This section is from the book "Stage Hypnotism - A Text Book Of Occult Entertainments", by Prof. Leonidas. See also: The New Encyclopedia of Stage Hypnotism.
Primarily, we are told, the mind expresses itself through the material brain in two ways: One is the conscious, or the Observation, the Will, the Judgment and the Senses, while the other is through phenomena that appear to be distinct from material causes: Telepathy, Clairvoyance, etc. The Conscious is the Every-Day Mind and the Sub-Conscious is the Sleep-Mind.
In sleep, we see strange things and believe that they exist. When we awake, we wonder how we could have believed anything so grotesque! What does this indicate ? Simply: This dream mind can deduce but it cannot reason back into a premise. It means, also, that it contains a perfect knowledge of all our acts, or experiences, and of everything we learn, either through the agency of experience or the routine of study. It is this mind that the hypnotist works on: He puts the conscious mind to sleep and suggests, his suggestions are received by the Sub-Conscious mind and are fulfilled. Thus, I tell a hypnotized person that he is a bird and he immediately believes that he has wings, that he can fly and do all that his perfect memory tells him a bird can do. I say he will do this, but I must add that he must be a somnambulistic or sleep-walking subject. But to the average person these little scenes produced by the stage hypnotist have become settled facts. We must now begin to see what this branch of psychology holds for the advancement of man, either through education, or the therapeutic application of suggestion, or of sleep-treatment.
I will assume that I have two subjects: One is told that he is a lecturer. This boy has never been before the public to speak in any manner. He apparently does not possess the least talent. But, while he sleeps I tell him that he is a wonderful orator; that the world awaits his debut in the field of oratory with wonder, admiration and great expectation. I drill into that subconscious mind - that mind that never sleeps, the mind that carries on through the agency of the nervous system all the processes of mortal life - the idea that he possesses talent. I tell him that he can speak and that he will speak. And, when he bows before the audience, they are charmed with the wonderful power of his oratory; they marvel at the force of the figures of speech he employs, they applaud him, not for the little act he is presenting in his dream-state, but because they realize that a great power is exhibited.
This little illustration teaches us the first lesson I wish to present: The awakening of latent talents. We cannot, through the agency of hypnotism nor of all the magic of the world, create something where there is nothing. If it can be done, we, as mortals, cannot do so. But we can awake the sleeper and, instead of his ability remaining concealed all his life, we bring it out, develop it and give him the power thus awakened.
Where this ability is more prominent; where it is not concealed, the Conscious mind realizes that it possesses talent and the person so endowed has a desire to develop it. Therefore, we will have two young ladies as our examples. The first one has a subconscious talent, but it is hidden so deeply that she gets only fleeting glimpses of it and does not feel that desire, that longing for a fuller knowledge along the lines of her subconscious ability. The second young lady has a firmer conscious hold of her ability. It may be music. She knows that she likes music and that she would like to play. As she is taught, she realizes that there is something in music that fills her with rapture. Thus she is bringing out her dormant abilities along this line. The first young lady may be hypnotized and, accidentally, I should say, her talent would be discovered. She would be given a conscious knowledge of the fact and she, too, would soon bring into warmth that innate love she possesses - a thing subconscious.
So it was that "Trilby" sprung into being. At the time the book appeared the story was considered wildly improbable; it may have been that fact that made it popular. But there are armies of Trilbies on this earth, all with a talent. We cannot give them what they have not, but we can often hand them the key to the Powers Within.
This is along educational lines. Yet there are several phases of educational work that I wish to take up later with you even more wonderful than this.
I now take my second subject and say to him: "You are a lazy boy. When boys get lazy they should be taken to the river and thrown in. But if you will work I will be more lenient with you. You do not do the work for your mother that you should do. You do not carry in wood and water for her. Instead of that you lay around stores and in indecent places and smoke cigarettes. Now I am going to make you feel very sick if you ever get hold of another cigarette and smoke it. You will be sick for a day. Your stomach will not hold any food and you will want to have me come and relieve you. If you send for me I will help you".
It may be an hour or two before he smokes. As soon as he does smoke - if he is the right kind of subject - he will be very sick. He will go home and when it seems to him that he will never be cured he sends for me. When I come I again put him to sleep and instil in his sleep-mind the disgust for cigarettes that he would l>c better to possess, and, by gradual steps. I bring him to that point where he is useful to his mother and an honor to the neighborhood.
But there are many boys that cannot be reached in this way. When we see that we cannot use hypnotism generally for the correction of vice, it is our duty to look at the principles that underlie hypnotism. Here we find it approaching a science closer than it does at any other point. We find that certain conditions of the mind are necessary. We learn that we can correct bad habits often when we have only the conscious mind to work on. We find that the power of Suggestion is one of the principle causes of bringing about or curing habits. Then it becomes our duty to study the principles of suggestion. We find that environment, associates, occupation, etc., will all tend to mold one's character. There are exceptions. Some men could be born in the slums and still rise on the summit whole and clean. Others could be born among the most moral surroundings and yet die on the gallows, slayers of their kind!
