Abstract

It is not asserted that an actual occasion excludes other occasions in the sense that it is completely independent of or isolated from them. This is an element in the 'traditional' doctrine of substance which Whitehead regards as fundamentally false. Nor will exclusiveness be asserted in any sense which is incompatible with what I understand to be Whitehead's doctrine of objectification, which is his theory of how one actual entity is 'present in' another. Nothing could be clearer from Whitehead's writings than the fact that he means to say that actual occasions are 'present in' or included by other actual occasions. There is no intention of denying this obvious fact.
