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.
