Therefore we intend to ask, first, what, if anything, can be ascertained as to the nature of the 'visions' and hallucinations which, according to Mr. Tylor in his celebrated work 'Primitive Culture,' lent their aid to the formation of the idea of 'spirit.'

Their arguments have misled even so eminent a specialist as Professor E.B. Tylor into declaring (Anthropology, 427) that "infanticide comes from hardness of life rather than from hardness of heart."

The ideas of Mr. Tylor on the causes of the origin of religion are now criticised, not from the point of view of spiritualism, but of experimental psychology.
