I distinguish two broad approaches to vagueness that I call "robust" and "wimpy". Wimpy construals explain vagueness as robust (i.e., does not manifest arbitrary precision); that standard approaches to vagueness, like supervaluationism or appeals to degrees of truth, wrongly treat vagueness as wimpy; that vagueness harbors an underlying logical incoherence; that vagueness in the world is therefore impossible; and that the kind of logical incoherence nascent in vague terms and concepts is benign rather than malignant. I describe some implications for logic, semantics, and metaphysics

In “Generalized Conditionalization and the Sleeping Beauty Problem,” Anna Mahtani and I offer a new argument for thirdism that relies on what we call “generalized conditionalization.” Generalized conditionalization goes beyond conventional conditionalization in two respects: first, by sometimes deploying a space of synchronic, essentially temporal, candidate-possibilities that are not “prior” possibilities; and second, by allowing for the use of preliminary probabilities that arise by first bracketing, and then conditionalizing upon, “old evidence.” In “Beauty and Conditionalization: Reply to Horgan and Mahtani,” Joel Pust replies to the Horgan/Mahtani argument, raising several objections. In my view his objections do not undermine the argument, but they do reveal a need to provide several further elaborations of it—elaborations that I think are independently plausible. In this paper I will address his objections, by providing the elaborations that I think they prompt.

The chapter rehearses the main outlines of gatekeeping contextualism—the view that it is central to the concept of knowledge that attributions of knowledge function in a kind of epistemic gatekeeping for contextually salient communities. The case for gatekeeping contextualism is clarified within an extended discussion of the character of philosophical reflection. The chapter argues that normatively valenced, evaluative concepts constitute a broad class of concepts for which a sociolinguistic point or purpose may be readily sensed—and for which the intimate connection between point/purpose and the concept itself is readily understandable. Commonly at the inception of philosophical reflection one’s sense for the point or purpose of a specific concept is seldom highly articulate. The chapter argues that this does not prevent one’s grasp of point/purpose from doing real work in philosophical reflection.

There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to (most) moral questions, and the possibility of knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

We respond to the central concerns raised by our commentators to our book, The Epistemological Spectrum. Casullo believes that our account of what we term “low-grade a priori” justification provides important clarification of a kind of philosophical reflection. However he objects to calling such reflection a priori. We explain what we think is at stake. Along the way, we comment on his idea of that there may be an epistemic payoff to making a distinction between assumptions and presumptions. In the book, we argued that an epistemically important form of nonaccidental reliability can be understood as a matter of processes being “transglobally reliable under modulational control.” Graham recommends another form of nonaccidental reliability, one rooted in evolutionary etiology. We explain why we think that the reliability of perceptual processes is best understood as turning of the kinds of modulational control that we highlight. We clarify how this approach represents a kind of reasonable epistemic patience—modulational control takes time, as it must turn on agents generating information about their own capacities and foibles. Lyons raises interesting questions regarding how (what we term) morphological content possessed by the agent can do the work that we set for it. We argue that it is necessary in order for agents to accommodate the background information that is relevant to many central problems of belief formation. We clarify how it can be expected to work

David Marr provided an influential account of levels of description in classical cognitive science. In this paper we contrast Marr'ent with some alternatives that are suggested by the recent emergence of connectionism. Marr's account is interesting and important both because of the levels of description it distinguishes, and because of the way his presentation reflects some of the most basic, foundational, assumptions of classical AI-style cognitive science. Thus, by focusing on levels of description, one can sharpen foundational differences between classicism and potential non-classical conceptions of mentality that might emerge under the rubric of connectionism.

In recent years, defenses of moral realism have embraced what we call new wave moral semantics', which construes the semantic workings of moral terms like good' and right' as akin to the semantic workings of natural-kind terms in science and also takes inspiration from functionalist themes in the philosophy of mind. This sort of semantic view which we find in the metaethical views of David Brink, Richard Boyd, Peter Railton, is the crucial semantical underpinning of a naturalistic brand of moral realism that these philosophers favor--a view that promises to deliver a robust form of moral realism. We argue that new wave moral semantics leads, in one way or another, to moral relativism--a view that is incompatible with the kind of moral realism these philosophers aim to defend.

In recent years Jaegwon Kim has propounded and elaborated an influential theory of events. He takes an event to be the exemplification of an empirical property by a concrete object at a time. He also has proposed and endorsed a version of the “Humean” tradition concerning causation: the view that causal relations between concrete events depend upon general "covering laws." But although his explication of the covering-law conception of causation seems quite natural within the framework of his theory, it gives rise to a serious problem: in numerous garden-variety instances of causation, the Humean conditions are not satisfied. In this paper I shall suggest a way to modify Kim's theory of events in order to reconcile it with his treatment of causality.
