Ernest Sosa's latest epistemology remains a version of virtue epistemology, and I argue here that it faces two central problems, pressing a point I have made elsewhere, that virtue epistemology does not present a complete answer to the problem of the value of knowledge. I will press this point regarding the nature of knowledge through variations on two standard Gettier examples here. The first is the Fake Barn case and the second is the Tom Grabit case. I will argue that Sosa's latest virtue epistemology fails to handle either case acceptably, and that as a result, cannot explain the value that knowledge has over that of the sum of any of its proper subparts. La última epistemología de Ernest Sosa continúa siendo una versión de epistemología de las virtudes, y siguiendo con una idea que ya planteé en otra parte, aquí argumento que afronta dos problemas centrales: que la epistemología de las virtudes no presenta una respuesta completa al problema del valor del conocimiento. Insistiré en esta idea sobre la naturaleza del conocimiento mediante variaciones de dos ejemplos estándares tipo Gettier. El primero es el caso del granero falso y el segundo es el caso de Tom Grabit. Argumentaré que la última epistemología de las virtudes de Sosa no maneja ninguno de estos casos de forma aceptable, y en consecuencia no puede explicar el valor que tiene el conocimiento por encima del de la suma de cualesquiera de sus propias partes.

This chapter explores the challenge to the proof of Fitch’s results presented by intuitionism, and the prospects of this viewpoint in avoiding the paradox that results. It argues that adopting intuitionistic principles of reasoning will not help avoid the paradox. It merely changes what is paradoxical from a lost distinction between known truth and knowable truth, to a lost distinction between unknown truth and unknowable truth. Since paradox remains in both cases, the solution to the paradox must be found elsewhere.

Motivated by Plantinga's work, fourteen prominent philosophers have written new essays investigating Plantingian warrant and its contribution to contemporary epistemology. The resulting collection, representing a broad array of views, not only gives readers a critical perspective on Plantinga's landmark work, but also provides in one volume a clear statement of the variety of approaches to the nature of warrant within contemporary epistemology and to the connections between epistemology and metaphysics.

The point of this essay by Jonathan Kvanvig is to draw three threads into a common cord to show what a fully fallibilistic approach to rationality ought to look like. The three threads concern what it is for rationality to be perspectival, why rational disagreement can always arise even when controls are in place for total evidence and competency, and why fallibility does not fly in the face of a strong preference for full unity in an account of normativity. The goal then is to provide an account of normativity that has no need of an independent notion of excusability (though of course there will still be excusable actions and beliefs) and no tendency to sniff the air for the scent of irrationality when people disagree.

One response to the preface paradox—the paradox that arises when each claim in a book is justified for the author and yet in the preface the author avers that errors remain—counsels against the preface belief. It is this line of thought that poses a problem for any view that places a high value on intellectual humility. If we become suspicious of preface beliefs, it will be a challenge to explain how expressions of fallibility and intellectual humility are appropriate, whether voiced verbally or encoded mentally. Moreover, banning expressions of intellectual humility is especially disturbing in our context, for such a preface claim is just the sort of expression of intellectual humility that is supposed to provide a barrier to the costly damage that can be done by zealous faith found in various forms of fundamentalism. The goal is thus to find a way to express humility without engendering paradox.

Philosophical reflection concerning heaven and hell has focused on the place of such doctrines in the great monotheistic religions emanating from the religion of the ancient people of Israel--Christianity, Islam, and Judaism. The philosophical issues that arise concerning these doctrines is not limited to such traditions, however. Consider, for example, the doctrine of hell. Any religion promises certain benefits to its adherents, and these benefits require some contrast that befalls, or might befall, those who fail to adhere to the religion in question.

Epistemologists often offer theories of justification without paying much attention to the variety and diversity of locutions in which the notion of justification appears. For example, consider the following claims which contain some notion of justification: B is a justified belief, S's belief that p is justified, p is justified for S, S is justified in believing that p, S justifiably believes that p, S's believing p is justified, there is justification for S to believe that p, there is justification for S's believing p, and S has a justification for believing that p. In addition to these passive uses of the notion of justification, there are active uses as well: S justified his belief in p, believing e justifies believing p, etc. The syntactic variety involves semantic difference as well. For example, the proposition S has a justification for believing that p does not entail that S believes p, whereas the proposition S justifiably believes that p does entail that S believes p. Our ultimate goal is to show that this diversity is only superficial by arguing that there is a basic kind of justification. On the way, however, we shall argue that there are three central uses of a notion of justifica- tion in the above list: propositional justification (as in p is justified for S), personal justification (as in S is justified in believing that p) and doxastic justification (as in S's believing p is justified). Our preliminary argument will be that the multiplicity above can be explained in terms of these three locutions, and the substance of our argument will be to show that one of these three is the basic kind of justification. Success in this task will thereby justify, at least in part, the practice of contem- porary epistemologists. Our conclusions, however, shall not be of much comfort to contemporary epistemology, for the way in which the apparent diversity in the uses of the notion of justification is eliminated undermines much of recent epistemology.
