Zhu Guangqian, a renowned esthetician in Chinese modern history, made an outstanding contribution to Chinese aesthetics by introducing, translating, and popularizing western aesthetics and western literature and art theories into China. Before the liberation, Zhu advocated Benedetto Croce's psychological aesthetics and remained as one of the representatives of Chinese aesthetics in this regard. After the liberation, having experienced a number of political movements such as the Ideological Remolding, the Great Debate of Aesthetics, the Cultural Revolution and the New Period, particularly having encountered enormous political pressure and repeated sieges launched by his academic opponents, Zhu had been compelled to revise and modify his thoughts and theories time after time. At last, Zhu had turned to Karl Heinrich Marx and Giambattista Vico's Humanity Implication for inspiration. However, Zhu was consistent in his unique understanding of the relationship between human nature and aesthetics. During his early period (1929 - 1949) , Zhu implanted his aesthetic thought only in psychological research, while in his later period (1949 - 1986), Zhu was human-centered, apparently reflecting on the issue of Humanity to a deeper level. It is indubitable that the value and contribution of Zhu Guangqian's aesthetic thought in his later period often go underestimated or neglected. If we fail to attain a comprehensive understanding of the founder of modern Chinese aesthetics in terms of his ideological transformations, we would not stand a chance to gain a thorough and profound perception of the development of Chinese aesthetics. This thesis consists of four chapters. Chapter One primarily discusses how Zhu Guangqian broke through the ideologically forbidden zones of "the theory of humanity" and "humanitarianism", and restored "humanity" and "subjectivity" as axiology. Chapter Two analyzes how he constructed the theory that "aesthetics is the unification of subjectivity and objectivity," during the period of the Great Debate of Aesthetics as epistemology to confirm the subject value. Chapter Three discusses, respectively, how Zhu proved the theory that "aesthetics is the unification of subjectivity and objectivity" and the thought of "humanitarianism" through his two-time application of K. Marx's“Economic and Philosophic Manuscripts of 1844.”Chapter Four is mainly concerned with Zhu's methodological inspirations in his creative application of Vico's New Science to "humanitarianism". The thesis, through the substantial analysis, combines historical facts and theories, applies the different perspectives from axiology, epistemology, methodology and creationism, and explores the core of Zhu's aesthetic ideology to seek for the value of human nature, particularly in his later period. This thesis aims to examine how this aesthetic master of his generation always stood firm on the frontline of ideological liberation despite the change of time, and how he made a monumental contribution to the construction and development of the discipline of Chinese Aesthetics in the light of his academic transformation from discovery, cognition to demonstration, and from the establishment of value to comprehensive creation, and how he showed his consistency and steadiness in his belief in the value of human nature and truth.

中國近代美學家朱光潛先生（1896－1986）的傑出貢獻，主要是把西方 美學和文藝理論引入中國，予以翻譯、介紹及傳播。解放前，他主張克羅齊一 派的心理學美學，成為中國美學界的代表人物之一。解放後，經歷「思想改造」、 「美學大討論」、「文化大革命」和「新時期」，面對政治壓力和學術論敵的多 次圍攻，他的思想和理論經過多番自我修正縫補，最終以馬克思和維柯的人學 意蘊為依歸，而他對人性之於美學的獨特見解始終如一。相比前期（1924—1949） 只注重心理學研究的美學觀點，朱光潛後期美學（1949—1986）以「人」為中 心，明顯對人的問題作了更深層次的思考。但無可否認，朱光潛後期美學的價 值和貢獻往往被人們低估和忽視，倘若對近代美學奠基人的思想蛻變缺乏全面 了解，更遑論對中國美學的發展歷程會有透徹認識。 本論文分為四章，第一章主要論述朱光潛如何衝破「人性論」和「人道 主義」思想禁區，作為還原「人性」和「主體性」的價值論。第二章集中論述 朱光潛如何在「美學大討論」時期建構「美是主客觀統一」說，作為肯定主體 價值的認識論。第三章分別論述朱光潛如何兩度利用馬克思《1844 年經濟學－ 哲學手稿》，作為論證「美是主客觀統一」和「人道主義」的方法論。第四章 主要論述朱光潛如何利用維柯《新科學》，作為通向「人道主義」的創造論。 在具體論析中，通過史與論相結合，嘗試從價值論、認識論、方法論、創造論 四個不同的角度探討朱光潛後期美學思想的核心－－尋求美學中的人性價值， 務求藉著朱光潛從認識發現到方法論證、從確立價值到綜合創造的學術蛻變歷 程，和他對人性價值和真理追求的堅定不移，還原一代美學大師是如何久經時 代轉變而仍然站穩在思想解放的前線，為中國美學學科的建構和發展作出不朽 的貢獻。 關鍵詞： 美學 美是主客觀統一 主體 人性 人性論 人道主義 異化 馬克思 維柯 《1844 年經濟學－哲學手稿》 《新科學》 反映論
