How often we have enumerated and deprecated the evils of war!  The Mexican War, in which Slavery herself involved us, (using the power of the Republic against which she conspired to further her conspiracy,) gave us occasion to extol the benefits of peace, and to draw up a formidable indictment against the spirit which lusted for the appeal to arms.  We have not lusted for it, and the benefits of peace seem greater than ever; but the benefits of equity and truth seem greater than all.  Show me justice, or try to make me unjust,—­force upon me at the point of the sword the unspeakable degradation of abetting villany, and I will seize the hilt, if I can, and write my protest clear with the blade, and while I have it in my hand I will reap what advantages are possible in the desolation which it makes.

Among these advantages of a war waged to secure the rights of citizenship to all souls will be the excitement of a national intellectual life, which will take on the various forms of a national literature.  This is to be expected for two reasons.  First, because our arms will achieve unity.  By this is meant not only that there will be a real union of all the States, consequent upon an eventual agreement in great political and moral ideas, but also that this very consent will bring the different characteristic groups of the country so near together, in feeling and mutual appreciation, and with a free interchange of traits, that we shall begin to have a nationality.  And there can be no literature until there is a nation; when the varieties of the popular life begin to coalesce, as all sections are drawn together towards the centre of great political ideas which the people themselves establish, there will be such a rich development of intellectual action as the Old World has not seen.  Without this unity, literature may be cultivated by cliques of men of talent, who are chiefly stimulated to express themselves by observing the thought and beauty which foreign intellects and past times produced; but their productions will not spring from the country’s manifold life, nor express its mighty individuality.  The sections of the country which are nearest to the intelligence of the Old World will furnish the readiest writers and the most polished thinkers, until the New World dwarfs the Old World by its unity, and inspires the best brains with the collected richness of the popular heart.  Up to the period of this war the country’s most original men have been those who, by protesting against its evils and displaying a genius emancipated from the prescriptions of Church and State, have prophesied the revolution, and given to America the first rich foretaste of her growing mind.  The thunder rolled up the sky in the orator’s great periods, the lightning began to gleam in the preacher’s moral indignation, the glittering steel slumbered uneasily and showed its half-drawn menace from the subtle lines of poets and essayists who have been carrying weapons these twenty years;
