Both philosophers of perception and analytic metaphysicians apply the tropes/universals distinction when considering the ontological status of visual properties. One way of arguing in favor of the trope interpretation of visual properties is to claim that the way in which we visually experience properties makes it plausible to characterize them as tropes. In this paper, I argue for a different position, namely that the way in which we visually experience properties provides a serious challenge for the trope interpretation, but not (...) for an interpretation in terms of universals. More specifically, I claim that the trope interpretations of visual properties have problems accounting for the fact that ordinary, veridical visual experiences can present the properties of two objects as strictly similar.

This article includes a basic overview of possible world semantics and a relatively comprehensive overview of three central philosophical conceptions of possible worlds: Concretism (represented chiefly by Lewis), Abstractionism (represented chiefly by Plantinga), and Combinatorialism (represented chiefly by Armstrong).

We discuss the one–many problem as it appears in the Philebus and find that it is not restricted to the usually understood problem about the identity of universals across particulars that instantiate them (the Hylomorphic Dispersal Problem). In fact some of the most interesting aspects of the problem occur purely with respect to the relationship between Forms. We argue that contemporary metaphysicians may draw from the Philebus at least three different one–many relationships between universals themselves: instantiation, subkind and part, and (...) thereby construct three new ‘problems of the one and the many’ (an Eidetic Dispersal Problem, a Genus–Species Problem, and an Eidetic Combination Problem), which are as problematic as the version generally discussed. We then argue that this taxonomy sheds new and interesting light on certain discussions of higher-order universals in recent Australian analytic philosophy. (shrink)

It is commonly held that Bradley’s regress has a solution within a trope ontology. This seems to happen when a bundle is understood as constituted by non-transferable tropes. It also seems to happen when a bundle is understood as constituted by transferable tropes related by a relational trope of compresence whose existence specifically depends on those relata. In this article I demonstrate that these proposals fail in addressing the essential question that underlies the regress, incurring in a question-begging response already (...) anticipated by Bradley.

Whereas traditional nominalists accept the realist's challenge to solve a 'Problem of Universals', the Ostrich Nominalist responds that there is no such Problem to answer. I suggest that Ostrich Nominalist arguments expose a genuine flaw in the realist project. However, I argue, Ostrich Nominalism is ultimately defeated by a problem about the analysis of qualitative sameness and difference. Qualitative sameness and difference are adequately understood only as sameness or difference in some respect. The need to say what these respects of (...) sameness and difference are (if not universals) constitutes a genuine Problem of Universals; consequently—I claim—the Ostrich Nominalist is mistaken.

The paper develops a unified account of both deterministic and indeterministic laws of nature which inherits the merits but not the defects of the best existing accounts. As in Armstrong's account, laws are embodied in facts about universals; but not in higher‐order relations between them, and the necessity of laws is not primitive but results from their containing chances of 0 or 1. As in the Ramsey‐Lewis account, law statements would be the general axioms and theorems of the simplest deductive (...) theory of everything; but because laws are not so defined, simplicity of statement is not a criterion of law‐hood.

Le nominalisme est « le refus d'admettre toute entité autre qu'indivi-duelle ». II doit, pour justifier la simplicité de son ontologie, proposer une théorie de laconnaissance et une théorie sémantique qui ne présupposent ni l'une ni l'autre l'existence réelle des univer-saux. Certaines des voies qui s'ouvrent à cette entreprise délicate ont été systématiquement explorées vers la fin du Moyen Age et il y a tout à parier que, malgré les ruptures épistémologiques, les révolutions scientifiques et autres changements d'epistémè, les nominalistes (...) contemporains pourraient encore profiter de quelque façon de l'immense travail théorique accompli par leurs prédécesseurs médiévaux. C'est dans cet esprit que je voudrais procéder à une reconstruction sommaire de la théorie sémantique avancée au début du quatorzième siècle par le Fran-ciscain Guillaume d'Occam. Je ne m'engagerai pas dans une comparaison détaillée entre Occam et les auteurs contemporains, mais j'essaierai de présenter sans en trahir l'esprit la sémantique occa-miste de manière à en faire apparaître la pertinence pour les débats actuels. II serait possible, me semble-t-il, d'aller encore plus loin dans cette voie en mettant à profit les techniques formelles récentes pour axiomatiser la théorie d'Occam. Pour l'instant cependant, je me limiterai à une présentation plutôt informelle. (shrink)
