Writing to Dr. Price concerning his anti-slavery pamphlet, Jefferson said:

Southward of the Chesapeake, your pamphlet (against slavery) will find but few readers concurring with it in sentiment on the subject of slavery. From the mouth to the head of the Chesapeake, the bulk of the people will approve it in theory, and it will find a respectable minority ready to adopt it in practice; a minority which for weight and worth of character preponderates against the greater number, who have not the courage to divest their families of a property which, however, keeps their conscience unquiet. Northward of the Chesapeake, you may find here and there an opponent to your doctrine, as you may find here and there a robber and murderer; but in no greater number. In that part of America, there being but few slaves, they can easily disencumber themselves of them; and emancipation is put into such a train that in a few years there will be no slaves northward of Maryland. In Maryland, I do not find such a disposition to begin the redress of this enormity as in Virginia. This is the next State to which we may turn our eyes for the interesting spectacle of justice in conflict with avarice and oppression; a conflict wherein the sacred side is gaining daily recruits from the influx into office of young men grown, and growing up. These have sucked in the principles of liberty, as it were, with their mother's milk; and it is to them I look with anxiety to turn the fate of this question. Be not therefore discouraged. What you have written will do a great deal of good.[94]

In his report to Congress of a conference with Count Vergennes, Foreign Minister of France, on commerce, Jefferson wrote:

The British army, after ravaging the State of Virginia, had sent off a very great number of slaves to New York. By the seventh article of the treaty of peace, they stipulated not to carry away any of these. Notwithstanding this, it was known, when they were evacuating New York, that they were carrying away the slaves, General Washington made an official demand of Sir Guy Carleton, that he should cease to send them away. He answered, that these people had come to them under promise of the King's protection, and that that promise should be fulfilled in preference to the stipulation in the treaty. The State of Virginia, to which nearly the whole of these slaves belonged, passed a law to forbid the recovery of debts due to British subjects. They declared, at the same time, they would repeal the law, if Congress were of opinion they ought to do it. But, desirous that their citizens should be discharging their debts, they afterwards permitted British creditors to prosecute their suits, and to receive their debts in seven equal and annual payments for reimbursement.[95]

Jefferson's letter here to M. de Meunier on the passage of the Ordinance of 1787 shows how he either shifted from his position of regarding emancipation a serious problem to that of agitating against slavery or that he varied his correspondence to suit the person addressed.

There were ten States present; six voted unanimously for it, three against it, and one was divided; and seven votes being requisite to decide the proposition affirmatively, it was lost. The voice of a single individual of the State which was divided, or of one of those which were of the negative, would have prevented this abominable crime from spreading itself over the new country. Thus we see the fate of millions unborn hanging on the tongue of one man, and heaven was silent in that awful moment! But it is to be hoped it will not always be silent, and that the friends to the rights of human nature will in the end prevail.

What a stupendous, what an incomprehensible machine is man! who can endure toil, famine, stripes, imprisonment, and death itself, in vindication of his own liberty, and, the next moment, be deaf to all those motives whose power supported him through his trial, and inflict on his fellow men a bondage, one hour of which is fraught with more misery than ages of that which he rose in rebellion to oppose.[96]

He seemed to regard it later as a problem to be solved only by miraculous methods.

We must await with patience the workings of an overruling Providence, and hope that that is preparing the deliverance of these, our suffering brethren. When the measure of their tears shall be full, when their groans shall have involved heaven itself in darkness, doubtless a God of justice will awaken to their distress, and by diffusing light and liberality among their oppressors, or, at length, by His exterminating thunder, manifest His attention to the things of this world, and that they are not left to the guidance of a blind fatality.[97]

Jefferson, however, seemed to have a kind feeling for the bondmen, as these extracts will show.

I observe in your letter ... that the profits of the whole estate (of Monticello) would be no more than the hire of the few negroes hired out would amount to. Would it be better to hire more where good masters could be got? Would it be better to hire plantations and all, if proper assurance can be provided for the good usage, of everything?[98]

I am miserable till I shall owe not a shilling. The moment that shall be the case, I shall feel myself at liberty to do something for the comfort of the slaves.[99]

The check on the tenants against abusing my slaves was, by the former lease, that I might discontinue it on a reference to arbitrators. Would it not be well to retain an optional right to sue them for ill-usage of the slaves or to discontinue it by arbitration, whichever you should choose at the time?[100]

As far as I can judge from the experiments which have been made to give liberty to, or rather, to abandon persons whose habits have been formed in slavery is like abandoning children.[101]

I am decided on my final return to America to try this experiment. I shall endeavor to import as many Germans as I have grown slaves. I will settle them and my slaves, on farms of fifty acres each, intermingled, and place all on the footing of the Metayers (Medietaini) of Europe. Their children shall be brought up, as others are, in habits of property and foresight, and I have no doubt but that they will be good citizens. Some of their fathers will be so; others I suppose will need government. With these all that can be done is to oblige them to labor as the laboring poor of Europe do, and to apply to their comfortable subsistence the produce of their labor, retaining such a moderate portion of it as may be a just equivalent for the use of the lands they labor, and the stocks and other necessary advances.[102]

The inculcation (in your book) on the master of the moral duties which he owes to the slave, in return for the benefits of his service, that is to say, of food, clothing, care in sickness, and maintenance under age and disability, so as to make him in fact as comfortable and more secure than the laboring man in most parts of the world, ... gives great merit to the work, and will, I have no doubt, produce wholesome impressions.[103]

In the first or second session of the Legislature after I became a member, I drew to this subject the attention of Colonel Bland, one of the oldest, ablest, and most respected members, and he undertook to move for certain moderate extensions of the protection of the laws to these people. I seconded his motion and, as a young member, was more spared in the debate; but he was denounced as an enemy of his country, and was treated with the grossest indecorum.[104]

My opinion has ever been that, until more can be done for them, we should endeavor, with those whom fortune has thrown on our hands, to feed and clothe them well, protect them from ill usage, require such reasonable labor only as is performed voluntarily by freemen, and be led by no repugnances to abdicate them, and our duties to them. The laws do not permit us to turn them loose, if that were for their good; and to commute them for other property is to commit them to those whose usage of them we cannot control.[105]
