The spontaneous intellect of man always defines the divine which it feels in ways that harmonize with its temporary intellectual prepossessions.

Context

“Let me close, then, by briefly enumerating what she can do for religion. If she will abandon metaphysics and deduction for criticism and induction, and frankly transform herself from theology into science of religions, she can make herself enormously useful. The spontaneous intellect of man always defines the divine which it feels in ways that harmonize with its temporary intellectual prepossessions. Philosophy can by comparison eliminate the local and the accidental from these definitions. Both from dogma and from worship she can remove historic incrustations. By confronting the spontaneous religious constructions with the results of natural science, philosophy can also eliminate doctrines that are now known to be scientifically absurd or incongruous.” source
