This paper argues that there is a problem for the justificatory significance of perceptions that has been overlooked thus far. Assuming that perceptual experiences are propositional attitudes and that only propositional attitudes which assertively represent the world can function as justifiers, the problem consists in specifying what it means for a propositional attitude to assertively represent the world without losing the justificatory significance of perceptions—a challenge that is harder to meet than might first be thought. That there is such a (...) problem can be seen by reconsidering and modifying a well-known argument to the conclusion that beliefs cannot be justified by perceptions but only by other beliefs. Nevertheless, the aim of the paper is not to conclude that perceptions are actually incapable of justifying our beliefs but rather to highlight an overlooked problem that needs to be solved in order to properly understand the justificatory relationship between perceptions and beliefs.

In this paper I investigate whether there are genuine and irreducible pressures of diachronic rationality grounded on the structure of the subject rather than on substantive considerations, such as pragmatic ones. I argue that structural pressures of diachronic rationality have a limited scope. The most important pressure only tells against arbitrary interference with the mechanisms for the retention of attitudes over time. I then argue that in the practical case, a substantial account in terms of the agent's temporal identity appears (...) more promising than a purely structural one, but in the end it still leaves many questions about diachronic practical rationality underdetermined.

ZusammenfassungIn der zeitgenössischen metaethischen Literatur gibt es eine gängige Unterscheidung zwischen zwei Arten von Sollen: dem Sollen substanzieller normativer Gründe und dem Sollen struktureller Forderungen oder Prinzipien der Rationalität. Diese Unterscheidung zwischen Gründesollen und rationalem Sollen führt zur Frage, wie beide zusammenhängen. Eine weit verbreitete Theorie behauptet, dass die Normativität des rationalen Sollens durch die Normativität des Gründesollens zu erklären ist. Ich argumentiere dafür, dass keine Variante dieser Theorie des Primats normativer Gründe in der Lage ist, die Normativität des rationalen (...) Sollens befriedigend zu erklären. Aus meiner Kritik leite ich zwei Adäquatheitsbedingungen ab, die eine Theorie der Normativität der Rationalität einholen muss. Im letzten Teil skizziere ich eine alternative Theorie, deren grundlegender Gedanke ist, dass Rationalitätsforderungen als konstitutive Normen vernünftiger Aktivität zu verstehen sind. Wie ich zeigen werde, verspricht sie beide Adäquatheitsbedingungen einzuholen. (shrink)

For many epistemologists, and for many philosophers more broadly, it is axiomatic that rationality requires you to take the doxastic attitudes that your evidence supports. Yet there is also another current in our talk about rationality. On this usage, rationality is a matter of the right kind of coherence between one's mental attitudes. Surprisingly little work in epistemology is explicitly devoted to answering the question of how these two currents of talk are related. But many implicitly assume that evidence -responsiveness (...) guarantees coherence, so that the rational impermissibility of incoherence will just fall out of the putative requirement to take the attitudes that one's evidence supports, and so that coherence requirements do not need to be theorized in their own right, apart from evidential reasons. In this paper, I argue that this is a mistake, since coherence and evidence -responsiveness can in fact come into conflict. More specifically, I argue that in cases of misleading higher-order evidence, there can be a conflict between believing what one's evidence supports and satisfying a requirement that I call “inter-level coherence ”. This illustrates why coherence requirements and evidential reasons must be separated and theorized separately. (shrink)

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

It is standard, both in the philosophical literature and in ordinary parlance, to assume that one can fall short of responding to all one’s moral reasons without being irrational. Yet when we turn to epistemic reasons, the situation could not be more different. Most epistemologists take it as axiomatic that for a belief to be rational is for it to be well-supported by epistemic reasons. We find ourselves with a striking asymmetry, then, between the moral and epistemic domains concerning what (...) is taken for granted about whether failures to respond to reasons are failures of rationality. My aim in this paper is to interrogate this asymmetry, and ultimately to argue that the asymmetry is groundless. Instead, I will offer an error theory to explain the asymmetry in intuitions. This error theory suggests that we should amend the conventional wisdom about the relationship between epistemic reasons and rationality. (shrink)

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.

How, if at all, does one's intention to realize an end bear on the justification for taking the means to that end? Theories that allow that intending an end directly provides a reason to take the means are subject to a well-known "bootstrapping" objection. On the other hand, "anti-psychologistic" accounts—which seek to derive instrumental reasons directly from the reasons that support adopting the end itself—have unacceptable implications where an agent faces multiple rationally permissible options. An alternative, predictive, role for intention (...) in means-end reasoning is considered and rejected. A new proposal is then developed, according to which instrumental reasons are not merely reasons to perform an act necessary for a given end, but to perform the act for the sake of that end.

According to the Desire-Based Reasons Model reasons for action are provided by desires. Many, however, are critical about the Model holding an alternative view of practical reason, which is often called valued-based. In this paper I consider one particular attempt to refute the Model, which advocates of the valued-based view often appeal to: the idea of reason-based desires. The argument is built up from two premises. The first claims that desires are states that we have reason to have. The second (...) argues that desires do not add to the stock of reasons the agent has for having them. Together the two theses entail that desires are based on reasons, which they transmit but to which they cannot add. In the paper I deal with a counterexample to the second premise: tie-breaking desires. I first distinguish two interesting cases and argue that only the second challenges the premise. Then I move onto analyze this challenge by focusing on Ruth Chang’s recent employment of it. I show that contrary to its counterintuitive appearance, the challenge can be sustained. However, I also argue that Chang overlooks the full potential of one particular response to the challenge: the introduction of higher-order reasons determining the normative significance of these desires. At the same time, I show that this response has a problem that Chang does not consider. As a result, the response can only partially disarm the challenge of tie-breaking desires; or not at all, depending on what significance we attribute to the counterexamples. (shrink)

In this paper, I analyse the nature of a particular form of theoretical reasoning—ratiocination. Ratiocination is purposeful, self-conscious, deliberatively controlled reasoning. I will argue that ratiocination concludes when the ratiocinator believes that she ought to believe p. In Section 1, I suggest that the way a reasoner’s mind moves in ratiocination is different from the way her mind moves in non-ratiocinative reasoning. Such a difference should motivate an analysis that focuses just on ratiocination. In Section 2, I provide a general (...) characterisation of ratiocination and distinguish it from non-ratiocinative reasoning. I draw a distinction between non-deliberative rational control and deliberative rational control. I then argue that the ratiocinator always exercises the latter. Since theoretical reasoning is a norm-governed activity and since ratiocination involves deliberatively controlled reasoning, the ratiocinator necessarily tries to control her mental movements in a way that is in line with the normative requirements of this activity. In Section 3, I argue that ratiocination ends when the ratiocinator believes that she ought to believe p. I further explain the nature of the ‘ought’ in the ratiocinator’s belief that she ought to believe p. In Section 4, I address possible objections to the account on offer and explain why my account does not undermine our general understanding of the nature of theoretical reasoning. I explain that my claim is compatible with the claim that reasons to be rational are transparent to reasons to believe p. I also discuss why the ratiocinator’s belief that she ought to believe p is not an intermediate stage in ratiocination. Finally, I argue that ratiocination, as described, is compatible with the claim that belief is truth-governed. (shrink)

I argue that the "why be rational?" challenge raised by John Broome and Niko Kolodny rests upon a mistake that is analogous to the mistake that H.A. Pritchard famously claimed beset the “why be moral?” challenge. The failure to locate an independent justification for obeying rational requirements should do nothing whatsoever to undermine our belief in the normativity of rationality. I suggest that we should conceive of the demand for a satisfactory vindicating explanation of the normativity of rationality instead in (...) terms of the demand for a philosophical characterisation of rationality that can do something to explain why rational requirements are the kinds of things that are, by their very nature, normative. I consider several accounts that have recently been offered – the distinctive-object account, the proper functioning account, and the subjective reasons account – and argue that none succeeds in meeting this challenge. I then sketch a new account, the “first-personal authority account”, which holds that rational requirements are what I call “standpoint-relative demands” concerning the attitudes we ought to have and form; and that complying with rational requirements is a matter of honouring our first-personal authority as agents. I suggest that the first-personal authority account does a better job of meeting the challenge. (shrink)

How does it happen that our beliefs about what we ought to do cause us to intend to do what we believe we ought to do? This is what John Broome calls the "motivation question." Broome’s answer to the motivation question is that we can bring ourselves, by our own efforts, to intend to do what we believe we ought to do by exercising a special agential capacity: the capacity to engage in what he calls enkratic reasoning. My aim is (...) to evaluate this answer. In doing so, I shall focus on three core aspects of Broome’s overall account: his account of ought, his account of enkratic rationality, and his account of enkratic reasoning in particular. In each case I suggest there are problems. (shrink)

Formal epistemologists often claim that our credences should be representable by a probability function. Complete probabilistic coherence, however, is only possible for ideal agents, raising the question of how this requirement relates to our everyday judgments concerning rationality. One possible answer is that being rational is a contextual matter, that the standards for rationality change along with the situation. Just like who counts as tall changes depending on whether we are considering toddlers or basketball players, perhaps what counts as rational (...) shifts according to whether we are considering ideal agents or creatures more like ourselves. Even though a number of formal epistemologists have endorsed this type of solution, I will argue that there is no way to spell out this contextual account that can make sense of our everyday judgments about rationality. Those who defend probabilistic coherence requirements will need an alternative account of the relationship between real and ideal rationality. (shrink)

How are justified belief and rational belief related? Some philosophers think that justified belief and rational belief come to the same thing. Others take it that justification is a matter of how well a particular belief is supported by the evidence, while rational belief is a matter of how well a belief coheres with a person’s other beliefs. In this paper, I defend the view that justification is a dimension of rationality, a view that can make sense of both of (...) these conflicting accounts. When it modifies belief, ‘rational’ is a multidimensional adjective, as there are multiple dimensions along which a belief can be rational. I will argue that one of these dimensions is justification, an account that can not only explain why philosophers give diverging theories of the relationship between justified belief and rational belief, but can also reveal why rational belief and justified belief are closely related despite being distinct.

Caring is a complex attitude. At first look, it appears very complex: it seems to involve a wide range of emotional and other dispositions, all focused on the object cared about. What ties these dispositions together, so that they jointly comprise a single attitude? I offer a theory of caring, the Attentional Theory, that answers this question. According to the Attentional Theory, caring consists of just two, logically distinct dispositions: a disposition to attend to an object and hence to considerations (...) pertaining to it, and a disposition to respond to the real or apparent reasons those considerations provide. The emotional and other attitudes involved in caring are instantiations of these two, more general dispositions; and these apparently diverse emotional and other dispositions are connected because the real or apparent reasons to which they are dispositions to respond are connected, in structured “packages.” The fact that the reasons to which a caring agent responds are connected in this way provides the basis for an error theory, explaining why it appears as if the emotions involved in caring are governed by rational coherence requirements.

Philosophers interested in the fitting attitude analysis of final value have devoted a great deal of attention to the wrong kind of reasons problem. This paper offers an example of the reverse difficulty, the wrong kind of value problem. This problem creates deeper challenges for the fitting attitude analysis and provides independent grounds for rejecting it, or at least for doubting seriously its correctness.

My dissertation is a systematic defense of the claim that what it is to be rational is to correctly respond to the reasons you possess. The dissertation is split into two parts, each consisting of three chapters. In Part I--Coherence, Possession, and Correctly Responding--I argue that my view has important advantages over popular views in metaethics that tie rationality to coherence (ch. 2), defend a novel view of what it is to possess a reason (ch. 3), and defend a novel (...) view about what it is to act and hold attitudes for normative reasons (ch. 4). In Part II--Foundationalism, Deception, and The Importance of Being Rational--I argue that foundationalists about epistemic rationality should think that the foundational beliefs are held for sufficient reasons (ch. 5), argue that my view solves the New Evil Demon problem for externalism (and solves a related and underapprieciated problem) (ch. 6), and argue that my view can vindicate the thought that we ought to be rational (ch. 7).

An important recent debate in the philosophy of action has focused on whether there is a persistence requirement on intention and, if there is, what its proper formulation should be. At one extreme, Bratman has defended what I call Strong Persistence, according to which it’s irrational to abandon an intention except for an alternative that is better supported by one’s reasons. At the other extreme, Tenenbaum has argued that there isn’t a persistence requirement on intention at all. In the middle, (...) philosophers like Broome, Ferrero, and Paul have defended persistence requirements with varying degrees of stringency while agreeing that Bratman’s proposed requirement is too strong. In this paper I side with Bratman in defending Strong Persistence. I argue, however, that Bratman’s own argument in favor of it is defective and an easy prey to the multiple objections that have been leveled against it. I thus offer in its place a “first-personally addressed constitutivist argument” whose aim is to show to the minimally reflective agent the kind of commitment involved in deciding and forming an intention in situations of incomparability—which are taken to be the litmus test for persistence requirements—and the persistence rational requirement governing it. Along the way I respond to the objections against Strong Persistence and explain why my argument represents an improvement over Bratman’s. (shrink)

The requirements of rationality are fundamental in practical and theoretical philosophy. Nonetheless, there exists no correct account of what constitutes rational requirements. This paper attempts to provide a correct constitutive account of ‘rationality requires’. I argue that rational requirements are grounded in ‘necessary explanations of subjective incoherence’, as I shall put it. Rationality requires of you to X if and only if your rational capacities, in conjunction with the fact that you not-X, explain necessarily why you have a non-maximal degree (...) of subjective coherence.

Does a coherentist version of rationality issue requirements on states? Or does it issue requirements on processes? This paper evalu- ates the possibility of process-requirements. It argues that there are two possible definitions of state- and process-requirements: a satisfaction- based definition and a content-based definition. I demonstrate that the satisfaction-based definition is inappropriate. It does not allow us to uphold a clear-cut distinction between state- and process-requirements. We should therefore use a content-based definition of state- and pro- cess-requirements. However, a (...) content-based definition entails that ra- tionality does not issue process-requirements. Content-based process- requirements violate the principle that ‘rationality requires’ implies ‘can satisfy’. The conclusion of this paper therefore amounts to a radical re- jection of process-requirements of rationality. (shrink)

In this paper I argue that the enkratic principle in its classic formulation may not be a requirement of rationality. The investigation of whether it is leads to some important methodological insights into the study of rationality. I also consider the possibility that we should consider rational requirements as a subset of a broader category of agential requirements.

In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show that (...) there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability.

As Kant claimed in the Groundwork, and as the idea has been developed by Korsgaard 1997, Bratman 1987, and Broome 2002. This formulation is agnostic on whether reasons for ends derive from our desiring those ends, or from the relation of those ends to things of independent value. However, desire-based theorists may deny, against Hubin 1999, that their theory is a combination of a principle of instrumental transmission and the principle that reasons for ends are provided by desires. Instead, they (...) may say, there is just one principle, a principle of, if you will, instrumental transmutation: if one desires the end, then one has reason to take the means. See the discussion of General Production, in section 8, for a doubt about this. (shrink)

On one conception of practical rationality, being rational is most fundamentally a matter of avoiding incoherent combinations of attitudes. This conception construes the norms of rationality as codified by rational requirements, and one plausible rational requirement is that you not be akratic: that you not judge, all things considered, that you ought to ϕ while failing to choose or intend to ϕ. On another conception of practical rationality, being rational is most fundamentally a matter of thinking or acting in a (...) way that’s informed by your practical reasons. This second conception construes the norms of rationality in terms that appear to allow the possibility of rational akrasia, since your capacity to act on your reasons can function at a level that need not involve deliberative judgment. Though their treatments of akrasia make them seem incompatible, I’ll argue that the two conceptions of rationality are not incompatible. It is possible to accommodate the core insight motivating defenses of ‘rational’ akrasia within the conception of rationality as codified by requirements of rational coherence. (shrink)

Are inferences, theoretical and practical, subject to requirements of rationality? If so, are these of the form 'if … ought …' or 'ought … if …'? If the latter, how are we to understand the 'if'? It seems that, in all cases, we get unintuitive implications if 'ought' connotes having reason. It is difficult to formulate such requirements, and obscure what they explain. There might also be a requirement forbidding self-contradiction. It is a good question whether self-contradiction constitutes, or evidences, (...) irrationality; but talk of a rational requirement causes trouble. (shrink)

Constructivism in ethics is the view that insofar as there are normative truths, for example, truths about what we ought to do, they are in some sense determined by an idealized process of rational deliberation, choice, or agreement. As a “first-order moral account”--an account of which moral principles are correct-- constructivism is the view that the moral principles we ought to accept or follow are the ones that agents would agree to or endorse were they to engage in a hypothetical (...) or idealized process of rational deliberation. As a “metaethical account” – an account of whether there are any normative truths and, if so, what they are like – constructivism holds that there are normative truths. These truths are not fixed by facts that are independent of the practical standpoint, however characterized; rather, they are constituted by what agents would agree to under some specified conditions of choice. In working to provide a more precise definition of constructivism in metaethics, the focus of this entry, one faces two main difficulties. The first difficulty is that constructivism comes in several varieties, each of which claims a different niche within metaethics, and some claim no space at all. The second difficulty concerns where to place constructivism on the metaethical map in relation to realism and anti-realism. These are terms of art, and it is highly contested which views count as realist and which as antirealist. These two difficulties will be addressed in what follows by focusing on the distinctive questions that constructivist theories are designed to answer. Section §1 defines the scope of constructivism in ethics, in contrast to constructivism in political theory. Sections §§2-5 illustrate the main varieties of metaethical constructivism, which are designed to account for the nature of normative truths and practical reasons. Section §6 presents the main varieties of constructivist accounts of the justification of moral judgments of right and wrong. Section §7 discusses the metaethical status of constructivism, and its distinctive import. (shrink)

It is through our actions that we affect the way the world goes. Whenever we face a choice of what to do, we also face a choice of which of various possible worlds to actualize. Moreover, whenever we act intentionally, we act with the aim of making the world go a certain way. It is only natural, then, to suppose that an agent's reasons for action are a function of her reasons for preferring some of these possible worlds to others, (...) such that what she has most reason to do is to bring about the possible world which, of all those available to her, is the one that she has most reason to want to obtain. This is what is known as the `teleological conception of practical reasons'. Whether this is the correct conception of practical reasons is important not only in its own right, but also in virtue of its potential implications for what sort of moral theory we should accept. Below, I argue that the teleological conception is indeed the correct conception of practical reasons. (shrink)

Some philosophers think that rationality consists in responding correctly to reasons, or alternatively in responding correctly to beliefs about reasons. This paper considers various possible interpretations of ‘responding correctly to reasons’ and of ‘responding correctly to beliefs about reasons’, and concludes that rationality consists in neither, under any interpretation. It recognizes that, under some interpretations, rationality does entail responding correctly to beliefs about reasons. That is: necessarily, if you are rational you respond correctly to your beliefs about reasons.

Recently, much attention has been paid to ‘rational requirements’ and, especially, to what I call ‘rational requirements of formal coherence as such’. These requirements are satisfied just when our attitudes are formally coherent: for example, when our beliefs do not contradict each other. Nevertheless, these requirements are puzzling. In particular, it is unclear why we should satisfy them. In light of this, I explore the conjecture that there are no requirements of formal coherence. I do so by trying to construct (...) a theory of error for the idea that there are such requirements. (shrink)

Niko Kolodny It is often said that there is a special class of norms, ‘rational requirements’, that demand that our attitudes be related one another in certain ways, whatever else may be the case.1 In recent work, a special class of these rational requirements has attracted particular attention: what I will call ‘requirements of formal coherence as such’, which require just that our attitudes be formally coherent.2 For example, we are rationally required, if we believe something, to believe what it (...) entails. And we are rationally required, if we intend an end, to intend what we take to be necessary means to it. The intuitive idea is that formally incoherent attitudes give rise to a certain normative tension, or exert a kind of rational pressure on each another, and this tension, or pressure, is relieved just when one of the attitudes is revised. As John Broome observes, these requirements are, by their nature, ‘wide scope’, which is to say that there is no particular attitude that one must have or lack in order to satisfy them. This is because they require just formal coherence, and there is no particular attitude that one must have or lack in order to be formally coherent. (shrink)

This paper discusses the ethical implications of perverse incentives with regard to autonomous driving. We define perverse incentives as a feature of an action, technology, or social policy that invites behavior which negates the primary goal of the actors initiating the action, introducing a certain technology, or implementing a social policy. As a special form of means-end-irrationality, perverse incentives are to be avoided from a prudential standpoint, as they prove to be directly self-defeating: They are not just a form of (...) unintended side effect that must be balanced against the main goal or value to be realized by an action, technology, or policy. Instead, they directly cause the primary goals of the actors—i.e., the goals that they ultimately pursue with the action, technology, or policy—to be “worse achieved”. In this paper, we elaborate on this definition and distinguish three ideal-typical phases of adverse incentives, where only in the last one the threshold for a perverse incentive is crossed. In addition, we discuss different possible relevant actors and their goals in implementing autonomous vehicles. We conclude that even if some actors do not pursue traffic safety as their primary goal, as part of a responsibility network they incur the responsibility to act on the common primary goal of the network, which we argue to be traffic safety.

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.

An increasingly popular view in the literature on rationality attempts to vindicate the strong normativity of rationality by giving a unifying account of rational requirements and what one ought to do in terms of reasons that fall within one’s perspective. In this paper, I pose a dilemma for such a view: one’s rationality is determined by a narrower set of reasons, such as the set of reasons that one is attending to, whereas what one ought to do is determined by (...) a broader set of reasons that comprises reasons one is not attending to. Thus, no single set of reasons can play the dual role of determining what one is rationally required to do and determining what one ought to do: either it is too broad to determine what one is rationally required to do or it is too narrow to determine what one ought to do.

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. [*published with open access]. (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.

This a review of Alex Worsnip's book 'Fitting Things Together: Coherence and the Demands of Structural Rationality'.

I argue that realism about reasons is incompatible with the possibility of reasoning with reasons, because realists are committed to the claim that we are aware of reasons by way of ordinary belief...

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.

Suppose that you do not do what you have previously decided to do. Are you to be charged with irrationality? A number of otherwise divergent theories of practical rationality hold that by default, you are; there are rational pressures, it is claimed, that favor the long-term stability and eventual execution of distal intentions. The article challenges this view by examining how these purported pressures can be spelled out. Is intention a normative commitment to act? Are intentions reasons for action – (...) or at least for retaining one's intention until the time to act has come? Or is the rationality of ‘doing as you decide’ governed by diachronic wide-scope norms, as Michael Bratman and John Broome suggest? All of these approaches are shown to raise severe problems, which suggests a more modest view: diachronic pressures on intending are at each point in time confined to the very next instant. (shrink)

Many of our beliefs behave irrationally: this is hardly news to anyone. Although beliefs’ irrational tendencies need to be taken into account, this paper argues that beliefs necessarily preserve at least a minimal level of rationality. This view offers a plausible picture of what makes belief unique and will help us to set beliefs apart from other cognitive attitudes.

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)

Properly understood, the instrumental rule says to take means that actually suffice for my end, not, as is nearly universally assumed, to intend means that I believe are necessary for my end. This alternative explains everything the standard interpretation can—and more, including grounding certain correctness conditions for exercises of our will unexplained by the standard interpretation.
