It is a popular view thatpractical deliberation excludes foreknowledge of one's choice. Wolfgang Spohn and Isaac Levi have argued that not even a purely probabilistic self-predictionis available to thedeliberator, if one takes subjective probabilities to be conceptually linked to betting rates. It makes no sense to have a betting rate for an option, for one's willingness to bet on the option depends on the net gain from the bet, in combination with the option's antecedent utility, rather than on the offered (...) odds. And even apart from this consideration, assigning probabilities to the options among which one is choosing is futile since such probabilities could be of no possible use in choice. The paper subjects these arguments to critical examination and suggests that, appearances notwithstanding, practical deliberation need not crowd outself-prediction. (shrink)

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

The rationality of individual agents is secured for the most part by their make-up or design. Some agents, however – in particular, human beings – rely on the intentional exercise of thinking or reasoning in order to promote their rationality further; this is the activity that is classically exemplified in Rodin’s sculpture of Le Penseur. Do group agents have to rely on reasoning in order to maintain a rational profile? Recent results in the theory of judgment aggregation show that under (...) a range of plausible conditions they do. In a slogan: group agents are made, not born. (shrink)

Recently, a cottage industry has formed with the expressed intent of analyzing the nature of personal-level reasoning and inference. The dominant position in the extant philosophical literature is that reasoning consists in rule-governed operations over propositional attitudes. In addition, it is widely assumed that our attitude updating procedures are purely cognitive. Any non-cognitive activity performed in service of updating our attitudes is external to the updating process—at least in terms of rational evaluation. In this paper, I argue that whether one (...) has rationally updated one’s attitudes and whether the resultant attitudes are rational can (at least partially) depend on one’s interactions with one’s environment and body to scaffold one’s ability to arrive at attitudes that are rationally appropriate given one’s evidence.

Why is it important for people to agree on and articulate shared reasons for just laws, rather than whatever reasons they personally find compelling? What, if any, practical role does public reason play in liberal democratic politics? We argue that the practical role of public reason can be better appreciated by examining the confluence of normative and positive political theory; the former represented here by liberal social contract theory of John Rawls and others, and the latter by rational choice or (...) game theory. Citizens in a diverse society face a practical as well as a moral problem. How can they have confidence that others will reciprocate their commitment to supporting governing principles that depart from their own ideal conceptions of truth and value in order to be reasonable to all? Citizens face a practical problem of mutual assurance that public reason helps them solve, and solve as a matter of common knowledge. The solution, on both views, requires citizens’ reciprocal commitment to basing law on a system of shared reasons. Both views place public reason at the core of liberal democratic politics in conditions of diversity, and for quite similar reasons. Our argument illustrates the complementary roles of positive and values-based analysis in constitutional design. (shrink)

This article gives an overview of some recent debates about the relationship between reasons and rational requirements of coherence - e.g. the requirements to be consistent in our beliefs and intentions, and to intend what we take to be the necessary means to our ends.

H.-J. Glock has made important contributions to discussions of rationality, reasons, and rules. This chapter addresses four conceptions of rationality that Glock identifies. One of these conceptions of rationality is that rationality consists in responsiveness to reasons. This chapter goes on to consider the idea that reasons became prominent in normative ethics because of their usefulness in articulating moral pluralism. The final section of the chapter connects reasons and rules and contends that both are ineliminable.

The paper provides a critical discussion of some key aspects of John Broome’s theories of rationality, reasoning and the relations between them.

In this paper, I present a brief (and more than a little potted) history of the concepts of reason, rationality, reasonableness, and reasons in modern European philosophy and consider whether this history might support the "Anscombean" conclusion that, "The concepts of rationality and reasons ought to jettisoned if this is psychologically possible; because they are survivals, or derivatives from survivals, from an earlier conception of psychology and philosophy which no longer generally survives, and are only harmful without it.".

Nonmonotonic reasoning is a discipline of computer science, epistemology, and cognition: It models inferences where classical logic is inadequate in symbolic AI, defines normative models for reasoning with defeasible information in epistemology, and models human reasoning under information change in cognition. Its building blocks are defeasible rules formalised as DeFinetti conditionals. In this thesis, Christian Eichhorn examines qualitative and semi-quantitative inference relations on top said conditionals, using the conditional structure of the knowledge base and Spohn’s Ordinal Conditional Functions, using established (...) properties. Converting network approaches from probabilistics, he shows how to approach the relations with regard to implementation. (shrink)

How do Goya's representations of the body disrupt the Enlightenment's configurations of the corporeal? If for eighteenth-century aesthetics the body is both the site of ideal beauty and the limit of what can and may be represented, then Goya's panoply of monsters provides a way of understanding other modes of reason, other ways of representing the body and its functions within culture. In his work there is a recuperation of those elements that seem to lie outside the ken of the (...) Enlightenment project: physicality, animality, hybridity, the grotesque, the popular; a recognition of the animal nature of the body and the products of bodily impulses and forces. A rethinking of the body would incorporate an understanding of its role as a physical and social phenomenon in the constitution of the subject. Following on from Paul Ilie's concept of counter-rational Reason, which he defines as the opposite of a uniform centre of rationality in representative thought, the first half of my paper will consider Goya's problematization of representation. My analysis of a selection of drawings from the collection Los Caprichos will focus not just on the representation of bodies in the painter's work but on his exploration of bodies in their material variety—configurations of modes of constructing the body. This examination of Goya's prolific pictorial negotiations and adaptations of flesh and world will draw upon contemporary approaches to theorizing the body, namely the theories of Julia Kristeva and Elizabeth Grosz.

Ecological rationality is a concept important to most environmental and natural resources policy and to much policy-relevant literature and research. Yet ecological rationality as a distinctive form of reason can only be understood and appreciated in the context of a larger body of work on the general concept of rationality. In particular, Herbert Simon’s differentiation between substantive and proceduralrationality and Paul Diesing’s specification of forms of practical reason are useful tools in mapping and defining ecological rationality. The significance and characteristics (...) of ecological rationality suggest that it is a fundamental kind of reason, having precedence over others. (shrink)

Rationality and reason are often used as synonyms, although they are very different concepts. In this article we argue that rationality is the concept of reason that has been stripped of its human elements. Ancient and medieval philosophers such as Aristotle and Aquinas stressed that the concept of reason is composed of sensitive, discursive, and moral elements. Post-Enlightenment thinkers instead, building on the works of René Descartes and Isaac Newton, took these out and claimed that rationality must be based on (...) an external logic devoid of value-concepts such as perfection, harmony, meaning and aim (Koyré in From the closed world to the infinite universe, The Johns Hopkins University Press, Baltimore, 1957). The purpose of this essay is to highlight this shift in Western thought and its consequences for management theories. While explaining the ancient concept of reason in contrast with modern rationalism (Klein in: Williamson RB, Zuckerman E (eds) Jacob Klein—lectures and essays, St. John’s College Press, Annapolis, 1985), we aim at raising awareness of the differences between building a research programme (especially in business sciences like economics and management) on rationality or on reason.

Philosophers over the course of the last century, including Edmund Husserl, Chaim Perelman, and Jacques Derrida, have attempted to unravel the tangled relationship between the rational and the reasonable in order to understand how the history of thought progresses. Critical political theorists, including Michel Foucault and Ernesto Laclau have also investigated this issue from a range of perspectives, especially as it relates to the relationship between ideational limits and their transgression and the universal and the particular. This essay compares these (...) perspectives to locate the rational dimensions of the reasonable, and to relate that “meta-reason” to the irrational and unreasonable aspects of identity formation and the unfolding of world history.

Perelman’s discussion about the distinction and relation between the rational and the reason-able could be seen as an attempt to bring forward a new understanding of rationality. In light of the concep-tion of situated reason, this paper argues that Perelman’s explication of the dialectic of the rational and the reasonable highlights the balance of universality and contexuality, and could contribute a fuller conception of rationality to establishing a solid philosophical foundation for Johnson’s informal logic.

A major virtue of the Pragma-Dialectical theory of argumentation is its commitment to reasonableness and rationality as central criteria of argumentative quality. However, the account of these key notions offered by the originators of this theory, Frans van Eemeren and Rob Grootendorst, seems to us problematic in several respects. In what follows we criticize that account and suggest an alternative, offered elsewhere, that seems to us to be both independently preferable and more in keeping with the epistemic approach to arguments (...) and argumentation we favor.

We present a unified approach for investigating rational reasoning about basic argument forms involving indicative conditionals, counterfactuals, and basic quantified statements within coherence-based probability logic. After introducing the rationality framework, we present an interactive view on the relation between normative and empirical work. Then, we report a new experiment which shows that people interpret indicative conditionals and counterfactuals by coherent conditional probability assertions and negate conditionals by negating their consequents. The data support the conditional probability interpretation of conditionals and the (...) narrow-scope reading of the negation of conditionals. Finally, we argue that coherent conditional probabilities are important for probabilistic analyses of conditionals, nonmonotonic reasoning, quantified statements, and paradoxes. (shrink)

A collection of essays by contemporary Calvinist philosophers of religion that examine the epistemology of religious belief between Reformed and Roman Catholic philosophers.

This paper presents a philosophical critique of intuitionism and other current theories of rationality that underlie and, in some cases, question the cogency of codes of ethics. A classical theory of rationality is defended and a concept of ‘reasonableness’ is developed as an ideal-type in setting out the principles for an effective ethical education that can form the basis for implementing a code of conduct.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Sovereignty of Reason: The Defense of Rationality in the Early English Enlightenment by Frederick C. BeiserJohn W. YoltonFrederick C. Beiser. The Sovereignty of Reason: The Defense of Rationality in the Early English Enlightenment. Princeton: Princeton University Press, 1996. Pp. xi + 332. Cloth, $39.50.Beiser characterizes the methodology of his study as historical and philosophical: historical in placing texts in their own context and in uncovering the intentions (...) of their authors; philosophical in reconstructing and appraising arguments (ix). Both methods are necessary for good historical work. The second is often practiced without the first, to the detriment of philosophy and its history. “A philosopher who reconstructs arguments without the aid of history indulges in mere guesswork and anachronism, measuring the standards of philosophical relevance and importance by the concerns of his own age” (x). Equally, understanding the arguments and ideas of, e.g., seventeenth-century writers, “also involves testing their truth: seeing how they cohere with one another, what their consequences are, whether they follow from the evidence adduced for them, and if they reply to the objections made against them” (x). This splendid study of the role of reason in seventeenth-century religion, science, and philosophy is a fine example of careful textual-historical scholarship with rigorous philosophical analysis.The goal of his study is to tell “the story of how rationalism, in the very specific sense of the sovereignty of reason, arose in seventeenth-century England” (5). Starting with an introduction which discusses such topics as “The Paradox of the English Enlightenment,” “Rationalism in the English Church,” “The Enlightenment and the New Sciences,” Beiser proceeds to detailed presentations and discussions of “The Protestant Challenge” (Chap. 1); Richard Hookers’s defense of reason (Chap. 2); the views of the Great Tew Circle, e.g., Falkland, Chillingworth, Hammond, Hales (Chap. 3); the Cambridge Platonists (Chap. 4); the nature of Enthusiasm (Chap. 5); John Toland and Deism (Chap. 6); and ethical rationalism (Chap. 7).Many of the topics covered have been the subjects of other books and articles. What marks Beiser’s account is the freshness of his approach, the many new insights and suggestions about the tensions between the holders of traditional doctrines and newer challenges. Beiser’s writing is clear, and the issues are carefully presented and analyzed. One of the central themes is the mistake of equating “rationalism with the critique or rejection of religion” (15), of identifying enlightenment with secularization (14). The appeals to reason often emerge from within orthodox religion, whose defenders were trying to cope with their own internal tensions. “Once we consider the Cambridge Platonists’ early reaction to predestination, it becomes clear that it was not Hobbes but Calvin who first posed the danger of atheism for them. For it was Calvin’s theology, and not Hobbes’s materialism, that inspired the fear of God that [End Page 138] they regarded as the source of atheism. In the eyes of the Cambridge Platonists, Hobbes’s materialism was only a false remedy for that fear...” (147). A similar point is made later: “the foundations of a rational theology” in Whichcote “did not arise from any need to combat a creeping Hobbesianism. Rather, it grew up from the inner struggles and torments of the Protestant soul” (165).Equally significant is Beiser’s analysis of enthusiasm, the appeals to divine inspiration rather than to reason or evidence: “We should be aware of accepting the contemporary caricature of the enthusiasts, which portrayed them as zealous and ignorant anti–intellectuals with no cogent or coherent philosophical position of their own” (187). His analysis of the enthusiasts stresses the epistemological nature of their position, rather than the usual theological, ethical, or political dimensions (193). He insists that “enthusiasm is essentially a philosophical concept. Historically, it arose as a response to the problem of the sources and criteria of religious knowledge” (187). The search for criteria is a pervasive feature of Beiser’s study: Luther’s and Calvin’s efforts to draw the boundary between faith and reason (24); Richard Hooker’s failure to “provide an epistemological foundation for his theory of natural law” (67); the need for a criterion to distinguish genuine from false revelation...

The slogan that rationality is about responding to reasons has a turbulent history: once taken for granted; then widely rejected; now enjoying a resurgence. The slogan is made harder to assess by an ever-increasing plethora of distinctions pertaining to reasons and rationality. Here we are occupied with two such distinctions: that between subjective and objective reasons, and that between structural rationality (a.k.a. coherence) and substantive rationality (a.k.a. reasonableness). Our paper has two main aims. The first is to defend dualism about (...) rationality – the view that affirms a deep distinction between structural and substantive rationality – against its monistic competitors. The second aim is to answer the question: with the two distinctions drawn, what becomes of the slogan that rationality is about responding to reasons? We’ll argue that structural rationality cannot be identified with responsiveness to any kind of reasons. As for substantive rationality, we join others in thinking that the most promising reasons-responsiveness account of substantive rationality will involve an “evidence-relative” understanding of reasons. But we also pose a challenge for making this idea precise – a challenge that ultimately calls into question the fundamentality of the notion of a reason even with respect to the analysis of substantive rationality.

Whereas Bayesians have proposed norms such as probabilism, which requires immediate and permanent certainty in all logical truths, I propose a framework on which credences, including credences in logical truths, are rational because they are based on reasoning that follows plausible rules for the adoption of credences. I argue that my proposed framework has many virtues. In particular, it resolves the problem of logical omniscience.

The demands of rationality are linked both to our subjective normative perspective (given that rationality is a person-level concept) and to objective reasons or favoring relations (given that rationality is non-contingently authoritative for us). In this paper, I propose a new way of reconciling the tension between these two aspects: roughly, what rationality requires of us is having the attitudes that correspond to our take on reasons in the light of our evidence, but only if it is competent. I show (...) how this view can account for structural rationality on the assumption that intentions and beliefs as such involve competent perceptions of downstream reasons, and explore various implications of the account.

What kind of thing is a reason for action? What is it to act for a reason? And what is the connection between acting for a reason and rationality? There is controversy about the many issues raised by these questions. In this paper I shall answer the first question with a conception of practical reasons that I call ‘Factualism’, which says that all reasons are facts. I defend this conception against its main rival, Psychologism, which says that practical reasons are (...) mental states or mental facts, and also against a variant of Factualism that says that some practical reasons are facts and others are false beliefs. I argue that the conception of practical reasons defended here provides plausible answers to the second and third questions above; and gives a more unified and satisfactory picture of practical reasons than those offered by its rivals.

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)

John Broome argues that rationality cannot consist in reasons-responsiveness since rationality supervenes on the mind, while reasons-responsiveness does not supervene on the mind. I here defend this conception of rationality by way of defending the assumption that reasons-responsiveness supervenes on the mind. Given the many advantages of an analysis of rationality in terms of reasons-responsiveness, and in light of independent considerations in favour of the view that reasons-responsiveness supervenes on the mind, we should take seriously the backup view, a hypothesis (...) that explains why reasons-responsiveness supervenes on the mind even though paradigmatic reasons are external facts. I argue that Broome’s objections to the backup view, as well as his more general objection to the thesis that reasons-responsiveness supervenes on the mind, do not succeed. (shrink)

A discussion of epistemic reasons, theoretical rationality, and the relationship between them.

Are people rational? This question was central to Greek thought and has been at the heart of psychology and philosophy for millennia. This book provides a radical and controversial reappraisal of conventional wisdom in the psychology of reasoning, proposing that the Western conception of the mind as a logical system is flawed at the very outset. It argues that cognition should be understood in terms of probability theory, the calculus of uncertain reasoning, rather than in terms of logic, the calculus (...) of certain reasoning. (shrink)

This paper explicates an account of argumentative rationality by articulating the common, basic idea of its nature, and then identifying a collection of assumptions inherent in it. Argumentative rationality is then contrasted with dual-process theories of reasoning and rationality prevalent in the psychology of reasoning. It is argued that argumentative rationality properly corresponds only with system-2 reasoning in dual-process theories. This result challenges the prescriptive force of argumentative norms derives if they derive at all from their descriptive accuracy of our (...) cognitive capacities. In response, I propose an activity-based account of reasoning which retains the assumptions of argumentative rationality while recontextualizing the relationship between reasoning as a justificatory activity and the psychological states and processes underlying that activity.

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

Humans and animals make inferences about the world under limited time and knowledge. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might. Following H. Simon's notion of satisficing, the authors have proposed a family of algorithms based on a simple psychological mechanism: one-reason decision making. These fast and frugal algorithms violate fundamental tenets of classical rationality: They neither look up nor integrate all information. By computer simulation, the (...) authors held a competition between the satisficing "Take The Best" algorithm and various "rational" inference procedures. The Take The Best algorithm matched or outperformed all competitors in inferential speed and accuracy. This result is an existence proof that cognitive mechanisms capable of successful performance in the real world do not need to satisfy the classical norms of rational inference. (shrink)

Contending that only a normative theory of rationality can be adequate to the complexities of the subject, this book explains and defends the view that rationality consists of the intelligent pursuit of appropriate objectives. Rescher considers the mechanics, rationale, and rewards of reason, and argues that social scientists who want to present a theory of rationality while avoiding the vexing complexities of normative deliberations must amend their perspective of the rational enterprise.

Brian Hedden defends a radical view about the relationship between rationality, personal identity, and time. On the standard view, personal identity over time plays a central role in thinking about rationality, because there are rational norms for how a person's attitudes and actions at one time should fit with her attitudes and actions at other times. But these norms are problematic. They make what you rationally ought to believe or do depend on facts about your past that aren't part of (...) your current perspective on the world, and they make rationality depend on controversial, murky metaphysical facts about what binds different instantaneous snapshots into a single person extended in time. Hedden takes a different approach, treating the relationship between different time-slices of the same person as no different from the relationship between different people. On his account, the locus of rationality is the time-slice rather than the temporally extended agent. This impersonal, time-slice-centric approach to rationality yields a unified approach to the rationality of beliefs, preferences, and actions where what rationality demands of you is solely determined by your evidence, with no special weight given to your past beliefs or actions.

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