How does Tennessee Williams suggest that Blanche is being ‘torn away’ from her ‘chosen image’ within Scenes 7 and 8?
The playwright Tennessee Williams effectively suggests that Blanche is being ‘torn away’ away from her chosen image through the use of language, form, and structure, hence creating and building tragedy. Williams builds this climax of Blanche being ‘torn away’ from her chosen image within scenes 7 and 8, which I will be exploring, such as: the use of form, e.g- the main features of Arthur Miller’s ‘modern domestic tragedy’ and how Williams portrays this within scenes 7 and 8 in relation to Blanche. The fact that ‘A Streetcar Named Desire’ is a play is very effective in regards to portraying this idea of displacement, the reason being, the play is a dramatic genre.
