In Chapter 4 of [2] Grünbaum sets out to refute Einstein's philosophy of physical geometry. The latter's theory is seen as lying within the tradition of "anti-empiricist conventionalism" of Duhem and Quine as opposed to the "qualified empiricism" of Poincaré, Carnap and Reichenbach. Consequently Grünbaum sets the stage for his critique of Einstein by discussing certain of the views of these other thinkers. But in these preliminary discussions the various theses are confused and misrepresented in such a way as to (...) make it almost impossible to evaluate Grünbaum's final treatment of Einstein's thesis. For this reason I will deal only with those parts of this chapter in which the roots of Grünbaum's confusion are to be found. This will involve analyses of two theories which are not clearly distinguished by Grünbaum. The first is Duhem's denial of the "crucial experiment" in physics; the second is Quine's version of "pragmatism.". (shrink)

The first part is an account of the Trinity Controversy, centering on the question of the identity of persons, and of the respects in which points made in the controversy, in particular the circularity objection, may have influenced Locke’s formulation of his theory. The second part argues that Locke is attempting to come to grips with the circularity problem, but that his solution is ultimately a failure. The argument of II, xxvii, 13 is analyzed in detail and the form of (...) Locke’s theory of relative identity is discussed. Fundamental difficulties are found to reside in his theories of representation and agency. (shrink)

In this paper I will deal with two questions. One is the relatively specific issue of whether mandatory retirement is unjust discrimination against the aged. The position taken is that it is not. But in the development of this argument a principle is advanced which appears to have the consequence that nothing, or at least very few of the practices that we are intuitively inclined to regard as unfair discrimination, are discriminatory with respect to age.

The article is an examination of locke's theory of personal identity in terms of his underlying commitment to a substance/property metaphysics. it is argued that the resources for his solution must be drawn from his theory of properties (modes), which are fully instantiated properties (or 'aspects'). locke raises the important problem of the identity of modes through time. his solution is outlined and criticized. the failure of his theory is diagnosed in terms of the intractability of the problem given his (...) underlying metaphysics.

The central problem burdening common sense pluralism, as well as motivating the various Ockhamist reactions, is what has come to be called the problem of coincidence. Everyday thought and speech refer both to seals and to sealing wax, to kings and to human beings or bodies. Where the first coincides completely in space with the second, is there one object in that place, or two? The initial response of common sense is perhaps to dismiss the latter out of hand. The (...) king is a human, after all, and the seal a quantity of sealing wax. But once we note that the conditions for the persistence in time of such objects may differ, or that they differ in essential properties, the one-object option seems less appealing. If both exist, as pluralism asserts, and the seal can be destroyed without the wax ceasing to exist, then perhaps the best defense of common sense is to recognize that the seal and the sealing wax are two.
