Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

It is often said, metaphorically, that belief "aims" at the truth. This paper proposes a normative interpretation of this metaphor. First, the notion of "epistemic norms" is clarified, and reasons are given for the view that epistemic norms articulate essential features of the beliefs that are subject to them. Then it is argued that all epistemic norms--including those that specify when beliefs count as rational, and when they count as knowledge--are explained by a fundamental norm of correct belief, which requires (...) that, if one considers a proposition at all, one should believe it if and only if it is true.

The agent portrayed in much philosophy of action is, let's face it, a square. He does nothing intentionally unless he regards it or its consequences as desirable. The reason is that he acts intentionally only when he acts out of a desire for some anticipated outcome; and in desiring that outcome, he must regard it as having some value. All of his intentional actions are therefore directed at outcomes regarded sub specie boni: under the guise of the good. This agent (...) is conceived as being capable of intentional action—and hence as being an agent—only by virtue of being a pursuer of value. I want to question whether this conception of agency can be correct. Surely, so general a capacity as agency cannot entail so narrow a cast of mind. Our moral psychology has characterized, not the generic agent, but a particular species of agent, and a particularly bland species of agent, at that. It has characterized the earnest agent while ignoring those agents who are disaffected, refractory, silly, satanic, or punk. I hope for a moral psychology that has room for the whole motley crew. I shall begin by examining why some philosophers have thought that the attitudes motivating intentional actions involve judgments of value. I shall then argue that their conception of these attitudes is incorrect. Finally, I shall argue that practical reason should not be conceived as a faculty for pursuing value. (shrink)

In this book van Fraassen develops an alternative to scientific realism by constructing and evaluating three mutually reinforcing theories.

A version of this paper is forthcoming in Nous.

Why, when asking oneself whether to believe that p, must one immediately recognize that this question is settled by, and only by, answering the question whether p is true? Truth is not an optional end for first-personal doxastic deliberation, providing an instrumental or extrinsic reason that an agent may take or leave at will. Otherwise there would be an inferential step between discovering the truth with respect to p and determining whether to believe that p, involving a bridge premise that (...) it is good (in whichever sense of good one likes, moral, prudential, aesthetic, allthings-considered, etc.) to believe the truth with respect to p. But there is no such gap between the two questions within the first-personal deliberative perspective; the question whether to believe that p seems to collapse into the question whether p is true. (shrink)

Believing that p, assuming that p, and imagining that p involve regarding p as true—or, as we shall call it, accepting p. What distinguishes belief from the other modes of acceptance? We claim that conceiving of an attitude as a belief, rather than an assumption or an instance of imagining, entails conceiving of it as an acceptance that is regulated for truth, while also applying to it the standard of being correct if and only if it is true. We argue (...) that the second half of this claim, according to which the concept of belief includes a standard of correctness, is required to explain the fact that the deliberative question whether to believe that p is transparent to the question whether p. This argument raises various questions. Is there such a thing as deliberating whether to believe? Is the transparency of the deliberative question whether to believe that p the same as the transparency of the factual question whether I do believe that p? We will begin by answering these questions and then turn to a series of possible objections to our argument. (shrink)

This paper describes and defends in detail a novel account of belief, an account inspired by Ryle's dispositional characterization of belief, but emphasizing irreducibly phenomenal and cognitive dispositions as well as behavioral dispositions. Potential externalist and functionalist objections are considered, as well as concerns motivated by the inevitably ceteris paribus nature of the relevant dispositional attributions. It is argued that a dispositional account of belief is particularly well-suited to handle what might be called "in-between" cases of believing - cases in (...) which it is neither quite right to describe a person as having a particular belief nor quite right to describe her as lacking it. (shrink)

The hypothesis that belief aims at the truth has been used to explain three features of belief: (1) the fact that correct beliefs are true beliefs, (2) the fact that rational beliefs are supported by the evidence and (3) the fact that we cannot form beliefs.

In this paper, I explore the question of whether the expected consequences of holding a belief can affect the rationality of doing so. Special attention is given to various ways in which one might attempt to exert some measure of control over what one believes and the normative status of the beliefs that result from the successful execution of such projects. I argue that the lessons which emerge from thinking about the case ofbelief have important implications for the way we (...) should think about the rationality of a number of other propositional attitudes,such as regret, desire, and fear. Finally,I suggest that a lack of clarity with respect to the relevant issues has given rise to a number of rather serious philosophical mistakes. (shrink)

Can we decide to trust? Sometimes, yes. And when we do, we need not believe that our trust will be vindicated. This paper is motivated by the need to incorporate these facts into an account of trust. Trust involves reliance; and in addition it requires the taking of a reactive attitude to that reliance. I explain how the states involved here differ from belief. And I explore the limits of our ability to trust. I then turn to the idea of (...) trusting what others say. I suggest that we sometimes decide to trust people to be sincere and knowledgeable; and that having taken this attitude towards them, we come to believe what they say. I spell out some consequences that this has for an account of testimony, and for van Fraassen's decision theoretic principle of Reflection. (shrink)

I hope to show that, although belief is subject to two quite robust forms of agency, "believing at will" is impossible; one cannot believe in the way one ordinarily acts. Further, the same is true of intention: although intention is subject to two quite robust forms of agency, the features of belief that render believing less than voluntary are present for intention, as well. It turns out, perhaps surprisingly, that you can no more intend at will than believe at will.

In this new book, Foley defends an epistemology that takes seriously the perspectives of individual thinkers. He argues that having rational opinions is a matter of meeting our own internal standards rather than standards that are somehow imposed upon us from the outside. It is a matter of making ourselves invulnerable to intellectual self-criticism. Foley also shows how the theory of rational belief is part of a general theory of rationality. He thus avoids treating the rationality of belief as a (...) fundamentally different kind of phenomenon from the rationality of decision or action. His approach generates promising suggestions about a wide range of issues--e.g., the distinction between epistemic and non-epistemic reasons for belief; the question of what aspects of the Cartesian project are still worth doing; the significance of simplicity and other theoretical virtues; the relevance of skeptical hypotheses; the difference between a theory of rational belief and a theory of knowledge; the difference between a theory of rational belief and a theory of rational degrees of belief; and the limits of idealization in epistemology.

Objects have dispositions. As Nelson Goodman put it, “a thing is full of threats and promises”. But sometimes those threats go unfulfilled, and the promises unkept. Sometimes the dispositions of objects fail to manifest themselves, even when their conditions of manifestation obtain. Pieces of wood, disposed to burn when heated, do not burn when heated in a vacuum chamber. And pastries, disposed to go bad when left lying around too long, won’t do so if coated with lacquer and put on (...) display in a baker ’s window. Any account of what a disposition is, or of what it takes for an object to have a disposition, should be compatible with these commonplace observations. To date, I believe, no adequate account of dispositions has been given, and the aim of this paper is to defend one. (shrink)

It is very common these days to come across the claim that the notions of mental content and linguistic meaning are normative notions. In the work of many philosophers, it plays a pivotal role. Saul Kripke made it the centerpiece of his influential discussion of Wittgenstein’s treatment of rulefollowing and private language; he used it to argue that the notions of meaning and content cannot be understood in naturalistic terms. Kripke’s formulations tend to be in terms of the notion of (...) linguistic meaning, but his argumentative strategy makes it clear that he holds both versions of the claim.... (shrink)

Shared agency is of central importance in our lives in many ways. We enjoy engaging in certain joint activities with others. We also engage in joint activities to achieve complex goals. Current approaches propose that we understand shared agency in terms of the more basic phenomenon of shared intention. However, they have presented two antagonistic views about the nature of this phenomenon. Some have argued that shared intention should be understood as being primarily a structure of attitudes of individual participants (...) and their interrelations (Bratman, Searle, Tuomela and Miller). Others have claimed that shared intention should be regarded as being primarily a normative transaction which gives rise to interpersonal obligations (Gilbert). In contrast to these approaches, I propose a compromise view. I argue that shared intention involves a complex socio-psychological structure which ensures, in the absence of special circumstances, the existence of relevant moral obligations. My argument involves two main steps. First, I show that shared intention includes important relations of mutual reliance between the participants. Then, I argue that the existence of these relations of mutual reliance in shared intention helps us explain why, failing special circumstances, shared intention generates those obligations. This provides, in my view, a solution to the vexed question of the relation between shared intention and interpersonal obligations. (shrink)

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)

This paper criticizes two accounts of the normativity of practical principles: the empiricist account and the rationalist or realist account. It argues against the empiricist view, focusing on the Humean texts that are usually taken to be its locus classicus. It then argues both against the dogmatic rationalist view, and for the Kantian view, through a discussion of Kant's own remarks about instrumental rationality in the second section of the Groundwork. It further argues that the instrumental principle cannot stand alone. (...) Unless there are normative principles directing us to the adoption of certain ends, there can be no requirement to take the means to our ends. The familiar view that the instrumental principle is the only requirement of practical reason is incoherent. (shrink)

This paper addresses some connections between conceptions of the will and the theory of practical reason. The first two sections argue against the idea that volitional commitments should be understood along the lines of endorsement of normative principles. A normative account of volition cannot make sense of akrasia, and it obscures an important difference between belief and intention. Sections three and four draw on the non-normative conception of the will in an account of instrumental rationality. The central problem is to (...) explain the grip of instrumental requirements even in cases in which agents do not fully endorse the ends they are pursuing. The solution I propose appeals to coherence constraints on the beliefs that condition the distinctive volitional stance of intention. (shrink)
