ABSTRACT
Riddance of enemies and defending life provide a deep sense of satisfaction. It is a supreme good to risk one’s own life in the line of duty for the just cause of self-defense. Freud visualized aggression as channeled to a variety of illnesses, depending on defenses. For instance, projection led to paranoid aggression. Sup-pressed aggression contributed to higher heart rates, diastolic blood pressures, and hyperadrenegic reactivity. The DSM does not apportion diagnoses to rage and hatred as it does to emotions of depression and anxiety, though anger is implied in antisocial, paranoid/aggressive, and borderline personalities. In addition to external aggression, humans are peculiar in having evolved the emotions disgust and revulsion. They accompany riddance of internal poisons through excreta such as vomit, but they may also be felt toward human invaders who in turn may be associated with their body wastes.
