ABSTRACT
This chapter aims to provide the way in which experience is initially polarized into subject and object philosophers can pass on to the examination of another distinction which is discoverable within each. This is the difference between structure and process. The fluctuating character of objective appearances is, of course, in part due to the instability of the subjective activity which observes them. The continuity of any object with the world continuum, and the permanence of its place in that continuum, is therefore conditions of the intelligibility of that object. The kind of sensum philosophers experience depends almost entirely on the character of other objective processes, especially physical movements. Physical impacts from outside the body reach the brain by way of a wave of chemical change up an efferent nerve and bring about that complicated reaction which is aware-ness-of-sensum-and-space. Physical science teaches philosophers to regard the necessary continuity of motion as the essence of causation.
