I propose the Shared Presupposition Norm of Joking (SPNJ) as a constitutive norm of joke-telling. This norm suggests that a person should only tell a joke if they believe their audience shares the presuppositions—both explicit beliefs and implicit inferential connections—upon which the joke turns. Without this shared understanding, the audience would lack the necessary comprehension to appreciate the joke. I defend this norm in an analogous way to Williamson’s defense of the Knowledge Norm of Assertion by demonstrating that it explains (...) a number of patterns of joking behavior. If SPNJ is indeed a constitutive norm of joking, it provides an epistemological foothold. Jokes function as conversational explicatures serving an epistemically diagnostic function, revealing implicit and perhaps disavowed inferential dispositions of the joking community. This norm does not teach us about the subject matter of the joke, but instead illuminates the language games of the joke teller and audience. (shrink)

Sentences \(\varphi\) and \(\psi\) are _cognitive synonyms_ for one when they play the same role in one’s cognitive life. The notion is pervasive (Sect. 1 ), but elusive: it is bound to be hyperintensional (Sect. 2 ), but excessive fine-graining would trivialize it and there are reasons for some coarse-graining (Sect. 2.1 ). Conceptual limitations stand in the way of a natural algebra (Sect. 2.2 ), and it should be sensitive to subject matters (Sect. 2.3 ). A cognitively adequate individuation (...) of content may be intransitive (Sect. 3 ) due to ‘dead parrot’ series: sequences of sentences \(\varphi _1, \ldots, \varphi _n\) where adjacent \(\varphi _i\) and \(\varphi _{i+1}\) are cognitive synonyms while \(\varphi _1\) and \(\varphi _n\) are not (Sect. 3.1 ). Finding an intransitive account is hard: Fregean equipollence won’t do (Sect. 3.2 ) and a result by Leitgeb shows that it wouldn’t satisfy a minimal compositionality principle (Sect. 3.3 )._Sed contra_, there are reasons for transitivity, too (Sect. 3.4 ). In Sect. 4, we come up with a formal semantics capturing this jumble of desiderata, thereby showing that the notion is coherent. In Sect. 5, we re-assess the desiderata in its light. (shrink)

I defend an iterated knowledge condition on responsibility for outcomes: one is responsible for a consequence of one's action only if one was in a position to know that, for all one was in a position to know, one's action would have that consequence.

Abstract“Absolutely nothing,” say the radical Bayesians. “Simplifying decisions,” say the moderates. “Providing premises in practical reasoning,” say the epistemologists. “Coordinating with others,” say I. It is hard to see how to construct an adequate theory of rational behavior without using a graded notion of belief, such as credence. But once we have credence, what role is left for belief? After surveying some answers to this question, I will explore the idea that belief is in a different line of work altogether. (...) Its job is not to rationalize and explain an agent’s behavior, but to track what the agent would accept as a reason. Although some philosophers have seen the connection between belief and reasons, they have tended to see reasons as part of a theory of rational action. This locates belief in the rationalizing and explaining business, where it must vie with credence. In contrast, I argue that reasons play no essential role in an account of individual rationality; they are important because we need to coordinate with others. Credence and belief thus answer to separate needs. (shrink)

It is often assumed that theorizing in terms of natural properties is more objectively valuable than theorizing in terms of non-natural properties. But this assumption faces an explanatory challenge: explain the greater objective value of theorizing in terms of natural properties. In this paper, I answer that challenge by proposing and exploring three different accounts of the objective value of naturalness. Two appeal to constitutive natures: it is part of the constitutive nature of explanation, or of objective value, that theorizing (...) in terms of natural properties is more objectively valuable. The third appeals to the theoretical role that naturalness plays. (shrink)

On a version of consent theory that tempts many, predatory sexual relations involving significant power imbalances (e.g. between professors and students, adults and teenagers, or employers and employees) are wrong because they violate consent-centric norms. In particular, the wronged party is said to have been incapable of consenting to the predation, and the sexual wrong is located in the encounter’s nonconsensuality. Although we agree that these are sexual wrongs, we resist the idea that they are always nonconsensual. We argue instead (...) that it is possible for students, teenagers, employees, etc. to fully consent to sexually predatory encounters; denying as much renders survivors of predation vulnerable to compounding harms. Survivors face a dilemma: give up either their understanding of their experience as wrong, or their self-conception as an agent capable of consenting. We call the latter phenomenon agential demotion.

Eva Schmidt argues that facts about incoherent beliefs can be non-evidential epistemic reasons to suspend judgment. In this commentary, I argue that incoherence-based reasons to suspend are epistemically superfluous: if the subjects in Schmidt’s cases ought to suspend judgment, then they should do so merely on the basis of their evidential reasons. This suggests a more general strategy to reduce the apparent normativity of coherence to the normativity of evidence. I conclude with some remarks on the independent interest that reasons-first (...) epistemology might have within an evidentialist framework. (shrink)

This paper discusses the Uniqueness Thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

Ante la imposibilidad de alcanzar un análisis reductivo del concepto de mentira, Tobies Grimaltos y Sergi Rosell han propuesto una concepción basada en sus condiciones paradigmáticas, entre las que destaca la de engañar al oyente. La relación entre la mentira y el engaño sería, si bien fundamental para entender los casos prototípicos del concepto, meramente contingente —una tesis que tiene importantes implicaciones para su valoración moral—. Presento aquí su propuesta y avanzo tres objeciones a la misma: primero, que la teoría (...) de la mentira debería de construirse sobre una teoría de la aserción, que ya de por sí delimita lo propiamente dicho en los usos parasitarios del lenguaje (como la metáfora o la ironía). Segundo, que es preciso distinguir los usos de la mentira de sus aspectos constitutivos, entre los cuales destaca la intención de mentir, y no la de engañar. Y tercero, que un modelo paradigmático de la mentira debería de asumir una condición epistémica, y no meramente doxástica, según la cual mentir es, paradigmáticamente, decir algo que uno sabe falso.

The massive debate in philosophy and psychology and neuroscience about higher-order theories of consciousness has not adequately distinguished between the following two claims. (Necessary Awareness): For any conscious mental state M and subject S, if S is in M, then S is aware of M. (The Higher-Order Theory): For any conscious mental state M and subject S, if S is in M, then M is conscious because S is aware of M. -/- While I will assume that the first claim (...) is true, I will argue that we should reject higher-order theories of consciousness. We should turn them on their head to go with the following theory: (The Ascending Road): For any conscious mental state M and subject S, if S is in M, then S is aware of M because M is conscious.

Leading philosophical models of curiosity represent it as a desiderative attitude whose content is a question, and which is satisfied by knowledge of the answer to that question. I argue that these models do not capture the distinctive character of a form of curiosity that I call 'erotic curiosity'. Erotic curiosity addresses itself not to a question but to an object whose significance for the inquirer is affective as well as epistemic. This form of curiosity is best understood by analogy (...) to erotic love as theorized by Plato in the Symposium. (shrink)

Infallibilism leads to skepticism, and fallibilism is plagued by the threshold problem. Within this narrative, the pragmatic turn in epistemology has been marketed as a way for fallibilists to address the threshold problem. In contrast, pragmatic versions of infallibilism have been left unexplored. However, I propose that going pragmatic offers the infallibilist a way to address its main problem, the skeptical problem. Pragmatic infallibilism, however, is committed to a shifty view of epistemic certainty, where the strength of a subject’s epistemic (...) state can vary depending upon the practical context. Pragmatic views of epistemic strength are quite radical so the argumentative goal of my discussion is to argue for its plausibility, thereby arguing for the plausibility of pragmatic infallibilism. To do so, I discuss the role that the framing of decision problems and the construction of our deliberative attitudes have in our theories of rational choice. And I explore a way in which these necessary components of a normative theory of rationality can be used to motivate pragmatic views of evidential support. Finally, since the plausibility of our pragmatic account will depend upon the plausibility of a constructive account of rational choice, I conclude by comparing the adequacy of the constructive account with orthodox Bayesian and knowledge-based accounts.

In this paper, we consider recent attempts to metaphysically explain agentive modality in terms of conditionals. We suggest that the best recent accounts face counterexamples, and more worryingly, they take some agentive modality for granted. In particular, the ability to perform basic actions features as a primitive in these theories. While it is perfectly acceptable for a semantics of agentive modal claims to take some modality for granted in getting the extension of action claims correct, a metaphysical explanation of agentive (...) modality cannot, at least not in the way that conditional approaches to agentive modality do. We argue that this problem was present even in the classical conditional analysis. By a pessimistic induction, we suggest that, probably, no conditional approach to agentive modality will succeed.

This paper offers a systematic classification and characterization of speech acts and their norms. Recently, the normative approach has been applied to various speech acts, most notably to constatives. I start by showing how the work on the norms of assertion has influenced various approaches to the norms of other speech acts. I focus on the fact that various norms of assertion have different extensions, i.e., they denote different clusters of illocutions as belonging to an assertion. I argue that this (...) has consequences for theorising about norms of other speech acts and generates certain arbitrary divisions. In the central part, I analyse two groups of speech acts. Firstly, ordinary speech acts, like predictions or retractions. Secondly, I indicate how the normative view can be extended to so-called ancillary speech acts, like presuppositions or implicatures. I end with a discussion of possible extensions of the normative approach, focusing on the debate on lying. (shrink)

The belief norm of academic publishing states that researchers should believe certain claims they publish. The purpose of this paper is to defend the belief norm of academic publishing. In its defense, the advantages and disadvantages of the belief norm are evaluated for academic research and for the publication system. It is concluded that while the norm does not come without costs, academic research systemically benefits from the belief norm and that it should be counted among those that sustain the (...) practice of academic publishing.

Reasons rationalize beliefs. Reasons, when all goes well, turn true beliefs into knowledge. I am interested in the relationship between these aspects of reasons. Without a proper understanding of their relationship, the theory of knowledge will be less illuminating than it ought to be. I hope to show that previous accounts have failed to account for this relationship. This has resulted in a tendency to focus on justification rather than knowledge. It has also resulted in many becoming skeptical about the (...) prospects for an analysis of knowledge. The skepticism is misplaced and the tendency can be fixed without sacrificing any insights. The solution is to see how good reasons (in a sense to be articulated) are apparent (in a sense to be articulated) to the knowing subject. Once this claim is unpacked, we see that it is an illuminating analysis of knowledge in terms of distinct but intimately related aspects of epistemic assessment. It helps us see the value of knowledge (over and above true belief) and it affords us a unified, “reasons-first” metaepistemology. The resulting picture is neither a familiar kind of internalism or externalism. (shrink)

Existing analyses of disinformation tend to embrace the view that disinformation is intended or otherwise functions to mislead its audience, that is, to produce false beliefs. I argue that this view is doubly mistaken. First, while paradigmatic disinformation campaigns aim to produce false beliefs in an audience, disinformation may in some cases be intended only to prevent its audience from forming true beliefs. Second, purveyors of disinformation need not intend to have any effect at all on their audience’s beliefs, aiming (...) instead to manipulate an audience’s behavior through alteration of sub-doxastic states. Ultimately, I argue that attention to such non-paradigmatic forms of disinformation is essential to understanding the threat disinformation poses and why this threat is so difficult to counter.

This work investigates intuitions' nature, demonstrating how philosophers can best use them in epistemology. First, the author considers several paradigmatic thought experiments in epistemology that depict the appeal to intuition. He then argues that the nature of thought experiment-generated intuitions is not best explained by an a priori Platonism. Second, the book instead develops and argues for a thin conception of epistemic intuitions. The account maintains that intuition is neither a priori nor a posteriori but multi-dimensional. It is an intentional (...) but non-propositional mental state that is also non-conceptual and non-phenomenal in nature. Moreover, this state is individuated by its progenitor, namely, the relevant thought experiment. Third, the author provides an argument for the evidential status of intuitions based on the correct account of the nature of epistemic intuition. The suggestion is the fitting-ness approach: intuition alone has no epistemic status. Rather, intuition has evidentiary value as long as it fits well with other pieces into a whole, namely, the pertinent thought experiment. Finally, the book addresses the key challenges raised by supporters of anti-centrality, according to which philosophers do not regard intuition as central evidence in philosophy. To that end, the author responds to them, showing that they fail to affect the account of intuition developed in this book. This text appeals to students and researchers working in epistemology.

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

Two traditions in action theory offer different accounts of what distinguishes intentional action from mere behavior. According to the causalist tradition, intentional action has certain distinguished causal antecedents, and according to the Anscombian tradition, intentional action has certain distinguished epistemological features. I offer a way to reconcile these ostensibly conflicting accounts of intentional action by way of appealing to “ability-constituting knowledge”. After explaining what such knowledge is, and in particular its relationship to inadvertent virtue and knowledge-how, I suggest that, among (...) other things, appealing to ability-constituting knowledge can help us flesh out what it is for an agent’s reasons to non-deviantly cause and sustain her purposive behavior. (shrink)

I argue that knowledge can be seen as a quality standard that governs our sharing and storing of information. This standard satisfies certain functional needs, namely it allows us to share and store trustworthy information more easily. I argue that this makes knowledge a social kind, similar in important ways to other social kinds like money. This provides us with a way of talking about knowledge without limiting ourselves to the concept of knowledge. I also outline three ways in which (...) this view of knowledge can shed light on familiar epistemological problems: it can explain why knowledge is the norm of assertion, it can help us carve out the harm associated with testimonial injustice, and it can provide us with a clear analysis of the dangers associated with spreading misinformation.

According to the sensitivity account of knowledge, S knows that p only if S's belief in p is sensitive in the sense that S would not believe that p if p were false. It is widely accepted that the sensitivity condition should be relativized to belief-formation methods to avoid putative counterexamples. A remaining issue for the account is how belief-formation methods should be individuated. In this paper, I argue that while a coarse-grained individuation is still susceptible to counterexamples, a fine-grained (...) individuation makes the target belief trivially insensitive. Therefore, there is no principled way of individuating belief-formation methods that helps the sensitivity account to accommodate different cases. (shrink)

This paper aims to solve a puzzle for instrumental conceptions of epistemic normativity. The puzzle is this: if the usefulness of epistemic norms explains their normative grip on us, why does it seem improper to violate these norms even when doing so would benefit us? To solve this puzzle, we argue that epistemic instrumentalists must adopt a more social approach to normativity. In particular, they should not account for the nature of epistemic normativity by appealing to the goals of individual (...) agents. Rather, they should appeal to norms or rules of inquiry that serve our collective goals. We argue that epistemic normativity grows out of our need to promote a deep kind of coordination in our basic epistemic practices. By subscribing to an appropriate system of norms, we can coordinate epistemic rule-following across the community. This makes testimony more trustworthy and reliable. This account not only solves a puzzle about epistemic instrumentalism but also sheds new light on the foundations of normativity and emphasizes the need for a truly social epistemology. (shrink)

On a Cartesian conception of the mind, I could be a solitary being and still have the same mental states as I currently have. This paper asks how the lives of other people fit into this conception. I investigate the second-person perspective—thinking of others as ‘you’ while engaging in reciprocal communicative interactions with them—and argue that it is neither epistemically nor metaphysically distinctive. I also argue that the Cartesian picture explains why other people are special: because they matter not just (...) for the effect that they have on us. (shrink)

Self-verifying judgments like _I exist_ seem rational, and self-defeating ones like _It will rain, but I don’t believe it will rain_ seem irrational_._ But one’s evidence might support a self-defeating judgment, and fail to support a self-verifying one. This paper explains how it can be rational to defy one’s evidence if judgment is construed as a mental performance or act, akin to inner assertion. The explanation comes at significant cost, however. Instead of causing or constituting beliefs, judgments turn out to (...) be mere epiphenomena, and self-verification and self-defeat lack the broader philosophical import often claimed for them.

An action is agentially perfect if and only if, if a person tries to perform it, they succeed, and, if a person performs it, they try to. We argue that trying itself is agentially perfect: if a person tries to try to do something, they try to do it; and, if a person tries to do something, they try to try to do it. We show how this claim sheds new light on questions about basic action, the logical structure of (...) intentional action, and the notion of "options" in decision theory. On the way to these central ideas, we argue that a person can try to do something even if they believe it is impossible that they will succeed, that a person can try to do something even if they do not want to succeed, and that a person can try to do something even if they do not intend to succeed.

Daniel Waxman (2022a) argues that the thesis, recently advanced in Rosenkranz 2021, that one has propositional justification for φ, if and only if one is in no position to rule out that one is in a position to know φ, has clear counter examples. However, Waxman makes controversial assumptions about the notion of being in a position to know that I should and coherently can reject. On the alternative construal of the notion open to me, Waxman’s strategy to produce counterexamples (...) founders. However, this line of response has repercussions for two further theses I defend, viz. that propositional justification and its absence each are luminous. It is shown what more needs to be argued in order to avert a corresponding threat to the latter. (shrink)

William P. Alston argues in “Expressing” (1965) that there is no important difference between expressing a feeling in language and asserting that one has that feeling. My aims in this paper are (1) to show that Alston's arguments ought to have led him to a different conclusion—that “asserting” and “expressing” individuate speech acts at different levels of analysis (the illocutionary and the locutionary, respectively)—and (2) to argue that this conclusion can solve a problem facing contemporary analyses of expressing: the “no (...) show tell” problem, or the problem of accounting for utterances that report feelings truly without expressing them. Alston's paper made an important contribution 50 years ago, and a reimagining of it can make another important contribution today. (shrink)

_Framing effects_ concern the having of different attitudes towards logically or necessarily equivalent contents. Framing is of crucial importance for cognitive science, behavioral economics, decision theory, and the social sciences at large. We model a typical kind of framing, grounded in (i) the structural distinction between beliefs activated in working memory and beliefs left inactive in long term memory, and (ii) the topic- or subject matter-sensitivity of belief: a feature of propositional attitudes which is attracting growing research attention. We introduce (...) a class of models featuring (i) and (ii) to represent, and reason about, agents whose belief states can be subject to framing effects. We axiomatize a logic which we prove to be sound and complete with respect to the class. (shrink)

Suppose you assert a proposition p that you falsely believe to be false with the intention to deceive your audience. The standard view has it that you lied. This paper argues against orthodoxy: deceptive lying requires that p be in actual fact false, in addition to your intention to deceive by means of untruthfully asserting that p. We proceed as follows. First, an argument is developed for such falsity condition as the non-psychological component of lying. The problem with the standard (...) view, we profess, is exactly that lying is a purely psychological relation between disbelief, assertion, and intention. Then, by scrutinising familiar cases, we revisit the alleged intuitive support for the existence of true lies. It turns out these intuitions can be explained away once we reflect on the characteristic deceptive hallmarks that are associated with the distinction between lying and botched attempts at lying. Finally, we examine the morality of lying in the light of said falsity condition. The resultant view emphasises our moral sensitivity to the practical consequences of acts of lying, while still accommodating those moral considerations that pertain exclusively to the psychological components of lying.

What is it to base a belief on reasons? Existing attempts to give an account of the basing relation encounter a dilemma: either one appeals to some kind of neutral process that does not adequately reflect the way basing is a content‐sensitive first‐personal activity, or one appeals to linking or bridge principles that over‐intellectualize and threaten regress. We explain why this dilemma arises, and diagnose the commitments that are key obstacles to providing a satisfactory account. We explain why they should (...) be rejected anyway, and then offer a new, knowledge‐first virtue epistemological theory of the basing relation that shows how we can substantially theorize about mental processes without these commitments. The resulting view plausibly captures the way in which basing is an inherently mental and content‐sensitive process. (shrink)

This paper presents a counterexample to the principle that all epistemic reasons for doxastic attitudes towards p are provided by evidence concerning p. I begin by motivating and clarifying the principle and the associated picture of epistemic reasons, including the notion of evidence concerning a proposition, which comprises both first- and second-order evidence. I then introduce the counterexample from incoherent doxastic attitudes by presenting three example cases. In each case, the fact that the subject’s doxastic attitudes are incoherent is an (...) epistemic reason to suspend, which is not provided by evidence. I argue that this incoherence fact is a reason for the subject to take a step back and reassess her evidence for her conflicting attitudes, and thus a reason to suspend all of them. Suspending judgment enables the subject to revise attitudes where appropriate and thus (typically) to arrive at a set of coherent and well-supported attitudes. I then address a dilemma for my proposal and, in conclusion, briefly suggest a picture of epistemic reasons on which they are to be understood against the background of the subject’s virtuous intellectual conduct.

The thesis that knowledge is a factive mental state plays a central role in knowledge-first epistemology, but accepting this thesis requires also accepting an unusually severe version of externalism about the mind. On this strong attitude externalism, whether S is in the mental state of knowledge can and often will rapidly change in virtue of changes in external states of reality with which S has no causal contact. It is commonly thought that this externalism requirement originates in the factivity of (...) knowledge. However, despite a number of recent defenses of non-factive accounts of knowledge, epistemology has yet to consider whether a non-factive approach might produce a version of the mental state thesis that can avoid strong externalism. Here I do just that, exploring how three different proposals for weakening factivity might be adapted to theories of knowledge as a non-factive mental state. Contrary to what we might expect, however, none of these proposals are compatible with anything close to attitude internalism about knowledge—or even a substantially weaker externalism. All told, the widespread view that wraps up the severe externalism required for knowledge to be a mental state in factivity is mistaken. Knowledge’s external-world connection runs far deeper than the factivity constraint. (shrink)

Our universe features a harmonious match between laws and states: applying its laws to its states generates other states. This is a striking fact. Matters might have been otherwise. The universe might have been stillborn in a state unengaged by its laws. The problem of nomological harmony is that of explaining the noted striking fact. After introducing and developing this problem, we canvass candidate solutions and identify some of their virtues and vices. Candidate solutions invoke the likes of a designer, (...) axiarchic meta-laws, multiverses, essential causal powers, and Humean laws. (shrink)

Perception can provide us with a privileged source of evidence about the external world – evidence that makes it rational to believe things about the world. In Reasons First, Mark Schroeder offers a new view on how perception does so. The central motivation behind Schroeder’s account is to offer an answer to what evidence perception equips us with according to which it is what he calls world-implicating but non-factive, and thereby to glean some of the key advantages of both externalism (...) and internalism, respectively. He answers this motivation by developing a more specific view that he calls the Apparent Factive Attitude view, which pairs an answer to what evidence is provided by a perceptual experience with an answer to why having that perceptual experience provides you with that evidence. In this paper we advance two interconnected problems for Schroeder’s Apparent Factive Attitude view. A traditional intuitive judgment that often motivates internalists is the idea that internal duplicates must necessarily be equally rational in whatever beliefs they have. Schroeder’s arguments rely on a weaker claim - that people who are both internal and historical external duplicates but differ only in the veridicality of a single perceptual experience must be equally rational in whatever beliefs they have. In this way he preserves what he argues to be a more compelling internalist intuition. But our arguments will show that Schroeder’s view is committed to denying an even more compelling internalist intuition yet - that internal duplicates must have the same phenomenology. (shrink)

The Reliability Challenge to moral non-naturalism has received substantial attention recently in the literature on moral epistemology. While the popularity of this particular challenge is a recent development, the challenge has a long history, as the form of this challenge can be traced back to a skeptical challenge in the philosophy of mathematics raised by Paul Benacerraf. The current Reliability Challenge is widely regarded as the most sophisticated way to develop this skeptical line of thinking, making the Reliability Challenge the (...) strongest epistemic challenge to normative nonnaturalism. In this paper, I argue that the innovations that have occurred since Benacerraf’s statement of the challenge are misconceived and confused in a number of ways. The Reliability Challenge is not the most potent epistemic challenge to moral non-naturalism. The most potent challenge comes from the fact that there is a causal condition on knowledge – or, more precisely, a becaual condition – that non-natural moral facts cannot satisfy. (shrink)

We face reality presented with the data of conscious experience and nothing else. The project of early modern philosophy was to build a complete theory of the world from this starting point, with no cheating. Crucial to this starting point is the data of conscious sensory experience – sense data. Attempts to avoid this project often argue that the very idea of sense data is confused. But the sense-data way of talking, the sense-data language, can be freed from every blemish (...) using ideas from contemporary metaontology. We can adopt a sense-data framework that vindicates the traditional claims of sense-data theories and leads to plausible theories of perception and color. We can, we should, and in a sense, we must. Yet when we do, we face the traditional problem of external world skepticism, head-on. The real challenge of skepticism is forced upon us; it cannot honestly be avoided using externalist tricks, burden of proof shifting, or other razzle dazzle. But the challenge can be met: we are rational to posit the external world as the best explanation of the many synchronic and diachronic patterns over our sense-data. This paper argues for all of these points and ends with a plea for analytic empiricism – a traditional sense-data version of empiricism that uses all of the tools of analytic philosophy while avoiding the more questionable doctrines of the Vienna Circle (phenomenalism, verificationism). Analytic empiricism is our last best hope for completing the great philosophical project of early modern philosophy. (shrink)

We argue that knowledge is not the norm of belief given that ‘I believe’ is used to hedge. We explore the consequences of this argument for the normative relationship between belief and assertion.

Some physical theories predict that almost all brains in the universe are Boltzmann brains, i.e. short-lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis for rejecting these theories. But the putatively unacceptable consequences of this prediction follow only given certain philosophical assumptions. This paper develops a strategy for shielding physical theorizing from the threat of Boltzmann (...) brains. The strategy appeals to a form of phenomenal externalism about the physical basis of consciousness. Given that form of phenomenal externalism, the proliferation of Boltzmann brains turns out to be benign. While the strategy faces a psychophysical fine-tuning problem, it both alleviates cosmological fine-tuning concerns that attend physics-based solutions to Boltzmann brain problems and pays explanatory dividends in connection with time’s arrow.

According to the sensitivity account of knowledge, if one knows that p, then (roughly) were p false, one would not believe that p. One important issue regarding sensitivity is whether or not it preserves inductive knowledge. Critics including Jonathan Vogel, Ernest Sosa, and Duncan Pritchard argue that it does not. Proponents including Kevin Wallbridge insist that it does. In this paper, I first draw attention to an often-neglected distinction between two different versions of sensitivity—a distinction that has important implications for (...) the debate regarding inductive knowledge. In particular, I distinguish between the sensitivity principle originally defended by Robert Nozick and another version that has been the focus of many recent discussions. With the distinction in place, it is shown that a sensitivity theorist cannot preserve inductive knowledge while being unscathed. For neither account can simultaneously preserve inductive knowledge while properly handling the Gettier problem. Overall, sensitivity theorists are in trouble. (shrink)

Reductive Evidentialism seeks to explain away all structural requirements of rationality – including norms of logical coherence – in terms of substantive norms of rationality, i.e., responsiveness to evidence. While this view constitutes a novel take on the source of the normativity of logic, I argue that it faces serious difficulties. My argument, in a nutshell, is that, on the assumption that individuals with the same evidence can have different rational responses (interpersonal permissivism), the view lacks the resources to maintain (...) its central tenant that an individual’s body of evidence cannot make it rationally permissible for the individual to believe logical inconsistencies (intrapersonal non-permissivism). (shrink)

According to a widely discussed view, knowledge plays a significant normative role in action: It is epistemically rational to treat p as your reason for action if and only if you know that p. As many philosophers have observed, however, this view clashes with the claim that knowledge is moderate and stable. For, granting that claim, there will be high stakes cases in which knowledge seems insufficient. To deal with such cases, some philosophers embracing the knowledge norm combine three independently (...) plausible claims. First, they say that no non-trivial condition is luminous; second, they say that doing something while not being in a position to know that that is appropriate is bad (in high stakes cases); third, they say that in the high stakes cases in question, the subject knows but fails to be in a position to know that she knows (Williamson Philos Q 55:213–235, 2005). This paper argues that this account can overcome the main objections already raised in the literature, but that it still faces the apparently insurmountable challenge of providing a natural and helpful way of substantiating the second claim.

Reasoning from inconclusive evidence, or ‘induction’, is central to science and any applications we make of it. For that reason alone it demands the attention of philosophers of science. This Element explores the prospects of using probability theory to provide an inductive logic, a framework for representing evidential support. Constraints on the ideal evaluation of hypotheses suggest that overall support for a hypothesis is represented by its probability in light of the total evidence, and incremental support, or confirmation, indicated by (...) an increased probability given the evidence than otherwise. This proposal is shown to have the capacity to reconstruct many canons of the scientific method and inductive inference. Along the way, significant objections are discussed, such as the challenge from inductive scepticism and the objection that the probabilistic approach makes evidential support arbitrary. (shrink)

We are witnessing a certain tendency in epistemology to account for the anti-luck intuition in terms of risk. I.e., instead of the traditional anti-luck diagnosis of Gettier cases and fake barn cases, a new anti-risk diagnosis seems to be preferable by many. My goal in this paper is twofold: first, I contribute to motivate that drift; and second, I defend that we ought to partially resist it. An anti-risk diagnosis is valid and preferable for fake barn cases, but we still (...) need an anti-luck diagnosis for classic Gettier cases. The paper thus defends the Solomon-like result that we need both concepts—epistemic luck and epistemic risk—to deal with all the cases where knowledge is undermined. (shrink)

Standard models in epistemic game theory make strong assumptions about agents’ knowledge of their own beliefs. Agents are typically assumed to be introspectively omniscient: if an agent believes an event with probability p, she is certain that she believes it with probability p. This paper investigates the extent to which this assumption can be relaxed while preserving some standard epistemic results. Geanakoplos (1989) claims to provide an Agreement Theorem using the “truth” axiom, together with the property of balancedness, a significant (...) relaxation of introspective omniscience. I provide an example which shows that Geanakoplos’s statement is incorrect. I then introduce a new property, local balancedness, which allows us both to correct Geanakoplos’s result, and to extend it to cases where the truth axiom may fail. I exploit this general Agreement Theorem to provide novel epistemic conditions for correlated and Nash equilibrium, both of which relax the assumption of introspective omniscience. In all three cases, the results are also extended to infinite state spaces. (This is Chapter 5 of my 2014 Oxford DPhil (PhD) thesis.). (shrink)

I advocate scepticism about epistemic blame; the view that we have good reason to think there is no distinctively epistemic form of blame. Epistemologists often find it useful to draw a distinction between blameless and blameworthy norm violation. In recent years, this has led several writers to develop theories of ‘epistemic blame.’ I present two challenges against the very idea of epistemic blame. First, everything that is supposedly done by epistemic blame is done by epistemic evaluation, at least according to (...) a prominent view about the social role of epistemic evaluation. Parsimony considerations count against introducing an idle mechanism that does the same work as an existing one. Second, no current theory of epistemic blame includes a plausible account of the force of epistemic blame or the practices that could express it. I conclude that we should give up the notion of epistemic blame. (shrink)

Intellectual courage requires acting to promote epistemic goods despite significant risk of harm. Courage is distinguished from recklessness and cowardice because the expected epistemic benefit of a courageous action outweighs (in some sense) the threatened harm. Sometimes, however, inquirers pursue theories that are not best supported by their current evidence. For these inquirers, the expected epistemic benefit of their actions cannot be explained by appeal to their evidence alone. The probability of pursuing the true theory cannot contribute enough to the (...) expected epistemic benefit for the action to count as courageous rather than reckless. Thus, there must be some other epistemic consideration which favors their action, besides evidence for their theory. I argue that the proper account of intellectual courage requires recognition of inquisitive reasons: a distinct category of epistemic reasons which concern successful inquiry. This category includes reasons to think a theory itself is promising, e.g., that the theory suggests potentially fruitful new research. It also includes social epistemic reasons, e.g., that pursuing a theory will improve the distribution of cognitive labor. Inquisitive reasons help explain why researchers who pursue improbable theories count as intellectually courageous, rather than reckless. The expected epistemic benefit of an action is partially determined by the inquisitive reasons in its favor. On my account, intellectually courageous inquiry requires acting in a way that is sensitive to inquisitive reasons. (shrink)
