Mr. Seward hangs out the signal of uncompromising conflict. This, in effect, if not in words, says he, is the Holy Land of freedom and universal equality. Infidels and barbarians possess it in all its Southern borders, and hold there black christians their coequals in all the rights of men in an inhuman bondage. Let us then by the aid of the exiles from foreign lands overcome the infidels and barbarians, and plant in all that fair domain the standard of the higher law, of universal suffrage and universal equality; and forthwith all through the North, Republican _Wide-Awakes_ muster their forces for this great political crusade. I am drawing no fancy picture. What I say is but a legitimate comment upon the language of Mr. Seward in his Chicago speech, already referred to, and in other speeches he has made during his recent pilgrimage through the North-west. Mr. Seward is the self-constituted exponent of the _higher law_ in its application to political parties and measures, and to Constitutions and systems of government, but in his pursuit of one idea, he seems to forget that the sacred volume to which we all look as the source of our best and truest knowledge of the will and purposes of Providence concerning man, if it clearly reveals to us any thing, clearly reveals this fact, which all human history confirms: that man is not a perfect being; that this earth is not a perfect state; that disorder, and imperfection, and inequality, and change must ever pervade it, and mark all human institutions. This earth and its mortal life is but the threshhold--the vestibule of human destiny--that reaches far into the eternal ages. Believe, as he may, in human equality or in the perfectibility of humanity, no such theory has ever yet been realized, nor will it ever be realized in this probationary state of man. Philosophy may teach--political constitutions may declare, and political parties may attempt to enforce as a practical truth, that all men are equal. No such theory will ever find a perfect realization in any system of human government.
