"There are two antagonistic elements of society in America," Seward had proclaimed, "freedom and slavery. Freedom is in harmony with our system of government and with the spirit of the age, and is therefore passive and quiescent. Slavery is in conflict with that system, with justice, with humanity, and is therefore organized, defensive, active, and perpetually aggressive." Free labor, he said, demands universal suffrage and the widespread "diffusion of knowledge." The slave-based system, by contrast "cherishes ignorance because it is the only security for oppression."
