It is said, I know, that the ignorance of the slave is necessary to the security of the master, and the quiet of the state; and this is said truly. Slavery and knowledge cannot live together. To enlighten the slave is to break his chain. To make him harmless, he must be kept blind. He cannot be left to read in an enlightened age, without endangering his master; for what can he read which will not give, at least, some hint of his wrongs? Should his eye chance to fall on "the Declaration of Independence," how would the truth glare on him, "that all men are born free and equal"! All knowledge furnishes arguments against slavery. From every subject light would break forth to reveal his inalienable and outraged rights. The very exercise of his intellect would give him the consciousness of being made for something more than a slave. I agree to the necessity laid on his master to keep him in darkness. And what stronger argument against slavery can be conceived? It compels the master to degrade, systematically, the mind of the slave; to war against human intelligence; to resist that improvement which is the end of the Creator. "Wo to him that taketh away the key of knowledge!" To kill the body is a great crime. The Spirit we cannot kill, but we can bury it in deathlike lethargy; and is this a light crime in the sight of its Maker?

Let it not be said, that almost every where the laboring classes are doomed to ignorance, deprived of the means of instruction. The intellectual advantages of the laboring freeman, who is entrusted with the care of himself, raise him far above the slave; and, accordingly, superior minds are constantly seen to issue from the less educated classes. Besides, in free communities, philanthropy is not forbidden to labor for the improvement of the ignorant. The obligation of the prosperous and instructed to elevate their less favored brethren is taught, and not taught in vain. Benevolence is making perpetual encroachments on the domain of ignorance and crime. In communities, on the other hand, cursed with slavery, half the population, sometimes more, are given up, intentionally and systematically, to hopeless ignorance. To raise this mass to intelligence and self-government is a crime. The sentence of perpetual degradation is passed on a large portion of the human race. In this view, how great the ill desert of slavery!

3. I proceed, now, to the Domestic influences of slavery; and here we must look for a dark picture. Slavery virtually dissolves the domestic relations. It ruptures the most sacred ties on earth. It violates home. It lacerates the best affections. The domestic relations precede, and, in our present existence, are worth more than all our other social ties. They give the first throb to the heart, and unseal the deep fountains of its love. Home is the chief school of human virtue. Its responsibilities, joys, sorrows, smiles, tears, hopes, and solicitudes, form the chief interests of human life. Go where a man may, home is the centre to which his heart turns. The thought of his home nerves his arm and lightens his toil. For that his heart yearns, when he is far off. There he garners up his best treasures. God has ordained for all men alike the highest earthly happiness, in providing for all the sanctuary of home. But the slave's home does not merit the name. To him it is no sanctuary. It is open to violation, insult, outrage. His children belong to another, are provided for by another, are disposed of by another. The most precious burden with which the heart can be charged, the happiness of his child, he must not bear. He lives not for his family, but for a stranger. He cannot improve their lot. His wife and daughter he cannot shield from insult. They may be torn from him at another's pleasure, sold as beasts of burden, sent he knows not whither, sent where he cannot reach them, or even interchange inquiries and messages of love. To the slave marriage has no sanctity. It may be dissolved in a moment at another's will. His wife, son, and daughter may be lashed before his eyes, and not a finger must be lifted in their defence. He sees the scar of the lash on his wife and child. Thus the slave's home is desecrated. Thus the tenderest relations, intended by God equally for all, and intended to be the chief springs of happiness and virtue, are sported with wantonly and cruelly. What outrage so great as to enter a man's house, and tear from his side the beings whom God has bound to him by the holiest ties? Every man can make the case his own. Every mother can bring it home to her own heart.

And let it not be said that the slave has not the sensibilities of other men. Nature is too strong even for slavery to conquer. Even the brute has the yearnings of parental love. But suppose that the conjugal and parental ties of the slave may be severed without a pang. What a curse must be slavery, if it can so blight the heart with more than brutal insensibility, if it can sink the human mother below the polar she-bear, which "howls and dies for her sundered cub!" But it does not and cannot turn the slave to stone. It leaves, at least, feeling enough to make these domestic wrongs occasions of frequent and deep suffering. Still it must do much to quench the natural affections. Can the wife, who has been brought under influences most unfriendly to female purity and honor, who is exposed to the whip, who may be torn away at her master's will, and whose support and protection are not committed to a husband's faithfulness, can such a wife, if the name may be given her, be loved and honored as a woman should be? Or can the love, which should bind together man and his offspring, be expected, under an institution, which subverts, in a great degree, filial dependence and parental authority and care? Slavery withers the affections and happiness of home at their very root, by tainting female purity. Woman, brought up in degradation, placed under another's power and at another's disposal, and never taught to look forward to the happiness of an inviolate, honorable marriage, can hardly possess the feelings and virtues of her sex. A blight falls on her in her early years. Those who have daughters can comprehend her lot. In truth, licentiousness among bond and free is the natural issue of all-polluting slavery. Domestic happiness perishes under its touch, both among bond and free.

How wonderful is it, that in civilized countries men can be so steeled by habit as to invade without remorse the peace, purity, and sacred relations of domestic life, as to put asunder those whom God has joined together, as to break up households by processes more painful than death! And this is done for pecuniary profit! What! Can men, having human feeling, grow rich by the desolation of families? We hear of some of the Southern States enriching themselves by breeding slaves for sale. Of all the licensed occupations of society this is the most detestable. What! Grow men, like cattle! Rear human families, like herds of swine, and then scatter them to the four winds for gain! Among the imprecations uttered by man on man, is there one more fearful, more ominous, than the sighing of the mother bereft of her child by unfeeling cupidity? If blood cry to God, surely that sigh will be heard in heaven.

Let it not be said that members of families are often separated in all conditions of life. Yes, but separated under the influence of love. The husband leaves wife and children, that he may provide for their support, and carries them with him in his heart and hopes. The sailor, in his lonely night-watch, looks homeward, and well known voices come to him amidst the roar of the waves. The parent sends away his children, but sends them to prosper, and to press them again to his heart with a joy enhanced by separation. Are such the separations which slavery makes? And can he, who has scattered other families, ask God to bless his own?

4. I proceed to another important view of the evils of slavery. Slavery produces and gives license to Cruelty. By this it is not meant that cruelty is the universal, habitual, unfailing result. Thanks to God, Christianity has not entered the world in vain. Where it has not cast down, it has mitigated bad institutions. Slavery in this country differs widely from that of ancient times, and from that which the Spaniards imposed on the aboriginals of South America. There is here an increasing disposition to multiply the comforts of the slaves, and in this let us rejoice. At the same time, we must remember, that, under the light of the present day, and in a country where Christianity and the rights of men are understood, a diminished severity may contain more guilt than the ferocity of darker ages. Cruelty in its lighter forms is now a greater crime than the atrocious usages of antiquity at which we shudder. "The times of that ignorance God winked at, but now he calleth men every where to repent." It should also be considered that the slightest cruelty to the slave is an aggravated wrong, because he is unjustly held in bondage, unjustly held as property. We condemn the man who enforces harshly a righteous claim. What, then, ought we to think of lashing and scarring fellow-creatures, for the purpose of upholding an unrighteous, usurped power, of extorting labor which is not our due?

I have said that cruelty is not the habit of the slave States of this country. Still, that it is frequent we cannot doubt. Reports, which harrow up our souls, come to us from that quarter; and we know that they must be essentially correct, because it is impossible that a large part, perhaps the majority, of the population of a country can be broken to passive, unlimited submission, without examples of terrible severity.

Let it not be said, as is sometimes done, that cruel deeds are perpetrated every where else, as well as in slave-countries. Be it so; but in all civilized nations unscourged by slavery, a principal object of legislation is to protect every man from cruelty, and to bring every man to punishment, who wantonly tortures or wounds another; whilst slavery plucks off restraint from the ferocious, or leaves them to satiate their rage with impunity.—Let it not be said that these barbarities are regarded no where with more horror than at the South. Be it so. They are abhorred, but allowed. The power of individuals to lacerate their fellow-creatures is given to them by the community. The community abhors the abuse, but confers the power which will certainly be abused, and thus strips itself of all defence before the bar of Almighty Justice. It must answer for the crimes which are shielded by its laws.—Let it not be said, that these cruelties are checked by the private interest of the slaveholder. Does regard to private interest save from brutal treatment the draught-horse in our streets? And may not a vast amount of suffering be inflicted, which will not put in peril the life or strength of the slave?

To substantiate the charge of cruelty, I shall not, as I have said, have recourse to current reports, however well established. I am willing to dismiss them all as false. I stand on other ground. Reports may lie, but our daily experience of human nature cannot lie. I summon no witnesses, or rather I appeal to a witness every where present, a witness in every heart. Who that has watched his own heart, or observed others, does not feel that man is not fit to be trusted with absolute, irresponsible power over men? It must be abused. The selfish passions and pride of our nature will as surely abuse it, as the storm will ravage, or the ocean swell and roar under the whirlwind. A being, so ignorant, so headstrong, so passionate, as man, ought not to be trusted with this terrible dominion. He ought not to desire it. He ought to dread it. He ought to cast it from him, as most perilous to himself and others.
