In this paper several problems are raised concerning Ian Barbour's four ways of interrelating science and religion—Conflict, Independence, Dialogue, and Integration—as put forward in such publications as his highly influential Religion in an Age of Science (1990) and widely adopted by other writers in this field. The authors argue that this taxonomy is not very useful or analytically helpful, especially to historians seeking to understand past engagements between science and religion.

This popular selection of Wittgenstein’s key writings has now been updated to include new material relevant to recent debates about the philosopher. Follows the evolution of Wittgenstein’s philosophical thought from the Tractatus Logico-Philosophicus through to the Philosophical Investigations. Excerpts are arranged by topic and introduce readers to all the central concerns of Wittgenstein’s philosophy. Now includes a new chapter on ‘Sense, Nonsense and Philosophy’ incorporating material relevant to recent debates about Wittgenstein.

First published in 1973, Sir Anthony Kenny’s classic introduction to Wittgenstein was widely praised for offering a lucid and historically informed account of the philosopher’s core concerns. Kenny's study is also remarkable for demonstrating the continuity between Wittgenstein’s early and late writings. Focusing on Wittgenstein’s philosophy of mind and language, Kenny closely examines the works of the middle years. He exposes apparent conflicts and then goes on to reconcile them, providing a persuasive argument for the unity of (...) Wittgenstein’s thought. This revised edition includes an extensive new introduction in which Kenny outlines developments in Wittgenstein scholarship since the book was first published and assesses Wittgenstein’s influence in the latter part of the twentieth century.

We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

Many philosophers have argued that "degree of belief" or "credence" is a more fundamental state grounding belief. Many other philosophers have been skeptical about the notion of "degree of belief", and take belief to be the only meaningful notion in the vicinity. This paper shows that one can take belief to be fundamental, and ground a notion of "degree of belief" in the patterns of belief, assuming that an agent has a collection of beliefs that isn't dominated by some other (...) collection in terms of the overall balance of truth and falsity that it could contain.

Many philosophers have become worried about the use of standard real numbers for the probability function that represents an agent's credences. They point out that real numbers can't capture the distinction between certain extremely unlikely events and genuinely impossible ones—they are both represented by credence 0, which violates a principle known as “regularity.” Following Skyrms 1980 and Lewis 1980, they recommend that we should instead use a much richer set of numbers, called the “hyperreals.” This essay argues that this popular (...) view is the result of two mistakes. The first mistake, which this essay calls the “numerical fallacy,” is to assume that a distinction that isn't represented by different numbers isn't represented at all in a mathematical representation. In this case, the essay claims that although the real numbers do not make all relevant distinctions, the full mathematical structure of a probability function does. The second mistake is that the hyperreals make too many distinctions. They have a much more complex structure than credences in ordinary propositions can have, so they make distinctions that don't exist among credences. While they might be useful for generating certain mathematical models, they will not appear in a faithful mathematical representation of credences of ordinary propositions. (shrink)

It is sometimes alleged that arguments that probability functions should be countably additive show too much, and that they motivate uncountable additivity as well. I show this is false by giving two naturally motivated arguments for countable additivity that do not motivate uncountable additivity.

Expected accuracy arguments have been used by several authors (Leitgeb and Pettigrew, and Greaves and Wallace) to support the diachronic principle of conditionalization, in updates where there are only finitely many possible propositions to learn. I show that these arguments can be extended to infinite cases, giving an argument not just for conditionalization but also for principles known as ‘conglomerability’ and ‘reflection’. This shows that the expected accuracy approach is stronger than has been realized. I also argue that we should (...) be careful to distinguish diachronic update principles from related synchronic principles for conditional probability. (shrink)

Cross-situational learning is a mechanism for learning the meaning of words across multiple exposures, despite exposure-by-exposure uncertainty as to the word's true meaning. We present experimental evidence showing that humans learn words effectively using cross-situational learning, even at high levels of referential uncertainty. Both overall success rates and the time taken to learn words are affected by the degree of referential uncertainty, with greater referential uncertainty leading to less reliable, slower learning. Words are also learned less successfully and more slowly (...) if they are presented interleaved with occurrences of other words, although this effect is relatively weak. We present additional analyses of participants’ trial-by-trial behavior showing that participants make use of various cross-situational learning strategies, depending on the difficulty of the word-learning task. When referential uncertainty is low, participants generally apply a rigorous eliminative approach to cross-situational learning. When referential uncertainty is high, or exposures to different words are interleaved, participants apply a frequentist approximation to this eliminative approach. We further suggest that these two ways of exploiting cross-situational information reside on a continuum of learning strategies, underpinned by a single simple associative learning mechanism.

I defend a causal reductionist account of the nature of rates of change like velocity and acceleration. This account identifies velocity with the past derivative of position and acceleration with the future derivative of velocity. Unlike most reductionist accounts, it can preserve the role of velocity as a cause of future positions and acceleration as the effect of current forces. I show that this is possible only if all the fundamental laws are expressed by differential equations of the same order. (...) Consideration of the continuity of time explains why the differential equations are all second order. This explanation is not available on non-causal or non-reductionist accounts of rates of change. Finally, I argue that alleged counterexamples to the reductionist account involving physically impossible worlds are irrelevant to an analysis of the properties that play a causal role in the actual world. 1 Background2 Grounding3 Causation4 The Proposal5 Why No Third Derivatives?6 Why Any Derivatives?7 Counterexamples?

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly designed, (...) or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

Bayesianism is a collection of positions in several related fields, centered on the interpretation of probability as something like degree of belief, as contrasted with relative frequency, or objective chance. However, Bayesianism is far from a unified movement. Bayesians are divided about the nature of the probability functions they discuss; about the normative force of this probability function for ordinary and scientific reasoning and decision making; and about what relation (if any) holds between Bayesian and non-Bayesian concepts.

To the extent that we have reasons to avoid these “bad B -properties”, these arguments provide reasons not to have an incoherent credence function b — and perhaps even reasons to have a coherent one. But, note that these two traditional arguments for probabilism involve what might be called “pragmatic” reasons (not) to be (in)coherent. In the case of the Dutch Book argument, the “bad” property is pragmatically bad (to the extent that one values money). But, it is not clear (...) whether the DBA pinpoints any epistemic defect of incoherent agents. The same can be said for Representation Theorem arguments, since they involve the structure of an agent’s preferences. (shrink)

Naive versions of decision theory take probabilities and utilities as primitive and use expected value to give norms on rational decision. However, standard decision theory takes rational preference as primitive and uses it to construct probability and utility. This paper shows how to justify a version of the naive theory, by taking dominance as the most basic normatively required preference relation, and then extending it by various conditions under which agents should be indifferent between acts. The resulting theory can make (...) all the decisions of classical expected utility theory, plus more in cases where expected utilities are infinite or undefined. Although the theory requires similarly strong assumptions to classical expected utility theory, versions of the theory can be developed with slightly weaker assumptions, without having to prove a new representation theorem for the weaker theory. This alternate foundation is particularly useful if probability is prior to preference, as suggested by the recent program to base probabilism on accuracy and alethic considerations rather than pragmatic ones.

Temkin's book is a very original and deeply unsettling work of skeptical philosophy that mounts an important new challenge to contemporary ethics.

In the first paper, I discussed the basic claims of Bayesianism (that degrees of belief are important, that they obey the axioms of probability theory, and that they are rationally updated by either standard or Jeffrey conditionalization) and the arguments that are often used to support them. In this paper, I will discuss some applications these ideas have had in confirmation theory, epistemol- ogy, and statistics, and criticisms of these applications.

Mental or computer simulation of cause and effect of certain behaviors is a recognized approach to changing one’s attitude or triggering an action. Meanwhile, psychology research results suggest that frequency of simulation may affect the corresponding persuasiveness. This paper argues that with always-on sensing and data-driven visualization technologies, interactive tangible systems can be designed to simulate hypothetical outcomes of real-life behaviors in everyday contexts, which repeatedly stimulate users’ imagination of behavioral consequences and thereby behavioral intentions. To investigate the effect, a (...) working prototype of Incingarette, including a smart ashtray in connection with a digital picture frame, was built. When the ashtray is used for smoking, the digital picture is incrementally covered by virtual dust. Field trials involved participants in five daily smoking sessions. Post-session surveys show increasingly stronger perceived causality between smoking and the simulated outcomes, increasingly more vivid mental imagery of consequences, and increasingly intense intention to reduce smoking. Results suggest that repeatedly presenting simulated outcomes cognitively linked to real-life behaviors can increase behavioral intentions. (shrink)

Smith gives an excellent overview on research in language evolution, in which he discusses several recent models of how linguistic systems and the cognitive capacities involved in language learning may have co‐evolved. He illustrates how combined pressures on language learning and communication/use produce compositionally structured languages. Once in place, a (culturally transmitted) communication system creates new selection pressures on the capacity for acquiring these systems.

In a series of papers, Don Fallis points out that although mathematicians are generally unwilling to accept merely probabilistic proofs, they do accept proofs that are incomplete, long and complicated, or partly carried out by computers. He argues that there are no epistemic grounds on which probabilistic proofs can be rejected while these other proofs are accepted. I defend the practice by presenting a property I call ‘transferability’, which probabilistic proofs lack and acceptable proofs have. I also consider what this (...) says about the similarities between mathematics and, on the one hand natural sciences, and on the other hand philosophy. (shrink)

Laudan constructs a fresh approach to a longtime problem for the philosopher of science: how to explain the simultaneous and widespread presence of both agreement and disagreement in science. Laudan critiques the logical empiricists and the post-positivists as he stresses the need for centrality and values and the interdependence of values, methods, and facts as prerequisites to solving the problems of consensus and dissent in science.

I consider the notions of logical probability, degree of belief, and objective chance, and argue that a different formalism for conditional probability is appropriate for each.

This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly 'naturalistic' forms of scientific (...) realism.

Fine has shown that assigning any value to the Pasadena game is consistent with a certain standard set of axioms for decision theory. However, I suggest that it might be reasonable to believe that the value of an individual game is constrained by the long-run payout of repeated plays of the game. Although there is no value that repeated plays of the Pasadena game converges to in the standard strong sense, I show that there is a weaker sort of convergence (...) it exhibits, and use this to define a notion of ‘weak expectation’ that can give values to the Pasadena game and many others, though not to all games that fail to have a strong expectation in the standard sense.

To answer the question of whether mathematics needs new axioms, it seems necessary to say what role axioms actually play in mathematics. A first guess is that they are inherently obvious statements that are used to guarantee the truth of theorems proved from them. However, this may neither be possible nor necessary, and it doesn’t seem to fit the historical facts. Instead, I argue that the role of axioms is to systematize uncontroversial facts that mathematicians can accept from a wide (...) variety of philosophical positions. Once the axioms are generally accepted, mathematicians can expend their energies on proving theorems instead of arguing philosophy. Given this account of the role of axioms, I give four criteria that axioms must meet in order to be accepted. Penelope Maddy has proposed a similar view in Naturalism in Mathematics, but she suggests that the philosophical questions bracketed by adopting the axioms can in fact be ignored forever. I contend that these philosophical arguments are in fact important, and should ideally be resolved at some point, but I concede that their resolution is unlikely to affect the ordinary practice of mathematics. However, they may have effects in the margins of mathematics, including with regards to the controversial “large cardinal axioms” Maddy would like to support. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.4 (2003) 379-383 [Access article in PDF] Husserl at the Limits of Phenomenology: Including Texts by Edmund Husserl. Maurice Merleau-Ponty. Ed. Leonard Lawlor with Bettina Bergo. Trans. Leonard Lawlor. Evanston, IL: Northwestern University Press, 2002. Pp. 192. $19.95 pbk. The most striking characteristic of this volume is the manner that it presents layers of interpretation to the reader, particularly in that the writing is not intended (...) as a postmodern fête, and has limited value as a hermeneutic enterprise. Ultimately the book's true contribution is the seventy-nine pages devoted to the translation and printing of lecture notes used by [End Page 379] Merleau-Ponty in a class he gave at College de France, shortly before his death. However, the explanation of why this is so will have to be withheld until the end of this review.The course that Merleau-Ponty gave was organized around three essays published by Edmund Husserl. These essays are included in the volume reviewed here and must be briefly dealt with, as they are the core of whatever thinking occurs within and around this book. Interesting essays all, they deal with three longstanding issues of philosophical debate. The first essay challenges the classical notion of a transcendent ideal. Husserl attempts to show, through an examination of geometry, that an ideal is first called into existence when it is called into the realm of human experience, and he does this without ever resorting to the quality of detached being that Plato attributes to ideals. Then, in his second essay, Husserl attempts to defeat modernist cosmology, arguing, against Galileo, that the earth is a fixed point in the universe. Finally, his third essay hearkens back to Heraclitus and Parmenides, examining how human experience is able to extract a sense of atemporal quiddity in a world that is constantly falling into a past. A reader might be baffled that an intellectual could make such claims, but they are made from within the framework of phenomenology, and, within this paradigm as Husserl explains it, the claims he makes do not seem ridiculous at all. "The Origins of Geometry," "The Originary Ark, The Earth, Does Not Move," and "The World of the Living Present,"— these are the three essays that Merleau-Ponty forms his lecture course around. At sixty pages within this volume, they constitute one third of the text itself. For intellectual worth, I would say that these essays are the finest contribution in the text, but that claim is discounted because much of the essay material was already available in English translation. Nevertheless, it only makes sense to have it included in this volume in order to conveniently work back and forth between Merleau-Ponty's notes and Husserl's actual essays.However, that brings us to a significant problem within the text itself. If readers are like me, they will realize that it is often difficult to draw conclusions from the notes of others. Like secretarial shorthand, notes rely on a reader's ability to read both what has been written and what has been withheld in an expressive passage. There is no code that will allow us to recover what Merleau-Ponty recovered as he looked down on his podium at these notes and then raised his head to speak to his class. All that we have are the fragments, and they do not make a coherent argument, lacking both the clarity and the painstaking thoroughness that we find in books [End Page 380] such as The Phenomenology of Perception and The Visible and the Invisible. Certainly one cannot fault Merleau-Ponty for this—he did not write these notes for us, but for himself. His course might have been magnificent, even transcendent, but we will not know that from these fragments.I suppose it could be argued that the ambiguity inherent in such fragments liberates the text and opens it for some sort of radical hermeneutic exegesis; however, I sigh at the very thought of such an argument. Unless we intend to transform... (shrink)

Written by a team of distinguished scholars, this is an authoritative and comprehensive history of Western philosophy from its earliest beginnings to the present day. Illustrated with over 150 color and black-and-white pictures, chosen to illuminate and complement the text, this lively and readable work is an ideal introduction to philosophy for anyone interested in the history of ideas. From Plato's Republic and St. Augustine's Confessions through Marx's Capital and Sartre's Being and Nothingness, the extraordinary philosophical dialogue between great Western (...) minds has flourished unabated through the ages. Dazzling in its genius and breadth, the long line of European and American intellectual discourse tells a remarkable story--a quest for truth and wisdom that continues to shape our most basic ideas about human nature and the world around us. That quest is brilliantly brought to life in The Oxford History of Western Philosophy. With spectacular illustrations--including sixteen pages of full-color plates--this splendidly written volume takes the reader on a magnificient chronological tour through the revolutions of thought that have forged the Western philosophical tradition from ancient times to the present. Throughout, the six contributors--an internationally renowned team of philosophers including Roger Scruton, Anthony Quinton, and Anthony Kenny--bring the astonishingly diverse, wide-ranging landscape of intellectual history into sharp focus, emphasizing how notions seen today as part of an inevitable march of ideas were in their own time often considered radical, if not revolutionary. Thus we are treated, for example, to lively accounts of how Plato's "theory of forms" and Aristotle's pioneering exercises in logic broke with the past to irrevocably alter the course of Western thought. The authors also reveal the relationships between landmark thinkers, and the ways they drew on their intellectual heritage. They show, for instance, how St. Augustine and Aquinas, though advancing the cause of Christian doctrine, picked up where their pagan Greek forebears had left off. We witness how, during the Renaissance, the profound empiricist ideas underlying Descarte's famous utterance--"I think, therefore I exist"--lived in a tense but complementary relationship with Locke's rationalist theories. Moving into the eighteenth and nineteenth centuries, the book explores how Hume greatly influenced Kant's conception of the "transcendental aesthetic," and how Hegel drew upon the lesser known (but groundbreaking) work of Fichte and Schelling. The authors bring the story up to our own time, vividly recounting the existential trend from Nietzsche ("God is dead") to Sartre, along with other increasingly fractious schools of thought. Along the way, we not only encounter the vast intellectual riches of the Western mind, but we also meet the personalities behind the great thoughts, from the saintly Hume (described by Adam Smith as having "come as near to perfection as anybody could") to the ill-mannered outcast Fichte. And the hundreds of maps and striking illustrations (including full-color reproductions of art ranging from medieval manuscripts to the works of Raphael, Ingres, and Magritte) form an integral part of the book, revealing the interweaving of art and ideas through the ages, as artists have striven to give visual immediacy to philosophical concepts. The Oxford History of Western Philosophy is the most authoritative single-volume account ever written for the general reader. Engagingly written and astonishingly far-reaching, it provides the consummate introduction to the intellectual bedrock upon which Western civilization is built. (shrink)

In this book Larry Temkin examines the concepts of equality and inequality, and addresses one particular question in depth: how can we judge between different sorts of inequality? When is one inequality worse than another? Temkin shows that there are many different factors underlying and influencing our egalitarian judgments and that the notion of inequality is surprisingly complex. He looks at inequality as applied to individuals and to groups, and at the standard measures of inequality employed by economists and (...) others, and considers whether inequality matters more in a poor society than a rich one. The arguments of non-egalitarians are also examined. Temkin's book presents a new way of thinking about equality and inequality which challenges the assumptions of philosophers, welfare economists, and others concerned with these notions on a practical as well as a theoretical level.

Unethical conduct has reached crisis proportions in business :A1–A10, 2011) and on today’s college campuses :58–65, 2007). Despite the evidence that suggests that more than half of business students admit to dishonest practices, only about 5 % of business school deans surveyed believe that dishonesty is a problem at their schools :299–308, 2010). In addition, the AACSB which establishes standards for accredited business schools has resisted the urging of deans and business experts to require business schools to teach an ethics (...) class, and fewer than one-third of businesses schools now teach a business ethics course at the graduate or undergraduate levels. In this paper we briefly introduce the status of business ethics education and report the results of a survey of business students, deans of the top business schools, and business ethics subject matter experts about ten ethical outcomes. We then offer five specific recommendations to encourage business ethics faculty and decision makers to improve the teaching of business ethics. (shrink)

This short but highly ambitious book asks us to rethink the evolution of the ideas on which modern states are built. Larry Siedentop argues that the core of what is now our system of beliefs, liberalism, emerged much earlier than generally recognised, established not in the Renaissance but by the arguments of lawyers and philosophers in the twelfth and thirteenth centuries. There are large parts of the world--fundamentalist Islam; quasi-capitalist China--where other belief systems flourish.

A volume on nature, ingredients, causes and consequences of human happiness by father and son team of Antony and Charles Kenny.

Bayesians standardly claim that there is rational pressure for agents’ credences to cohere across time because they face bad (epistemic or practical) consequences if they fail to diachronically cohere. But as David Christensen has pointed out, groups of individual agents also face bad consequences if they fail to interpersonally cohere, and there is no general rational pressure for one agent's credences to cohere with another’s. So it seems that standard Bayesian arguments may prove too much. Here, we agree with Christensen (...) that there is no general rational pressure to diachronically cohere, but we argue that there are particular cases in which there is rational pressure to diachronically cohere, as well as particular cases in which interpersonal probabilistic coherence is rationally required. More generally, we suggest that Bayesian arguments for coherence apply whenever a collection (of agents or time slices) has a shared dimension of value and an ability to coordinate their actions in a range of cases relevant to that value. Typically, this shared value and ability to coordinate is very strong across the time slices of one human being, and very weak across different human beings, but there are special cases where these can switch—i.e., some groups of humans will have as much reason for their beliefs to cohere across a particular range of cases as the time slices of one human usually do, but some time slices of a human will have as much freedom to differ in their beliefs from the others as the members of a group usually do.
