Summary:It is intuitively clear that putting the cart before the horse is not the same as putting the horse before the cart. It is equally clear that a history of philosophy is different from a philosophy of history. Yet there is no logical relationship, like the AND/OR/NOT functions, which would enable manipulation of these permuted, non-commutative, relationships. In this paper we present a system for automatic handling of ordered sets, states based on these sets, and of differing points of view regarding a Universe of Discourse. We call what we are dealing with aspects and we represent them by means of a new logical function called the Overlap function.
