The last fear states or _Ultimate Fear States_ which stand out clearly and distinctly in the patient’s mind become the leading, the dominant abnormal, pathological states. The patient thinks that they are the real source of all his troubles, and if they were removed he would be cured. As a matter of fact the ultimate states are not _causes_, but _occasions. The real causes of the psychopathic constitution are the exaggerated impulse of self-preservation and the intensified fear instinct._ XI. _The Principle of Dynamogenesis_ Recessive, and especially dissociated systems, being dormant subconsciously, may become envigorated, may accumulate emotion, and when the opportunity comes, may react to external stimuli with vigor and energy. The attacks may occur like epileptic fits. They often so well simulate epileptic maladies that even good clinicians have classed such attacks under the term of larval epilepsy, psychic epilepsy, hystero-epilepsy, or psychic equivalent of epilepsy. This subconscious energy manifestation may be termed _Dynamogenesis_. XII. _The Principle of Inhibition_ Self-preservation and the fear instinct inhibit associated mental systems, producing morbid states. _Morbid mental states, however, are not produced by inhibitions, or repressions._ It is only when the inhibitive factors are self and fear that a true morbid mental state, or neurosis arises. To regard self repression as a bad condition and leading to diseases is to misapprehend the nature of man, to falsify psychology, and to misrepresent the development of humanity. The self should not become hypertrophied. Self-preservation should not become overgrown. The self must be kept within limits. The self impulse should be kept under control by the individual. For true happiness is to be a law unto oneself. As the great Greek thinkers put it: Happiness is in self rule. The unruly are miserable. In fact, self-control is absolutely requisite to mental health, to sanity. _Self-repression is requisite for happiness. Self-repression never leads to disease._ It is only when self-repression is produced and dominated by selfishness and fear that morbid states of a psychopathic, neurotic character are sure to arise. It is not inhibitions that produce fear, but _it is fear that produces inhibitions_. To ascribe neurosis to self-repression and to conflict is like attributing malaria or tuberculosis to air and light. XIII. _The Principle of Mental Contest and Discord_
