I have personal knowledge of a person who, by employing the principles of conscious control which I advocate, mounted and rode a bicycle down-hill without mishap on the first attempt, and on the second day rode 30 miles out and 30 miles back through normal traffic. This same person was also able to fence passably on first taking the foil into his hands. In each case the principles involved were explained to him and he carefully watched an exhibition, first analysing the actions and the “means whereby,” then reproducing them on a clearly apprehended plan. This, it seems to me, should be a normal, not an abnormal human accomplishment. Just as a cat by sheer instinct, the first time she essays to jump, gauges her powers and the distances with accuracy, so, with more reason and greater ease, the human subject, by employing consciously controlled intellect and kindred experience in place of instinct, should be able to direct his powers to a definite ordained end with less physical strain and less frequent physical repetition, i.e., “Practice.” In this connexion I have been often asked the difference between instinct and intuition. I define instinct as the result of the accumulated subconscious psycho-physical experiences of man at all stages of his development, which continue with us until, singly or collectively, we reach the stage of conscious control; whilst intuition is the result of the _conscious reasoned_ psycho-physical experiences during the process of our evolution. The word “subconsciousness” is but a formula for our habits of life. I hold strongly that when we shall have reached the state of conscious control in civilisation, and have established thereby new and correct habits, a new and correct subconsciousness will become established. I might here with advantage re-emphasise my view regarding the supreme importance of conscious control. Conscious control is imperative, as I have pointed out, because instinct in our advancing civilisation largely fails to meet the needs of our complex environment. Without conscious control the subject or patient may know he has defects, may know further what those defects are, may even know at what explicit improvement he is to aim, and yet may be quite unable by means of imitation or the orthodox and traditional methods of instruction to effect the desired end. With conscious control, on the other hand, true development (unfolding), education (drawing out), and evolution are possible along intellectual as against the old orthodox and fallacious lines, by means of reasoned processes, analysed, understood, and explicitly directed. Conscious control enables the subject, once a fault be recognised, to find and readily apply the remedial process.
