The ‘theory of universals’ of St. Thomas Aquinas has been interpreted in one of two ways by most commentators. Traditionally, commentators have attributed to Thomas the theory which is usually also attributed to Aristotle: “moderate realism,” the view that universals exist in things, subject in some way to individuating principles in the things. For example, according to Copleston.

The phrase "identity in difference" has been regarded by some thinkers as a matter of mere mystery-mongering. How can differences nevertheless be identical? The phrase is transparently absurd.

In this article i defend the claim that an individual is no more and no less than a bundle of instances of properties against the following objections: (1) the concept of an instance of a property presupposes the concept of an individual. i argue that it presupposes only that no instance of a property exists independently of other instances. (2) if a thing were only a bundle of instances of properties, then properties would qualify properties. this objection commits the fallacy (...) of composition. (3) a bundle constituting an individual needs a component which is not a property to individuate it. i argue that such a bundle individuates itself. (4) the bundle theory makes change impossible. i argue against this claim by distinguishing a thing's numerical identity from its "complete" identity. (5) the bundle theory makes all true statements about individuals analytically true. i show that, at least for one interpretation of 'analytically true', this is not so. (shrink)

As a student and collaborator of Louis Agassiz on the study of fishes, F. W. Putnam gave promise of becoming a leading ichthyologist with special interest in taxonomy generally and the Etheostomidae in particular. While he was noted briefly in these fields, contributed a number of minor papers, and aided in the posthumous publications of some of Agassiz's work on fishes, he neither reached his original goal nor completed his major projected works. For in 1874 he switched careers and was (...) appointed Curator of the Peabody Museum of American Archaeology and Ethnology at Harvard University, and is remembered today primarily as a founder of American archaeology rather than as a systematic ichthyologist.

Late antiquity was a crucial period for the development of the Christian church. Christianity went from a persecuted to a favored religion; and after a period of internecine struggle, Nicene-Chalcedonian Christianity prevailed as orthodoxy throughout the Mediterranean world. Ancient sources and modern studies dealing with this period are replete with discussions of the church as it developed within the territorial confines of the Roman Empire. But both virtually ignore the barbarian churches that existed during the fourth through the sixth centuries, (...) which were often heterodox and, initially, located beyond the imperial frontiers.

While the members of the school of Logical Empiricism may differ in various details, nearly all of them are opposed to metaphysics on the ground that a scientific metaphysics is the only possible one. All philosophy is to become scientific. This assumption is based on their epistemological criterion of verifiability which appears to be a basic doctrine of this school. The implications of this doctrine have not been worked out in detail by many, but one of the most explicit accounts (...) has been given by A. J. Ayer in his book on Language, Truth and Logic, which can be taken as a representative work in its attack on metaphysics. (shrink)
