Social evolutionist conceptions

Tylor's definition of animism was part of a growing international debate on the nature of " primitive society " by lawyers, theologians, and philologists. The debate defined the field of research of a new science: anthropology. By the end of the 19th century, an orthodoxy on "primitive society" had emerged, but few anthropologists still would accept that definition. The "19th-century armchair anthropologists" argued that "primitive society" (an evolutionary category) was ordered by kinship and divided into exogamous descent groups related by a series of marriage exchanges. Their religion was animism, the belief that natural species and objects had souls.

With the development of private property, the descent groups were displaced by the emergence of the territorial state. These rituals and beliefs eventually evolved over time into the vast array of "developed" religions. According to Tylor, as society became more scientifically advanced, fewer members of that society would believe in animism. However, any remnant ideologies of souls or spirits, to Tylor, represented "survivals" of the original animism of early humanity.

The term clearly began as an expression of a nest of insulting approaches to indigenous peoples and the earliest putatively religious humans. It was and sometimes remains, a colonialist slur.
