遗传决定论与环境决定论作为自然主义文学最突出的两大典型特征,在约翰·斯坦贝克的自然主义文学小说《伊甸之东》中得到了充分的阐释和论证。虽然该小说在阐述众多人物在选择与追求符合自己自由意识的伊句园与命运抗争时最终失败,但是小说中所流露出的浪漫主义和乐观主义成分不仅不与自然主义相冲突,反而对比加强了文本中的自然主义倾向,使小说具有独特的文学特色。 Genetic determinism and environmental determinism, as two prominent features of naturalistic literature, are fully explained and argued in John Steinbeck’s naturalistic literary novel Eden’s East. Although the novel failed to endorse the struggle of many people in choosing and pursuing their own freedom consciousness, the romanticism and optimism elements revealed in the novel not only do not conflict with naturalism, but strengthen and contrast The tendency of naturalism in the text makes the novel have unique literary features.
