Christine Korsgaard has become one of the leading interpreters of Kant's moral philosophy. She is identified with a small group of philosophers who are intent on producing a version of Kant's moral philosophy that is at once sensitive to its historical roots while revealing its particular relevance to contemporary problems. She rejects the traditional picture of Kant's ethics as a cold vision of the moral life which emphasises duty at the expense of love and value. Rather, Kant's work is seen (...) as providing a resource for addressing not only the metaphysics of morals, but also for tackling practical questions about personal relations, politics, and everyday human interaction. This collection contains some of the finest current work on Kant's ethics and will command the attention of all those involved in teaching and studying moral theory. (shrink)

It is argued that reliance on the testimony of others cannot be viewed as reliance on a kind of evidence. Speech being essentially voluntary, the speaker cannot see his own choice of words as evidence of their truth, and so cannot honestly offer them to others as such. Rather, in taking responsibility for the truth of what he says, the speaker offers a guarantee or assurance of its truth, and in believing him the hearer accepts this assurance. I argue that, (...) contrary to appearances, this account is compatible with the hearer acquiring knowledge, and in fact throws interesting light on the idea of knowledge. -/- . (shrink)

Our trust in the word of others is often dismissed as unworthy, because the illusory ideal of "autonomous knowledge" has prevailed in the debate about the nature of knowledge. Yet we are profoundly dependent on others for a vast amount of what any of us claim to know. Coady explores the nature of testimony in order to show how it might be justified as a source of knowledge, and uses the insights that he has developed to challenge certain widespread assumptions (...) in the areas of history, law, mathematics, and psychology.

Immanuel Kant is often regarded as an exponent of the ‘individualist’ tradition in epistemology, according to which testimony is not a fundamental source of knowledge. The present paper argues that this view is far from accurate. Kant devotes ample space to discussions of testimony and, in his lectures on logic, arrives at a distinct and stable philosophical position regarding testimony. Important elements of this position consist in (a) acknowledging the ineliminability of testimony; (b) realizing that testimony can establish empirical knowledge (...) with certainty; (c) establishing a presumptive principle regarding the acceptance of testimony; (d) arguing for a symmetry between knowledge based on experience and knowledge based on testimony. Rejecting testimony as a fundamental source of knowledge merely on the basis that no theoretically necessary ground for its truth can be given, would, as Kant puts it, indicate ‘a lack of moral interest’. Such ‘incredulity’ would be a form of ‘logical egoism’: it demonstrates an unwillingness or inability to think oneself in the place of others, yet this we must do if we are to trust our own judgements. While Kant strongly endorses testimony as a source of empirical knowledge, he does, however, make one important restriction: ‘Propositions of reason’ (Vernunftwahrheiten), such as universal moral principles, may not be adopted on the basis of testimony. I argue that this distinction, between testimonial knowledge of empirical matters of fact and individual knowledge of propositions of reason, is an important element of Kant’s epistemology of testimony, as it explains how his strong endorsement of testimony as a source of knowledge can be squared with his equally strong demand for intellectual autonomy. Finally, I comment on the overall implications of this account for Kant’s discussion, elsewhere in his work, of the public nature of communication. (shrink)

Thomas Reid, the Scottish natural and moral philosopher, was one of the founding members of the Aberdeen Philosophical Society and a significant figure in the Scottish Enlightenment. Reid believed that common sense should form the foundation of all philosophical inquiry. He criticised the sceptical philosophy propagated by his fellow Scot David Hume and the Anglo-Irish bishop George Berkeley, who asserted that the external world did not exist outside the human mind. Reid was also critical of the theory of ideas propagated (...) by Locke and Descartes, arguing that it was incompatible with physical and experiential facts. For Reid, our senses demonstrate that the external world must exist, and this work is organised in chapters examining each of the senses in turn. The book, based on his lectures, was first published in 1764 when Reid was a regent professor at King's College, Aberdeen, and was reissued in 1818. (shrink)

Theories of epistemically justified belief have long assumed individualism. In its extreme, or Lockean, form individualism rules out justified belief on testimony by insisting that a subject is justified in believing a proposition only if he or she possesses first-hand justification for it. The skeptical consequences of extreme individualism have led many to adopt a milder version, attributable to Hume, on which a subject is justified in believing a proposition only if he or she is justified in believing that there (...) is testimony in favor of the proposition deriving from a reliable source. I argue that this Humean individualism also leads to skepticism in a wide range of cases; it makes it impossible for a layperson to be justified on expert testimony. In addition, I argue that the apparent motivation for the Humean view, an insistence on intellectual autonomy in justification, does not succeed in motivating it. I then explore the contours of a collectivist view of justification on testimony, with special attention to the place of a subject's intellectual autonomy in such justification. I try to bring empirical results of the psychology of persuasion to bear on the epistemological issues. (shrink)

This book follows hard upon Korsgaard's The Sources of Normativity. Both present the author's influential version of a Kantian theory of normative ethics and metaethics. Whereas The Sources of Normativity was a systematic investigation of "normativity" written as a single unit, the present volume is a collection of previously published papers, some of them already well known and much discussed, dating between 1983 and 1993. By the nature of the case, one might expect less thematic unity in this book than (...) in the other one, but the present book is a deeper and more wide ranging presentation of the author's views. Korsgaard's historical focus in The Sources of Normativity is less on Kant and more on the British moralists. Creating the Kingdom of Ends deals quite explicitly with the interpretation of Kant's moral philosophy. The papers in this book contain, in my judgment, the heart of Korsgaard's work: a variety of fresh and illuminating insights into Kant's moral theory and its relation to contemporary ethical theory which have helped to reshape the image of Kant's ethics and to refocus the issues dealt with in current moral philosophy. Or to make claims less grand but of more immediate relevance to this review, there is no question that some of the papers in this book have helped to reshape both the present writer's image of Kant's ethics and his conception of the way questions of ethical theory should be addressed. I hope below to say something both about where I think Korsgaard has gotten these matters right, and where I find her position either unclear or dubious. (shrink)

In a recent paper titled “Content Preservation”, Tyler Burge argues that certain psychological processes play a purely preservative role, and not a justificatory role. Burge’s claim is that the justificatory force of the beliefs sustained by these processes is independent of features of these processes, such as their reliability. The function of these psychological processes is merely to preserve the beliefs in order to “assure the proper working of other cognitive capacities over time”. In particular, Burge claims that the memory (...) processes underlying deductive reasoning and the psychological processes underlying verbal communication are purely preservative. (shrink)

Through communication, we form beliefs about the world, its history, others and ourselves. A vast proportion of these beliefs we count as knowledge. We seem to possess this knowledge only because it has been communicated. If those justifications that depended on communication were outlawed, all that would remain would be body of illsupported prejudice. The recognition of our ineradicable dependence on testimony for much of what we take ourselves to know has suggested to many that an epistemological account of testimony (...) should be essentially similar to accounts of perception and memory. This premise I want to dispute. (shrink)

In this paper I focus on John Locke as a representative figure of English Enlightenment theorizing about the legitimacy of cognitive authority and examine the way in which a greater attention to the cultural milieu in which Locke worked can lead to a profound reexamination of his writings on cognitive authority. In particular, I suggest that an inattention to the rise of a culture of reading and the growing availability of books in Early Modern England has led historians of philosophy (...) largely to misrepresent Locke's theory of testimonial justification. At the core of my paper are two interrelated claims. First, with respect to the history of ideas, I argue that the Locke's interest in testimony as a source of justification was in fact greater than that of his Scholastic forebears, and that this fact has a simple, if as yet unacknowledged, cultural cause -- viz., the rise of the book as a mass commodity in the late 17th century. Second, with respect to the history of philosophy more particularly, I argue that this failure to acknowledge the cultural movements that led to a consideration of testimony as a topic of interest to epistemologists in the Modern era has led to a misreading of Locke's work on the subject. Indeed, Locke, though usually read as having attempted to denigrate testimony as a legitimate source of justification, in fact sought to devise an epistemology that would do justice to the centrality of testimony in the intellectual lives of growing numbers of his contemporaries in 17th and 18th century England and Scotland.
