Comprehensive and packed, Alvin Plantinga's two-volume treatise defies summary. The first volume, Warrant: Current Views, is a meticulous critical survey of epistemology today. Many current approaches are presented and exhaustively discussed, and a negative verdict is passed on each in turn. This prepares the way for volume two, Warrant and Proper Function, where a positive view is advanced and developed in satisfying detail. The cumulative result is most impressive, and should command attention for years to come. Here I cannot possibly do justice to the scope and richness of Plantinga's accomplishment. Given the limitations imposed by the occasion, I will discuss only what seem the most important and original proposals, and will compare them with some relevant alternatives.

The Twentieth World Congress of Philosophy was held in Boston in August 1998. Twice in this century has there been a philosophy world congress in the United States, both times in Boston. Congresses have long been held every five years, but mostly in France, Germany, Russia, England, and other European countries. Aside from the two in this country, only one had previously been held in the Americas, in Mexico. The organization responsible for holding such congresses is, and has long been, the Federation International de Societes de Philosophie.

What modal relation must a fact bear to a belief in order for this belief to constitute knowledge of that fact? Externalists have proposed various answers, including some that combine externalism with contextualism. We shall find that various forms of externalism share a modal conception of “sensitivity” open to serious objections. Fortunately, the undeniable intuitive attractiveness of this conception can be explained through an easily confused but far preferable notion of “safety.” The denouement of our reflections, finally, will be to show how replacing sensitivity with safety makes it possible to defend plain Moorean common sense against the spurious advantages over it claimed by skeptical, tracking, relevant-alternative, and contextualist accounts.

Since this paper is for a conference on “Contextualism in Epistemology and Beyond,” I have opted to sketch a retrospective of contextualism in epistemology, including highlights of the “relevant alternatives” approach, given how relevantism and contextualism have developed in tandem. We focus on externalist forms of contextualism, bypassing internalist forms such as Cohen 1988 and Lewis 1996, but much of our discussion will be applicable to contextualism generally. Internalist contextualism is helpfully discussed in papers by Stewart Cohen, Richard Feldman, and Jonathan Vogel, in Tomberlin 1999.

Life may turn sour and, in extremis, not worth living. On occasion it may be best, moreover, to lay down one's life for a greater cause. None of this is any news, debatable though it may remain, in general or case by case. Now comes the news that life does not matter in the way we had thought. No resurgence of existentialism, nor tidings from some ancient religion or some new cult, the news derives from the most sober and probing philosophical argument (the extraor- dinary Parfit, 1984, Part III), and takes more precisely the following form: Even though life L is optimal (in all dimensions), and even though if it were extended L would continue to be optimal, it does not follow that it is best to extend it, even for the subject whose life L is. What is the argument? Section II will defend a certain view of the nature of persons and personal identity, and Section III will then argue for the Paradox on that basis, and reflect on its philosophical implications and on the options it presents.

Belief is considered a kind of performance, which attains one level of success if it is true (or accurate), a second level if competent (or adroit), and a third if true because competent (or apt). Knowledge on one level (the animal level) is apt belief. The epistemic normativity constitutive of such knowledge is thus a kind of performance normativity. A problem is posed for this account by the fact that suspension of belief seems to fall under the same sort of epistemic normativity as does belief itself, yet to suspend is of course precisely not to perform, certainly not with the aim of truth. The paper takes up this problem, and proposes a solution that distinguishes levels of performance norrmativity, including a first order where execution competence is in play, and a second order where the performer must assess the risks attendant on issuing a first-order performance. This imports a level of reflective knowledge that ascends above the animal level.

According to nomological accounts of causation causal connections among events or states must be mediated by contingent laws of nature. Three types of causal connection are cited and discussed in opposition to such nomological accounts: (a) material causation (as when a zygote is generated by the union of an ovum and a sperm); (b) consequentialist causation (as when an apple is chromatically colored as a result of being red); (c) inclusive causation (as when a board is on a stump in consequence of its having been placed there by a carpenter). These are all source-consequence relations or result-yielding relations and they are all cases of necessitation, each with its own distinguishing features.
