Abstract
The first six chapters of this book present and criticize six views of the nature of proper names, among which are theories that proper names have no meaning or connotation, that proper names have more meaning than other signs or that their meaning is infinite, that ordinary proper names should be analysed into "logically" proper names, etc. This part of the book is the best. One may find in these chapters several well-reasoned arguments which seem to totally demolish the theories under investigation. Chapters seven to nine present the author's own solution to the problem. Sørensen holds that a proper name does have a meaning—otherwise it would not have been a part of language at all. The meaning of a linguistic sign, he argues, is a set of conditions to be satisfied by an extra-linguistic entity, such that this entity may be identified as denoted by the said sign. A proper name is an individual name, and its meaning is a series of necessary and sufficient conditions for the identification of the individual entity which this name is intended to denote. It is Sørensen's view that this series consists of a definite description of final length including space and time indicators. The definiens formula for proper names is thus 'P' = 'the x that... t... p....' The discussion of this proposal is, however, greatly impaired by Sørensen's utter disregard for the rich philosophical literature existing on the subject: no attempt is made to confront his view with the now standard arguments against theories of that type. Even many inner difficulties of the proposed solution are ignored. E.g., one may ask what values do 't' and 'p' take in the definition of 'Zeus'. Or take the following puzzle: are 'The x that taught Aristotle in p at t' and 'The x that studied with Socrates in p at t' both the meaning of 'Plato'? Sørensen's view that "A national register may be looked upon as a dictionary of proper names" suggests a positive answer, but surely R and S cannot be the same meaning. Many similar problems bother the reader of Sørensen's book, but, unfortunately, they are nowhere discussed.—E. M. Z.
