Abstract
The Wang-Chang-Chiang-Yao counterrevolutionary "Gang of Four" carried out revisionism, sowed seeds of discord and resorted to intrigues and plots in an attempt to usurp the Party, seize power, and restore capitalism. Ambition is the source of hypocrisy and falsehood and, of course, of the hypocrisy and falsehood of metaphysics and idealism. The more audacious the "Gang of Four's" ambition to usurp the Party and seize power became, the more barefaced its manifestation of metaphysics and idealism was. Metaphysics and idealism were the faulty ideological weapons they used in the attempt to usurp the Party and seize power. We must follow Chairman Mao's teachings to liquidate the "Gang of Four's" counterrevolutionary revisionist political and ideological line and its crime of impudently trampling on Marxist-Leninist philosophy and Chairman Mao's glorious philosophical thought and protect the purity of Marxism
