And so there may be a place called "heaven," the home of God, where angels float and fly and play on harps and hear with joy the groans and shrieks of the lost in hell, but of this there is no evidence. It all rests on dreams and visions of the insane. There may be a power superior to nature, a power that governs and directs all things, but the existence of this power has not been established. In the presence of the mysteries of life and thought, of force and substance, of growth and decay, of birth and death, of joy and pain, of the sufferings of the good, the triumphs of wrong, the intelligent honest man is compelled to say: "I do not know." But we do know how gods and devils, heavens and hells, have been made. We know the history of inspired books--the origin of religions. We know how the seeds of superstition were planted and what made them grow. We know that all superstitions, all creeds, all follies and mistakes, all crimes and cruelties, all virtues, vices, hopes and fears, all discoveries and inventions, have been naturally produced. By the light of reason we divide the useful from the hurtful, the false from the true. We know the past--the paths that man has traveled--his mistakes, his triumphs. We know a few facts, a few fragments, and the imagination, the artist of the mind, with these facts, these fragments, rebuilds the past, and on the canvas of the future deftly paints the things to be. We believe in the natural, in the unbroken and unbreakable succession of causes and effects. We deny the existence of the supernatural. We do not believe in any God who can be pleased with incense, with kneeling, with bell-ringing, psalm-singing, bead-counting, fasting or prayer--in any God who can be flattered by words of faith or fear. We believe in the natural. We have no fear of devils, ghosts or hells. We believe that Mahatmas, astral bodies, materializations of spirits, crystal gazing, seeing the future, telepathy, mind reading and Christian Science are only cunning frauds, the genuineness of which is established by the testimony of incompetent, honest witnesses. We believe that Cunning plates fraud with the gold of honesty, and veneers vice with virtue. We know that millions are seeking the impossible--trying to secure the aid of the supernatural--to solve the problem of life--to guess the riddle of destiny, and to pluck from the future its secret. We know that all their efforts are in vain. We believe in the natural. We believe in home and fireside--in wife and child and friend--in the realities of this world. We have faith in facts--in knowledge--in the development of the brain. We throw away superstition and welcome science. We banish the phantoms, the mistakes and lies and cling to the truth. We do not enthrone the unknown and crown our ignorance. We do not stand with our backs to the sun and mistake our shadow for God.
