In this book Zagzebski gives an extended argument that the self-reflective person is committed to belief on authority. Epistemic authority is compatible with autonomy, but epistemic self-reliance is incoherent. She argues that epistemic and emotional self-trust are rational and inescapable, that consistent self-trust commits us to trust in others, and that among those we are committed to trusting are some whom we ought to treat as epistemic authorities, modeled on the well-known principles of authority of Joseph Raz. These principles apply (...) to authority in the moral and religious domains. (shrink)

In den Elementa juris naturalis behauptet Leibniz, dass es rational ist zu präsumieren, dass eine gegebene Handlung gerecht ist. Diese Behauptung scheint in Widerspruch zu seiner Auffassung zu stehen, dass das, was präsumiert wird, einfacher ist als sein Gegenteil. Nach Leibniz ist einfacher, was weniger Voraussetzungen hat als etwas anderes, wobei er zwischen logischen und ontologischen Voraussetzungen unterscheidet. Dieser Diskussionsbeitrag versucht zu zeigen, dass Voraussetzungen auf der ontologischen Ebene eine oft übersehene Rolle für die Präsumption der Gerechtigkeit einer Handlung spielen (...) und dass sich der scheinbare Widerspruch auf dieser Ebene auflösen lässt. Nach Leibniz ist eine gerechte Handlung eine spezielle Art von Möglichkeit: eine Handlung, die für eine moralische Person möglich ist. Ihm zufolge hat aber ein mögliches Ereignis weniger ontologische Voraussetzungen als ein unmögliches Ereignis, weil die ontologischen Voraussetzungen eines möglichen Ereignisses ein Teil der Voraussetzungen eines unmöglichen Ereignisses sind. Die Präsumption zu Gunsten der Gerechtigkeit einer Handlung lässt sich als Spezialfall der Präsumption zu Gunsten der Möglichkeit eines Ereignisses auffassen. (shrink)

This paper provides an account of what it is to have faith in a proposition p, in both religious and mundane contexts. It is argued that faith in p doesn’t require adopting a degree of belief that isn’t supported by one’s evidence but rather it requires terminating one’s search for further evidence and acting on the supposition that p. It is then shown, by responding to a formal result due to I.J. Good, that doing so can be rational in a (...) number of circumstances. If expected utility theory is the correct account of practical rationality, then having faith can be both epistemically and practically rational if the costs associated with gathering further evidence or postponing the decision are high. If a more permissive framework is adopted, then having faith can be rational even when there are no costs associated with gathering further evidence. (shrink)

In Testimony, Trust, and Authority, Benjamin McMyler argues that philosophers have failed to appreciate the nature and significance of our epistemic dependence ...

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent to believe a proposition is (...) for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny. (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.

Locke usually uses the term “judgment” in a rather narrow but not unusual sense, as referring to the faculty that produces probable opinion or assent.2 His account is explicitly developed in analogy with knowledge, and like knowledge, it is developed in terms of the relation various ideas bear to one another. Whereas knowledge is the perception of the agreement or disagreement of any of our ideas, judgment is the presumption of their agreement or disagreement. Intuitive knowledge is the immediate perception (...) of the agreement or disagreement of two ideas, e.g., white is not black. If we perceive the idea of white, and the idea of black, nothing more is needed to perceive that white and black disagree with respect to identity. We just see or intuit it. Demonstrative knowledge is more complicated. Suppose we have or perceive the idea of the internal angles of a triangle, and also the idea of two right angles. Unless one is a prodigy, we can’t just “see” that these two ideas agree with respect to equality; we require a demonstration. For Locke, such a demonstration requires that we find another idea, such as 180 degrees, so that we can intuit that this idea stands in the relation of equality both to the internal angles of a triangle, and to two right angles. Thus a demonstration, for Locke, is a chain of ideas. (shrink)

We citizens of the 21st century live in a world where division of epistemic labour rules. Most of what we know we learned from the spoken or written word of others, and we depend in endless practical ways on the technological fruits of the dispersed knowledge of others—of which we often know almost nothing—in virtually every moment of our lives. Interest has been growing in recent years amongst philosophers, in the issues in epistemology raised by this fact. One issue concerns (...) the depth and extent of our epistemic dependence on testimony, as we may label this broad epistemic source: Do we have any knowledge at all that is free of epistemic dependence on what we have learned from others? A related question is whether our entitlement to believe what we have learned from others can be explained without invoking any epistemic principles special to testimony. These questions concern, as it were, the macro-epistemology of testimony. In the present discussion I shall focus instead on the micro foundations. Testimony, in our broad sense, can occur through an extensive range of types of spoken and written means of purportedly factual communication, including telephone calls, e-mails and personal letters, lectures and radio broadcasts, newspapers, textbooks and encyclopaedias, personal diaries, and public records of all kinds. But the central paradigm—what started the whole communication thing off—is surely that of face-to-face spoken encounter, when one person tells something to another, thereby intending and hoping to share her knowledge with her audience. I begin by describing the speech act of telling, identifying what takes place in a felicitous act of telling. From the nature of the speech act of telling, we see precisely how it is that knowledge is, when all goes as it should, acquired from teller by trusting hearer, in such an act, and in acts of testimony more broadly.

In this article, I argue that faith’s going beyond the evidence need not compromise faith’s epistemic rationality. First, I explain how some of the recent literature on belief and credence points to a distinction between what I call B-evidence and C-evidence. Then, I apply this distinction to rational faith. I argue that if faith is more sensitive to B-evidence than to C-evidence, faith can go beyond the evidence and still be epistemically rational.

Philosopher, theologian, educational theorist, feminist and political pamphleteer, Mary Astell was an important figure in the history of ideas of the early modern period. Among the first systematic critics of John Locke's entire corpus, she is best known for the famous question which prefaces her Reflections on Marriage: 'If all men are born free, how is it that all women are born slaves?' She is claimed by modern Republican theorists and feminists alike but, as a Royalist High Church Tory, the (...) peculiar constellation of her views sits uneasily with modern commentators. Patricia Springborg's study addresses these apparent paradoxes, recovering the historical and philosophical contexts to her thought. She shows that Astell was not alone in her views; rather, she was part of a cohort of early modern women philosophers who were important for the reception of Descartes and who grappled with the existential problems of a new age.

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning. One of the creators of modern mathematics, and probably the most sophisticated logician between the Middle Ages and Frege, as well as a pioneer of ecumenical theology, he also wrote extensively on such diverse subjects as history, geology, and physics. But the part of his work that is most studied today is probably his writings in metaphysics, which have been (...) the focus of particularly lively philosophical discussion in the last twenty years or so. The writings contain one of the great classic systems of modern philosophy, but the system must be pieced together from a vast and miscellaneous array of manuscripts, letters, articles, and books, in a way that makes especially strenuous demands on scholarship. This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance (the famous theory of monads).

The primary aim of this essay is to explain the central elements of Locke's theory of knowledge. A secondary aim arises from the official definition of knowledge introduced in the opening lines of book IV. Though Locke's repeated statements of the definition are consistent with the initial formulation, the consensus view among commentators is that that official definition is in tension with other book IV doctrines. My broader interpretation involves an effort to render the various doctrines consistent with the official (...) definition. The order of discussion: Section 1 explicates the definition of knowledge. Section 2 explains two main divisions of knowledge – namely, its three degrees, and the four sorts of knowable truths. In Section 3, I consider whether Locke understands knowable truths on a model of analyticity. Section 4 addresses potential problems about the objectivity of knowledge, given Locke's account. Section 5 focuses on external world knowledge – Locke calls this "sensitive knowledge" and it poses special difficulties for the official definition of knowledge. (shrink)

Locke's reputation as a sceptic regarding testimony, and the resultant mockery by epistemologists with social inclinations, is well known. In particular Michael Welbourne, in his article ‘The Community of Knowledge’ (1981), depicts Lockean epistemology as fundamentally opposed to a social conception of knowledge, claiming that he ‘could not even conceive of the possibility of a community of knowledge’. This interpretation of Locke is flawed. Whilst Locke does not grant the honorific ‘knowledge’ to anything short of certainty, he nonetheless held what (...) we would call ‘testimonial knowledge’ in appropriate esteem. This can be shown by his careful distinction between testimony and mere received opinion. Furthermore, this distinction is dependent upon a knowledge community which enables hearers of testimony to access alternative accounts. In view of this, we can consider Locke's Conduct of the Understanding in a new light. Dedicated to the autodidact adult, The Conduct directs the learner to reason clearly and well. One goal is to render adult students capable of assessing testimony. The advice given is social in nature. The student must not limit his study to ‘one sort of men or one sort of books’. Otherwise, he faces the sort of cognitive isolation which would render him a mere receiver of opinion. The picture of Locke that emerges is not that of a dyed-in-the-wool sceptic regarding testimonial knowledge, but of a philosopher who formed an embryonic social epistemology embedded within a programme of adult education.

ABSTRACTThere is good reason to regard John Locke’s treatment of testimony as perhaps the most important of the early modern period. It is sophisticated, well developed, pioneering, and seems to ha...

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.
