“The paradox of calling the same human beings persons and property brings the cause of the Civil War into the sharpest focus. A person by definition is a being possessed of a rational will. A chattel by equal definition is a piece of movable property without a rational will. Because a horse or a dog lacks a rational will, its owner is responsible for any damage or injury it may cause. But slaves were held as responsible for their own actions, as were their masters, under the criminal codes of the slave states. The slave owners, in seeking to have the slaves counted as five-fifths, were asserting that they were full human beings. At the same time, by claiming the right to their labor as chattels, they were asserting them to be sub-human. How the slaves could be both was something that Jefferson Davis and his friends never explained.”

Context: If "freedom" means, first of all, the responsibility of every individual for the rational determination of his own personal, professional and social existence, then there is no greater fear than that of the establishment of general freedom. Without a thoroughgoing solution of this problem there never will be a peace lasting longer than one or two generations. To solve this problem on a social scale, it will take more thinking, more honesty and decency, more conscientiousness, more economic, social and educational changes in social mass living than all the efforts made in previous and future wars and post-war reconstruction programs taken together.

Context: The Declaration of the causes and Necessity of Taking up Arms, on July 6, 1775, was the very first occasion for the American people to speak to the world with a single voice. In its first sentence, the Second Continental Congress affirmed without equivocation that the idea of the ownership of some human beings by other human beings was an utter absurdity, and that to think otherwise was incompatible with reason or revelation. Thus from the outset—a year before the Declaration of Independence—the American people were committed to the antislavery cause, and to the inseparability of personal freedom and free government. The American people knew from the outset that the cause of their own freedom and that of the slaves was inseparable. This would become the message that Abraham Lincoln would bring to the American people, and to the world, for all time.
