"American citizens are instrumental in carrying on a traffic in enslaved Africans, equally in violation of the laws of humanity and in defiance of those of their own country. The same just and benevolent motives which produced interdiction in force against the criminal conduct will doubtless be felt by Congress in devising further means of suppressing the evil."

“Conscience is the most sacred of all property; other property depending in part on positive law, the exercise of that being a natural and unalienable right. To guard a man's house as his castle, to pay public and enforce private debts with the most exact faith, can give no title to invade a man's conscience, which is more sacred than his castle, or to withhold from it that debt of protection for which the public faith is pledged by the very nature and original conditions of the social pact.”

“Some degree of abuse is inseparable from the proper use of every thing; and in no instance is this more true than in that of the press. It has accordingly been decided, by the practice of the states, that it is better to leave a few of its noxious branches to their luxuriant growth, than, by pruning them away, to injure the vigor of those yielding the proper fruits. And can the wisdom of this policy be doubted by any one who reflects that to the press alone, checkered as it is with abuses, the world is indebted for all the triumphs which have been gained by reason and humanity over error and oppression?”

“Another of my wishes is to depend as little as possible on the labor of slaves.”

“This Assembly doth explicitly and peremptorily declare, that it views the powers of the federal government, as resulting from the compact, to which the states are parties, as limited by the plain sense and intention of the instrument constituting the compact; as no further valid than they are authorized by the grants enumerated in that compact; and that in case of deliberate, palpable, and dangerous exercise of other powers, not granted by the said compact, the states who are parties thereto, have the right, and are in duty bound, to interpose, for arresting the progress of the evil, and for maintaining within their respective limits, the authorities, rights and liberties appertaining to them.”

“Of all the enemies to public liberty war is, perhaps, the most to be dreaded, because it comprises and develops the germ of every other. War is the parent of armies; from these proceed debts and taxes; and armies, and debts, and taxes are the known instruments for bringing the many under the domination of the few. In war, too, the discretionary power of the Executive is extended; its influence in dealing out offices, honors, and emoluments is multiplied; and all the means of seducing the minds, are added to those of subduing the force, of the people. The same malignant aspect in republicanism may be traced in the inequality of fortunes, and the opportunities of fraud, growing out of a state of war, and in the degeneracy of manners and of morals engendered by both. No nation could preserve its freedom in the midst of continual warfare.”

“Since the general civilization of mankind, I believe there are more instances of the abridgment of the freedom of the people by gradual and silent encroachments of those in power, than by violent and sudden usurpations; but, on a candid examination of history, we shall find that turbulence, violence, and abuse of power, by the majority trampling on the rights of the minority, have produced factions and commotions, which, in republics, have, more frequently than any other cause, produced despotism. If we go over the whole history of ancient and modern republics, we shall find their destruction to have generally resulted from those causes.”
