Religion has not civilized man—man has civilized religion. God improves as man advances.
Let me call your attention to what we have received from the followers of the ghosts. Let me give you an outline of the sciences as taught by these philosophers of the clouds.
All diseases were produced, either as a punishment by the good ghosts, or out of pure malignity by the bad ones. There were, properly speaking, no diseases. The sick were possessed by ghosts. The science of medicine consisted in knowing how to persuade these ghosts to vacate the premises. For thousands of years the diseased were treated with incantations, with hideous noises, with drums and gongs. Everything was done to make the visit of the ghost as unpleasant as possible, and they generally succeeded in making things so disagreeable that if the ghost did not leave, the patient did. These ghosts were supposed to be of different rank, power and dignity. Now and then a man pretended to have won the favor of some powerful ghost, and that gave him power over the little ones. Such a man became an eminent physician.
It was found that certain kinds of smoke, such as that produced by burning the liver of a fish, the dried skin of a serpent, the eyes of a toad, or the tongue of an adder, were exceedingly offensive to the nostrils of an ordinary ghost. With this smoke, the sick room would be filled until the ghost vanished or the patient died.
It was also believed that certain words,—the names of the most powerful ghosts,—when properly pronounced, were very effective weapons. It was for a long time thought that Latin words were the best,—Latin being a dead language, and known by the clergy. Others thought that two sticks laid across each other and held before the wicked ghost would cause it instantly to flee in dread away.
For thousands of years, the practice of medicine consisted in driving these evil spirits out of the bodies of men.
In some instances, bargains and compromises were made with the ghosts. One case is given where a multitude of devils traded a man for a herd of swine. In this transaction the devils were the losers, as the swine immediately drowned themselves in the sea. This idea of disease appears to have been almost universal, and is by no means yet extinct.
The contortions of the epileptic, the strange twitchings of those afflicted with chorea, the shakings of palsy, dreams, trances, and the numberless frightful phenomena produced by diseases of the nerves, were all seized upon as so many proofs that the bodies of men were filled with unclean and malignant ghosts.
Whoever endeavored to account for these things by natural causes, whoever attempted to cure diseases by natural means, was denounced by the church as an infidel. To explain anything was a crime. It was to the interest of the priest that all phenomena should be accounted for by the will and power of gods and devils. The moment it is admitted that all phenomena are within the domain of the natural, the necessity for a priest has disappeared. Religion breathes the air of the supernatural. Take from the mind of man the idea of the supernatural, and religion ceases to exist. For this, reason, the church has always despised the man who explained the wonderful. Upon this principle, nothing was left undone to stay the science of medicine. As long as plagues and pestilences could be stopped by prayer, the priest was useful. The moment the physician found a cure, the priest became an extravagance. The moment it began to be apparent that prayer could do nothing for the body, the priest shifted his ground and began praying for the soul.
Long after the devil idea was substantially abandoned in the practice of medicine, and when it was admitted that God had nothing to do with ordinary coughs and colds, it was still believed that all the frightful diseases were sent by him as punishments for the wickedness of the people. It was thought to be a kind of blasphemy to even try, by any natural means, to stay the ravages of pestilence. Formerly, during the prevalence of plague and epidemics, the arrogance of the priest was boundless. He told the people that they had slighted the clergy, that they had refused to pay tithes, that they had doubted some of the doctrines of the church, and that God was now taking his revenge. The people for the most part, believed this infamous tissue of priestcraft. They hastened to fall upon their knees; they poured out their wealth upon the altars of hypocrisy; they abased and debased themselves; from their minds they banished all doubts, and made haste to crawl in the very dust of humility.
