Walton gives a clear method for analyzing and evaluating cases of ad hominem arguments found in everyday argumentation.

The Systematicity Arguments is the only book-length treatment of the systematicity and productivity arguments.

According to First-Person Realism, one's own first-person perspective on the world is metaphysically privileged in some way. After clarifying First-Person Realism by reference to parallel debates in the metaphysics of modality and time, I survey eight different arguments in favor of First-Person Realism.

Ad hominem arguments argue that some opponent should not be heard and no argument of that opponent should be heard or considered. The opponent has generally pernicious views, false and harmful. Moreover he is diabolically clever at arguing for his views. Thus, the ad hominem argument is essentially a device by which non-intellectuals try to wrest control of a dialectical situation from intellectuals. Stifling intellectuals, disrupting the dialectical situation, is an unpleasant conclusion, but no fallacy has been shown in (...) what leads up to that conclusion. (shrink)

Many philosophers believe that our ordinary English words man and woman are “gender terms,” and gender is distinct from biological sex. That is, they believe womanhood and manhood are not defined even partly by biological sex. This sex/gender distinction is one of the most influential ideas of the twentieth century on the broader culture, both popular and academic. Less well known are the reasons to think it’s true. My interest in this paper is to show that, upon investigation, the (...) class='Hi'>arguments for the sex/gender distinction have feet of clay. In fact, they all fail. We will survey the literature and tour arguments in favor of the sex/gender distinction, and then we’ll critically evaluate those arguments. We’ll consider the argument from resisting biological determinism, the argument from biologically intersex people and vagueness, the argument from the normativity of gender, and some arguments from thought experiments. We’ll see that these arguments are not up to the task of supporting the sex/gender distinction; they simply don’t work. So, philosophers should either develop stronger arguments for the sex/gender distinction, or cultivate a variety of feminism that’s consistent with the traditional, biologically-based definitions of woman and man.

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our (...) object beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

This book is a unique contribution to the philosophy of religion. It offers a comprehensive discussion of one of the most famous arguments for the existence of God: the ontological argument. The author provides and analyses a critical taxonomy of those versions of the argument that have been advanced in recent philosophical literature, as well as of those historically important versions found in the work of St Anselm, Descartes, Leibniz, Hegel and others. A central thesis of the book is (...) that ontological arguments have no value in the debate between theists and atheists. There is a detailed review of the literature on the topic (separated from the main body of the text) and a very substantial bibliography, making this volume an indispensable resource for philosophers of religion and others interested in religious studies.

It is common in various quarters of philosophy to derive philosophically significant conclusions from theories of reference. In this paper, we argue that philosophers should give up on such 'arguments from reference.' Intuitions play a central role in establishing theories of reference, and recent cross-cultural work suggests that intuitions about reference vary across cultures and between individuals within a culture (Machery et al. 2004). We argue that accommodating this variation within a theory of reference undermines arguments from reference.

Traditional theistic arguments conclude that God exists. Pragmatic theistic arguments, by contrast, conclude that you ought to believe in God. The two most famous pragmatic theistic arguments are put forth by Blaise Pascal (1662) and William James (1896). Pragmatic arguments for theism can be summarized as follows: believing in God has significant benefits, and these benefits aren’t available for the unbeliever. Thus, you should believe in, or ‘wager on’, God. This article distinguishes between various kinds of (...) theistic wagers, including finite vs. infinite wagers, premortem vs. postmortem wagers, and doxastic vs. acceptance wagers. Then, we’ll turn to the epistemic-pragmatic distinction, and discusses the nuances of James’ argument, and how views like epistemic permissivism and epistemic consequentialism provide unique “hybrid” wagers. Finally, we’ll cover outstanding objections and responses. (shrink)

Fourteen new essays by a distinguished team of authors offer a broad and stimulating re-examination of transcendental arguments. This is the philosophical method of arguing that what is doubted or denied by the opponent must be the case, as a condition for the possibility of experience, language, or thought.The line-up of contributors features leading figures in the field from both sides of the Atlantic; they discuss the nature of transcendental arguments, and consider their role and value. In particular, (...) they consider how successful such arguments are as a response to sceptical problems. The editor's introduction provides historical context and philosophical orientation for the discussions. This is the first major appraisal of transcendental arguments since the 1970s; they have continued to play a significant role in philosophy, and recent developments in epistemology and metaphysics have raised new questions and challenges for them. Transcendental Arguments will be essential reading for anyone interested in this area of philosophy, and the starting-point for future work. (shrink)

In this crisply written book, Hanno Sauer offers the first book-length treatment of debunking arguments in ethics, developing an empirically informed and philosophically sophisticated account of genealogical arguments and their significance for the reliability of moral cognition. He breaks new ground by introducing a series of novel distinctions into the current debate, which allows him to develop a framework for assessing the prospects of debunking or vindicating our moral intuitions. He also challenges the justification of some of our (...) moral judgments by showing that they are based on epistemically defective processes. His book is an original, cutting-edge contribution to the burgeoning field of empirically informed metaethics, and will interest philosophers, psychologists, and anyone interested in how - and whether - moral judgment works.

The role of freedom in assigning moral responsibility is one of the deepest problems in metaphysics and moral theory. _Incompatibilism’s Allure_ provides original analysis of the principal arguments for incompatibilism. Ishtiyaque Haji incisively examines the consequence argument, the direct argument, the deontic argument, the manipulation argument, the impossibility argument and the luck objection. He introduces the most important contemporary discussions in a manner accessible to advanced undergraduates, but also suited to professional philosophers. The result is a unique and compelling (...) account for incompatibilism’s continuing allure. (shrink)

Four important arguments for probabilism—the Dutch Book, representation theorem, calibration, and gradational accuracy arguments—have a strikingly similar structure. Each begins with a mathematical theorem, a conditional with an existentially quantified consequent, of the general form: if your credences are not probabilities, then there is a way in which your rationality is impugned. Each argument concludes that rationality requires your credences to be probabilities. I contend that each argument is invalid as formulated. In each case there is a mirror-image (...) theorem and a corresponding argument of exactly equal strength that concludes that rationality requires your credences not to be probabilities. Some further consideration is needed to break this symmetry in favour of probabilism. (shrink)

_Arguments from Ignorance _explores the situations in which the argument from ignorance functions as a respectable form of reasoning and those in which it is indeed fallacious. Douglas Walton draws on everyday conversations on all kinds of practical matters in which the _argumentum ad ignorantiam _is used quite appropriately to infer conclusions. He also discusses the inappropriate use of this kind of argument, referring to various major case studies, including the Salem witchcraft trials, the McCarthy hearings, and the Alger Hiss (...) case. This book makes an original contribution in the areas of argumentation theory and informal logic, contending that, despite its traditional classification as a fallacy, the argument from ignorance is a genuine, very common, and legitimate type of argumentation with an identifiable structure. But the book is also interdisciplinary in scope, explaining many widely interesting and controversial subjects in artificial intelligence, medical education, philosophy of science, and philosophy of law in a clear way that makes it accessible to a broad range of readers.

<b>Objectives:</b> To gather empirical data on how gender and educational level influence bioethical reasoning among medical students by analyzing their use of care versus justice arguments for reconciling a bioethical dilemma. <b>Setting:</b> University Departments of Medical Ethics, Social and Communication Psychology in Germany. Participants: First and fifth year medical students. Design and method: Multidisciplinary, empirical, 2-segment study of ethics in action: In intrapersonal Segment 1, the students were presented with a bioethical dilemma and then administered a 13-item questionnaire to (...) survey their individual preferences for care versus justice arguments in resolving the conflict. The survey questioned 6 justice, 6 care-related items and 1 socially critical item. Data were analysed by gender and year of medical school. In interpersonal Segment 2, the bioethical dilemma from Segment 1 was discussed in gender-mixed and gender-homogeneous groups. Coded transcripts were evaluated to identify prevalences in care versus justice reasoning. <b>Results:</b> Data on 462 medical students were evaluable (n=338 in Segment 1, n=168 in Segment 2, n=44 overlap). Gender and level of education had no effect on moral reasoning in intrapersonal Segment 1, but significantly affected reasoning in interpersonal Segment 2, where women significantly tended to use more care-orientated arguments. Justice arguments predominated the group discussions. <b>Conclusion:</b> Interpersonal contexts affect moral reasoning in medical students, probably by amplifying the socialisation relating to gender and educational level. Care orientation is associated with the female gender. Professional socialisation tends to reduce the diversity and richness of moral reasoning towards a more justice-weighted orientation. Medical ethics should teach both justice and care reasoning modes in order to broaden physicians' ability to reconcile bioethical dilemmas. (shrink)

G. E. Moore famously argued against skepticism and idealism by appealing to their inconsistency with alleged certainties, like the existence of his own hands. Recently, some philosophers have offered analogous arguments against revisionary views about ethics such as metaethical error theory. These arguments appeal to the inconsistency of error theory with seemingly obvious moral claims like “it is wrong to torture an innocent child just for fun.” It might seem that such ‘Moorean’ arguments in ethics will stand (...) or fall with Moore’s own arguments in metaphysics and epistemology, in virtue of their shared structure. I argue that this is not so. I suggest that the epistemic force of the canonical Moorean arguments can best be understood to rest on asymmetries in indirect evidence. I then argue that this explanation suggests that Moorean arguments are less promising in ethics than they are against Moore’s own targets. I conclude by examining the competing attempt to vindicate Moorean arguments by appealing to Rawls’s method of reflective equilibrium. (shrink)

One result of successful argumentation – able arguers presenting cogent arguments to competent audiences – is a transfer of credibility from premises to conclusions. From a purely logical perspective, neither dubious premises nor fallacious inference should lower the credibility of the target conclusion. Nevertheless, some arguments do backfire this way. Dialectical and rhetorical considerations come into play. Three inter-related conclusions emerge from a catalogue of hapless arguers and backfiring arguments. First, there are advantages to paying attention to (...) arguers and their contexts, rather than focusing narrowly on their arguments, in order to understand what can go wrong in argumentation. Traditional fallacy identification, with its exclusive attention to faulty inferences, is inadequate to explain the full range of argumentative failures. Second, the notion of an Ideal Arguer can be defined by contrast with her less than ideal peers to serve as a useful tool in argument evaluation. And third, not all of the ways that arguers raise doubts about their conclusions are pathological. On the contrary, some ways that doubts are raised concerning our intended conclusions are an integral part of ideal argumentative practice. (shrink)

I offer a meta-level analysis of realist arguments for the reliability of ampliative reasoning about the unobservable. We can distinguish form-driven and content-driven arguments for realism: form-driven arguments appeal to the form of inductive inferences, whilst content-driven arguments appeal to their specific content. After regimenting the realism debate in these terms, I will argue that the content-driven arguments are preferable. Along the way I will discuss how my analysis relates to John Norton’s recent, more general (...) thesis that the grounds for licit induction are always material. (shrink)

Practical arguments for actions are arguments which, besides their epistemic function, shall motivate an addressee to execute the justified action. First, a strategy is developed how this motivational and other requirements can be met. Part of this strategy is to identify a thesis for which holds that believing it motivates in the required manner. Second, relying on empirical decision theory, such a thesis is identified. Finally, precise validity criteria for the respective arguments are developed.

This is a short introduction to ontological arguments. It begins with a brief characterization of ontological arguments that proceeds mainly by way of example. The rest of the discussion is given over to consideration of what looks like a very simple ontological argument. This consideration turns up many of the issues that arise when more complex ontological arguments are examined.

On doxastic theories of propositional faith,necessarily,S has faith that p only if S believes that p. On nondoxastic theories of propositional faith, it’s false that,necessarily,S has faith that p only if S believes that p. In this article, I defend three arguments for nondoxastic theories of faith and I respond to published criticisms of them.
