But the indissoluble link of union between the people of the several States of this confederated nation is, after all, not in the RIGHT, but in the HEART.
If the day should ever come (may Heaven avert it !) when the affections of the people of these States shall be alienated from each other, when the fraternal spirit shall give way to cold indifference, or collision of interests shall fester into hatred, the bonds of political association - will not long hold together parties no longer attracted by the magnetism of conciliated interests and kindly sympathies ; and far better will it be for the people of the disunited States to part in friendship with each other than to be held together by constraint.
Then will be the time for reverting to the precedents which occurred at the formation and adoption of the Constitution, to form again a more perfect Union, by dissolving that which could no longer bind, and to leave the separated parts to be reunited by the law of political gravitation to the center.
John Quincy Adams
