Belief is considered a kind of performance, which attains one level of success if it is true (or accurate), a second level if competent (or adroit), and a third if true because competent (or apt). Knowledge on one level (the animal level) is apt belief. The epistemic normativity constitutive of such knowledge is thus a kind of performance normativity. A problem is posed for this account by the fact that suspension of belief seems to fall under the same sort of epistemic normativity as does belief itself, yet to suspend is of course precisely not to perform, certainly not with the aim of truth. The paper takes up this problem, and proposes a solution that distinguishes levels of performance norrmativity, including a first order where execution competence is in play, and a second order where the performer must assess the risks attendant on issuing a first-order performance. This imports a level of reflective knowledge that ascends above the animal level.

Testimony is a crucial source of knowledge: we are to a large extent reliant upon what others tell us. It has been the subject of much recent interest in epistemology, and this volume collects twelve original essays on the topic by some of the world's leading philosophers. It will be the starting point for future research in this fertile field. Contributors include Robert Audi, C. A. J. Coady, Elizabeth Fricker, Richard Fumerton, Sanford C. Goldberg, Peter Graham, Jennifer Lackey, Keith Lehrer, Richard Moran, Frederick F. Schmitt, Ernest Sosa, and James Van Cleve.

Davidson’s epistemology, like Kant’s, features a transcendental argument as its centerpiece. Both philosophers reject any priority, whether epistemological or conceptual, of the subjective over the objective, attempting thus to solve the problem of the external world. For Davidson, three varieties of knowledge are coordinate—knowledge of the self, of other minds, and of the external world. None has priority. Despite the epistemologically coordinate status of the mind and the world, however, the content of the mind can be shown to entail how it is out in the world. More exactly, Davidson argues, we could not possibly have the beliefs we have, with their contents, unless the world around us was pretty much the way we take it to be, at least in its general outline. We are thus offered a way to argue, to all appearances a priori, from how it is in our minds to how it is in the world. The argument is a priori at least in being free of premises or assumptions about contingent particularities concerning the world around us or our relation to it. From premises about the contents of our propositional attitudes, the argument wends its way to a conclusion about the general lines of how the world around us is structured and populated. Before presenting his own account, Davidson rejects received views of meaning and knowledge. What follows will combine themes from his critique of alternatives with his more positive account and how it deals with the skeptic.

This chapter takes up, in six sections, issues of realism and of ontological and conceptual relativity. Section 1 briefly lays out the kind of absolutist realism of interest in what follows. Section 2 considers arguments against ordinary commonsense entities such as bodies, and for the view that subjects enjoy a superior ontological position. No such argument is found persuasive. I find no good argument against ordinary bodies or other common-sense entities, nor any good argument that subjects enjoy any ontological superiority. Section 3 lays out three options in ontology, opts for a kind of conceptual relativism, and takes up three problems for the proposed view. Section 4 then offers a compromise position based on a kind of existential relativity meant to accommodate our most settled beliefs about what there is, while retaining a fundamentally realist and objectivist ontology. The main argument of that section relies on a distinction between semantical relativity and ontological relativity. Section 5 defends my use of the semantical-ontological distinction against objections to it in the recent literature. Section 6, in conclusion, takes up arguments for the view that, as subjects of consciousness and thought, we must after all occupy a special ontological position in objective reality, one whose status remains mysterious

In what way is knowledge better than merely true belief? That is a problem posed in Plato’s Meno. A belief that falls short of knowledge seems thereby inferior. It is better to know than to get it wrong, of course, and also better than to get it right by luck rather than competence. But how can that be so, if a true belief will provide the same benefits? In order to get to Larissa you do not need to know the way. A true belief will get you there just as well. Is it really always better to know the answer to a question than to get it right by luck? In part i we ponder: Is knowledge always better at least in epistemic respects? The affirmative answer is subject to doubts deriving from a conception of belief as sufficient confidence, but is defensible against such doubts. In our search for the special value of knowledge, we then explore in part ii the relation between knowledge and proper action. Part iii goes on to consider how the value of knowledge intuition acquires further interest through its equivalence with the view of knowledge as a norm of assertion. Finally, part iv steps back to examine what we might mean in saying that to know is always, necessarily better than to get it right by luck while really in ignorance. In order to defend our value-of-knowledge intuition we need first to understand it more clearly. Part iv offers an explanation.

The received definition of knowledge (as true, evident belief) has recently been questioned by Edmund Gettier with an example whose principle is as follows. A proposition, p, is both evident to and accepted by someone S, who sees that its truth entails (would entail) (that either p is true or q is true). This last is thereby made evident to him, and he accepts it, but it happens to be true only because q is true, since p is in fact false. Hence, inasmuch as he has no evidence for the proposition q, S can hardly be said to know (that either p is true or q is true). Here then is a formula for true, evident beliefs that are not cases of knowledge. I discuss the possibility of adding a fourth condition to this triad.
