Abstract

This paper attempts to correct certain misinterpretations of Whitehead's theory of eternal objects.  First I show that sensa and patterns are distinguished conceptually and not in terms of their supposedly divergent capabilities for ingression.  I go on to argue that the physical ingression of all eternal objects is governed by the requirement that they ingress polyadically.  [Abstract from The Philosopher's Index]
