Intellectual progress involves forming a more accurate picture of the world. But it also figuring out which concepts to use for theorizing about the world. Bayesian epistemology has had much to say about the former aspect of our cognitive lives, but little if at all about the latter. I outline a framework for formulating questions about conceptual change in a broadly Bayesian framework. By enriching the resources of Epistemic Utility Theory with a more expansive conception of epistemic value, I offer (...) a picture of our cognitive economy on which adopting new conceptual tools can sometimes be epistemically rational.

One reasons not just in beliefs, but also in intentions, preferences, and other attitudes. For instance, one forms preferences from preferences, or intentions from beliefs and preferences. Formal logic has proved useful for modelling reasoning in beliefs -- a process of forming beliefs from beliefs. Can logic also model reasoning in multiple attitudes? We identify principled obstacles. Logic can model reasoning about one's attitudes -- a process of discovering attitudes -- but not reasoning in attitudes -- a process of forming (...) attitudes. Beliefs are special attitudes in that logic can model both reasoning about beliefs and reasoning in beliefs, namely as entailment between beliefs or entailment between belief contents, respectively. This makes beliefs the privileged target of logic as applied to psychology. (shrink)

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis’s project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is vulnerable. We pose (...) a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made. (shrink)

Decision theory requires agents to assign probabilities to states of the world and utilities to the possible outcomes of different actions. When agents commit to having the probabilities and/or utilities in a decision problem defined by objective features of the world, they may find themselves unable to decide which actions maximize expected utility. Decision theory has long recognized that work-around strategies are available in special cases; this is where dominance reasoning, minimax, and maximin play a role. Here we describe a (...) different work around, wherein a rational decision about one decision problem can be reached by “interpolating” information from another problem that the agent believes has already been rationally solved.

Bayes nets are a powerful tool for researchers in statistics and artificial intelligence. This chapter demonstrates that they are also of much use for philosophers and psychologists interested in (Bayesian) rationality. To do so, we outline the general methodology of Bayes nets modeling in rationality research and illustrate it with several examples from the philosophy and psychology of reasoning and argumentation. Along the way, we discuss the normative foundations of Bayes nets modeling and address some of the methodological problems it (...) raises. (shrink)

Permissivism is the thesis that, for some body of evidence and a proposition p, there is more than one rational doxastic attitude any agent with that evidence can take toward p. Proponents of uniqueness deny permissivism, maintaining that every body of evidence always determines a single rational doxastic attitude. In this paper, we explore the debate between permissivism and uniqueness about evidence, outlining some of the major arguments on each side. We then consider how permissivism can be understood as an (...) underdetermination thesis, and show how this moves the debate forward in fruitful ways: in distinguishing between different types of permissivism, in dispelling classic objections to permissivism, and in shedding light on the relationship between permissivism and evidentialism.

Morality is intrapersonally permissive: cases abound in which an agent has more than one morally permitted option. In contrast, there is a dearth of cases in which an agent has more than one epistemically permitted response to her evidence. Given the structural parallels between morality and epistemology, why do sources of moral permissiveness fail to have parallel permissive effects in the epistemic domain? This asymmetry between morality and epistemology cries out for explanation. The paper's task is to offer an answer (...) to that call. We explain the asymmetry by tracing moral permissiveness to two factors to which rationality is morally but not epistemically sensitive. (shrink)

Cognitivists about practical reason hold that we can explain why certain wide-scope requirements of practical rationality are true by appealing to certain epistemic requirements. Extant discussions of cognitivism focus solely on two claims. The first is the claim that intentions involve beliefs. The second is that whenever your intentions are incoherent in certain ways, you will be epistemically irrational. Even if the cognitivist successfully defends these claims, she still needs to show that they entail certain practical requirements. That is, she (...) has to show that the epistemic requirements explain the practical requirements. In this paper I argue that it is not plausible that the epistemic requirements explain the practical requirements. This shows that the cognitivists' project will fail even if we grant their controversial views about the relationship between the practical and epistemic. (shrink)

This book explores the nature and significance of Pyrrhonism, the most prominent and influential form of skepticism in Western philosophy. Not only did it play an important part in the philosophical scene of the Hellenistic and Imperial age, but it also had a tremendous impact on Renaissance and modern philosophy and continues to be a topic of lively discussion among both scholars of ancient philosophy and epistemologists. The focus and inspiration of the book is the brand of Pyrrhonism expounded in (...) the extant works of Sextus Empiricus. Its aim is twofold: to offer a critical interpretation of some of the central aspects of Sextus’s skeptical outlook and to examine certain debates in contemporary philosophy from a neo-Pyrrhonian perspective. The first part explores the aim of skeptical inquiry, the defining features of Pyrrhonian argumentation, the epistemic challenge posed by the Modes of Agrippa, and the Pyrrhonist’s stance on the requirements of rationality. The second part focuses on present-day discussions of the epistemic significance of disagreement, the limits of self-knowledge, and the nature of rationality. The book will appeal to researchers and graduate students interested in skepticism. (shrink)

Psychologists and philosophers have argued that the capacity for perseverance or “grit” depends both on willpower and on a kind of epistemic resilience. But can a form of hopefulness in one’s future success also constitute a source of grit? I argue that substantial practical hopefulness, as a hope to bring about a desired outcome through exercises of one’s agency, can serve as a distinctive ground for the capacity for perseverance. Gritty agents’ “practical hope” centrally involves an attention-fuelled, risk-inclined weighting of (...) two competing concerns over action: when facing the decision of whether to persevere, hopeful gritty agents prioritize the aim of choosing a course of action which might go very well over that of choosing a course of action which is very likely to go fairly well. By relying on the notion of a “risk-inclined attentional pattern” as a dimension of gritty agents’ practical hope, we can explain that form of hope’s contribution to their motivation and practical rationality, especially on a risk-weighted expected utility framework. The upshot is a more pluralistic view of the sources of grit. (shrink)

It's plausible to think that we're rationally required to follow our total evidence. It's also plausible to think that there are coherence requirements on rationality. It's also plausible to think that higher-order evidence can be misleading. Several epistemologists have recognized the puzzle these claims generate, and the puzzle seems to have only startling and unattractive solutions that involve the rejection of intuitive principles. Yet Alex Worsnip (Philosophy and Phenomenological Research, forthcoming) has recently argued that this puzzle has a tidy, attractive, (...) and independently motivated solution that involves rejecting the claim that we're rationally required to follow our total evidence. In what follows I argue that this solution fails to solve the fundamental problem for rationality. (shrink)

A number of authors have defended permissivism by appealing to rational supererogation, the thought that some doxastic states might be rationally permissible even though there are other, more rational beliefs available. If this is correct, then there are situations that allow for multiple rational doxastic responses, even if some of those responses are rationally suboptimal. In this paper, I will argue that this is the wrong approach to defending permissivism—there are no doxastic states that are rationally supererogatory. By the lights (...) of contemporary linguistics, ‘rational’ is an absolute gradable adjective, and as such, can only be applied to things that satisfy the top of the scale of rationality. For this reason, it is not possible to believe what is rational while also failing to believe what is rationally optimal. (shrink)

This paper offers a new account of how structural rationality, or coherence, is normative. The central challenge to the normativity of coherence – which I term the problem of “making space” for the normativity of coherence – is this: if considerations of coherence matter normatively, it is not clear how we ought to take account of them in our deliberation. Coherence considerations don’t seem to show up in reasoning about what to believe, intend, desire, hope, fear, and so on; moreover, (...) they seem awkward to take account of alongside more “substantive” considerations about the merits of such attitudes. I aim here to solve this problem, and in so doing to offer the aforementioned new account of how coherence is normative. On the view I defend, which I call the Reasons-to-Structure-Deliberation model, considerations of coherence constitute reasons for structuring deliberation in certain ways: more particularly, to treat incoherent combinations of attitudes as off-limits, and so to focus one’s deliberation on choosing between the coherent combinations. (shrink)

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

Extreme Permissivism is the view that a body of evidence could rationally permit both the attitude of belief and disbelief towards a proposition. This paper puts forward a new argument against Extreme Permissivism, which improves on a similar style of argument due to Roger White (2005, 2014). White’s argument is built around the principle that the support relation between evidence and a hypothesis is objective: so that if evidence E makes it rational for an agent to believe a hypothesis H, (...) then E makes it rational to believe H, for all agents. In this paper, I construct a new argument against Extreme Permissivism that appeals to a logically weaker, less demanding view about evidential support, Relational Objectivity: whether a body of evidence E is more likely if H is true than if H is false is an objective matter and does not depend on how any agent interprets the relationship between E and H. Relational Objectivity is solely concerned with the conditional probabilities called likelihoods and does not put substantive constraints on an agent’s prior and posterior credences. For this reason, the presented argument avoids the standard permissivist criticism levelled against White’s argument. (shrink)

A characterization of epistemic rationality, or epistemic justification, is typically taken to require a process of conceptual clarification, and is seen as comprising the core of a theory of (epistemic) rationality. I propose to explicate the concept of rationality. -/- It is essential, I argue, that the normativity of rationality, and the purpose, or goal, for which the particular theory of rationality is being proposed, is taken into account when explicating the concept of rationality. My position thus amounts to an (...) instrumentalist position about theories of epistemic rationality. Since there are different purposes, or goals, for which theories of rationality are proposed, the method of explication leaves room for different characterizations of rationality. I focus on two such (kinds of) purposes: first, the purpose of guiding the formation (or maintenance) of doxastic states and, second, the purpose of assessing (the formation or maintenance of) doxastic states. I conclude by outlining a pluralistic picture concerning rationality. (shrink)

The slogan that rationality is about responding to reasons has a turbulent history: once taken for granted; then widely rejected; now enjoying a resurgence. The slogan is made harder to assess by an ever-increasing plethora of distinctions pertaining to reasons and rationality. Here we are occupied with two such distinctions: that between subjective and objective reasons, and that between structural rationality (a.k.a. coherence) and substantive rationality (a.k.a. reasonableness). Our paper has two main aims. The first is to defend dualism about (...) rationality – the view that affirms a deep distinction between structural and substantive rationality – against its monistic competitors. The second aim is to answer the question: with the two distinctions drawn, what becomes of the slogan that rationality is about responding to reasons? We’ll argue that structural rationality cannot be identified with responsiveness to any kind of reasons. As for substantive rationality, we join others in thinking that the most promising reasons-responsiveness account of substantive rationality will involve an “evidence-relative” understanding of reasons. But we also pose a challenge for making this idea precise – a challenge that ultimately calls into question the fundamentality of the notion of a reason even with respect to the analysis of substantive rationality.

Radical moral encroachment is the view that belief itself is morally evaluable, and that some moral properties of belief itself make a difference to epistemic rationality. To date, almost all proponents of radical moral encroachment hold to an asymmetry thesis: the moral encroaches on rational belief, but not on rational credence. In this paper, we argue against the asymmetry thesis; we show that, insofar as one accepts the most prominent arguments for radical moral encroachment on belief, one should likewise accept (...) radical moral encroachment on credence. We outline and reject potential attempts to establish a basis for asymmetry between the attitude types. Then, we explore the merits and demerits of the two available responses to our symmetry claim: (i) embracing moral encroachment on credence and (ii) denying moral encroachment on belief. (shrink)

In this paper, I propose a Husserlian account of perceptual confidence, and argue for perceptual confidence by appeal to the self-justification of perceptual experiences. Perceptual confidence is the intriguing view, recently developed by John Morrison, that there are not just doxastic confidences but also perceptual confidences, i.e., confidences as aspect of perceptual experience, enabling us to account, e.g., for the increasing confidence with which we experience an approaching human figure, while telling ourselves, as the viewing distance diminishes, “It looks like (...) this just could be Isaac”, “It looks like this is probably Isaac”, “It looks like this is almost certainly Isaac”. I first present my Husserlian account with a focus on the notion of fulfillment, and the idea that the contents of perceptual experience are fulfillment conditions. I then show that this account can be complemented by PC. Finally, I develop a focus on the idea of perceptual self-justification, diverting the perceptual confidence debate from its pre-eminent concern with the relations between perceptual and doxastic confidences, and present an argument to the effect that there are perceptual confidences.

ABSTRACTTimothy Williamson recently argued that the notion of epistemic rationality is ambiguous between a Content-oriented schema and a Disposition-oriented schema. I argue that the Disposition-oriented schema suggested by Williamson is not faithful to the main idea behind it and that it should be replaced with the Disposition-Manifestation schema. This replacement suffices for avoiding Williamson's ambiguity thesis.

Hope is often seen as at once valuable and dangerous: it can fuel our motivation in the face of challenges, but can also distract us from reality and lead us to irrationality. How can we learn to “hope well,” and what does “hoping well” involve? Contemporary philosophers disagree on such normative questions about hope and also on how to define hope as a mental state. This article explores recent philosophical debates surrounding the concept of hope and the norms governing hope. (...) It also underlies hope's significance for the philosophy of emotion and the ethics of interpersonal relations. (shrink)

Is epistemic inconsistency a mere symptom of having violated other requirements of rationality—notably, reasons-responsiveness requirements? Or is inconsistency irrational on its own? This question has important implications for the debate on the normativity of epistemic rationality. In this paper, I defend a new account of the explanatory role of the requirement of epistemic consistency. Roughly, I will argue that, in cases where an epistemically rational agent is permitted to believe P and also permitted to disbelieve P, the consistency requirement plays (...) a distinct explanatory role. I will also argue that such a type of permissiveness is a live possibility when it comes to rational epistemic standards. (shrink)

Gerhard Ernst tries to clarify the nature of rationality. He does this by distinguishing two fundamentally different kinds of rationality: rationality in the “adjustment-sense” and rationality in the “evaluation-sense.” A person is rational in the adjustment-sense if her mental states are well adjusted to each other, i.e. if her beliefs, emotions and intentions fit together (in a sense Ernst explains); a person is rational in the evaluation-sense if she has evaluative beliefs which are adequate on the basis of her non-evaluative (...) beliefs. Our “rational response system,” as Ernst calls it, is concerned with keeping our mind unified by adjusting our mental states to each other and with evaluating what we believe. On the basis of the distinction between rationality in the adjustment-sense and rationality in the evaluation-sense one can understand what is right about the view that rationality consists in responding adequately to reasons and what is right about the view that rationality consists in being consistent (broadly understood).

There are at least two threads in our thought and talk about rationality, both practical and theoretical. In one sense, to be rational is to respond correctly to the reasons one has. Call this substantive rationality. In another sense, to be rational is to be coherent, or to have the right structural relations hold between one’s mental states, independently of whether those attitudes are justified. Call this structural rationality. According to the standard view, structural rationality is associated with a distinctive (...) set of requirements that mandate or prohibit certain combinations of attitudes, and it’s in virtue of violating these requirements that incoherent agents are irrational. I think the standard view is mistaken. The goal of this paper is to explain why, and to motivate an alternative account: rather than corresponding to a set of law-like requirements, structural rationality should be seen as corresponding to a distinctive kind of pro tanto rational pressure—i.e. something that comes in degrees, having both magnitude and direction. Something similar is standardly assumed to be true of substantive rationality. On the resulting picture, each dimension of rational evaluation is associated with a distinct kind of rational pressure—substantive rationality with (what I call) justificatory pressure and structural rationality with attitudinal pressure. The former is generated by one’s reasons while the latter is generated by one’s attitudes. Requirements turn out to be at best a footnote in the theory of rationality. (shrink)

A popular objection to theistic commitment involves the idea that faith is irrational. Specifically, some seem to put forth something like the following argument: (P1) Everyone (or almost everyone) who has faith is epistemically irrational, (P2) All theistic believers have faith, thus (C) All (or most) theistic believers are epistemically irrational. In this paper, I argue that this line of reasoning fails. I do so by considering a number of candidates for what faith might be. I argue that, for each (...) candidate, either (P1) is false or (P2) is false. Then, I make two positive suggestions for how faith can be epistemically rational but nonetheless have a unique relationship to evidence: one, that Jamesian self-justifying attitudes describe a distinctive kind of faith in oneself and others, and two, that faith is not solely based on empirical evidence.

Sometimes epistemologists theorize about belief, a tripartite attitude on which one can believe, withhold belief, or disbelieve a proposition. In other cases, epistemologists theorize about credence, a fine-grained attitude that represents one’s subjective probability or confidence level toward a proposition. How do these two attitudes relate to each other? This article explores the relationship between belief and credence in two categories: descriptive and normative. It then explains the broader significance of the belief-credence connection and concludes with general lessons from the (...) debate thus far. (shrink)

The strong law of large numbers and considerations concerning additional information strongly suggest that Beauty upon awakening has probability 1/3 to be in a heads-awakening but should still believe the probability that the coin landed heads in the Sunday toss to be 1/2. The problem is that she is in a heads-awakening if and only if the coin landed heads. So, how can she rationally assign different probabilities or credences to propositions she knows imply each other? This is the problem (...) I address in this article. I suggest that ‘p whenever q and vice versa’ may be consistent with p and q having different probabilities if one of them refers to a sample space containing ordinary possible worlds and the other to a sample space containing centred possible worlds, because such spaces may fail to combine into one composite probability space and, as a consequence, ‘whenever’ may not be well defined; such is the main contribution of this article. 1The Sleeping Beauty Game2Groisman’s and Peter Lewis’s Approaches3Discussing Beauty’s Credences4The Principle of Equivalence's Failure5Making Sense of the Principle of Equivalence's Failure6Elga’s and Lewis’s Approaches7ConclusionAppendix.

Es mi afirmación que la tabla de intencionalidad (racionalidad, mente, pensamiento, lenguaje, personalidad, etc.) que presenta prominentemente aquí describe más o menos con precisión, o al menos sirve como heurística para, cómo pensamos y nos comportamos, y por lo tanto no abarca simplemente filosofía y psicología, sino todo lo demás (historia, literatura, matemáticas, política, etc.). Tenga en cuenta especialmente que la intencionalidad y racionalidad como yo (junto con Searle, Wittgenstein y otros) lo veo, incluye tanto el Sistema Linguístico deliberativo consciente (...) 2 como las acciones o reflejos inconscientes automatizados del Sistema 1 automatizado. -/- Proporciono una encuesta crítica de algunos de los principales hallazgos de dos de los estudiantes más eminentes de comportamiento de los tiempos modernos, Ludwig Wittgenstein y John Searle, sobre la estructura lógica de la intencionalidad (mente, lenguaje, comportamiento), tomando como punto de partida el descubrimiento fundamental de Wittgenstein -que todos los problemas verdaderamente "filosóficos" son los mismos—confusiones sobre cómo usar el lenguaje en un contexto particular, y por lo tanto todas las soluciones son las mismas— mirando cómo se puede utilizar el lenguaje en el contexto en cuestión para que sus condiciones de verdad (Condiciones de Satisfacción o COS) son claras. El problema básico es que uno puede decir cualquier cosa, pero no se puede significar (indicar COS claro para) cualquier expresión arbitraria y significado sólo es posible en un contexto muy específico. Analizo varios escritos por y sobre ellos desde la perspectiva moderna de los dos sistemas de pensamiento (popularizados como 'pensar rápido, pensar lento'), empleando una nueva tabla de intencionalidad y nueva nomenclatura de sistemas duales. Demuestro que esta es una heurística poderosa para describir el comportamiento. -/- Por lo tanto, todo comportamiento está íntimamente conectado si uno toma el punto de vista correcto. La Ilusión Fenomenológica (olvido a nuestro Sistema automatizado 1) es universal y se extiende no sólo a lo largo de la filosofía, sino a lo largo de la vida. Estoy seguro de que Chomsky, Obama, Zuckerberg y el Papa serían incrédulos si se les dijera que sufren del mismo problema que Hegel, Husserl y Heidegger, (o que difieren sólo en grado de los adictos a las drogas y el sexo en estar motivados por la estimulación de sus cortices frontales por la entrega de dopamina (y más de 100 otros productos químicos) a través del tegmentum ventral y el núcleo accumbens),pero es claramente cierto.

It seems that epistemically rational agents should avoid incoherent combinations of beliefs and should respond correctly to their epistemic reasons. However, some situations seem to indicate that such requirements cannot be simultaneously satisfied. In such contexts, assuming that there is no unsolvable dilemma of epistemic rationality, either (i) it could be rational that one’s higher-order attitudes do not align with one’s first-order attitudes or (ii) requirements such as responding correctly to epistemic reasons that agents have are not genuine rationality requirements. (...) This result doesn’t square well with plausible theoretical assumptions concerning epistemic rationality. So, how do we solve this puzzle? In this paper, I will suggest that an agent can always reason from infallible higher-order reasons. This provides a partial solution to the above puzzle. (shrink)

Belief-credence dualism is the view that we have both beliefs and credences and neither attitude is reducible to the other. Pragmatic encroachment is the view that practical stakes can affect the epistemic rationality of states like knowledge or justified belief. In this paper, I argue that dualism offers a unique explanation of pragmatic encroachment cases. First, I explain pragmatic encroachment and what motivates it. Then, I explain dualism and outline a particular argument for dualism. Finally, I show how dualism can (...) explain the intuitions that underlie pragmatic encroachment. My basic proposal is that in high-stakes cases, it is not that one cannot rationally believe that p; instead, one ought not to rely on one's belief that p. One should rather rely on one's credence in p. I conclude that we need not commit ourselves to pragmatic encroachment in order to explain the intuitiveness of the cases that motivate it. (shrink)

Belief is a familiar attitude: taking something to be the case or regarding it as true. But we are more confident in some of our beliefs than in others. For this reason, many epistemologists appeal to a second attitude, called credence, similar to a degree of confidence. This raises the question: how do belief and credence relate to each other? On a belief-first view, beliefs are more fundamental and credences are a species of beliefs, e.g. beliefs about probabilities. On a (...) credence-first view, credences are more fundamental and beliefs are a species of credence, e.g. credence above some threshold. In this thesis, I develop and defend a third view that I call belief-credence dualism. On this view, belief and credence are independent, equally fundamental attitudes, and neither reduces to the other. I begin by motivating the project: why should we care about the relationship between belief and credence? I argue it has broad implications for many debates in epistemology and beyond. Then, I defend dualism, arguing that it can explain features of our mental lives that a credence-first view and a belief-first view cannot. I also argue that dualism has attractive, interesting implications when applied to the pragmatic encroachment debate. Finally, I explore implications of dualism, both for the nature of evidence and how faith might go beyond the evidence but nonetheless be epistemically rational. I conclude that the human mind is, in some ways, complex, but we should be happy with this conclusion also long as each mental state we posit has a clear role to play. (shrink)

La présente étude a deux objectifs. Le premier est d’examiner les différentes formulations de l’objection de l’ἀπραξία telle qu’elle fut soulevée contre le scepticisme académicien et le pyrrhonisme, ainsi que les réponses à cette objection proposées par Arcésilas et Sextus Empiricus. Le second objectif consiste à évaluer la force de la version de l’objection de l’ἀπραξία selon laquelle le sceptique ne peut réaliser les actions rationnelles propres à l’être humain.

Academic inquiry, in devoting itself primarily to the pursuit of knowledge, is profoundly and damagingly irrational, in a wholesale, structural fashion, when judged from the standpoint of helping to promote human welfare. Judged from this standpoint, academic inquiry devoted to the pursuit of knowledge violates three of the four most elementary rules of rational problem-solving conceivable. Above all, it fails to give intellectual priority to the tasks of (1) articulating problems of living, including global problems, and (2) proposing and critically (...) assessing possible solutions – possible social actions. This gross, structural irrationality of academic inquiry stems from blunders of the 18th century French Enlightenment. The philosophes had the brilliant idea of learning from scientific progress how to achieve social progress towards an enlightened world, but in implementing this idea they made three disastrous blunders. They got the nature of the progress-achieving methods of science wrong; they failed to generalize these methods properly; and most disastrously, they applied these methods to acquiring knowledge about society, and not directly to solving social problems. These blunders are still inherent in academia today, with dire consequences for the state of the world. All this has been pointed out prominently many times since 1976, but has been ignored.

Intentional explanation, according to Elster, seeks to elucidate an action by showing that it was intentionally conducted, in order to bring about certain goals . Intentional actions furthermore, are rational actions: they imply that agents establish a connection between the goals they target and the means that are appropriate to reach them, by way of different beliefs about the means, the goals and the environment. But how should we understand intentional actions in the light of philosophical research on emotions, rationality, (...) and normativity? This question is the departure point of this article. Various philosophers have analyzed the relationships between rationality and emotion, those between emotion and normativity, and those between emotion and intentional action. Nonetheless, their theses are scattered and do not offer an integrative view on how rationality, normativity and emotions work from the standpoint of intentional explanation. By using de Sousa’s distinction between the epistemic and the strategic modes of rationality as a theoretical framework, this article proposes therefore to remedy this deficit by unifying these philosophical insights with the goal of elaborating a theory of intentional explanation which brings together rationality, normativity and emotions.

In recent years, permissivism—the claim that a body of evidence can rationalize more than one response—has enjoyed somewhat of a revival. But it is once again being threatened, this time by a host of new and interesting arguments that, at their core, are challenging the permissivist to explain why rationality matters. A version of the challenge that I am especially interested in is this: if permissivism is true, why should we expect the rational credences to be more accurate than the (...) irrational ones? My aim is to turn this challenge on its head and argue that, actually, those who deny permissivism will have a harder time responding to such a challenge than those who accept it. (shrink)

ABSTRACTWhat conditions must be satisfied if a group is to count as having a justified belief? Jennifer Lackey has recently argued that any adequate account of group justification must be sensitive to both the evidence actually possessed by enough of a group's operative members as well as the evidence those members should have possessed. I first draw attention to a range of objections to Lackey's specific view of group justification and a range of concrete case intuitions any plausible view of (...) group justification must explain. I then offer an alternative view of group justification where the basic idea is that group justification is a matter of groups responsibly responding to their total evidence. This view both avoids the problems facing Lackey's account and also explains the relevant concrete case intuitions. (shrink)

What’s wrong with begging the question? Some philosophers believe that question-begging arguments are inevitably fallacious and that their fallaciousness stems from a shared “formal” deficiency. In contrast, some philosophers, like Robinson deny that begging the question is fallacious at all. And others characterize begging the question as an “informal” fallacy of reasoning that can only be understood with the aid of epistemic notions. Sorensen joins this last camp by offering a powerful argument against both Robinson’s skepticism and fully formal approaches (...) to the phenomenon. According to Sorensen’s view, question-begging is fallacious because it compromises the rationality of the question-beggar’s position. Though his argument forces Robinson into a peculiar dialectical position, it does little to elucidate the reasons why Robinson’s position is unstable and it fails to embody Sorensen’s own conception of rationally persuasive argumentation. I utilize this conception to show how Robinson is left with no easily identifiable grounds on which to deny the fallaciousness of begging the question. By advancing the dialectic between Sorensen and Robinson, I aim to show that our argumentative practices must take the perspectives of others seriously, whether or not those perspectives are rational.

Helen Beebee (2018) defends a view of the aims of philosophy she calls ‘equilibrism’. Equilibrism denies that philosophy aims at knowledge and maintains that the collective aim of philosophy is ‘to find what equilibria there are that can withstand examination’ (Beebee 2018, p. 3). In this note, I probe equilibrism by focusing on how disagreement challenges our doxastic commitment to our own philosophical theories. Call this the Commitment Challenge. I argue that the Commitment Challenge comes in three varieties and that (...) endorsing equilibrism provides us with an answer to one of them only. (shrink)

It seems natural to think of an unwilling addict as having a pattern of preferences that she does not endorse—preferences that, in some sense, she does not ‘identify’ with. Following Frankfurt (1971), Jeffrey (1974) proposed a way of modeling those features of an agent’s preferences by appealing to preferences among preferences.Th„e addict’s preferences are preferences she does not prefer to have. I argue that this modeling suggestion will not do, for it follows from plausible assumptions that a minimally rational agent (...) must prefer those first-order preferences she actually has. I close by considering two different but related ways to think about the initial phenomenon. (shrink)

Epistemic instrumentalists face a puzzle. In brief, the puzzle is that if the reason there is to believe in accord with the evidence depends, as the instrumentalist says it does, on agents’ idiosyncratic interests, then there is no reason to expect that this reason is universal. Here, I identify and explain two strategies instrumentalists have used to try and solve this puzzle. I then argue that we should find these strategies wanting. Faced with the failure of these strategies, I articulate (...) a heretofore neglected solution on behalf of instrumentalism. (shrink)

There are two different kinds of enkratic principles for belief: evidential enkratic principles and normative enkratic principles. It’s frequently taken for granted that there’s not an important difference between them. But evidential enkratic principles are undermined by considerations that gain no traction at all against their normative counterparts. The idea that such an asymmetry exists between evidential and normative enkratic principles is surprising all on its own. It is also something that calls out for explanation. Similarly, the considerations that undermine (...) evidential enkratic principles also undermine certain narrow-scope evidential principles. This too generates explanatory questions. I show how a knowledge-first view of rationality can easily address these explanatory questions. Thus we have one more reason to put knowledge first in epistemology. (shrink)

Despite their success in describing and predicting cognitive behavior, the plausibility of so-called ‘rational explanations’ is often contested on the grounds of computational intractability. Several cognitive scientists have argued that such intractability is an orthogonal pseudoproblem, however, since rational explanations account for the ‘why’ of cognition but are agnostic about the ‘how’. Their central premise is that humans do not actually perform the rational calculations posited by their models, but only act as if they do. Whether or not the problem (...) of intractability is solved by recourse to ‘as if’ explanations critically depends, inter alia, on the semantics of the ‘as if’ connective. We examine the five most sensible explications in the literature, and conclude that none of them circumvents the problem. As a result, rational ‘as if’ explanations must obey the minimal computational constraint of tractability. (shrink)
