It was to this great majority, North and South, that Henry Clay at that critical time appealed. The dominant passion of that statesman's soul was his love of the Union and his desire that it might endure during all time. To that one god of his adoration he had made sacrifices from the beginning. In its behalf he had put aside his lifelong desire for the gradual emancipation of the slaves. In its behalf he had sacrificed the supreme ambition of his life--the ambition to be president. In behalf of the Union he had made himself _anathema maranatha_--at the North as a slaveholder and at the South as an abolitionist. He was in fact both at once. He held slaves under a system of which he could not rid himself without arming them, in Jefferson's phrase, "with freedom and a dagger." He wanted them emancipated and was ready to make sacrifice in that behalf, but on the other hand he desired beyond all other things the preservation of that Union, to the perpetuity of which his whole life had been devoted, and to the perpetuity of which he looked for the enduring memory of whatever was worthy of remembrance in American history. In an extraordinary degree Clay rose above the passions of the hour, as did Webster and certain other statesmen of that time,--though certain other statesmen of the time did not. He saw the situation clearly. The Union had been formed in candid recognition of the fact that slavery existed in full force and effect in certain of the states, while in certain other states, chiefly by reason of its unprofitableness, it was slowly passing away at the time of the Constitution's framing. He perfectly understood that the Constitution was a compact between states that could ratify or reject it at will, and that but for concessions made on the one side and on the other, the Constitution could never have become the fundamental law of the Republic. He clearly understood that the dealings of the Constitution with this question of slavery constituted a compromise to which the moral sentiments and the material interests of both sides were parties. But as has been explained, there had grown up at the North and at the South two parties of extremists who cared little or nothing for the Union and everything for their opposing purposes: the Northern party for the abolition of slavery at all costs, even at cost of the destruction of the Union itself; and the Southern party organized for the perpetuation and extension of slavery regardless of everything else, regardless of the Union and of all that it signified of human liberty and of the practical realization of the doctrine of self-government among men.
