Abstract

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.
