Evocation is the act of calling or summoning a spirit, demon, god or other supernatural agent, in the Western mystery tradition. Comparable practices exist in many religions and magical traditions and may employ the use of pharmakeia with and without uttered word formulas.
The Latin word evocatio was the "calling forth" or "summoning away" of a city's tutelary deity. The ritual was conducted in a military setting either as a threat during a siege or as a result of surrender, and aimed at diverting the god's favor from the opposing city to the Roman side, customarily with a promise of better-endowed cult or a more lavish temple. Evocatio was thus a kind of ritual dodge to mitigate looting of sacred objects or images from shrines that would otherwise be sacrilegious or impious.
Human behavior refers to the range of behaviors exhibited by humans and which are influenced by culture, attitudes, emotions, values, ethics, authority, rapport, hypnosis, persuasion, coercion and/or genetics.
The behavior of people (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some outside acceptable limits. In sociology, behavior in general is characterised as having no meaning, being not directed at other people, and thus is the most basic human action. Behavior in this general sense should not be mistaken with social behavior, which is a more advanced action, as social behavior is behavior specifically directed at other people. The acceptability of behavior depends heavily upon social norms and is regulated by various means of social control. Human behavior is studied by the specialised academic disciplines of psychiatry, psychology, social work, sociology, economics, and anthropology.
