The two leading political parties deliberately and persistently sought to evade the issue. The Western pioneers were so fascinated with the vision of millions of pale-faced democrats, leading free and prosperous lives as the reward for virtuously taking care of their own business, that the Constitutional existence of negro slavery did not in the least discommode them. Disunionism they detested and would fight to the end; but to waste valuable time in bothering about a perplexing and an apparently irremediable political problem was in their eyes the worst kind of economy. They were too optimistic and too superficial to anticipate any serious trouble in the Promised Land of America; and they were so habituated to inconsistent and irresponsible political thinking, that they attached no importance to the moral and intellectual turpitude implied by the existence of slavery in a democratic nation. The responsibility of the Whigs for evading the issue is more serious than that of the Democrats. Their leaders were the trained political thinkers of their generation. They were committed by the logic of their party platform to protect the integrity of American national life and to consolidate its organization. But the Whigs, almost as much as the Democrats, refused to take seriously the legal existence of slavery. They shirked the problem whenever they could and for as long as they could; and they looked upon the men who persisted in raising it aloft as perverse fomenters of discord and trouble. The truth is, of course, that both of the dominant parties were merely representing the prevailing attitude towards slavery of American public opinion. That attitude was characterized chiefly by moral and intellectual cowardice. Throughout the whole of the Middle Period the increasing importance of negro servitude was the ghost in the house of the American democracy. The good Americans of the day sought to exorcise the ghost by many amiable devices. Sometimes they would try to lock him up in a cupboard; sometimes they would offer him a soothing bribe; more often they would be content with shutting their eyes and pretending that he was not present. But in proportion as he was kindly treated he persisted in intruding, until finally they were obliged to face the alternative, either of giving him possession of the house or taking possession of it themselves.
Foreign commentators on American history have declared that a peaceable solution of the slavery question was not beyond the power of wise and patriotic statesmanship. This may or may not be true. No solution of the problem could have been at once final and peaceable, unless it provided for the ultimate extinction of slavery without any violation of the Constitutional rights of the Southern states; and it may well be that the Southern planters could never have been argued or persuaded into abolishing an institution which they eventually came to believe was a righteous method of dealing with an inferior race. Nobody can assert with any confidence that they could have been brought by candid, courageous, and just negotiation and discussion into a reasonable frame of mind; but what we do know and can assert is that during the three decades from 1820 to 1850, the national political leaders made absolutely no attempt to deal resolutely, courageously, or candidly with the question. On those occasions when it would come to the surface, they contented themselves and public opinion with meaningless compromises. It would have been well enough to frame compromises suited to the immediate occasion, provided the problem of ultimately extinguishing slavery without rending the Union had been kept persistently on the surface of political discussion: but the object of these compromises was not to cure the disease, but merely to allay its symptoms. They would not admit that slavery was a disease; and in the end this habit of systematic drifting and shirking on the part of moderate and sensible men threw the national responsibility upon Abolitionist extremists, in whose hands the issue took such a distorted emphasis that gradually a peaceable preservation of American national integrity became impossible.
The problem of slavery was admirably designed to bring out the confusion of ideas and the inconsistency resident in the traditional American political system. The groundwork of that system consisted, as we have seen, in the alliance between democracy, as formulated in the Jeffersonian creed, and American nationality, as embodied in the Constitutional Union; and the two dominant political parties of the Middle Period, the Whigs and the Jacksonian Democrats, both believed in the necessity of such an alliance. But negro slavery, just in so far as it became an issue, tended to make the alliance precarious. The national organization embodied in the Constitution authorized not only the existence of negro slavery, but its indefinite expansion. American democracy, on the other hand, as embodied in the Declaration of Independence and in the spirit and letter of the Jeffersonian creed, was hostile from certain points of view to the institution of negro slavery. Loyalty to the Constitution meant disloyalty to democracy, and an active interest in the triumph of democracy seemed to bring with it the condemnation of the Constitution. What, then, was a good American to do who was at once a convinced democrat and a loyal Unionist?
The ordinary answer to this question was, of course, expressed in the behavior of public opinion during the Middle Period. The thing to do was to shut your eyes to the inconsistency, denounce anybody who insisted on it as unpatriotic, and then hold on tight to both horns of the dilemma. Men of high intelligence, who really loved their country, and believed in the democratic idea, persisted in this attitude, whose ablest and most distinguished representative was Daniel Webster. He is usually considered as the most eloquent and effective expositor of American nationalism who played an important part during the Middle Period; and unquestionably he came nearer to thinking nationally than did any American statesman of his generation. He defended the Union against the Nullifiers as decisively in one way as Jackson did in another. Jackson flourished his sword, while Webster taught American public opinion to consider the Union as the core and the crown of the American political system. His services in giving the Union a more impressive place in the American political imagination can scarcely be over-estimated. Had the other Whig leaders joined him in refusing to compromise with the Nullifiers and in strengthening by legislation the Federal government as an expression of an indestructible American national unity, a precedent might have been established which would have increased the difficulty of a subsequent secessionist outbreak. But Henry Clay believed in compromises (particularly when his own name was attached to them) as the very substance of a national American policy; and Webster was too much of a Presidential candidate to travel very far on a lonely path. Moreover, there was a fundamental weakness in Webster's own position, which was gradually revealed as the slavery crisis became acute. He could be bold and resolute, when defending a nationalistic interpretation of the Constitution against the Nullifiers or the Abolitionists; but when the slaveholders themselves became aggressive in policy and separatist in spirit, the courage of his convictions deserted him. If an indubitably Constitutional institution, such as slavery, could be used as an ax with which to hew at the trunk of the Constitutional tree, his whole theory of the American system was undermined, and he could speak only halting and dubious words. He was as much terrorized by the possible consequences of any candid and courageous dealing with the question as were the prosperous business men of the North; and his luminous intelligence shed no light upon a question, which evaded his Constitutional theories, terrified his will, and clouded the radiance of his patriotic visions.
The patriotic formula, of which Webster was the ablest and most eloquent expositor, was fairly torn to pieces by the claws of the problem of slavery. The formula triumphantly affirmed the inseparable relation between individual liberty and the preservation of the Federal Union; but obviously such a formula could have no validity from the point of view of a Southerner. The liberties which men most cherish are those which are guaranteed to them by law—among which one of the most important from the Southerner's point of view was the right to own negro bondsmen. As soon as it began to appear that the perpetuation of the Union threatened this right, they were not to be placated with any glowing proclamation about the inseparability of liberty in general from an indestructible union. From the standpoint of their own most cherished rights, they could put up a very strong argument on behalf of disunion; and they had as much of the spirit of the Constitution on their side as had their opponents. That instrument was intended not only to give legal form to the Union of the
