To be able to say what practical reasoning is, we first need to say what reasoning is and what the conclusion of a process of reasoning is. I shall do this in sections 1 and 2. We can then make a distinction between practical and theoretical reasoning. There are three main ways to do this, which I shall survey in sections 3 to 5. I shall end by suggesting that there are different kinds of practical reasoning.

Imagine I hold up a Granny Smith apple for all to see. You would thereby gain justified beliefs that it was green, that it was apple, and that it is a Granny Smith apple. Under classical foundationalism, such simple visual beliefs are mediately justified on the basis of reasons concerning your experience. Under dogmatism, some or all of these beliefs are justified immediately by your experience and not by reasons you possess. This paper argues for what I call the looks (...) view of the justification of simple visual beliefs. According to the looks view, such beliefs are mediately justified on the basis of reasons concerning how the relevant things look. Unlike under classical foundationalism, under the looks view as I develop it, these reasons are public. They are public with respect to both their content and possession: with respect to content, they are not about ourselves and our experiences, and with respect to their possession, many people can have the very same looks-related reasons.

What is the relation between entailment and reasons for belief? In this paper, I discuss several answers to this question, and I argue that these answers all face problems. I then propose the following answer: for all propositions p1,...,pn and q, if the conjunction of p1,..., and pn entails q, then there is a reason against a person's both believing that p1,..., and that pn and believing the negation of q. I argue that this answer avoids the problems that the (...) other answers to this question face, and that it does not face any other problems either. I end by showing what the relation between deductive logic, reasons for belief and reasoning is if this answer is correct. (shrink)

If you ought to perform a certain act, and some other action is a necessary means for you to perform that act, then you ought to perform that other action as well – or so it seems plausible to say. This transmission principle is of both practical and theoretical significance. The aim of this paper is to defend this principle against a number of recent objections, which (as I show) are all based on core assumptions of the view called actualism. (...) I reject actualism, provide an alternative explanation of its plausible features, and present an independent argument for the transmission principle. (shrink)

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)

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

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)

Since Aristotle it has been common among philosophers to distinguish between two fundamental types of reasoning, theoretical and practical. We do not only want to work out what is the case but also what we ought to do. This article offers a logical analysis of instrumental reasoning, which is the paradigm of practical reasoning. In the first section I discuss the major types of instrumental reasoning and show why the accounts of most authors are defective. On the basis of this (...) discussion, I demonstrate in the second section that different types of normative conclusions are derivable from instrumental arguments and I show that it is an argument’s logical structure that determines what type of conclusion this is. (shrink)

In this paper, I want to challenge some common assumptions in contemporary theories of practical rationality and intentional action. If I am right, the fact that our intentions can be rationalised is widely misunderstood. Normally, it is taken for granted that the role of rationalisations is to show the reasons that the agent had to make up her mind. I will argue against this. I do not object to the idea that acting intentionally is, at least normally, acting for reasons, (...) but I will propose a teleological reading of the expression ‘for reasons.’ On this reading, it is quite possible to act for reasons without having reasons to act. In a similar way, paradigmatic cases of cogent practical reasoning do not require the transference of justification from the premises to the practical conclusion. (shrink)

This paper presents a new objection to the buck-passing account of value. I distinguish the buck-passing account of predicative value from the buck-passing account of attributive value. According to the latter, facts about attributive value reduce to facts about reasons and their weights. But since facts about reasons’ weights are themselves facts about attributive value, this account presupposes what it is supposed to explain. As part of this argument, I also argue against Mark Schroeder's recent account of the weights of (...) reasons, which purports to explain the weights of reasons in terms of further reasons without circularity. I then argue that if we abandon the buck-passing account of attributive value, it would be ad hoc and unjustifiable to continue to endorse the buck-passing account of predicative value. In short, there seems to be little hope for the buck-passing account in either form. The paper ends by sketching a novel alternative theory according to which reasons are analysed in terms of the attributive value of motives. I suggest that a normative reason to is something that would be a good motive for -ing. At least at first glance, this view has numerous merits and few problems. (shrink)

This chapter examines an evidentialist ethics of belief, and W. K. Clifford’s proposal in particular. It argues that regardless of how one understands the notion of evidence, it is implausible that we could have a moral obligation to refrain from believing something whenever we lack sufficient evidence. Alternatively, this chapter argues that there are wide-scope conditional requirements on beliefs but that these requirements can be met without having sufficient evidence for the belief in question. It then argues that we are (...) epistemically, though not morally, required to form epistemically valuable beliefs. However, these beliefs, too, need not be beliefs for which we have sufficient evidence—epistemically good beliefs need not be based on sufficient evidence. (shrink)

This paper argues that practical reasoning is a mental process which leads a person from a set of existent mental states to an intention. In Section 1, I defend this view against two other proposals according to which practical reasoning either concludes in an action itself or in a normative belief. Section 2 discusses the correctness of practical reasoning and explains how the correctness of instrumental reasoning can be explained by the logical relations that hold between the contents of the (...) mental states. In Section 3, I explore the correctness of normative practical reasoning. I conclude with the sceptical view that correct practical reasoning cannot require us to intend to do what we believe we ought to do. (shrink)

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)

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)

This paper seeks a better understanding of the elements of practical reasoning: premises and conclusion. It argues that the premises of practical reasoning do not normally include statements such as ‘I want to ϕ’; that the reasoning in practical reasoning is the same as in theoretical reasoning and that what makes it practical is, first, that the point of the relevant reasoning is given by the goal that the reasoner seeks to realize by means of that reasoning and the subsequent (...) action; second, that the premises of such reasoning show the goodness of the action to be undertaken; third, that the conclusions of such reasoning may be actions or decisions, that can be accompanied by expressions of intention, either in action, or for the future; and that these are justified, and might be contradicted, in ways that are not only peculiar to them (i.e. in ways that diverge from those found in theoretical reasoning), but are distinctively practical, in that they involve reference to reasons for acting and to expressions of intention, respectively.1. (shrink)

In this paper, I examine an account of instrumental reasoning recently put forth by John Broome. His key suggestion is that anyone who engages in reasoning about his intentions also believes that he will do what he intends to do and that combined with a belief about necessary means this creates rational pressure towards believing that one will take the necessary means. I argue that Broome’s model has three significant problems; his key premise is false—the sincere expression of an intention (...) does not entail the belief that one will successfully execute that intention; his account yields a model of instrumental reasoning that is uncomfortably reflective; he seems unable to explain the rational pressure towards taking necessary means that arises directly from having an end and an instrumental belief. All three problems, I argue, are a consequence of Broome’s inadequate position on what it is to intend to do something. (shrink)

An alleged counterexample to causal decision theory, put forward by Andy Egan, is studied in some detail. It is argued that Egan rejects the evaluation of causal decision theory on the basis of a description of the decision situation that is different from—indeed inconsistent with—the description on which causal decision theory makes its evaluation. So the example is not a counterexample to causal decision theory. Nevertheless, the example shows that causal decision theory can recommend unratifiable acts which presents a problem (...) in the dynamics of intentions. It is argued that we can defuse this problem if we hold that decision theory is a theory of rational decision making rather than a theory of rational acts. It is shown how decisions can have epistemic side-effects that are not mediated by the act and that there are cases where one can only bring oneself to perform the best act by updating by imaging rather than by conditioning. This provides a pragmatic argument for updating by imaging rather than by conditioning in these cases. (shrink)

The paper presents a non-monotonic inference relation on a language containing a conditional that satisfies the Ramsey Test. The logic is a weakening of classical logic and preserves many of the ‘paradoxes of implication’ associated with the material implication. It is argued, however, that once one makes the proper distinction between supposing that something is the case and accepting that it is the case, these ‘paradoxes’ cease to be counterintuitive. A representation theorem is provided where conditionals are given a non-bivalent (...) semantics and epistemic states are represented via preferential models. (shrink)

I first distinguish between different forms of the buck-passing account of value and clarify my target in other respects on buck-passers' behalf. I then raise a number of problems for the different forms of the buck-passing view that I have distinguished.

We present a modal logic called (logic of intention and attempt) in which we can reason about intention dynamics and intentional action execution. By exploiting the expressive power of , we provide a formal analysis of the relation between intention and action and highlight the pivotal role of attempt in action execution. Besides, we deal with the problems of instrumental reasoning and intention persistence.

It is sometimes suggested that there are two kinds of reasoning: inferential reasoning and non-inferential reasoning. However, it is not entirely clear what the difference between these two kinds of reasoning is. In this paper, I try to answer the question what this difference is. I first discuss three answers to this question that I argue are unsatisfactory. I then give a different answer to this question, and I argue that this answer is satisfactory. I end by showing that this (...) answer can help to resolve some disagreements in which the difference between inferential and noninferential reasoning plays a role. (shrink)

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)

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

This paper examines the nature of the specific grasp involved in moral understanding. After discussing Hills's ability account of that central component of moral understanding in light of problematic cases, I argue that moral grasp is best conceived of as a type of knowledge that is grounded in a subject's moral appreciation. I then show how and why the relevant notion of moral appreciation is connected to moral virtues and to one's affective and motivational engagement with moral reasons. Finally, I (...) discuss the connection between moral appreciation and a subject's ability to offer moral explanations in relation to the debate between pessimists and optimists about moral understanding's testimonial transmission.

Can we think of a task in a distinctively practical way? Can there be practical concepts? In recent years, epistemologists, philosophers of mind, as well as philosophers of psychology have appealed to practical concepts in characterizing the content of know-how or in explaining certain features of skilled action. However, reasons for positing practical concepts are rarely discussed in a systematic fashion. This paper advances a novel argument for the psychological reality of practical concepts that relies on evidence for a distinctively (...) productive kind of reasoning. (shrink)

According to the Aristotelian Thesis, the conclusion of practical reasoning is an action. Critics argue against it by pointing to cases in which some interference or inability prevents the production of action, yet in which that interference or inability doesn’t impugn the success of an agent’s reasoning. Some of those critics suggest instead that practical reasoning concludes in an intention, while others suggest it concludes in a belief with normative content, such as a belief about what one has conclusive, or (...) sufficient, reason to do. In this paper, I argue that we should allow that practical reasoning could conclude in either an intention or a belief with normative content. I begin by developing an objection to the Aristotelian Thesis, showing how the objection will not also undermine the possibility of practical reasoning concluding in an intention or a belief. I then respond to an argument from Joseph Raz designed to exclude the possibility of intentions as conclusions of practical reasoning. Lastly, I show how the worry that belief isn’t sufficiently “practical” to qualify as a conclusion of practical reasoning is misplaced. (shrink)

ABSTRACTA widespread view in the philosophy of mind and action holds that intentions are propositional attitudes. Call this view ‘Propositionalism about Intention’. The key alternative holds that intentions have acts, or do-ables, as their contents. Propositionalism is typically accepted by default, rather than argued for in any detail. By appealing to a key metaphysical constraint on any account of intention, I argue that on the contrary, it is the Do-ables View which deserves the status of the default position, and Propositionalism (...) which bears the burden of proof. I go on to show that this burden has not been met in the literature. (shrink)

A good surgeon knows how to perform a surgery; a good architect knows how to design a house. We value their know-how. We ordinarily look for it. What makes it so valuable? A natural response is that know-how is valuable because it explains success. A surgeon’s know-how explains their success at performing a surgery. And an architect’s know-how explains their success at designing houses that stand up. We value know-how because of its special explanatory link to success. But in virtue (...) of what is know-how explanatorily linked to success? This essay provides a novel argument for the thesis that know-how’s special link to success is to be explained at least in part in terms of its being, or involving, a doxastic attitude that is epistemically alike propositional knowledge. It is argued that the role played by know-how in explaining intentional success shows that the epistemic differences between know-how and knowledge, if any, are less than usually thought; and that "revisionary intellectualism", the view that know-how is true belief that might well fall short of knowledge, is not really a stable position. If its explanatory link to success is what makes know-how valuable, an upshot of my argument is that the value of know-how is due, to a considerable extent, to its being, or involving, a kind of propositional knowledge.

We argue that intentions are beliefs—beliefs that are held in light of, and made rational by, practical reasoning. To intend to do something is neither more nor less than to believe, on the basis of one’s practical reasoning, that one will do it. The identification of the mental state of intention with the mental state of belief is what we call strong cognitivism about intentions. It is a strong form of cognitivism because we identify intentions with beliefs, rather than maintaining (...) that beliefs are entailed by intentions or are components of them. (shrink)

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)

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.

This critical note concerns John Broome's bookRationality through Reasoning(2013). Broome claims that rationality amounts to satisfying rational requirements as opposed to responding correctly to reasons. My critique focuses on two issues. First, I try to show that Broome's account of rational requirements, in particular his answer to the so-called ‘symmetry-problem’, presupposes that responding correctly to reasons is part of rationality. Secondly, in discussing Broome's account of reasoning I criticize his claim that first-order reasoning involves no appeal to reasons and, hence, (...) no normative thoughts on behalf of the reasoner. (shrink)

R. Jay Wallace argues that the normativity of instrumental rationality can be traced to the independent rational requirement to hold consistent beliefs. I present three objections to this view. John Broome argues that there is a structural similarity between the rational requirements of instrumental rationality and belief consistency. Since he does not reduce the former to the latter, his view can avoid the objections to Wallace’s view. However, we should not think Broome’s account explains the whole of instrumental rationality since (...) agents with consistent intentions can still fail in their instrumental reasoning. This consideration makes Broome’s approach vulnerable to a line of criticism that both he and Wallace present against Christine Korsgaard’s conception of instrumental rationality. (shrink)

What motivates the benevolent or charitable agent is regard for another’s good or well-being, but talk about regard for others’ good or well- being is simply talk about benevolence or charity in different terms. Yet Hume clearly holds that the regard for another’s good is a motive to produce benevolent acts that is distinct from a sense of their benevolence. So what is the difference? ‘Well’, one might say, ‘intuitively, rights are very different from wellbeing.’ Yes indeed. And that, I (...) shall contend, is Hume’s point. My general contention is that Hume’s discussion of justice is in fact an attack on that concept of rights we think of as having motivated the American and French revolutions, a concept that is still (deplorably in my view) prevalent. I think the very fact that it is so prevalent and so sanctified by its position in the American Constitution has blinded most readers to the power and plausibility of Hume’s attack, which I shall try to defend.

The Wide-Scope approach to instrumental reason holds that the requirement to intend the necessary means to your ends should be understood as a requirement to either intend the means, or else not intend the end. In this paper I explain and defend a neglected version of this approach. I argue that three serious objections to Wide-Scope accounts turn on a certain assumption about the nature of the reasons that ground the Wide-Scope requirement. The version of the Wide-Scope approach defended here (...) allows us to reject this assumption, and so defuse the objections. (shrink)

It is a widely-held thesis that the content of intentions can be characterized in terms of the truth of a proposition. In this paper I try to reject this idea. First, I argue that, at least for ordinary cases of intention, there cannot be any proposition such that the intention is fulfilled if, and only if, such a proposition is true. After that, I propose an alternative account for the content of intentions. I argue that this content must ultimately involve (...) a particular acting by the agent. (shrink)

This thesis justifies the need for and develops a new integrated model of practical reasoning and argumentation. After framing the work in terms of what is reasonable rather than what is rational (chapter 1), I apply the model for practical argumentation analysis and evaluation provided by Fairclough and Fairclough (2012) to a paradigm case of unreasonable individual practical argumentation provided by mass murderer Anders Behring Breivik (chapter 2). The application shows that by following the model, Breivik is relatively easily able (...) to conclude that his reasoning to mass murder is reasonable – which is understood to be an unacceptable result. Causes for the model to allow such a conclusion are identified as conceptual confusions ingrained in the model, a tension in how values function within the model, and a lack of creativity from Breivik. Distinguishing between dialectical and dialogical, reasoning and argumentation, for individual and multiple participants, chapter 3 addresses these conceptual confusions and helps lay the foundation for the design of a new integrated model for practical reasoning and argumentation (chapter 4). After laying out the theoretical aspects of the new model, it is then used to re-test Breivik’s reasoning in light of a developed discussion regarding the motivation for the new place and role of moral considerations (chapter 5). The application of the new model shows ways that Breivik could have been able to conclude that his practical argumentation was unreasonable and is thus argued to have improved upon the Fairclough and Fairclough model. It is acknowledged, however, that since the model cannot guarantee a reasonable conclusion, improving the critical creative capacity of the individual using it is also of paramount importance (chapter 6). The thesis concludes by discussing the contemporary importance of improving practical reasoning and by pointing to areas for further research (chapter 7). (shrink)

Like all reasoning, practical reasoning is a process that takes a person from some of her existing mental states to a new mental state. Theoretical reasoning concludes in a belief; practical reasoning in an intention. This paper concentrates on instrumental reasoning, a species of practical reasoning in general. It argues that instrumental reasoning is correct if the content of the reasoning is a valid derivation, just as theoretical reasoning is correct if its content is a valid derivation. It also argues (...) that neither theoretical nor practical reasoning gives a reason for its conclusion. If a piece of reasoning is correct, it concludes in a state - a belief or an intention - that is rationally required by the states it is derived from, but rationally requiring a conclusion is not the same as giving a reason for it.

Often our reason for doing something is an "instrumental reason": that doing that is a means to doing something else that we have reason to do. What principles govern this "instrumental transmission" of reasons from ends to means? Negatively, I argue against principles often invoked in the literature, which focus on necessary or sufficient means. Positively, I propose a principle, "General Transmission," which answers to two intuitive desiderata: that reason transmits to means that are "probabilizing" and "nonsuperfluous" with respect to (...) the relevant end. I then apply General Transmission to the debate over "detachment": whether "wide-scope" reason for a material conditional or disjunction implies "narrow-scope" reason for the consequent or disjuncts.

Some intuitive normative principles raise vexing 'detaching problems' by their failure to license modus ponens. I examine three such principles (a self-reliance principle and two different instrumental principles) and recent stategies employed to resolve their detaching problems. I show that solving these problems necessitates postulating an indefinitely large number of senses for 'ought'. The semantics for 'ought' that is standard in linguistics offers a unifying strategy for solving these problems, but I argue that an alternative approach combining an end-relational theory (...) of normativity with a comparative probabilistic semantics for 'ought' provides a more satisfactory solution. (shrink)

In this paper I take up the question of whether and in what sense action might be the conclusion of practical reasoning and argue against the answer provided by Sebastian Rödl's account of practical reasoning. Rödl's account aspires to steer a middle ground between the attitudinal and the neo-Aristotelian accounts of practical reasoning, by proposing that its conclusion is at once a thought and a movement. This account is worth considering for it promises to explain both practical reasoning's practicality and (...) its rationality in one move. But, I argue in this paper, a Rödlian account—an account which grants Rödl's central theses—fails to deliver on its promise. The reason is that, like others, a Rödlian also assumes that the only sense in which practical reasoning is practical is the sense in which it has a conclusion. Challenging this assumption in the right way, I finally suggest, helps us reassess the task of explaining practical reasoning in a way that goes beyond Rödlian, attitudinal and neo-Aristotelian accounts alike. (shrink)

I argue that, in experiencing a recalcitrant emotion, one does not violate a rational requirement of any sort. Rational requirements, as the expression has come to be used, are requirements of coherence. Accordingly, my argument is that there is nothing incoherent in any way about experiencing a recalcitrant emotion. One becomes incoherent only if one allows the emotion to influence one's reasoning and/or action, in which case one violates the ‘consistency principle’ and/or the ‘enkratic principle’. From the standpoint of rationality, (...) it would even be counterproductive to put subjects under the obligation that their emotional experiences and their evaluative judgements must always fit together. When we nevertheless intuitively sense that the subject is irrational in experiencing a recalcitrant emotion this is in cases in which the emotion challenges the subject's agential identity. However, emotions can, but need not, challenge one's agential identity, and, furthermore, perceptions can do so as well. In any case, challenges of this kind do not involve the violation of a rational requirement. (shrink)
