The shepherd drives the wolf from the sheep’s throat, for which the sheep thanks the shepherd as a 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.

-Abraham Lincoln
