Consumer society is a symbolic society, a society controlled by symbols and in which people are symbolized. In consumer society, people' s spirit and belief are structured by consumption ideology, behind which is the concealed capital power. So consumer society is a symbolic society leaded by consumption ideology made by capital.Classroom field of consumer society is influenced and controlled by consumption ideology potentially, but essentially, it is still a story of capital which is happening. Capital hides behind, reconstructs the classroom field secretly, by means of consumption ideology. At the same time, it is showed as education policies and measures in public. Therefore, the classroom field of consumer society has in fact become a slaughterhouse which is symbolizing students and controlled by symbols. Strictly, this kind of classroom field is not carrying on real education, but alienation served for capital. It is making humanity dying away, spirit slaughtered, consciousness hanging, critique deprived, students ravaged, and making people a symbol of nothing.To reveal the essence of classroom field in consumer society, firstly, the report analyses the background and then defines some relative conceptions. Based on these, it interrogates and criticizes the essence metaphysically. The report includes three parts.The first part is made of five chapters, aiming to state and analyze consumer society and classroom field in it. This part discusses the background of classroom field in consumer society, defines consumer society, field, classroom field, symbol, alienation, etc, and expounds the necessity of metaphysical thinking.The second part, including four chapters, aims to deconstruct and criticize consumer society and classroom field in it. In this field, to students, education identity is a kind of symbolic means of existence, culture is a kind of symbolic consumption, knowledge and discourse are a kind of symbolic control, consciousnesses and ideology are a kind of symbolic structuring. In the end, students are structured to be a sort of symbols: the symbol suited for capital's need, the symbol which has lost the real meaning of education, the symbol which has lost human's real spirit and ideal, the symbol which is lifeless and meaningless at all. This part mainly criticizes the mechanism and measure of symbolic structuring, and discloses the evil of concealea capital.The last part, owning two chapters, aims to make a conclusion. Based on the critiques and analyses in nine chapters above, this part raises a series of questions: What is human? What is classroom field of consumer society? What is human in classroom field of consumer society? At last, it draws the conclusion: It is a true lie that human is all-around, free and developing in classroom field of consumer society. It is, and only is a deceivable drumbeating, and it means nothing.In the postscript, the report put forwards a 'possible' possibility, and suggests a little expectation on students' symbolic fate in classroom field of consumer society. Maybe, we still have some 'possible' possibility.
