"We are in respect to our possible higher evolution much in the position of the original Ape of the Darwinian theory"
"It would have been impossible for that Ape leading his instinctive arboreal life in primeval forests to conceive that there would be one day an animal on the earth who would use a new faculty called reason upon the materials of his inner and outer existence, who would dominate by that power his instincts and habits, change the circumstances of his physical life, build for himself houses of stone, manipulate Nature's forces, sail the seas, ride the air, develop codes of conduct, evolve conscious methods for his mental and spiritual development.
Man, because he has acquired reason and still more because he has indulged his power of imagination and intuition, is able to conceive an existence higher than his own and even to envisage his personal elevation beyond his present state into that existence. His idea of the supreme state is an absolute of all that is positive to his own concepts and desirable to his own instinctive aspiration... It is so that he conceives his gods; it is so that he constructs his heavens. But it is not so that his reason conceives of the possible earth and a possible humanity. His dream of God and Heaven is really a dream of his own perfection; but he finds the same difficulty in accepting its practical realisation here for his ultimate aim as would the ancestral Ape if called upon to believe in himself as the future Man."
