Jonathan L. Kvanvig

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.

THE DOCTRINE OF omniscience has been understood in two ways. Roughly, it has been taken either as the claim that God knows all that is true (Geach, Kvanvig 1986) or as the claim that God knows all that can be known (Swinbume; Mavrodes). The first construal I shall call the traditional construal, and the second I shall call a limited construal. Though the traditional construal would seem to be the natural one to hold, considerations of the analogy between the best construals of the doctrine of omnipotence have suggested to some that a limited construal is prefera)1e. In particular, some have claimed that one should be careful to construe the doctrine of omnipotence, not as the..

Some recent philosophers of religion have addressed the question of how, and whether it is possible, that the religious experiences some persons have had can give reasons for believing that God exists. Swinburne, for example, claims that what he calls the principle of credulity implies that the religious experiences of those that have them do provide evidence for others that God exists. He formulates the principle as follows: 1 (1) if it seems (epistemically) to a subject that x is present, then probably x is present (all else being equal).

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.
