Socrates was accustomed to hear a voice which always admonished him when the course he was pursuing or contemplating was wrong or harmful; but it was silent when the contemplated course was right. This was the famous "Dæmon of Socrates," and was described and discussed by Xenophon and Plato as well as other Greek writers and many modern ones. Socrates himself called it the "Divine Sign." And on that account he was accused of introducing new gods, and thus offering indignity to the accredited gods of Greece. On this, as one of the leading charges, Socrates was tried and condemned to death; but in all the proceedings connected with his trial and condemnation he persisted in his course which he knew would end in his death, rather than be false to his convictions of duty and right; and this he did because the voice--the "Divine Sign"--which always before had restrained him in any wrong course, was not heard restraining him in his present course. Only once was it heard, and that was to restrain him from preparing any set argument in his defence before his judges. So he accepted his sentence and drank the hemlock, surrounded by his friends, to whom he calmly explained that death could not be an evil thing, not only from the arguments which he had adduced, but also because the Divine Sign, which never failed to admonish him when pursuing any harmful course, had not admonished nor restrained him in this course which had led directly to his death. Joan of Arc heard voices, which in childhood only guided her in her ordinary duties, but which in her early womanhood made her one of the most conspicuous figures in the history of her time. They placed her, a young and unknown peasant girl, as a commander at the head of the defeated, disorganized, and discouraged armies of France, aroused them to enthusiasm, made them victorious, freed her country from the power of England, and placed the rightful prince upon the throne. She also heard and obeyed her guiding voices, even unto martyrdom.
