The law was in some of the countries of Europe, that if a man's house was broken into between sunset and sunrise and the owner killed the intruder, it should be considered justifiable homicide. But it was also considered that it was just possible that a man living alone might entice another to his house in the night-time, kill him and then pretend that his victim was a robber. In order to prevent this, it was enacted that when a person was killed by a man living alone and under such circumstances, the solitary householder should not be held innocent unless he produced in court some animal, a dog or a cat, that had been an inmate of the house and had witnessed the death of the person killed. The prisoner was then compelled in the presence of such animal to make a solemn declaration of his innocence, and if the animal failed to contradict him, he was declared guiltless,--the law taking it for granted that the Deity would cause a miraculous manifestation by a dumb animal, rather than allow a murderer to escape. It was the law in England that any one convicted of a crime, could appeal to what was called corsned or morsel of execration. This was a piece of cheese or bread of about an ounce in weight, which was first consecrated with a form of exorcism desiring that the Almighty, if the man were guilty, would cause convulsions and paleness, and that it might stick in his throat, but that it might if the man were innocent, turn to health and nourishment. Godwin, the Earl of Kent, during the reign of Edward the Confessor, appealed to the corsned, which sticking in his throat, produced death. There were also trials by water and by fire. Persons were made to handle red hot iron, and if it burned them their guilt was established; so their hands and feet were tied, and they were thrown into the water, and if they sank they were pronounced guilty and allowed to drown. I give these instances to show you what has happened, and what always will happen, in countries where ignorance prevails, and people abandon the great standard of reason. And also to show to you that scarcely any man, however great, can free himself of the superstitions of his time. Kepler, one of the greatest men of the world, and an astronomer second to none, although he plucked from the stars the secrets of the universe, was an astrologer and thought he could predict the career of any man by finding what star was in the ascendant at his birth. This infinitely foolish stuff was religiously believed by him, merely because he had been raised in an atmosphere of boundless credulity. Tycho Brahe, another astronomer who has been, and is called the prince of astronomers--not only believed in astrology, but actually kept an idiot in his service, whose disconnected and meaningless words he carefully wrote down and then put them together in such a manner as to make prophecies, and then he patiently and confidently awaited their fulfillment.
