This essay attempts to prove that Blanche is much more than just "a victim of neurosis," an alcoholic, a debauched seducer of young boys, and a "faded Southern belle" who just pathetically clings to the decayed values of the decadent old South as some critics claim. Rather her behavior, her state of mind, her way of thinking, her style of doing things, and her social manner all show signs of the culture of the old South. All what Blanche represents and what she attempts to protect and preserve are positively presented as the genteel values of the old Southern civilization even though it has physically "gone with the wind." But surprisingly critics neither have said anything about Blanche being "the strongest" character in the play, nor have mentioned anything abut "Blanche being the most rational of all the characters [Williams has] created," let alone explore her active role in defending, preserving and recreating the past genteel values of the old Southern civilization in her cultural war against the relentlessly brutal modern society represented by Stanley. Thus in this essay, I will argue that consciously or unconsciously Blanche not only attempts to live in the past in her so-called "illusions," but also pertinaciously clings to the genteel values of the old South, tenaciously fights for their survival and actively recreates them whenever she has an opportunity. Although Williams recognizes that the naturalistic realism of the modern society necessarily requires that Blanche be physically, socially and politically beaten in the ruthless reality of the modern society, he sympathetically suggests that spiritually, Blanche's cultural war is not completely futile, at it has indeed left its potential marks in the world even after she leaves.
