This volume represents the most comprehensive and authoritative collection of canonical readings in theory of knowledge. It is ideal as a reader for all courses in epistemology.

Explaining Value is a selection of the best of Gilbert Harman's shorter writings in moral philosophy. The thirteen essays are divided into four sections, which focus in turn on moral relativism, values and valuing, character traits and virtue ethics, and ways of explaining aspects of morality. Harman's distinctive approach to moral philosophy has provoked much interest; this volume offers a fascinating conspectus of his most important work in the area.

Ordinary moral thought often commits what social psychologists call 'the fundamental attribution error '. This is the error of ignoring situational factors and overconfidently assuming that distinctive behaviour or patterns of behaviour are due to an agent's distinctive character traits. In fact, there is no evidence that people have character traits in the relevant sense. Since attribution of character traits leads to much evil, we should try to educate ourselves and others to stop doing it.

In the first chapter, I explain the concept of awareness and the distinction between direct and indirect awareness. Direct awareness of x is understood as awareness of x which is not based on awareness of anything else, and the "based on" relation is understood as a particular way in which one state of awareness can be caused by another state of awareness when the contents of the two states are logically related.

Many epistemologists have been interested in justification because of its presumed close relationship to knowledge. This relationship is intended to be ...

The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (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)

Any satisfactory epistemology must account for the distinction between propositional and doxastic justification. Can infinitism account for it? Proposals to date have been unsatisfactory. This paper advances a new infinitist account of the distinction. The discussion proceeds as follows. Section 1 sets the stage. Section 2 presents Peter Klein's account. Section 3 raises a problem for Klein's account and suggests an improvement. Section 4 raises a further challenge. Sections 5 to 7 consider several unsuccessful attempts to meet the challenge. Section (...) 8 presents my new proposal, which can meet the challenge. Section 9 concludes the discussion. (shrink)

Keith Lehrer is one of the leading proponents of a coherence theory of knowledge that seeks to explain what it means to know in a characteristically human way. Central to his account are the pivotal role played by a principle of self-trust and his insistence that a sound epistemology must ultimately be ecumenical in nature, combining elements of internalism and externalism. The present book is an extensive, self-contained, up-to-date study of Lehrer's epistemological work. Covering all major aspects, it contains original (...) contributions by some of the most distinguished specialists in the field, outgoing from the latest, significantly revised version of Lehrer's theory. All basic ideas are explained in an introductory chapter. Lehrer's extensive replies in a final chapter give unique access to his current epistemological thinking. (shrink)

In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that (...) external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

This collection of papers (including three completely new ones) by one of the foremost philosophers in epistemology transcends two of the most widely misunderstood positions in philosophy--foundationalism and coherentism. Audi proposes a distinctively moderate, internalist foundationalism that incorporates some of the virtues of both coherentism and reliabilism. He develops important distinctions between positive and negative epistemic dependence, substantively and conceptually naturalistic theories, dispositional beliefs and dispositions to believe, episodically and structurally inferential beliefs, first and second order internalism, and rebutting as (...) opposed to refuting skepticism. These contrasts are applied not only to rational belief, but to rational action and the rationality of desires and intentions. The overall position is a pluralist, moderately rationalistic, internalist theory of justification and a partly externalist conception of knowledge. However, by virtue of offering a theory of rationality as well as an account of knowledge and justified belief, it will interest philosophers of ethics, science, and the social sciences and teachers and students of epistemology.

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

The epistemic basing relation is the relation which must hold between a person's belief and the adequate reasons for holding that belief if the belief is to be epistemically justified by those reasons. Although the basing relation is a fundamental component of any adequate theory of epistemic justification, it has received scant attention in the literature. In this paper, I propose a novel causal analysis of the basing relation, one which helps to characterize an intemalist element which, I shall argue, (...) is required of any successful account of epistemic justification, and which confirms current trends away from coherentist and reliabilist theories of justification.

This paper examines the implications of certain social psychological experiments for moral theory—specifically, for virtue theory. Gilbert Harman and John Doris have recently argued that the empirical evidence offered by ‘situationism’ demonstrates that there is no such thing as a character trait. I dispute this conclusion. My discussion focuses on the proper interpretation of the experimental data—the data themselves I grant for the sake of argument. I develop three criticisms of the anti-trait position. Of these, the central criticism concerns three (...) respects in which the experimental situations employed to test someone's character trait are inadequate to the task. First, they do not take account of the subject's own construal of the situation. Second, they include behaviour that is only marginally relevant to the trait in question. Third, they disregard the normative character of the responses in which virtue theory is interested. Given these inadequacies in situationism's operationalized conception of a ‘character trait’, I argue that situationism does not really address the proposition that people have ‘character traits’, properly understood. A fortiori, the social psychological evidence does not refute that proposition. I also adduce some limited experimental evidence in favour of character traits and distil two lessons we can nevertheless learn from situationism. (shrink)

Causation is widely assumed to be a binary relation: c causes e. I will argue that causation is a quaternary, contrastive relation: c rather than C* causes e rather than E*, where C* and E* are nonempty sets of contrast events. Or at least, I will argue that treating causation as contrastive helps resolve some paradoxes.

Actualists routinely characterize their view by means of the slogan, “Everything is actual.” They say that there aren’t any things that exist but do not actually exist—there aren’t any “mere possibilia.” If there are any things that deserve the label ‘possible world’, they are just actually existing entities of some kind—maximally consistent sets of sentences, or maximal uninstantiated properties, or maximal possible states of affairs, or something along those lines. Possibilists, in contrast, do think that there are mere possibilia, that (...) there are things that are not actual. They think that more exists than what actually exists. All I have done so far, though, is rephrase the slogan in various ways. To say that everything is actual is precisely to say that there are no things that do not actually exist, which is precisely to say that there are no mere possibilia, and which is also precisely to say that we cannot sep- arately quantify over what exists and what is actual. These claims all amount to the same thing. But what is that, exactly? What on earth does it mean to say that everything is actual, that there are no mere possibilia, and so on? What does the actualist slogan really come to? I think the literature is far from clear on this point, and that people work themselves into unnecessary muddles because of it. Indeed, certain confusions that I shall discuss in the first half of this article seem to be on the rise. It is high time to lay out the issues and the choice points as clearly as possible. There are two primary choices to be made; there are two axes along which versions of actualism can vary. One choice has to do with how to treat claims about things that merely could exist. The other choice has to do with the modal status of the view and of how we should think about the “actual” in actualism. I make no claim that the positions I will eventually endorse are star- tlingly new. I think that most people will agree with the decisions I make at both choice points and will in fact find some bits of this essay obvious. But not everyone agrees with my decisions, and it has been my experience that people differ remarkably about which bits they find obvious—a fact I find rather telling. My goal, then, is to show that the two axes are there and to clarify the consequences of the choices. (shrink)

The impact moral judgments have on our deliberations and actions seems to vary a great deal. Moral judgments play a large part in the lives of some people, who are apt not only to make them, but also to be guided by them in the sense that they tend to pursue what they judge to be of moral value, and shun what they judge to be of moral disvalue. But it seems unrealistic to claim that moral judgments play a pervasive (...) role in the lives of all or even most people. There are considerable variations in how strong a tendency people have to think in moral terms, and in how such thoughts affect their decisions and actions. For every moral hero who single- mindedly pursues moral values, there are thousands of less com- mitted people who only do so when it does not cost them too much in material comfort, personal relations, or social standing. And of course, what counts as too much varies from person to person. On top of such variations, there are those who consistently display mor- al indifference-people who concede, for example, that certain investment policies have morally problematic consequences, but who can readily and without compunction ignore that in their busi- ness decisions. There even seem to be moral subversives, people who intentionally and knowingly pursue what they acknourledge to be morally u~ong or bad, and do so for that very reason. (shrink)

In this article I set out a reason for believing in a form of metaethical relativism. In rough terms, the reason is this: a widely held thesis, internalism, tells us that to accept (sincerely assert, believe, etc.) a moral judgment logically requires having a motivating reason. Since the connection is logical, or conceptual, it must be explained by a theory of what it is to accept a moral claim. I argue that the internalist feature of moral expressions can best be (...) explained by my version of moral relativism, which I call "speaker relativism.". (shrink)

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence.

A collection of some of Sellars' lectures and articles from 1951 to 1962.

In this concise book, one of the world's leading epistemologists provides a sophisticated, revisionist introduction to the problem of knowledge in Western philosophy. Modern and contemporary accounts of epistemology tend to focus on limited questions of knowledge and skepticism, such as how we can know the external world, other minds, the past through memory, the future through induction, or the world’s depth and structure through inference. This book steps back for a better view of the more general issues posed by (...) the ancient Greek Pyrrhonists. Returning to and illuminating this older, broader epistemological tradition, Ernest Sosa develops an original account of the subject, giving it substance not with Cartesian theology but with science and common sense. -/- Descartes is a part of this ancient tradition, but he goes beyond it by considering not just whether knowledge is possible at all but also how we can properly attain it. In Cartesian epistemology, Sosa finds a virtue-theoretic account, one that he extends beyond the Cartesian context. Once epistemology is viewed in this light, many of its problems can be solved or fall away. -/- The result is an important reevaluation of epistemology that will be essential reading for students and teachers.

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

This book is a provocative contribution to contemporary ethical theory challenging foundational conceptions of character that date back to Aristotle. John Doris draws on behavioral science, especially social psychology, to argue that we misattribute the causes of behavior to personality traits and other fixed aspects of character rather than to the situational context. More often than not it is the situation not the nature of the personality that really counts. The author elaborates the philosophical consequences of this research for a (...) whole array of ethical theories and shows that, once rid of the misleading conception of motivation, moral psychology can support more robust ethical theories and more humane ethical practices.

These thirteen new, specially written essays by a distinguished international line-up of contributors, including some leading contemporary moral philosophers, give a rich and varied view of current work on ethics and practical reason. The three main perspectives on the topic, Kantian, Humean, and Aristotelian, are all well represented. Issues covered include: the connection between reason and motivation; the source of moral reasons and their relation to reasons of self-interest; the relation of practical reason to value, to freedom, to responsibility, and (...) to feelings. The editors' introduction provides a valuable introductory survey of the topic, putting the individual essays in context. Ethics and Practical Reason will be essential reading for scholars, postgraduates, and upper-level undergraduates working in this area. (shrink)

Plantinga examines the nature of epistemic warrant; whatever it is that when added to true belief yields knowledge. This volume surveys current contributions to the debate and paves the way for his owm positive proposal in Warrant and Proper Function.

Several different approaches to the conceptual analysis of causation are guided by the idea that a cause is something that makes a difference to its effects. These approaches seek to elucidate the concept of causation by explicating the concept of a difference-maker in terms of better-understood concepts. There is no better example of such an approach than David Lewis’ analysis of causation, in which he seeks to explain the concept of a difference-maker in counterfactual terms. Lewis introduced his counterfactual theory (...) of causation with these words: 'We think of a cause as something that makes a difference, and the difference it makes must be a difference from what would have happened without it. Had it been absent, its effects—some of them, at least, and usually all—would have been absent as well.' (Lewis 1973b: pp. 160-1) According to Lewis, a cause c makes a difference to an effect e in the sense that if the cause c had not occurred, the effect e would not have occurred either. All we shall see in section 2, Lewis’ theory says there is more to the concept of causation than this counterfactual condition. Lewis is on the right track, I think, in saying that we think of a cause as something that makes a difference and that this thought is best explicated in terms of counterfactual concepts. However, I shall argue that the particular way in which Lewis spells out the concept of a cause as difference-maker is unsatisfactory. For Lewis’ articulation of this concept is distorted by a specific metaphysical assumption: specifically, that causation is an absolute relation, specifiable independently of any contextual factors. The distortion induced by this assumption is reflected in the undiscriminating manner in which his theory generates countless causes for any given effect. However, commonsense judgement is much more discriminating about causes than Lewis’ theory. Accordingly, I claim that Lewis' analysis faces the problem of profligate causes and I outline some specific problem cases in section 3.. (shrink)
