The author is neither a professional scientist nor an academic philosopher nor a theoretical theologian. He does not claim to have had the highly specialized training which would really fit him to write authoritatively upon the subjects pertaining to such men. Therefore in entering their domains he feels himself to be an intruder, whom they will necessarily treat with scorn and contempt. He does claim, however, that what books and dons have not taught him, life has taught. Through intense and wide living and deep reflection thereon, he has come to the perception of a true science, to the recognition of a true philosophy, and to the realization of a true theology. No don and no book can go farther than that, farther than TRUTH. The fashionable theories of our time have their entrances and make their exits, but there is an enduring Truth which outlives all change. Hence what is set down here through inward vision and uncommon experience bears its own authority and will convey its own trustworthiness to whomsoever is ripe to receive it.
