He had some other quotes that are frequently ignored by those who wish to perpetuate the myth that the Civil War was about slavery.
In his 1860 inaugural address, he said: "I have no purpose, directly or indirectly, to interfere with the institution of slavery in the states where it exists. I believe I have no lawful right to do so, and I have no inclination to do so."
Two years later, President Lincoln wrote: "My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union (Letter to Horace Greeley, August 22, 1862)."
And in 1858 Lincoln had written: "I am not, nor ever have been, in favor of bringing about in any way the social and political equality of the white and black races. I am not, nor ever have been, in favor of making voters or jurors of Negroes, nor of qualifying them to hold office, nor to intermarry with white people. There is a physical difference between the white and black races, which I believe will forever forbid the two races living together on terms of social and political equality."
