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.

In my 1987 book I tried to understand intentions as, in the basic case, elements of larger and typically partial plans whose primary roles in our lives are ones of coordination and organization, both cross-temporal and social.1 I called this the planning theory of intention. Central to the planning theory is the idea that intentions – in contrast with ordinary desires -- are both embedded in characteristic regularities and are subject to distinctive rational pressures for consistency and coherence. There is, (...) in particular, a rational demand that one’s intentions, taken together with one’s beliefs, fit together into a consistent model of one’s future. There is, further, a rational demand that one’s intentions be means-end coherent in the sense, roughly, that it not be true that one intends E, believes that E requires that one intend means M, and yet not intend M.3 And these norms of consistency and coherence are operative in a planning agent’s practical reasoning.

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.

Cognitivists about Practical Rationality argue that we can explain some of the (apparent) 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 (or they show how these apparently practical requirements are actually theoretical requirements). 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 (apparent) 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)

The standard account of weakness of will identifies it with akrasia, that is, with action against one's best judgment. Elsewhere I have argued that weakness of will is better understood as over-readily giving up on one's resolutions. Many cases of weak willed action will not be akratic: in over-readily abandoning a resolution an agent may well do something that they judge at the time to be best. Indeed, in so far as temptation typically gives rise to judgment shift -- to (...) a tendency to change one's judgment so that one values the tempting option as the best -- weak willed action will typically be akratic. But conversely, strong willed action now looks as though it will be akratic. I argue though that it need not be, once we distinguish between actual judgment, and dispositions to judge. Within this framework, the issue of inverse akrasia looks rather different. I argue that whilst Huckleberry Finn plausibly does show weakness of will in abandoning his resolve to turn Jim in, it is far from clear that he is akratic: a point brought out well in Twain's later additions to the text. Whilst cases of inverse akrasia are clearly theoretically possible, I suggest that, given cognitive dissonance mechanisms, they are unlikely to be very common. (shrink)

In this paper, I explore the relationship between epistemic rationality and instrumental rationality, and I attempt to delineate their respective roles in typical instances of theoretical reasoning. My primary concern is with the instrumentalist conception of epistemic rationality: the view that epistemic rationality is simply a species of instrumental rationality, viz. instrumental rationality in the service of one's cognitive or epistemic goals. After sketching the relevance of the instrumentalist conception to debates over naturalism and 'the ethics of belief', I argue (...) that, despite enjoying considerable popularity among both epistemologists and philosophers of science, it is ultimately indefensible. Having thus argued for the distinctness of epistemic and instrumental rationality, I attempt to clarify the role played by each in typical instances of theoretical reasoning. I suggest that being theoretically rational--that is, being proficient with respect to theoretical reasoning--is best construed as a hybrid virtue, inasmuch as it involves manifesting sensitivity to two very different kinds of reasons.

In his critical works of the 1780's, Kant claims, seemingly inconsistently, that (1) theoretical and practical reason are one and the same reason, applied differently, (2) that he still needs to show that they are, and (3) that theoretical and practical reason are united. I first argue that current interpretations of Kant's doctrine of the unity of reason are insufficient. But rather than concluding that Kant’s doctrine becomes coherent only in the Critique of Judgment, I show that the three statements (...) are compatible, providing a new and more coherent account of Kant's 1780's doctrine of the unity of reason.

According to the Instrumental Conception of Epistemic Rationality believing rationally is believing in such a way so as to best satisfy one’s cognitive goals. I provide a novel argument against the Instrumental Conception on the basis of an unnoticed phenomenon I call “rational preemption.” You can now revise your plans and actions rationally in order to preempt or prevent foreseeable future irrationality. However, you cannot now revise your beliefs rationally in order to preempt or prevent foreseeable future irrationality. The ability (...) to be preemptively practically rational in your actions and plans, but not preemptively epistemically rational in your beliefs, implies that epistemic rationality is not a species of practical rationality, and thus, ICER is false.

What relation is there between knowledge and action? According to Hawthorne and Stanley, where your choice is p-dependent, it is appropriate to treat the proposition that p as a reason for acting iff you know that p (RKP). In this paper, I shall argue that it is permissible to treat something as a reason for action even if it isn't known to be true and address Hawthorne and Stanley's arguments for RKP.

The paper argues that normative reasons are of two fundamental kinds, practical which are value related, and adaptive, which are not related to any value, but indicate how our beliefs and emotions should adjust to fit how things are in the world. The distinction is applied and defended, in part through an additional distinction between standard and non-standard reasons (for actions, intentions, emotions or belief).

Cognitivism about practical reason is the view that intentions involve beliefs, and that the rational requirements on intentions can be explained in terms of the rational requirements on the beliefs that figure in intentions. In particular, cognitivists about practical reason have sought to provide cognitive explanations of two basic requirements of practical rationality: a consistency requirement, according to which it is rationally impermissible to have intentions that are jointly inconsistent with one’s beliefs, and a means-end coherence requirement, according to which, (...) to a first approximation, it is rationally impermissible to intend an end while failing to intend what one regards as a necessary means to this end. In order for the cognitivist to explain these requirements, she must arrive at an account of the beliefs that figure in intentions, on the basis of which she can show that any agent who violates these requirements of pratical rationality must have beliefs that violate the requirements of theoretical rationality. Providing such an account, however, turns out to be no easy task. (shrink)

When we say that a subject has attitudes that she is rationally required to have, does that entail that she has those attitudes for reasons? In other words, is there a deep nexus between being rational and responding to reasons? Many have argued that there is. For example, Derek Parfit tells us that 'to be rational is to respond to reasons' (Parfit 1997, p.99). But I am not so sure. I begin by considering this question in the domain of theoretical (...) rationality. The question in this domain is whether, when a subject has the beliefs that she is required to have by the norms of theoretical rationality, she is responding to reasons that there are for having those beliefs. Armed with a moderately clear answer to this question in the theoretical domain, I consider their relationship in the practical domain. When a subject has the desires that she is required to have by the norms of practical rationality, is she responding to reasons that there are for having those desires? Part of the interest of these questions lies in improving our understanding of reasons for action. I will say a little about this towards the end. (shrink)

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

“What do you see when you look at your face in the mirror?” asks J. David Velleman in introducing his philosophical theory of action. He takes this simple act of self-scrutiny as a model for the reflective reasoning of rational agents: our efforts to understand our existence and conduct are aided by our efforts to make it intelligible. Reflective reasoning, Velleman argues, constitutes practical reasoning. By applying this conception, Practical Reflection develops philosophical accounts of intention, free will, and the foundation (...) of morals. This new edition of Practical Reflection contains the original 1989 text along with a new introduction and is the latest entry in The David Hume Series of Philosophy and Cognitive Science Reissues, which keeps in print previously published indispensable works in the area of cognitive science.

Two of the most prominent questions in Kant's critical philosophy concern reason. The first, central to his theoretical philosophy, is the unprovable pretensions of reason in earlier “rationalist” philosophers, especially Leibniz and Descartes. The second, central to his practical philosophy, is the subservient role accorded to reason by the British empiricists—above all Hume, who declared, “Reason is wholly inactive, and can never be the source of so active a principle as conscience, or a sense of morals.” Treatise, 3.1.1.11; see also (...) the entry on Rationalism vs. Empiricism .) Thus the titles of two key works: the monumental Critique of Pure Reason, and the Critique of Practical Reason that is middle point of his great trio of moral writings (between the Groundwork of the Metaphysics of Morals and The Metaphysics of Morals).
