There is abundant evidence of contextual variation in the use of “S knows p.” Contextualist theories explain this variation in terms of semantic hypotheses that refer to standards of justification determined by “practical” features of either the subject’s context (Hawthorne & Stanley) or the ascriber’s context (Lewis, Cohen, & DeRose). There is extensive linguistic counterevidence to both forms. I maintain that the contextual variation of knowledge claims is better explained by common pragmatic factors. I show here that one is variable (...) strictness. “S knows p” is commonly used loosely to implicate “S is close enough to knowing p for contextually indicated purposes.” A pragmatic account may use a range of semantics, even contextualist. I use an invariant semantics on which knowledge requires complete justification. This combination meets the Moorean constraint as well as any linguistic theory should, and meets the intuition constraint much better than contextualism. There is no need for ad hoc error theories. The variation in conditions of assertability and practical rationality is better explained by variably strict constraints. It will follow that “S knows p” is used loosely to implicate that the condition for asserting “p” and using it in practical reasoning are satisfied. (shrink)

In this paper I argue against a criticism by Matthew Weiner to Grice’s thesis that cancellability is a necessary condition for conversational implicature. I argue that the purported counterexamples fail because the supposed failed cancellation in the cases Weiner presents is not meant as a cancellation but as a reinforcement of the implicature. I moreover point out that there are special situations in which the supposed cancellation may really work as a cancellation.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

"The influence of J. L. Austin on contemporary philosophy, which ranks with that of Wittgenstein, was substantial during his lifetime and has grown greatly since his death in 1960, at the height of his powers. His published papers are here gathered together with three pieces that had not been published when this collection first appeared in 1961. This new edition contains two additional papers edited, with the assistance of the original editors, by L. W. Forguson and J. M. E. Moravcsik, (...) that were published till later..." - Back cover.

The influence of J. L. Austin on contemporary philosophy was substantial during his lifetime, and has grown greatly since his death, at the height of his powers, in 1960. Philosophical Papers, first published in 1961, was the first of three volumes of Austin's work to be edited by J. O. Urmson and G. J. Warnock. Together with Sense and Sensibilia and How to do things with Words, it has extended Austin's influence far beyond the circle who knew him or read (...) the handful of papers he published in journals.

It’s a cornerstone of epistemology that knowledge requires truth – that is, that knowledge is factive. Allan Hazlett boldly challenges orthodoxy by arguing thatthe ordinary concept of knowledge is not factive. On this basis Hazlett further argues that epistemologists shouldn’t concern themselves with the ordinary concept of knowledge, or knowledge ascriptions and related linguistic phenomena. I argue that either Hazlett is wrong about the ordinary concept of knowledge, or he’s right in a way that leaves epistemologists to carry on exactly (...) as they have, paying attention to much the same things they always did.

This article provides a semantic analysis of Protagonist Projection, the phenomenon by which things are described from a point of view different from that of the speaker. Against what has been argued by some, the account vindicates the intuitive idea that Protagonist Projection does not give rise to counterexamples to factivity, and similar plausible principles. A pragmatics is sketched that explains the attitude attributions generated by Protagonist Projection. Further, the phenomenon is compared to Free Indirect Discourse, and the proposed account (...) is seen to preserve the relation between them. (shrink)

Contextualism treats ‘knows’ as an indexical that denotes different epistemic properties in different contexts. Contrastivism treats ‘knows’ as denoting a ternary relation with a slot for a contrast proposition. I will argue that contrastivism resolves the main philosophical problems of contextualism, by employing a better linguistic model. Contextualist insights are best understood by contrastivist theory.

Hilary Kornblith argues for a naturalistic approach to investigating knowledge. Knowledge, he explains, is a feature of the natural world, and so should be investigated using scientific methods. He offers an account of knowledge derived from the science of animal behavior, and defends this against its philosophical rivals. This controversial and refreshingly original book offers philosophers a new way to do epistemology.

In Epistemology, Laurence Bonjour introduces the serious philosophy student to the history and concepts of epistemology, while simultaneously challenging them to take an active part in its ongoing debates. The text reflects BonJour's conviction that the place to start any discussion of the theories of knowledge is with the classical problems, beginning with and centered around Descartes.

Introduction -- Part I: The classical problems of epistemology -- Descartes's epistemology -- The concept of knowledge -- The problem of induction -- A priori justification and knowledge -- Immediate experience -- Knowledge of the external world -- Some further epistemological issues : other minds, testimony, and memory -- Part II: Contemporary responses to the cartesian epistemological program -- Introduction to part II -- Foundationalism and coherentism -- Internalism and externalism -- Quine and naturalized epistemology -- Knowledge and skepticism.

In Science and Ethics, Bernard Rollin examines the ideology that denies the relevance of ethics to science. Providing an introduction to basic ethical concepts, he discusses a variety of ethical issues that are relevant to science and how they are ignored, to the detriment of both science and society. These include research on human subjects, animal research, genetic engineering, biotechnology, cloning, xenotransplantation, and stem cell research. Rollin also explores the ideological agnosticism that scientists have displayed regarding subjective experience in humans (...) and animals, and its pernicious effect on pain management. Finally, he articulates the implications of the ideological denial of ethics for the practice of science itself in terms of fraud, plagiarism, and data falsification. In engaging prose and with philosophical sophistication, Rollin cogently argues in favor of making education in ethics part and parcel of scientific training. (shrink)

In a recent paper Savas Tsohatzidis has provided a number of putative counterexamples to the well-attested Kartunnen-Vendler (K-V) thesis that the use of 'tell' with a wh-complement requires that the speaker spoke truthfully. His counterexamples are sentences like: (1) Old John told us who he saw in the fog, but it turned out that he was mistaken. I argue that such examples do not serve to refute the K-V thesis. Rather, they are examples of a more general phenomenon that I (...) label participant projection, which is manifested in sentences like: (2) He gave her a ring studded with diamonds, but they turned out to be glass. Just as the acceptability of (2) does not show that some diamonds are glass, so the acceptability of (1) does not disprove the K-V thesis. (shrink)

I argue for an alternative to invariantist, contextualist, and relativist semantics for ‘know’. This is that our use of ‘know’ is inconsistent; it is governed by several mutually inconsistent inference principles. Yet this inconsistency does not prevent us from assigning an effective content to most individual knowledge ascriptions, and it leads to trouble only in exceptional circumstances. Accordingly, we have no reason to abandon our inconsistent knowledge-talk.
