Social epistemology is a many-splendored subject. Different theorists adopt different approaches and the options are quite diverse, often orthogonal to one another. The approach I favor is to examine social practices in terms of their impact on knowledge acquisition . This has at least two virtues: it displays continuity with traditional epistemology, which historically focuses on knowledge, and it intersects with the concerns of practical life, which are pervasively affected by what people know or don't know. In making this choice, (...) I am not blind to the allure of alternative approaches. In this paper I explain and motivate the knowledge-centered approach by contrasting it with a newly emerging alternative that has a definite appeal of its own. According to this alternative, the chief dimension of social epistemological interest would be rationality rather than knowledge. (shrink)

Introduction i This book is about how we study history, how we research and write about it, and how we read it. In the postmodern age, historians are being ...

The Idea of History is the best-known book of the great Oxford philosopher, historian, and archaeologist R.G. Collingwood. It was originally published posthumously in 1946, having been mainly reconstructed from Collingwood's manuscripts, many of which are now lost. For this revised edition, Collingwood's most important lectures on the philosophy of history are published here for the first time. These texts have been prepared by Jan van der Dussen from manuscripts that have only recently become available. The lectures contain Collingwood's first (...) comprehensive statement of his philosophy of history; they are therefore essential for a full understanding of his thought, and in particular for a correct interpretation of The Idea of History itself. Van der Dussen contributes a substantial introduction in which he explains the background to this new edition and surveys the scholarship of the last fifty years. (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.

This article proposes that a general theory of assessment of historical testimony should do justice to the long tradition of adjudication in accordance with maxims of reliability and competence. I argue that an explanatory genealogical theory (along lines first adumbrated by Charles Seignobos) satisfies this condition, and that it has further notable virtues: respect for the strengths of rival theories, regard for the links between adjudication of testimony and other basic procedures of historical inquiry, and the promise of profitable lines (...) of investigation.

Probabilistic models have much to offer to philosophy. We continually receive information from a variety of sources: from our senses, from witnesses, from scientific instruments. When considering whether we should believe this information, we assess whether the sources are independent, how reliable they are, and how plausible and coherent the information is. Bovens and Hartmann provide a systematic Bayesian account of these features of reasoning. Simple Bayesian Networks allow us to model alternative assumptions about the nature of the information sources. (...) Measurement of the coherence of information is a controversial matter: arguably, the more coherent a set of information is, the more confident we may be that its content is true, other things being equal. The authors offer a new treatment of coherence which respects this claim and shows its relevance to scientific theory choice. Bovens and Hartmann apply this methodology to a wide range of much discussed issues regarding evidence, testimony, scientific theories, and voting. Bayesian Epistemology is an essential tool for anyone working on probabilistic methods in philosophy, and has broad implications for many other disciplines. (shrink)

The fact that much of our knowledge is gained through the testimony of others challenges a certain form of epistemic individualism. We are clearly not autonomous knowers. But the discussion surrounding testimony has maintained a commitment to what I have elsewhere called epistemic agent individualism. Both the reductionist and the anti-reductionist have focused their attention on the testimony of individuals. But groups, too, are sources of testimony - or so I shall argue. If groups can be testifiers, a natural question (...) to ask is whether our beliefs based on the testimony of groups are ever justified and whether such a justification is to be conferred inferentially or non-inferentially. I consider and dismiss the possibility of extending an anti-reductionist account of justification to our group testimonial beliefs. I also argue against a version of reductionism that would have our group testimonial beliefs justified only in so far as we were able to monitor the trustworthiness of members of the group. However, there are forms of reductionism that can be extended to make sense of the justification of our group testimonial beliefs. There are mechanisms for monitoring the trustworthiness and competency of a group (rather than its members) and, further, a variety of background beliefs allow us to assess the testimony of a group for reliability.

This paper develops a descriptive and normative account of how people respond to testimony. It postulates a default pathway in which people more or less automatically respond to a claim by accepting it, as long as the claim made is consistent with their beliefs and the source is credible. Otherwise, people enter a reflective pathway in which they evaluate the claim based on its explanatory coherence with everything else they believe. Computer simulations show how explanatory coherence can be maximized in (...) real-life cases, taking into account all the relevant evidence including the credibility of whoever is making a claim. The explanatory-coherence account is more plausible both descriptively and normatively than a Bayesian account. (shrink)

Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication, published originally as a paper on communication theory more than fifty years ago. Republished in book form shortly thereafter, it has since gone through four hardcover and sixteen paperback printings. It is a revolutionary work, astounding in its foresight and contemporaneity. The University of Illinois Press is pleased and honored (...) to issue this commemorative reprinting of a classic. (shrink)

How can we know what really happened in the distant past in places like ancient Egypt, Mesopotamia, Palestine, Greece, and Rome, especially since the evidence is fragmentary and ancient cultures are so different from our own frame of reference? Scholars may examine historical documents and archaeological artifacts, and then make reasonable inferences. But in the final analysis there can be no absolute certainty about events far removed from present reality, and the past must be reconstructed by means of hypotheses that (...) coherently organize all available data. Knowledge claims about the past, and about many areas of science as well, rest on a network of interdependence between theory and evidence, and between interpretation and data. In this fascinating study of epistemology, philosopher Peter Kosso argues for a coherence model of epistemic justification. In the first part, the conceptual argument, he proposes a model of knowledge of the past. In the second part he presents three detailed case studies drawn from the work of historians and archaeologists. These studies are used to support and fine-tune the model outlined in the first part. Kosso presents many insights into the limits of knowledge and our ability to know the mental as well as the physical past. Historians, archaeologists, philosophers, and students interested in epistemology will find this accessible work to be of great value. (shrink)

Mainstream and Formal Epistemology provides the first, easily accessible, yet erudite and original analysis of the meeting point between mainstream and formal theories of knowledge. These two strands of thinking have traditionally proceeded in isolation from one another, but in this book, Vincent F. Hendricks brings them together for a systematic comparative treatment. He demonstrates how mainstream and formal epistemology may significantly benefit from one another, paving the way for a new unifying program of 'plethoric' epistemology. His book will both (...) define and further the debate between philosophers from two very different sides of the epistemological spectrum. (shrink)

We know that we can learn much from the reports of multiple competent, independent, unbiased observers. There are also things we can learn from the reports of competent but biased observers. Specifically, when reports go against the grain of an agent’s known biases, we can be relatively confident in the veracity of those reports. Triangulating on the truth via that mechanism requires a multiplicity of observers with distinct biases, each of whose reports might be one-way decisive in that fashion. It (...) also presupposes that all observers share the same fundamental epistemic standards. (shrink)

How should we evaluate an argument in which two witnesses independently testify to some claim? In fact what would happen is that the testimony of the second witness would be taken to corroborate that of the first to some extent, thereby boosting up the plausibility of the first argument from testimony. But does that commit the fallacy of double counting, because the second testimony is already taken as independent evidence supporting the claim? Perhaps the corroboration effect should be considered illogical, (...) since each premise should be seen as representing a separate reason in a convergent argument for accepting the claim as plausible. In this paper, we tackle the problem using argumentation schemes and argument diagramming. We examine a number of examples, and come up with two hypotheses that offer methods of analyzing and evaluating this kind of evidence. (shrink)

This paper aims to reconcile (i) the intuitively plausible view that a higher degree of coherence among independent pieces of evidence makes the hypothesis they support more probable, and (ii) the negative results in Bayesian epistemology to the effect that there is no probabilistic measure of coherence such that a higher degree of coherence among independent pieces of evidence makes the hypothesis they support more probable. I consider a simple model in which the negative result appears in a stark form: (...) the prior probability of the hypothesis and the individual vertical relations between each piece of evidence and the hypothesis completely determine the conditional probability of the hypothesis given the total evidence, leaving no room for the lateral relation (such as coherence) among the pieces of evidence to play any role. Despite this negative result, the model also reveals that a higher degree of coherence is indirectly associated with a higher conditional probability of the hypothesis because a higher degree of coherence indicates stronger individual supports. This analysis explains why coherence appears truth-conducive but in such a way that it defeats the idea of coherentism since the lateral relation (such as coherence) plays no independent role in the confirmation of the hypothesis.
