Mao Zedong quotes - page 7
Within the ranks of the people, democracy is correlative with centralism and freedom with discipline. They are the two opposites of a single entity, contradictory as well as united, and we should not one-sidedly emphasize one to the denial of the other. Within the ranks of the people, we cannot do without freedom, nor can we do without discipline; we cannot do without democracy, nor can we do without centralism. This unity of democracy and centralism, of freedom and discipline, constitutes our democratic centralism. Under this system, the people enjoy extensive democracy and freedom, but at the same time they have to keep within the bounds of socialist discipline.
Mao Zedong
