Fear, rage and love reactions develop first in association with the suckling reflex, and the accompaniments, the mother's smile and voice, the color of her hair, eyes and skin, her breasts and odors. Each time the babe reacts to a pleasant or unpleasant stimulus, there is an outpouring of certain internal secretions, a cessation of others, a tingling of certain vegetative nerves and organs, a hushing of others. The ensemble of reactions tends to be repeated around the same stimulus, until the whole becomes automatic. One may observe the same process in the lower animals. Offer a piece of meat to a dog and his mouth waters. Ring a bell before offering the meat. Repeat this a number of times, and after a while the mere ringing of the bell, without the presence of the meat, will cause his mouth to water. This associated vegetative secretion reflex is the most fundamental to grasp in an understanding of the deepest strata of personality. Now there are, besides the associated vegetative-endocrine reactions, certain inborn automatic processes in the vegetative system and in the internal secretion system, which work automatically to produce increased intravisceral pressures. The reduction of these pressures below the point of their intrusion upon consciousness, their relief, as we say, also form the centers of constellations around feelings of satisfaction or love. Such, for example, are the voiding of excretions. Sooner or later, these automatic reactions, and the associated reflexes formed around the mother, father and other associates, come into conflict. Inhibitions or prohibitions of the automatic act at certain times or moments are imposed by somebody. And so there occurs a pitting of the automatic mechanism against the associated reflex. Conflict with adjustment by suppression must occur. Thus a sense of self as active wisher (for the automatically pleasant experience), and punishable suppressor (of the same in favor of the acquired associated reflex) develops. So far, so good. Compromise by regulation from above, from the brain, of the automatic reactions follows, as training. No absolute repression is forced, no absolute encouragement is indorsed. Harmonious equilibrium, or normality, continues. But now there come upon the scene the unconscious fears. In the paleontology of character, these fears are the deepest strata, the eocene era, so to speak, of the soul. They are the hardest to get at and the most silent, as well as the most dominant of the influences which guide conduct. In Sir Walter Raleigh's words: "Passions are best likened to streams and floods. The shallows murmur, the deeps are dumb." During the first period of childhood, up to five or six, the primary fears group themselves around the taboos and secrets of its life.
