Slavery has been fruitful in giving itself names. It has been called "the peculiar institution," "the social system," and the "impediment."... It has been called by a great many names, and it will call itself by yet another name; and you and I and all of us had better wait and see what new form this old monster will assume, in what new skin this old snake will come forth next.
