Man has found that he must give liberty to others in order to have it himself. He has found that a master is also a slave;—that a tyrant is himself a serf. He has found that governments should be founded and administered by man and for man; that the rights of all are equal; that the powers that be are not ordained by God; that woman is at least the equal of man; that men existed before books; that religion is one of the phases of thought through which the world is passing; that all creeds were made by man; that everything is natural; that a miracle is an impossibility; that we know nothing of origin and destiny; that concerning the unknown we are all equally ignorant; that the pew has the right to contradict what the pulpit asserts; that man is responsible only to himself and those he injures, and that all have a right to think.
True religion must be free. Without perfect liberty of the mind there can be no true religion. Without liberty the brain is a dungeon—the mind a convict. The slave may bow and cringe and crawl, but he cannot adore—he cannot love.
True religion is the perfume of a free and grateful heart. True religion is a subordination of the passions to the perceptions of the intellect. True religion is not a theory—it is a practice. It is not a creed—it is a life.
A theory that is afraid of investigation is undeserving a place in the human mind.
I do not pretend to tell what all the truth is. I do not pretend to have fathomed the abyss, nor to have floated on outstretched wings level with the dim heights of thought. I simply plead for freedom. I denounce the cruelties and horrors of slavery. I ask for light and air for the souls of men. I say, take off those chains—break those manacles—free those limbs—release that brain! I plead for the right to think—to reason—to investigate. I ask that the future may be enriched with the honest thoughts of men. I implore every human being to be a soldier in the army of progress.
I will not invade the rights of others. You have no right to erect your toll-gate upon the highways of thought. You have no right to leap from the hedges of superstition and strike down the pioneers of the human race. You have no right to sacrifice the liberties of man upon the altars of ghosts. Believe what you may; preach what you desire; have all the forms and ceremonies you please; exercise your liberty in your own way but extend to all others the same right.
I will not attack your doctrines nor your creeds if they accord liberty to me. If they hold thought to be dangerous—if they aver that doubt is a crime, then I attack them one and all, because they enslave the minds of men.
I attack the monsters, the phantoms of imagination that have ruled the world. I attack slavery. I ask for room—room for the human mind.
Why should we sacrifice a real world that we have, for one we know not of? Why should we enslave ourselves? Why should we forge fetters for our own hands? Why should we be the slaves of phantoms. The darkness of barbarism was the womb of these shadows. In the light of science they cannot cloud the sky forever. They have reddened the hands of man with innocent blood. They made the cradle a curse, and the grave a place of torment.
They blinded the eyes and stopped the ears of the human race. They subverted all ideas of justice by promising infinite rewards for finite virtues, and threatening infinite punishment for finite offenses.
