Animatism is a term R. R. Marett created to refer to the belief of certain cultures in supernatual forces and powers. Unlike animism, these forces are inanimate and impersonal. For example. the Melanesians, believe in mana as a force inherent in all objects. It is not physical per se, but may manifest itself physically. So, in their system of belief, a warrior who performs bravely in battle does so because of a mana-containing amulet he wears, and not because of his prowess.
