The thirty-three sections of the Chuang Tzu annotated by Kuo Hsiang of the Chin dynasty were published during the period of the Northern Sung dynasty. Meanwhile, a preface allegedly by Kuo Hsiang was also printed in the book. The preface is as follows:Chuang Tzu was a man who had good knowledge of the origins of things in the universe and avoided no fantastic ideas. His remarks are hard to understand yet pertinent to phenomena. Any remark which is hard to understand (...) yet pertinent to phenomena may be true but useless; any remark which touches no actual things may be lofty but impracticable. This is surely different from a reluctant rise after inability. If the mind is free from preoccupations, it will respond to events at any time, and as a result, remarks will be cautious. Adapting himself to changes in the universe, Chuang Tzu was not merely turning out writings in the form of dialogues on things beyond human experience. (shrink)

Comrade Huang Yüeh-mien's article, "A Discussion of the Aesthetics of the Wealthy" [Lun shih-li che ti mei-hsüeh], which criticized my point of view in aesthetics, was published later than my self-criticism. Before he published it, he had presented it at a discussion meeting at Peking Teachers College. He let me read it only after he had submitted it to Literature [Wen-i pao] for publication. I wrote to the editor of Literature, Comrade K'ang Cho, saying that basically I accepted his criticisms (...) but that I wished to raise a number of points. I pointed out that the author's method of dealing with the problems of "empathy emotion," "forgetting self," and "inspiration" was not very different from the method that I had used before. I pointed out that "association of ideas" occupied an important position in his aesthetics — he seems to substitute "association of ideas of form" for "intuition of form." Furthermore, I stated that I did not think he had answered clearly the questions of whether "beauty exists in the mind or in the thing," of the relationship between beauty and sense of beauty, and of the difference between formal thought and abstract thought; and I said that I hoped he would give me more assistance with these questions. However, Comrade Huang Yüeh-mien for the most part ignored the points that I had raised and the questions to which I had sought answers, and he published in Literature the paper that he had presented at Peking Teachers College almost unaltered. Consequently, the questions that I raised concerning Comrade Huang Yüeh-mien's point of view in aesthetics remain unanswered. At that time I still felt that his point of view in aesthetics basically was materialistic, although there were some tendencies in it that raised doubts in my mind. This explains the fact that my judgments on idealist aesthetics remain to be improved. (shrink)

After reading the essays of Mr. Ts'ai and Mr. Chu, I have a few immature opinions. Generally speaking, I feel that in dealing with the errors of their opponents, both Ts'ai I in his criticism of Huang Yüeh-mien and Chu Kuang-ch'ien in his criticism of Ts'ai I are quite accurate and convincing. However, in presenting their own arguments of what is right, both of them are on shaky ground and in error. That is because in one way or another, consciously (...) or unconsciously, they either deny the objective aspect of the existence of beauty or deny the social aspect of the existence of beauty . All of them consider the objective and the social aspects of beauty as being either this or that, as mutually exclusive and irreconcilable opposites. They think that if we acknowledge the social aspect of beauty, we then have to deny the objective aspect, the fact that the existence of beauty does not depend on the subjective conditions of a person ; or if we acknowledge the objective aspect, we have to deny the social aspect, the fact that the existence of beauty depends on the social life of human beings. But in fact it is not like that. On the one hand, beauty cannot be separated from human society; on the other hand, it can have an objective existence which is independent of man's subjective consciousness. It is this question that I shall discuss. (shrink)
