I sometime ago received a letter from a Mr. M'Gregory of Derby, in your State; it is written with such a degree of good sense and appearance of candor, as entitles it to an answer. Yet the writer being entirely unknown to me, and the stratagems of the times very multifarious, I have thought it best to avail myself of your friendship, and enclose the answer to you. You will see its nature. If you find from the character of the person to whom it is addressed, that no improper use would probably be made of it, be so good as to seal and send it. Otherwise suppress it. How will the vote of your State and Rhode Island be as to A. and P.? I am, with great and sincere esteem, dear Sir, your friend and servant. TO URIAH M'GREGORY. MONTICELLO, August 13, 1800. SIR,--Your favor of July the 19th has been received, and received with the tribute of respect due to a person, who, unurged by motives of personal friendship or acquaintance, and unaided by particular information, will so far exercise his justice as to advert to the proofs of approbation given a public character by his own State and by the United States, and weigh them in the scale against the fatherless calumnies he hears uttered against him. These public acts are known even to those who know nothing of my private life, and surely are better evidence to a mind disposed to truth, than slanders which no man will affirm on his own knowledge, or ever saw one who would. From the moment that a portion of my fellow citizens looked towards me with a view to one of their highest offices, the floodgates of calumny have been opened upon me; not where I am personally known, where their slanders would be instantly judged and suppressed, from a general sense of their falsehood; but in the remote parts of the Union, where the means of detection are not at hand, and the trouble of an inquiry is greater than would suit the hearers to undertake. I know that I might have filled the courts of the United States with actions for these slanders, and have ruined perhaps many persons who are not innocent. But this would be no equivalent to the loss of character. I leave them, therefore, to the reproof of their own consciences. If these do not condemn them, there will yet come a day when the false witness will meet a judge who has not slept over his slanders. If the reverend Cotton Mather Smith of Shena believed this as firmly as I do, he would surely never have affirmed that "I had obtained my property by fraud and robbery; that in one instance, I had defrauded and robbed a widow and fatherless children of an estate to which I was executor, of ten thousand pounds sterling, by keeping the property and paying them in money at the nominal rate, when it was worth no more than forty for one; and that all this could be proved." Every tittle of it is fable; there not having existed a single circumstance of my life to which any part of it can hang.
