It would be endless, he said, to go into all the cases, which would manifest the impolicy of this odious traffic. Inhuman as it was, unjust as it was, he believed it to be equally impolitic; and if their lordships should be of this opinion also, he hoped they would agree to that part of the resolution, in which these truths were expressed. With respect to the other part of it, or that they would proceed to abolish the trade, he observed, that neither the time nor the manner of doing it were specified. Hence if any of them should differ as to these particulars, they might yet vote for the resolution; as they were not pledged to any thing definite in these respects; provided they thought that the trade should be abolished at some time or other; and he did not believe, that there was any one of them, who would sanction its continuance for ever.
Lord Hawkesbury said, that he did not mean to discuss the question on the ground of justice and humanity, as contradistinguished from sound policy. If it could fairly be made out, that the African Slave-trade was contrary to justice and humanity, it ought to be abolished. It did not, however, follow, because a great evil subsisted, that therefore it should be removed; for it might be comparatively a less evil, than that which would accompany the attempt to remove it. The noble lord, who had just spoken, had exemplified this: for though slavery was a great evil in itself, he was of opinion, that it could not be done away but in a course of time.
A state of slavery, he said, had existed in Africa from the earliest time; and, unless other nations would concur with England in the measure of the abolition, we could not change it for the better.
Slavery had existed also throughout all Europe. It had now happily in a great measure been done away. But how? Not by acts of parliament; for these might have retarded the event; but by the progress of civilization, which removed the evil in a gradual and rational manner.
He then went over the same ground of argument, as when a member of the Commons in 1792. He said that the inhumanity of the abolition was visible in this, that not one slave less would be taken from Africa; and that such, as were taken from it, would suffer more than they did now, in the hands of foreigners. He maintained also, as before, that the example of St. Domingo afforded one of the strongest arguments against the abolition of the trade. And he concluded by objecting to the resolution, inasmuch as it could do no good; for the substance of it would be to be discussed again in a future session.
The Bishop of London (Dr. Porteus) began by noticing the concession of the last speaker, namely, that, if the trade was contrary to humanity and justice, it ought to be abolished. He expected, he said, that the noble lord would have proved, that it was not contrary to these great principles, before he had supported its continuance; but not a word had he said to show, that the basis of the resolution in these respects was false. It followed then, he thought, that as the noble lord had not disproved the premises, he was bound to abide by the conclusion.
