Note 22 — Chapter I
Reading edition
Tylor supposes animism to have arisen from "two groups of biological problems present to the mind of early man:
"(1) What is it makes the difference between a living body and a dead one, what causes waking, sleep, trance, disease, and death?
"(2) What are those human shapes which appear in dreams and visions?" (Primitive Culture, vol. i, p. 428.)
