your thought. Equally plainly it is there and then, or it would not be the thought of this morning's breakfast. It is therefore both. Now a state of consciousness conditioned by two mutually exclusive opposites is unconditioned by either. In other words, your thought is unconditioned by space and time. By what, 'then, is it conditioned ? The answer is as important as it is obvious.

This we call memory. Or, if we like, we can increase or diminish or alter it in any particular. For coffee and rolls, we may substitute ortolans and peacocks' tongues, and so on. There is no limit to it. This we call imagination; and what I want to emphasize is that memory and imagination are identical in being states of consciousness produced by the will, and differ only in the closeness of their correspondence with antecedent states.

First, from without, by matter acting on matter, either through contact, direct or indirect, or by means of vibrations, such as those of sound and light. This we may call, for convenience, thesensory origin of consciousness, since it involves direct relation through the senses with the g...
