whatever it was, is without doubt the true foundation, the immediate cause, of African slavery in America. What, then, was this cause? But one answer can be given to this inquiry. On it there can be no division of opinion. It was the state of public opinion in Great Britain, and the state of public opinion in her colonies in this country at the time. This state of public opinion demanded their introduction and employment as slaves, and hence they were introduced and so employed. Whatever demerit or merit, then, was in the origin and maturity of this state of things, is traceable directly to public opinion, and attaches directly as a virtue or a crime, as the case may be, to those who controlled public opinion, through the long period of its inception, formation, and maturity, and to them alone. This being the true origin and foundation of the system, if it had its foundation in _robbery_ and _violence_, it was because public opinion, through that long period, was so eminently corrupt as to set itself, deliberately and of full purpose, to work to perpetrate _robbery_ and _violence_, without any redeeming virtue; for such crimes admit of none. Was this so? Can we be prepared to believe it? In default of all history at this point to detail the origin and progress of public opinion on this subject, we are left to form our judgment from our knowledge of the men whom we know to have participated more largely than any others in directing public opinion in their day, and to the history of the times in which they lived. In the seventeenth century, African slaves were first introduced into this country, and the practice was continued, under the sanction of law, until the years 1778 and 1808, inclusive. At an early period, public opinion was matured on this subject both in England and in the colonies, and we see that for a long period it sustained the practice of introducing slaves directly from Africa into this country. Now, we affirm that the position postulated in regard to this case is among the most palpable absurdities that can be conceived. The character of the men who controlled public opinion in that day, and the patriotic and Christian age in which they lived, utterly disprove the gross assumption that they yielded themselves up to falsify the truth and the conscience that was in them, and become a mere corporation of landpirates and freebooters! If our ignorance of the history of those times should disqualify us to account for the existence of this state of public opinion on any strictly rational grounds, common sense would forbid that we assign for it so unreasonable a cause as this; whilst the least that charity could suggest would be, that we place it among those things for which we were unable to account.
