p without knowing p, with narrow scope principles specifying conditions under which it is permissible to assert p, where the notions of obligation and permission are duals and behave uniformly for variable p. It is argued that, given natural assumptions about the logic of ‘ought’, the account proves incoherent. The argument generalizes to accounts that substitute (...) other factive notions for knowledge. A recent non‐standard version of the knowledge account employs proposition‐relative norms and circumvents the problem. However, it still leads to intolerable combinations of verdicts. Again, the problem arises because knowledge is factive, and it generalizes to other factive notions. It is shown that non‐factive accounts face none of the diagnosed difficulties and can do much of the explanatory work that the knowledge account is alleged to do. (shrink)

A familiar anti-sceptical response (à la Sosa) to radical sceptical scenarios employs the safety of knowledge. Radical sceptical scenarios are purported to be too modally remote to really threaten knowledge of ordinary propositions. Why? Because knowledge requires safety, and safety requires the target belief to be true in all nearby possible worlds, but radical sceptical scenarios purportedly take place at distant possible worlds. Hence, the safety theorist claims that radical sceptical scenarios don’t challenge our knowledge of ordinary propositions. But it's (...) alleged by Sosa and others that there's one radical sceptical scenario that can’t be dismissed so easily: the dream scenario. After all, unlike evil demons and brains in vats, ‘dreaming is a daily part of our lives…it is too close for comfort’. In this paper, I sketch an argument to the effect that there's good reason to think that the dream of dream scepticism describes a modally remote possibility, in which case I argue that if the safety-based anti-sceptical response is successful against the evil demon sceptical scenario, the brain in a vat sceptical scenario, and other Cartesian sceptical scenarios in this mould, then it's successful against the dream sceptical scenario as well.

This paper discusses a scenario borrowed from Williamson (2000) and repurposes it to argue for the possibility of conflict between two _prima facie_ categorical norms of epistemic rationality: the norm to respect one’s evidence and the norm to be coherent. It is argued, _pace_ Williamson, that in the conflict defining the scenario, the evidence norm overrides the coherence norm; that a rational agent with our evidence would lack evidence about some of their own credences; and that for agents whose evidence (...) is limited in this way, incoherence fails to entail irrationality. The above possibility claim has also been defended by Worsnip (2018), albeit on a quite different premise set and in conjunction with a coherence-centered account of epistemic rationality that issues predictions incompatible with those licensed by the evidence-centered account recommended here, as illustrated towards the end of the paper.

I will discuss a variety of cases such that the subject's believing truly is somewhat of an accident, but less so than in a Gettier case. In each case, this is because her reasons are not ultimately undefeated full stop, but they are ultimately undefeated with certain qualifications. For example, the subject's reasons might be ultimately defeated considered in themselves but ultimately undefeated considered as a proper part of an inference to the best explanation that is undefeated without qualification. In (...) each section of the paper, I consider different qualifications and show how in each case we get an epistemic standing I call “coach-class knowledge”. First-class knowledge requires justifying reasons that are undefeated without qualification. Coach-class knowledge only requires qualified lack of defeat. I will use this distinction to bring debates over knowledge from falsehood and fake barns to an ecumenical resolution. In both cases, the subject enjoys coach-class rather than first-class knowledge. I will also show that the defeasible reasoning tradition can better account for graded accidental truth than safety theories. (shrink)

Among the main reactions to scepticism, fallibilism is certainly the most popular nowadays. However, fallibilism faces a very strong and well-known objection. It has to grant that concessive knowledge attributions—assertions of the form “I know that p but it might be that not p”—can be true. Yet, these assertions plainly sound incoherent. Fallibilists have proposed to explain this incoherence pragmatically. The main proponents of this approach appeal to Gricean implicatures (Rysiew in Noûs 35(4):477514, 2001; Dougherty and Rysiew in Philos Phenomenol (...) Res 78(1):123132, 2009; Dougherty and Rysiew in Synthese 181(3):395403, 2011). Very recently, some philosophers have observed that fallibilists can also explain this apparent incoherence pragmatically if they embrace a (context-sensitive) certainty norm for assertion (Petersen in Synthese 196(11):4691–4710, 2019; Beddor in Philos Impr 20(8), 2020; Vollet in Dialectica 74:3, 2020). In this paper, I argue for the superiority of this latter explanation over its older rivals. (shrink)

This essay uses a puzzle about assertion and time to explore the pragmatics, semantics, and epistemology of future discourse. The puzzle concerns cases in which a subject is in a position to say, at an initial time t, that it will be that ϕ, but is not in a position to say, at a later time t′, that it is or was that ϕ, despite not losing or gaining any relevant evidence between t and t′. We consider a number of (...) approaches to the puzzle and defend the view that subjects in these cases lose knowledge simply by moving through time. (shrink)

In Truth and Objectivity, Crispin Wright argues that because truth is a distinctively normative property, it cannot be as metaphysically insubstantive as deflationists claim. We offer a reconstruction of Wright’s Inflationary Argument that highlights the steps required to establish its inflationary conclusion. We argue that if a certain metaphysical and epistemological view of a given subject matter is accepted, a local counterexample to the Inflationary Argument can be constructed. As a case study we focus on the domain of basic taste. (...) We develop two variants of a subjectivist and relativist metaphysics and epistemology that seem palatable in that domain and we show that the Inflationary Argument doesn’t go through in the domain of basic taste thus construed. We conclude by briefly discussing the significance of this result for the debate on alethic pluralism. (shrink)

With few exceptions, theorists analyze group attitudes in terms of the attitudes of members. In Epstein 2015, 2019a, 2019b, I argued that this thesis (which I call "MEMBERS ONLY")—and hence any theory that analyzes group attitudes in terms of member attitudes—is mistaken: the attitudes of many groups are ontologically determined by a broader range of factors than member attitudes. My aim in the present paper is to consider new arguments against MEMBERS ONLY. I argue that arguments based on the "hypothesis (...) of the extended mind" are not persuasive for challenging MEMBERS ONLY, but reinforce my earlier arguments, and I also propose new arguments from group content externalism are more promising.

Justified belief is a core concept in epistemology and there has been an increasing interest in its logic over the last years. While many logical investigations consider justified belief as an operator, in this paper, we propose a logic for justified belief in which the relevant notion is treated as a predicate instead. Although this gives rise to the possibility of liar-like paradoxes, a predicate treatment allows for a rich and highly expressive framework, which lives up to the universal ambitions (...) of investigating epistemological concepts. We start with a base theory for justified belief, and then systematically present putative additional axioms for justified belief. We provide an overview of consistency results when the additional principles are added to the base theory, and discuss their philosophical plausibility. (shrink)

Testimony is a source of knowledge. A speaker asserts what a hearer may therefore come to know. Assertion has widely been treated as the exclusive or at least the paradigmatic vehicle for testimony. I argue that we testify not only by asserting something, but also by taking something for granted within some other utterance. In philosophy of language, this is called semantic presupposition. The very reasons leading theorists of testimony have for thinking that assertion can be testimony are equally reasons (...) for thinking semantic presupposition can be testimony. (shrink)

Evidence is often taken to be “normative” for doxastic agents. What accounts for the normativity of evidence? According to the view that I’ll call “evidential minimalism”, there is a close connection between strong evidence for the truth of p and a normative reason to believe p: evidence is either itself a normative reason for belief, or evidence gives rise to such a reason when certain other minimal conditions are met. In this paper, I argue against evidential minimalism. I will argue (...) that there are cases where: (i) an individual S possesses strong evidence E for the truth of p at time t, (ii) all other minimal conditions for the normativity of E are met at t, (iii) S doesn’t believe p at t, yet (iv) S isn’t open to any form of criticism on account of (i)-(iii) at t. I will then formulate a plausible linking claim connecting openness to criticism and the existence of normative reasons for belief. The minimalist can either accept or reject this linking claim. I will argue that, either way, the minimalist view falters. (shrink)

Strevens’s Thinking Off Your Feet promises to vindicate philosophical analysis. My comments take a narrow, critical focus. I argue that Strevens doesn’t deliver on this promise. Given my understanding of (i) what is required from a vindication of philosophical analysis and (ii) Strevens’s grounds for ‘optimism’ about philosophical analysis, Strevens hasn’t done enough to vindicate philosophical analysis. Indeed, Strevens’s supposed grounds for optimism about armchair philosophy in fact provide motivation for philosophical analysis to give up some ground to experimental philosophy. (...) Although my comments are critical, my overall view of the book is not. Strevens does important and interesting work presenting and analysing various models of how armchair philosophy might work and what it might achieve. The book deserves a central place in future discussions about these issues. (shrink)

Responding to the critical comments by the symposiasts Julien Dutant, Niccolò Rossi, Martin Smith, Daniel Waxman, and Yiwen Zhan, I further elaborate, refine, and defend the account of epistemic justification I advanced in my book Justification as Ignorance (Oxford: Oxford University Press, 2021). Central issues tackled here include logical omniscience and non-normal epistemic logics, the luminosity of epistemic justification, methods for telling what one is in no position to know, and the relation between doxastic and propositional justification.

According to evidentialists about inferential justification, an agent’s evidence—and only her evidence—determines which inferences she would be justified in making, whether or not she in fact makes them. But there seem to be cases in which two agents would be justified in making different inferences from a shared body of evidence, merely in virtue of the different competences those agents possess. These sorts of cases suggest that evidence does not have the pride of place afforded to it by evidentialists; competence (...) seems to play at least as important a role as evidence in explaining which inferences an agent would be justified in making. -/- In this paper, I consider how two versions of evidentialism about inferential justification might try to account for the role of competence in inference, and I present problems specific to each version. I end by sketching and briefly defending an alternative to these evidentialist views, “inferential dogmatism”. While dogmatic views have gotten some attention in debates around non-inferential justification, they have largely been ignored in debates around inferential justification and are to that extent novel.

The proper function of the heart is pumping the blood. According to what we call the type etiological view, this is because previous tokens of the type HEART were selected for pumping the blood. Nanay :412–431, 2010) argues that the type etiological view is viciously circular. He claims that the only plausible accounts of trait type individuation use proper functions, such that whenever the type etiological view is supplemented with a plausible account of trait type individuation, the result is a (...) view that uses proper functions to explain proper functions. We refine this objection, and argue that Nanay at most establishes a potentially benign definitional circularity. However, we show that the type etiological view’s reliance on types nevertheless generates a vicious regress. Hence the type etiological view is false. We reject dispositional and modal alternatives to the type etiological view for the reason that they either cannot accommodate malfunction, or do so at the cost of proliferation; and then formulate a novel token etiological view that overcomes both problems because it makes no reference to trait types.

According to a thesis famously associated with Anscombe'sIntention, knowledge is a necessary condition of intentional action: when acting intentionally, we know what we are doing. Call this the Agential Knowledge thesis. The Agential Knowledge thesis remains, of course, controversial. Furthermore, as even some of its proponents acknowledge, it can appear puzzling: Why should acting intentionally require knowing what you are doing? My aim in this paper is to propose an explanation and defence of the Agential Knowledge thesis, based on the (...) idea that acting intentionally is exercising control, in a relevant sense. My argument rests on two things: first, articulating a modal conception of the relevant sense of control, and, secondly, arguing that agential knowledge is distinctively practical. As I explain, the truth of the Agential Knowledge thesis opens promising paths for future work in the philosophy of action. (shrink)

This paper is about a tension between two theses. The first is Value of Evidence: roughly, the thesis that it is always rational for an agent to gather and use cost‐free evidence for making decisions. The second is Rationality of Imprecision: the thesis that an agent can be rationally required to adopt doxastic states that are imprecise, i.e., not representable by a single credence function. While others have noticed this tension, I offer a new diagnosis of it. I show that (...) it arises when an agent with an imprecise doxastic state engages in an unreflective inquiry, an inquiry where they revise their beliefs using an updating rule that doesn't satisfy a weak reflection principle. In such an unreflective inquiry, certain synchronic norms of instrumental rationality can make it instrumentally irrational for an agent to gather and use cost‐free evidence. I then go on to propose a diachronic norm of instrumental rationality that preserves Value of Evidence in unreflective inquiries. This, I suggest, may help us reconcile this thesis with Rationality of Imprecision. (shrink)

Reliabilism says that knowledge must be produced by reliable abilities. Abilism disagrees and allows that knowledge is produced by unreliable abilities. Previous research strongly supports the conclusion that abilism better describes how knowledge is actually defined in commonsense and science. In this paper, I provide a novel argument that abilism is ethically superior to reliabilism. Whereas reliabilism unethically discriminates against agents by excluding them from knowing, abilism virtuously includes them.

This paper argues for two interrelated claims. The first is that the most innovative contribution of Timothy Williamson, Herman Cappelen, and Max Deutsch in the debate about the epistemology of thought experiments is not the denial of intuition and the claim of the irrelevance of experimental philosophy but the claim of epistemological continuity and the rejection of philosophical exceptionalism. The second is that a better way of implementing the claim of epistemological continuity is not Deutsch and Cappelen’s argument view or (...) Williamson’s folk psychological view. This is so because while the argument view makes the basis of the relevant classificational judgement evidentially too demanding; the folk psychological view makes it too weak and error-prone to count as an adequate explanation. Drawing from a certain reading of Aristotle’s Nichomachean Ethics that flowers in Miranda Fricker and John McDowell, I argue for the reason-responsiveness view. Like the extant views, the reason-responsiveness view vindicates the claim of epistemological continuity. But unlike the extant views, it does not share those problematic features. Further, I show that the reason-responsiveness view offers a way for champions of the claim of epistemological continuity to resist Avner Baz’s objection to the claim of epistemological continuity and his objection to the philosophical use of thought experiments while taking on board some attractive elements of his view.

That one person's modus ponens is another's modus tollens is the bane of philosophy because it strips many philosophical arguments of their persuasive force. The problem is that philosophical arguments become mere pantomemes: arguments that are reasonable to resist simply by denying the conclusion. Appeals to proof, intuition, evidence, and truth fail to alleviate the problem. Two broad strategies, however, do help in certain circumstances: an appeal to normal informal standards of what is reasonable (nisowir) and argument by interpretation. The (...) method of explication features prominently in both strategies, and the paper extends this method to apply to nisowir, introducing the concept of canonical explication. The paper illustrates the two strategies with examples of arguments from formal epistemology and suggests that an appeal to nisowir might help to defend against philosophical scepticism by shifting the burden of proof to the sceptic.

Comment on Declan Smithies's book The Epistemic Role of Consciousness (2019).

One of the most intriguing claims in Sven Rosenkranz’s Justification as Ignorance is that Timothy Williamson’s celebrated anti-luminosity argument can be resisted when it comes to the condition ~K~KP—the condition that one is in no position to know that one is in no position to know P. In this paper, I critically assess this claim.

This is the latest draft of chapter 1 of _A New Theory of Reasons for Belief: Pragmatic Foundations and Pluralistic Reasons_ (Under Contract with OUP). It outlines the view that is the focus of the book: Welfarist Pluralism. Welfarist pluralism is the view that all normative reasons for belief are grounded in wellbeing and that being in a positive epistemic state is one of the components of wellbeing. This chapter explains how one can develop a principled version of non-derivative pluralism (...) about normative reasons for belief while still accepting that theoretical reason has a single, unified pragmatic foundation. Updated 25 January 2023. (shrink)

Whereas epistemology is the philosophical theory of knowledge, its nature and scope, metaepistemology takes a step back from particular substantive debates in epistemology in order to inquire into the assumptions and commitments made by those who engage in these debates. This entry will focus on a selection of these assumptions and commitments, including whether there are objective epistemic facts; and how to characterize the subject matter and the methodology of epistemology.

Structural analogies connect Williamson’s epistemology and action theory: for example, action is the direction-of-fit mirror image of knowledge, and knowledge stands to belief as action stands to intention. These structural analogies, for Williamson, are meant to illuminate more generally how ‘mirrors’ reversing direction of fit should be understood as connecting the spectrum of our cognitive and practically oriented mental states. This paper has two central aims, one negative and the other positive. The negative aim is to highlight some intractable problems (...) with Williamson’s preferred analogical picture, which links the cognitive and the practical through the nexus of direction-of-fit mirroring. The positive aim of the paper is to propose a better alternative. In particular, we show that an achievement-theoretic proposal captures what is in common across the range of attitudes that exhibit the kind of structure that knowledge-belief, action-desire/intention do, while at the same time avoiding the problems shown to face Williamson’s proposed picture. Moreover, we draw attention to several key theoretical benefits of embracing our proposed achievement-theoretic picture, including some of the key benefits of the knowledge-first programme that Williamson’s own analogies were designed to secure.

This paper considers some puzzling knowledge ascriptions and argues that they present prima facie counterexamples to credence, belief, and justification conditions on knowledge, as well as to many of the standard meta-semantic assumptions about the context-sensitivity of ‘know’. It argues that these ascriptions provide new evidence in favor of contextualist theories of knowledge—in particular those that take the interpretation of ‘know’ to be sensitive to the mechanisms of constraint.

Being incoherent is often viewed as a paradigm kind of irrationality. Numerous authors attempt to explain the distinct-seeming failure of incoherence by positing a set of requirements of structural rationality. I argue that the notion of coherence that structural requirements are meant to capture is very slippery, and that intuitive judgments – in particular, a charge of a distinct, blatant kind of irrationality – are very imperfectly correlated with respecting the canon of structural requirements. I outline an alternative strategy for (...) explaining our patterns of normative disapproval, one appealing to feasible dispositions to conform to substantive, non-structural norms. A wide range of paradigmatic cases of incoherence, I will argue, involve manifesting problematic dispositions, dispositions that manifest across a range of cases as blatant-seeming normative failures.

Recently some philosophers have defended the thesis that naturalness, or joint-carvingness, is an aim of belief. This paper argues that there is an important class of counterexamples to this thesis. In particular, it is argued that naturalness is not an aim of our beliefs concerning what is joint carving and what is not.

The debate between relationalism and representationalism in the philosophy of perception seems to have come to a standstill where opponents radically disagree on methodological principles or fundamental assumptions. According to Fish (this volume) this is because, not unlike Kuhnian scientific paradigms, the debate displays some elements of incommensurability. This diagnosis makes advancing the debate impossible. I argue that what is hindering progress is not a clash of research programmes, but a series of misunderstandings that can be avoided by disentangling the (...) different questions each theory is invested in and by making explicit the hidden assumptions at play in the debate. One such central assumption is what I call the Superficiality Constraint. This is the idea that the phenomenal character of experience is superficial with respect to introspection. I argue that we can make progress in the debate by assessing to what extent and at what cost relationalism can accommodate this constraint. (shrink)

Objectivism is the view that how an agent ought to act depends on all kinds of facts, regardless of the agent’s epistemic position with respect to them. One of the most important challenges to this view is constituted by certain cases involving specific conditions of uncertainty—so-called three-options cases. In these cases it seems overwhelmingly plausible that an agent ought to do what is recommendable given her limited perspective, even though the agent knows that this is not objectively the best course (...) of action. The standard objectivist response to this challenge relies on a distinction between what one ought to do and what would be blameworthy or unreasonable to do. This response is affected by several problems. In this paper I introduce and defend an alternative objectivist response to the challenge. My proposal admits that in the relevant cases the agent ought to do what is recommendable given her perspective, but maintains that this diagnosis of the cases is fully compatible with objectivism. I argue that this proposal has several advantages over alternative accounts of the cases. (shrink)

Content disjunctivism is the view that veridical experience involves contents and objects that differ from those of corresponding hallucinations. On one formulation of this view, we are aware of ordinary material things in our surroundings when we experience veridically, and we are aware of mere appearances when we hallucinate. This paper proposes a way of developing this view and offers some considerations in support. Central to the proposed regimentation will be a distinction between different notions of appearance. We distinguish between (...) the notion of something merely appearing to have a property and the notion of mere appearances, which are types of objects that we can refer to and be aware of. Mere appearances are not sense data or Meinongian non-existent objects but existing objects that do not have the properties that they appear to have. These notions of appearance will be elucidated, in particular by characterizing how they are involved in hallucination and illusion. I argue that the resulting view is supported by how our mental life seems to us when we experience our environment. (shrink)

This paper explores the idea that Descartes’ cogito is a kind of diagonal argument. Using tools from modal logic, it reviews some historical antecedents of this idea from Slezak and Boos and culminates in an orginal result classifying the exact structure of belief frames capable of supporting diagonal arguments and our reconstruction of the cogito.
