It is conclusively established that the individual Self, in its normal state of relationship to the body, can receive and convey impressions only through the medium of the brain. Remove the brain and _mind_ ceases to be, although life may linger long. Extract a part of the brain and a part of “the mind” goes with it. This result is sometimes obscured by the fact, not sufficiently recognised by the Physician and the Mental Philosopher, that we have _two_ brains—two organs of Mind—one of which can act alone when the other is wholly or partially disabled. If a Dream be analysed, it is not difficult to trace the action of each separate faculty. The imagination supplies the picture, which we mistake for a reality because we have lost the means by which, when awake, we distinguish the mere mental creation from the impressions borne to us by the senses. Hence mental action precisely as if the ideal picture had been real as it is believed to be. The other mental faculties are called into play by the drama of the dream as they would have been by a living drama. It is not an imagined anger, or fear, or hate, that we feel in dream. The passions, emotions and sentiments are actually excited as they would be by the same objects presented when we are awake, only they are kindled by shadows created within and not by substances existing without. But Psychology will gather from the phenomena of dream some very important conclusions. In dream the Mind is awake and at work, but it works wildly, insanely, without self-control. Something is absent in sleep that controls its action when we are awake. That absent controlling and directing force is the WILL. What is THE WILL? The WILL is the expression of the SELF—of the INDIVIDUAL BEING. It is the “I”—the YOU—that commands, controls and directs thought and action. This Conscious Self, which possesses the power we call the _Will_, is not, and cannot be, the material brain, nor the product of the brain, as the Materialists assert; for we see that in Dream the brain is in part awake and working without the assistance or control of the Will; proving that the Self, of whom the Will is the expression, is not identical with the brain. Moreover, the Conscious Self, although taking cognizance of the action of the mind in dream, is nevertheless unable to direct its action; thus affording another proof that the Conscious Self and the material mechanism are not identical. The phenomena of Dream, then, are the _facts_ first presented in the scientific investigation of Psychology from which we derive physical _proofs_ of the existence of a _Soul in Man_, not as a vague theory merely, but as shown by the positive _evidence_ of his mechanism in action.
