This issue of Episteme is devoted to the topic of epistemic relativism. It includes a symposium on Paul Boghossian's treatment of epistemic relativism in chapters 5 through 7 of his new book, Fear of Knowledge (2006). The symposium centers on Boghossian's argument against epistemic relativism in chapter 6 of that book. In their contributions to the symposium, Gideon Rosen and Ram Neta offer criticisms of Boghossian's argument, and Neta argues for a version of epistemic relativism. In addition to the symposium, Jonathan Weinberg, Michael Williams, and Roger White supply stand-alone articles on related topics. The purpose of this introduction is to situate epistemic relativism in the constellation of relativist views, to distinguish several forms of epistemic relativism, and to remark briefly on how the versions of relativism discussed in the articles in this issue fit these forms of relativism.

According to one sort of epistemic relativist, normative epistemic claims (e.g., evidence E justifies hypothesis H) are never true or false simpliciter, but only relative to one or another epistemic system. In chapter 6 of Fear of Knowledge, Paul Boghossian objects to this view on the ground that its central notions cannot be explained, and that it cannot account for the normativity of epistemic discourse. This paper explores how the dogged relativist might respond.

In Fear of Knowledge, Paul Boghossian argues against various forms of epistemic relativism. In this paper, I criticize Boghossian’s arguments against a particular variety of relativism. I then argue in favor of a thesis that is very similar to this variety of relativism.

Unlike the relativistic theses drawn from physics, normative relativisms involve relativization not to frames of reference but to something like our standards, standards that we have to be able to think of ourselves as endorsing or accepting. Thus, moral facts are to be relativized to moral standards and epistemic facts to epistemic standards. But a moral standard in this sense would appear to be just a general moral proposition and an epistemic standard just a general epistemic proposition. Pulling off either relativism, then, requires not just relativizing the facts in the domain in question to the relevant standards; it requires taking a non-absolutist view of the standards themselves. Otherwise a commitment to absolute truths in the domain in question will show up in one’s attitude towards the standards themselves. But it is very hard to see how to take a genuinely non-absolutist attitude towards the standards themselves. That, in essence, is the difficulty for a relativistic view of a normative domain that I tried to develop in Chapter 6 of Fear of Knowledge. In their commentaries, Gideon Rosen and Ram Neta come up with ingenious ways of attempting to circumvent that difficulty. In my reply, I try to explain why I don’t believe they succeed.

Although radical forms of relativism are perhaps beyond the epistemological pale, I argue here that a more moderate form may be plausible, and articulate the conditions under which moderate epistemic relativism could well serve our epistemic goals. In particular, as a result of our limitations as human cognizers, we find ourselves needing to investigate the dappled and difficult world by means of competing communities of highly specialized researchers. We would do well, I argue, to admit of the existence of unresolvable disputes between such communities, but only so long as there is a sufficient amount of fruitful exchange between them as well. I close with some speculation about when it is or is not legitimate to make an “appeal to discipline”: responding to another’s argument by saying something like, “we should do it this way, because we are philosophers (/linguists/psychologists/…), and that’s just what we do”.

This article distinguishes Wittgensteinian contextualism from epistemic relativism. The latter involves the view that a belief’s status as justified depends on the believer’s epistemic system, as well as the view that no system is superior to another. It emerges from the thought that we must rely, circularly, on our epistemic system to determine whether any belief is justified. Contextualism, by contrast, emerges from the thought that we need not answer a skeptical challenge to a belief unless there is good reason to doubt the belief; so we need not rely on our epistemic system to determine whether a belief is justified. Accordingly contextualism is not committed to the view that a belief’s status depends on the believer’s epistemic system, nor to the view that no system is superior to another. The contextualist is not committed to epistemic relativism.

Epistemic subjectivism, as I am using the term, is a view in the same spirit as relativism, rooted in skepticism about the objectivity or universality of epistemic norms. I explore some ways that we might motivate subjectivism drawing from some common themes in analytic epistemology. Without diagnosing where the arguments go wrong, I argue that the resulting position is untenable.
