The paper argues for the centrality of believing the speaker (as distinct from believing the statement) in the epistemology of testimony, and develops a line of thought from Angus Ross which claims that in telling someone something, the kind of reason for belief that a speaker presents is of an essentially different kind from ordinary evidence. Investigating the nature of the audience's dependence on the speaker's free assurance leads to a discussion of Grice's formulation of non-natural meaning in an epistemological (...) light, concentrating on just how the recognition of the speaker's self-reflexive intention is supposed to count for his audience as a reason to believe P. This is understood as the speaker's explicitly assuming responsibility for the truth of his statement, and thereby constituting his utterance as a reason to believe. (shrink)

The fundamental question of the ethics of belief is "What ought one to believe?" According to the traditional view of evidentialism, the strength of one's beliefs should be proportionate to the evidence. Conventional ways of defending and challenging evidentialism rely on the idea that what one ought to believe is a matter of what it is rational, prudent, ethical, or personally fulfilling to believe. Common to all these approaches is that they look outside of belief itself to determine what one (...) ought to believe. In this book Jonathan Adler offers a strengthened version of evidentialism, arguing that the ethics of belief should be rooted in the concept of belief—that evidentialism is belief's own ethics. A key observation is that it is not merely that one ought not, but that one cannot, believe, for example, that the number of stars is even. The "cannot" represents a conceptual barrier, not just an inability. Therefore belief in defiance of one's evidence (or evidentialism) is impossible. Adler addresses such questions as irrational beliefs, reasonableness, control over beliefs, and whether justifying beliefs requires a foundation. Although he treats the ethics of belief as a central topic in epistemology, his ideas also bear on rationality, argument and pragmatics, philosophy of religion, ethics, and social cognitive psychology.

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 a focused assessment of one of the founding members of the liberal tradition in philosophy and a self-proclaimed “Under-Labourer” working to support the scientific revolution of the seventeenth century, the author maps the full range of John Locke’s highly influential ideas, which even today remain at the heart of debates about the nature of reality and our knowledge of it, as well as our moral and political rights and duties. Comprehensive introduction to the full range of Locke’s ideas, providing (...) an up-to-date account that acknowledges issues raised by recent scholarship over the past decade A well-rounded perspective on one of the intellectual giants of the western philosophical tradition Provides detailed coverage of Locke’s two key works, _An Essay Concerning Human Understanding_ and _The Two Treatises of Government_. A sophisticated analysis by a highly respected academic A vital addition to the _Blackwell_ _Great Minds_ series. (shrink)

In “The Sources of Knowledge,” Robert Audi distinguishes what he calls the “four standard basic sources” by which we acquire knowledge or justified belief: perception, memory, consciousness, and reason. With the exception of memory, he distinguishes each of the above as a basic source of knowledge. Audi contrasts basic sources with nonbasic sources, concentrating on testimony. After clarifying the relationship between a source and a ground, or “what it is in virtue of which one knows or justifiedly believes,” Audi evaluates (...) the basic sources’ individual and collective autonomy as well as their vulnerability to defeasibility. He also examines the relationship of coherence to knowledge and justification, noting the distinction between a negative dependence on incoherence and a positive dependence on coherence. (shrink)

Since its publication in the mid-eighteenth century, Hume's discussion of miracles has been the target of severe and often ill-tempered attacks. In this book, one of our leading historians of philosophy offers a systematic response to these attacks. Arguing that these criticisms have--from the very start--rested on misreadings, Robert Fogelin begins by providing a narrative of the way Hume's argument actually unfolds. What Hume's critics have failed to see is that Hume's primary argument depends on fixing the appropriate standards of (...) evaluating testimony presented on behalf of a miracle. Given the definition of a miracle, Hume quite reasonably argues that the standards for evaluating such testimony must be extremely high. Hume then argues that, as a matter of fact, no testimony on behalf of a religious miracle has even come close to meeting the appropriate standards for acceptance. Fogelin illustrates that Hume's critics have consistently misunderstood the structure of this argument--and have saddled Hume with perfectly awful arguments not found in the text. He responds first to some early critics of Hume's argument and then to two recent critics, David Johnson and John Earman. Fogelin's goal, however, is not to "bash the bashers," but rather to show that Hume's treatment of miracles has a coherence, depth, and power that makes it still the best work on the subject.

Locke Defines Knowledge at the beginning of Book IV of the Essay concerning Human Understanding as “the perception of the connexion and agreement, or disagreement and repugnancy of any of our Ideas” (E IV.i.2).1 So defined, knowledge varies along two dimensions. On the one hand, there are four “sorts” of knowledge: of identity or diversity; relation; co-existence or necessary connection; and real existence. On the other hand, there are three “degrees” of knowledge: intuitive knowledge, which consists in the “immediate” perception (...) of agreement or disagreement between ideas (E IV.ii.1); demonstrative knowledge, which consists in the perception of agreement or disagreement by way of intermediate (or intervening) ..

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.

Many critics of Locke have worried that restricting knowledge to relationships among ideas would bar knowledge from extending to the outer reality which "corresponds to" these ideas. The question of how well Locke can answer such concerns leads us into a number of peculiar and intriguing passages on knowledge and the relationships between perception, reality, pain, and pleasure. This chapter examines what John Locke has to say about sensitive knowledge, to investigate several ways in which his remarks on this topic (...) can be reconciled with what he says elsewhere. It also talks about the idea of sensation, and assesses the merits of Locke's conception of sensitive knowledge both as a response to skepticism and as a part of the larger picture of human understanding painted in the Essay. Two passages in the Essay describe sensitive knowledge in some detail, both beginning with a description of the skeptical problem. (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.
