Suppression is not annihilation. "Psychic" energy is no more capable of being abolished than the forms we recognize as physical. If it is neither exploded nor converted, it is turned inwards, to lead a surreptitious, subterranean life. An isolated or spasmodic manifestation is a sign of immaturity, crudity, savagery; a suppressed activity is the cause of all kinds of intellectual and moral pathology. One form of the resulting pathology constitutes "reaction" in the sense in which the historian speaks of reactions. A conventionally familiar instance is Stuart license after Puritan restraint. A striking modern instance is the orgy of extravagance following upon the enforced economies and hardships of war, the moral let-down after its highstrung exalted idealisms, the deliberate carelessness after an attention too intense and too narrow. Outward manifestation of many normal activities had been suppressed. But activities were not suppressed. They were merely dammed up awaiting their chance. Now such "reactions" are simultaneous as well as successive. Resort to artificial stimulation, to alcoholic excess, sexual debauchery, opium and narcotics are examples. Impulses and interests that are not manifested in the regular course of serviceable activity or in recreation demand and secure a special manifestation. And it is interesting to note that there are two opposite forms. Some phenomena are characteristic of persons engaged in a routine monotonous life of toil attended with fatigue and hardship. And others are found in persons who are intellectual and executive, men whose activities are anything but monotonous, but are narrowed through over-specialization. Such men think too much, that is, too much along a _particular_ line. They carry too heavy responsibilities; that is, their offices of service are not adequately shared with others. They seek relief by escape into a more sociable and easy-going world. The imperative demand for companionship not satisfied in ordinary activity is met by convivial indulgence. The other class has recourse to excess because its members have in ordinary occupations next to no opportunity for imagination. They make a foray into a more highly colored world as a substitute for a normal exercise of invention, planning and judgment. Having no regular responsibilities, they seek to recover an illusion of potency and of social recognition by an artificial exaltation of their submerged and humiliated selves.
