This chapter explores the different grounds for accepting the claim that all truths are knowable, the assumption central to the derivation of Fitch’s result. It argues that although there is no compelling argument for holding that all truths are knowable, there are various positions in which this feature of semantic anti-realism fits naturally; rejecting this puts serious tension into a broad range of philosophical outlooks, including theism and physicalism. In the end, the paradox should be felt by everyone, even those who do not accept the knowability claim, because the heart of the paradox is not simply in what is implied by the knowability claim, but in a lost logical distinction between what is actual and what is possible.

This chapter examines the logical structure of the knowability paradox, presenting the details of the proofs that underlie the paradox, and clarifying which elements of these proofs give rise to paradox. It argues that there is no simple and obvious logical mistake in the derivation of the knowability result. A paradox has deep significance only if it arises from plausible premises. Those in question in Fitch’s proof are the claim of epistemic modesty, that some truths will never be known, and the knowability principle that all truths are knowable. Although the second claim does not have the same intuitive pull as the first, there are substantive grounds in its favour; grounds that some hold show that all truths are knowable, but which show at the very least that it is plausible to maintain that all truths are knowable.

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.

Jonathan Kvanvig presents a compelling new work in philosophical theology on the universe, creation, and the afterlife. Organised thematically by the endpoints of time, the volume begins by addressing eschatological matters and the doctrines of heaven and hell and ends with an account of divine deliberation and creation. Kvanvig develops a coherent theistic outlook which reconciles a traditional, high conception of deity, with full providential control over all aspects of creation, with a conception of human beings who are free and morally responsible. The resulting position and defense is labeled "Philosophical Arminianism," and deserves attention in a broad range of religious traditions.

Foundationalism came under attack in two areas in the first half of this century. First, some doubted whether the foundations were adequate to support the entire structure of knowledge, and second, the doctrine of the Agiven@ came under serious attack. = However, many epistemologists were not convinced that foundationalism was to be abandoned even if the criticisms were granted. According to these epistemologist, far from having shown that foundationalism itself was at fault, the critics of foundationalism had only been attacking one particular version of foundationalism--that version that included infallibility, incorrigibility,, or some appeal to a Agiven@ at the base of the structure of justification. The claim of these defenders was that there are other possible types of foundationalism than this version of foundationalism, which has come to be called Classical Foundationalism. And thus opened up a new area of philosophical lexicography: the attempt to say what foundationalism itself is, so that Classical Foundationalism turned out to be one instance of foundationalism but not the only possible one.

attacks new defenders of foundationalism. Some simply took on the critics, 2 but others attempted to argue that even if the critics were right, only one form of foundationalism was suspect, not foundationalism itself. For, according to these defenders, foundationalism is not to be identified with the view of Classical Foundationalism (CE) that all of our knowledge rests on incorrigible beliefs. Rather foundationalism is the view that all of our knowledge rests on beliefs that are self-warranting in some sense. Thus, even if CF is false, it does not follow that foundationalism is false.
