faith. The exercise of reason alone shows us the true limits of our intellectual faculties. Ignorance of this is the cause of all reveries in science, as in religion; it is only superstition that incites men to launch beyond their conceptions. You accuse of infidelity all those who commit crimes against society. When we answer, that the Jewish and Christian religions have deluged the world with blood, you reply, that it is not as being Jews and Christians, but because they were wicked. At the same time, I hope you allow, that the Spartans, the Athenians, the Romans, the Chinese, did not commit half the atrocities which disgrace Jewish history, the aera of the crusades and the Christian persecutions, of the invasion of America, the massacres of heretics, &c. The candid observer must therefore conclude, that right and wrong is not confined to sects; that the Christian religion, whatever its precepts may be, has not been able to prevent crimes, while nations who knew not so much as the name of Moses or Christ, produced a Confucius, an Aristides, a Socrates, an Epaminondas, a Cincinnatus. Among these nations, who knew not the Lord Jehovah, we find Archimedes, Epicurus, Demosthenes, Plato, Aristotle, Cicero, while the chosen people of God, and their successors, the Christians, borrowed their language, the very names of their gods, and the little science they knew, from these despised infidels. It was not the oracle of Delphos, the augurs, or the sybils, that enlightened the Greeks and Romans. The rabble credited them, as the ignorant Jews and Christians did their prophets and apostles. In short, morals cannot be invented; there cannot be two systems of morality. The precepts must be directed to principles existing in the heart of man. Ignorance conceals from nations the rule of conduct, in the same manner that it prevents them from knowing geometry; the moment they study either, they are put in the road of truth. No wonder, then, that in the times of the greatest oppression, when frightened into certain doctrines by the stories of nurses and parents, many learned men should not have been able to conquer their first prejudices. You certainly know the time when astrology and the philosopher's stone were in fashion; the believers in these reveries were men of science. Van Helmont, Stahl, Boyle, and innumerable others were possessed of this madness. You can be no stranger to the numerous wretches that suffered for witchcraft and necromancy, and, upon the very brink of death, confessed they were guilty.
