Great, however, as these results have been, the fact is so plain that he who runs may read, that they would have been vastly greater but for a malignant influence which has met the elements of progress, even on these shores. Disengaged from the opposing influences which surrounded them in Europe--from the spirit of absolutism, of hereditary aristocracy, of ecclesiastical despotism, from the habits, the customs, the institutions of earlier times, more or less rigid, unyielding on that account, and hard to change by the new forces, disengaged from these hampering influences, and planted on the shores of America--these elements of progress, so retarded even up to the present moment in Europe, found themselves most unexpectedly side by side with an outbirth of human selfishness in its pure and most undisguised form. This was not the spirit of absolutism, or of hereditary aristocracy, nor of ecclesiastical and priestly domination. All of these, which have so conspicuously figured in Europe, have perhaps done more at certain periods for the advancement of civilization, by their restraining, educating influence, than they have done harm at others, when less needed. All of these institutions arose naturally out of the circumstances, the character, and wants of men, at the time, and have been of essential service in their day. But the great antagonist which free principles encountered on American soil; which was planted alongside of the tree of liberty; which grew with its growth, and strengthened with its strength; which, like a noxious parasitic vine, wound its insidious coils around the trunk that supported it--binding its expanding branches, rooted in its tissues, and living on its vital fluids;--this insidious enemy was slavery--a thoroughly undisguised manifestation of human selfishness and greed; without a single redeeming trait--simply an unmitigated evil: a two-edged weapon, cutting and maiming both ways, up and down--the master perhaps even more than the slave; a huge evil committed, reacting in evil, in the exact degree of its hugeness and momentum. Yes! this great antagonist was slavery--an institution long thrown out of European life; a relic of the lowest barbarism and savagism, the very antipodes of freedom, and flourishing best only in the rudest forms of society; but now rearing its hideous visage in the midst of principles, forms, and institutions the most free and advanced of any that the world has ever witnessed.
