Wiggins recently proposed construing frege's 'unsaturated expressions' as containing two elements, Viz., (1) a copula and (2) a general term standing for a concept; but he argued that concepts, So understood, Were not to be identified with properties. While accepting the above division of 'unsaturated expressions', I argue, Contra wiggins, That concepts, So understood, Were precisely to be identified with properties.

Passages in Leibniz which have been understood to contain his statement of Leibniz law do not in fact contain any statement of that principle. Some of these passages contain a statement of the principle of the identity of indiscernibles, While others contain a statement of a principle about concept identity. The latter principle states that a concept, A, Is identical with a concept, B, If and only if a can be substituted for b in any proposition without change of truth (...) value. (shrink)

A natural picture to have of events and processes is of entities which extend through time and which have temporal parts, just as physical objects extend through space and have spatial parts. While accepting this picture of events, in this paper I want to present an alternative conception of processes as entities which, like physical objects, do not extend in time and do not have temporal parts, but rather persist in time. Processes and events belong to metaphysically distinct categories. Moreover (...) the category of events is not the more basic of the two. (shrink)
