and valleys, and from thence travel onward over the Palisades of the Hudson, and down the soft flowing waters of the Delaware and gild the waves of the Potomac, “hitherto shalt thou come and no further;” I know that even professors of His name who has been emphatically called the “Light of the world” would, if they could, build a wall of adamant around the Southern States whose top might reach unto heaven, in order to shut out the light which is bounding from mountain to mountain and from the hills to the plains and valleys beneath, through the vast extent of our Northern States.  But believe me, when I tell you, their attempts will be as utterly fruitless as were the efforts of the builders of Babel; and why?  Because moral, like natural light, is so extremely subtle in its nature as to overleap all human barriers, and laugh at the puny efforts of man to control it.  All the excuses and palliations of this system must inevitably be swept away, just as other “refuges of lies” have been, by the irresistible torrent of a rectified public opinion.  “The supporters of the slave system,” says Jonathan Dymond in his admirable work on the Principles of Morality, “will hereafter be regarded with the same public feeling, as he who was an advocate for the slave trade now is.”  It will be, and that very soon, clearly perceived and fully acknowledged by all the virtuous and the candid, that in principle it is as sinful to hold a human being in bondage who has been born in Carolina, as one who has been born in Africa.  All that sophistry of argument which has been employed to prove, that although it is sinful to send to Africa to procure men and women as slaves, who have never been in slavery, that still, it is not sinful to keep those in bondage who have come down by inheritance, will be utterly overthrown.  We must come back to the good old doctrine of our forefathers who declared to the world, “this self evident truth that all men are created equal, and that they have certain inalienable rights among which are life, liberty, and the pursuit of happiness.”  It is even a greater absurdity to suppose a man can be legally born a slave under our free Republican Government, than under the petty despotisms of barbarian Africa.  If then, we have no right to enslave an African, surely we can have none to enslave an American; if it is a self evident truth that all men, every where and of every color are born equal, and have an inalienable right to liberty, then it is equally true that no man can be born a slave, and no man can ever rightfully be reduced to involuntary bondage and held as a slave, however fair may be the claim of his master or mistress through wills and title-deeds.
