This chapter formulates a rational uniqueness principle holding that those who are epistemic peers on a proposition, in that they know that they share all rational considerations concerning the truth of the proposition, cannot be justified in having different attitudes toward it. It then argues against the principle, primarily on the grounds that such peers may rationally regard themselves as differing in their basis for rational belief, or their evidence, on the topic. The rationality of their differing perspectives can justify having different attitudes toward the disputed proposition.

In “Why the generality problem is everybody’s problem,” Michael Bishop argues that every theory of justification needs a solution to the generality problem. He contends that a solution is needed in order for any theory to be used in giving an acceptable account of the justificatory status of beliefs in certain examples. In response, first I will describe the generality problem that is specific to process reliabilism and two other sorts of problems that are essentially the same. Then I will argue that the examples that Bishop presents pose no such problem for some theories. I will illustrate the exempt theories by describing how an evidentialist view can account for the justification in the examples without having any similar problem. It will be clear that other views about justification are likewise unaffected by anything like the generality problem.

A belief is debased when believing is given a basis that is not proper for knowledge, such as wishful thinking or superstition. The possibility of a debasing demon is the possibility of a maximally powerful agent who aims to prevent knowledge by debasing beliefs. Jonathan Schaffer contends that the debasing demon is a threat to all knowledge. Schaffer does not assess the strength of the skeptical challenge from debasing. It is argued here that debasing does not strengthen any case for skepticism. A debasing demon is possible. We should acknowledge that our beliefs could have been debased, and that this could have been done in an introspectively undetectable way. But acknowledging this leaves us in a position to know that our apparent knowledge is genuine. It does not enhance any reason to think that we lack knowledge.
