According to the standard conception of the “value problem” in epistemology, the problem originates with a compelling pretheoretical intuition to the effect that knowledge is more valuable than true belief.[i] Call this the “guiding intuition.” The guiding intuition is thought to motivate a constraint on an analysis of knowledge such that any plausible analysis must entail that knowledge is more valuable than true belief. A problem emerges in light of two additional considerations. The first is that knowledge is roughly justified or warranted true belief.[ii] The second is that given certain popular accounts of knowledge, the value of justification or warrant is apparently derivative from and reducible to the value of true belief.[iii] But if knowledge is justified true belief, then these accounts apparently fail to entail that knowledge has value over and above the value of true belief and so fail to satisfy the relevant constraint. Defenders of these theories of knowledge have generally responded by attempting to show that the value of justification as they conceive of it is not entirely derivative from the value of true belief and hence that their theories do satisfy the relevant constraint and so are able to overcome the value problem.[iv].

Adequate epistemic justification is best conceived as the appearance, over time, of knowledge to the subject. ‘Appearance’ is intended literally, not as a synonym for belief. It is argued through consideration of examples that this account gets the extension of ‘adequately justified belief’ at least roughly correct. A more theoretical reason is then offered to regard justification as the appearance of knowledge: If we have a knowledge norm for assertion, we do our best to comply with this norm when we express as assertions only beliefs that appear to us to be knowledge. If we are doing our best, there is little point in further sanctions. So a norm of knowledge for assertion would lead to a secondary norm of justified belief as the appearance of knowledge, marking a point at which our assertions may be corrected but should not be blamed.

The value problem in epistemology is rooted in a commonsense intuition to the effect that knowledge is more valuable than true belief. Call this the “guiding intuition.” The guiding intuition generates a problem in light of two additional considerations. The first is that knowledge is (roughly) justified or warranted true belief.[1] The second is that on certain popular accounts of justification or warrant (e.g. reliabilism), its value is apparently instrumental to and hence derivative from the value of true belief.[2] But if knowledge is justified true belief and the value of justification is derivative from that of true belief, how is it that knowledge is more valuable than true belief?

In Knowledge and Belief, Frederick Schmitt explores the nature and value of knowledge and justified belief through an examination of the dispute between epistemological internalism and externalism. Knowledge and justified belief are naturally viewed as belief of a sort likely to be true--an externalist view. It is also intuitive, however, to view them as an internal matter; justification must be accessible to the subject or constituted by the subject's epistemic perspective. The author argues against the view that internalism is the historically dominant epistemology by examining closely the epistemological principles that underlie the treatment of skepticism in Plato, the Academic and Pyrrhonian skeptics, Descartes and Hume. Schmitt develops a sustained, detailed argument against many forms of internalism in favor of a reliabilist/externalist epistemology. His version of reliabilism, though strictly externalist, accommodates and explains the most durable intuitions alleged to support internalism. Knowledge and Belief assumes no knowledge of epistemology or its history. Readers of philosophy will find this an excellent introduction to ancient and modern epistemology; this systematic study of the internalist and externalist debate is the first of its kind.

Crispin Sartwell ingeniously defends the provocative thesis that mere true belief suffices for knowledge. In doing so, he challenges one of the most deeply entrenched epistemological tenets, namely that knowledge must be more than mere true belief. Particularly interesting is the way he defends his thesis by appealing to considerations adduced by such prominent epistemologists as William Alston, Laurence BonJour, Alvin Goldman and Paul Moser, each of whom denies that knowledge is merely true belief. In this paper, I argue that the case Sartwell presents for his thesis fails. However, by examining why it fails, we may derive at least four important epistemological lessons: (1) being justified does not entail being able to give a justification; (2) we should distinguish between epistemic justification conceived of as intrinsically conducive to truth and conceived of as extrinsically conducive to truth; (3) we should distinguish between epistemic justification conceived of as an essential criterion of knowledge and conceived of as an accidental criterion of knowledge; and (4) epistemologists need to specify how the telos of inquiry involves more than the acquisition of (merely) true beliefs.

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

Where is the justificatory boundary between a true belief’s not being knowledge and its being knowledge? Even if we put to one side the Gettier problem, this remains a fundamental epistemological question, concerning as it does the matter of whether we can provide some significant defence of the usual epistemological assumption that a belief is knowledge only if it is well justified. But can that question be answered non-arbitrarily? BonJour believes that it cannot be – and that epistemology should therefore abandon the concept of knowledge. More optimistically, this paper does attempt to answer that question, by applying – and thereby refining – a non-absolutist theory of knowledge.
