Sir, the human mind is so constituted, that the merits of both sides of a controversy appear very clear, and very palpable, to those who respectively espouse them; and both sides usually grow clearer as the controversy advances. South Carolina sees unconstitutionality in the tariff; she sees oppression there also, and she sees danger. Pennsylvania, with a vision not less sharp, looks at the same tariff, and sees no such thing in it; she sees it all constitutional, all useful, all safe. The faith of South Carolina is strengthened by opposition, and she now not only sees, but _resolves_, that the tariff is palpably unconstitutional, oppressive, and dangerous; but Pennsylvania, not to be behind her neighbors, and equally willing to strengthen her own faith by a confident asseveration, _resolves_, also, and gives to every warm affirmative of South Carolina, a plain, downright, Pennsylvania negative. South Carolina, to show the strength and unity of her opinion, brings her assembly to a unanimity, within seven voices; Pennsylvania, not to be outdone in this respect any more than in others, reduces her dissentient fraction to a single vote. Now, Sir, again, I ask the gentleman, What is to be done? Are these States both right? Is he bound to consider them both right? If not, which is in the wrong? or rather, which has the best right to decide? And if he, and if I, are not to know what the Constitution means, and what it is, till those two State legislatures, and the twenty-two others, shall agree in its construction, what have we sworn to, when we have sworn to maintain it? I was forcibly struck, Sir, with one reflection, as the gentleman went on in his speech. He quoted Mr. Madison's resolutions, to prove that a State may interfere, in a case of deliberate, palpable, and dangerous exercise of a power not granted. The honorable member supposes the tariff law to be such an exercise of power; and that consequently a case has arisen in which the State may, if it see fit, interfere by its own law. Now it so happens, nevertheless, that Mr. Madison deems this same tariff law quite constitutional. Instead of a clear and palpable violation, it is, in his judgment, no violation at all. So that, while they use his authority for a hypothetical case, they reject it in the very case before them. All this, Sir, shows the inherent futility, I had almost used a stronger word, of conceding this power of inference to the State, and then attempting to secure it from abuse by imposing qualifications of which the States themselves are to judge. One of two things is true; either the laws of the Union are beyond the discretion and beyond the control of the States; or else we have no constitution of general government, and are thrust back again to the days of the Confederation.
