I present and defend a unified, non-reductive analysis of the a priori and a posteriori. It is a mistake to remove all epistemic conditions from the analysis of the a priori (as, for example, Alvin Goldman has recently suggested doing). We can keep epistemic conditions (like unrevisability) in the analysis as long as we insist that a priori and a posteriori justification admit of degrees. I recommend making the degree to which a belief’s justification is a priori or a posteriori solely dependent on the revisability relations that obtain among the faculties that deliver the belief and all other faculties

In Sect. 1 of this chapter, Matthew McGrath examines Sosa's work on the nature of truth. Sosa's chief purpose is to determine what sort of theory of truth is appropriate for truth-centered epistemology -- an epistemology that takes truth to be the goal of inquiry and which explains key epistemic notions in terms of truth. While Sosa refutes arguments from Putnam and Davidson against the correspondence theory, he is hesitant to endorse it because he doubts we have a clear enough grasp of what correspondence amounts to and what the correspondents are. A truth-centered epistemologist, however, is free to work with minimalism about truth and Moorean primitivism. Part of Sosa's case for primitivism, and against minimalism, involves a comparison with Moore's account of goodness. Here McGrath notes an important dissimilarity between the two (i.e., susceptibility to open-question arguments) and suggests that this may be reason to prefer minimalism to primitivism. In Sect. 2, Jeremy Fantl discusses Sosa's work on the role of truth in epistemology. Sosa seems to be motivated by a dilemma facing any account of that role on which true belief is the sole fundamental epistemic value. On the one hand, we want an account of the role of truth in epistemology to explain why we epistemically evaluate beliefs and guide our intellectual lives in the way we do. On the other hand, it should not come out that we have any sort of epistemic obligation to form beliefs about completely boring or trivial matters (e.g., about the first phone number listed on page 356 of the phone book). Sosa's attempt to resolve the dilemma is to, first of all, adopt something like a pluralism about epistemic value and, second of all, move the primary locus of epistemic evaluation from beliefs to faculties. The second part of this chapter investigates the intricacies of these maneuvers.

I argue in favor of the possibility of real a priori justification. Some writers have claimed that, to adequately defend against the naturalist, we should grant that a priori justification can be defeated by further experiential evidence. Such writers generally view a priori faculties as on a par with empirical faculties but with different proper objects. While perceptual objects are the contingently existing things with which we are in causal contact, a priori objects are either necessarily true propositions or necessarily existing abstract objects with which we are not in causal contact. ;Though I admit that there is a weak sense of a priori justification according to which an a priori justified belief can become irrational in the face of experiential evidence, I argue that genuine a priori justification cannot be overridden by further experiential considerations . Allowing that a priori justification admits of degrees, we can be more or less a priori justified in a belief, depending on the extent to which that belief is revisable in the face of experiential evidence. In this way, I argue that the naturalist, in saying that a priori justification can always be defeated by experiential evidence, does not impugn the possibility that some beliefs can have a greater degree of a priori justification than others . I further argue that experiential beliefs derive much of their justification from a large background network of beliefs with a high degree of a priori justification. Some inference rules, I argue, in licensing the revision of empirical beliefs, must be unrevisable in their own right. Thus, if the naturalist is right, and a priori justification does require mysterious, occult processes, then so does experiential justification. If mysterious, occult processes are to be avoided at all costs, naturalism commits us to a rather extreme form of philosophical skepticism

This paper brings together two recent developments in the theory of epistemic justification: practical conditions on justification, and infinitism (the view thatjustification is a matter of having an infinite series of non-repeating reasons). Pragmatic principles can be used to argue that, if we’re looking for an ‘objective’ theory of the structure of justification – a theory that applies to all subjects independently of their practical context – infinitism stands the only chance at being the correct theory.

Evidentialism is the thesis that epistemic justification for belief supervenes on evidential support. However, we claim there are cases in which, even though two subjects have the same evidential support for a proposition, only one of them is justified. What make the difference are pragmatic factors, factors having to do with our cares and concerns. Our argument against evidentialism is not based on intuitions about particular cases. Rather, we aim to provide a theoretical basis for rejecting evidentialism by defending a “pragmatic” necessary condition on epistemic justification. We argue for the following necessary condition for justification: S is justified in believing that p only if S is rational to prefer (and, hence, act) as if p. In light of this necessary condition, the price of evidentialism is skepticism, or something close to it.

I argue, contra Dreier, Blackburn, and others, that there are no morally neutral metaethical positions. Every metaethical position commits you to the denial of some moral statement. So, for example, the metaethical position that there are no moral properties commits you to the denial of the moral conjunction of 1) it is right to interfere violently when someone is wrongly causing massive suffering and 2) it is wrong to interfere violently when only non-moral properties are at stake. The argument generalizes to all metaethical positions

Dogmatism is the view that it is often legitimate to flatly dismiss counterarguments to a belief: your belief can count as knowledge even if you can’t figure out what’s wrong with the counterargument. Hume defended a version of dogmatism restricted to testimony in favor of miracles. Moore defended a dogmatism restricted to arguments for skepticism. In this paper it is argued that Hume’s and Moore’s dogmatisms should be generalized to all controversial matters. Dogmatism about controversial matters is true if you can have knowledge about controversial matters. That’s because, when it comes to a belief about a controversial matter, there could easily be an apparently sound argument that the belief is false. But, often, if your knowledge can withstand this fact (which it can, the literature on disagreement notwithstanding), then it can withstand your discovering the apparently sound argument and finding it apparently sound.

This paper offers a new argument that your reasons for believing or acting need not be true. It proceeds indirectly through an account of what it takes to be happy that p. To be happy that p is for p to be among your reasons for being happy. That’s because questions about why you’re happy and what you’re happy is the case are interchangeable. But, I argue, it is possible to be happy that p even when p is false. In cases in which you believe falsely that p and sincerely assert that you are happy that p, you are still expressing happiness about something. To be happy about something is to be happy that some proposition is the case. In the cases in question, it is implausible that the proposition you are happy is the case is a proposition about the evidence or how things seem or what you believe. The only other option is that the proposition you are happy is the case is p itself. Along the way, I discuss linguistic data that seems to counter the view that you can be happy that falsehoods are true. Though initially suggesting a more principled argument that you can only be happy about truths, both the linguistic data and the principled argument can ultimately be defused. A similar principled argument for the factivity of ‘knows,’ however, remains happily untouched.

Modest Infinitism Jeremy Fantl Abstract Infinitism, a theory of justification most recently developed and defended by Peter Klein, is the view that justification is a matter of having an infinite series of non-repeating reasons for a proposition. I argue that infinitism is preferable to other theories (like foundationalism) in that only infinitism can plausibly account for two important features of justification: 1) that it admits of degrees and 2) that a concept of complete justification makes sense.
