A Disease in the Public Mind: A New Understanding of why We Fought the Civil War | 
Jefferson in 1820 on the rift between Republican and Federalist regarding sectionalism:
“The coincidence of a marked principle, [both] moral and political...would never more be obliterated from the [public] mind...it would be recurring on every occasion until it would kindle such mutual and mortal hatred as to render secession preferable to eternal discord.“ p. 93
Rather seems as though we are still having the same conversation 200 years later.
