Natural impulses of anger, hostility, and territoriality (守卫地盘的天性) are expressed through acts of violence. These are all qualities that humans share with animals. Aggression is a kind of innate (天生的) survival mechanism, an instinct for self-preservation, that allows animals to defend themselves from threats to their existence. But, on the other hand, human violence shows evidence of being a learned behavior. In the case of human aggression, violence cannot be simply reduced to an instinct. The many expressions of human violence are always conditioned by social conventions that give shape to aggressive behavior.
