Kiesewetter defends the normativity of rationality by presenting a new solution to the problems that arise from the common assumption that we ought to be rational. He provides a defence of a reason-response conception of rationality, an evidence-relative account of reason, and an explanation of structural irrationality in relation to these accounts.

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.

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)

Many philosophers think that requirements of rationality are “wide-scope”. That is to say: they are requirements to satisfy some material conditional, such that one counts as satisfying the requirement iff one either makes the conditional’s antecedent false or makes its consequent true. These contrast with narrow-scope requirements, where the requirement takes scope only over the consequent of the conditional. Many of the philosophers who have preferred wide-scope requirements to narrow-scope requirements have also endorsed a corresponding semantic claim, namely that ordinary (...) talk about rationality, despite appearances to the contrary, expresses wide-scope claims. In doing so, they seek to avoid attributing massive error to ordinary speakers. However, it is becoming increasingly clear that the wide-scope semantics inadequately captures the meaning of ordinary talk about rationality. It seems, then, that we are left with a dilemma: either give up the view that requirements of rationality are wide-scope, or accept an implausible semantics for ordinary talk about rationality, or attribute massive error to speakers. In this paper, I argue that this dilemma is only apparent, since we can appeal to a standard kind of contextualist semantics for modals to explain why narrow-scope talk comes out true in virtue of the wide-scope requirements. My view, then, combines wide-scoping about the explanatorily fundamental requirements of rationality with a contextualist variant of a narrow-scope semantics. I argue that this view gives us the best of both worlds, as well as solving related puzzles and challenges for the extant views in the literature. (shrink)

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.

Some irrational states can be avoided in more than one way. For example, if you believe that you ought to A you can avoid akrasia by intending to A or by dropping the belief that you ought to A. This supports the claim that some rational requirements are wide-scope. For instance, the requirement against akrasia is a requirement to intend to A or not believe that you ought to A. But some writers object that this Wide-Scope view ignores asymmetries between (...) the different ways of avoiding irrationality. In this paper I defend the Wide-Scope view against recent objections of this sort from Mark Schroeder and Niko Kolodny. I argue that once we are clear about what the Wide-Scope view is committed to—and, importantly, what it is not—we can see that Schroeder and Kolodny’s objections fail. (shrink)

This article is an introduction to the recent debate about whether rationality is normative – that is, very roughly, about whether we should have attitudes which fit together in a coherent way. I begin by explaining an initial problem – the “detaching problem” – that arises on the assumption that we should have coherent attitudes. I then explain the prominent “wide-scope” solution to this problem, and some of the central objections to it. I end by considering the options that arise (...) if we reject the wide-scope solution. (shrink)

Recent views of reasons and rationality make it plausible that it can sometimes be rational to do what you have no reason to do. A number of writers have concluded that if this is so, rationality is not normative. But this is a mistake. Even if we assume a tight connection between reasons and normativity, the normativity of rationality does not require that there is always reason to be rational. The first half of this paper illustrates this point with reference (...) to the subjective reasons account of rationality. The second half suggest that this point may have been missed because of certain similarities between the subjective reasons account and the importantly different transparency account. On the transparency account, rationality seems not to be normative. I think it is often assumed that what goes for the transparency account goes for the subjective reasons account as well. But I argue that this is a mistake. A corollary is that the subjective reasons account has an important advantage over the transparency account, given how plausible it is that rationality is normative. (shrink)

Crispin Wright’s “Unified Strategy” for addressing some familiar sceptical paradoxes exploits a subtle distinction between two different ways in which we can be related to a proposition: (full-blown) belief and (mere) acceptance. The importance of the distinction for his strategy stems from his conviction that we cannot acquire any kind of evidence, either empirical or a priori, for the “cornerstones” of our cognitive projects, i.e., for those basic presuppositions of our inquiries that we must be warranted to endorse if we (...) are to claim warrant for any of the beliefs formed as a result of such inquiries: regarding the idea of a non-evidential warrant to believe a proposition as a kind of “conceptual solecism”, he doesn’t set himself the task of showing that we are evidentially warranted to believe such presuppositions, but only that of showing that we are non-evidentially warranted to accept them. In the present paper, I argue that such choice involves a fatal departure from a basic principle governing doxastic commitment—a principle that requires that we regard cornerstones propositions as propositions we are rationally committed to believe, not just entitled to accept. I press the point by presenting the Acceptance Argument, a sceptical paradox whose consideration leads to the conclusion that the Unified Strategy is caught between the Scylla of incoherently invoking a rather dubious form of epistemic alchemy and the Charybdis of placing an unexpected and apparently ad hoc restriction on the doxastic commitments we undertake by believing the things we believe. My final suggestion is that the Unified Strategy might be spared this dilemma only by undergoing a rather radical revision—a revision that would require setting aside the distinction between belief and acceptance to re-conceptualise its goal unabashedly in terms of (non-evidentially) warranted belief.

I explore the prospects of capturing and explaining, within a non-cognitivist framework, the enkratic principle of rationality, according to which rationality requires of N that, if N believes that she herself ought to perform an action, φ, N intends to φ. Capturing this principle involves making sense of both the possibility and irrationality of akrasia – of failing to intend in accordance with one’s ought thought. In the first section, I argue that the existing non-cognitivist treatments of enkrasia/akrasia by Allan (...) Gibbard and Michael Ridge are not satisfying. In the second section, I propose that non-cognitivists should perhaps say roughly the following: to think that one ought to φ is to prefer φ-ing to the alternative courses of action, or to have a stronger desire to φ than to choose any alternative action. I outline an account of the strength of desire, which allows for the possibility of intending to act against one’s strongest desires, and makes it intelligible why rationality would nevertheless require that one’s strongest desires and intentions be aligned. This would allow the non-cognitivist to explain how akrasia is both possible and irrational. In the last section, I briefly suggest that this leaves non-cognitivists in a nice position in comparison to at least some of the competition, when it comes to capturing enkrasia. (shrink)

I argue that given standard deontic logic, wide-scope rational requirements entail narrow-scope rational requirements. In particular, the widely-embraced Enkratic Principle entails that if a particular combination of attitudes is rationally forbidden, it is also rationally forbidden to believe that that combination of attitudes is required.

Argues that the normative relation of commitment is routinely overlooked by philosophers, and that investigating it reveals some interesting similarities between the moral and rational domains.

Offers a conciliatory solution to one of the central contemporary debates in the theory of rationality, the debate about the proper formulation of rational requirements. Introduces a novel conception of the “symmetry problem” for wide scope rational requirements, and sketches a theory of rational commitment as a response.

A prevalent assumption is that normativity is a unity. In this paper I argue against this assumption by demonstrating the problems it poses to a well known answer to a well known problem for taking rationality to be normative. John Broome's normative requirement relation does indeed avoid that problem, but insofar as the relation is supposed to offer a general characterisation of the normativity of rationality, it fails. It fails because it cannot capture an important aspect of the normativity of (...) rationality, that it is available to guide us. I show that if we distinguish two kinds of normativity it need not fail in this way. (shrink)

The paper is concerned with the rational requirements for suspended judgment, or what suspending judgment about a question rationally commits one to. It shows that two purported rational requirements for suspended judgment cannot both be true at the same time, at least when the entailment relation between questions is understood a certain way. The first one says that one is rationally required to suspend judgment about those questions that are entailed by the questions that one already suspends judgment about. The (...) second one says that one is rationally required to believe the presuppositions of the questions one suspends judgment about. Two plausible solutions to the problem are discussed. One of them explicates the relation of entailment between questions in an alternative manner, and the other one rejects the presupposition requirement. Either way, a closure requirement for suspended judgment can be maintained which is analogous to the closure requirement for belief. Whereas belief is ideally closed under entailment between propositions, suspended judgment is ideally closed under entailment between questions. (shrink)

How does rationality bind the agnostic, that is, the one who suspends judgment about whether a given proposition is true? In this paper I explore two alternative ways of establishing what the rational requirements of agnosticism are: the Lockean–Bayesian framework and the doxastic logic framework. Each of these proposals faces strong objections. Fortunately, however, there is a rich kernel of requirements of agnosticism that are vindicated by both of them. One can then endorse the requirements that belong to that kernel (...) without thereby committing oneself to the problematic implications that stem from either of the aforementioned proposals.

The aim of this paper is to develop a constitutivist account of instrumental normativity (an account of the requirement to take the means to one’s end as the normative standard that constitutes intentional action) that overcomes the restrictions of the neo-Anscombean variant of constitutivism without reverting to the reductivism of Kantian constitutivism. I call this account “Murdochian”, for it relies on Iris Murdoch’s conception of the practicable good.

ABSTRACTThis essay argues that in spite of the powerful arguments by Kolodny and Broome there is a reason to be rational. The suggested reason to be rational is that if an agent complies with ratio...

At the heart of the Bayesianism is a rule, Conditionalization, which tells us how to update our beliefs. Typical formulations of this rule are underspecified. This paper considers how, exactly, this rule should be formulated. It focuses on three issues: when a subject’s evidence is received, whether the rule prescribes sequential or interval updates, and whether the rule is narrow or wide scope. After examining these issues, it argues that there are two distinct and equally viable versions of Conditionalization to (...) choose from. And which version we choose has interesting ramifications, bearing on issues such as whether Conditionalization can handle continuous evidence, and whether Jeffrey Conditionalization is really a generalization of Conditionalization.

You are irrational when you are akratic. On this point most agree. Despite this agreement, there is a tremendous amount of disagreement about what the correct explanation of this data is. Narrow-scopers think that the correct explanation is that you are violating a narrow-scope conditional requirement. You lack an intention to x that you are required to have given the fact that you believe you ought to x. Wide-scopers disagree. They think that a conditional you are required to make true (...) is false. You aren’t required to have any particular attitudes. You’re just required to intend to x or not believe you ought to x. Wide-scope accounts are symmetrical insofar as they predict that you are complying with the relevant requirement just so long as the relevant conditional is true. Some narrow-scopers object to this symmetry. However, there is disagreement about why the symmetry is objectionable. This has led wide-scopers to defend their view against a number of different symmetry objections. I think their defenses in the face of these objections are, on the whole, plausible. Unfortunately for them, they aren’t defending their view against the best version of the objection. In this paper I will show that there is a symmetry objection to wide-scope accounts that both hasn’t been responded to and is a serious problem for wide-scope accounts. Moreover, my version of the objection will allow us to see that there is at least one narrow-scope view that has been seriously underappreciated in the literature. (shrink)

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.

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 paper explores the sense in which rational requirements govern our attitudes like belief and intention. I argue that there is a tension between the idea that rational requirements govern attitudes understood as standing states and the attractive idea that we can directly satisfy the requirements by performing reasoning. I identify the tension by (a) illustrating how a dispositional conception of belief can cause trouble for the idea that we can directly revise our attitudes through reasoning by considering John Broome's (...) view, and (b) advancing a general argument that a standing state cannot be directly affected by reasoning. I then propose a solution: by recognizing the proper targets of rational requirements as occurrent, rather than dispositional attitudes, we can preserve the idea that we can directly satisfy rational requirements through reasoning. (shrink)

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].

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.

According to a popular account, rationality is a kind of coherence of an agent’s mental states and, more specifically, a matter of fulfilling norms of coherence. For example, in order to be rational, an agent is required to intend to do what they judge they ought to and can do. This norm has been called ‘Enkrasia’. Another norm requires that, ceteris paribus, an agent retain their intention over time. This has been called ‘Persistence of Intention’. This paper argues that thus (...) understood norms of rationality may at times conflict. More specifically, Enkrasia and Persistence of Intention may place demands on the agent that are impossible to fulfil. In these cases, the framework of requirements does not provide us with norms that make us rational. A rival account, according to which rationality is a kind of responsiveness to one’s available reasons, can overcome the problem. (shrink)

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)

Can we employ the property of rationality in establishing what rationality requires? According to a central and formal thesis of John Broome’s work on rational requirements, the answer is ‘no’ – at least if we expect a precise answer. In particular, Broome argues that (i) the property of full rationality (i.e. whether or not you are fully rational) is independent of whether we formulate conditional requirements of rationality as having a wide or a narrow logical scope. That is, (ii) by (...) replacing a wide-scope requirement with a corresponding narrow-scope requirement (or vice versa), we do not alter the situations in which a person is fully rational. As a consequence, (iii) the property of full rationality is unable to guide us in determining whether a rational requirement has a wide or a narrow logical scope. We cannot resolve the wide/narrow scope debate by appealing to a theory of fully rational attitudes. This paper argues that (i), (ii) and (iii) are incorrect. Replacing a wide- with a corresponding narrow-scope requirement (or vice versa) can alter the set of circumstances in which a person is fully rational. The property of full rationality is therefore not independent of whether we formulate conditional requirements of rationality as having a wide or a narrow logical scope. As a consequence, the property of full rationality can guide us in determining what rationality requires – even in cases where we expect a precise answer. (shrink)

This paper discusses whether rationality, morality or prudence impose process‐requirements upon us. It has been argued that process‐requirements fulfil two essential functions within a system of rational, moral or prudential requirements. These functions are considered to prove the existence of process‐requirements. First, process‐requirements are deemed necessary to ensure that rationality, morality or prudence can guide our deliberations and actions. Second, their existence is regarded as essential for the correctness of our ordinary explanations of why a person possesses a certain degree (...) of morality, rationality or prudence. However, I argue that these two functions are unable to show the existence of process‐requirements. Instead, I propose a different essential function for process‐requirements: they are necessary for attributing the correct degree of rationality, morality or prudence to a subject who is not entirely rational, moral or prudent. This function, I argue, necessitates the existence of process‐requirements. (shrink)

In his stimulating recent book Reasons without Persons, Brian Hedden develops a novel theory of rationality that he calls Time-Slice Rationality. One of the main theses of TSR is that all rational requirements are synchronic. We argue here first that this thesis is not well-motivated. We also demonstrate that Hedden is in fact committed to an even stronger claim about the rationality of an agent at a time. Finally, we provide some arguments against the conception of rationality that results from (...) this stronger claim. (shrink)

Instrumental rationality prohibits one from being in the following state: intending to pass a test, not intending to study, and believing one must intend to study if one is to pass. One could escape from this incoherent state in three ways: by intending to study, by not intending to pass, or by giving up one’s instrumental belief. However, not all of these ways of proceeding seem equally rational: giving up one’s instrumental belief seems less rational than giving up an end, (...) which itself seems less rational than intending the means. I consider whether, as some philosophers allege, these “asymmetries” pose a problem for the wide-scope formulation of instrumental rationality. I argue that they do not. I also present an argument in favor of the wide-scope formulation. The arguments employed here in defense of the wide-scope formulation of instrumental rationality can also be employed in defense of the wide-scope formulations of other rational requirements.

Recently, Christine Bratu and Mortiz Dittmeyer have argued that Christine Korsgaard’s constitutive project fails to establish the normativity of practical principles because it fails to show why a principle’s being constitutive of a practice shows that one ought to conform to that principle. They argue that in many cases a principle’s being constitutive of a practice has no bearing on whether one ought to conform to it. In this paper I argue that Bratu and Dittmeyer’s argument fails in three important (...) respects. First, they fail to recognize the ways in which Korsgaard’s neo-Kantian view departs from more orthodox Kantian views. Second, they fail to recognize the respect in which Korsgaard’s view is a version of moral rationalism. Third, they overlook an important scope ambiguity in an important premise of their argument. A sensible way of resolving this ambiguity gives the constitutivist a reasonable response. (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.

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

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).

Este artículo defiende que las obligaciones sociales emergen de las normas de la racionalidad. A través de un análisis de los requisitos normativos de la racionalidad que gobiernan los compromisos individuales, se muestra que los agentes poseen autoridad racional para revaluar sus razones, modificar sus juicios prácticos y cambiar sus intenciones. De esta autoridad depende su autonomía racional: uno y el mismo sujeto puede obligarse a hacer algo, y revocar esta orden. Mediante un compromiso social, el deudor renuncia a su (...) autoridad y autonomía racionales en favor del acreedor, generando así una obligación en el deudor, un derecho en el acreedor, y una razón normativa relativa al deudor.

There is a growing consensus, long maintained by Derek Parfit, that there is an important distinction between what we have reason to do on the one hand, and what it is rational for us to do on the other. Philosophers are now realising that there is a conceptual distinction between rationality and normativity. Given this distinction, it thus becomes a substantive question whether rationality is genuinely normative; that is, whether there is any reason to do what rationality requires. While some (...) philosophers have argued that we sometimes have reason to do what rationality requires, it is notoriously difficult to show that there are always universal and categorical reasons to do what rationality requires. But if it is not the case that there are always universal and categorical reasons to do what rationality requires, then rationality is not genuinely normative.This dissertation offers a vindication of the normativity of rationality. I maintain that there is a robust relation between rational requirements and normative reasons. In arguing for this claim, I develop what I call the reasons-sensitive view of rationality, according to which rational requirements are normative verdicts: they are second-order claims about what there is conclusive reason of rationality to do. This view explains why there are always universal and categorical reasons to be rational. So while we may not always have most reason to do what it is rational for us to do, there is always some reason—reasons of rationality—to do what it is rational for us to do. I then show how this reasons-sensitive view addresses and responds to what I diagnose to be the major sources of skepticism about the normativity of rationality. (shrink)
