Traditional definitions of lying require that a speaker believe that what she asserts is false. Sam Fox Krauss seeks to jettison the traditional belief requirement in favour of a necessary condition given in a credence-accuracy framework, on which the liar expects to impose the risk of increased inaccuracy on the hearer. He argues that this necessary condition importantly captures nearby cases as lies which the traditional view neglects. I argue, however, that Krauss's own account suffers from an identical drawback of (...) being unable to explain nearby cases; and even worse, that account fails to distinguish cases of telling lies from cases of telling the truth.

Almost all philosophers agree that a necessary condition on lying is that one says what one believes to be false. But, philosophers haven’t considered the possibility that the true requirement on lying concerns, rather, one’s degree-of-belief. Liars impose a risk on their audience. The greater the liar’s confidence that what she asserts is false, the greater the risk she’ll think she’s imposing on the dupe, and, therefore, the greater her blameworthiness. From this, I arrive at a dilemma: either the belief (...) requirement is wrong, or lying isn’t interesting. I suggest an alternative necessary condition for lying on a degree-of-belief framework.

What does it mean to be truthful? What role does truth play in our lives? What do we lose if we reject truthfulness? No philosopher is better suited to answer these questions than Bernard Williams. Writing with his characteristic combination of passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine.Modern culture exhibits two attitudes toward truth: suspicion of being deceived and skepticism that objective truth exists at (...) all. This tension between a demand for truthfulness and the doubt that there is any truth to be found is not an abstract paradox. It has political consequences and signals a danger that our intellectual activities, particularly in the humanities, may tear themselves to pieces.Williams's approach, in the tradition of Nietzsche's genealogy, blends philosophy, history, and a fictional account of how the human concern with truth might have arisen. Without denying that we should worry about the contingency of much that we take for granted, he defends truth as an intellectual objective and a cultural value. He identifies two basic virtues of truth, Accuracy and Sincerity, the first of which aims at finding out the truth and the second at telling it. He describes different psychological and social forms that these virtues have taken and asks what ideas can make best sense of them today. Truth and Truthfulness presents a powerful challenge to the fashionable belief that truth has no value, but equally to the traditional faith that its value guarantees itself. Bernard Williams shows us that when we lose a sense of the value of truth, we lose a lot both politically and personally, and may well lose everything. (shrink)

We examine in detail three classic reasoning fallacies, that is, supposedly ``incorrect'' forms of argument. These are the so-called argumentam ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument. In each case, the argument type is shown to match structurally arguments which are widely accepted. This suggests that it is not the form of the arguments as such that is problematic but rather something about the content of those examples with which they are typically justified. This (...) leads to a Bayesian reanalysis of these classic argument forms and a reformulation of the conditions under which they do or do not constitute legitimate forms of argumentation. (shrink)

In the philosophical debate on lying, there has generally been agreement that either the speaker believes that his statement is false, or he believes that his statement is true. This article challenges this assumption, and argues that lying is a scalar phenomenon that allows for a number of intermediate cases – the most obvious being cases of uncertainty. The first section shows that lying can involve beliefs about graded truth values (fuzzy lies) and graded beliefs (graded-belief lies). It puts forward (...) a new definition to deal with these scalar parameters, that requires that the speaker asserts what he believes more likely to be false than true. The second section shows that statements are scalar in the same way beliefs are, and accounts for a further element of scalarity, illocutionary force. (shrink)

We have good reason to condemn lying more strongly than misleading and to condemn bullshit assertion less harshly than lying but more harshly than misleading. We each have good reason to mislead rather than make bullshit assertions, but to make bullshit assertions rather than lie. This is because these forms of deception damage credibility in different ways. We can trust the misleader to assert only what they believe to be true. We can trust the bullshitter not to assert what they (...) believe to be false. We cannot trust the liar at all. (shrink)

Ambitious and elegant, this book builds a bridge between evolutionary theory and cultural psychology. Michael Tomasello is one of the very few people to have done systematic research on the cognitive capacities of both nonhuman primates and human children. The Cultural Origins of Human Cognition identifies what the differences are, and suggests where they might have come from. -/- Tomasello argues that the roots of the human capacity for symbol-based culture, and the kind of psychological development that takes place within (...) it, are based in a cluster of uniquely human cognitive capacities that emerge early in human ontogeny. These include capacities for sharing attention with other persons; for understanding that others have intentions of their own; and for imitating, not just what someone else does, but what someone else has intended to do. In his discussions of language, symbolic representation, and cognitive development, Tomasello describes with authority and ingenuity the "ratchet effect" of these capacities working over evolutionary and historical time to create the kind of cultural artifacts and settings within which each new generation of children develops. He also proposes a novel hypothesis, based on processes of social cognition and cultural evolution, about what makes the cognitive representations of humans different from those of other primates. -/- Lucid, erudite, and passionate, The Cultural Origins of Human Cognition will be essential reading for developmental psychology, animal behavior, and cultural psychology.

In this provocative book, a professor of philosophy examines the arguments for and against euthanasia, analyzes specific case studies, including those of Baby Jane Doe and Barney Clark, and offers an alternate theory on the morality of euthanasia. Various traditional distinctions--between "human" and "non-human," intentional and nonintentional, killing and "letting die"--are taken into account to determine whether euthanasia is permissible or not. Rachels presents a systematic argument against the traditional view, defending an alternative position based on the belief that there (...) is a profound difference between having a life and merely being alive.

A "slippery slope argument" is a type of argument in which a first step is taken and a series of inextricable consequences follow, ultimately leading to a disastrous outcome. Many textbooks on informal logic and critical thinking treat the slippery slope argument as a fallacy. Walton argues that used correctly in some cases, they can be a reasonable type of argument to shift a burden of proof in a critical discussion, while in other cases they are used incorrectly. Walton identifies (...) and analyzes four types of slippery slope argument. Walton presents guidelines that show how each type of slippery slope argument can be used correctly or incorrectly, using over fifty case studies of argumentation on controversial issues. These include abortion, medical research on human embryos, euthanasia, the decriminalization of marijuana, pornography, and censorship, and banning of American flag burning. (shrink)

Bayes' Theorem is a simple mathematical formula used for calculating conditional probabilities. It figures prominently in subjectivist or Bayesian approaches to epistemology, statistics, and inductive logic. Subjectivists, who maintain that rational belief is governed by the laws of probability, lean heavily on conditional probabilities in their theories of evidence and their models of empirical learning. Bayes' Theorem is central to these enterprises both because it simplifies the calculation of conditional probabilities and because it clarifies significant features of subjectivist position. Indeed, (...) the Theorem's central insight — that a hypothesis is confirmed by any body of data that its truth renders probable — is the cornerstone of all subjectivist methodology. (shrink)

I argue that lying is generally morally better than mere deliberate misleading because the latter involves the exploitation of a greater trust and more seriously abuses our willingness to fulfil epistemic and moral obligations to others. Whereas the liar relies on our figuring out and accepting only what is asserted, the mere deliberate misleader depends on our actively inferring meaning beyond what is said in the form of conversational implicatures as well. When others’ epistemic and moral obligations are determined by (...) standard assumptions of communicative cooperation and no compelling moral reason justifies mere deliberate misleading instead, one had better lie.

In the philosophical literature on the definition of lying, the analysis is generally restricted to cases of flat-out belief. This chapter considers the complex phenomenon of lies involving partial beliefs – beliefs ranging from mere uncertainty to absolute certainty. The first section analyses lies uttered while holding a graded belief in the falsity of the assertion, and presents a revised insincerity condition, requiring that the liar believes the assertion to be more likely to be false than true. The second section (...) analyses assertions that express graded beliefs, exploring how mitigation and reinforcement can alter the insincerity conditions for lying. The last section considers the case of lies that attack certainty (knowledge-lies), understood as attempt to alter the hearer's graded beliefs. (shrink)

In this essay I will argue, as does Bernard Williams, that lying and misleading are both commonly wrong because they involve an aim to breach a trust. I will also argue, contrary to Williams, that lying and misleading threaten trust differently, and that when they are wrong, they are wrong differently. Indeed, lying may be wrong when misleading is not.

Edwin Hartman argues that ethical principles should not derive from abstract theory, but from the real world of experience in organizations. He explains how ethical principles derive from what workers learn in their communities (firms), and that an ethical firm is one that creates the good life for the workers who contribute to its mission. His approach is based on the Aristotelian tradition of refined common sense, from recent work on collective action problems in organizations, and from social contract theory.

Few moral questions have greater bearing on the conduct of our everyday lives than questions about the morality of lying. These questions are also important for ethical theory. An important test of any theory of right and wrong is whether it gives an adequate account of the morality of lying. Conceptual questions about the nature of lying are prior to questions about the moral status of lying. Any theory about the moral status of lying presupposes an account of what lying (...) is.

"Like Dewey, he has revolted against the empiricist dogma and the Kantian dualisms which have compartmentalized philosophical thought.... Unlike Dewey, he has provided detailed incisive argumentation, and has shown just where the dogmas and dualisms break down." --Richard Rorty, _The Yale Review_.

What is the nature of moral behavior? According to the study of bounded rationality, it results not from character traits or rational deliberation alone, but from the interplay between mind and environment. In this view, moral behavior is based on pragmatic social heuristics rather than moral rules or maximization principles. These social heuristics are not good or bad per se, but solely in relation to the environments in which they are used. This has methodological implications for the study of morality: (...) Behavior needs to be studied in social groups as well as in isolation, in natural environments as well as in labs. It also has implications for moral policy: Only by accepting the fact that behavior is a function of both mind and environmental structures can realistic prescriptive means of achieving moral goals be developed.

I analyze three forms of the slippery slope argument (two logical and one empirical) using two questions: 1) in the context of what kind of norms are we considering a first step on a possible slope: statute law, precedent law, positive morality, or critical morality? 2) What is meant by "If we allow this first step"? The conclusion is that the argument's greatest force is in a context of institutionalized norms, like law, whereas its importance in morality is only marginal.

This paper is a critical examination of the so-called slippery slope argument for the conservative position on abortion. The argument was discussed in the philosophic literature some time back, but has since fallen into disfavor. The argument is first exposed and a general objection to it is advanced, then rebutted. Rosalind Hursthouse's more detailed and stronger objection is next aired, but also found less than convincing. In the course of discussing her objection, the correct form of the argument is identified, (...) and it's noted that rejection of the argument requires finding fault with its inductive premise. That, in turn, requires either (a) identifying and defending a cutoff point other than conception, or (b) not identifying a cutoff point but directly attacking the argument's conclusion. As far as (a) is concerned, all except one alternative cutoff point have severe problems that have been well discussed in the literature. The one that doesn't, the appearance of the ‘primitive streak’, is examined in detailed, but ultimately rejected. As for (b), five different grounds for rejecting the conclusion are identified and discussed, but none is found plausible. Variations on the slippery slope argument, concerning different conclusions that it may have, are then distinguished, related to each other, and critically discussed, and the paper ends with some cautionary remarks about the defense of the argument tendered.

A slippery slope argument is an argument to this twofold effect. First, that if a policy or practice P is permitted, then we lack the dialectical resources to demonstrate that a similar policy or practice P* is not permissible. Since P* is indeed not permissible, we should not endorse policy or practice P. At the heart of such arguments is the idea of dialectical impotence, the inability to stop the acceptance of apparently small deviations from a heretofore secure policy or (...) practice from leading to apparently large and unacceptable deviations. Using examples of analogical arguments and sorites arguments I examine this phenomenon in the context of collapsing taboos. (shrink)
