本文以李长之20世纪30年代、40年代与50年代三大阶段的学术思想发展为纵向线索,重点以其对中西浪漫主义思想的考察为主线,探讨其在三大领域展开的学术研究。分别是鲁迅批评及其他现代作家作品批评,古代先贤传记批评与古典文学及文化研究,对德国学术思想史与作家作品的译介、接受及对其文论再创的启示。 This paper takes Li Changzhi’s academic thoughts of the three stages of the 1930s, 1940s and 1950s as the vertical clues and focuses on the investigation of the romantic ideas between China and the West to discuss its academic research in three major areas. They are respectively the criticisms of Lu Xun and other modern writers, the criticism of ancient sages, the study of classical literature and culture, the translation and acceptance of the history of German intellectual history and the works by writers, and the revelation of their creation.
