Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

The aim of this article is to show that human persons belong, ontologically, in social ontology. After setting out my views on ontology, I turn to persons and argue that they have first-person perspectives in two stages (rudimentary and robust) essentially. Then I argue that the robust stage of the first-person persective is social, in that it requires a language, and languages require linguistic communities. Then I extend the argument to cover the rudimentary stage of the first-person perspective as well. (...) I conclude by enumerating ways in which human persons differ from nonhuman animals. (shrink)

Beginning with Aristotle, philosophers have taken artifacts to be ontologically deficient. This paper proposes a theory of artifacts, according to which artifacts are ontologically on a par with other material objects. I formulate a nonreductive theory that regards artifacts as constituted by - but not identical to - aggregates of particles. After setting out the theory, I rebut a number of arguments that disparage the ontological status of artifacts.

The Representational Theory of the Mind (RTM) has been forcefully and subtly developed by Jerry A. Fodor. According to the RTM, psychological states that explain behavior involve tokenings of mental representations. Since the RTM is distinguished from other approaches by its appeal to the meaning or "content" of mental representations, a question immediately arises: by virtue of what does a mental representation express or represent an environmental property like coto or shoe? This question asks for a general account of the (...) semantics of mental representation. Fodor places two conditions on the requisite theory: it must be physi calistic (that is, it must be couched in nonsemantic and nonintentional terms, free of expressions like "refers to" or "denotes" or "means that"), and it must be atomistic (that is, it must allow that the thinker can have a single intentional state without having any others). What is wanted, then, is a reductive theory that "naturalizes" content by specifying sufficient conditions, in physicalistic and atomistic terms, for a mental symbol to represent or express a certain property.

Mainstream analytic metaphysics is a priori metaphysics. It is hemmed in by basic assumptions that rest on no more than a priori intuitions. Jaegwon Kim's arguments about causation are a paradigm example of sophisticated arguments with little or no justification from the world as we know it. And Peter van Inwagen's arguments about material objects are motivated by a question that, I think, has no nontrivial answer: Under what conditions do some x's compose an object y? The trivial answers are (...) "always" and "never." Any other answer, including van Inwagen's, seems to me to be arbitrary—and again based on a priori intuitions. To cite two more examples that I find egregious: The assumption that there is a metaphysically important distinction between what is mind-independent and what is not, and the assumption that there is a metaphysically important distinction, among things that are real, between what is fundamental and what is not. A priori intuitions, especially when not shared by philosophers outside a small circle of specially trained people, seem a weak reed on which to hang metaphysical systems. (shrink)
