Though a concern with nature is one way of accessing the fictional world of all Hawthorne's Transcendentalist contemporaries, he has long been considered the least interested in nature. Despite the vast research done on Hawthorne's rich and multi-layered novel, The Scarlet Letter (1849) has been overlooked ecocritically. Nature/ Culture dichotomy is being overlooked in Hawthorne's work. The goal of this paper is to advance an understanding of Hawthorne's attitude towards Culture/Nature dichotomy through rereading The Scarlet Letter and to derive ethical concepts out of nature. To convey his ecological vision, Hawthorne juxtaposes wild nature against the city of Boston and all that the urban culture stands for in 1750. Through the pastoral experience of Hawthorne's heroine, he rediscovers the natural landscape his ancestors once possessed and discarded as a secluded location of secret desires and moral absence. Exploring the interdisciplinary nature of Ecocriticism to the pastoral mode permits a reconsideration of nature/culture relationship. Hawthorne employs his pastoral heroine to resolve the root tensions between culture and nature by living in the borderline between them, gaining wisdom through her long years of solitude. Connecting the interdisciplinary nature of ecocristicsm together, the paper shows that the values expressed in the text are consistent with the ecological wisdom through psycho-analyzing Hawthorne's main characters. Hawthorne, as a green writer, seeks to promote a reconsidering of one's beliefs and one's vision of Nature for a sound awareness and an essential unity of life
