87:4.6

Evolutionary religion has, however, paid a terrible price for the concept of dual spiritism. Man’s early philosophy was able to reconcile spirit constancy with the vicissitudes of temporal fortune only by postulating two kinds of spirits, one good and the other bad. And while this belief did enable man to reconcile the variables of chance with a concept of unchanging supermortal forces, this doctrine has ever since made it difficult for religionists to conceive of cosmic unity. The gods of evolutionary religion have generally been opposed by the forces of darkness.
