Terry Horgan University of Memphis In this paper I address the problem of causal exclusion, specifically as it arises for mental properties (although the scope of the discussion is more general, being applicable to other kinds of putatively causal properties that are not identical to narrowly physical causal properties, i.e., causal properties posited by physics). I summarize my own current position on the matter, and I offer a defense of this position. I draw upon and synthesize relevant discussions in various <blockquote> [1] </blockquote> other papers of mine (some collaborative) that bear on this topic

In this critical study I first summarize Crispin Wright's "Truth and Objectivity". Wright maintains (1) that truth- aptness of a given discourse is neutral about questions of realism and anti- realism concerning the discourse, but also (2) that such metaphysical questions largely turn on discourse- specific constraints governing the truth- predicate. I urge a distinction between (i) Wright's general approach to truth and objectivity, and (ii) his apparent inclination to implement and the approach by construing truth as a fundamentally epistemic notion. I argue against an epistemically reductive implementation, and I briefly sketch an alternative way to implement the book's core ideas

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

J. L. Mackie argued that if there were objective moral properties or facts, then the supervenience relation linking the nonmoral to the moral would be metaphysically queer. Moral realists reply that objective supervenience relations are ubiquitous according to contemporary versions of metaphysical naturalism and, hence, that there is nothing especially queer about moral supervenience. In this paper we revive Mackie's challenge to moral realism. We argue: (i) that objective supervenience relations of any kind, moral or otherwise, should be explainable rather than sui generis; (ii) that this explanatory burden can be successfully met vis-à-vis the supervenience of the mental upon the physical, and in other related cases; and (iii) that the burden cannot be met for (putative) objective moral supervenience relations.

Josep Corbi raises several worries about the metaethical position that Mark Timmons and I have articulated and defended, which we call “nondescriptivist cognitivism.â€â€¦ His remarks prompt some points of clarification…. Timmons and I characterize descriptive content as “way-the-world-might-be†content. We maintain that “base case†beliefs—roughly, those non-evaluative and evaluative beliefs whose contents have the simplest kinds of logical form—are of two types: a non-evaluative belief is an is-commitment with respect to a core descriptive content, and an evaluative belief is an ought-commitment with respect to a core descriptive content. Core descriptive contents are those descriptive contents expressible by (nonevaluative) atomic sentences. Concerning the notion of a core descriptive content, Corbi says.

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.
