Those votes for the extension of the slave trade were given undoubtedly in behalf of the mercantile interest of the maritime states of the northeast, and they reflected no moral conviction whatsoever. For there was at that time no moral conviction of the wrongfulness of slavery anywhere in the country. The thought that the negro was a man, endowed by his Creator with an unalienable right to "life, liberty, and the pursuit of happiness," had not yet been born in America. And even after thirty odd years, and a dozen years after the constitutional prohibition of the African slave trade had gone into effect, that unlawful traffic in human beings was still so gainful an occupation to merchants and shipmasters, that Mr. Justice Joseph Story, himself a New Englander and a judge of the Supreme Court of the United States, was bitterly denounced by the New England press and public as a judge who deserved to be "hurled from the bench," because he had instructed grand juries that it was their sworn duty to indict the men who were still engaged in the nefarious business of transporting slaves, under conditions of unspeakable cruelty, from Africa to these shores. The offense of that great jurist lay in the fact that he regarded the demands of the constitution and the law as more binding upon his character and conscience than the demands of the New England slave traders whose very profitable business his insistence upon the rigid enforcement of the law threatened to embarrass and destroy. As there are now no advocates of slavery in our free land; as all of us, North and South alike, are agreed that the institution was a curse the maledictions of which endure to the present day in vexatious "race problems;" it is possible and proper now to record all facts respecting it with impartiality and without controversial intent. It is of supreme importance to any clear understanding of this matter to bear in mind the fact that our modern conceptions of human rights did not exist in the earlier times; that the recognition of the negro as "a man and a brother" is the birth of comparatively recent thought; that the traffic in black human beings, captured in Africa and brought hither for sale as laborers, excited no impulse of antagonism, offended no moral sentiment, and seemed to nobody in the earlier times a violation of those fundamental doctrines of human right upon which this Republic is based. All that has been a glorious after-thought, and it is solely with an expository purpose and not at all as a _tu quoque_ that these facts of history are here set forth.
