According to many philosophers, rationality is, at least in part, a matter of one’s attitudes cohering with one another. Theorists who endorse this idea have devoted much attention to formulating various coherence requirements. Surprisingly, they have said very little about what it takes for a set of attitudes to be coherent in general. We articulate and defend a general account on which a set of attitudes is coherent just in case and because it is logically possible for the attitudes to (...) be jointly satisfied in the sense of jointly fitting the world. In addition, we show how the account can help adjudicate debates about how to formulate various rational requirements. (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 entry is composed of three sections. In §1, we survey debates about what structural rationality is, including the emergence of the concept in the contemporary literature, its key characteristics, its relationship to substantive rationality, its paradigm instances, and the questions of whether these instances are unified and, if so, how. In §2, we turn to the debate about structural requirements of rationality – including controversies about whether they are “wide-scope” or “narrow-scope”, synchronic or diachronic, and whether they govern processes (...) or states; as well as examining various forms of skepticism about structural requirements of rationality. In §3, we turn to the debate about the normative significance of structural rationality, surveying central challenges for the view that structural rationality is normatively significant and the theoretical options that arise in light of these challenges.

Kierkegaard's pseudonym Johannes Climacus famously defines faith as a risky “venture” that requires “holding fast” to “objective uncertainty.” Yet puzzlingly, he emphasizes that faith requires resolute conviction and certainty. Moreover, Climacus claims that all beliefs about contingent propositions about the external world “exclude doubt” and “nullify uncertainty,” but also that uncertainty is “continually present” in these very same beliefs. This paper argues that these apparent contradictions can be resolved by interpreting Climacus as a belief‐credence dualist. That is, Climacus holds that (...) beliefs and credences (i.e., degrees of belief) are two irreducibly distinct types of mental states. Beliefs are resolutions that close inquiry, thereby excluding doubt and reflecting subjective certainty by disregarding the possibility of error. Credences, by contrast, reflect assessments of evidential probabilities, thereby encoding a recognition of “objective uncertainty” by acknowledging the possibility of error. In addition to solving a vexing interpretive puzzle and showing how Kierkegaard anticipates contemporary views about the nature of belief and credence, this paper demonstrates that Kierkegaard developed a sophisticated account of the nature of belief, doubt, and certainty that merits serious philosophical consideration.

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 normativity of so-called “coherence” or “structural” requirements of rationality has been hotly debated in recent years. However, relatively little has been said about the nature of structural rationality, or what makes a set of attitudes structurally irrational, if structural rationality is not ultimately a matter of responding correctly to reasons. This paper develops a novel account of incoherence (or structural irrationality), critically examining Alex Worsnip’s recent account. It first argues that Worsnip’s account both over-generates and under-generates incoherent patterns of (...) attitudes, and then proposes an alternative that both avoids these problems and captures a crucial insight behind Worsnip’s account. According to this account, a set of attitudes is incoherent just in case having all of the attitudes in that set is incompatible with reacting to a question in a way that one is, in virtue of having the attitudes, committed to.

In this paper, I offer a novel view of the coherence (or structural) requirements on belief and intention, according to which they are not norms, but rather principles describing how your belief and intention operate. I first argue, on the basis of the unintelligibility of some relevant attitudes-reports, that there are conditions under which you simply do not count as believing or intending unless your beliefs and intentions satisfy the requirements: the conditions under which all of your relevant attitudes are (...) occurrent or activated. I then argue that you are subject to a coherence requirement only if your relevant attitudes are all activated, for you are not necessarily subject to the charge of irrationality in violating a coherence requirement when your attitudes are not all activated. If so, however, you satisfy the coherence requirements whenever you are subject to them, which makes it plausible that the “requirements” should be seen as descriptive principles about belief and intention.

How can we make rational decisions that involve transformative experiences, that is, experiences that can radically change our core preferences? L. A. Paul (2014) has argued that many decisions involving transformative experiences cannot be rational. However, Paul acknowledges that some traumatic events can be transformative experiences, but are nevertheless not an obstacle to rational decision-making. For instance, being attacked by hungry sharks would be a transformative experience, and yet, deciding not to swim with hungry sharks is rational. Paul has tried (...) to explain why decisions involving ‘sharky’ outcomes are an exception to the rule. However, her putative explanation has been criticized by Campbell and Mosquera (2020). In this paper, I offer a different solution to this problem. Roughly, I argue that transformative experiences give rise a problem for rational decision-making only if the decision can lead to satisfying some of our (new) core preferences, but can also frustrate other (new) core preferences. I also argue that agents can partially project what traumatic transformative experiences are like. (shrink)

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view successfully explains what is wrong with certain akratic doxastic states. In this paper I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all (...) of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment and credence. These explanations deploy the notions of knowledge and being in a position to know, instead of the notion of responding properly to the evidence. Finally, I suggest that this picture can be generalized to the realm of practical rationality as well. (shrink)

What is the place of coherence, or structural rationality, in good first-personal deliberation? According to Kolodny (2005), considerations of coherence are irrelevant to good first-personal deliberation. When we deliberate, we should merely care about the reasons or evidence we have for our attitudes. So, considerations of coherence should not show up in deliberation. In response to this argument, Worsnip (2021) argues that considerations of coherence matter for how we structure deliberation. For him, we should treat incoherent combinations of attitudes as (...) off-limits in deliberation. Some important questions are left unanswered by both camps. What do we mean by considerations of coherence “showing up” in first-personal deliberation? How do we interpret the divide between reasons-responsiveness and coherence? How should we interpret cases in which considerations of coherence interact with other norms or requirements? In this paper, I show how Haack’s (1993) crossword puzzle analogy sheds light on these questions. Also, the crossword puzzle analogy allows us to evaluate Kolodny’s objection and identify promising avenues for future research. (shrink)

Structural requirements of rationality prohibit various things, like having inconsistent combinations of attitudes, having means-end incoherent combinations of attitudes, and so on. But what is the distinctive feature of structural requirements of rationality? And do we fall under an obligation to be structurally rational? These issues have been at the heart of significant debates over the past fifteen years. Some philosophers have recently argued that we can unify the structural requirements of rationality by analyzing what is constitutive of our attitudes (...) (Lee, 2020; Worsnip, 2018a). It has also been suggested that, in the course of good first-personal deliberation, agents should treat structurally irrational combinations of attitudes as off-limits (Worsnip, 2021). In this paper, I raise a worry for these two theses concerning structural rationality. Roughly, I argue that some imperfect epistemic agents (like us) can be disposed to have structurally irrational combinations of attitudes. Also, when these imperfect agents deliberate, they should not treat structurally irrational combinations of attitudes as off-limits. Given our imperfections, being structurally irrational can very well be the best option we have. More generally, these observations reveal that structural rationality should not always be theorized independently from more “substantive” norms, like responsiveness to reasons or expected value optimization.

In a narrow sense of ‘disagreement,’ you and I disagree iff we believe inconsistent propositions. But there are numerous cases not covered by this definition that seem to constitute disagreements in a wider sense: disagreements about what to do, disagreements in attitude, disagreements in credence, etc. This wider sense of disagreement plays an important role in metaethics and epistemology. But what is it to disagree in the wider sense? On the view I’ll defend, roughly, you and I disagree in the (...) wide sense iff we hold attitudes that it would be incoherent for a single individual to hold. I’ll argue that this captures the relevant cases, and explore the consequences for metaethical debates between expressivists and contextualists. My view has two broader upshots: that coherence is a theoretically important property, and that an apparently descriptive question—are two subjects disagreeing?—turns on a normative one—are their attitudes jointly incoherent? (shrink)

On an increasingly popular view of rationality, rationality is fundamentally about responding correctly to reasons and there is no independent rational requirement to avoid incoherence: having an incoherent combination of attitudes is irrational not because there is a fundamental requirement of rationality that prohibits it, but rather because you are guaranteed to fail to respond correctly to reasons in having it. This paper argues that any such attempt to explain the irrationality of incoherence in terms of responsiveness to reasons fails. (...) For there is something distinctively irrational about incoherence that is not explained in terms of the guaranteed failure to respond to reasons. Any adequate account of the nature of coherence requirements on belief and intention should take into account the distinctive kind of commitments involved in each type of attitude.

Predicates of personal taste have attracted a great deal of attention from philosophers of language and linguists. In the intricate debates over PPT, arguably the most central consideration has been which analysis of PPT can best account for the possibility of faultless disagreement about matters of personal taste. I argue that two models of such disagreement—the relativist and absolutist models—are empirically inadequate. In their stead, I develop a model of faultless taste disagreement which represents it as involving a novel incompatibility (...) relation between preferences that I call type-noncotenability. This model is available to all parties in the ongoing debates about PPT, but it points up an advantage enjoyed by expressivist accounts of PPT. In closing, I consider four objections against the model that, while failing to fully undermine it, open up promising avenues of inquiry about the nature of disagreement. (shrink)

In this paper, we address a key question that has been central to discussions on rationality: is the concept of rationality normative or merely descriptive? We present the findings of a corpus-linguistic study revealing that people commonly perceive the concept of rationality as normative.

One influential response to apparent higher-order dilemmas implies that agents can rationally both believe p on the basis of their evidence and simultaneously believe that their evidence does not support believing p. This possibility of rational epistemic akrasia seems to call into question the Enkratic Requirement, which prohibits believing a proposition p according to one’s lower-level evidence, while believing that one’s lower-level evidence does not support believing p. In this chapter, we explore two ways to defend the Enkratic Requirement. First, (...) evidentialists about epistemic justification are committed to holding that an ex post (or doxastically) justified belief, as part and parcel of being ex post justified, is accompanied by a corresponding higher-order belief that the first-order belief is supported by the evidence. In a dilemma case, this higher-order belief comes into direct rational conflict with the subject’s other higher-order belief, that her evidence does not support the belief – so the subject has contradictory beliefs. In this way, the so-called ‘level-splitting’ strategy for the claim that being akratic is not per se irrational is called into question. Our second argument for the Enkratic Requirement presupposes normativism about belief and appeals to the conditions of having epistemically permissible beliefs. We sketch an argument starting from an influential view about the normativity of belief: that irrational beliefs are impermissible beliefs. From this claim, together with some widely held as-sumptions about the notion of rationality, we show that agents who display akratic combi-nations of attitudes hold impermissible beliefs. (shrink)

It's often said that it is impossible to respond to non-evidential considerations in belief-formation, at least not directly and consciously. Many philosophers think that this provides grounds for accepting a normative thesis: typically, some kind of evidentialism about reasons for belief, or what one ought to believe. Some also think it supports thinking that evidentialist norms are constitutive of belief. There are a variety of ways in which one might try to support such theses by appeal to the impossibility-claim. In (...) this paper, I put pressure on these various attempts by raising a simple yet overlooked problem for them. In brief, the problem is that it isn't true that one cannot (directly and consciously) respond, in belief-formation to considerations that don't actually constitute (good) evidence for the proposition under consideration; what is true, at most, is that one cannot (directly and consciously) respond, in belief-formation to considerations that one oneself takes to be evidentially irrelevant to that proposition. While this point is obvious once stated, its significance hasn't been appreciated, or so I'll argue. Once we take full account of it, the standard arguments from the impossibility-claim to evidentialism don't go through. (shrink)

To explain why we should be structurally rational – or mentally coherent – is notoriously difficult. Some philosophers argue that the normativity of structural rationality can be explained in terms of substantive rationality, which is a matter of correct response to reason. I argue that the psychological phenomena – positive illusions – are counterexamples to the substantivist approach. Substantivists dismiss the relevance of positive illusions because they accept evidentialism that reason for belief must be evidence. I argue that their evidentialist (...) stance would imply that we are caught in unsolvable dilemmas arising from positive illusions. (shrink)

Moral encroachment states that moral factors can make a difference to what we are epistemically justified in believing. I present two motivating cases that resemble a common example in the moral encroachment literature to show that the agent's commitments and beliefs, and not the moral factors of the situation, influence epistemic justification. I call this view Structural Encroachment.

Several philosophers have recently challenged cognitivism, i.e., the view that moral judgments are beliefs, by arguing that moral judgments are evidence non-responsive in a way that beliefs are not. If you believe that P, but acquire (sufficiently strong) evidence against P, you will give up your belief that P. This does not seem true for moral judgments. Some subjects maintain their moral judgments despite believing that there is (sufficiently strong) evidence against the moral judgments. This suggests that there is a (...) mismatch between moral judgments and beliefs. This is an interesting argument. In particular, it forces the cognitivist to be more explicit about the nature of belief and the sense in which moral judgments are responsive to evidence. This paper has two aims. First, it aims to systematically examine different versions of the argument from evidence non-responsiveness. Second, it aims to outline a more nuanced understanding of the sense in which beliefs are evidence responsive that explains why the extant versions of the argument do not constitute a challenge to cognitivism.

A discussion of L.A. Paul's 'Transformative Experience' from an Author Meets Critics session at the 2015 Pacific APA.

It is widely agreed that there is a rational requirement, “Enkrasia”, which requires that you intend what you believe you ought to do. This paper argues that Enkrasia is not an independent requirement of practical rationality: it is a special case of the requirement to be instrumentally rational. I argue for this view of Enkrasia through an analysis of an all‐things‐considered belief about what you ought to do. Believing, all‐thing‐considered, that you ought to φ implies being settled on a set (...) of options from which to take an option. I argue that this state of being settled on a set of options cannot be a matter of believing. Rather, it should be understood as intending that you do what you ought to do out of that set. If an all‐things‐considered belief implies such an intention, however, satisfying Enkrasia is a matter of satisfying the requirement to intend a necessary means to an end that you intend [*published with open access].

In this paper I argue against Analytic Normative Naturalism by suggesting that the view cannot capture the way that normative concepts figure in advice. To establish this conclusion, I identify several links between normative concepts and advice and argue that, if Analytic Normative Naturalism were true, these links would not obtain.

Two or more attitudinal states are incoherent if and only if, necessarily, under conditions of full transparency, you are disposed to give up one of them. This is roughly the account of incoherence that has recently been put forward by Alex Worsnip (2018). In this paper, I argue that Worsnip’s account of incoherence is incorrect. Not only does it fail to be fully general (i.e., it does not allow us to assess the coherence of all combinations of attitudes), but it (...) also implies that an agent is necessarily incoherent just in virtue of being in one attitudinal state.

Weakness of the will remains a perplexing issue. Though philosophers have made substantial progress in homing in on what counts as a weak will, there is little agreement on whether weakness of the will is irrational, and if so, why. In this paper, we take an empirical approach towards the rationality of weakness of the will. After introducing the philosophical debate, we present the results of an empirical study that reveals that people take a “dual sensitivity”, as we shall put (...) it, towards assessing the rationality of weak-willed behavior. Put succinctly, intending X against your value judgements is assessed irrational; yet, in the same situation, intending X is assessed significantly less irrational if you judge X as something you ought to do. After discussing this result, we turn to the question of whether there is a plausible theory of rationality than can account for the dual sensitivity of the rationality assessments. We show that a success-based account can make sense of the dual sensitivity our empirical results reveal. (shrink)

The conception of rationality as Reasons Responsiveness (RR) has seen a revival in the literature. However, RR faces the indeterminacy problem: an agent may be instrumentally irrational even without failing to respond correctly to reasons. Reasons do not conclusively determine choice, but this should not be possible on RR. Hybrid Voluntarism (HV), which is supposed to apply particularly to cases where “reasons run out”, may be a solution. According to Ruth Chang, we can create will-based reasons through commitment if the (...) given reasons balance. HV is attractive since it seems to explain instrumental irrationality and preserve RR’s distinctive appeal. In this paper, I argue that HV fails to save RR in the face of indeterminacy. I first suggest that we distinguish between overdetermination and underdetermination and then show that while RR may solve the former, it fails with the latter. Therefore, we are still left with a case of irrationality without a failure to respond correctly to reasons. (shrink)
