ATOMICITY AND EXTENSION
Chris van Haeften

Abstract
The general ontic structure of the fully concrete res verae is the structure of an occurring event (actual occasion). Both in its aspect of occurring duration, as well as in the aspect of its characteristic pattern, it is bound to the general condition of extension. Its occurring extendingness leads to and results in the extendedness of its characteristic pattern.

This characteristic pattern is only finally determinate in the satisfaction of the occasion. It is of the nature of a (complex) object. That is to say that it can be recognized. This means that it is an orderly appearance. It relates the occasion to the order of the universe and determines its species. During the occurrence of the occasion, it functions as regulative final end (subjective aim).

Thus it plays a role both in anticipation as well as in retrospect. Being an object, it is atomic, and as such it is responsible for the atomic aspect of reality. This atomicity, however, in no way derogates from the continuity which is implied in the extensiveness of all becoming and transition. Only by combining the theory of events with the theory of objects can the puzzles in the relation between continuity and atomicity be solved.

1. Introduction
The formal structure of Whitehead's "actual occasion" has raised many questions. It seems as if Whitehead attributes contradictory properties to actual occasions. On the one hand, they are said to be not in physical time (Process 283); on the other hand Whitehead says that they are temporal ("Time" 242). This apparent contradiction points to a general problem which implies many closely related sub-questions. For example, to mention just a few of a them:

- What is the general relation of the actual occasions to time? Is time "in" the actual occasions or are the actual occasions "in" time? Are they in physical time? What actually is meant by physical time?
- Does the finality and atomicity of the actual occasions mean that they are not temporally extensive?
- If time is excluded from the actual occasions, then how can the succession of actual occasions in an enduring object form a uniserial time-system?
- Is the genesis of the actual occasion to be understood as a complex unity with an internal diversity?
- If so, is this diversity a diversity of phases? What is the relation between these phases? Are they successive? Or does the atomicity of the actual occasions mean that there can be no internal succession?
- Does the atomicity of the actual occasions mean that there is a discontinuity in the succession of them in an enduring object?

In the present article we will focus on the first four of these questions. They all circle around the epochal nature of the actual occasion. Many writers have been stirred into action by them. The interpretations, as well as the solutions for the difficulties are quite diverse. Chappell , Sipfle , Wallack , Christian , Ford , and Neville have all given important contributions. Though most of these views were expressed quite some time ago, they are still relevant since they give shape to the basic questions involved. Therefore, although I believe that these writers have missed the key to the solution, namely the relation between events and objects, I will discuss the views of some of them before explaining my own.
