Fortunately, minds can be changed. It is easier to make over an unhealthy complex than to make over a weak heart, to straighten out a warped idea than to straighten a bent back. Remarkable indeed have been some of the transformations in people who are supposed to have passed the plastic period in life. While it is true that some persons become "set" in middle life, and almost impervious to new ideas, it is also true that a person at fifty has more richness of experience upon which to draw, more appreciation of the value of the good, than has a person at twenty. If he really wants to change himself, he can do wonderful things by re-education. The first step in this re-education is a grasp of the facts. If you want to pull yourself out of a nervous disorder, first of all learn as much as you can about the causes of "nerves," about the general laws of mind and body, and about your own mental quirks. If this is not sufficient, go to a specialist trained in psychotherapy and let him help you uncover those trouble-making parts of your personality which you cannot find for yourself. It is the purpose of this book to summarize the facts which most need to be known. Let us now consider those methods which the psychopathologist finds most useful in helping his patients to self-knowledge and readjustment. =Various Methods.= As there are a number of schools of medicine, so there are a number of distinct methods of psychotherapy, each with its own theories and methods of procedure, and each with its ardent supporters. These methods may be classified into two groups. The first group includes those methods, hypnosis and psycho-analysis, which make a thorough search through the subconscious mind for the buried complexes causing the trouble, and might, therefore, be called "re-education with subconscious exploration." The other group, includes so-called explanation and suggestion, or methods of "re-education without subconscious exploration," which content themselves with making a general survey and building up new complexes without going to the trouble of uncovering the buried past. Although the theory and the technique vary greatly, the aim of all these methods is the same,--the readjustment of the individual to life. RE-EDUCATION WITH SUBCONSCIOUS EXPLORATION
