In Ai Ssu-ch'i is exemplified and substantiated the Soviet influence on the official definition of philosophy in the history of Communist Party of China, i.e., the assertion about and the method for knowledge of the world. Such a philosophical knowledge has as its formal object the most fundamental laws of the universe.In order to acquire such a genuine philosophical knowledge, one needs a desire to change the world and a proletarian point of view. For only by aiming at changing the world is inevitability reflected; only in the proletarian viewpoint are the objective laws reflected. In order to substantiate these assertions, one has to point out that, first, man's thinking is determined by his social relations (economic relationships) and, secondly, social relations are determined by practice. Since the proletariat is in the right kind of practice, it is both in the proper locus of social relations and, therefore, it perceives both inevitability and objectivity. Yet, due to man's subjective dynamism, it is possible for other classes to adopt the standpoint of the proletariat.
