This paper describes a theory of accuracy or approximate truth and applies it to problems in the realist interpretation of scientific theories. It argues not only that realism requires approximate truth, but that an adequate theory of approximation also presupposes some elements of a realist interpretation of theories. The paper distinguishes approximate truth from vagueness, probability and verisimilitude, and applies it to problems of confirmation and deduction from inaccurate premises. Basic results are cited, but details appear elsewhere. Objections are surveyed, (...) including arguments by Miller, Laymon, and Laudan. Comparison is made with Niiniluoto's theory of verisimilitude, and the utility of his theory for realism assessed. (shrink)

The major point of contention among the philosophers and mathematicians who have written about the independence results for the continuum hypothesis (CH) and related questions in set theory has been the question of whether these results give reason to doubt that the independent statements have definite truth values. This paper concerns the views of G. Kreisel, who gives arguments based on second order logic that the CH does have a truth value. The view defended here is that although Kreisel's conclusion (...) is correct, his arguments are unsatisfactory. Later sections of the paper advance a different argument that the independence results do not show lack of truth values. (shrink)

The technical results presented here on continuity and approximate implication are obviously incomplete. In particular, a syntactic characterization of approximate implication is highly desirable. Nevertheless, I believe the results above do show that the theory has considerable promise for application to the areas mentioned at the top of the paper.Formulation and defense of realist interpretations of science, for example, require approximate truth because we hardly ever have evidence that a particular scientific theory corresponds perfectly with a portion of the real (...) world. Realists need to assert, then, that evidence for a theory is evidence for its approximate truth, not its truth (see [3] and [18]). Approximate truth is, however, a vague notion, and specification of quantity terms and of a sense of approximation are needed to make precise applications of it. Suitability of both vocabulary and sense of approximation depend on the subject matter, and their selection is a partly empirical matter that raises complex issues. In light of the number of common inferences which are not continuous, realists also need to be concerned about indiscriminate use of deductive logic to derive consequences from approximately true theories. These issues will be considered further in a future paper.Approximate truth also has potential application in areas of artificial intelligence that require inference from inaccurate data. In the ‘qualitative’ physical theories of de Kleer and Brown [6], for example, ‘qualitative’ values are derived by partitioning the real numbers into regions. Inferences leading from inside to outside a region must be identified and avoided, and approximate implication and continuity may prove useful in doing this. More generally, growing use of predicate logic as a programming language invites application of the theory of approximate truth as a symbolic substitute for numerical evaluation of computation errors. This too will be the subject of a future paper. (shrink)

It is a widespread view that Marx did not apply dialectics to nature, and that Engels’s writings on this subject are a distortion of his outlook. This paper examines Marx’s discussion of elliptical motion and some other physical phenomena, and shows that he did indeed find contradictions and oppositions in nature, and thus recognised a dialectics of nature. In addition to analysing relevant passages in Marx’s texts, his study of the physics and mathematics of elliptical motion is reviewed and compared (...) with Hegel’s position. Marx’s conception of how dialectical contradictions are resolved is reviewed in order to interpret his claim that the contradiction in elliptical motion is ‘solved’ but not ‘overcome’ by that motion. Textual evidence is presented that Marx regarded ‘real contradictions’ as resolved only by ‘development’, a process in which the conflict between the opposing sides of the contradiction becomes more intense. The consequences of this interpretation for Marx’s analysis of elliptical motion are explored, and some alternative interpretations are discussed. (shrink)

The concept of "non-antagonistic contradiction" (NAC) was developed in the early 1930s in the Soviet Union to describe the social contradictions of Soviet society. This concept was employed to claim that Soviet social contradictions could be resolved without becoming intense or leading to social upheavals. The numerous attempts by Soviet philosophers to explain the NAC concept resulted in theories that are subject to decisive objections. In particular, the contradictions among the working class, the peasantry, and the intelligentsia of the USSR (...) did not prove to be non-antagonistic according to any of the theories designed to support that characterization. The reasons for the failure of the NAC concept are not confined to the Soviet context, and suggest that the NAC concept represents an important error in dialectical theory. (shrink)

As the subtitle suggests, the book is organized around the themes of judgment, inference and truth. Material for the first two topics is largely taken from the second edition of Bradley's Principles of Logic. The discussion of his conception of truth relies on essays written in reply to various authors. In general, the book is to be welcomed by students of Bradley for its remarkably clear and unpretentious exposition of central themes in these difficult topics.Much of the book is taken (...) up with discussion of the views of Bradley's precursors and contemporaries in British and German idealism, material that is important for understanding Bradley's own views. Hegel scholars may cringe, however, at the oft-repeated claim, stated without qualification, that Hegel regarded thought and reality as identical. Allard argues that Hegel must maintain this because his view of deductive inference required that objects be self-determining, and self-determining objects require the identity of thought and being. The argument is particularly puzzling in the light of the fact that Bradley's view of inference also requires the self-development of its objects, although he denied that thought and reality are identical.

Philosophical orthodoxy holds that Thomas Reid is an externalist concerning epistemic justification, characterizing Reid as holding the key to an externalist response to internalism. These externalist accounts of Reid, however, have neglected his work on prejudice, a heretofore unexamined aspect of his epistemology. Reid’s work on prejudice reveals that he is far from an externalist. Despite the views Reid may have inspired, he exemplifies internalism in opting for an accessibility account of justification. For Reid, there are two normative statuses (...) that a belief might satisfy, being blameless and having a just ground. Through reflection, a rational agent is capable of satisfying both of these statuses, making Reid an accessibility internalist about epistemic justification. (shrink)

Taking a refreshingly hands-on approach to introductory ethics, A 21st Century Ethical Toolbox provides students with a set of tools to help them understand and make a constructive difference in real-life moral controversies. Thoroughly optimistic, it invites students to approach ethical issues with a reconstructive intent, making room for more and better options than the traditional "pro" and "con" positions that have grown up around tough problems like abortion and animal rights. Ideal for introductory and applied ethics courses, this unique (...) text does not treat ethics as a purely academic, historical, or theoretical subject, but as a wide-ranging and ongoing set of challenges that calls for multiple and interwoven kinds of intelligence. It covers the skills that are most vital to making real progress in ethics, including paying careful attention to the values at stake on all sides of an issue; looking for creative opportunities within difficult problems; critical-thinking skills such as defining key terms and making sure to judge similar cases alike; and learning how to engage in constructive dialogue. Instructors can readily use the experiential and applied activities inspired by this "toolbox" of practical skills to design an interactive and collaborative ethics course. Students can carry these essential skills directly from this book into such projects as campaigning for environmental awareness and staffing local homeless shelters. In addition to his own discussion, Weston includes gripping and provocative short selections from essayists, activists, and philosophers, and also cites his own students. Extensive "Exercises and Notes" sections end each chapter, and a detailed appendix offers instructors advice on how to use the Toolbox in the classroom. (shrink)

This collection of germinal work in the field by Anthony Weston presents his pragmatic environmental philosophy, calling for reconstruction and imagination rather than deconstruction and analysis. It is a philosopher's invitation to environmental ethics in an unexpectedly inviting and down-to-earth key. On the pragmatic view advanced here, environmental values are thoroughly natural—what else could they be?—and are open-ended and in flux. Rather than passing judgment on the world as it is, we are called to rediscover and remake the world (...) as it might be. We require an environmental etiquette more than a formal ethic; an etiquette whose development must be an ongoing process; and a process in turn that is genuinely multicentric, challenging us to negotiate our place among the exuberant variety of living and other forms.

This book uses controversies as a gateway through which to explore the origins, ethics, key moments and people in the history of anthropology. It draws on a variety of cases including complicity in 'human zoos', Malinowski's diaries, and the Human Terrain System to explore how anthropological controversies act as a driving force for change, how they offer a window into the history of and research practice in the discipline, and how they might frame wider debates such as those around reflexivity, (...) cultural relativism, and the politics of representation. The volume provokes discussion about research ethics and practice with tangible examples where grey areas are brought into sharp relief. The controversies examined in the book all involve moral or practical ambiguities that offer an opportunity for students to engage with the debate and the dilemmas faced by anthropologists, both in relation to the specific incidents covered and to the problems posed more generally due to the intimate and political implications of ethnographic research.

The method of reflective equilibrium starts with a set of initial judgments about some subject matter and refines that set to arrive at an improved philosophical worldview. However, the method faces two, trenchant objections. The Garbage-In, Garbage-Out Objection argues that reflective equilibrium fails because it has no principled reason to rely on some inputs to the method rather than others and putting garbage-in assures you of getting garbage-out. The Circularity Objection argues that reflective equilibrium fails because it has no principled, (...) non-circular way of sorting whatever is put into the method. The moves required to avoid both objections are instructive. Reflective equilibrium requires a meta-justification, and we offer one that appeals to the epistemic goods that underwrite a view known as phenomenal conservatism. Reflective equilibrium calls on us to start with what seems most likely to be true and to alter that collection of judgments in the ways that seem most likely to get us to the truth. Proceeding in this way is epistemically defensible and unavoidable. Hence, reflective equilibrium is not just good, it’s phenomenal. (shrink)

This volume brings together for the first time a significant number of Reid's manuscript papers on natural history, physiology and materialist metaphysics. An important contribution not only to Reid studies but also to our understanding of eighteenth-century science and its context.

Items were generated to explore the factorial structure of a construct of fundamentalism worded appropriately for Judaism, Christianity, and Islam. Results suggested three underlying dimensions: External versus Internal Authority, Fixed versus Malleable Religion, and Worldly Rejection versus Worldly Affirmation. The three dimensions indicate that religious fundamentalism is a personal orientation that asserts a supra-human locus of moral authority, context unbound truth, and the appreciation of the sacred over the worldly components of experience. The 15-item, 3-dimension solution was evaluated across Mexican (...) and American samples. Fit indexes point out the viability of the new inventory across these two samples henceforward referred to as the Multi-Dimensional Fundamentalism Inventory. Additional validity tests supported that the new inventory was negatively correlated with participants’ integrative complexity in a religious domain–specific way. (shrink)

Teaching philosophy of education offers us a chance to apply the familiar Socratic dialectic to ourselves. But it is very seldom taught in this spirit, if taught at all. Perhaps we fear that such a course would be impossibly self‐referential. This paper argues, however, that precisely this kind of self‐reference could be its strength. I outline a course of this sort, based upon a number of iterations I have taught over the past few years. A range of different classroom styles (...) are enacted and examined for their hidden assumptions about teaching, learning, and knowledge. (shrink)

Thomas Reid was a philosopher who founded the Scottish school of 'common sense'. Much of Reid's work is a critique of his contemporary, David Hume, whose empiricism he rejects. In this work, written after Reid's appointment to a professorship at the university of Glasgow, and published in 1785, he turns his attention to ideas about perception, memory, conception, abstraction, judgement, reasoning and taste. He examines the work of his predecessors and contemporaries, arguing that 'when we find philosophers maintaining that (...) there is no heat in the fire, nor colour in the rainbow … we may be apt to think the whole to be only a dream of fanciful men, who have entangled themselves in cobwebs spun out of their own brain'. Written by one of the Scottish Enlightenment's most important thinkers, this work brings to life the intellectual debates of the time. (shrink)

Given the significant exculpatory power that ignorance has when it comes to moral, legal, and epistemic transgressions, it is important to have an accurate understanding of the concept of ignorance. According to the Standard View of factual ignorance, a person is ignorant that p whenever they do not know that p, while on the New View, a person is ignorant that p whenever they do not truly believe that p. On their own though, neither of these accounts explains how ignorance (...) can often be a degreed notion—how we can sometimes be slightly ignorant, quite ignorant, or completely ignorant that p. In this paper, I will argue that there is a route for advocates of the Standard View and the New View to accommodate the gradability of ignorance. On the view I defend, ‘ignorant’ picks out everyone that is ignorant to some degree, making it possible that ignorance can be both degreed and characterized as a lack of knowledge or true belief. Even though we can be ignorant to a greater or lesser extent, the only way to avoid being ignorant that p is to know or truly believe. (shrink)

Thomas Aquinas produced a voluminous body of work on moral theory, and much of that work is on virtue, particularly the status and value of the virtues as principles of virtuous acts, and the way in which a moral life can be organized around them schematically. Thomas Osborne presents Aquinas's account of virtue in its historical, philosophical and theological contexts, to show the reader what Aquinas himself wished to teach about virtue. His discussion makes the complexities of Aquinas's (...) moral thought accessible to readers despite the differences between Thomas's texts themselves, and the distance between our background assumptions and his. The book will be valuable for scholars and students in ethics, medieval philosophy, and theology. (shrink)

The Supreme Court has maintained that race-neutral admissions policies are preferable to race-conscious approaches, while nevertheless continuing to allow for race-conscious practices. How do we make sense of this? In this article, I use the ideas of ideal and nonideal justice to understand how the Court might maintain that it is not always best to implement the ideal policy.

Who is responsible for growing political polarization? To many, the answer is obvious: Irrational voters are to blame. This irrationality results in motivated, in-group reasoning that only serves to further deepen the political divide. In this piece, I examine a perspective that holds that polarization results, not from irrationality, but from rational responses by voters to their limited epistemic resources.

This essay argues in favor of retaining the positive/normative distinction in economics, in spite of developments in methodology and epistemology that have cast doubt on the possibility of a “value-free” economics. The central claim is that it is worthwhile to distinguish between positive economic analysis and normative judgments, even if economics is viewed as being permeated with ethical values. This argument is presented without trying either to demonstrate that there is a profound epistemological difference between science and ethics or to (...) show that positive science can afford us access to objective reality.
