"A great deal is said, to be sure, about the rights of the South; but has any such right been infringed? When a man invests money in any species of property, he assumes the risks to which it is liable. If he buy a house, it may be burned; if a ship, it may be wrecked; if a horse or an ox, it may die. Now the disadvantage of the Southern kind of property is - how shall we say it so as not to violate our Constitutional obligations? - that it is exceptional. When it leaves Virginia, it is a thing; when it arrives in Boston, it becomes a man, speaks human language, appeals to the justice of the same God whom we all acknowledge, weeps at the memory of wife and children left behind - in short, hath the same organs and dimension that a Christian hath, and is not distinguishable from ordinary Christians, except, perhaps, by a simpler and more earnest faith. There are people at the North who believe, that, beside meum and tuum, there is also such a thing as suum, - who are old-fashioned enough, or weak enough, to have their feelings touched by these things, to think that human nature is older and more sacred than any claim of property whatever, and that it has rights at least as much to be respected as any hypothetical one of our Southern brethren...
The encroachments of slavery upon our national policy have been like those of a glacier in a Swiss valley. Inch by inch, the huge dragon with his glittering scales and crests of ice coils itself onward ... the relic of a bygone world where such monsters swarmed. We have entire faith in the benignant influence of Truth, the sunlight of the moral world, and believe that slavery, like other worn-out systems, will melt gradually before it," - James Russell Lowell, The Atlantic Monthly, October 1860.

The design was originally adopted as the seal of the Society for the Abolition of Slavery in England in the 1780s, and appeared on several medallions for the society made by Josiah Wedgwood as early as 1787.)
