By means of multi-agent simulations, it investigates the truth and consensus-conduciveness of controversial debates. The book brings together research in formal epistemology and argumentation theory.

The U.S. scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. These scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers. -/- Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and (...) scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly-some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it. -/- Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

In this important new book Nagel, one of the most distinguished philosophers writing in English today, presents a sustained defence of reason against the attacks of subjectivism. He offers systematic rebuttals of relativistic claims with respect to language, logic, science, and ethics.

This book is the first systematic treatment of 'responsibilist' or character-based virtue epistemology, an approach to epistemology that focuses on intellectual ...

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a regress (...) of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem. (shrink)

"The book’s contribution to feminist philosophy of religion is substantial and original.... It brings the continental and Anglo-American traditions into substantive and productive conversation with each other." —Ellen Armour To what extent has the emergence of the study of religion in Western culture been gendered? In this exciting book, Grace Jantzen proposes a new philosophy of religion from a feminist perspective. Hers is a vital and significant contribution which will be essential reading in the study of religion.

Argues that role obligations are not marginal, "that they are central to morality and should be taken seriously." "A 'role obligation' is a moral requirement, which attaches to an institutional role, whose content is fixed by the function of the role, and whose normative force flows from the role." Rejects what he calls the doctrine of perfect adequacy which holds that role obligations are both comprehensive and transparent. Although this may have been plausible at earlier times, it is clearly implausible (...) now. It is the implausibility of this doctrine which has led theorists to accept the standard view: which holds that role obligations that are noncontractual are extremely problematic. Once we reject the doctrine of perfect adequacy, however, we can see the significance of role obligations more clearly. [The content of role obligations, Hardimon admits, is indeterminate in the sense that it is subject to constructive interpretation. This suggests, however, that the obligations are not the source of their normative power, rather it is their justifying value which explains why some role requirements are obligatory. This is confirmed by the rest of the article.] One thing that should lead us to question the notion that we do not have obligations of this sort by considering what it would be like to have no noncontractual role obligations. [This, however, does not establish that the force of role obligations flows from the obligations themselves.] One objection to NCR obligations is that they may require acting in accordance with an unjust institution. However, the solution here is the same as with contractual obligations: unjust institutions and contracts do not bind. Moves on to identity. "What I am assuming is that most of us do at least tacitly conceive of ourselves as family members and citizens, that these self-understandings are central to our own general self-conception, and that we can, through reflection come to recognize that we do in fact conceive of ourselves in these ways. If this is correct, then abandoning the idea that we have noncontractual role obligations would require radical revision of our self-conception, for we cannot give up the idea of nonctractual role obligation without also ceasing to conceive of ourselves as family members and citizens. What, after all, would it mean to say that we conceive of ourselves as family members but regard oursleves as having no familial obligations whatsoever?...The upshot of the last two paragraphs is that the cost of abandoning our conception of ourselves as family members and citizens would be enormous." [The moral significance of identity is unclear here - is the only normative element loss of identity with rejection of role obligations? What of the case when one's identity is caught up in a role which requires one to act immorally in other ways?] If impressment is our concern, it shouldn't be, for role obligations are not like impressment - one is born into them, not impressed [how does this make a difference?]. Role must be reflectively acceptable to produce genuine obligations. "Determining whether a given social role is reflectively acceptable involves stepping back from that role in thought and asking whether it is a role people ought to occupy and play. Determining that a given social role is reflectively acceptable involves judging that it is meaningful, rational, or good." [Hence, some independent value is going to do all the work for role obligations - the normative force of a role does not flow from the role itself.] Concerning voluntary roles - even if we agree that voluntary acceptance is essential, this omits important elements of role identification. "The key component of the idea of identifying with a role is that of conceiving of oneself as someone for whom the norms, that is, the evaluative standards associated with a role, its rights, duties, virtues, ideals, and supererogations, have reason-giving force. Here is the idea. If you identify with a role, its norms will function for you as reasons. If you are a judge who identifies with the role of judge, the fact that this is something judges do will give you a reason for doing it." [Clearly a non-sequiter - conceiving of oneself as having a reason does not give oneself a reason for doing - there must actually be a reason for doing something. Moreover, the content of the role may be in question - and here we are to engage in constructive interpretation, which is just to say that we are to identify some underlying value and this will serve to justify and determine the content of the role. Refers to usage of "look, its your job" as basis for substantiating claims about the normative force of identity. "But here a basic point of similarity emerges between contractual and noncontractual role obligations. People can and do identify with their noncontractual roles and not just with their contractual roles. And when they do, assuming that the appropriate background moral conditions are in place, the fact taht they occupy these roles will provide them with reasons for carrying out the tasks of their noncontractual roles...The basic form of motivation provided by identification with contractual and noncontractual role obligations is the same.".

This chapter aims to provide materials with which to substantiate the claim that, under the appropriate circumstances, the notion of analyticity can help explain how one might have a priori knowledge even in the strong sense. It argues that Implicit Definition, properly understood, is completely independent of any form of irrealism about logic. The chapter defends the thesis of Implicit Definition against Quine's criticisms, and examines the sort of account of the apriority of logic that this doctrine is able to (...) provide. The chapter shows that, against the background of a rejection of indeterminacy, its insolubility cannot be conceded. It also argues that neither a non‐factualism about Frege‐analyticity, nor an error thesis about it, can plausibly fall short of an outright rejection of meaning itself. The chapter shows how the doctrine that appears to offer the most promising account of how we grasp the meanings of the logical constants. (shrink)

Why do so many people believe in psychic phenomena? Because they have psychic experiences. And why do they have psychic experiences? Because such experiences are an inevitable consequence of the way we think. I suggest that, like visual illusions, they are the price we pay for a generally very effective relationship with a massively complex world.

In this paper I aim to show that the creation and manipulation of written vehicles is part of our cognitive processing and, therefore, that writing transforms our cognitive abilities. I do this from the perspective of cognitive integration: completing a complex cognitive, or mental, task is enabled by a co-ordinated interaction between neural processes, bodily processes and manipulating written sentences. In section one I introduce Harris’ criticisms of ways in which writing has been said to restructure thought (Goody 1968; McLuhan (...) 1962, 1964; Ong 1982). This will give us a preliminary idea about possible pitfalls for a cognitive integrationist account. The second section outlines, firstly, how integrated cognitive systems function. Secondly, the model is applied to a hybrid mental act where writing allows us to complete complex cognitive tasks. The final section outlines the sense in which, following Harris, there is “a more realistic picture of how writing restructures thought” [Harris, R., 1989. How does writing restructure thought? Language and Communication 9 (2/3) 99–106] that is concealed by the ‘romantic fantasies’ of theorists such as the above. This picture is one of writing providing an autoglottic space in which a new form of theoretical thinking becomes prevalent. The cognitive integrationist understands this in terms of the nature of the written vehicles and how we manipulate them. (shrink)

Most professions rest on the expertise of their members. Professionals are professionals primarily because they know more than most of us about something of importance to our society or to many members of it. Professionals are given power, respect, prestige, and above average incomes. If professionals are worthy of this status, it is largely because of their special knowledge and the way they use it. And if professionals have special rights and responsibilities, it is also primarily because of the social (...) positions they occupy due to their presumed expertise. (shrink)

My conclusion will be that, more often than we might have thought, suspension of judgment is the epistemically proper attitude. It follows that in such cases we lack reasonable belief and so, at least on standard conceptions, knowledge. This is a kind of contingent real-world skepticism that has not received the attention it deserves. I hope that this paper will help to bring this issue to life.

The phenomenon of persistent ethical disagreement is often cited in connection with the question of whether there is any ‘‘absolute’’ morality, or whether, instead, morality is in some sense merely ‘‘a matter of personal opinion’’. Citing disagreement, many people who hold strong views about controversial issues such as the permissibility of abortion, eating meat, or the death penalty deny that these views are anything more than ‘‘personal beliefs’’. But while there might be inconsistencies lurking in this position, it is not (...) obviously at fault for according the facts about disagreement some epistemic weight. This paper addresses the question of whether and to what extent moral disagreement undermines moral knowledge. The most familiar arguments from disagreement in the literature purport to establish conclusions about the metaphysics of morality: that there are no moral facts, or that there are no moral properties, or that the moral facts are relative rather than absolute. Of course, the conclusions of some such metaphysical arguments might be perfectly consistent with the existence of considerable moral knowledge. For example, even if there is some successful argument from disagreement to the conclusion that moral facts are relative rather than absolute, this might very well be consistent with our having just as much moral knowledge as we..

Responding rationally to the information that others disagree with one’s beliefs requires assessing the epistemic credentials of the opposing beliefs. Conciliatory accounts of disagreement flow in part from holding that these assessments must be independent from one’s own initial reasoning on the disputed matter. I argue that this claim, properly understood, does not have the untoward consequences some have worried about. Moreover, some of the difficulties it does engender must be faced by many less conciliatory accounts of disagreement.

This paper explores the sense in which belief "aims at the truth". In this course of this exploration, it discusses the difference between belief and make-believe, the nature of psychoanalytic explanation, the supposed "normativity of meaning", and related topics.

Manipulative actions come in a bewildering variety of forms: direct and indirect deception, playing on emotions, tempting, inciting, and so on. It is not obvious what feature all these actions share in virtue of which they are all of the same kind and in virtue of which they are all morally wrong. This article argues that all manipulative actions are cases in which the manipulator attempts to lead the victim astray by trying to get her to have emotions, beliefs, or (...) desires that, as the manipulator sees it, are not ideal for the victim. To attempt to lead a person astray in this way is to fail to respect the moral and rational agency of the victim. This analysis captures the fact that actions of many kinds--and with many different psychological effects--can be manipulative, and it tells us what is wrong with acting manipulatively. It also helps distinguish manipulation from non rational persuasion. (shrink)

This paper argues for two theses: that degrees of belief are context sensitive; that outright belief is belief to degree 1. The latter thesis is rejected quickly in most discussions of the relationship between credence and belief, but the former thesis undermines the usual reasons for doing so. Furthermore, identifying belief with credence 1 allows nice solutions to a number of problems for the most widely-held view of the relationship between credence and belief, the threshold view. I provide a sketch (...) of a formal framework on which both theses are true. This is a modified Bayesian framework; I argue that despite making credences context-sensitive, the framework lets Bayesians hold on to their signature explanatory successes. The sort of context-sensitivity claimed for credences here mirrors the sort of context-sensitivity I have elsewhere claimed for outright belief: one's credences depend, in part, on the space of alternative possibilities one takes seriously in a context.

Open-mindedness appears to be a cognitive disposition: an open-minded person is disposed to gain, lose, and revise beliefs in a particular, reasonable way. It is also a moral virtue, for we blame, for example, the man who quickly comes to think a new neighbor untrustworthy because he drives the wrong car or wears the wrong clothes—for his closed-mindedness. How open–mindedness could be a moral virtue is a puzzle, though, because exercises of moral virtues are expressions of moral concern, whereas gaining, (...) losing, and revising beliefs are not actions and so cannot be actions taken out of moral concern. Solving this puzzle is the purpose of this essay. (shrink)

In her 1997 OSSA paper, Trudy Govier discusses in detail my thesis that arguers have dialectical obligations. In a 1998 paper she further examines this thesis to see whether it is viable and concludes that it faces serious problems. In this paper, I assess the state of the thesis in light of Govier's discussion of it. I urge that we have something to gain from the empirical turn--from investigating best practices. At the end, I take a step back to ask (...) what is really at issue here and how it connect s to other issues in the theory of argument. (shrink)

This is the text of The Lindley Lecture for 2009, given by Allan Gibbard, an American philosopher.

In this paper I explore Ralph Johnson's proposal that in addition to premises and conclusion every argument should have a dialectical tier in which the arguer addresses objections to the argument, and considers alternative positions. After exploring several reasons for thinking that Johnson's proposal is a good one, I then raise a number of objections against it and move ahead to respond to those objections, which I do by distinguishing making out a case for a conclusion from offering an argument (...) for it, and distinguishing supplementary arguments from one's main argument. I contend that it is not realistic to see arguers as having an obligation to respond to all objections and to address all alternative positions; we must somehow discriminate those which need and merit a reply from those which do not.

Book synopsis: The only anthology devoted exclusively to the topic of pornography and censorship that is designed as a textbook. Its aim is threefold: To make students aware of the vast scope of arguments concerning both the nature of pornography and what ought to be done about it; the fact that there is more than one feminist position on pornography; and the complexity of arguments about free speech. Balanced and up-to-date, the book is sensitive to the variety of feminist positions (...) on pornography without being a feminist book and is also sensitive to the complexity of free speech issues.

Experiments show that psi differs from known physical processes in a variety of ways, and these differences are described herein. Because of these, psi cannot be accounted for in terms of presently known physical laws. A number of theories, of which we review a sampling, suggest ways in which known physical laws might be expanded in order to account for psi. However, there is no agreement on which of these theories, if any, will ultimately provide a general explanation. A further (...) problem in studying psi is that it is elusive, i.e., methods are not presently known by which it can be reliably produced. However, if psi is real, its study can open the door to a new frontier of knowledge and contribute to our understanding of consciousness. (shrink)
