A major purpose of this book is to make the post-Hamblin work on fallacies available to a wider audience in a single, convenient volume.

Following David Hitchcock and Stephen Toulmin, this paper takes warrants to be material inference rules. It offers an account of the form such rules should take that is designed (a) to implement the idea that an argument/inference is valid only if it is entitlement preserving and (b) to support a qualitative version of evidence proportionalism. It attempts to capture what gives warrants their normative force by elaborating a concept of reliability tailored to its account of the form such rules should (...) take. (shrink)

Argumentation involves offering and/or exchanging reasons – either reasons for adopting various attitudes towards specific propositional contents or else reasons for acting in various ways. This paper develops the idea that the force of reasons is through and through a normative force because what good reasons accomplish is precisely to give one a certain sort of entitlement to do what they are reasons for. The paper attempts to shed light on what it is to have a reason, how the sort (...) of entitlement arising from reasons differs from other species of entitlement and how the norms by which such entitlement is assessed obtain their status as norms.

This paper challenges the view that arguments are (by definition, as it were) attempts to persuade or convince an audience to accept (or reject) a point of view by presenting reasons for (or against) that point of view. I maintain, first, that an arguer need not intend any effect beyond that of making it manifest to readers or hearers that there is a reason for doing some particular thing (e.g., for believing a certain proposition, or alternatively for rejecting it), and (...) second that when an arguer is in fact trying to induce an effect above and beyond rendering a reason manifest, the effect intended—the use to which his or her argument is put—need not be that hearers do what the stated reasons are reasons for doing. Where the actual or intended effect of making a reason R for doing X manifest is something other than doing X, I call it an oblique—as opposed to a direct—effect of making that reason manifest. The core of the paper presents an overview or map of the main categories of effect which arguments can have, and the main sub-types within each category, calling attention to the points at which such effects can be indirect or oblique effects. The purpose of that typology is to make it clear (i) how oblique effects can come about and (ii) how important a role they can play in the conduct of argumentation. (shrink)

ABSTRACT: This paper highlights the difference between Lilian Bermejo-Luque’s account of warrants with the quite different accounts of warrants offered by Toulmin, Hitchcock, and myself, and lays out some of the reasons why I think a “Toulminesque” account of warrants captures crucial aspects of arguing more adequately than her account does.RESUMEN: Este artículo subraya la diferencia entre el análisis de los garantes que nos propone Lilian Bermejo-Luque con los de Toulmin, Hitchcok y el mío propio. Presento algunas razones por las (...) que pienso que un análisis toulminiano de los garantes capta mejor que el suyo algunos aspectos cruciales de la argumentación. (shrink)

This paper attempts two things: to give the reader a very general idea of the main outlines of what Govier has to say both about social and political trust and about trust in personal relationships, and to present in slightly more detail what she says about the role of trust in acquiring belief and/or knowledge from testimony and about the reasons for trusting such testimony.

In section I, I argue that the principal reason why inconsistency is a fault is that it involves having at least one false belief. In section 2, I argue that inconsistency need not be a serious epistemic fault. The argument in section 2 is based on the notion that what matters epistemically is always in the final analysis an item's effect on attaining the goal of truth. In section 3 I describe two cases in which it is best from an (...) epistemic point of view to knowingly retain inconsistent beliefs. In section 4 my goal is to put into perspective the charge that relativism ought to be rejected because it involves one in inconsistency. (shrink)
