The purpose of this essay is to explore, and clarify, some key features in Aquinas’ account of the virtue of temperance, with an eye to answering some common objections raised against a positive evaluation of temperance. In particular, I consider three features of Aquinas’ understanding of temperance: First, the role of the rational mean in temperance; second, the role of rightly ordered passions in temperance; and third, the ‘despotic’ control of reason over the passions in temperance. Along the way I (...) consider three common objections to Aquinas’ account of temperance: the objection that temperance can be misused for evil, the objection that temperance devalues effort, and the objection that temperance devalues strong passions and thereby implicitly devalues the goodness of sexuality. In responding to these objections on behalf of Aquinas, I take the opportunity to clarify and slightly extend Aquinas’ account of temperance. (shrink)

A cursory glance at the list of Nobel Laureates for Economics is sufficient to confirm Stanovich’s description of the project to evaluate human rationality as seminal. Herbert Simon, Reinhard Selten, John Nash, Daniel Kahneman, and others, were awarded their prizes less for their work in economics, per se, than for their work on rationality, as such. Although philosophical works have for millennia attempted to describe, explicate and evaluate individual and collective aspects of rationality, new impetus was brought (...) to this endeavor over the last century as mathematical logic along with the social and behavioral sciences emerged. Yet more recently, over the last several decades, propelled by the emergence of artificial intelligence, cognitive science, evolutionary psychology, neuropsychology, and related fields, even more sophisticated approaches to the study of rationality have emerged.

Our article deals with Aristotle’s account of the sphere of temperance in the Nicomachean Ethics. The goal is to provide a detailed analysis of NE III.10 in order to identify the difficulties this chapter presents us with and to introduce and discuss the interpretations set forth by the secondary literature. Of special interest to us are Aristotle’s intense dialogue with Plato; the difficulty in understanding touch as the most common of the senses and Aristotle’s severe judgment of the pleasures of (...) the sphere of temperance. In short, Aristotle seems to set out from platonic thesis and notions only to distance himself from them by introducing his own, associating temperance with the most common of the senses, namely, the sense of touch. This association is not based, as it could seem primafacie, on a merely empirical observation but on the assumption that touch is the most fundamental and necessary sense for humans and animals alike. Temperance, therefore, as the excellence in the relation with the most fundamental and necessary of the senses, seems to be a pre-condition for rational action. From this Aristotle derives the etymology of the term, as the one who preserves practical reason. This hypothesis would explain why Aristotle seems to engage in apotreptic language to characterize the lack of temperance, that is, the vice of intemperance – something we do not find the in the account of any other virtue and vice.

This article is devoted to define and characterize ‘Science’ as a discipline by the fundamental principles of scientific investigation. In particular, we propose and argue that ‘Science’ be defined by a set of principles / criteria which underlies scientific- investigation. We argue that this set must include the following principles: (1) Rationality, (2) Objectivity (3) Universality, (4) Internal Consistency, (5) Uniqueness, (6) Reproducibility, (7) The Principle of Falsification, (8) Simplicity and Elegance and (9) Experimental Observation and Verification. We elaborate, (...) through illustrative examples, the justification of the above set of criteria. `Scientific temper’ essentially means the cultivation of these principles, as attitudes / value-system adopted as “ways of life”. We discuss the relevance of the inculcation of scientific temper in the modern context. Finally, the scope and limitations of the scientific method are highlighted and an attempt is made to dispel several misconceptions and myths associated with Science and scientists. (shrink)

In the attempt of defending an interpretation of David Hume's moral and political philosophy connected to classical utilitarianism, intervenes in a key way the so called problem of the " Sensitive Knave " raised by this author at the end of his more utilitarian work, the Enquiry Concerning the Principles of Morals. According to the classic interpretation of this fragment, the utilitarian rationality in politics would clash with morality turning useless the latter. Therefore, in the political area the defense (...) of a moral utilitarianism would be an auto contradictory task. In order to show that, first, Hume does not say anything similar to this and second, that even indicates the way of overcoming this apparent contradiction between morality and rationality, we analyze briefly the arguments from which there comes basically this "anti-utilitarian" standard interpretation, and we defend an interpretation of the humean discussion on the problem of the supposed conflict between morality and rationality, or of rational incentives for immoral behavior, which allows to explain better Hume's position on this problem. Finally, we propose an instance of overcoming the contradiction morality/ rationality by a rule adjusted utilitarianism centered on the idea of the "progressive development of artificial institutions of reinforcement of morality", that Hume himself would suggest in other places in which he approaches the topic of the apparent contradiction between "morality" and "knavery". We propose also possible lines of future development of this idea, between them its use to clarify the relation of David Hume's thought with certain forms of contemporary liberalism. (shrink)

Plato’s attitude towards drunkenness (μέθη) is surprisingly positive in the Laws, especially as compared to his negative treatment of intoxication in the Republic. In the Republic, Plato maintains that intoxication causes cowardice and intemperance (3.398e-399e, 3.403e, and 9.571c-573b), while in the Laws, Plato holds that it can produce courage and temperance (1.635b, 1.645d-650a, and 2.665c-672d). This raises the question: Did Plato change his mind, and if he did, why? Ultimately, this paper answers affirmatively and argues that this marks a substantive (...) shift in Plato’s attitude towards anti-rational desires. More precisely, this paper argues that in the Republic, Plato holds that anti-rational desires are always detrimental to health and virtue, while in the Laws, Plato maintains that anti-rational desires can be instrumental to health and virtue.

Recent philosophical work has praised the reward structure of science, while recent empirical work has shown that many scientific results may not be reproducible. I argue that the reward structure of science incentivizes scientists to focus on speed and impact at the expense of the reproducibility of their work, thus contributing to the so-called reproducibility crisis. I use a rational choice model to identify a set of sufficient conditions for this problem to arise, and I argue that these conditions plausibly (...) apply to a wide range of research situations. Currently proposed solutions will not fully address this problem. Philosophical commentators should temper their optimism about the reward structure of science. (shrink)

Whatever may be said about contemporary feminists’ evaluation of Descartes’ role in the history of feminism, Mary Astell herself believed that Descartes’ philosophy held tremendous promise for women. His urging all people to eschew the tyranny of custom and authority in order to uncover the knowledge that could be found in each one of our unsexed souls potentially offered women a great deal of intellectual and personal freedom and power. Certainly Astell often read Descartes in this way, and Astell herself (...) has been interpreted as a feminist – indeed, as the first English feminist. But a close look at Astell’s and Descartes’ theories of reason, and the role of authority in knowledge formation as well as in their philosophies of education, show that there are subtle yet crucial divergences in their thought – divergences which force us to temper our evaluation of Astell as a feminist. -/- My first task is to evaluate Astell’s views on custom and authority in knowledge formation and education by comparing her ideas with those of Descartes. While it is true that Astell seems to share Descartes’ wariness of custom and authority, a careful reading of her work shows that the wariness extends only as far as the tyranny of custom over individual intellectual development. It does not extend to a wariness about social and institutional customs and authority (including, perhaps most crucially, the institution of marriage as we see in her Reflection on Marriage). The reason for this is that Astell’s driving goal is to help women to come to know God’s plan for women – both in their roles as human and in their roles as women. According to Astell, while it is true that, as individuals, women must develop their rational capacities to the fullest in order to honor God and his plan for women as human, as members of social institutions, including the institution of marriage, women must subordinate themselves to men, including their husbands, in this case so as to honor God and his plan for women as women. Once we understand the theological underpinnings of her equivocal reaction to authority and custom, we can see that Astell may be considered a feminist in a very tempered way. -/- My second task is to use these initial conclusions to re-read her proposal for single-sexed education that we find in A Serious Proposal to the Ladies. It is true that Astell encourages women to join single-sexed educational institutions for the unique and empowering friendships that women can develop in such institutions. Still, my argument continues, the development of such friendships is not entirely an end in itself. Rather, Astell encourages women to develop such friendships such that they can re-enter the broader world armed with the tools that will help them endure burdensome features of the lives that await them in the world, including their lives as subordinated wives –burdens that Astell does not, in principle, challenge.

Una interpretación aristotélica del concepto de desarrollo humano propone como fin último del desarrollo la eudaimonía o felicidad, esto es, la plena realización de la capacidad eudemónica en el alma humana. Para esto se requiere del desarrollo de sus partes racional e irracional, lo que demanda como medios una ética y una dianoética del desarrollo, referidos a los modos de ser de las respectivas partes del alma. La interacción entre ambas partes genera siempre un ciclo virtuoso, existiendo la posibilidad de (...) influencias externas a través de la educación, la costumbre, la economía, la legislación y la política. -/- An Aristotelian approach of the concept of human development proposes eudaimonía or happiness as the ultimate goal of development, that is, the full realization of the eudemonic capacity in the human soul.

The interaction between both parts always generates a virtuous cycle, with the possibility of external influences through education, custom, economics, legislation and politics. (shrink)

Although some Muslim scholars have been affected in their ethical system by ancient Greek philosophers, they have also added some Islamic teachings to it and established a combined ethical system (philosophical and religious). Raghib Isfahani, the author of Al-Dharīʿa, is one of these Muslim scholars whose ethical system in this book should be regarded as a combined Islamic Virtue Ethics. It is the combination of Quranic and Philosophical Virtue Ethics. The general framework of his theory is philosophical adopted from Aristotle's (...) and Plato's Virtue Ethics, however, the content of his theory is completely Islamic and Quranic. One of the significant innovations of Raghib in philosophical Virtue Ethics is adding religious virtues to moral virtues. He added theses four religious virtues: Hidāya (God's guidance), Rushd (God's supplement), Tasdīd (God's giving strong will to individuals) and Taʾyīd (God's assistance) to Plato's four ethical virtues (wisdom, temperance, courage and justice). He has called them Tufīqī virtues. According to Raghib, there is no way to obtain virtues but by God's guidance and supplement. By inspiration from Quran, he divided justice into absolute and conditional one. This innovation help us in reconciling Muʿtazilites and as Ashʿarites dispute in being moral goodness and badness rational or religious. (shrink)

The idea of epistemic temperance is introduced and explicated through a discussion of Plato's understanding of it. A variety of psychological and epistemic phenomena are presented which arise due to epistemic intemperance, or the inappropriate influence of conations on cognition. Two cases familiar to philosophers, self-deception and racial prejudice, are discussed as the result of epistemic intemperance though they are not typically seen as having a common cause. Finally, epistemic temperance is distinguished from epistemic justice, as these have been conflated.

Traditional neo-Aristotelian accounts hold that temperance and continence are distinct character traits that are distinguished by the extent to which their bearers experience motivational conflict. In this paper, I formulate two pairs of necessary conditions—which, collectively, I call the conformity thesis—that articulate this distinction. Then, drawing on work in contemporary social and personality psychology, I argue that the conformity thesis is false. Being highly self-controlled is the best, psychologically realistic candidate for continence. However, our best evidence suggests that highly self-controlled/continent (...) people do not experience more or stronger desires that conflict with their evaluative judgments than others, and they are not particularly good at directly resisting these desires. In this way, actual continent people exhibit motivational harmony that is more similar to the traditional picture of temperance. On the other hand, they achieve this harmony because they are able to effectively employ indirect strategies for handling motivational conflict. These strategies are correctly associated with continence. Recognizing that temperance and continence are overlapping character traits puts us in a better position to understand, and design interventions to improve, the neuropsychological capacities that enable humans to intelligently manage their desires.

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like attitude, with (...) world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)

This paper assesses the prospects of a pragmatist theory of content. I begin by criticising the theory presented in D.H. Mellor’s essay ‘Successful Semantics’. I then identify problems and lacunae in the pragmatist theory of meaning sketched in Chapter 13 of Dummett’s The Logical Basis of Metaphysics. The prospects are brighter, I contend, for a tempered pragmatism, in which the theory of content is permitted to draw upon irreducible notions of truth and falsity. I sketch the shape of such a (...) theory and illustrate the role of its pragmatist elements by showing how they point towards a promising account of the truth conditions of indicative conditionals. A feature of the account is that it validates Modus Ponens whilst invalidating Modus Tollens. (shrink)

We argue that the aesthetic domain falls inside the scope of rationality, but does so in its own way. Aesthetic judgment is a stance neither on whether a proposition is to be believed nor on whether an action is to be done, but on whether an object is to be appreciated. Aesthetic judgment is simply appreciation. Correlatively, reasons supporting theoretical, practical and aesthetic judgments operate in fundamentally different ways. The irreducibility of the aesthetic domain is due to the fact (...) that aesthetic judgment is a sensory-affective disclosure of, and responsiveness to, merit: it is a feeling that presents an object, and is responsive to it, as worthy of being liked. Aesthetic judgment is thus shown to be, on the hand, first personal and non-transferable; and, on the other hand, a presentation of reality. We thereby capture what is right in both subjectivist and objectivist conceptions of aesthetic judgment. (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)

The paper argues against a widely held synchronic view of emotional rationality. I begin by considering recent philosophical literature on various backward‐looking emotions, such as regret, grief, resentment, and anger. I articulate the general problem these accounts grapple with: a certain diminution in backward‐looking emotions seems fitting while the reasons for these emotions seem to persist. The problem, I argue, rests on the assumption that if the facts that give reason for an emotion remain unchanged, the emotion remains fitting. (...) However, I argue there are rationally self‐consuming attitudes: affective attitudes that become less fitting the longer they endure while the facts that give reason for them persist. A widely held synchronic view of fitting affective attitudes denies that fittingness at a time depends on the agent's attitudes at different times and therefore denies that the fittingness of an affective attitude can depend on its duration. Once we reject the synchronic view, we may see that affective attitudes are often fitting due to the fitting processes of which they are part. These fitting processes explain the fitting diminution of backward‐looking emotions as well as other diachronic aspects of the fittingness of emotions. -/- . (shrink)

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)

Does rationality require logical omniscience? Our best formal theories of rationality imply that it does, but our ordinary evaluations of rationality seem to suggest otherwise. This paper aims to resolve the tension by arguing that our ordinary evaluations of rationality are not only consistent with the thesis that rationality requires logical omniscience, but also provide a compelling rationale for accepting this thesis in the first place. This paper also defends an account of apriori justification for (...) logical beliefs that is designed to explain the rational requirement of logical omniscience. On this account, apriori justification for beliefs about logic has its source in logical facts, rather than psychological facts about experience, reasoning, or understanding. This account has important consequences for the epistemic role of experience in the logical domain. In a slogan, the epistemic role of experience in the apriori domain is not a justifying role, but rather an enabling and disabling role. (shrink)

The demands of rationality are linked both to our subjective normative perspective (given that rationality is a person-level concept) and to objective reasons or favoring relations (given that rationality is non-contingently authoritative for us). In this paper, I propose a new way of reconciling the tension between these two aspects: roughly, what rationality requires of us is having the attitudes that correspond to our take on reasons in the light of our evidence, but only if it (...) is competent. I show how this view can account for structural rationality on the assumption that intentions and beliefs as such involve competent perceptions of downstream reasons, and explore various implications of the account.

What is structural rationality? Specifically, what is the distinctive feature of structural requirements of rationality? Some philosophers have argued, roughly, that the distinctive feature of structural requirements is coherence. But what does coherence mean, exactly? Or, at least, what do structuralists about rationality have in mind when they claim that structural rationality is coherence? This issue matters for making progress in various active debates concerning rationality. In this paper, I analyze three strategies for figuring out (...) what coherence means in the debates on structural rationality. I argue that these strategies face problems. (shrink)

John Broome argues that rationality cannot consist in reasons-responsiveness since rationality supervenes on the mind, while reasons-responsiveness does not supervene on the mind. I here defend this conception of rationality by way of defending the assumption that reasons-responsiveness supervenes on the mind. Given the many advantages of an analysis of rationality in terms of reasons-responsiveness, and in light of independent considerations in favour of the view that reasons-responsiveness supervenes on the mind, we should take seriously the (...) backup view, a hypothesis that explains why reasons-responsiveness supervenes on the mind even though paradigmatic reasons are external facts. I argue that Broome’s objections to the backup view, as well as his more general objection to the thesis that reasons-responsiveness supervenes on the mind, do not succeed. (shrink)

It is now standard to distinguish between two kinds of rationality: substantive rationality, which consists in holding attitudes that are substantively reasonable or justified, and structural rationality, which consists in holding attitudes that fit together in the right ways. What, if anything, unifies these two kinds of rationality? In this paper, I propose that norms of rationality arise because we are epistemically limited beings who cannot directly ensure the correctness of our attitudes. Substantive and structural (...) rationality represent two different ways of manifesting a fundamental commitment to getting things correct, given our epistemic limitations. Correspondingly, substantive and structural irrationality are distinct rational failures. Substantively irrational attitudes involve a failure to live up to the commitments that constitute those attitudes. Structurally irrational combinations of attitudes are constituted by inconsistent commitments, which guarantees that we will fail to live up to at least some of our commitments in holding these attitudes.

This paper proposes a new account of bounded or minimal doxastic rationality (in the sense of Cherniak 1986), based on the notion that beliefs are answers to questions (à la Yalcin 2018). The core idea is that minimally rational beliefs are linked through thematic connections, rather than entailment relations. Consequently, such beliefs are not deductively closed, but they are closed under parthood (where a part is an entailment that answers a smaller question). And instead of avoiding all inconsistency, minimally (...) rational believers only avoid blatant inconsistencies (where some beliefs are blatantly inconsistent when they contradict one another on a particular question). Rather than cohering into a single overall world view, beliefs are more loosely connected in what is best described as a web of questions. This view of minimally rational belief naturally gives rise to an account of deductive inquiry on which deductive reasoning is a matter of posing new questions. (shrink)

This paper is about the connection between rationality and accuracy. I show that one natural picture about how rationality and accuracy are connected emerges if we assume that rational agents are rationally omniscient. I then develop an alternative picture that allows us to relax this assumption, in order to accommodate certain views about higher order evidence.

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically rational in (...) the sense that both are supported by sufficient evidence.

Do people tend to be overconfident? Many think so. They’ve run studies on whether people are calibrated: whether their average confidence in their opinions matches the proportion of those opinions that are true. Under certain conditions, people are systematically ‘over-calibrated’—for example, of the opinions they’re 80% confident in, only 60% are true. From this empirical over-calibration, it’s inferred that people are irrationally overconfident. My question: When and why is this inference warranted? Answering it requires articulating a general connection between being (...) rational and being right—something extant studies have not done. I show how to do so using the notion of deference. This provides a theoretical foundation for calibration research, but also reveals a flaw: the connection between being rational and being right is much weaker than is standardly assumed, since rational people can often be expected to be miscalibrated. Thus we can’t test whether people are overconfident by simply testing whether they are over-calibrated; instead, we must try to predict the rational deviations from calibration, and then compare those predictions to people’s performance. I show how this can be done—and that doing so complicates the interpretation of robust empirical effects. (shrink)

Consequentialists often assume rational monism: the thesis that options are always made rationally permissible by the maximization of the selfsame quantity. This essay argues that consequentialists should reject rational monism and instead accept rational pluralism: the thesis that, on different occasions, options are made rationally permissible by the maximization of different quantities. The essay then develops a systematic form of rational pluralism which, unlike its rivals, is capable of handling both the Newcomb problems that challenge evidential decision theory and the (...) unstable problems that challenge causal decision theory.

Rationalization, in our intended sense of the term, occurs when a person favors a particular conclusion as a result of some factor (such as self-interest) that is of little justificatory epistemic relevance, if that factor then biases the person’s subsequent search for, and assessment of, potential justifications for the conclusion. Empirical evidence suggests that rationalization is common in people’s moral and philosophical thought. We argue that it is likely that the moral and philosophical thought of philosophers and moral psychologists is (...) also pervaded by rationalization. Moreover, although rationalization has some benefits, overall it would be epistemically better if the moral and philosophical reasoning of people, including professional academics, were not as heavily influenced by rationalization as it likely is. We discuss the significance of our arguments for cognitive management and epistemic responsibility. (shrink)

Permissivism about rationality is the view that there is sometimes more than one rational response to a given body of evidence. In this paper I discuss the relationship between permissivism, deference to rationality, and peer disagreement. I begin by arguing that—contrary to popular opinion—permissivism supports at least a moderate version of conciliationism. I then formulate a worry for permissivism. I show that, given a plausible principle of rational deference, permissive rationality seems to become unstable and to collapse (...) into unique rationality. I conclude with a formulation of a way out of this problem on behalf of the permissivist. (shrink)

Suppose that it is rational to choose or intend a course of action if and only if the course of action maximizes some sort of expectation of some sort of value. What sort of value should this definition appeal to? According to an influential neo-Humean view, the answer is “Utility”, where utility is defined as a measure of subjective preference. According to a rival neo-Aristotelian view, the answer is “Choiceworthiness”, where choiceworthiness is an irreducibly normative notion of a course of (...) action that is good in a certain way. The neo-Humean view requires preferences to be measurable by means of a utility function. Various interpretations of what exactly a “preference” is are explored, to see if there is any interpretation that supports the claim that a rational agent’s “preferences” must satisfy the “axioms” that are necessary for them to be measurable in this way. It is argued that the only interpretation that supports the idea that the rational agent’s preferences must meet these axioms interprets “preferences” as a kind of value-judgment. But this turns out to be version of the neo-Aristotelian view, rather than the neo-Humean view. Rational intentions maximize expected choiceworthiness, not expected utility. (shrink)

The approximate number system (ANS) enables organisms to represent the approximate number of items in an observed collection, quickly and independently of natural language. Recently, it has been proposed that the ANS goes beyond representing natural numbers by extracting and representing rational numbers (Clarke & Beck, 2021a). Prior work demonstrates that adults and children discriminate ratios in an approximate and ratio-dependent manner, consistent with the hallmarks of the ANS. Here, we use a well-known “connectedness illusion” to provide evidence that these (...) ratio-dependent ratio discriminations are (a) based on the perceived number of items in seen displays (and not just non-numerical confounds), (b) are not dependent on verbal working memory, or explicit counting routines, and (c) involve representations with a part-whole (or subset-superset) format, like a fraction, rather than a part-part format, like a ratio. These results vindicate key predictions of the hypothesis that the ANS represents rational numbers. (shrink)

Finite agents such as human beings have reasoning and updating processes that are extended in time; consequently, there is always some lag between the point at which we gain new reasons and the point at which our attitudes have fully responded to those reasons. This phenomenon, which I call rational delay, poses a threat to the most common ways of formulating rational requirements on our attitudes, which do not allow rational beings to exhibit such delay. In this paper, I show (...) first how this problem undermines synchronic formulations of rational norms. Then I show how it likewise undermines the most natural diachronic modifications of these norms. Ultimately, I argue that a successful account of rational delay will reject norms that directly govern attitudes or states of mind like belief and intention altogether, in favor of norms that fundamentally concern temporally extended rational processes like deliberation.

Sufferers of eating disorders often hold false beliefs about their own body size. Such beliefs appear to violate norms of rationality, being neither grounded by nor responsive to appropriate forms of evidence. I defend the rationality of these beliefs. I argue that they are in fact supported by appropriate evidence, emanating from proprioceptive misperception of bodily boundaries. This argument has far‐reaching implications for the explanation and treatment of eating disorders, as well as debates over the relationship between (...) class='Hi'>rationality and human psychology.

A theory of rationality is a theory that evaluates instances of reasoning as rational, irrational, or (ir)rational to some degree. Theories can be categorized as rule-based or consequentialist. Rule-based theories say that rational reasoning accords with certain rules (e.g., of logic or probability). Consequentialist theories say that rational reasoning tends to produce good consequences. For instance, the reliabilist takes rationality to be reasoning that tends to produce mostly true beliefs. The pragmatist takes it to be reasoning that tends (...) to produce mostly useful beliefs. This article reviews some of the features and the challenges of rule-based, reliabilist, and pragmatist theories of rationality. (shrink)

Theories of rational decision making often abstract away from computational and other resource limitations faced by real agents. An alternative approach known as resource rationality puts such matters front and center, grounding choice and decision in the rational use of finite resources. Anticipated by earlier work in economics and in computer science, this approach has recently seen rapid development and application in the cognitive sciences. Here, the theory of rationality plays a dual role, both as a framework for (...) normative assessment and as a source of scientific hypotheses about how mental processes in fact work. The latter project, often called rational analysis, depends for its success on a fine-grained characterization of the computational problem facing a decision maker, which may in turn depend on realistic assumptions about what the relevant agent is like. As a consequence, resource rationality involves a delicate, but often fruitful interplay between the normative and the descriptive. (shrink)

This paper explores an initially attractive principle connecting beliefs in general with beliefs about what beliefs are rational. The principle turns out to be violated by intuitively rational beliefs in some situations. The paper lays out some options for reacting to this fact.

We present an abstract model of rationality that focuses on structural properties of attitudes. Rationality requires coherence between your attitudes, such as your beliefs, values, and intentions. We define three 'logical' conditions on attitudes: consistency, completeness, and closedness. They parallel the familiar logical conditions on beliefs, but contrast with standard rationality conditions like preference transitivity. We establish a formal correspondence between our logical conditions and standard rationality conditions. Addressing John Broome's programme 'rationality through reasoning', we (...) formally characterize how you can (not) become more logical by reasoning. Our analysis connects rationality with logic, and enables logical talk about multi-attitude psychology. (shrink)

What should a person do when, through no fault of her own, she ends up believing a false moral theory? Some suggest that she should act against what the false theory recommends; others argue that she should follow her rationally held moral beliefs. While the former view better accords with intuitions about cases, the latter one seems to enjoy a critical advantage: It seems better able to render moral requirements ‘followable’ or ‘action-guiding.’ But this tempting thought proves difficult to justify. (...) Indeed, whether it can be justified turns out to depend importantly on the rational status of epistemic akrasia. Furthermore, it can be argued, from premises all parties to the moral ignorance debate should accept, that rational epistemic akrasia is possible. If the argument proves successful, it follows that a person should sometimes act against her rationally held moral convictions. (shrink)

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic (...) class='Hi'>rationality is sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)

It is clear that beliefs can be assessed both as to their justification and their rationality. What is not as clear, however, is how the rationality and justification of belief relate to one another. Stewart Cohen has stumped for the popular proposal that rationality and justification come to the same thing, that rational beliefs just are justified beliefs, supporting his view by arguing that ‘justified belief’ and ‘rational belief’ are synonymous. In this paper, I will give reason (...) to think that Cohen’s argument is spurious. I will show that ‘rational’ and ‘justified’ occupy two distinct semantic categories – ‘rational’ is an absolute gradable adjective and ‘justified’ is a relative gradable adjective – telling against the thought that ‘rational belief’ and ‘justified belief’ are synonymous. I will then argue that the burden of proof is on those who would equate rationality and justification, making the case that those who hold this prominent position face the difficulty of explaining how rationality and justification come to the same thing even though ‘rational’ and ‘justified’ are not synonymous.

The reasoning view of rational normativity claims that structural rationality is normative for reasoning. Specifically, it claims that structural rationality gives us reasons to structure deliberation in ways that respect the requirements of rationality. This paper critically assesses the reasoning view. It argues that while the reasoning view might succeed in responding to arguments against the normativity of rationality, it is in tension with the motivations for thinking that rationality is normative in the first place. (...) Moreover, proponents of the view do not offer any independent reason for thinking that the view is true. As such, we have no reason to accept the reasoning view. (shrink)

According to epistemological disjunctivism (ED), in paradigmatic cases of perceptual knowledge, a subject, S, has perceptual knowledge that p in virtue of being in possession of reasons for her belief that p which are both factive and reflectively accessible to S. It has been argued that ED is better placed than both knowledge internalism and knowledge externalism to undercut underdetermination-based skepticism. I identify several principles that must be true if ED is to be uniquely placed to attain this goal. After (...) that, I use those principles to formulate a diachronic skeptical argument. This argument yields the counterintuitive conclusion that understanding a global skeptical hypothesis is all it takes for a rational subject to lose all her perceptual knowledge of the world. Next, I show that a popular Austinian move must reject one or another of the principles that underlie ED. I close by delineating a novel strategy that can block the diachronic skeptical argument while preserving all the principles. The key idea is that perceptual knowledge is grounded in primitive, perceptual and recognitional abilities. This view sheds new light on some puzzling features of global skepticism that have been noted by Descartes and Hume, among others. (shrink)

Broome takes the debate on rationality to be concerned with the ordinary use of 'rational'. I argue that this is at best misleading. For the object of current theories of rationality is determined by a specific use of 'rational' that is intimately connected to blame and praise. I call the property it refers to 'rationalityRESP'. This focus on rationalityRESP, I argue, has two significant implications for Broome's critique of theories of rationality as reasons-responsiveness. First, rationalityRESP is plausibly (...) conceived of as a kind of reasons-responsiveness. Secondly, Broome's dispute with internalists about normativity as well as his dispute with externalists about rationality both hinge on questions regarding the concept of responsibility. I conclude that philosophers should integrate discussions about responsibility in their debates about rationality. (shrink)

Rationalization in the sense of biased self-justification is very familiar. It's not cheating because everyone else is doing it too. I didn't report the abuse because it wasn't my place. I understated my income this year because I paid too much in tax last year. I'm only a social smoker, so I won't get cancer. The mental mechanisms subserving rationalization have been studied closely by psychologists. However, when viewed against the backdrop of philosophical accounts of the regulative role of truth (...) in doxastic deliberation , rationalization can look very puzzling. Almost all contemporary philosophers endorse a version of the thesis of deliberative exclusivity—a thinker cannot in full consciousness decide whether to believe that p in a way that issues directly in forming a belief by adducing anything other than considerations that he or she regards as relevant to the truth of p. But, as I argue, rationalization involves the weighing of considerations that the thinker kn.. (shrink)

This paper seeks to elucidate the distinctive nature of the rational impression on its own terms, asking precisely what it means for the Stoics to define logikē phantasia as an impression whose content is expressible in language. I argue first that impression, generically, is direct and reflexive awareness of the world, the way animals get information about their surroundings. Then, that the rational impression, specifically, is inherently conceptual, inferential, and linguistic, i.e. thick with propositional content, the way humans receive incoming (...) information from the world. When we suspend certain contemporary assumptions about propositional content, the textual evidence can be taken at face value to reveal why, for the Stoics, rational impressions are called thoughts (noēseis) and how the Stoics’ novel semantic entities called lekta (roughly, the meanings of our words) depend on rational impressions for their subsistence.

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such (...) challenges, and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

This paper argues that instrumental rationality is more permissive than expected utility theory. The most compelling instrumentalist argument in favour of separability, its core requirement, is that agents with non-separable preferences end up badly off by their own lights in some dynamic choice problems. I argue that once we focus on the question of whether agents’ attitudes to uncertain prospects help define their ends in their own right, or instead only assign instrumental value in virtue of the outcomes they (...) may lead to, we see that the argument must fail. Either attitudes to prospects assign non-instrumental value in their own right, in which case we cannot establish the irrationality of the dynamic choice behaviour of agents with non-separable preferences. Or they don’t, in which case agents with non-separable preferences can avoid the problematic choice behaviour without adopting separable preferences. (shrink)

Closure for justification is the claim that thinkers are justified in believing the logical consequences of their justified beliefs, at least when those consequences are competently deduced. Many have found this principle to be very plausible. Even more attractive is the special case of Closure known as Single-Premise Closure. In this paper, I present a challenge to Single-Premise Closure. The challenge is based on the phenomenon of rational self-doubt – it can be rational to be less than fully confident in (...) one's beliefs and patterns of reasoning. In rough outline, the argument is as follows: Consider a thinker who deduces a conclusion from a justified initial premise via an incredibly long sequence of small competent deductions. Surely, such a thinker should suspect that he has made a mistake somewhere. And surely, given this, he should not believe the conclusion of the deduction even though he has a justified belief in the initial premise. (shrink)
