God had given the knowledge of just and unjust, right and wrong, throughout all the ages which preceded Christianity. God never changed nor can change. The constitution of our souls, our principles of reason and morality, will ever be the same. How is virtue promoted by theological distinctions, by dogmas founded on those distinctions, by persecutions founded on those dogmas? Nature, terrified and horror-struck at all these barbarous inventions, calls aloud to all men: Be just, and not persecuting sophists. You read in the "_Zend-Avesta_," which is the summary of the laws of Zoroaster, this admirable maxim: "When it is doubtful whether the action you are about to perform is just or unjust, abstain from doing it." What legislator ever spoke better? We have not here the system of "probable opinions", invented by people who call themselves "the Society of Jesus". JUSTICE. That "justice" is often extremely unjust, is not an observation merely of the present day; "_summum jus, summa injuria_," is one of the most ancient proverbs in existence. There are many dreadful ways of being unjust; as, for example, that of racking the innocent Calas upon equivocal evidence, and thus incurring the guilt of shedding innocent blood by a too strong reliance on vain presumptions. Another method of being unjust is condemning to execution a man who at most deserves only three months' imprisonment; this species of injustice is that of tyrants, and particularly of fanatics, who always become tyrants whenever they obtain the power of doing mischief. We cannot more completely demonstrate this truth than by the letter of a celebrated barrister, written in 1766, to the marquis of Beccaria, one of the most celebrated professors of jurisprudence, at this time, in Europe: _Letter To The Marquis Of Beccaria, Professor Of Public Law At Milan, On The Subject Of M. De Morangies, 1772._ Sir:--You are a teacher of laws in Italy, a country from which we derive all laws except those which have been transmitted to us by our own absurd and contradictory customs, the remains of that ancient barbarism, the rust of which subsists to this day in one of the most flourishing kingdoms of the earth. Your book upon crimes and punishments opened the eyes of many of the lawyers of Europe who had been brought up in absurd and inhuman usages; and men began everywhere to blush at finding themselves still wearing their ancient dress of savages.
