“‘Conscious selection of a purpose’ is one way of describing a particular process, and after this process has occurred the brain will be different from before. The old theories of the correlation or interaction of mind and matter presupposed that they were separate things in themselves. The important questions become quite different when one realizes that mind and matter do not exist independently, but that they are both somewhat inadequate ways of describing certain _aspects_ of one organic process. The spatial aspect of organic process is called the physical organism. The temporal aspect of organic process corresponds to the content of its consciousness. The physical body is a group of spatial characteristics. Consciousness is a system of temporal elements; memory, anticipation, deliberate repetition, creative longing, hope and fear are all things set in time. “Professor Alexander has said ‘Time is the mind of Space.’ He attempts to explain space and time by an anthropomorphic analogy. It is a very suggestive idea, though for the searcher whose goal is the nature of consciousness itself it is more valuable to put it the other way round: mind is the temporal aspect of process, body the spatial aspect. But it is very important indeed to notice that we have not yet found the adequate terms for describing these two aspects of process. Matter is unsatisfactory for the spatial aspect, because there are no unchanging particles. But nor is mind sufficient for the temporal aspect, because there is a temporal aspect to the combination of hydrogen atoms and to chemical and colloidal processes, and yet we must not speak of these as having mind. When the new words for these two aspects are invented they will form the foundation of the scientific synthesis which I am expecting.” To which the psychologist may answer: “Well, at heart I have always been a thorough-going determinist like you, at least in dealing with my patients. Moreover I find it works, because I have always included in my picture of the patient a life-impulse of some sort, which can be influenced by my personality. Thus if the behaviour of my patient is absolutely determined, the conditions which determine what happens to him include some inner life tendency, and also the effects produced on him by all the people he meets. “But if one attempts to formulate such an absolute determinism, or to apply it to oneself, one gets into deep waters, and I haven’t the courage to try it. It seems you must be right at bottom, but that only a god could believe it without its upsetting his mental balance or his sense of moral responsibility.”
