With a zeal amounting to enthusiasm, with a courage that was heroic, with an energy that never flagged, a determination that brooked no opposition, with a firmness that defied torture and death, this sublime band of reformers sprang to the attack. Stronghold after stronghold was carried, and in a few short but terrible years, the banner of the Reformation waved in triumph over the bloody ensign of Saint Peter. The soul roused from the slumbers of a thousand years began to think. When slaves begin to reason, slavery begins to die. The invention of powder had released millions from the army, and left them to prosecute the arts of peace. Industry began to be remunerative and respectable. Science began to unfold the wings that will finally fill the heavens. Descartes announced to the world the sublime truth that the Universe is governed by law. Commerce began to unfold her wings. People of different countries began to get acquainted. Christians found that Mohammedan gold was not the less valuable on account of the doctrines of its owners. Telescopes began to be pointed toward the stars. The Universe was getting immense. The Earth was growing small. It was discovered that a man could be healthy without being a Catholic. Innumerable agencies were at work dispelling darkness and creating light. The supernatural began to be abandoned, and mankind endeavored to account for all physical phenomena by physical laws. The light of reason was irradiating the world, and from that light, as from the approach of the sun, the ghosts and spectres of superstition wrapped their sheets around their attenuated bodies and vanished into thin air. Other inventions rapidly followed. The wonderful power of steam was made known to the world by Watts and by Fulton. Neptune was frightened from the sea. The locomotive was given to mankind by Stephenson; the telegraph by Franklin and Morse. The rush of the ship, the scream of the locomotive, and the electric flash have frightened the monsters of ignorance from the world, and have left nothing above us but the heaven's eternal blue, filled with glittering planets wheeling through immensity in accordance with _Law_. True religion is a subordination of the passions and interests to the perceptions of the intellect. But when religion was considered the end of life instead of a means of happiness, it overshadowed all other interests and became the destroyer of mankind. It became a hydra-headed monster--a serpent reaching in terrible coils from the heavens and thrusting its thousand fangs into the bleeding, quivering hearts of men. SLAVERY. I HAVE endeavored thus far to show you some of the results produced by enslaving the human mind. I now call your attention to another terrible phase of this subject; the enslavement of the body. Slavery is a very ancient institution, yes, about as ancient as robbery, theft and murder, and is based upon them all.
