Kwame Nkrumah
Axioms of Kwame Nkrumah
(NY: International Publishers, 1969), p. 42.

In our party all are equal regardless of their
race or tribe. All are free to express their views.

have opposed that decision. This we consider and proclaim
to be the truest form of Democratic Centralism--decisions
freely arrived at and loyally executed.
