Abstract: The author holds the view that the campaign to criticize psychologylaunched by Peking Normal University in 1958 was completely wrong inorientation and practice. It was contrary to Chairman Maols instruction"letting a hundred flowers blossom and a hundred schools of thought contend".Some useful lessons must be drawn from this campaign. First, it is importantto promote scientific democracy and adhere to legal system. Second, academicproblems should not be settled as political ones. Third, the roles of intelle-ctuals must be evaluated corretly. The interference and sabotage of Lin Piao and the "gang of four" in thefield of psychology during the Great Cultural Revolution was a continuationand further development of the campaign in 1958.
