To begin with Africa. If we would form a fair calculation of the aggregate sum of misery caused by the Slave Trade, we must remember that it is by no means to be estimated by the numbers which we actually carry away into slavery: Nor yet by adding to them all the wretched relatives, families, and connections who are left behind: Nor yet by superadding the devastation and misery which, to those who may not actually be caught and carried off, may arise from all the several predatory expeditions occasioned by the Slave Trade, either directly or in retaliation of former aggressions originating from the same cause: Nor still by adding the destruction and desolation produced by national wars (for of these the Slave Trade is often the origin), with pestilence and famine, and all the various forms of misery which follow war in its train: Nor even yet by subjoining the wretchedness of those, with all their families and friends, who are the victims of injustice and treachery, masking themselves under the forms of law, or availing themselves of the native superstitions.

But let us endeavour to make the case our own, and to consider what it would be to live in a country subject to such continual depredations by night, and such treachery by day. These evils affect the whole condition of society; they poison the happiness of every family, nay, it may almost be said of every individual in the community. All the nameless but sweet enjoyments comprised within the idea of home, to all of which security is necessary, are at once destroyed; and Parke assures us that no people taste these pleasures with a higher relish than the Negroes.

Consider the intensity of the sufferings which the Slave Trade occasions in Africa, and the number of the sufferers; remember throughout what an immense extent these evils prevail, and the time they have continued.

To this vast mass of African misery, add up all the various evils of the middle passage. See there the husband and father, wife and mother, who have been torn from the dearest objects of their affections, and are now carried away, they know not whither, in their floating prison. Take in, their never having been before at sea, their confinement, their posture, with all the other distressing particulars of their situation; is not too much to say that you see them enduring exquisite bodily suffering. But, much more, consider the sorrows of the mind; see them dying of a broken heart, from the loss of their friends and country, from their remembrance of the past, and their prospect for the future. In this state forced to bear the coarse brutality of the sailors, and urged by stripes, with a stomach loathing food, to eat; and with limbs galled with fetters, to dance; while their hearts are wrung with agony. Consider then that in every individual Slave ship there are most likely multitudes of these wretched beings; many of them men, as Mr. Parke tells us, of some education; some of them men of considerable rank in their own country: but the whole cargo, as it is hatefully termed, consists of husbands and wives, of parents and children—all had a home—all had relatives.

But to the sufferings of the wretched Slaves themselves, we must add those of the sailors also, who are too often treated with extreme barbarity. Of the latter, there are not a few who, though their lives are spared, lose their health, their sight, or the use of their limbs, not merely from the unwholesome nature of the climate of Africa, but from various peculiarities attendant on the Slave Trade.

Nor ought we to omit the moral injury which our country sustains from the number of persons who are rendered ferocious and unfeeling by the hardening nature of their constant occupation.

It would be difficult to add up the different items, much less to discover the precise sum of the misery which may fairly be placed to the account of the Slave Trade in the West Indies. Here, however, let me first remark, and it ought to have been observed in the case of Africa likewise, the Slave Trade is justly chargeable with the prevention of all that domestic happiness and social comfort and prosperity which would follow from the introduction of the domestic system which it naturally supersedes. But when we proceed to the positive articles of this account; when we endeavour to sum up the total of the immense number of individual sufferers: Again, when to these we add the sufferings and the waste of our brave defenders, by sea and land, with the sorrows of their surviving relatives; and when we consider the unknown amount of evil, which, from the effect on the minds of our soldiers and sailors, may at some time or other result from this class of ravages, evil possibly commensurate with the ruin of our country: When we remember that it is the Slave Trade which prolongs the internal weakness of our West Indian colonies, that it is this weakness which invites attack, and thence creates the necessity of defence at such a profuse expenditure of the lives of our countrymen; and that the facility of conquering these possessions operates powerfully as a temptation to our enemies to commence war, with all its unknown miseries and dangers: By what new denomination shall we in any degree fairly express the real sum of these several items?

There is still, however, another class of evils on which I have occasionally touched, which will appear of the highest amount to all considerate men, to whom the best interests of their country are dear, and who have been accustomed to trace the operation of those causes which have led to the decline and fall of nations.[[55]] These are the moral evils both of the Slave Trade, and even, still more, because of greater extent, of the system of West Indian slavery. It is the fashion of the present day to pay little attention to evils of this class; but they are not on this account less real or less efficient. Their nature and force have been acknowledged by all writers of eminence, whether ancient or modern, who have treated either of the prosperity or decay of the great nations of antiquity.

The system of slavery, especially of slavery in it’s more hateful forms, never did nor ever will prevail long in any country, without producing a most pernicious effect, both on it’s morals, habits, and manners. This is an invidious topic, on which I will not enlarge; but let it’s amount be duly estimated by all who are interested for the independence, the prosperity, or the happiness of their country. When all these various masses of misery are piled up into one, who shall attempt to take the dimensions of it’s enormous bulk. Yet we must acknowledge, that from it’s very size it produces less impression on mankind in general. This principle may be termed a law of our nature, and we suffer from the effect of it in every part of our great cause. I firmly believe that it is here the Slave Trade has found it’s chief security. Had it not been for the operation of this cause, both Houses of Parliament, I had almost said the whole nation, would have risen with one indignant effort, and have forced the Slave Traders to desist from their cruel occupation. Could we but place even the people of Liverpool themselves, where they could see with their own eyes the progress, from first to last, of this series of crimes and cruelties; could we but confine their attention so that they might have but one object before them at once, and might view it in all it’s parts distinctly, with all it’s circumstances and relations, I firmly believe they would themselves abjure that inhuman traffic for which they are now so ignominiously preeminent.

But the enormous dimensions of this mass of misery are such, that our organs are not fitted for the contemplation of it; our affections are not suited to deal with it; we are lost in the immensity of the prospect; we are distracted by it’s variety. We may see highly probable reasons why our all wise Creator has so constituted us, that we are more deeply affected by one single tale of misery, with all the details of which we are acquainted, than by the greatest accumulation of sufferings of which the particulars have not fallen under our notice. Could I but separate this immense aggregate into all its component parts, and present them one by one to your view, in all their particularity of wretchedness, you would then have a more just impression of the immensity of the misery which we wish to terminate. This cannot now be done; but let us, in concluding our melancholy course, employ a few moments in taking some family, or some individual Negro, and following him through all his successive stages of suffering, from his first becoming the victim of some nightly attack on his dwelling, or from his being sentenced to slavery for the benefit of those who condemned him, to the final close of his wretched life. I will not attempt to describe his sufferings; estimate from your own feelings what must be his, in all the various situations through which he passes.
