This paper deals with the truth-Conditions and the logic for vague languages. The use of supervaluations and of classical logic is defended; and other approaches are criticized. The truth-Conditions are extended to a language that contains a definitely-Operator and that is subject to higher order vagueness.

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition.Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the (...) criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge.Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists. (shrink)

Once upon a time it was assumed that speaking literally and directly is the norm and that speaking nonliterally or indirectly is the exception. The assumption was that normally what a speaker means can be read off of the meaning of the sentence he utters, and that departures from this, if not uncommon, are at least easily distinguished from normal utterances and explainable along Gricean lines. The departures were thought to be limited to obvious cases like figurative speech and conversational (...) implicature. However, people have come to appreciate that the meaning of a typical sentence, at least one we are at all likely to use, is impoverished, at least relative to what we are likely to mean in uttering it. In other words, what a speaker normally means in uttering a sentence, even without speaking figuratively or obliquely, is an enriched version of what could be predicted from the meaning of the sentence alone. This can be because the sentence expresses a “minimal” (or “skeletal”) proposition or even because it fails to express a complete proposition at all.1 Indeed, it is now a platitude that linguistic meaning generally underdetermines speaker meaning. That is, generally what a speaker means in uttering a sentence, even if the sentence is devoid of ambiguity, vagueness, or indexicality, goes beyond what the sentence means. The question is what to make of this Contextualist Platitude, as I’ll call it. It may be a truism, but does it require a radical revision of the older conception of the relation between what sentences mean and what speakers mean in uttering them? Does it lead to a major modification, or perhaps even outright rejection, of the semantic-pragmatic distinction? I think.. (shrink)

This volume succeeds the same authors' well-known An Introduction to Modal Logic and A Companion to Modal Logic. We designate the three books and their authors NIML, IML, CML and H&C respectively. Sadly, George Hughes died partway through the writing of NIML.

This long-awaited book replaces Hughes and Cresswell's two classic studies of modal logic: _An Introduction to Modal Logic_ and _A Companion to Modal Logic_. _A New Introduction to Modal Logic_ is an entirely new work, completely re-written by the authors. They have incorporated all the new developments that have taken place since 1968 in both modal propositional logic and modal predicate logic, without sacrificing tha clarity of exposition and approachability that were essential features of their earlier works. The book takes (...) readers from the most basic systems of modal propositional logic right up to systems of modal predicate with identity. It covers both technical developments such as completeness and incompleteness, and finite and infinite models, and their philosophical applications, especially in the area of modal predicate logic.

Contextualism in epistemology is the doctrine that the proposition expressed by a knowledge attribution relative to a context is determined in part by the standards of justification salient in that context. The (non-skeptical) contextualist allows that in some context c, a speaker may truly attribute knowledge at a time of a proposition p to Hannah, despite her possession of only weak inductive evidence for the truth of that proposition. Relative to another context, someone may make the very same knowledge attribution (...) to Hannah, yet be speaking falsely, because the epistemic standards in that context are higher. The reason this is possible, according to the contextualist, is that the two knowledge attributions express different propositions. (shrink)
