Civil Disobedience is Thoreau's argument for the deliberate violation of laws for reasons of
conscience. Thoreau's concept is based on the belief that no law should command blind obedience, and that
non-cooperation with unjust laws is both morally correct and socially beneficial.

The Liberator was a leading voice for abolitionism in the nineteenth century. Abolitionism called for the immediate
emancipation of slaves, based on the principle that individuals own their bodies, labor, and the fruits of their labor.
Abolitionists vigorously opposed gradualists, who called for phasing out slavery over a long period of time; they also
opposed colonizationists, who wished to relocate former slaves to another country.
