“Whenever one seeks to overthrow a regime, it is always necessary first to carry out ideological work” [1] (September 1962). Whenever one seeks to overthrow a regime, it is always necessary first to create public opinion; it is always necessary first to engage in ideological work. This holds true both for revolutionary classes and for counterrevolutionary classes. Printed according to the Decision of the Central Committee of the Communist Party of China on the Proletarian Cultural Revolution (adopted on August 8, 1966). Note [1]: This is an excerpt from a speech delivered by Mao Zedong at the Tenth Plenary Session of the Eighth CPC Central Committee in September 1962.
