The theory of descriptions revisited
1988
Notre Dame Journal of Formal Logic
An excursus is carried out through the principal steps in the development of the theory of descriptions (TD) from B. Russell until now, and its most important advantages and disadvantages are sketched. TD is studied in the context of model theory (in A. Robinson's style), taking preservation and classification theorems based on normal forms into consideration. Finally, the categorical formulation of TD in topos theory, starting from M. Fourman and D. Scott, is presented with reference to sheaves.
