Among those who have advocated views adverse to those of our present study, we are compelled to notice Dr. Paley, as one of the most influential, the most dignified, and the most learned. He defines slavery to be “an obligation to labour for the benefit of the master, without the contract or consent of the servant.” He says “that this obligation may arise, consistently with the laws of nature, from three causes: 1st, from crimes; 2d, from captivity; and 3d, from debt.” He says that, “in the first case, the continuance of the slavery, as of any other punishment, ought to be proportionate to the crime. In the second and third cases, it ought to cease as soon as the demand of the injured nation or private creditor is satisfied.” He was among the first to oppose the African slave-trade. He says, “Because, when the slaves were brought to the African slave-market, no questions were asked as to the origin of the vendors’ titles: Because the natives were incited to war for the sake of supplying the market with slaves: Because the slaves were torn away from their parents, wives, children, and friends, homes, companions, country, fields, and flocks, and their accommodation on shipboard not better than that provided for brutes: Because the system of laws by which they are governed is merciless and cruel, and is exercised, especially by their English masters, with rigour and brutality.” But he thinks the American Revolution, which had just then happened, will have a tendency to accelerate the fall of this most abominable tyranny, and indulges in the reflection whether, in the providence of God, the British legislature, which had so long assisted and supported it, was fit to have rule over so extensive an empire as the North American colonies. Dr. Paley says that slavery was a part of the civil constitution of most countries when Christianity appeared; and that no passage is found in the Christian Scriptures by which it is condemned or prohibited. But he thinks the reason to be, because “Christianity, soliciting admission into all nations of the world, abstained, as behooved it, from intermeddling with the civil institutions of any; but,” says he, “does it follow from the silence of Scripture concerning them, that all the civil institutions that then prevailed were right? or, that the bad should not be exchanged for better? Besides,” he says, “the discharging the slaves from all obligations to their masters would have had no better effect than to let loose one half of mankind upon the other. Besides,” he thinks “it would have produced a servile war, which would have ended in the reproach and extinction of the Christian name.”
