Eric Olsen argues from the fact that we once existed as fetal individuals to the conclusion that the Standard View of personal identity in mistaken. I shall establish that a similar argument focusing upon dead people opposes Olson's favored Biological View of personal identity.

Two recent papers by Michael Burke bearing upon the persistence of people and commonplace things illustrate the fact that the quest for synchronic ontological economy is likely to encourage a disturbing diachronic proliferation of entities. This discussion argues that Burke's promise of ontological economy is seriously compromised by the fact that his proposed metaphysic does violence to standard intuitions concerning the persistence of people and commonplace things. In effect, Burke would have us achieve synchronic economy (rejection of coincident entities) by (...) postulating strongly counterintuitive transtemporal claims of numerical diversity. The argument is made that the price of Burkean economy is too high. (shrink)

We are confronted by a metaphysical problem and discover, to our dismay, that standard proposals for its resolution have strongly counterintuitive corollaries. That naturally encourages consideration of previously overlooked or neglected ways out of the problem. As it turns out, one of these unorthodox proposals has a leg up on the various standard ways out of our problem. Metaphysical progress.

By an incomplete sentence we shall understand a declarative sentence that can be used, without variation in its meaning, to make different statements in different contexts. Although the point deserves supporting argument, which we will not provide, sentences whose grammatical subjects are indexical expressions or demonstratives are obvious, plausible examples of incomplete sentences. Uttered in one context the sentence ‘He is ill’ may be used to make one statement, for example, that George is ill, while in another context the very (...) same sentence may be used to make a quite different statement, for example, that Paul is ill.

Commonplace things such as hawks and handsaws pose philosophical problems at least as imposing as those presented by abstract objects such as numbers and divine beings. Van Inwagen's metaphysic of material beings emerges from what he perceives to be the proper answer to the Special Composition Question, which is, roughly, the following: Under what conditions do various things compose a single thing? The first eight sections of the book address and dismiss various extreme and moderate proposals for resolving this question. (...) Van Inwagen argues vigorously for the view that our world contains, aside from mereologically "simple" entities, only living organisms, the activity of whose various parts constitutes a life. Strictly speaking, there are no tables, chairs, ships, or handsaws. A handsaw is merely a "virtual" and not a genuine object, whereas my cat is a genuine and not merely a virtual object. Felines and humans and other macroscopic individuals are composed of various cells, which themselves are composed of simples, whereas the nonentity that is my bicycle is merely virtually composed of various macroscopic and microscopic virtual objects. Van Inwagen argues that none of this contradicts our ordinary beliefs about the world we inhabit. Although there are, strictly speaking, no inanimate objects other than simples, there are various simples that are arranged bicycle-wise and still other simples arranged ship-wise. It is a corollary of van Inwagen's answer to the Special Composition Question that such simples compose nothing. Since there is nothing such simples compose, there really are no such things as bicycles and ships. Artisans do not create in the sense of causing things to exist, but only rearrange simples in ship-like and table-like ways. The situation is different when we consider biological conception and the emergence of a human life. In this case, but not in artifact cases, a new individual arrives on the cosmic stage. Van Inwagen argues that conception leaves us with "a new individual" which itself perishes when it divides. You were never a zygote, since you presently exist, although your zygote--the zygote from which you developed--does not. It is argued that lives are "infected with vagueness at both ends." In various borderline cases, there are simples such that there is simply no correct yes or no answer to the question, Does the activity of these simples constitute a life? Accordingly there is no determinate answer to the question, Do these simples compose something? Van Inwagen argues against the Linguistic Theory of Vagueness and offers a detailed defense of the vagueness of identity. In cases of vague diachronic identity, there is a sense in which the transitivity of identity principle fails. Starting with premises that are half-truths, this principle may in certain cases license a false conclusion. (shrink)

Four non-Cartesian conceptions of a person are considered. I argue tor one of these, a position called animalism. I reject the idea that a (human) person coincides with, but is numerically distinct from, a certain human animal. Coinciding physical beings would both be psychological subjects. I argue that such subjects could not engage in self-reference. Since self-reference (or the capacity tor self-reference) is a necessary condition for being a person, no physical subject coincident with another such subject can be a (...) person. I take all of this to support the view that we (human persons) are identical with human animals. (shrink)

In The Nature of Necessity, Alvin Plantinga asserts that “the number 7 exists necessarily and Socrates does not.” This is, to my way of thinking, reasonable enough. Unhappily, cannot be reconciled with Plantinga's further claims that an object x has a property P essentially or necessarily if and only if x has P in every world in which x exists and existence is itself, although not “an ordinary property,” nevertheless a property.
