Subject sensitive invariantism is the view that whether a subject knows depends on what is at stake for that subject: the truth-value of a knowledge-attribution is sensitive to the subject's practical interests. I argue that subject sensitive invariantism cannot accept a very plausible principle for memory to transmit knowledge. I argue, furthermore, that semantic contextualism and contrastivism can accept this plausible principle for memory to transmit knowledge. I conclude that semantic contextualism and contrastivism are in a dialectical position better than (...) subject sensitive invariantism is. (shrink)

This paper defends a purely semantic notionof what is said against various recent objections. Theobjections each cite some sort of linguistic,psychological, or epistemological fact that issupposed to show that on any viable notion of what aspeaker says in uttering a sentence, there ispragmatic intrusion into what is said. Relying on amodified version of Grice's notion, on which what issaid must be a projection of the syntax of the utteredsentence, I argue that a purely semantic notion isneeded to account for the (...) linguistically determinedinput to the hearer's inference to what, if anything,the speaker intends to be conveying in uttering thesentence.

The claim of this paper is that the everyday functions of knowledge make most sense if we see knowledge as contrastive. That is, we can best understand how the concept does what it does by thinking in terms of a relation “a knows that p rather than q.” There is always a contrast with an alternative. Contrastive interpretations of knowledge, and objections to them, have become fairly common in recent philosophy. The version defended here is fairly mild in that there (...) is no suggestion that we cannot think in terms of a simpler not explicitly contrastive relation “a knows that p.” Some, for instance Schaffer (2005) and Karjalainen and Morton (2003), have hinted that this stronger possibility may be right. But all that I am arguing now is that facts that are easily expressed in contrastive terms are vital to understanding why we need the concept of knowledge. In a piece that is in some ways a companion to this one ("Contrastivism" in Duncan Pritchard and Sven Bernecker, eds. The Routledge Companion to Epistemology. Routledge 2010, 513-522), I give a general survey of theories of contrastive knowledge and the differences between them. (shrink)

How should one understand knowledge-wh ascriptions? That is, how should one understand claims such as ‘‘I know where the car is parked,’’ which feature an interrogative complement? The received view is that knowledge-wh reduces to knowledge that p, where p happens to be the answer to the question Q denoted by the wh-clause. I will argue that knowledge-wh includes the question—to know-wh is to know that p, as the answer to Q. I will then argue that knowledge-that includes a contextually (...) implicit question. I will conclude that knowledge is a question-relative state. Knowing is knowing the answer, and whether one knows the answer depends (in part) on the question. (shrink)

Knowledge ascriptions are contrast-sensitive. One natural explanation for this is that the knowledge relation is contrastive ( s knows that p rather than q ). But can the binary view of knowledge ( s knows that p ) explain contrast-sensitivity? I review some of the linguistic data supporting contrast-sensitivity, and critique the three main binary explanations for contrast-sensitivity. I conclude that the contrast-sensitivity of knowledge ascriptions shows that knowledge is a contrastive relation.

This essay invokes a technical framework of contrast classes within which Pyrrhonians can accept knowledge claims that are relativized to specific contrast classes, but avoid all unrelativized knowledge claims and all presuppositions about which contrast classes are really relevant. Pyrrhonians can then assert part of the content of everyday knowledge claims without privileging the everyday perspective or any other perspective. This framework provides a precise way to understand the central claims of neo-Pyrrhonism while avoiding most, if not all, of the (...) problems and objections raised by its critics. (shrink)

Does what you know depend on what is at stake for you? That is, is the knowledge relation sensitive to the subject’s practical interests? Subject sensitive invariantists (Fantl and McGrath, 2002; Hawthorne, 2004, ch. 4; Stanley, forthcoming) say that the answer is yes. They claim to capture the contextualist data without the shifty semantics. I will argue that the answer is no. The knowledge relation is sensitive to what is in question for the attributor, rather than what is at stake (...) for the subject. There is no substitute for the contextualist semantics. (shrink)

How must knowledge be formed, if made in the image of assertion? That is, given that knowledge plays the normative role of governing what one may assert, what can be inferred about the structure of the knowledge relation from this role? I will argue that what one may assert is sensitive to the question under discussion, and conclude that what one knows must be relative to a question. In short, knowledge in the image of assertion is question-relative knowledge.

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.

We describe the three place relation of contrastive knowledge, which holds between a person, a target proposition, and a contrasting proposition. The person knows that p rather than that q. We argue for three claims about this relation. (a) Many common sense and philosophical ascriptions of knowledge can be understood in terms of it. (b) Its application is subject to fewer complications than non-contrastive knowledge is. (c) It applies over a wide range of human and nonhuman cases.

Radical skepticism, the view that no human being has any contingent knowledge of any external world there may be, has few adherents these days. But many who reject it concede that such skeptical arguments as SA require some sort of response, since they are obviously valid and their premises are, at the very least, highly plausible.

Throughout the history of philosophy, skepticism has posed one of the central challenges of epistemology. Opponents of skepticism--including externalists, contextualists, foundationalists, and coherentists--have focussed largely on one particular variety of skepticism, often called Cartesian or Academic skepticism, which makes the radical claim that nobody can know anything. However, this version of skepticism is something of a straw man, since virtually no philosopher endorses this radical skeptical claim. The only skeptical view that has been truly held--by Sextus, Montaigne, Hume, Wittgenstein, and, (...) most recently, Robert Fogelin--has been Pyrrohnian skepticism. Pyrrhonian skeptics do not assert Cartesian skepticism, but neither do they deny it. The Pyrrhonian skeptics' doubts run so deep that they suspend belief even about Cartesian skepticism and its denial. Nonetheless, some Pyrrhonians argue that they can still hold "common beliefs of everyday life" and can even claim to know some truths in an everyday way. This edited volume presents previously unpublished articles on this subject by a strikingly impressive group of philosophers, who engage with both historical and contemporary versions of Pyrrhonian skepticism. Among them are Gisela Striker, Janet Broughton, Don Garrett, Ken Winkler, Hans Sluga, Ernest Sosa, Michael Williams, Barry Stroud, Robert Fogelin, and Roy Sorensen. This volume is thematically unified and will interest a broad spectrum of scholars in epistemology and the history of philosophy. (shrink)

All contentious moral issues--from gay marriage to abortion and affirmative action--raise difficult questions about the justification of moral beliefs. How can we be justified in holding on to our own moral beliefs while recognizing that other intelligent people feel quite differently and that many moral beliefs are distorted by self-interest and by corrupt cultures? Even when almost everyone agrees--e.g. that experimental surgery without consent is immoral--can we know that such beliefs are true? If so, how? These profound questions lead to (...) fundamental issues about the nature of morality, language, metaphysics, justification, and knowledge. They also have tremendous practical importance in handling controversial moral questions in health care ethics, politics, law, and education. Sinnott-Armstrong here provides an extensive overview of these difficult subjects, looking at a wide variety of questions, including: Are any moral beliefs true? Are any justified? What is justified belief? The second half of the book explores various moral theories that have grappled with these issues, such as naturalism, normativism, intuitionism, and coherentism, all of which are attempts to answer moral skepticism. Sinnott-Armstrong argues that all these approaches fail to rule out moral nihilism--the view that nothing is really morally wrong or right, bad or good. Then he develops his own novel theory,--"moderate Pyrrhonian moral skepticism"--which concludes that some moral beliefs can be justified out of a modest contrast class but no moral beliefs can be justified out of an extreme contrast class. While explaining this original position and criticizing alternatives, Sinnott-Armstrong provides a wide-ranging survey of the epistemology of moral beliefs. (shrink)
