1860s, Speech in Independence Hall (1861)
Context: I have never had a feeling politically that did not spring from the sentiments embodied in the Declaration of Independence. I have often pondered over the dangers which were incurred by the men who assembled here and adopted that Declaration of Independence; I have pondered over the toils that were endured by the officers and soldiers of the army, who achieved that Independence. I have often inquired of myself, what great principle or idea it was that kept this Confederacy so long together. It was not the mere matter of the separation of the colonies from the mother land; but something in that Declaration giving liberty, not alone to the people of this country, but hope to the world for all future time. It was that which gave promise that in due time the weights should be lifted from the shoulders of all men, and that all should have an equal chance. This is the sentiment embodied in that Declaration of Independence.
