On the occasion which has given rise to this meeting, the proposition contended for in opposition to the doctrine just stated was that every State, under certain supposed exigencies, and in certain supposed cases, might decide for itself, and act for itself, and oppose its own force to the execution of the laws. By what argument, do you imagine, Gentlemen, was such a proposition maintained? I should call it metaphysical and subtle; but these terms would imply at least ingenuity, and some degree of plausibility; whereas the argument appears to me plain assumption, mere perverse construction of plain language in the body of the Constitution itself. As I understand it, when put forth in its revised and most authentic shape, it is this: that the Constitution provides that any amendments may be made to it which shall be agreed to by three fourths of the States; there is, therefore, to be nothing in the Constitution to which three fourths of the States have not agreed. All this is true; but then comes this inference, namely, that, when one State denies the constitutionality of any law of Congress, she may arrest its execution as to herself, and keep it arrested, till the States can all be consulted by their conventions, and three fourths of them shall have decided that the law is constitutional. Indeed, the inference is still stranger than this; for State conventions have no authority to construe the Constitution, though they have authority to amend it; therefore the argument must prove, if it prove any thing, that, when any one State denies that any particular power is included in the Constitution, it is to be considered as not included, and cannot be found there till three fourths of the States agree to insert it. In short, the result of the whole is, that, though it requires three fourths of the States to insert any thing in the Constitution, yet any one State can strike any thing out of it. For the power to strike out, and the power of deciding, without appeal, upon the construction of what is already in, are substantially and practically the same.
And, Gentlemen, what a spectacle should we have exhibited under the actual operation of notions like these! At the very moment when our government was quoted, praised, and commended all over the world, when the friends of republican liberty everywhere were gazing at it with delight, and were in perfect admiration at the harmony of its movements, one State steps forth, and, by the power of nullification, breaks up the whole system, and scatters the bright chain of the Union into as many sundered links as there are separate States!
Seeing the true grounds of the Constitution thus attacked, I raised my voice in its favor, I must confess with no preparation or previous intention. I can hardly say that I embarked in the contest from a sense of duty. It was an instantaneous impulse of inclination, not acting against duty, I trust, but hardly waiting for its suggestions. I felt it to be a contest for the integrity of the Constitution, and I was ready to enter into it, not thinking, or caring, personally, how I might come out.
