Practical and Theoretical Reasoning

Philosophers of action of different persuasions have suggested that there is a tight connection between the phenomenon of intending and the phenomena of “being settled on” and of “settling” a course of action. For many, this connection supports an important constraint on intention: one may only intend what one takes one’s so intending as settling. Traditionally, this has been understood as a doxastic constraint on intention: what one takes one’s intention as settling is what one believes one’s so intending as (...) settling. This paper proposes an alternative conception of such a constraint. The idea is to conceive of it in terms of the attitude of reliance, rather than of belief. The aim of the paper is three-fold: to clarify the connection between intending to act and the phenomena of being settled on and of settling a course of action, to provide support for the reliance conception of the cited constraint, and to show that this conception drives a wedge in the familiar dispute, between doxastic and conative accounts of intention, as to whether intending to act necessarily involves the belief that one will so act.

Philosophers have in general offered only a partial view of the normative grounds of reliance. Some maintain that either one of evidence or of pragmatic considerations has a normative bearing on reliance, but are silent about whether the other kind of consideration has such a bearing on it as well. Others assert that both kinds of considerations have a normative bearing on reliance, but sidestep the question of what their relative normative bearing is. My aim in this article is to (...) offer a more systematic and comprehensive view of reasons for reliance. (shrink)

In this article I attempt to provide a conceptual framework for thinking about reliance in a systematic way. I argue that reliance is a cognitive attitude that has a tighter connection to the guidance of our thought and action than ordinary belief does. My main thesis is that reliance has a ‘constitutive aim’: namely, it aims at guiding our thought and action in a way that is sensible from the standpoint of practical or theoretical ends. This helps explain why reliance (...) is, in contrast to belief, typically formed and revised in response to pragmatic considerations. (shrink)

It is widely held that instrumental reasoning to a practical conclusion is parasitic on non-instrumental practical reasoning. This conclusion is based on the claim that when there is no reason to adopt a certain end, there is no reason to take the means (qua means) to that end. But, as will be argued, while there is a sense of reason according to which the previous statement is true, there is another sense according to which it is false. Furthermore, in both (...) of the relevant senses of reason, it is true that reasons are considerations that ground correct conclusions of practical deliberation and correct advice. It follows that instrumental reasoning to a practical conclusion is not invariably parasitic on non-instrumental practical reasoning. The view that it is results from combining the idea that when there is no reason to adopt a certain end, there is no reason to take the means (qua means) to that end, with the common but faulty assumption that considerations that ground correct conclusions of practical deliberation and correct advice are all reasons in a single sense (sometimes referred to as the normative sense of reason). The assumption in question is implicit in, for example, the work of John Broome, T. M. Scanlon, Christine Korsgaard, and Stephen Darwall.1 Given the common identification of normative reasons with considerations that ground correct conclusions of practical deliberation and correct advice, the position that will be defended in this paper can be expressed by saying that there is not one but two senses of reason for which it is true that reasons are normative..

Action theorists and formal epistemologists often pursue parallel inquiries regarding rationality, with the former focused on practical rationality, and the latter focused on theoretical rationality. In both fields, there is currently a strong interest in exploring rationality in relation to time. This exploration raises questions about the rationality of certain patterns over time. For example, it raises questions about the rational permissibility of certain patterns of intention; similarly, it raises questions about the rational permissibility of certain patterns of belief. While (...) the action-theoretic and epistemic questions raised are closely related, advances in one field are not always processed by the other. This volume brings together contributions by scholars in action theory and formal epistemology working on questions regarding rationality and time so that researchers in these overlapping fields can profit from each other’s insights. This book was originally published as a special issue of the _Canadian Journal of Philosophy. _. (shrink)

This is a welcome reprint of a book that continues to grow in importance.

The literature on theoretical reason has been dominated by epistemological concerns, treatments of practical reason by ethical concerns. This book overcomes the limitations of dealing with each separately. It sets out a comprehensive theory of rationality applicable to both practical and theoretical reason. In both domains, Audi explains how experience grounds rationality, delineates the structure of central elements, and attacks the egocentric conception of rationality. He establishes the rationality of altruism and thereby supports major moral principles. The concluding part describes (...) the pluralism and relativity his conception of rationality accommodates and, taking the unified account of theoretical and practical rationality in that light, constructs a theory of global rationality--the overall rationality of persons. Rich in narrative examples, intriguing analogies, and intuitively appealing arguments, this beautifully crafted book will spur advances in ethics and epistemology as well in philosophy of mind and action and the theory of rationality itself.

Joseph Raz and Sergio Tenenbaum argue that the Guise of the Good thesis explains both the possibility of practical reason and its unity with theoretical reason, something Humean psychological theories may be unable to do. This paper will argue, however, that Raz and Tenenbaum face a dilemma: either the version of the Guise of the Good they offer is too strong to allow for weakness of will, or it will lose its theoretical advantage in preserving the unity of reason.

This paper argues that, with certain provisos, predicting one's future actions is incompatible with rationally deliberating about whether to perform those actions. It follows that fully rational omniscient agents are impossible, since an omniscient being could never rationally deliberate about what to do . Consequently, theories that explain practical reasons in terms of the choices of a perfectly rational omniscient agent must fail. The paper considers several ways of defending the possibility of an omniscient agent, and concludes that while some (...) of these may work, they are inconsistent with the aim of explaining practical normativity by appeal to such an agent.

‘…one might easily wonder why no one has ever pointed out the mince pie syllogism…” (G. E. M. Anscombe, Intention, 2nd edition 1969, sec. 33).

This paper develops some of Austin’s ideas on excuses, stressing their “dimensional” character and relating it to Searle’s distinction between intention-in-action and previous intention, in order to show that the original speech-act shaped distinction between weakness of the will and moral weakness can be embedded in a quite different theoretical framework such as Davidson’s, while Austin’s dimensional classification of actions cannot. Finally, the article analyzes how Grice’s critique of Davidson’s views on akrasia is more faithful to Austin and more radical (...) in its conclusions concerning the justificatory aspect of reasons and the rational features of action.

In this essay, we explore an issue of moral uncertainty: what we are permitted to do when we are unsure about which moral principles are correct. We develop a novel approach to this issue that incorporates important insights from previous work on moral uncertainty, while avoiding some of the difficulties that beset existing alternative approaches. Our approach is based on evaluating and choosing between option sets rather than particular conduct options. We show how our approach is particularly well-suited to address (...) this issue of moral uncertainty with respect to agents that have credence in moral theories that are not fully consequentialist.

Is knowledge necessary or sufficient or both necessary and sufficient for acceptable practical reasoning and rational action? Several authors (e.g., Williamson, Hawthorne, and Stanley) have recently argued that the answer to these questions is positive. In this paper I present several objections against this view (both in its basic form as well in more developed forms). I also offer a sketch of an alternative view: What matters for the acceptability of practical reasoning in at least many cases (and in all (...) the cases discussed by the defenders of a strong link between knowledge and practical reasoning) is not so much knowledge but expected utility.

Practical conflicts pervade human life. Agents have many different desires, goals, and commitments, all of which can come into conflict with each other. How can practical reasoning help to resolve these practical conflicts? In this collection of essays a distinguished roster of philosophers analyse the diverse forms of practical conflict. Their aim is to establish an understanding of the sources of these conflicts, to investigate the challenge they pose to an adequate conception of practical reasoning, and to assess the degree (...) to which that challenge can be met. These essays will serve as a major resource for students of philosophy but will also interest students and professionals in related fields of the social sciences such as psychology, political science, sociology and economics.

This paper concerns connection between knowing or accepting a logical principle such as Modus Ponens and actions of reasoning involving it. Discussions of this connection typically mention the so-called ‘Lewis Carroll Regress’ and there is near consensus that the regress shows something important about it. Also, although the regress explicitly concerns logic, many philosophers think that it establishes a more general truth, about the structurally similar connection between epistemic or practical principles and actions involving them. This paper’s first aim is (...) to address key interpretations Carroll’s regress as clearly as possible so as to show precisely how it might be relevant to questions concerning the connection between logical knowledge and reasoning, and, more broadly, to discussions of how epistemic or practical principles may be action-guiding. Its second aim is to show that the regress fails to establish anything of substance about the connection between logical knowledge and reasoning, or any other structurally similar relation, unless substantive, contentious and typically undefended assumptions are made. The consensus is thus on shaky ground. (shrink)

Holton, we acknowledge, has given a good counter-example to a theory, and that theory is interesting and worth refuting. The theory we have in mind is like Smith's, but is more reductionist in spirit. It is a theory that ties value to Reason and to processes of reasoning, or inference - not to the recognition of reasons and acting on reasons. Such a theory overestimates the importance of logic, truth, inference, and thinking things through for yourself independently of any ideas (...) about where you might end up. Now it might well be thought that any Kantian theory of value would need to be tied to just such a conception of Reason. But while the theory behind The Moral Problem is Kantian in some very salient respects, the survival of Smith's analysis of value in the face of Holton's argument is very instructive. It teaches us a memorable moral: that a Kantian theory like Smith' s does not need to be tied - even loosely - to an overly intellectualised, logocentric conception of Reason. (shrink)

Akrasia is both an intentional and an irrational phenomenon. These two characteristics can be reconciled by a careful reconstruction of practical reasoning. I undertake this task along Davidsonian lines, arguing against his critics that the notion of unconditional judgment is the key to an adequate account of akrasia. Unless akrasia is conceived as a failure of the agent to form an unconditional judgment that conforms to her best judgment "all things considered," the intentionality of akrasia is lost. Likewise, I show (...) how practical and theoretical reasoning concur in the production of action, and why akrasia is a problem for the philosophy of action before being a problem for moral philosophy.

Cet article se propose de montrer que l’éthique de la croyance, si elle permet de clarifier certains problèmes épistémiques, a le tort d’être utilisée à des fins pour lesquelles le réseau conceptuel de l’éthique est inadéquat.

J’indique ensuite pourquoi ces arguments ne sont pas concluants en examinant de plus près les rapports existant entre raisons épistémiques et raisons pratiques.

This paper proposes a concept of "valid reasoning" that will apply univocally to reasoned judgment (inference), Reasoned decision (choice), And reasoned withholding of judgment and decision. "reasoning" is taken to include all these; "validity" of reasoning is defined in terms of the "ideally rational mind", Which is in turn defined by a modal logic of judging and deciding. The definition is defended by relating it to another ideal, That of the socratically omniscient and stoically omniscient sage, Who is defined by (...) a modal logic of knowing and doing. In the course of this I distinguish between the vehicle and the description of a mental act, Deny that reasoning is a transition, Analyze doing as causing to be, And maintain that, Since doing stands to deciding as knowing stands to judging, Reasoned decision is genuinely practical reasoning.

The author states that it has been a common conviction among philosophers, And still is, That there is an important difference between practical matters and theoretical matters; between answers to such practical questions as 'what is to be done?' and answers to such theoretical questions as 'what is the case?' this distinction has sometimes been thought to be such that though reason can be theoretical there is an important sense in which it cannot be practical. The author maintains that one (...) influential idea might be put vaguely like this: reason is non-Substantive in such a way that unlike theories, Actions, Being events, Are not accessible to it. It is this idea, And its associated view of the practical-Theoretical distinction it is based on, That edgley considers. (staff). (shrink)

Two approaches to instrumental rationality Suppose I intend end E, believe that a necessary means to E is M, and believe that M requires that I intend M. My attitudes concerning E and M engage a basic requirement of practical rationality, a requirement that, barring a change in my cited beliefs, I either intend M or give up intending E.2 Call this the Instrumental Rationality requirement – for short, the IR requirement.

Suppose you resolve now to resist an expected temptation later while knowing that once the temptation arrives your preference or evaluative assessment will shift in favor of that temptation. Are there defensible norms of rational planning agency that support sticking with your prior intention in the face of such a shift at the time of temptation and in the absence of relevant new information? This article defends the idea that it might be rational to stick with your prior intention in (...) part because of your anticipation of regret in the further future if you were to give in to the temptation. It does this by appeal to the significance of anticipated future regret to the agent ’s present standpoint, and to the role of the agent ’s standpoint in her self-governance. (shrink)

Normative requirements are often overlooked, but they are central features of the normative world. Rationality is often thought to consist in acting for reasons, but following normative requirements is also a major part of rationality. In particular, correct reasoning – both theoretical and practical – is governed by normative requirements rather than by reasons. This article explains the nature of normative requirements, and gives examples of their importance. It also describes mistakes that philosophers have made as a result of confusing (...) normative requirements with reasons. (shrink)

It has become recently popular to suggest that knowledge is the epistemic norm of practical reasoning and that this provides an important constraint on the correct account of knowledge, one which favours subject-sensitive invariantism over contextualism and classic invariantism. I argue that there are putative counterexamples to both directions of the knowledge norm. Even if the knowledge norm can be defended against these counterexamples, I argue that it is a delicate issue whether it is true, one which relies on fine (...) distinctions among a variety of relevant notions of propriety which our intuitions may reflect. These notions variously apply to the agent herself, her character traits, her beliefs, her reasoning and any resultant action. Given the delicacy of these issues, I argue that the knowledge norm is not a fixed point from which to defend substantive and controversial views in epistemology. Rather, these views need to be defended on other grounds. (shrink)

While the causal contributions of so-called ‘automatic’ processes to behavior are now widely acknowledged, less attention has been given to their normative role in the guidance of action. We develop an account of the normativity of automaticity that responds to and builds upon Tamar Szabó Gendler's account of ‘alief’, an associative and arational mental state more primitive than belief. Alief represents a promising tool for integrating psychological research on automaticity with philosophical work on mind and action, but Gendler errs in (...) overstating the degree to which aliefs are norm-insensitive.

Cognitivists about Practical Rationality argue that we can explain some of the requirements of practical rationality by appealing to the requirements of theoretical rationality. First, they argue that intentions involve beliefs, and, second, they show how the theoretical requirements governing those involved beliefs can explain some of the practical requirements governing those intentions. This paper avoids the ongoing controversy about whether and how intentions involve beliefs and focuses instead on this second part of the Cognitivist approach, where I think Cognitivism (...) faces significant difficulties. I proceed by considering two attempts by Cognitivists to explain requirements of practical rationality and I argue that neither of them succeed. (shrink)

Some philosophers have tried to establish a connection between the normativity of instrumental rationality and the paradox presented by Lewis Carroll in his 1895 paper “What the Tortoise Said to Achilles.” I here examine and argue against accounts of this connection presented by Peter Railton and James Dreier before presenting my own account and discussing its implications for instrumentalism (the view that all there is to practical rationality is instrumental rationality). In my view, the potential for a Carroll-style regress just (...) shows us that since instrumental rationality involves a higher-order commitment to combine our willing an end with our taking the necessary means, it therefore cannot, on pain of regress, itself be added as a conjunct to one of the elements to be combined. This view does not support instrumentalism. (shrink)

This paper addresses the question of whether gathering additional evidence is always rationally required, both from the point of view of instrumental rationality and of epistemic rationality. It is shown that in certain situations, it is not instrumentally rational to look for more evidence before making a decision. These are situations in which the risk of “misleading” evidence – a concept that has both instrumental and epistemic senses – is not offset by the gains from the possibility of non-misleading evidence. (...) These situations also undermine a particular argument for the claim that it is epistemically rational to look for more evidence, though it is argued that the relationship between instrumental and epistemic rationality makes such arguments flawed to begin with. Furthermore, these situations show us that our epistemic and our practical goals sometimes point us in different directions, not merely because of our limited resources or because our desires are sometimes best served by being in particular epistemic states, but because of the nature of rational action.

One consequence of the later Wittgenstein's influential critique of epistemological foundationalism has been to convince many contemporary philosophers that the ideal of universal and necessary cognitive grounds for moral or political norms is illusory. Recent neo-Wittgensteinian accounts of practical reason attempt to formulate a conception of a post-foundational politics in which a political ethos can be legitimate, rational or just even if its informing practices and cognitive standards lack foundational justification. Against these appropriations of Wittgenstein, I argue that his account (...) challenges foundationalism only by generating epistemological relativism at both the first-order level of belief systems and at the second-order level of the comparative evaluation of first-order belief systems and their non-comparable forms of justification. The result is a polytheism of forms of reason which imperils the methodological ideal of a non-relativistic practice of moral-political criticism. (shrink)

This dissertation is about rationality, both practical rationality , and theoretical rationality . I argue that there are interesting similarities as well as interesting differences between practical and theoretical rationality. One of the similarities is that both of them are essentially related to the explanation of actions and beliefs, and one of the differences is that whereas theoretical rationality has the hyper-external aim of truth, practical rationality has the non-hyper-external aim of desire satisfaction. ;In chapter 1 I present a general (...) framework for the development of theories of rationality, and in chapter 2 I apply that framework to practical rationality. The result is an instrumentalist view of practical rationality. In chapter 3 I discuss the relation between practical rationality and morality, and I argue that one can be an instrumentalist about practical rationality without being a subjectivist about morality, even while accepting plausible forms of motivational internalism. In chapter 4 I argue that theoretical rationality is not reducible to practical rationality. In chapter 5 I apply the framework of chapter I to theoretical rationality, and the result is a theory with both internalist and externalist components. In chapters 6 through 8 I defend that theory from some of the main objections that can be leveled at it, such as the objection from disjunctivism and the "new evil demon problem". (shrink)

In “Desire as Belief” and “Desire as Belief II,” David Lewis ( 1988 , 1996 ) considers the anti-Humean position that beliefs about the good require corresponding desires, which is his way of understanding the idea that beliefs about the good are capable of motivating behavior. He translates this anti-Humean claim into decision theoretic terms and demonstrates that it leads to absurdity and contradiction. As Ruth Weintraub ( 2007 ) has shown, Lewis’ argument goes awry at the outset. His decision (...) theoretic formulation of anti-Humeanism is one that no sensible anti-Humean would endorse. My aim is to demonstrate that Lewis’ infelicitous rendering of anti-Humeanism really does undermine the force of his arguments. To accomplish this, I begin by developing a more adequate decision theoretic rendering of the anti-Humean position. After showing that my formulation of anti-Humeanism constitutes a plausible interpretation of the anti-Humean thesis, I go on to demonstrate that if we adopt this more accurate rendition of anti-Humeanism, the view is no longer susceptible to arguments like the ones Lewis has devised. I thereby provide a more robust response to Lewis’ arguments than has yet been offered, and in the process I develop a formulation of anti-Humeanism that creates the possibility for future decision theoretic arguments that, unlike Lewis’, speak directly to the plausibility of anti-Humeanism.

Is practical reason a cognitive faculty? Do practical judgments make claims about a subject matter that are appropriately assessed in terms of their agreement with that subject matter? According to Kantians like Christine Korsgaard, the answer is no. To think otherwise is to conflate the theoretical and the practical, the epistemic and the ethical. I am not convinced. In this paper, I motivate my skepticism through examination of the very figure who inspires Korsgaard’s rejection of cognitivism: Kant. For as I (...) read him, Kant does not construe the distinction between theoretical and practical reason in terms of a distinction between cognitive and non-cognitive faculties but in terms of two distinct applications of a single faculty of reason, which is through-and-through cognitive. Thus, practical, no less than theoretical, reason cognizes a subject matter, and so practical, no less than theoretical, reason is straightforwardly subject to familiar epistemic standards of truth, warrant, and knowledge. Of course, even if I am right about Kant, this does not show that Korsgaard is wrong about reason; and I will offer no direct argument against her position here. Nonetheless, I believe that reflection on Kant’s true view, with its careful treatment of and respect for both the practicality and rationality of reason, should perhaps lead us to rethink what it means to be a rationalist in ethics.

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