One way is to walk by the light within--by the flame that illumines the brain, verifying all by the senses--by touch and sight and sound. The other way is to extinguish the sacred light and follow blindly the steps of another. One way is to be an honest man, giving to others your thought, standing erect, intrepid, careless of phantoms and hells. The other way is to cringe and crawl, to betray your nobler self, and to deprive others of the liberty that you have not the courage to enjoy. Do not imagine that I hate the ones who have taken the wrong side and traveled the wrong road. Our fathers did the best they could. They believed in the Supernatural, and they thought that sacrifices and prayer, fasting and weeping, would induce the Supernatural to give them sunshine, rain and harvest--long life in this world and eternal joy in another. To them, God was an absolute monarch, quick to take offence, sudden in anger, terrible in punishment, jealous, hateful to his enemies, generous to his favorites. They believed also in the existence of an evil God, almost the equal of the other God in strength, and a little superior in cunning. Between these two Gods was the soul of man like a mouse between two paws. Both of these Gods inspired fear. Our fathers did not quite love God, nor quite hate the Devil, but they were afraid of both. They really wished to enjoy themselves with God in the next world and with the Devil in this. They believed that the course of Nature was affected by their conduct; that floods and storms, diseases, earthquakes and tempests were sent as punishments, and that all good phenomena were rewards. Everything was under the direction and control of supernatural powers. The air, the darkness, were filled with angels and devils; witches and wizards planned and plotted against the pious--against the true believers. Eclipses were produced by the sins of the people, and the unusual was regarded as the miraculous. In the good old times Christendom was an insane asylum, and insane priests and prelates were the keepers. There was no science. The people did not investigate--did not think. They trembled and believed. Ignorance and superstition ruled the Christian world. At last a few began to observe, to make records, and to think. It was found that eclipses came at certain intervals, and that their coming could be foretold. This demonstrated that the actions of men had nothing to do with eclipses. A few began to suspect that earthquakes and storms had natural causes, and happened without the slightest reference to mankind.
