Animism is the belief that objects, places, and creatures all possess a distinct spiritual essence. Animism perceives all things—animals, plants, rocks, rivers, weather systems, human handiwork, and in some cases words—as being animated, having agency and free will. Animism is used in anthropology of religion as a term for the belief system of many Indigenous peoples in contrast to the relatively more recent development of organized religions. Animism is a metaphysical belief which focuses on the supernatural universe : specifically, on the concept of the immaterial soul.

In many religious and philosophical traditions, the soul is the non-material essence of a person, which includes one's identity, personality, and memories, an immaterial aspect or essence of a living being that is believed to be able to survive physical death. The concept of the soul is generally applied to humans, though it can also be applied to other living or even non-living entities, as in animism.
