Paper Summary

Author’s Introduction

  1. The logical theory of sets obscures commonplace distinctions which we make between assortments, collections, and classes; in particular, those commonplace uses where we speak of collections of physical objects.
  2. In this paper, I shall suggest that the puzzles generated by assimilating ordinary collections to classes reflect the same difficulties as those which follow from equating proper names with definite descriptions.
  3. An indication will also be given as to how, within an alternative logical framework, these distinctions may be articulated.
