Such a being was plainly made for an End in Himself. He is a Person, not a Thing. He is an End, not a mere Instrument or Means. He was made for his own virtue and happiness. Is this end reconcilable with his being held and used as a chattel? The sacrifice of such a being to another's will, to another's present, outward, ill-comprehended good, is the greatest violence which can be offered to any creature of God. It is to degrade him from his rank in the universe, to make him a means, not an end, to cast him out from God's spiritual family into the brutal herd. Such a being was plainly made to obey a Law within Himself. This is the essence of a moral being. He possesses, as a part of his nature, and the most essential part, a sense of Duty, which he is to reverence and follow, in opposition to all pleasure or pain, to all interfering human wills. The great purpose of all good education and discipline is, to make a man Master of Himself, to excite him to act from a principle in his own mind, to lead him to propose his own perfection as his supreme law and end. And is this highest purpose of man's nature to be reconciled with entire subjection to a foreign will, to an outward, overwhelming force, which is satisfied with nothing but complete submission? The end of such a being as we have described is manifestly Improvement. Now, it is the fundamental law of our nature, that all our powers are to improve by free exertion. Action is the indispensable condition of progress to the intellect, conscience, and heart. Is it not plain, then, that a human being cannot, without wrong, be owned by another, who claims, as proprietor, the right to repress the powers of his slaves, to withhold from them the means of development, to keep them within the limits which are necessary to contentment in chains, to shut out every ray of light and every generous sentiment, which may interfere with entire subjection to his will?
