William James once said that truth is “the good in the way of belief.” This has the ring of, well, truth. While it may appear as if James’ claim is straightforwardly true, I think that there are at least three different dimensions along which truth can be normatively related to belief. In this paper, I explore these different dimensions of truth’s value, considering both how they differ and how they relate. As we will see, our understanding of these different dimensions of truth’s value can impact our understanding of its nature. I argue that a fuller understanding of the connections between truth’s normative dimensions pushes us in a decidedly pragmatist and pluralist direction—something of which I believe James would approve.

For most people, the internet is now the most dominant source of socially useful knowledge. Its widespread use has made knowledge more accessible, more widely distributed, and more commonly produced. But the internet is also widely seen—and not just by philosophers—as raising a number of distinct epistemological problems. Some of those problems concern the metaphysics of knowledge—the extent to which knowledge via the internet is understood as outsourced, or even extended, knowledge. Others concern the type of knowledge the internet can give us—whether, for example, the knowledge we gain by using our digital devices is a kind of testimonial knowledge. In this chapter, we will focus on a third issue: how our uses of the internet to gain information affect our epistemic agency—or our capacity to take responsibility for our own epistemically relevant mental states and our wider contributions to our epistemic environment. In the early days of digital technology, the internet was generally seen as increasing our epistemic agency for the simple reason that it made information (and presumably knowledge) more accessible and widespread. But in recent years, such optimism has been tempered due to the rise of fake news, massive amounts of misinformation online, and the average consumer’s seeming credulity with regard to what they read on social media. The chapter will outline these objections and critically examine them, arguing that both our epistemic agency and our ability to responsibly exercise such agency can be undermined by some uses of the internet, even as those same uses increase agency in other ways.

In a recent New Yorker cartoon, a man is fixing a sink. His partner, standing nearby skeptically asks, “Do you really know what you are doing, or do you only google-​know?” This cartoon perfectly captures the mixed relationship we have with googling, or knowing via digital interface, particularly via search engines. On the one hand, googling is now the dominant source of socially useful knowledge. The use of search engines for this purpose is almost completely integrated into many of our lives. On the other, the point the cartoon is making resonates with nearly all of us: users often recognize that there are risks and trade-​offs associated with gaining certain kinds of information via online search. These facts about googling make it particularly interesting to the applied epistemologist. Our practices involving search engines not only have a distinctive character, that character puts some traditional epistemic questions in a new light. This chapter will examine two of those questions. The first concerns the extent to which googling raises problems similar to familiar quandaries surrounding testimonial knowledge. The second –​and more radical –​concerns whether googling is a type of distributed or extended knowledge.

Are most people sincere when they share misinformation and conspiracies online? This question, while natural and important, is difficult to answer for obvious reasons. But it also applies poorly to one of the main vehicles for misinformation—memes. And it can be ambiguous; as a result, we should be mindful of two distinctions. First, a distinction between belief and a related propositional attitude, commitment. And second, the distinction between the propositional content of an attitude and what I will call its political meaning. I will suggest that these distinctions not only can help us understand how we communicate online, but they also suggest a lesson about what we should be focusing on when fighting misinformation.

In this paper we discuss three different kinds of disagreement that have been, or could reasonably be, characterized as deep disagreements. Principle level disagreements are disagreements over the truth of epistemic principles. Sub-principle level deep disagreements are disagreements over how to assign content to schematic norms. Finally, framework-level disagreements are holistic disagreements over meaning not truth, that is over how to understand networks of epistemic concepts and the beliefs those concepts compose. Within the context of each of these kinds of disagreement it is not possible for the parties to the dispute to rationally persuade one another through only offering epistemic reasons for their conflicting points of view. However, in spite of the inability to rationally persuade, we explore how it may nevertheless be possible to rationally navigate each of these varieties of deep disagreement.

In this essay, I present a new argument for the impossibility of defining truth by specifying the underlying structural property all and only true propositions have in common The set of considerations I use to support this claim take as that inspiration Alston's recent argument that it is impossible to define truth epistemically—in terms of justification or warrant According to what Alston calls the “intensional argument”, epistemic definitions are inconsistent with the T schema or the principle that it is true that p if, and only if, p. Since the T-schema has great intuitive appeal, this is a powerful indictment of epistemic theories. But the basic argument that Alston employs, and the constellation of considerations which prosecute that argument, work against a much broader range of views than he considers While this implies that a traditional conceptual analysts of truth may be impossible, it opens the door to a pluralist approach to truth.

Democracies, Dewey and others have argued, are ideally spaces of reasons – they allow for an exchange of reasons both practical and epistemic by those willing to engage in that discourse. That requires that citizens have convictions they believe in, but it also requires that they be willing to listen to each other. This paper examines how a particular psychological attitude, “epistemic arrogance,” can undermine the achievement of these goals. The paper presents an analysis of this attitude and then examines four arguments for how its adoption – especially by the powerful – undermines the ideal of democracy as a space of reasons.

Reasons, Wittgenstein warned, come to an end; we hit bedrock; the spade is turned. Long philosophical tradition, not to mention common sense, agrees. You can’t justify everything. In this paper, I examine a case where it is not only especially compelling that reasons run out—it is especially troubling. The case is when there is disagreement over explicitly epistemic first principles. Epistemic first principles are principles that announce that basic methods for acquiring beliefs are reliable. Where we disagree over such principles, we face the alarming prospect of being unable to defend them without relying on the very methods whose reliability is in question. I then explore, however briefly, what options remain in such situations for still engaging in what we might call rational persuasion. I suggest our prospects depend on whether we can make sense of giving objective practical reasons for our epistemic first principles.

Although Alston believed epistemically circular arguments were able to justify their conclusions, he was also disquieted by them. We will argue that Alston was right to be disquieted. We explain Alston’s view of epistemic circularity, the considerations that led him to accept it, and the purposes he thought epistemically circular arguments could serve. We then build on some of Alston’s remarks and introduce further limits to the usefulness of such arguments and introduce a new problem that stems from those limits. The upshot is that adopting Alston’s view that epistemically circular arguments can be used to justify their conclusions is more costly than even he thought.

In Truth as One and Many, Michael Lynch offers a new theory of truth. There are two kinds of theory of truth in the literature. On the one hand, we have logical theories, which seek to construct formal systems that are consistent, while also containing a predicate which have as many as possible of the properties which we ordinarily take the English predicate ‘is true’ to have; salient examples include Tarski’s and Kripke’s theories of truth. On the other hand, we have metaphysical theories, which seek to give a non-formal account of the nature of truth – of what truth consists in, of what it means to say that something is true; salient examples include correspondence, coherence and deflationary theories of truth. Lynch’s theory – functionalism about truth – is of the second sort.The theory takes its start from a number of principles which Lynch classifies as truisms about truth:Objectivity: The belief that p is true if, and only if, with respect to the belief that p, things are as they are believed to be.Norm of Belief: It is prima facie correct to believe that p if and only if the proposition that p is true.End of Inquiry: Other things being equal, true beliefs are a worthy goal of inquiry.Lynch argues that other familiar principles can be derived from these: for example, Objectivity together with some auxiliary principles and definitions yields versions of the T-schema, and of the principle that beliefs can be true without being warranted and vice versa. These principles are supposed to give the nominal essence of truth – to constitute our folk theory of truth. Lynch …
