A simple reductive view of intuition holds that intuition is a type of belief. That an agent who intuits that p sometimes believes that p is false is often thought to demonstrate that the simple reductive view is false. I show that this argument is inconclusive, but also that an argument for the same conclusion can be rebuilt using the notion of rational criticisability. I then use that notion to argue that perception is also not reducible to belief, (...) and that neither intuition nor perception is reducible to credence. (shrink)

David Gauthier suggested that all genuine moral problems are Prisoners Dilemmas (PDs), and that the morally and rationally required solution to a PD is to co-operate. I say there are four other forms of moral problem, each a different way of agents failing to be in PDs because of the agents’ preferences. This occurs when agents have preferences that are malevolent, self-enslaving, stingy, or bullying. I then analyze preferences as reasons for action, claiming that this means they must not target (...) the impossible, they must be able to be acted on in the circumstances, their targets must be attainable, and having the preferences must make their targets more likely. For groups of agents to have a distribution of preferences, their preferences must jointly have those four features, this imposing a kind of universalizability requirement on possible preferences. I then claim that, if all agents began with preferences satisfying these requirements, their preferences would not be of the morally problematic sort (on pain, variously, of circularity or contradiction in the specification of their targets). Instead, they would be either morally innocent preferences, or ones which put the agents in PDs. And it would then be instrumentally rational for the agents to prefer mutual co-operation. Thus if all agents initially had rationally permissible preferences and made rational choices of actions and preferences thereafter, they would never acquire immoral preferences, and so never be rationally moved to immoral actions. Further, the states of affairs such agents would be moved to bring about would be compatible with what Rawls’ agents would chose behind a veil of ignorance. Morality therefore reduces to rationality; necessarily, the actions categorically required by morality are also categorically required by rationality. (shrink)

Social identity poses one of the most important challenges to rational choice theory, but rational choice theorists do not hold a common position regarding identity. On one hand, externalist rational choice ignores the concept of identity or reduces it to revealed preferences. On the other hand, internalist rational choice considers identity as a key concept in explaining social action because it permits expressive motivations to be included in the models. However, internalist theorists tend to reduce identity (...) to desire—the desire of a person to express his or her social being. From an internalist point of view, that is, from a viewpoint in which not only desires but also beliefs play a key role in social explanations as mental entities, this article rejects externalist reductionism and proposes a redefinition of social identity as a net of beliefs about oneself, beliefs that are indexical, robust, and socially shaped.

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. (As we’ll see, it is not implausible to regard your deliberative judgment as merely one medium for registering your practical reasons, with emotions and non-deliberative habits perhaps serving as other media.) 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)

This paper gives a new interpretation of the central section of Plato’s Symposium (199d–212a). According to this interpretation, the term ‘καλόν’, as used by Plato here, stands for what many contemporary philosophers call “intrinsic value”; and “love” (ἔρως) is in effect rational motivation, which for Plato consists in the desire to “possess” intrinsically valuable things – that is, according to Plato, to be happy – for as long as possible. An explanation is given of why Plato believes that “possessing” (...) intrinsically valuable things, at least for mortals like us, consists in actively creating instantiations of the intrinsic values, both in oneself and in the external world, and in knowing and loving these intrinsic values and their instantiations. Finally, it is argued that this interpretation reveals that Plato’s “eudaemonism” is a different and more defensible doctrine than many commentators believe. (shrink)

One principal challenge to the rationalist thesis that the demands of morality are requirements of rationality has been that posed by the "rational egoist." In attempting to answer's the egoist's challenge, some rationalists have supposed that an adequate reply must take the form of a deductive argument that "converts" the egoist by showing that her position is contradictory, arbitrary, or violates some precept that defines practical rationality as such. Here I argue (a) that such rationalist replies will fail to (...) persuade the egoist to adopt a recognizably moral way of life; (b) that this failure can be traced to epistemic assumptions that underlie typical rationalist replies; (c) that egoist conversion can better be understood by rejecting these assumptions and seeing egoist conversion as akin to a paradigm shift in the sciences; and (d) that conceptualizing egoist conversion as a paradigm shift accords with empirical psychological evidence regarding the acquisition and modification of individuals' moral attitudes and beliefs.

Here is a dilemma concerning the history of science. Can the history of scientific thought be reduced to the history of the beliefs, motives and actions of scientists? Or should we think of the history of scientific thought as in some sense independent from the history of scientists? The aim of this paper is to carve out an intermediate position between these two. I will argue that the history of scientific thought supervenes on, but not reducible to, the history of (...) scientists. There is a legitimate level of description for analyzing the history of scientific thought that does not reduce to the individual level of scientists. Yet, every aspect of the history of scientific thought is determined by the actual motives and actions of individual scientists. Maybe surprisingly, I use Imre Lakatos’s controversial concept of the rational reconstruction of the history of science in order to argue for this intermediate position. (shrink)

Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis to research (...) on human reasoning leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.

Igal Kvart RATIONAL ASSERTIBILITY, THE STEERING ROLE OF KNOWLEDGE, AND PRAGMATIC ENCROACHMENT Abstract In the past couple of decades, there were a few major attempts to establish the thesis of pragmatic encroachment – that there is a significant pragmatic ingredient in the truth-conditions for knowledge-ascriptions. Epistemic contextualism has flaunted the notion of a conversational standard, and Stanley's subject-sensitive invariantism (SSI) promoted stakes, each of which, according to their proponents, play a major role as pragmatic components in the truth conditions (...) of knowledge ascriptions. These conceptions were propelled first and foremost by examples of knowledge ascriptions with obvious pragmatic aspects that seemed to require a pragmatic component in the truth-conditions of knowledge ascriptions in order to be accounted for. However, if such examples can be adequately explained not by pragmatic encroachment purely pragmatically, the central role that such examples play in supporting these accounts will be undermined. I lay out here a new pragmatic account, offering a different, purely pragmatic picture that explains such examples, and much more. If such an account and its associated explanations are adequate, then much of a need or a motivation for pragmatic encroachment is undermined. Specifically, I will develop the notion of rational assertibility, appealing to rational norms (which are not Gricean) as interfacing with semantic and epistemic (and other) norms to yield assertibility simpliciter. More importantly, I will argue for a well-entrenched pragmatic profile of knowledge, the so-called steering role of knowledge. Knowledge ascriptions, or simple assertions (that don't invoke the notion of knowledge), it will be argued, play a pragmatic role of steering audiences in joint deliberational setups to the speaker's preferred action by invoking an impending practical inference leading to that preferred action, and of ignoring incompatible alternatives. The recognition of rational forces as affecting, sometimes strongly and predominantly, intuitions associated with knowledge ascriptions, has important implications to philosophical methodology regarding what count as evidence for semantic features. One such lesson calls for securing examples with no significant rational forces at play in order to establish semantic features. Another calls attention to the ill-suitability of employing assertibility by figures in examples featuring deliberational setups for such a purpose in view of the role that such assertibility plays in reflecting rational aspects of such figures, in addition to their epistemic and semantic characteristics. Still another lesson points to a specific role that audiences play in such deliberational setups. (shrink)

What behavior is rational? It’s rational to act ethically, some think. Others endorse instrumentalism — it is rational to pursue one’s goals. Still others say that acting rationally always involves promoting one’s self-interest. Many philosophers have given each of these answers. But these answers don’t really conflict; they aren’t vying to describe some shared concept or to solve some mutually acknowledged problem. In so far as this is debated, it is a pseudo-debate. The different uses of ‘ (...) class='Hi'>rational action’ differ merely in meaning. I shall defend the following claims: ‘rational behavior’ is used in ethical, prudential, and instrumental ways (section 1); these uses of ‘rational behavior’ are distinct (section 2); they do not represent competing theories of rational behavior (section 3); we should stop using ‘rational behavior’ ethically and prudentially, but we may continue its instrumental use (section 4).

Following Amartya Sen’s insistence to expand the framework of rational choice theory by taking into account ‘non-utility information,’ economists, political scientists and philosophers have recently concentrated their efforts in analysing the issues related to rights, freedom, diversity intentions and equality. Thomas Boylan and Ruvin Gekker have gathered essays that reflect this trend. The particular themes addressed in this volume include: the measurement of diversity and freedom, formal analysis of individual rights and intentions, judgment aggregation under constraints and strategic manipulation (...) in fuzzy environments. Some papers in the volume also deal with philosophical aspects of normative social choice. (shrink)

I take pseudoscience to be a pretence at science. Pretences are innumerable, limited only by our imagination and credulity. As Stove points out, ‘numerology is actually quite as different from astrology as astrology is from astronomy’ (Stove 1991, 187). We are sure that ‘something has gone appallingly wrong’ (Stove 1991, 180) and yet ‘thoughts…can go wrong in a multiplicity of ways, none of which anyone yet understands’ (Stove 1991, 190). Often all we can do is give a careful description of (...) a way of pretending, a motivation for pretence, a source of pretension. In this chapter I attempt the latter. We will be concerned with the relation of conviction to rational belief. I shall be suggesting that the question of whether an enquiry is a pretence at science can be, in part, a question over the role of conviction in rational belief, and that the answer is to be found in the philosophical problem of the role of values in rational belief.

There has been a long tradition of interpreting Plato as a rational egoist. Over the past few decades, however, some scholars have challenged this reading. While Rational Egoism appeals to many ordinary folk, in sophisticated philosophical circles it has fallen out of favor as a general and complete account of the nature of reasons for action. I argue that while the theory of practical rationality that is often equated with rational egoism—a view that I call ‘Simple-Minded (...) class='Hi'>Rational Egoism'—is neither plausible nor endorsed by Plato in his Republic, there is a more complex version of Rational Egoism to which Plato is indeed committed. Moreover, such a conception of practical rationality is not vulnerable to the standard set of objections that contemporary philosophers have made against Rational Egoism. (shrink)

In this study I discuss G. W. Leibniz's (1646-1716) views on rational decision-making from the standpoint of both God and man. The Divine decision takes place within creation, as God freely chooses the best from an infinite number of possible worlds. While God's choice is based on absolutely certain knowledge, human decisions on practical matters are mostly based on uncertain knowledge. However, in many respects they could be regarded as analogous in more complicated situations. In addition to giving an (...) overview of the divine decision-making and discussing critically the criteria God favours in his choice, I provide an account of Leibniz's views on human deliberation, which includes some new ideas. One of these concerns is the importance of estimating probabilities – in making decisions one estimates both the goodness of the act itself and its consequences as far as the desired good is concerned. Another idea is related to the plurality of goods in complicated decisions and the competition this may provoke. Thirdly, heuristic models are used to sketch situations under deliberation in order to help in making the decision. Combining the views of Marcelo Dascal, Jaakko Hintikka and Simo Knuuttila, I argue that Leibniz applied two kinds of models of rational decision-making to practical controversies, often without explicating the details. The more simple, traditional pair of scales model is best suited to cases in which one has to decide for or against some option, or to distribute goods among parties and strive for a compromise. What may be of more help in more complicated deliberations is the novel vectorial model, which is an instance of the general mathematical doctrine of the calculus of variations. To illustrate this distinction, I discuss some cases in which he apparently applied these models in different kinds of situation. These examples support the view that the models had a systematic value in his theory of practical rationality. (shrink)

If one can get the targets of one's current wants only by acquiring new wants (as in the Prisoner's Dilemma), is it rational to do so? Arguably not. For this could justify adopting unsatisfiable wants, violating the rational duty to maximize one's utility. Further, why cause a want's target if one will not then want it? And people "are" their wants. So if these change, people will not survive to enjoy their wants' targets. I reply that one rationally (...) need not advance one's future wants, only current ones. Furthermore, rational choice seeks not utility (the co-obtaining of a want and its target), but satisfaction (the eventual obtaining of what is now wanted) -- otherwise, it would be irrational to care now about what happens after one dies. Finally, persons survive "rational" changes of values. Thus reflection on the rational revision of values illuminates the conditions on personal identity and the bases and aims of rational choice.

In his book Mind and World, John McDowell grapples with the problem that the world must and yet seemingly cannot constrain our empirical thought. I first argue that McDowell’s proposed solution to the problem throws him onto the horns of his own, intractable dilemma, and thus fails to solve the problem of rational constraint by the world. Next, I will argue that Wilfrid Sellars, in a series of articles written in the 1950s and 60s, provides the tools to solve (...) the dilemma McDowell sets before us. We will see how, borrowing from Sellars and certain neo-Sellarsians, we can solve the problem of rational constraint by perception without resorting to a McDowellian quasi-enchantment of the world.

Leibniz frequently argued that reasons are to be weighed against each other as in a pair of scales, as Professor Marcelo Dascal has shown in his article "The Balance of Reason." In this kind of weighing it is not necessary to reach demonstrative certainty – one need only judge whether the reasons weigh more on behalf of one or the other option However, a different kind of account about rational decision-making can be found in some of Leibniz's writings. In (...) his article "Was Leibniz's Deity an Akrates?" Professor Jaakko Hintikka has argued that Leibniz developed a new vectorial model for rational decisions which is better suited to complicated decisions, where values are complementary to each other. This model, related closely to his work in metaphysics and the philosophy of mind, is a heuristic device which helps in finding rational combinations - and in an ideal case an optimum - between plural inclinations to the good. I shall argue that Leibniz applies more or less implicitly both of these models in his practical rationality. In simple situations he applied the pair of scales model and in more complicated situations he applied the vectorial model. (shrink)

Suppose rationality requires you to A if you believe you ought to A. Suppose you believe that you ought to A. How can you satisfy this requirement? One way seems obvious. You can satisfy this requirement by A-ing. But can you also satisfy it by stopping to believe that you ought to A? Recently, it has been argued that this second option is not a genuine way of satisfying the above requirement. Conditional requirements of rationality do not have two ‘symmetric’, (...) but only one ‘asymmetric’ satisfaction condition. This paper explores the consequences of this argument for a theory of the requirements of rationality. I seek to show that thisview conflicts with another powerful intuition about the requirements of rationality, i.e. ‘rational consistency’: if rationality requires you to X, then it is not the case that rationality requires you to not-X. I shall conclude that ‘asymmetric’ satisfying is based on a misleading intuition, for which we should not sacrifice ‘rational consistency’. (shrink)

In this paper I aim to do two things. First, I attempt to illustrate an interesting pattern of argument one can find in Hume's work. Next, I employ this Humean pattern of argument to show that IF there is a cogent and intuitive argument for any form of epistemological skepticism, which despite its cogency and intuitiveness has a (literally) unbelievable conclusion, THEN we lack a very important form of doxastic self-control, which I call rational self-control (RSC), over the beliefs (...) problematized by that skeptical argument. Thus, (1) the challenge posed by skepticism is even deeper and more radical than commonly supposed: If any form of skepticism proves unanswerable and yet unbelievable, then we demonstrably lack RSC in the domain problematized by that form of skepticism. Thus, (2) one's views on skepticism may entail definite views on (at least one form of) doxastic self-control. (shrink)

Klaas J. Kraay argues that the rational choice model for divine creation—according to which God chooses to actualize one world among possible alternatives based on its axiological properties—cannot succeed given failures of comparability across possible worlds. I argue that failure of comparability across worlds would not undermine the rationality of choosing one world to create among possible alternatives.

We prove that each countable rooted K4 -frame is a d-morphic image of a subspace of the space $\mathbb{Q}$ of rational numbers. From this we derive that each modal logic over K4 axiomatizable by variable-free formulas is the d-logic of a subspace of $\mathbb{Q}$ . It follows that subspaces of $\mathbb{Q}$ give rise to continuum many d-logics over K4 , continuum many of which are neither finitely axiomatizable nor decidable. In addition, we exhibit several families of modal logics finitely (...) axiomatizable by variable-free formulas over K4 that d-define interesting classes of topological spaces. Each of these logics has the finite model property and is decidable. Finally, we introduce quasi-scattered and semi-scattered spaces as generalizations of scattered spaces, develop their basic properties, axiomatize their corresponding modal logics, and show that they also arise as the d-logics of some subspaces of $\mathbb{Q}$.

This paper characterises concisely a key issue about rational justification which highlights an important achievement of Kant’s constructivist method for identifying and justifying basic norms: uniquely, it resolves the Pyrrhonian Dilemma of the Criterion. Kant’s constructivist method is both sound and significant because it is based on core principles of rational justification as such. Explicating this basis of Kant’s constructivism affords an illuminating and defensible explication of four key aspects of the autonomy of rational judgment, including our (...) positive moral freedom; it shows how Kant’s constructivism is fundamentally social and it shows how Kant’s constructivism can readily accommodate historical factors which bear on the appropriateness and legitimacy of social and political institutions. All of these advantages are available without recourse to Kant’s transcendental idealism, and all of them respond to common complaints about or alleged objections to Kant’s practical philosophy.

Suppose you think that whether you believe some proposition A at some future time t might have a causal influence on whether A is true. For instance, maybe you think a woman can read your mind, and either (1) you think she will snap her fingers shortly after t if and only if you believe at t that she will, or (2) you think she will snap her fingers shortly after t if and only if you don't believe at t (...) that she will. Let A be the proposition that she snaps her fingers shortly after t. In case (1), theoretical rationality seems to leave it open whether you should believe A or not. Perhaps, for all it has to say, you could just directly choose whether to believe A. David Velleman seems to be committed to something close to that, but his view has been unpopular. In case (2), you seem to be in a theoretical dilemma, a situation where any attitude you adopt toward A will be self-undermining in a way that makes you irrational. Such theoretical dilemmas ought to be impossible, just as genuine moral dilemmas ought to be impossible, but it is surprisingly hard to show that they are (perhaps because they aren't). I study cases analogous to (1) and (2) in a probabilistic framework where degrees of belief rather than all-or-nothing beliefs are taken as basic. My principal conclusions are that Velleman's view is closer to the truth than it is generally thought to be, that case (2) type theoretical dilemmas only arise for hyperidealised agents unlike ourselves, and that there are related cases that can arise for agents like us that are very disturbing but might not quite amount to theoretical dilemmas.

Weakness of will has been widely discussed from at least three points of view. It has been examined historically, with Aristotle recently occupying centre stage. It has been analysed conceptually, with the question of its nature and possibility in the forefront. It has been considered normatively in relation to both rational action and moral character. My concern is not historical and is only secondarily conceptual: while I hope to clarify what constitutes weakness of will, I presuppose, rather than construct, (...) an account of it. My chief aim is to assess the bearing of weakness of will on the rationality of actions that exhibit it--incontinent actions. Philosophers have tended to assume that incontinent action is a paradigm of irrationality, and none to my knowledge has seriously criticised this assumption. I challenge it and in doing so try to clarify rationality in general. (shrink)

Abstract: The standard picture of rationality requires that the agent acts so as to realize her most preferred alternative in the light of her own desires and beliefs. However, there are circumstances where such an agent can predict that she will act against her preferences. The story of Ulysses and the Sirens is the paradigmatic example of such cases. In those circumstances the orthodoxy requires the agent to be ‘sophisticated’. That is to say, she should take into account her expected (...) future choices and prevent her future self to act in certain ways. She should ‘bind’ herself to a certain course of action. This is a form of causal commitment. It is generally recognized that this form of self-commitment is the only one that is available to a rational agent. Rational commitment, where the agent gives herself a reason to act in a certain way rather than making herself act in that way, is considered not feasible. In this paper, I question this verdict. I sketch the broad outlines of a model of rational commitment, which takes as its starting point Michael Bratman’s ‘planning theory’ of intention. There are two important objections against this theory (one by John Broome and one by the Dutch philosopher Govert den Hartogh.) Both criticisms claim that such a theory is a form of ‘bootstrapping’ reasons for action into existence. In the remainder of the paper, I will defend the theory against these objections. This way, I hope to establish that defending the feasibility of rational commitment is not an obvious mistake. (shrink)

The dominant tradition in Western philosophy sees rationality as dictating. Thus rationality may require that we believe the best explanation and simple conceptual truths and that we infer in accordance with evident rules of inference. I argue that, given what we know about the growth of knowledge, this authoritarian concept of rationality leads to absurdities and should be abandoned. I then outline a libertarian concept of rationality, derived from Popper, which eschews the dictates and which sees a rational agent (...) as one who questions, criticises, conjectures and experiments. I argue that, while the libertarian approach escapes the absurdities of the authoritarian, it requires two significant developments and an important clarification to be made fully consistent with itself.

This essay some first steps toward the naturalization of what I call rational intentionality or alternatively type II intentionality. By rational or type II intentionality, I mean that full combination of rational powers and content-bearing states that is paradigmatically enjoyed by mature intact human beings. The problem I set myself is to determine the extent to which the only currently extant approach to the naturalization of the intentional that has the singular virtue of not being a non-starter (...) can be aggregated up into an account of rational intentionality. I have in mind a broadly defined family of accounts whose main members are the indicator/information-theoretic approach of Dretske (1988), the asymmetric dependence theory of Jerry Fodor (1987, 1990, 1994) and the teleo-semantics of Ruth Millikan (1984, 1993). Somewhat inaccurately, I will call this family of approaches the information-theoretic family. To be sure, there is only a rough family resemblance among the members of the information-theoretic family. Indeed, several intense quarrels divide the members of that family one from another, but the precise outcome of those internecine struggles is not directly relevant to the aims of this essay. ² Taken collectively, the information-theoretic family yields a compelling picture of the place of at least a crude form of intentionality -- what I call frog-like or type I intentionality -- in the natural order. Though frog-like or type I intentionality is, I think, a genuine species of intentionality, it may subsist in the absence of rational powers. It is that species of intentionality enjoyed by irritable creatures who, following Brandom (1994). (shrink)

A discussion of George Bealer's conception and defense of rational intuition as a basis of philosophical knowledge, under three main heads: a) the phenomenology of intellectual intuition; b) the status of such intuition as a basic source of evidence, and the explanation of what gives it that status; and c) the defense of intuition against those who would reject it and exclude it on principle from the set of valid sources of evidence.

This chapter argues that attention is a distinctive mode of consciousness, which plays an essential functional role in making information accessible for use in the rational control of thought and action. The main line of argument can be stated quite simply. Attention is what makes information fully accessible for use in the rational control of thought and action. But what makes information fully accessible for use in the rational control of thought and action is a distinctive mode (...) of consciousness. Therefore, attention is a distinctive mode of consciousness. In a slogan: attention is rational-access consciousness. (shrink)

This paper provides an account of what it is to have faith in a proposition p, in both religious and mundane contexts. It is argued that faith in p doesn’t require adopting a degree of belief that isn’t supported by one’s evidence but rather it requires terminating one’s search for further evidence and acting on the supposition that p. It is then shown, by responding to a formal result due to I.J. Good, that doing so can be rational in (...) a number of circumstances. If expected utility theory is the correct account of practical rationality, then having faith can be both epistemically and practically rational if the costs associated with gathering further evidence or postponing the decision are high. If a more permissive framework is adopted, then having faith can be rational even when there are no costs associated with gathering further evidence. (shrink)

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically (...) class='Hi'>rational in the sense that both are supported by sufficient evidence.

To be rational is to be engaged in collaborative, corrigible, historically informed inquiry and deliberation. Critical intelligence is merely the beginning of rationality. Substantive rationality also requires reflective and imaginative inquiry. Its active exercise presupposes trust and mandates a commitment to the common good, to responsible attempts to create the political institutions and social conditions on which intellectual and political trust can flourish. Without these, formal and calculative intelligence are – however brilliant – mere cleverness; and without these, rationality (...) can undo itself. (shrink)

Most familiar approaches to social conflict moot reasonable ways of dealing with conflict, ways that aim to serve values such as legitimacy, justice, morality, fairness, fidelity to individual preferences, and so on. In this paper, I explore an alternative approach to social conflict that contrasts with the leading approaches of Rawlsians, perfectionists, and social choice theorists. The proposed approach takes intrinsic features of the conflict—what I call a conflict's evaluative 'structure'—as grounds for a rational way of responding to that (...) conflict. Like conflict within a single person, social conflict can have a distinctive evaluative structure that supports certain rational responses over others. I suggest that one common structure in both intra- and interpersonal cases of conflict supports the rational response of 'self-governance'. Self-governance in the case of social conflict involves a society's deliberating over the question, 'What kind of society should we be?' In liberal democracies, this rational response is also a reasonable one. (shrink)

Hume said that the reasons that determine the rationality of one's actions are the desires one has when acting: one's actions are rational iff they advance these desires. Thomas Nagel says this entails calling rational, actions absurdly conflicting in aims over time. For one might have reason, in one's current desires, to begin trying to cause states one foresees having reason, in one's foreseen desires, to prevent. Instead, then, real reasons must be timeless, so that current and foreseen (...) reasons cannot conflict. I say the desire theory does not have absurd consequences. A rational agent's desires would rationally evolve, never requiring actions conflicting in aims over time, except where it was instrumentally rational for her to change in her desires, whence such conflicts are rationally appropriate. Further, whatever sorts of things count as real reasons, since reasons can rationally require their own revision, they cannot be necessarily timeless. (shrink)

Real-world agents do not know all consequences of what they know. But we are reluctant to say that a rational agent can fail to know some trivial consequence of what she knows. Since every consequence of what she knows can be reached via chains of trivial consequences of what she knows, we have a paradox. I argue that the problem cannot be dismissed easily, as some have attempted to do. Rather, a solution must give adequate weight to the normative (...) requirements on rational agents’ epistemic states, without treating those agents as mathematically ideal reasoners. I’ll argue that agents can fail to know trivial consequences of what they know, but never determinately. Such cases are epistemic oversights on behalf of the agent in question, and the facts about epistemic oversights are always indeterminate facts. As a result, we are never in a position to assert that such-and-such constitutes an epistemic oversight for agent i (for we may rationally assert only determinate truths). I then develop formal epistemic models according to which epistemic accessibility relations are vague. Given these models, we can show that epistemic oversights always concern indeterminate cases of knowledge. (shrink)

We are in a state of impending crisis. And the fault lies in part with academia. For two centuries or so, academia has been devoted to the pursuit of knowledge and technological know-how. This has enormously increased our power to act which has, in turn, brought us both all the great benefits of the modern world and the crises we now face. Modern science and technology have made possible modern industry and agriculture, the explosive growth of the world’s population, global (...) warming, modern armaments and the lethal character of modern warfare, destruction of natural habitats and rapid extinction of species, immense inequalities of wealth and power across the globe, pollution of earth, sea and air, even the AIDS epidemic (AIDS being spread by modern travel). All these global problems, involving preventable deaths of millions, have arisen because some of us have acquired unprecedented powers to act without acquiring the capacity to act wisely. We urgently need to bring about a revolution in universities so that the basic intellectual aim becomes, not knowledge merely, but rather to help humanity acquire the capacity to resolve conflicts and problems of living in more cooperatively rational ways. The revolution we need would affect every branch and aspect of academic inquiry. The basic intellectual task of academia would be to articulate our problems of living (personal, social and global) and propose and critically assess possible solutions, possible actions. This would be the task of social inquiry and the humanities. Tackling problems of knowledge would be secondary. Social inquiry would be at the heart of the academic enterprise, intellectually more fundamental than natural science. On a rather more long-term basis, social inquiry would be concerned to help humanity build cooperatively rational methods of problem-solving into the fabric of social and political life, so that we may gradually acquire the capacity to resolve our conflicts and problems of living in more cooperatively rational ways. Natural science would change to include three domains of discussion: evidence, theory, and aims – the latter including discussion of metaphysics, values and politics. Academia would actively seek to educate the public by means of discussion and debate. These changes all come from demanding that academia cure its current damaging structural irrationality, so that reason – the authentic article – may be devoted to promoting human welfare. (shrink)

Some philosophers hold that rational explanations­—explanations of people’s attitudes and actions that cite their reasons for forming these attitudes or performing these actions—are dispositional. The hold that rational explanations do their explanatory work by representing these attitudes and actions as the product of dispositions on the part of the subject. I challenge arguments to this effect by Barry Stroud and Michael Smith. And I argue that human beings do not possess, and could not possess, the dispositions required for (...) the dispositionalist account. I propose an alternative account of rational explanation, one that exploits the connection between rational explanations and rational deliberation to show how such explanations can be simultaneously normative and causal.

Gauthier and Hobbes reduce Prisoners Dilemmas to co-ordination problems (CPs). Many think rational, face-to-face agents can solve any CP by agreed fiat. But though an agent can rationally use a symmetry-breaking technique (ST) to decide between equal options, groups cannot unless their members' STs luckily converge. Failing this, the CP is escapable only by one agent's non-rational stubbornness, or by the group's "conquest" by an outside force. Implications: one's strategic rationality is group-relative; there are some optimums groups in (...) principle cannot rationally choose; thus justice cannot always be a rationally contracted optimum. Howard Sobel provides the point of departure. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of (...) class='Hi'>rational action, and rational decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

If mental anomalism is to be interpreted as a thesisunique to psychology, the anomalousness must begrounded in some feature unique to the mental,presumably its rational nature. While the ground forsuch arguments from normativity has been notoriouslyslippery terrain, there are two recently influentialstrategies which make the argument precise. The firstis to deny the possibility of psychophysical bridgelaws because of the different constitutive essences ofmental and physical laws, and the second is to arguethat mental anomalism follows from the uncodifiabilityof rationality. In (...) this paper I argue that bothstrategies fail – the latter because it conflates primafacie and all things considered rationality and theformer because it rests on a false premise, theprinciple of the rational character of belief. Idistinguish four different formulations of thisprinciple and argue that those formulations which areplausible cannot support the argument for mentalanomalism. (shrink)

The “puzzle of the unmarked clock” derives from a conflict between the following: (1) a plausible principle of epistemic modesty, and (2) “Rational Reflection”, a principle saying how one’s beliefs about what it is rational to believe constrain the rest of one’s beliefs. An independently motivated improvement to Rational Reflection preserves its spirit while resolving the conflict.

Rational agents, it seems, are capable of adopting intentions which make actions rational, which they would otherwise have reason not to do. This paper considers, and rejects, two explanations of this: Constraint Accounts, claiming that adopting such intentions renders one unable to act or to will otherwise; and Indirection accounts, claiming that doing so makes the intended action preferred to its alternatives. I argue that some such explanations are inconsistent with the claim intentions are conduct-controlling pro-attitudes, and others (...) with the claim an action is intentional only if caused and rationalized by some combination of mental states.

Formally-inclined epistemologists often theorize about ideally rational agents--agents who exemplify rational ideals, such as probabilistic coherence, that human beings could never fully realize. This approach can be defended against the well-know worry that abstracting from human cognitive imperfections deprives the approach of interest. But a different worry arises when we ask what an ideal agent should believe about her own cognitive perfection (even an agent who is in fact cognitively perfect might, it would seem, be uncertain of this (...) fact). Consideration of this question reveals an interesting feature of the structure of our epistemic ideals: for agents with limited information, our epistemic ideals turn out to conflict with one another.

After a discussion of several concepts of explanation, in which the criterion of simplicity is emphasized and some interesting historical examples are used as illustration, this paper presents the cosmological and teleological arguments. The central claim is that the hypothesis of theism is more simple and elegant and so more rational than any of its alternatives.

This paper defends a moderate intuitionism by extending a version of that view previously put forward and responding to some significant objections to it that have been posed in recent years. The notion of intuition is clarified, and various kinds of intuition are distinguished and interconnected. These include doxastic intuitions and intuitive seemings. The concept of inference is also clarified. In that light, the possibility of non-inferential intuitive justification is explained in relation to both singular moral judgments, which intuitionists do (...) not take to be self-evident, and basic moral principles, which they typically do take to be self-evident in a sense explicated in the paper. This explanation is accomplished in part by drawing some analogies between moral and perceptual judgments in the light of a developmental conception of knowledge. The final section of the paper presents a partial account of rational disagreement and indicates how the kind of intuitionist view defended can allow for rational disagreement between apparent epistemic peers. (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)

Normativity involves two kinds of relation. On the one hand, there is the relation of being a reason for. This is a relation between a fact and an attitude. On the other hand, there are relations specified by requirements of rationality. These are relations among a person's attitudes, viewed in abstraction from the reasons for them. I ask how the normativity of rationality—the sense in which we ‘ought’ to comply with requirements of rationality—is related to the normativity of reasons—the sense (...) in which we ‘ought’ to have the attitudes what we have conclusive reason to have. The normativity of rationality is not straightforwardly that of reasons, I argue; there are no reasons to comply with rational requirements in general. First, this would lead to ‘bootstrapping’, because, contrary to the claims of John Broome, not all rational requirements have ‘wide scope’. Second, it is unclear what such reasons to be rational might be. Finally, we typically do not, and in many cases could not, treat rational requirements as reasons. Instead, I suggest, rationality is only apparently normative, and the normativity that it appears to have is that of reasons. According to this ‘Transparency Account’, rational requirements govern our responses to our beliefs about reasons. The normative ‘pressure’ that we feel, when rational requirements apply to us, derives from these beliefs: from the reasons that, as it seems to us, we have. (shrink)

Huck Finn's refusal to turn in his friend Jim was not a failure of rationality. It is partly on the basis of such examples that many theorists conclude that the requirements of ethics cannot be the requirements of practical reason. In this essay I will defend rationalism against these worries. But I hope to do more than that. I intend to show how the rationality of people like those described above is compatible with two plausible versions of internalism. Second, I (...) will show how properly formulated rationalism serves to explain these plausible internalist theses along with the plausible cases of rational amorality and immorality which they allow.
The result will be that a plausible internalism and a well-formulated
rationalism are mutually supporting theories. (shrink)

In the first part of this paper I will characterize the specific nature of rational intuition. It will be claimed that rational intuition is an evidential state with modal content that has an a priori source. This claim will be defended against several objections. The second part of the paper deals with the so-called explanationist objection against rational intuition as a justifying source. According to the best reading of this objection, intuition cannot justify any judgment since there (...) is no metaphysical explanation of its reliability. It will be argued that in the case of intuition the very demand of such an explanation is based on a category mistake. (shrink)

Rational agency may be thought of as intentional activity that is guided by the agent's conception of what they have reason to do. The paper identifies and assesses three approaches to this phenomenon, which I call internalism, meta-internalism, and volitionalism. Internalism accounts for rational motivation by appeal to substantive desires of the agent's that are conceived as merely given; I argue that it fails to do full justice to the phenomenon of guidance by one's conception of one's reasons. (...) Meta-internalism explains this phenomenon by postulating higher-order dispositions, consitutive of (rational) agency itself, which causally interact with the agent's normative beliefs to produce corresponding motivations to action. I show that meta-internalism comes to grief over cases of akrasia, insofar as it leaves no room for the capacity for rational guidance when agents voluntarily act at variance with their judgments about what they have reason to do. Volitionalism, I contend, improves on both internalism and meta-internalism. Its distinctive feature is the postulation of a kind of motivation that is directly subject to the agent's control, and independent of the dispositions and desires to which the agent is passively subject.

Regarding certain fictional characters (and situations) F, it is simultaneously true that: (1) We have genuine and rational emotional responses towards F (2) We believe that F is purely fictional At the same time, it is also true that: (3) In order for us to have genuine and rational emotional responses towards a character (or situation), we must not believe that the character (or situation) is purely fictional.

The question I consider is this: The Question: Can two people – who are, and realize they are, intellectually virtuous to about the same degree – both be rational in continuing knowingly to disagree after full disclosure (by each to the other of all the relevant evidence they can think of) while at the same time thinking that the other may well be rational too? I distinguish two kinds of rationality – internal and external – and argue in (...) section 1 that, whichever kind we have in mind, the answer to The Question is ‘yes’ (though that positive answer is less wholehearted in the case of external rationality). Then, in section 2, I briefly make some more general remarks about when discovering a disagreement provides a defeater and when it doesn't. In the final section, I consider an important objection to the answer given in section 1 to The Question. (shrink)

Closure for justification is the claim that thinkers are justified in believing the logical consequences of their justified beliefs, at least when those consequences are competently deduced. Many have found this principle to be very plausible. Even more attractive is the special case of Closure known as Single-Premise Closure. In this paper, I present a challenge to Single-Premise Closure. The challenge is based on the phenomenon of rational self-doubt – it can be rational to be less than fully (...) confident in one's beliefs and patterns of reasoning. In rough outline, the argument is as follows: Consider a thinker who deduces a conclusion from a justified initial premise via an incredibly long sequence of small competent deductions. Surely, such a thinker should suspect that he has made a mistake somewhere. And surely, given this, he should not believe the conclusion of the deduction even though he has a justified belief in the initial premise. (shrink)

Richard Brandt, following Hume, famously argued that suicide could be rational. In this he was going against a common ‘absolutist’ view that suicide is irrational almost by definition. Arguments to the effect that suicide is morally permissible or prohibited tend to follow from one’s position on this first issue of rationality. I want to argue that the concept of rationality is not appropriately ascribed – or withheld – to the victim or the act or the desire to commit the (...) act. To support this, I explore how the concept is ascribed and withheld in ordinary situations, and show that it is essentially future-oriented. Since the suicide victim has no future, it makes no sense to call his act rational or irrational. The more appropriate reaction to a declared desire for suicide, or to the news of a successful suicide, is horror and pity, and these are absent from Brandt’s account, as is a humble acknowledgement of the profound mystery at the heart of any suicide.

In this paper we present an account of practical rationality and weakness of will in terms of rational capacities. We show how our account rectifies various shortcomings in Michael Smith’s related theory. In particular, our account is capable of accommodating cases of weak-willed behaviour that are not ‘akratic’, or otherwise contrary to the agent’s better judgement. Our account differs from Smith’s primarily by incorporating resolve: a third rational capacity for resolute maintenance of one’s intentions. We discuss further two (...) ways to explain the importance of resolve to practical rationality: one based on Richard Holton’s recent work, and an alternative, non-consequentialist account. (shrink)

Niko Kolodny has argued that some (local) rational requirements are narrow-scope requirements. Against this, I argue here that all (local) rational requirements are wide-scope requirements. I present a new objection to the narrow-scope interpretations of the four specific rational requirements which Kolodny considers. His argument for the narrow-scope interpretations of these four requirements rests on a false assumption, that an attitude which puts in place a narrow-scope rational requirement somewhere thereby puts in place a narrow-scope (...) class='Hi'>rational requirement everywhere. My argument against Kolodny is analogous to arguments which use holism about reasons to defend moral particularism. (shrink)

This paper explores the relation between rational authority and social power, proceeding by way of a philosophical genealogy derived from Edward Craig's Knowledge and the State of Nature. The position advocated avoids the errors both of the 'traditionalist' (who regards the socio-political as irrelevant to epistemology) and of the 'reductivist' (who regards reason as just another form of social power). The argument is that a norm of credibility governs epistemic practice in the state of nature, which, when socially manifested, (...) is likely to imitate the structures of social power. A phenomenon of epistemic injustice is explained, and the politicizing implication for epistemology educed. (shrink)

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)

Realists about practical reasons agree that judgments regarding reasons are beliefs. They disagree, however, over the question of how such beliefs motivate rational action. Some adopt a Humean conception of motivation, according to which beliefs about reasons must combine with independently existing desires in order to motivate rational action; others adopt an anti-Humean view, according to which beliefs can motivate rational action in their own right, either directly or by giving rise to a new desire that in (...) turn motivates the action. I argue that the realist who adopts a Humean model for explaining rational action will have a difficult time giving a plausible account of the role that desire plays in this explanation. I explore four interpretations of this role and argue that none allows a Humean theory to explain rational action as convincingly as an anti-Humean theory does. The first two models, in different ways, make acting on a reason impossible. The third allows this possibility, but only by positing a reason-sensitive desire that itself demands an explanation. The fourth avoids this explanatory challenge only by retreating to an empty form of the Humean view. In contrast, an anti-Humean theory can provide an intuitively plausible explanation of rational action. I conclude that the realist about reasons should adopt an anti-Humean theory to explain rational action. (shrink)

In this paper I suggest that near-death experiences (NDEs) provide a rational basis for belief in life after death. My argument is a simple one and is modeled on the argument from religious experience for the existence of God. But unlike the proponents of the argument from religious experience, I stop short of claiming that NDEs prove the existence of life after death. Like the argument from religious experience, however, my argument turns on whether or not there is good (...) reason to believe that NDEs are authentic or veridical. I argue that there is good reason to believe that NDEs are veridical and that therefore it is reasonable to believe in the existence of what they seem to be experiences of, namely, a continued state of consciousness after the death of the body. I will then offer some comments on the philosophical import of NDEs, as well as reflections on the current state of contemporary philosophy in light of the neglect of this phenomenon. (shrink)

The most common argument against the use of rational choice models outside economics is that they make unrealistic assumptions about individual behavior. We argue that whether the falsity of assumptions matters in a given model depends on which factors are explanatorily relevant. Since the explanatory factors may vary from application to application, effective criticism of economic model building should be based on model-specific arguments showing how the result really depends on the false assumptions. However, some modeling results in imperialistic (...) applications are relatively robust with respect to unrealistic assumptions. Key Words: unrealistic assumptions • economics imperialism • rational choice • as if • robustness. (shrink)

Responsibility theorists frequently discuss psychopathy because it challenges various accounts of the capacities required for appropriate ascriptions of moral and legal responsibility. As often described, the psychopath has the capacity to reason practically but lacks the capacity to grasp and control himself in light of moral considerations. As portrayed, then, the psychopath resides in the area of disagreement between two philosophical camps: (i) theorists who put forth the general capacity for practical reasoning or rational self-governance as sufficient for an (...) agent to be appropriately held morally responsible for his conduct; and (ii) theorists who view that general capacity as necessary but not sufficient for moral responsibility, additionally requiring the capacity to grasp and respond to distinctly moral reasons. On the former view, we may appropriately hold psychopaths responsible for their wrongful actions, but not on the latter. This article does not aim to describe the opposing views and argue for one over the other. Rather, I propose to deflate the debate as far as possible, attempting to reduce the area of disagreement. Meaningful disagreement exists only if there are, or could be, agents who have an undiminished capacity for practical reasoning or rational self-governance, yet truly are incapable of moral reasoning. However, I suggest that the capacity for rational self-governance entails the capacity to comprehend and act on moral considerations; thus, to the extent that an individual truly is incapable of grasping moral reasons, we should expect to find deeper, more general deficiencies in that individual's rational capacities. I appeal to the work of leading researchers who study individuals with psychopathy to determine whether psychopaths do represent rational self-governors without the capacity to grasp moral considerations. I argue that this work strongly suggests that the psychopath's incapacity for moral reasoning is, indeed, evidence of more general deficits in the rational capacities required for fully accountable agency. The Article closes with relevant considerations for thinking about any implications for criminal law. (shrink)

Every kind of ‘ought’ implies some kind of ‘can’ – but there are many kinds of ‘ought’ and even more kinds of ‘can’. In this essay, I shall focus on a particular kind of ‘ought’ – specifically, on what I shall call the “rational ‘ought’”. On every occasion of use, this kind of ‘ought’ is focused on the situation of a particular agent at a particular time; but this kind of ‘ought’ is concerned, not with how that agent acts (...) at that time, but with what beliefs or intentions the agent has at the time, or with the sort of reasoning by means of which the agent at that time forms or revises those beliefs or intentions.

Rational intuitions involve a particular form of understanding that gives them a special epistemic status. This form of understanding and its epistemic efficacy are not explained by several current theories of rational intuition, including Phenomenal Conservatism (Huemer, Skepticism and the veil of perception, 2001 ; Ethical intuitionism, 2005 ; Philos Phenomenol Res 74:30–55, 2007 ), Proper Functionalism (Plantinga, Warrant and proper function, 1993 ), the Competency Theory (Bealer Pac Philos Q 81:1–30, 2000 ; Sosa, A virtue epistemology, 2007 (...) ) and the Direct Awareness View (Conee, Philos Phenomenol Res 4:847–857, 1998 ; Bonjour, In defense of pure reason, 1998 ). Some overlook it; others try to account for it but fail. We can account for the role of understanding in rational intuition by returning to the view of some of the early Rationalists, e.g. Descartes and Leibniz. While that view carries a prohibitive cost, it does contain an insight that may help us solve the problem of giving understanding its due. (shrink)

Decision theory comprises, first, a mathematical formalization of the relations among value, belief, and preference; and second, a set of prescriptions for rational preference. Both aspects of the theory are embodied in a single mathematical proof. The problem in the foundations of decision theory is to explain how elements of one and the same proof can serve both functions. I hope to solve this problem in a way that anchors the decision-theoretic norms of rational preference in fundamental intuitions (...) about rationality in general. I will thus depart from the tradition of anchoring those norms in intui-tions about gambling strategies or preference structures of the sort that are the special concern of the theory itself. Although my interpretation is meant to capture what is right about the decision-theoretic conception of rational preference, it will lead me to argue that there is also something fundamentally wrong about that conception. In my view, decision theory tells us how to be rational in our preferences because it tells us how to have preferences that make sense; but there are ways of making sense that outrun, and may in fact conflict with, the prescriptions of decision theory.

This article is another unapologetic contribution to ‘the gentle art of rational choice bashing’. The debate over rational choice theory (RCT) may appear to have tired out; yet RCT is as dominant in political sciences as ever. The reason is that critics typically take aim at the symptoms of RCT’s failings, rather than their root cause: RCT’s very ambition of being the ‘science of choice’. In this article I argue that RCT fails twice, first as a science of (...) choice and then as a science of choice. Both failures suggest that political sciences need an epistemologic (re)conversion away from the Platonic ideal of a deductive and universal science of choice toward a more inductive and pluralist paradigm. While advocates of RCT rightly insist that ‘you can’t beat something with nothing’, I take their advice, with a grain of salt: in order for alternatives to appear, the frame of references needs to be modified. I draw a few perspectives for the political sciences. (shrink)

In the Common Mind, Pettit argues that rational choice theory cannot provide genuine causal accounts of action. A genuine causal explanation of intentional action must track how people actually deliberate to arrive at action. And, deliberation is necessarily enculturated or situated “. . . we take human agents to reason their way to action, using the concepts that are available to them in the currency of their culture” (p. 220). When deciding how to act, “. . . people find (...) their way to action in response to properties that they register in the options before them, properties that are valued in common with others and that can be invoked to provide at least some justification of their choices” (p. 272). That people seek to make justified decisions implies that, at times, their own goals or objectives will be modified in deliberation. Something that rational choice theory cannot allow. (shrink)

In this article I am concerned with whether it could be morally significant to distinguish between doing something 'in order to bring about an effect' as opposed to 'doing something because we will bring about an effect'. For example, the Doctrine of Double Effect (DDE) tells us that we should not act in order to bring about evil, but even if this is true is it perhaps permissible to act only because an evil will thus occur? I discuss these questions (...) in connection with a version of the so-called Trolley Problem known as the Loop Case. I also consider how these questions may bear on whether a rational agent must aim at an event which he believes is causally necessary to achieve an end he pursues. (shrink)

The problem of rational theory-choice is the problem of whether choice of theory by a scientist may be objectively rational in the absence of an invariant scientific method. In this paper I offer a solution to the problem, but the solution I propose may come as something of a surprise. For I wish to argue that the work of the very authors who have put the rationality of such choice in question, Thomas Kuhn and Paul Feyerabend, contains all (...) that is needed to solve the problem.

Galen Strawson has claimed that “the impossibility of free will and ultimate moral responsibility can be proved with complete certainty.” Strawson, I take it, thinks that this conclusion can be established by one argument which he has developed. In this argument, he claims that rational free actions would require an infinite regress of rational choices, which is, of course, impossible for human beings. In my paper, I argue that agent causation theorists need not be worried by Strawson’s argument. (...) For agent causation theorists are able to deny a key principle which drives the regress. Oversimplifying things a bit, the principle states that if one is responsible for her rational actions, then she was antecedently responsible for the reasons on which she acted. (shrink)

Morality and rationality are both normative: the moral claim “you ought to help others” is a genuine normative judgment, as well as the rational maxim “you ought to brush your teeth twice a day”. But it seems that there is a crucial difference these two judgments. In the first part of this paper, I argue that this difference is to be understood as a difference between two kinds of normativity: demanding and recommending normativity. But the crucial task is, of (...) course, to explain the difference. In the second part of this paper, I suggest that metaethical expressivists can provide a good explanation: by extending the analysis of ordinary (non-normative) demands and recommendations to normative judgments, they can formulate a convincing account that captures the key differences between morality and rationality. (shrink)

Is Hume a naturalist? Does he regard all or nearly all beliefs and actions as rationally unjustified? In order to settle these questions, it is necessary to examine their key terms (‘naturalism’ and ‘rational justification’) and to understand the character—especially the normative character—of Hume’s philosophical project. This paper argues (i) that Hume is a naturalist—and, in particular, both a moral and an epistemic naturalist—in quite robust ways; and (ii) that Hume can properly regard many actions and beliefs as “rationally (...) justified” in several different senses of that term. (shrink)

The Uniqueness Thesis, or rational uniqueness, claims that a body of evidence severely constrains one’s doxastic options. In particular, it claims that for any body of evidence E and proposition P, E justifies at most one doxastic attitude toward P. In this paper I defend this formulation of the uniqueness thesis and examine the case for its truth. I begin by clarifying my formulation of the Uniqueness Thesis and examining its close relationship to evidentialism. I proceed to give some (...) motivation for this strong epistemic claim and to defend it from several recent objections in the literature. In particular I look at objections to the Uniqueness Thesis coming from considerations of rational disagreement (can’t reasonable people disagree?), the breadth of doxastic attitudes(can’t what is justified by the evidence encompass more than one doxastic attitude?), borderline cases and caution (can’t it be rational to be cautious and suspend judgment even when the evidence slightly supports belief?), vagueness (doesn’t the vagueness of justification spell trouble for the Uniqueness Thesis?), and degrees of belief (doesn’t a finegrained doxastic picture present additional problems for the Uniqueness Thesis?).

I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is (...) a spandrel/byproduct are themselves rational. (shrink)

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). (...) 3. The rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. -/- How can there be such practices? This paper offers an answer to that question. (shrink)

You are given a choice between two envelopes. You are told, reliably, that each envelope has some money in it—some whole number of dollars, say—and that one envelope contains twice as much money as the other. You don’t know which has the higher amount and which has the lower. You choose one, but are given the opportunity to switch to the other. Here is an argument that it is rationally preferable to switch: Let x be the quantity of money in (...) your chosen envelope. Then the quantity in the other is either 1/2x or 2x, and these possibilities are equally likely. So the expected utility of switching is 1/2(1/2x) + 1/2(2x) = 1.25x, whereas that for sticking is only x. So it is rationally preferable to switch. There is clearly something wrong with this argument. For one thing, it is obvious that neither choice is rationally preferable to the other: it’s a tossup. For another, if you switched on the basis of this reasoning, then the same argument could immediately be given for switching back; and so on, indefinitely. For another, there is a parallel argument for the rational preferability of sticking, in terms of the quantity y in the other envelope. But the problem is to provide an adequate account of how the argument goes wrong. This is the two envelope paradox. In an earlier paper Horgan 2000) I offered a diagnosis of the paradox. I argued that the flaw in the argument is considerably more subtle and interesting than is usually believed, and that an adequate diagnosis reveals important morals about both probability and the foundations of decision theory. One moral is that there is a kind of expected utility, not previously noticed as far as I know, that I call nonstandard expected utility. I proposed a general normative principle governing the proper application of nonstandard expected utility in rational decisionmaking. But this principle is inadequate in several respects, some of which I acknowledged in note added in press and some of which I have meanwhile discovered.. (shrink)

There can be no doubt that Brian Barry has made an enormous contribution to the clarification of the ideas of justice current in contemporary political thought. In Barry’s Justice as Impartiality he explicitly distinguishes and sets in competition three models of justice: justice as mutual advantage; justice as reciprocity; and justice as impartiality (the ‘rational’, ‘fair’ and ‘reasonable’ of my title), and he argues that we should prefer the last of these. What I want to do here is to (...) consider four questions. First, what is this competition a competition about? Second, has Barry adequately characterised the contenders? Third, can the competition be won on the grounds Barry suggests? Fourth, is it a competition that we should want to be won by a single theory? By contrast I want to argue that there are advantages in retaining a pluralist perspective in which all three approaches remain in play. (shrink)

Currently, the most popular views about how to update de se or self-locating beliefs entail the one-third solution to the Sleeping Beauty problem.2 Another widely held view is that an agent‘s credences should be countably additive.3 In what follows, I will argue that there is a deep tension between these two positions. For the assumptions that underlie the one-third solution to the Sleeping Beauty problem entail a more general principle, which I call the Generalized Thirder Principle, and there are situations (...) in which the latter principle and the principle of Countable Additivity cannot be jointly satisfied. The most plausible response to this tension, I argue, is to accept both of these principles, and to maintain that when an agent cannot satisfy them both, she is faced with a rational dilemma.

Creationism is usually regarded as an irrational set of beliefs. In this paper I propose that the best way to understand why individual learners settle on any mature set of beliefs is to see that as the developmental outcome of a series of “fast and frugal” boundedly rational inferences rather than as a rejection of reason. This applies to those whose views are opposed to science in general. A bounded rationality model of belief choices both serves to explain the (...) fact that folk traditions tend to converge on “anti-modernity”, and to act as a default hypothesis, deviations from which we can use to identify other, arational, influences such as social psychological, economic and individual dispositions. I propose some educational and public policy strategies that might decrease the proportion of learners who find creationism and anti-science in general a rational choice. (shrink)

According to one widely held view, a belief is fully justified only if it holds up against the strongest available counterarguments, and we can be appropriately confident that it does hold up only if there is free and open critical discussion of those beliefs between us and our epistemic peers. In this paper I argue that this common picture of ideal rational group inquiry interacts with epistemic problems concerning reasonable disagreement in a way that makes those problems particularly difficult (...) to resolve. By focusing on this idealized context, we get a clearer picture of the epistemic principles at issue. In the end, I argue that the best way to resolve the resulting epistemic conflicts is by appeal to the underdetermination of theory by evidence together with a principle of epistemic conservatism.

Theodor W. Adorno and Jürgen Habermas both champion the goal of a rational society. However, they differ significantly about what this society should look like and how best to achieve it. Exploring the premises shared by both critical theorists, along with their profound disagreements about social conditions today, this book defends Adorno against Habermas' influential criticisms of his account of Western society and prospects for achieving reasonable conditions of human life. The book begins with an overview of these critical (...) theories of Western society. Both Adorno and Habermas follow Georg Lukács when they argue that domination consists in the reifying extension of a calculating, rationalizing form of thought to all areas of human life. Their views about reification are discussed in the second chapter. In chapter three the author explores their conflicting accounts of the historical emergence and development of the type of rationality now prevalent in the West. Since Adorno and Habermas claim to have a critical purchase on reified social life, the critical leverage of their theories is assessed in chapter four. The final chapter deals with their opposing views about what a rational society would look like, as well as their claims about the prospects for establishing such a society. Adorno, Habermas and the Search for a Rational Society will be essential reading for students and researchers of critical theory, political theory and the work of Adorno and Habermas. (shrink)

The study of decision making has multiple implications for business ethics. This paper outlines some commonly used frameworks for understanding choice in business. It characterises the dominant model for business decision making as rational choice theory (RCT) and contrasts this with a more recent, naturalistic theory of decision-making, image theory. The implications of using RCT and image theory to model decision making are discussed with reference to three ethical systems. RCT is shown to be consistent with Utilitarian ethics, but (...) not with Kantian or Virtue-based ethics. Image theory is shown to be consistent with each. The paper identifies a number of implications following from this analysis. (shrink)

Recently, the ‘right to die’ became a major social issue. Few agree suicide is a right tout court . Even those who believe suicide (‘regular’, passive, or physician-assisted) is sometimes morally permissible usually require that a suicide be ‘rational suicide’: instrumentally rational, autonomous, due to stable goals, not due to mental illness, etc. We argue that there are some perfectly ‘rational suicides’ that are, nevertheless, bad mistakes. The concentration on the rationality of the suicide instead of on (...) whether it is a mistake may lead to permitting suicides that should be forbidden. (shrink)

Contemporary discussions of the positive relation between rational choice and moral theory are a special case of a much older tradition that seeks to show that mutual agreement upon certain moral rules works to the mutual advantage, or in the interests, of those who so agree. I make a few remarks about the history of discussions of the connection between morality and self-interest, after which I argue that the modern theory of rational choice can be naturally understood as (...) a continuation of this older tradition. I then go on to argue for a controversial three-fold thesis: (1) that grounding a theory of morality in terms of rational self-interest is the only epistemologically respectable way to proceed with the justification of moral principles; (2) that despite this, most of the contemporary explorations of rational choice foundations for moral principles do not work—that the models of rational choice to which they appeal yield less than the substantial results that they are intended to yield; but (3) that if one rethinks just what it means to be rational, one can find in fact a promising way to connect the two—specifically through the development of a theory of genuinely cooperative activity.

In this essay, I review some results that suggest that rational choice theory has interesting things to say about the virtues. In particular, I argue that rational choice theory can show, first, the role of certain virtues in a game-theoretic analysis of norms. Secondly, that it is useful in the characterization of these virtues. Finally, I discuss how rational choice theory can be brought to bear upon the justification of these virtues by showing how they contribute to (...) a flourishing life. I do this by discussing one particular example of a norm - the requirement that agents to honor their promises of mutual assistance - and one particular virtue, trustworthiness. (shrink)

Non-cognitivism might seem to offer a plausible account of evaluative judgments, at least on the assumption that there is a satisfactory solution to the Frege–Geach problem. However, Cian Dorr has argued that non-cognitivism remains implausible even assuming that the Frege–Geach problem can be solved, on the grounds that non-cognitivism still has to classify some paradigmatically rational inferences as irrational. Dorr’s argument is ingenious and at first glance seems decisive. However, in this paper I will show that Dorr’s argument equivocates (...) between two different notions of evidence , and that once this equivocation is noted there is no reason to doubt that non-cognitivism is consistent with the rationality of such inferences, at least if it is assumed that the Frege–Geach problem can be solved. In particular, I will show that non-cognitivists can endorse the same explanation of the rationality of such inferences that cognitivists should endorse, and that there is thus no need for non-cognitivists to offer any sort of idiosyncratic account of the epistemology of such cases, in contrast to what other commentators on Dorr’s argument have thought.

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly (...) support RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

There is a surprising disconnect between formal rational choice theory and philosophical work on reasons. The one is silent on the role of reasons in rational choices, the other rarely engages with the formal models of decision problems used by social scientists. To bridge this gap, we propose a new, reason-based theory of rational choice. At its core is an account of preference formation, according to which an agent's preferences are determined by his or her motivating reasons, (...) together with a 'weighing relation' between different combinations of reasons. By explaining how someone's preferences may vary with changes in his or her motivating reasons, our theory illuminates the relationship between deliberation about reasons and rational choices. Although primarily positive, the theory can also help us think about how those preferences and choices ought to respond to normative reasons. (shrink)

Because it consists of an entire family of specific theories derived from the same first principles, rational choice offers one approach to generate explanations that provide for micro-macro links, and to attack a wide variety of empirical problems in macrosociology. The aims of this paper are (1) to provide a bare skeleton of all rational choice arguments; (2) to demonstrate their applicability to a range of macrosociological concerns by reviewing a sample of both new and classic works; and (...) (3) to discuss the weaknesses of current rational choice theory and the possibilities for its future development. (shrink)

This article elaborates on foundational issues in the social sciences and their impact on the contemporary theory of belief revision. Recent work in the foundations of economics has focused on the role external social norms play in choice. Amartya Sen has argued in [Sen93] that the traditional rationalizability approach used in the theory of rational choice has serious problems accommodating the role of social norms. Sen’s more recent work [Sen96, Sen97] proposes how one might represent social norms in the (...) theory of choice, and in a very recent article [BS07] Walter Bossert and Kotaro Suzumura develop Sen’s proposal, offering an extension of the classical theory of choice that is capable of dealing with social norms. The first part of this article offers an alternative functional characterization of the extended notion of rationality employed by Bossert and Suzumura in [BS07]. This characterization, unlike the one offered in [BS07], represents a norm-sensitive notion of rationality in terms of a pure functional constraint unmediated by a notion of revealed preference (something that is crucial for the application developed in the second part of this article). This functional characterization is formulated for general domains (as is Bossert and Suzumura’s characterization) and is therefore empirically more applicable than usual characterizations of rationality. Interestingly, the functional constraint we propose is a variant of a condition first entertained in [AGM85] by Carlos Alchourr´on, Peter Gärdenfors and David Makinson in the area of belief change.

Abstract: This paper considers the question of whether it is possible to be mistaken about the content of our first-order intentional states. For proponents of the rational agency model of self-knowledge, such failures might seem very difficult to explain. On this model, the authority of self-knowledge is not based on inference from evidence, but rather originates in our capacity, as rational agents, to shape our beliefs and other intentional states. To believe that one believes that p, on this (...) view, constitutes one's belief that p and so self-knowledge involves a constitutive relation between first- and second-order beliefs. If this is true, it is hard to see how those second-order beliefs could ever be false.I develop two counter-examples which show that despite the constitutive relation between first- and second-order beliefs in standard cases of self-knowledge, it is possible to be mistaken, and even self-deceived, about the content of one's own beliefs. These counter-examples do not show that the rational agency model is mistaken—rather, they show that the possibility of estrangement from one's own mental life means that, even within the rational agency model, it is possible to have false second-order beliefs about the content of one's first-order beliefs. The authority of self-knowledge does not entail that to believe that one believes that p suffices to make it the case that one believes that p. (shrink)

Suicide has been condemned in our culture in one way or another since Augustine offered theological arguments against it in the sixth century. More recently, theological condemnation has given way to the view that suicidal behavior must always be symptomatic of emotional disturbance and mental illness. However, suicide has not always been viewed so negatively. In other times and cultures, it has been held that circumstances might befall a person in which suicide would be a perfectly rational course of (...) action, in the same sense that any other course of action could be rational: that it could be sensible, i.e., defensible by good reasons, or that it could be in keeping with the agent's fundamental interests. Indiscriminate use of modern life-sustaining technologies has renewed interest in the possibility of rational suicide. Today proponents of rational suicide tend to equate the rationality of suicide with the competence of the decision to commit suicide.
