“极化”是现代主义文艺思潮的深层运动形态。在美学理论形态上表现为现代人本主义美学和科学主义美学两股潮流的起伏、摇摆和对峙,但70年代后,有相互渗透、融合的趋势。从“极化”运动来考察,“后现代主义”文艺现象只是现代主义文艺思潮在新的历史条件下的变革与发展,并未形成独立的思潮。 “Polarization” is a deep movement form of modernist ideological trend of literature and art. In the aspect of aesthetic theory, it shows ups and downs, sway and confrontation of the modern humanistic aesthetics and scientifical aesthetics. However, since the 1970s, there is a tendency of mutual penetration and integration. Examined from the “polarization” movement, the “postmodernism” literary phenomenon is only the transformation and development of modernist ideological and artistic trends of thought under the new historical conditions and does not form an independent trend of thought.
