Alex Worsnip's recent book, Fitting Things Together: Coherence and the Demands of Structural Rationality, provides a sustained, wide-ranging defence of dualism.

Does immorality necessarily involve irrationality? The question is often taken to be among the deepest in moral philosophy. But apparently deep questions sometimes admit of deflationary answers. In this case we can make way for a deflationary answer by appealing to dualism about rationality, according to which there are two fundamentally distinct notions of rationality: structural rationality and substantive rationality. I have defended dualism elsewhere. Here, I’ll argue that it allows us to embrace (...) a sensible – I will not say boring – moderate view about the relationship between immorality and irrationality: roughly, that immorality involves substantive irrationality, but not structural irrationality. I defend this moderate view, and argue that many of the arguments for less moderate views turn either on missing the distinction between substantive and structural rationality, or on misconstruing it.

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)

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)

Dualism about possible worlds says that merely possible worlds aren’t concrete objects, but the actual world is concrete. This view seems to be the natural one for ersatzers about merely possible worlds to take; yet one is hard-pressed to find any defenders of it in contemporary modal metaphysics. The main reason is that Dualism struggles with the issue of how merely possible worlds could have been actual. I explain that there are two different Dualist strategies that (...) can be taken to address the problem. Furthermore, one or other of these strategies should be plausible to anyone who accepts both Existentialism—which tells us that the existence of singular propositions depends on what they directly refer to—and Serious Actualism—which tells us that things must exist in order to instantiate properties. Though it has long been ignored, Dualism is a live option. (shrink)

Much of the literature on the relationship between belief and credence has focused on the reduction question: that is, whether either belief or credence reduces to the other. This debate, while important, only scratches the surface of the belief-credence connection. Even on the anti-reductive dualist view, belief and credence could still be very tightly connected. Here, I explore questions about the belief-credence connection that go beyond reduction. This paper is dedicated to what I call the independence question: just how (...) independent are belief and credence? I look at this question from two angles: a descriptive one (as a psychological matter, how much can belief and credence come apart?) and a normative one (for a rational person, how closely connected are belief and credence?) Ultimately, I suggest that the two attitudes are more independent than one might think. (shrink)

Rationality requires that our mental attitudes exhibit specific patterns of coherence. Do we have reason to comply? 'Prichardian Quietists' regard this question as fundamentally confused: the only reasons to comply with rational requirements are the ones given by the requirements themselves. In this paper, I argue that PQ fails. I proceed by granting that Prichard's own position, from which PQ draws inspiration, is defensible, while identifying three serious problems with the parallel position about rationality. First, as I (...) argue, PQ is not plausibly combined with either the narrow-scope or the wide-scope formulations of rational requirements. Second, PQ implies that the reasons to comply with rational requirements are reasons of the wrong kind. And finally, PQ lacks a crucial component of its explanation, viz. a plausible theory of what constitutes being rationally required to V. (shrink)

Just as Quine and others have argued for a deflationism about the property of truth, Sinan Dogramaci has argued for a deflationism about rationality. Specifically, Dogramaci claims that we have no reason to think that the basic, deductive, epistemic rules we call “rational” have any sort of “unifying property.” A “unifying property” is a property that is necessary, sufficient, and explanatorily illuminating. My goal in this paper is to undermine Dogramaci’s argument for this radical position. I do (...) this by first outlining Dogramaci’s distinctive view on the function of our epistemically evaluative terms. This view, called epistemic communism, has it that the function of terms like “rational” is to support the coordination of our community on a single set of epistemic rules. I offer a reconstruction of Dogramaci’s argument from epistemic communism to deflationism about rationality. I next raise an objection to Dogramaci’s argument: different sets of epistemic rules do not equally support the coordinative function. Dogramaci has a response to this objection, but I argue that this response is less than satisfactory. I illustrate that this response is unsatisfactory by employing work by David Enoch and Joshua Schechter. After pushing my objection to Dogramaci’s argument, I develop, on Dogramaci’s behalf, an objection to my non-deflationary attempt to undermine his argument. In the final section of the paper, I reply to this objection offered on Dogramaci’s behalf and conclude that whether we are epistemic communists or not, we need not accept deflationism. (shrink)

Knowledge-first evidentialism combines the view that it is rational to believe what is supported by one's evidence with the view that one's evidence is what one knows. While there is much to be said for the view, it is widely perceived to fail in the face of cases of reasonable error—particularly extreme ones like new Evil Demon scenarios (Wedgwood, 2002). One reply has been to say that even in such cases what one knows supports the target rational belief (Lord, 201x, (...) this volume). I spell out two versions of the strategy. The direct one uses what one knows as the input to principles of rationality such as conditionalization, dominance avoidance, etc. I argue that it fails in hybrid cases that are Good with respect to one belief and Bad with respect to another. The indirect strategy uses what one knows to determine a body of supported propositions that is in turn the input to principles of rationality. I sketch a simple formal implementation of the indirect strategy and show that it avoids the difficulty. I conclude that the indirect strategy offers the most promising way for knowledge-first evidentialists to deal with the New Evil Demon problem. (shrink)

There is much to admire in John Pittard’s recent book on the epistemology of disagreement. But here we develop one concern about the role that rational insight plays in his project. Pittard develops and defends a view on which a party to peer disagreement can show substantial partiality to his own view, so long as he enjoys even moderate rational insight into the truth of his view or the cogency of his reasoning for his view. Pittard argues that this (...) may happen in ordinary cases of religious disagreement—cases in which it’s a live skeptical possibility that one is misdescribing his insight, or not having insight at all—and therefore one need not be strongly conciliatory even in the face of peer disagreement. Yet Pittard agrees that one should be strongly conciliatory in cases of disagreement involving, e.g., visual perception and dim rational insight, since the sort of fallible, corrigible evidence involved in such cases may be counterbalanced by symmetrical evidence on the part of one’s disagreeing peer. We worry that there’s an inconsistency here. If it’s unreasonable to show partiality to one’s visual experience (or dim rational insight) in cases like “Horse Race” and “Restaurant Check,” it’s likewise unreasonable to show partiality in religious disagreements to one’s moderate rational insight, fallible and corrigible as it is.

In this paper, I present a puzzle about epistemic rationality. It seems plausible that it should be rational to believe a proposition if you have sufficient evidential support for it. It seems plausible that it rationality requires you to conform to the categorical requirements of rationality. It also seems plausible that our first-order attitudes ought to mesh with our higher-order attitudes. It seems unfortunate that we cannot accept all three claims about rationality. I will (...) present three ways of trying to resolve this tension and argue that the best way to do this is to reject the idea that strong evidential support is the stuff rationality is made of. In the course of doing this, I shall argue that there is a special class of propositions about the requirements of rationality that we cannot make rational mistakes about and explain how this can be.

Mental causation, idea that it is us – via our minds – who cause bodily actions is as commonsensical as it is indispensable for our understanding of ourselves as rational agents. Somewhat less uncontroversial, but nonetheless widespread (at least among ordinary people) is the idea that the mind is non-physical, following the intuition that what is physical can neither act nor think nor judge morally. Taken together, and cast into a metaphysical thesis, the two intuitions yield interactive dualism: the (...) view that human persons and their minds are non-physical but can nonetheless interact with their bodies, most notably through their brains. This thesis has two main objectives: first, to defend interactive dualism against objections, and second, to show how it can blend in with a physical world in which laws of nature hold. The first part (chapter 1) consists in a brief motivation of interactive dualism as opposed to non-interactive dualism. I argue that non-interactive, epiphenomenalist dualism sacrifices so many crucial aspects of our human existence that interactive dualism is highly to be preferred to it, barring even stronger counterarguments against the latter. It is those putative counterarguments I address in parts II and III. Part II takes on the philosophical objections from the causal closure of the physical and from causal heterogeneity. The former takes the success of physics and physiology as basis for the doctrine of the causal closure of the physical (CCP). I argue against this that there is not only no convincing argument for CCP, but also that any science-based belief in CCP cannot be epistemically justified. As regards the causal heterogeneity objection, it is ‘weighed and found wanting’, because it relies on unwarranted assumptions about causation. In part III, I examine the objection from energy conservation. It roughly says that if interactive dualism were true, then energy would not be conserved, which physics taught us cannot be the case. My reply is that the underlying conception of energy (and momentum) conservation is wrong-headed and not the one that actual physicists use. Instead of being categorical and global, conservation laws are conditional and local, thereby making natural room for mental interaction. Some dualists, however, have sought to make interactive dualism conservation-friendly, notably by invoking quantum physics; I show that these attempts are unnecessary and create more problems than they solve. Finally, in chapter 9, I turn the tables on non-interactionists by investigating current neurophysiological literature on volitional actions, which, though not addressing the question directly, still encourages the interactive dualist picture more than a non-interactionist one. Part IV is about the interplay between interactive dualism and the laws of nature. The ultimate goal is, if possible, to come up with a theory of the laws of nature that explains the lawlike behavior of nature and at the same time makes room for interaction. I begin by pointing out that the laws of nature are or at least should be what physicalists worry about (chapter 10). I then proceed with a historical survey on the development of the notion of laws of nature (chapter 11) that sheds light on its theistic origin. This is followed by an inquiry into the question how a law of nature could possibly be broken (chapter 12) and a survey of the extant metaphysical theories of the laws of nature with special regard to their receptivity to interaction (chapter 13). Finally, in chapter 14 I develop a theory of the laws of nature both faithful to their divine origin and the possibility of mental interaction: dispositionalist divine decretalism, a synthesis of dispositionalism and Jeffrey Koperski’s divine decretalism.

Within the social sciences, much controversy exists about which status should be ascribed to the rationality assumption that forms the core of rational choice theories. Whilst realists argue that the rationality assumption is an empirical claim which describes real processes that cause individual action, instrumentalists maintain that it amounts to nothing more than an analytically set axiom or ‘as if’ hypothesis which helps in the generation of accurate predictions. In this paper, I argue that this realist-instrumentalist debate (...) about rational choice theory can be overcome once it is realised that the rationality assumption is neither an empirical description nor an ‘as if’ hypothesis, but a normative claim.

As Ebbinghaus (1908) tells us in the opening words of his popular textbook of psychology, “psychology has a long past but only a short history.” In my opinion, there are three foundational moments in the history of psychology and, paradoxically, all three are moments of great advancement in biology. First, in the long past of psychology, psychology did not exist as such but was part of philosophy. It is extremely interesting to understand why it has been necessary, at one point (...) of time in the sixteenth century, to invent this field and to create a signifier – namely “psychology” – separate from philosophy, which enabled the field to distinguish itself from philosophy (Mengal, 2000/2001). In this century of religious violence, bare corpses lay everywhere and progresses in anatomy are major. In 1540, the German religious reformer Philippe Melanchthon publishes a book which comments the De anima of Aristotle and he completes the Aristotelian text with a long treaty of anatomy (Mengal, 2000/2001). On the basis of this new knowledge, Melanchthon attributes functions to the body which were previously reserved for the soul. The brain becomes the principal organ of sensory functions and displaces the heart as the seat of emotional life and of thought. To the Aristotelian position that all living beings, whether plant, animal, or human, to varying degrees possess a soul which organizes the body, Melanchthon opposes a dualistic anthropology which divides the human in body and soul. The two-dimensional “anthropologia” is articulated in “anatomia,” science of body, and “psychologia,” science of the soul. It is this new anthropology that is diffused into the world of the Reformation (Mengal, 2000/2001). The Dutch reformer Snellius (1594), for example, defines the body and the soul by their respective essential property: “The rational soul of man is the thought that, coupled with the body, completes man. (…) The physical things closer to natural bodies that move naturally, have an extension and for that reason occupy a space. (…) The faculty of the rational soul is the mind or will. Thought is the faculty of the soul to discourse and think about things which are and which are not.”1 (Snellius, 1594, pp. 26–27). It is as a philosopher that René Descartes proposes his dualist vision much in line with the reformist opinions. Descartes dissects animals and human cadavers and is familiar with the research on the flow of blood (Fuchs, 2001). He comes to the conclusion that the body is a complex device that is capable of moving without the soul, thus contradicting the Aristotelian doctrine of the soul. The metaphysical order, which states that the body exists by the soul, is broken. (shrink)

Scholars disagree about whether and how Kant manages to avoid dualistic outcomes in the relation between freedom and sensibility within the moral agent. If he does not – if he portrays a moral agent who must judge and act without taking emotions, sentiments, and passions into account – then authors such as Blackburn can rightly argue that Kantian ethics loses sight of the concrete individual, whose sensibility has a fundamental role, taking part in the definition of her specific identity. (...) I argue that this portrait comes from a disputable and incomplete reading of Kant’s works. There is no dualistic outcome in the relation between freedom and sensibility in Kant. My aim is to show that there is a bridge between the rational and the sensible elements within the Kantian agent and that it can be reconstructed by analysing Kant’s works on ethics, aesthetics, and anthropology. Specifically, those elements must be thought of as in accordance, not in opposition, because sensibility is necessary for Kant’s ethics to be effective, both for the agent’s awareness of the moral law and for the agent’s motivation.

A primary goal of this chapter is to highlight neglected epistemic parallels between dualism and physicalism. Both dualist and physicalist arguments employ a combination of empirical data and armchair reflection; both rely on considerations stemming from how we conceptualize certain phenomena; and both aim to establish views that are compatible with scientific results but go well beyond the deliverances of empirical science. -/- I begin the chapter by fleshing out the distinctive commitments of dualism, in a way that (...) illuminates the interplay of epistemic and metaphysical elements within the dualist position. Section 2 outlines two influential arguments for dualism and explains how dualists defend those arguments from key criticisms. Sections 3 and 4 examine the most powerful objections to dualism: that it is inferior to physicalism as regards the theoretical virtue of simplicity, and that it cannot explain mental causation. I show that each of these objections to dualism depends on substantial assumptions that cannot be empirically justified. The objection from mental causation additionally rests on an ambitious assumption about how we conceptualize physical phenomena. Section 5 briefly reviews how epistemic considerations inform arguments on both sides of this debate. (shrink)

My dissertation covers a number of different topics in Kant scholarship, but is driven by one central question: how do our sense-based capacities to perceive, desire, and feel relate to our capacity to reason? I take the answer to this question to be key to understanding much about Kant’s philosophical system. For topics as diverse as the role that sensation plays in practical knowledge, the character of moral motivation, the nature of evil, or Kant’s theory that we are morally (...) required to believe in our immortality and God’s existence, I claim that the correct reading turns on a novel approach to the relation between our rational and sensitive capacities. To properly understand this relation, we must overcome the deeply entrenched thought that Kant inherits his conception of reason from the rationalists, and his conception of sense experience from the empiricists. This would be to adopt a fundamentally dualistic philosophy, on which reason and the senses are independently intelligible and sometimes even diametrically opposed. On Kant’s actual view, our capacities to perceive, feel, and desire are metaphysically interdependent with and thus not intelligible in isolation from our capacity to reason. Developing the details of this more unified position leads to satisfying philosophical accounts of a number of controversial issues in Kant scholarship that have suffered under a dualistic framework.

Kant’s pre-1770 philosophy responded to the mind-body problem by applying a theory of “physical influx”. His encounter with Swedenborg’s mysticism, however, left him disillusioned with any dualist solution to Descartes’ problem. One of the major goals of the Critical philosophy was to provide a completely new solution to the mind-body problem. Kant’s new solution is “perspectival” in the sense that all Critical theories are perspectival: it acknowledges a deep truth in both of the controversy’s extremes (i.e., what we might nowadays (...) call eliminative materialism and an absolutely ideal folk psychology), by viewing both as ways of considering the issue, rather than as the only correct approach. Once we take into account its perspectival character, a new way of understanding Kant’s philosophy of mind emerges. The mind is no longer separate from the body, but is a manifestation of it, viewed from another (specifically human, rational) perspective. Kant’s transcendental conditions of knowledge (spatio-temporal intuition, categorial conception, and principled schematization) do not portray the mind as somehow creating the physical world; rather, they imply the opposite, that knowledge of objects is necessarily structured by a set of unconscious assumptions about the physical world. Our pre-conscious (or pre-mental, in Descartes’ sense of “mental”) encounter with an assumed spatio-temporal, causal nexus is entirely physical. A reincarnated Kant’s solution to today’s mind-body problem would be: eliminative materialism is good science; but only the “explanatory idealist” can consistently be an eliminative materialist. Philosophically, multiple perspectives are necessary in order to understand anything we say or do. (shrink)

Espousing non-reductive physicalism, how do we pick out the specific relevant physical notion(s) from physical facts, specifically in relation to phenomenal experience? Beginning with a historical review of Gilbert Ryle’s behaviorism and moving through Hilary Putnam’s machine-state functionalism and Wilfrid Sellars’ inferential framework, up to more contemporaneous computationalist- and cognitivist-functionalism (Gualtiero Piccinini), we survey accounts of mentality that countenance the emergence of mental states vide input- and output-scheme. Ultimately arriving at the conclusion that functionalism cannot account for problems such as (...) no-cognition reports, we see any robust defense of physicalism must appeal to other principles. Thus we move on to the question of emergence, not as it pertains to the hard(er) problem, but to the matter of conceptual externalization of mental properties from physical properties. Accordingly, we navigate Karen Bennett’s compatibilist solution to the exclusion argument against mental causation for the non-reductive physicalist position, according to which the physical effects of mental cases are not overdetermined, demonstrating that this backfires by offering a path for the mind-body interactionist Dualist to claim causal closure by appealing to this same schema. We conclude with a series of conceptual musings regarding rationality which take into account our challenges and findings, querying about whether phenomenal consciousness is a fundamentally private, or socially configured, notion.

This essay is an inquiry into John McDowell’s thinking on ‘subjectivity.’ The project consists in two parts. On the one hand, I will discuss how McDowell understands and responds to the various issues he is tackling; on the other, I will approach relevant issues concerning subjectivity by considering different aspects of it: a subject as a perceiver, knower, thinker, speaker, agent, person and (self-) conscious being in the world. The inquiry begins by identifying and resolving a tension generated by the (...) very idea of ‘rational animal’: human beings are at the same time natural and rational. Later the inquiry proceeds by considering how McDowell’s notion of ‘second nature’ enables us to be human subjects with many faces. By going through the diagnoses and responses of McDowell, two central problems in modern and contemporary philosophy – the narrow conception of nature and the Cartesian inner space model – are identified and repelled. In Episode N I first urge that we should leave room for a certain notion of ‘world.’ I further argue that mentality has many aspects, and to understand those aspects is to understand the many faces of human subject. In Episode Ⅰ the Aristotelian notion of ‘second nature’ is discussed in order to resolve the tension in the very idea of ‘rational animal.’ Later I reply to some worries about this maneuver, including the objection from Crispin Wright. Hans-Georg Gadamer’s distinction between world and environment is introduced and related to McDowell’s thinking. Episode Ⅱ discusses perception and knowledge; McDowell’s main target – the Cartesian inner space – is introduced and criticized. Barry Stroud’s and Simon Blackburn’s positions are evaluated. Later I connect the main theme of Mind and World to the present context; in particular, I discuss McDowell’s invocation of Donald Davidson and Immanuel Kant. And then I discuss a common accusation of idealism, and Robert Brandom’s accusation of ‘residual individualism.’ Episode Ⅲ concentrates on Saul Kripke’s Wittgenstein, arguing that the master thesis behind the rule-following paradox is a version of the inner space model, and that Kripke’s Wittgenstein is not Wittgenstein. Martin Kusch’s objections are answered; Michael Dummett’s demand of reductionism is rebutted. After this, I turn to Davidson’s ‘no language’ claim, and discuss to what extent McDowell agrees with him. In Episode Ⅳ I evaluate objections from Hubert Dreyfus concerning action and agency. I discuss how Dreyfus and Maurice Merleau-Ponty commit ‘the Myth of the Disembodied Intellect’ identified by McDowell. I answer Michael Ayer’s charge of intellectualism in passing. Later I bring in McDowell’s objections to Derek Parfit on personhood and to Davidson on the mind-body relation. In Episode Ⅴ I focus on consciousness and self-consciousness. McDowell applies his argument against Parfit to Kant, but Maximilian de Gaynesford dissents. I reply to his objections on McDowell’s behalf. I further connect this to McDowell’s attacks on the dualism of scheme and content. This leads to my McDowellian rejection to the existence of qualia, and further brings me to the debate between intentionalism and disjunctivism in the context of the argument from illusion. I argue against Tim Crane’s ways of conceiving issues about intentionalism and the argument from illusion. Varieties of disjunctivism are also discussed. In my Epilogue, I express my worry about McDowell’s notion of ‘self-determining subjectivity.’ According to McDowell, human freedom consists in causations in the space of reason, but as Richard Gaskin points out, a satisfying story of it is yet to be provided. I close this essay with some rough ideas about how to fill in the details of the McDowellian picture. (shrink)

Death can be bad for an individual who has died, according to the “deprivation approach,” by depriving that individual of goods. One worry for this account of death’s badness is the Lucretian symmetry argument: since we do not regret having been born later than we could have been born, and since posthumous nonexistence is the mirror image of prenatal nonexistence, we should not regret dying earlier than we could have died. Anthony Brueckner and John Martin Fischer have developed a response (...) to the Lucretian challenge by arguing that it is rational to have asymmetric attitudes toward posthumous and prenatal nonexistence. Recently, Jens Johansson has criticized the Brueckner/Fischer position, claiming that it is irrelevant whether it is actually rational to care about future pleasures but not past pleasures. What matters, according to Johansson, is whether it would be rational for us to care about past pleasures had we come into existence earlier. In this paper, I add to the conversation between Johansson and Brueckner/Fischer by suggesting a way to defend the latter side’s position in a way that has not yet been suggested. I do this by considering a suggestion of Johansson’s for interpreting the Brueckner/Fischer position and by arguing that Johansson’s worry for the position I consider is actually incoherent.

In this paper, I explore anomalous dualism about consciousness, a view that has not previously been explored in any detail. We can classify theories of consciousness along two dimensions: first, a theory might be physicalist or dualist; second, a theory might endorse any of the three following views regarding causal relations between phenomenal properties (properties that characterize states of our consciousness) and physical properties: nomism (the two kinds of property interact through deterministic laws), acausalism (they do not causally (...) interact), and anomalism (they interact but not through deterministic laws). I suggest that a kind of anomalous dualism, nonreductive anomalous panpsychism, promises to offer the best overall answer to two pressing issues for dualist views, the problem of mental causation and the mapping problem (the problem of predicting mind-body associations).

Many contemporary epistemologists take rational inference to be a conscious action performed by the thinker (Boghossian 2014; 2018; Valaris 2014; Malmgren 2018). It is tempting to think that rational evaluability requires responsibility, which in turn requires conscious action. In that case, unconscious cognition involves merely associative or otherwise arational processing. This paper argues instead for deep rationalism: unconscious inference often exhibits the same rational status and richly structured logical character as conscious inference. The central case study is rationalization, in which (...) people shift their attitudes in logically structured, reason-responsive ways in response to evidence of their own incompetence or immorality. These attitude shifts are irrational in a way that reflects on the thinker. Thus rationally evaluable inference extends downward into the unconscious. Many take the sole aim of belief to be truth (Velleman 2000) or knowledge (Williamson 2000), but the prevalence of rationalization suggests that belief updating often aims instead at preserving our positive conceptions of ourselves—that is, belief updating is part of a psychological immune system (Gilbert 2006; Mandelbaum 2019). This paper argues that the psychological immune system comprises a suite of distinct cognitive mechanisms, some (ir)rational and some arational, which are united by a common function of avoiding the maladaptive predomination of negative affect and maintaining stable motivation. Other aspects of the psychological immune system include (i) a domain-general positive bias in evaluative attitudes and (ii) “terror management,” i.e., the systematic strengthening of meaning-conferring beliefs to avoid death anxiety. The multiplicity of processes underlying the psychological immune system point toward an irrational but adaptive function of cognition to keep us motivated in a world rife with negativity and death.

Many economists and philosophers assume that status quo bias is necessarily irrational. I argue that, in some cases, status quo bias is fully rational. I discuss the rationality of status quo bias on both subjective and objective theories of the rationality of preferences. I argue that subjective theories cannot plausibly condemn this bias as irrational. I then discuss one kind of objective theory, which holds that a conservative bias toward existing things of value is rational. This account can (...) fruitfully explain some compelling aspects of common sense morality, and it may justify status quo bias. (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)

This essay is about the relationship between the notions of practical reason, the will, and choice in Kant’s practical philosophy. Although Kant explicitly identifies practical reason and the will, many interpreters argue that he cannot really mean it on the grounds that unless they are distinct, irrational and, especially, immoral action is impossible. Other readers affirm his identification but distinguish the will from choice on the same basis. We argue that proper attention to Kant’s conception of practical reason as (...) a capacity reveals that these distinctions are neither textually grounded nor philosophically necessary. His moral psychology concerns a single capacity, practical reason, which is the will, and whose actualities in this or that individual fall under the title of choice. Practical reason is the will and choice because it is the rational faculty of desire: a rational being’s capacity to be, by means of her representations, the cause of the actuality of their objects. This, we argue, is entailed by his conception of rational action: action not just in accordance with, but in and through the representation of, principles. The possibility of irrational action is explained not by a distinction between capacities but by the finitude, and thereby the fallibility, of human reason. (shrink)

This paper looks at whether it is possible to unify the requirements of rationality with the demands of normative reasons. It might seem impossible to do because one depends upon the agent’s perspective and the other upon features of the situation. Enter Reasons Perspectivism. Reasons perspectivists think they can show that rationality does consist in responding correctly to reasons by placing epistemic constraints on these reasons. They think that if normative reasons are subject to the right epistemic constraints, (...) rational requirements will correspond to the demands generated by normative reasons. While this proposal is prima facie plausible, it cannot ultimately unify reasons and rationality. There is no epistemic constraint that can do what reasons perspectivists would need it to do. Some constraints are too strict. The rest are too slack. This points to a general problem with the reasons-first program. Once we recognize that the agent’s epistemic position helps determine what she should do, we have to reject the idea that the features of the agent’s situation can help determine what we should do. Either rationality crowds out reasons and their demands or the reasons will make unreasonable demands. (shrink)

I argue for the unexceptionality of evidence about what rationality requires. Specifically, I argue that, as for other topics, one’s total evidence can sometimes support false beliefs about this. Despite being prima facie innocuous, a number of philosophers have recently denied this. Some have argued that the facts about what rationality requires are highly dependent on the agent’s situation and change depending on what that situation is like. (Bradley 2019). Others have argued that a particular (...) subset of normative truths, those concerning what epistemic rationality requires, have the special property of being ‘fixed points’—it is impossible to have total evidence that supports false belief about them. (Smithies 2012; Titelbaum 2015). Each of these kinds of exceptionality permits a solution to downstream theoretical problems that arise from the possibility of evidence supporting false belief about requirements of rationality. However, as I argue here, they incur heavy explanatory burdens that we should avoid. (shrink)

The relative efficiency of an action is a central criterion in action control and can be used to predict others’ behavior. Yet, it is unclear when the ability to predict on and reason about the efficiency of others’ actions develops. In three main and two followup studies, 3- to 6-year-old children (n = 242) were confronted with vignettes in which protagonists could take a short (efficient) path or a long path. Children predicted which path the protagonist would take and (...) why the protagonist would take a specific path. The 3-year-olds did not take efficiency into account when making decisions even when there was an explicit goal, the task was simplified and made more salient, and children were questioned after exposure to the agent’s action. Four years is a transition age for rational action prediction, and the 5-year-olds reasoned on the efficiency of actions before relying on them to predict others’ behavior. Results are discussed within a representational redescription account. (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)

Epiphenomenalist dualists hold that certain physical states give rise to non-physical conscious experiences, but that these non-physical experiences are themselves causally inefficacious. Among the most pressing challenges facing epiphenomenalists is the so-called “paradox of phenomenal judgment”, which challenges epiphenomenalism’s ability to account for our knowledge of our own conscious experiences. According to this objection, we lack knowledge of the very thing that epiphenomenalists take physicalists to be unable to explain. By developing an epiphenomenalist theory of subjects and mental states, this (...) paper argues that there is nothing paradoxical or problematic about the epiphenomenalist’s understanding of phenomenal judgments or phenomenal self-knowledge. The appearance of paradox emerges from inconsistently combining (epiphenomenalist) dualism about qualia with a physicalistic conception of subjects of experience. The lesson we should take from this is not that there is anything wrong with epiphenomenalism, but that epiphenomenalist dualists should be “dualists all the way down”—embracing a picture of mind that gives phenomenology a central place, in its understanding of both subjects and their knowledge of their own minds. Epiphenomenalist-friendly accounts of reference and memory are also developed, showing that neither of these issues creates a paradox for the epiphenomenalist. (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)

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.

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)

The empirically documented fact is that people’s preferences are time -biased. The main aim of this paper is to analyse in which sense do time -biases violate the requirements of rationality, as many authors assume. I will demonstrate that contrary to many influential views in psychology, economy and philosophy it is very difficult to find why the bias toward the near violates the requirements rationality. I will also show why the bias toward the future violates the requirements of (...) rationality in a very basic sense. (shrink)

With the growing focus on prevention in medicine, studies of how to describe risk have become increasing important. Recently, some researchers have argued against giving patients “comparative risk information,” such as data about whether their baseline risk of developing a particular disease is above or below average. The concern is that giving patients this information will interfere with their consideration of more relevant data, such as the specific chance of getting the disease (the “personal risk”), the risk reduction the (...) treatment provides, and any possible side effects. I explore this view and the theories of rationality that ground it, and I argue instead that comparative risk information can play a positive role in decision-making. The criticism of disclosing this sort of information to patients, I conclude, rests on a mistakenly narrow account of the goals of prevention and the nature of rational choice in medicine. (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)

Constitutivist approaches to the normativity of rationality have recently come into vogue. Unlike their moral counterparts, however, they have not been confronted with the shmagency objection. In this paper, I challenge them with two versions of the objection based on recent developments in the debate surrounding the normativity of morality. These are shmagency as modal escapability, which is based on taking sophisticated shmagents to be able to modally escape various norms, and shmagency as underdetermination, which is based on taking (...) constitutive norms that allegedly have independent value to be underdetermined by that value. I consider three different kinds of constitutivist theories of the normativity of rationality: first-person-authority views, single-mental-state views, and systems-of-mental-states views. None of the three are able to deal with either of these shmagency objections. There are sophisticated shmagents who escape all these types of constitutivist principles of rationality, so they are modally escapable, and the value of rationality underdetermines all the views. Upshot: constitutivists about structural rationality ought to worry about shmagency. (shrink)

According to Conciliationism, rationality calls for a removal of dissenting opinions – in the end, the disagreement should lead to skepticism toward the disputed proposition for all the involved parties. However, psychological data regarding group inquiry indicates that groups with dissenting members are more successful in their inquiry with respect to the disputed propositions. So, according to the psychological data, rationality calls for preserving dissent – disagreement should be embraced as a great tool for getting at true beliefs. (...) In this paper I analyze this apparent conflict. (shrink)

In ‘The Epistemic Goals of the Humanities’, Stephen Grimm (2024) argues for epistemic continuities between the humanities, on one hand, and the social and natural sciences, on the other. This paper focuses on discontinuities. Drawing inspiration from Svetlana Alexievich’s literary non-fiction, I argue that if a reader is to gain a specific kind of understanding of the actions of the agents who appear in such work, they must engage in a rational evaluation of those agents’ reasons and actions. This epistemic (...) process may yield, not just understanding of another’s action, but a grip on the evaluative distance between the reader and the agents she reads about, together with a greater appreciation of normative matters. These epistemic gains are, I suggest, central to the value of the humanities, and play a key role in its corrective power. (shrink)

What can features of cognitive architecture, e.g. the information encapsulation of certain emotion processing systems, tell us about emotional rationality? de Sousa proposes the following hypothesis: “the role of emotions is to supply the insufficiency of reason by imitating the encapsulation of perceptual modes” (de Sousa 1987: 195). Very roughly, emotion processing can sometimes occur in a way that is insensitive to what an agent already knows, and such processing can assist reasoning by restricting the response-options she considers. (...) This paper aims to provide an exposition and assessment of de Sousa’s hypothesis. I argue information encapsulation is not essential to emotion-driven reasoning, as emotions can determine the relevance of response-options even without being encapsulated. However, I argue encapsulation can still play a role in assisting reasoning by restricting response-options more efficiently, and in a way that ensures which options emotions deem relevant are not overridden by what the agent knows. I end by briefly explaining why this very feature also helps explain how emotions can, on occasion, hinder reasoning. (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 theses of this paper are that: 1. the attempt to found absolute norms on rationality presupposes the availability of a single universal absolute conception of rationality, but no such conception is available; and 2. any conception of rationality which might be available for justifying one's ultimate normative commitments is itself evaluative. “Rationality” itself is a value-laden concept, as are all its philosophical sub-divisions—logic, ethics, aesthetics, axiology, etc. Choosing ultimate value principles under conditions of freedom, enlightenment, (...) and impartiality presupposes that one positively values such things. Rationality is an inescapably evaluative concept, not a value neutral concept. (shrink)

According to a widely held view, rationality demands that the preferences of a person be transitive. The transitivity assumption is an axiom in standard theories of rational choice. It is also prima facie very plausible. I argue here that transitivity is not a necessary condition of rationality; it is a constraint only in some cases. The argument presented here is based on the non-linearity of differential utility functions. This paper has four parts. First, I present an argument against (...) the transitivity assumption (I, II). Second, I discuss some objections; this will also bring out some features of the view defended here, like the essentially comparative nature of choice (III). Then, I discuss certain proposals that promise to avoid my conclusion (IV). Finally, I go into some implications concerning the nature of rational decision making (V). To accept some intransitivities as rational does not make our life easier; it can even lead to hard choices. However, it does not lead to skepticism about rational choice. (shrink)

Conciliationism holds that disagreement of apparent epistemic peers often substantially undermines rational confidence in our opinions. Uniqueness principles say that there is at most one maximally rational doxastic response to any given batch of total evidence. The two views are often thought to be tightly connected. This paper distinguishes two ways of motivating conciliationism, and two ways that conciliationism may be undermined by permissive accounts of rationality. It shows how conciliationism can flourish under certain strongly permissive accounts of (...) class='Hi'>rationality. This occurs when the motivation for conciliationism does not come from taking disagreement as evidence of one's own rational failings. However, divorcing the motive for conciliating from worries about rationality does not remove a feature of conciliationism that some find troubling: that conciliationism can lead to cases of “rational toxicity,” in which the most rational response to one's evidence involves violating some rational ideal.

I advocate Time-Slice Rationality, the thesis that the relationship between two time-slices of the same person is not importantly different, for purposes of rational evaluation, from the relationship between time-slices of distinct persons. The locus of rationality, so to speak, is the time-slice rather than the temporally extended agent. This claim is motivated by consideration of puzzle cases for personal identity over time and by a very moderate form of internalism about rationality. Time-Slice Rationality conflicts (...) with two proposed principles of rationality, Conditionalization and Reflection. Conditionalization is a diachronic norm saying how your current degrees of belief should fit with your old ones, while Reflection is a norm enjoining you to defer to the degrees of belief that you expect to have in the future. But they are independently problematic and should be replaced by improved, time-slice-centric principles. Conditionalization should be replaced by a synchronic norm saying what degrees of belief you ought to have given your current evidence and Reflection should be replaced by a norm which instructs you to defer to the degrees of belief of agents you take to be experts. These replacement principles do all the work that the old principles were supposed to do while avoiding their problems. In this way, Time-Slice Rationality puts the theory of rationality on firmer foundations and yields better norms than alternative, non-time-slice-centric approaches. (shrink)

According to Nicole Oresme (c. 1320–1382), human beings, unlike all other animals, consist of two substances: a thinking substance and a sensing substance. This paper presents and explores the arguments Oresme uses to arrive at this position, which is unusual in medieval philosophical psychology and which at least superficially – though their methods are completely different – resembles what Descartes concluded about the nature of the human soul and body two and a half centuries later. The paper also considers (...) some moments of ambivalence in Oresme’s presentation, as well as unresolved difficulties, several of which have theological as well as philosophical implications.

This paper evaluates an argument according to which many anthropologists commit themselves to Cartesian dualism, when they talk about meanings. This kind of dualism, it is argued, makes it impossible for anthropologists to adequately attend to material artefacts. The argument is very original, but it is also vulnerable to a range of objections.

Here we will argue that Henry Sidgwick’s Dualism of Practical Reason, the paired imperative of being egoistic and/or utilitarian, follows from the epistemic barriers that arise when giving credence to skepticism about the external world, and particularly skepticism about other minds, and skepticism about reincarnation. We will argue that this is true whether we begin with the premises of universal utilitarianism or egoism.
