Abstract

There has long been theoretical confusion caused by the "gang of four" and the counterrevolutionary clique led by Lin Piao. They are responsible for the rampancy of metaphysics and idealism in handling the question of the criterion of truth. The "gang of four" gave the pragmatist outlook on truth wide publicity, spoke up for the usefulness of truth, negated the criterion of practice in the test of truth, and repudiated the absoluteness of the criterion of practice. The group also carried out absolutism, denied the development of human knowledge to the accompaniment of the development of practice, and negated the absoluteness of the criterion of practice. Therefore, a correct elucidation of the relativity and absoluteness of the criterion of practice is necessary for the elimination of the theoretical confusion caused by the "gang of four" and of its baneful effects
