“第三自然界”理论对文艺本性和特征作出极富开拓意义的阐述,启发我们把文艺看作是与社会生活既同一又分离的整体。这一性质使得文艺成为社会生活的表现形式(本体性形式),因而具有审美性;同时,文艺又有自己的表现形式(技术性形式)和内容。文艺的内容由于同社会生活的内容有同一性,所以既是审美的,又是可以具有功利性的。 The theory of “Third Nature” makes a very pioneering exposition on the nature and characteristics of literature and art, inspiring us to regard literature and art as both an identical and separate entity with social life. This nature makes literature and art a manifestation (the noumenal form) of social life and thus aesthetic; at the same time, literature and art has its own form of expression (technical form) and content. Since the content of literature and art is identical with the content of social life, it is both aesthetic and utilitarian.
