“History has an ebb and flow of justice, but history also has a visible direction set by liberty and the author of liberty. When the Declaration of Independence was first read in public and the Liberty Bell was sounded in celebration, a witness said, "It rang as if it meant something." In our time it means something still. America, in this young century, proclaims liberty throughout all the world and to all the inhabitants thereof. Renewed in our strength — tested, but not weary — we are ready for the greatest achievements in the history of freedom.”

Context: By a plan known only to Providence, the stolen sons and daughters of Africa helped to awaken the conscience of America. The very people traded into slavery helped to set America free. My Nation's journey toward justice has not been easy, and it is not over. The racial bigotry fed by slavery did not end with slavery or with segregation. And many of the issues that still trouble America have roots in the bitter experience of other times. But however long the journey, our destination is set: liberty and justice for all.

Context: What do we mean when we say that first of all we seek liberty? I often wonder whether we do not rest our hopes too much upon constitutions, upon laws and upon courts. These are false hopes; believe me, these are false hopes. Liberty lies in the hearts of men and women; when it dies there, no constitution, no law, no court can save it; no constitution, no law, no court can even do much to help it… What is this liberty that must lie in the hearts of men and women? It is not the ruthless, the unbridled will; it is not the freedom to do as one likes. That is the denial of liberty and leads straight to its overthrow. A society in which men recognize no check on their freedom soon becomes a society where freedom is the possession of only a savage few — as we have learned to our sorrow.
What then is the spirit of liberty? I cannot define it; I can only tell you my own faith. The spirit of liberty is the spirit which is not too sure that it is right; the spirit of liberty is the spirit which seeks to understand the minds of other men and women; the spirit of liberty is the spirit which weighs their interests alongside its own without bias; the spirit of liberty remembers that not even a sparrow falls to earth unheeded; the spirit of liberty is the spirit of Him who, near two thousand years ago, taught mankind that lesson it has never learned, but has never quite forgotten; that there may be a kingdom where the least shall be heard and considered side by side with the greatest.

Address in Baltimore, Maryland http://www.presidency.ucsb.edu/ws/?pid=88871 (18 April 1864)
1860s
Context: 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 labor; 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 labor. 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.
