First Debate with Stephen Douglas in the Lincoln-Douglas debates http://www.bartleby.com/251/ of the 1858 campaign for the U.S. Senate, at Ottawa, Illinois (21 August 1858). Lincoln later quoted himself and repeated this statement in his first Inaugural Address (4 March 1861) to emphasize that any acts of secession were over-reactions to his election. During the war which followed his election he eventually declared the Emancipation Proclamation, freeing the slaves in those states in rebellion against the union, arguably as a war measure rather than as an entirely political or moral initiative.
