In this new book, Foley defends an epistemology that takes seriously the perspectives of individual thinkers. He argues that having rational opinions is a matter of meeting our own internal standards rather than standards that are somehow imposed upon us from the outside. It is a matter of making ourselves invulnerable to intellectual self-criticism. Foley also shows how the theory of rational belief is part of a general theory of rationality. He thus avoids treating the rationality of belief as a (...) fundamentally different kind of phenomenon from the rationality of decision or action. His approach generates promising suggestions about a wide range of issues--e.g., the distinction between epistemic and non-epistemic reasons for belief; the question of what aspects of the Cartesian project are still worth doing; the significance of simplicity and other theoretical virtues; the relevance of skeptical hypotheses; the difference between a theory of rational belief and a theory of knowledge; the difference between a theory of rational belief and a theory of rational degrees of belief; and the limits of idealization in epistemology.

To what degree should we rely on our own resources and methods to form opinions about important matters? To what degree should we depend on various authorities, such as a recognized expert or a social tradition? In this provocative account of intellectual trust and authority, Richard Foley argues that it can be reasonable to have intellectual trust in oneself even though it is not possible to provide a defence of the reliability of one's faculties, methods and opinions that does not (...) beg the question. Moreover, he shows how this account of intellectual self-trust can be used to understand the degree to which it is reasonable to rely on alternative authorities. This book will be of interest to advanced students and professionals working in the fields of philosophy and the social sciences as well as anyone looking for a unified account of the issues at the centre of intellectual trust.

What propositions are rational for one to believe? With what confidence is it rational for one to believe these propositions? Answering the first of these questions requires an epistemology of beliefs, answering the second an epistemology of degrees of belief.

Her belief is true, but it isn't knowledge. This is a classic illustration of a central problem in epistemology: determining what knowledge requires in addition to true belief.

An increasing number of epistmeologists claim that having beliefs which are reliable is a prerequisite of having epistemically rational beliefs. Alvin Goldman, for instance, defends a view he calls “historical reliabilism.” According to Goldman, a person S rationally believes a proposition p only if his belief is caused by a reliable cognitive process. Goldman adds that a proposition p is epistemically rational for 5, whether or not it is believed by him, only if there is available to S a reliable (...) cognitive process which if used would result in S’s believing p. Likewise, Marshall Swain, Ernest Sosa, and William Alston all claim that reliability is a prerequisite of epistemic rationality. Swain claims that S rationally believes p only if he has reasons for p which are reliable indicators that p is true. Sosa says S rationally believes p only if the belief is the product of an intellectual virtue, where intellectual virtues are stable dispositions to acquire truths. And, Alston says that S rationally believes p only if the belief is acquired or held in such a way that beliefs held in that way are reliable, i.e., mostly true. (shrink)

In his 1963 article, “Is Justified True Belief Knowledge?”1 Edmund Gettier devised a pair of counterexamples designed to illustrate that knowledge cannot be adequately defined as justified true belief. The basic idea behind both of his counterexamples is that one can be justified in believing a falsehood P from which one deduces a truth Q, in which case one has a justified true belief in Q but does not know Q. Gettier’s article inspired numerous other counterexamples, and the search was (...) on for a fourth condition of knowledge, one that could be added to justification, truth, and belief to produce an adequate analysis of knowledge.

A common complaint against contemporary epistemology is that its issues are too rarified and, hence, of little relevance for the everyday assessments we make of each other=s beliefs. The notion of epistemic rationality focuses on a specific goal, that of now having accurate and comprehensive beliefs, whereas our everyday assessments of beliefs are sensitive to the fact that we have an enormous variety of goals and needs, intellectual as well as nonintellectual. Indeed, our everyday assessments often have a quasi-ethical dimension; (...) we want to know, for example, whether someone has been responsible, or at least non-negligent, in forming opinions. Nevertheless, epistemology, properly conceived, is relevant to our commonplace intellectual concerns. Epistemic rationality is an idealized notion, but its idealized character makes it suitable to serve as a theoretical anchor for other notions of rationality, including notions that are less idealized and, hence, potentially more directly relevant to our everyday assessments.

It is commonly thought that the requirements of inferential justification are such that necessarily the process of inferentially justifying a belief will come to an end. But, If this is so, We should be able to pick out those requirements of justification which necessitate an end to the justification process. Unfortunately, Although there is nearly unanimous agreement as to the need for such an end, It is by no means clear which particular requirements of justification impose this need. I examine (...) and criticize several seemingly plausible ways of showing that regresses of inferential justification are impossible and then propose two requirements of inferential justification which, I argue, Are sufficient to show the impossibility.

This chapter contains section titled: An Unfortunate Assumption Sosa on Knowledge and Justification The Distinctness of Justification and Knowledge.

The central issue of Descartes’s Meditations is an intensely personal one. Descartes asks a simple question of himself, one that each of us can also ask of ourselves, “What am I to believe?” One way of construing this question--indeed, the way Descartes himself construed it--is as a methodological one. The immediate aim is not so much to generate a specific list of propositions for me to believe. Rather, I want to formulate for myself some general advice about how to proceed (...) intellectually.

In “Conceptual Diversity in Epistemology,” Richard Foley reflects on such central topics in epistemology as knowledge, warrant, rationality, and justification, with the purpose of distinguishing such concepts in a general theory. Foley uses “warrant” to refer to that which constitutes knowledge when added to true belief and suggests that rationality and justification are not linked to knowledge by necessity. He proceeds to offer a general schema for rationality. This schema enables a distinction between “rationality” and “rationality all things considered.” Foley (...) proposes how these concepts can work together in a system that “provides the necessary materials for an approach to epistemology that is clarifying, theoretically respectable, and relevant to our actual lives.”.

All of us get opinions from other people. And not just a few. We acquire opinions from others extensively and do so from early childhood through virtually every day of the rest our lives. Sometimes we rely on others for relatively inconsequential information. Is it raining outside? Did the Yankees win today? But we also depend on others for important or even life preserving information. Where is the nearest hospital? Do people drive on the left or the right here? We (...) acquire opinions from family and close acquaintances but also from strangers. We get directions from and heed the warnings of individuals we’ve never met, and likewise read books and articles and listen to television and radio reports authored by individuals we don’t know personally. Moreover, we undertake inquiries in groups in which the group relies on the conclusions of the individuals making up the group. In some of these collective efforts everyone knows one another, for example, a set of neighbors taking a census of birds in the neighborhood. But others, such as the effort to understand gravity, are not so nearly self-contained. Indeed, many of the most impressive human intellectual accomplishments are the collective products of individuals far removed from another in location (and sometimes even over time) who rely on each other’s conclusions without feeling the need to re-confirm them.

The two most fundamental questions for an epistemology are, what is involved in having good reasons to believe a claim, and what is involved in meeting the higher standard of knowing that a claim is true? The theory of justified belief tries to answer the former, whereas the theory of knowledge addresses the latter.

The Geography of Insight argues that the issues of the humanities and sciences are different in kind and that inquiries into these issues also have different characteristics as do the resulting insights. These differences constitute an intellectual geography of the humanities and sciences: a mapping of key features of the two domains.
