From an Address at a Sanitary Fair in Baltimore. April 18, 1864

... The world has never had a good definition of the word "liberty," and the American people, just now, are much in want of one. We all declare for liberty; but in using the same word, we do not all mean the same thing. With some, the word "liberty" may mean for each man to do as he pleases with himself and the product of his labour; while with others, the same word may mean for some men to do as they please with other men and the product of other men's labour. Here are two, not only different, but incompatible things, called by the same name,—liberty. And it follows that each of the things is, by the respective parties, called by two different and incompatible names,—liberty and tyranny.

The shepherd drives the wolf from the sheep's throat, for which the sheep thanks the shepherd as his liberator, while the wolf denounces him for the same act as the destroyer of liberty, especially as the sheep was a black one. Plainly, the sheep and the wolf are not agreed upon a definition of the word "liberty;" and precisely the same difference prevails to-day, among us human creatures, even in the North, and all professing to love liberty. Hence we behold the process by which thousands are daily passing from under the yoke of bondage hailed by some as the advance of liberty, and bewailed by others as the destruction of all liberty. Recently, as it seems, the people of Maryland have been doing something to define liberty, and thanks to them that, in what they have done, the wolf's dictionary has been repudiated.
