Abstract

The problem of the subject-predicte distinction has featured centrally in much of modern philosophy of language and philosophical logic. and the distinction is taken as basic or fundamental in modern philosophical logic. A sortal is a symbol which furnishes a principle of distinction and counting in its own right for particulars (objects).This book explores sortals and their relationship to the subject-predicate distinction; arguing that the nature of sortal symbols has been misconstrued in much modern writing in the philosophy of logic by failing to clearly distinguish sortals from names and predicates; contending that this misconstruction has led to a failure to appreciate what makes the subject-predicate distinction possible; demonstrating logical difficulties which then follow; and expounding an account of sortal symbols which seeks to be immune from the difficulties. Exploring and challenging aspects of the work of Frege, Russell, Geach, Quine, Evans and Strawson, amongst others, Durrant also provides a new challenge to certain popular presuppositions employed in many areas of contemporary philosophical debate, and offers important insights for those studying across philosophical logic, philosophy of language, and metaphysics and epistemology, in particular.
