The election in November turns on the single and simple question, Whether we shall consent to the indefinite multiplication of them; and the only party which stands plainly and unequivocally pledged against such a policy, nay, which is not either openly or impliedly in favor of it,--is the Republican party. We are of those who at first regretted that another candidate was not nominated at Chicago; but we confess that we have ceased to regret it, for the magnanimity of Mr. Seward since the result of the Convention was known has been a greater ornament to him and a greater honor to his party than his election to the Presidency would have been. We should have been pleased with Mr. Seward's nomination, for the very reason we have seen assigned for passing him by,--that he represented the most advanced doctrines of his party. He, more than any other man, combined in himself the moralist's oppugnancy to Slavery as a fact, the thinker's resentment of it as a theory, and the statist's distrust of it as a policy,--thus summing up the three efficient causes that have chiefly aroused and concentrated the antagonism of the Free States. Not a brilliant man, he has that best gift of Nature, which brilliant men commonly lack, of being always able to do his best; and the very misrepresentation of his opinions which was resorted to in order to neutralize the effect of his speeches in the Senate and elsewhere was the best testimony to their power. Safe from the prevailing epidemic of Congressional eloquence as if he had been inoculated for it early in his career, he addresses himself to the reason, and what he says sticks. It was assumed that his nomination would have embittered the contest and tainted the Republican creed with radicalism; but we doubt it. We cannot think that a party gains by not hitting its hardest, or by sugaring its opinions. Republicanism is not a conspiracy to obtain office under false pretences. It has a definite aim, an earnest purpose, and the unflinching tenacity of profound conviction. It was not called into being by a desire to reform the pecuniary corruptions of the party now in power. Mr. Bell or Mr. Breckinridge would do that, for no one doubts their honor or their honesty. It is not unanimous about the Tariff, about State-Rights, about many other questions of policy. What unites the Republicans is a common faith in the early principles and practice of the Republic, a common persuasion that slavery, as it cannot but be the natural foe of the one, has been the chief debaser of the other, and a common resolve to resist its encroachments everywhen and everywhere. They see no reason to fear that the Constitution, which has shown such pliant tenacity under the warps and twistings of a forty-years' pro-slavery pressure, should be in danger of breaking, if bent backward again gently to its original rectitude of fibre. "All forms of human government," says Machiavelli, "have, like men, their natural term, and
