“I readily agree with you that there are numbers of enthusiasts who will set up the cry against me, but at the same time I do insist that I shall have as many sensible readers who will make use of their reason. “I hear that the Parliament of Toulouse and some other courts of justice have a method of proceeding peculiar to themselves. They admit fourths, thirds, and sixths of a proof; so that with six hearsays on one side, three on the other, and four-fourths of a presumption, they frame three complete proofs; and in consequence of this curious demonstration will condemn you a man to be broken upon the wheel without mercy. Now, the least acquaintance with the art of logic or reasoning would point out a different method of proceeding to them. What we call a half proof can never amount to more than a suspicion; but there is no such thing in reality as a half proof; for a thing must either be proved or not proved; there is no medium. “A million of suspicions put together can no more frame a regular proof than a million of ciphers can compose an arithmetical number. “There are fourths of tones or sounds in music, and these are to be expressed; but there are no fourths in truths, nor in reasoning. “Two witnesses agreeing in the same deposition, are esteemed to make a proof; but this is not enough; these two witnesses should be clear of all passion and prejudice, and, above all, their testimony should be in every part consonant with reason. “Suppose four persons of the most respectable appearance were to come and swear in a court of justice that they saw an infirm old man take a vigorous young fellow by the collar and toss him out of a window, to the distance of six or seven feet; certainly such deponents ought to be sent to a madhouse. “But the eight judges of Toulouse condemned John Calas upon a much more improbable accusation; for there was no one appeared to swear that he had actually seen this feeble old man of seventy seize a stout young fellow of twenty-eight, and hang him up. Indeed, certain enthusiastic wretches said that they had been told by other enthusiasts like themselves that they had been told by some of their own sect that they had heard that John Calas had by a supernatural strength overcome his son and hanged him. And thus was the most absurd of all sentences passed upon the most absurd of all evidence. “In fine, there is no remedy against such kind of proceedings but that those who purchase their seats in a court of justice should, for the future, be obliged to study a little better.” This treatise on toleration is a petition which humanity with all submission presents to power and prudence. I have sowed a grain that may perhaps produce a rich harvest. We may hope everything from time, from the goodness of the heart of our gracious monarch, the wisdom of his ministers, and the spirit of sound reason, which begins to diffuse its salutary influence over all minds.
