" . . . In all such obsessive neurotics the transformed reproaches which have escaped repressions are always connected with some pleasurably accomplished sexual act of childhood but may be almost entirely lost. The obsessive acts really represent the conflict between impulses of opposite instincts, love and hate, which are usually of equal value. The warring conflict engendered makes for a curiosity to discover the meaning of life forces (sexual largely) and the desire to know the end thereof. The nuclear-complex of all this is a precociousness of emotional life and an intensive fixation on one or the other parent or brother or sister. The intensive love fixation waxes the stronger as the unconscious hate requires increased barriers against its breaking through into the main or everyday personality. As a result of these conflicts the will is partially weakened, there is an incapacity for resolution, first in the realm of love alone; then later succeeds a diffusion or displacement of the mechanism all over the field of activity. A series of secondary defense mechanisms are now brought in and these may enable the obsessive person to get square in a limited way (as religious practices enable many to do). Some special adaptation is required sooner or later, and the individual, having used up all the helps, then falls back upon the different forms of obsessive acts and thinking. Thus the obsessive neurosis is generated." Clark then proceeds to explain: "If one is not permitted to draw deductions from a few data as to the further genesis of the tic disorders, we may still hold out a tentative hypothesis, pieced together from many sources that a certain type of nervous make-up is inherited. In such the emotional life is precocious much beyond the intellectual faculties. The ticquer in infancy has the emotional feelings of love and hate of an adult. Their very precociousness aids the parental fixation and adhesion, and makes it the more difficult for the libido to detach itself at the proper age. One should bear in mind that the parental fixation in itself does not directly produce the mishaps of adult life but this small fault in infancy generates wider and wider maladaptations as development progresses. It is these latter glaring faults and trends that make for the character defects, and these really break down the final effort at adaptations and adjustments producing the tic or obsessive disorder. But the essential nucleus of the defect is lack of balance, precocious parental fixation, and continued attachment to the parent-stem, that makes the adult defect possible. The very infantile precociousness of the emotions argues for the hereditary transmission of destructive temperamental qualities. Here, as elsewhere in tracing hereditariness in so-called functional nervosities, one should take as the unit character for study the mental traits or trends and exclude definite disease entities applied to ancestral disorders. I believe it is not too
