7. Want of sanction to the laws, and of coercion in the Government of the Confederacy.

A sanction is essential to the idea of law, as coercion is to that of Government. The federal system being destitute of both, wants the great vital principles of a Political Cons[ti]tution. Under the form of such a Constitution, it is in fact nothing more than a treaty of amity of commerce and of alliance, between so many independent and Sovereign States. From what cause could so fatal an omission have happened in the articles of Confederation? from a mistaken confidence that the justice, the good faith, the honor, the sound policy, of the several legislative assemblies would render superfluous any appeal to the ordinary motives by which the laws secure the obedience of individuals: a confidence which does honor to the enthusiastic virtue of the compilers, as much as the inexperience of the crisis apologizes for their errors. The time which has since elapsed has had the double effect, of increasing the light, and tempering the warmth, with which the arduous work may be revised. It is no longer doubted that a unanimous and punctual obedience of 13 independent bodies, to the acts of the federal Government, ought not be calculated on. Even during the war, when external danger supplied in some degree the defect of legal & coercive sanctions, how imperfectly did the States fulfil their obligations to the Union? In time of peace, we see already what is to be expected. How indeed could it be otherwise? In the first place, Every general act of the Union must necessarily bear unequally hard on some particular member or members of it. Secondly the partiality of the members to their own interests and rights, a partiality which will be fostered by the Courtiers of popularity, will naturally exaggerate the inequality where it exists, and even suspect it where it has no existence. Thirdly a distrust of the voluntary compliance of each other may prevent the compliance of any, although it should be the latent disposition of all. Here are causes & pretexts which will never fail to render federal measures abortive. If the laws of the States, were merely recommendatory to their citizens, or if they were to be rejudged by County authorities, what security, what probability would exist, that they would be carried into execution? Is the security or probability greater in favor of the acts of Congs. which depending for their execution on the will of the state legislatures, wch. are tho' nominally authoritative, in fact recommendatory only.
