| Human is facing a series of environmental problems, social problems, no doubt it related with traditional view of single subjectivity established by human being self. The topic of modern philosophy transformed from object to subject, rational creative MAN becoming the center and forming the logic frame of subject-object. Single subjectivity is both the basic feature and the basic drawback of the philosophy. The mode of pure subject-object or subject- medium-object makes a lot of problems when dealing with the relations of man and society, man and nature. On one hand, instrument rationality is developing at an unprecedented rate, so single subjectivity and anthropocentrism reaches the extreme; on the other hand, value rationality is weakening and man is becoming alien,twisted and one-dimensional. Inter-subjectivity is the intrincical quality between subjects i.e.in subject-subject mode, which deals with the relations of person and others, person and society, individual and collective. It involves two or more than two subjects, so it transcends the mode of subject-object. The emphasis of subject-subject different from the relation of subject- object is a kind of new thinking and method. The transformation of inter-subjectivity, is from epistemology to linguistics, from single subjectivity to inter-subjectivity, it's a speech revolutionary to extricate from subjective predicament. Language is the home of existence, but is not existence itself; conversation is part of our life world, but first of all man lives in social practice. Language, conversation as a kind of spiritual communication, derives from communication practice. In communication practice, communication and practice can not be separated. The basic dimension of communication practice is not pureobject, not single subject, even not simple inter-subject, it's a synthetical structure of subject-object-subject, is a kind of objective communication activity. Communication practice includes subject-object and subject-subject two aspects and their intercourses, which is the synthesis of subjectivity and inter-subjectivity, is the base of spiritual communication and speech communication, Marx's ideology of communication practice is a spiritual weapon to remake and change the existing alien society. The outlet of subjective problems is the all-sided development of human and sustainable development of environment. |
