Mr. President, if I considered the constitutional question now before us as doubtful as it is important, and if I supposed that its decision, either in the Senate or by the country, was likely to be in any degree influenced by the manner in which I might now discuss it, this would be to me a moment of deep solicitude. Such a moment has once existed. There has been a time, when, rising in this place, on the same question, I felt, I must confess, that something for good or evil to the Constitution of the country might depend on an effort of mine. But circumstances are changed. Since that day, Sir, the public opinion has become awakened to this great question; it has grasped it; it has reasoned upon it, as becomes an intelligent and patriotic community, and has settled it, or now seems in the progress of settling it, by an authority which none can disobey, the authority of the people themselves. I shall not, Mr. President, follow the gentleman, step by step, through the course of his speech. Much of what he has said he has deemed necessary to the just explanation and defence of his own political character and conduct. On this I shall offer no comment. Much, too, has consisted of philosophical remark upon the general nature of political liberty, and the history of free institutions; and upon other topics, so general in their nature as to possess, in my opinion, only a remote bearing on the immediate subject of this debate. But the gentleman's speech made some days ago, upon introducing his resolutions, those resolutions themselves, and parts of the speech now just concluded, may, I presume, be justly regarded as containing the whole South Carolina doctrine. That doctrine it is my purpose now to examine, and to compare it with the Constitution of the United States. I shall not consent, Sir, to make any new constitution, or to establish another form of government. I will not undertake to say what a constitution for these United States ought to be. That question the people have decided for themselves; and I shall take the instrument as they have established it, and shall endeavor to maintain it, in its plain sense and meaning, against opinions and notions, which, in my judgment, threaten its subversion. The resolutions introduced by the gentleman were apparently drawn up with care, and brought forward upon deliberation. I shall not be in danger, therefore, of misunderstanding him, or those who agree with him, if I proceed at once to these resolutions, and consider them as an authentic statement of those opinions upon the great constitutional question by which the recent proceedings in South Carolina are attempted to be justified. These resolutions are three in number. The third seems intended to enumerate, and to deny, the several opinions expressed in the President's proclamation, respecting the nature and powers of this government. Of this third resolution, I purpose, at present, to take no particular notice.
