War is always an epoch. Unhappily, history counts by wars. Of these, some are wars of ideas,--like that between Catholics and Huguenots in France, between Catholics and Protestants in Germany, between the arbitrary crown of Charles the First and the Puritanism of Oliver Cromwell, and like that between our fathers and the mother country, when the Declaration of Independence was put in issue. Some originate in questions of form, some in the contentions of families, some in the fickleness of princes, and some in the machinations of politicians. England waged war on Holland, and one of the reasons openly assigned was an offensive picture in the Town-Hall of Amsterdam. France hurled armies across the Rhine, carrying fire and slaughter into the Palatinate, and involving great nations in most bloody conflict,--and all this wickedness is traced to the intrigue of a minister, to divert the attention of his sovereign. But we are now in the midst of a war which, whatever the reasons assigned by the unhappy men who began it, or by those who sympathize with them elsewhere, has an origin and mainspring so clear and definite as to be beyond question. Ideas are sometimes good and sometimes bad; and there may be a war for evil as well as for good. Such was that earliest rebellion waged by fallen spirits against the Almighty Throne; and such is that now waged by fallen slave-masters of our Republic against the National Government. I adopt the language of Milton, in his masterly prose, when I call it “a war fit for Cain to be the leader of,--an abhorred, a cursed, a fraternal war.”[205] Nor can any courage in Rebels give true honor. If victorious, they will be only Satanic saints of Slavery, with place in a most hateful hagiology. If you will kindly listen, I shall endeavor to unmask this Rebellion in its Origin and Mainspring. Only when these are known can you determine how it is to be treated. Your efforts will be governed by the character of the adverse force,--whether regarded as motive power or as disease. A steam-engine is stopped at once by stopping the steam. A ghastly cancer, which has grappled the very fibres of the human frame, and shot its poison through every vein, will not yield to lip-salve or rosewater. “Diseases desperate grown By desperate appliances are relieved, Or not at all.”
