"the rights of humanity must in all cases be duly and mutually respected"

"... Among the lesser criticisms which have been exercised on the Constitution, it has been remarked that the validity of engagements ought to have been asserted in favor of the United States, as well as against them; and in the spirit which usually characterizes little critics, the omission has been transformed and magnified into a plot against the national rights. The authors of this discovery may be told, what few others need to be informed of, that as engagements are in their nature reciprocal, an assertion of their validity on one side, necessarily involves a validity on the other side; and that as the article is merely declaratory, the establishment of the principle in one case is sufficient for every case. They may be further told, that every constitution must limit its precautions to dangers that are not altogether imaginary; and that no real danger can exist that the government would dare, with, or even without, this constitutional declaration before it, to remit the debts justly due to the public, on the pretext here condemned.

  "8. "To provide for amendments to be ratified by three fourths of the States under two exceptions only."

  "That useful alterations will be suggested by experience, could not but be foreseen. It was requisite, therefore, that a mode for introducing them should be provided. The mode preferred by the convention seems to be stamped with every mark of propriety. It guards equally against that extreme facility, which would render the Constitution too mutable; and that extreme difficulty, which might perpetuate its discovered faults. It, moreover, equally enables the general and the State governments to originate the amendment of errors, as they may be pointed out by the experience on one side, or on the other. The exception in favor of the equality of suffrage in the Senate, was probably meant as a palladium to the residuary sovereignty of the States, implied and secured by that principle of representation in one branch of the legislature; and was probably insisted on by the States particularly attached to that equality. The other exception must have been admitted on the same considerations which produced the privilege defended by it.

  "9. "The ratification of the conventions of nine States shall be sufficient for the establishment of this Constitution between the States, ratifying the same."

  "This article speaks for itself. The express authority of the people alone could give due validity to the Constitution. To have required the unanimous ratification of the thirteen States, would have subjected the essential interests of the whole to the caprice or corruption of a single member. It would have marked a want of foresight in the convention, which our own experience would have rendered inexcusable.

  "Two questions of a very delicate nature present themselves on this occasion: 1. On what principle the Confederation, which stands in the solemn form of a compact among the States, can be superseded without the unanimous consent of the parties to it? 2. What relation is to subsist between the nine or more States ratifying the Constitution, and the remaining few who do not become parties to it?

  "The first question is answered at once by recurring to the absolute necessity of the case; to the great principle of self-preservation; to the transcendent law of nature and of nature's God, which declares that the safety and happiness of society are the objects at which all political institutions aim, and to which all such institutions must be sacrificed. Perhaps, also, an answer may be found without searching beyond the principles of the compact itself. It has been heretofore noted among the defects of the Confederation, that in many of the States it had received no higher sanction than a mere legislative ratification. The principle of reciprocality seems to require that its obligation on the other States should be reduced to the same standard. A compact between independent sovereigns, founded on ordinary acts of legislative authority, can pretend to no higher validity than a league or treaty between the parties. It is an established doctrine on the subject of treaties, that all the articles are mutually conditions of each other; that a breach of any one article is a breach of the whole treaty; and that a breach, committed by either of the parties, absolves the others, and authorizes them, if they please, to pronounce the compact violated and void. Should it unhappily be necessary to appeal to these delicate truths for a justification for dispensing with the consent of particular States to a dissolution of the federal pact, will not the complaining parties find it a difficult task to answer the multiplied and important infractions with which they may be confronted? The time has been when it was incumbent on us all to veil the ideas which this paragraph exhibits. The scene is now changed, and with it the part which the same motives dictate.

  "The second question is not less delicate; and the flattering prospect of its being merely hypothetical forbids an overcurious discussion of it. It is one of those cases which must be left to provide for itself. In general, it may be observed, that although no political relation can subsist between the assenting and dissenting States, yet the moral relations will remain uncancelled. The claims of justice, both on one side and on the other, will be in force, and must be fulfilled; the rights of humanity must in all cases be duly and mutually respected; whilst considerations of a common interest, and, above all, the remembrance of the endearing scenes which are past, and the anticipation of a speedy triumph over the obstacles to reunion, will, it is hoped, not urge in vain moderation on one side, and prudence on the other.
PUBLIUS"----James Madison, The Federalist No. 43, Independent Journal, Wednesday, January 23, 1788.

"The opinion of the Federalist has always been considered as of great authority. It is a complete commentary on our Constitution; and is appealed to by all parties in the questions to which that instrument has given birth. Its intrinsic merit entitles it to this high rank; and the part two of its authors performed in framing the constitution, put it very much in their power to explain the views with which it was framed..."--Chief Justice John Marshall, U.S. Supreme Court, Cohens v. Virginia (1821).

"It is a rule of law that, in order to ascertain the import of a contract, the evident intention of the parties, at the time of forming it, is principally to be regarded. Previous to the formation of this Constitution, there existed certain principles of the law of nature and nations, consecrated by time and experience, in conformity to which the Constitution was formed."-- Mr. Elliot, Debate in U.S. House of Representatives, Oct. 25, 1803 (The Debates in the Several State Conventions on the Adoption of the Federal Constitution), [Elliot's Debates, Volume 4]
