On the People's Democratic Revolution explains the basic concepts and the instruments for achieving the Philippine revolution. The program of the people's democratic revolution seeks to realize the basic demands of the people in the political, economic, social and cultural fields in opposition to the semicolonial and semifeudal ruling system of big compradors, landlords and bureaucrat capitalists subservient to foreign monopoly capitalism. The Filipino people and their revolutionary forces have persevered in carrying out the new democratic revolution for more than half a century. They cannot accept the escalating conditions of oppression and exploitation under the semicolonial and semifeudal ruling system in chronic crisis. Sounding stronger than the psywar and gunfire of the oppressors and exploiters is the outcry of the people for national liberation, democracy, social justice and all-round development amid the worsening crises of the semicolonial and semifeudal ruling system and the world capitalist system.
