在现代西方文论各流派中,形式主义无疑占据着举足轻重的地位,并对中国的文论思想产生很大影响。但对于什么是“形式”这一核心概念,无论是在西方还是中国,都始终是众说纷纭,莫衷一是。本文试图通过厘清“形式”的概念,指出“形式”是理解现代西方文论的钥匙,“形式”的概念从未从现代西方文论史中消失。它的语言—诗学本质对后续的各流派产生了链式的影响,对当代文论思想的细化、拓展和发展做出了重要贡献。 Among the schools of modern Western literary theory, formalism undoubtedly occupies a pivotal position and exerts a great influence on the ideology of literary criticism in China. However, there is no consensus on what constitutes the core concept of “form”, whether in the West or in China. By clarifying the notion of “form”, this paper attempts to point out that “form” is the key to understanding modern Western literary theory. The concept of “form” has never disappeared from the history of modern western literary theory. Its language - the poetic nature has a chain effect on the follow-up schools and makes important contributions to the refinement, expansion and development of contemporary literary theory.
