* Pragmatism: Stanley represents the harsh realities of life, contrasting with Blanche's romantic ideals. He acts as a voice of reason, cutting through Blanche's illusions.
* Observation: He is perceptive and keenly aware of the characters' motivations and weaknesses. He sees through Blanche's facade and calls her out for her lies and manipulations.
* Judgement: He makes pronouncements about the characters and their actions, offering his perspective on their behavior.
While not a traditional raisonneur, Stanley's character serves as a counterpoint to Blanche, revealing the flaws in her romanticism and ultimately contributing to her downfall. He represents the brutal realities of life that Blanche tries to escape, acting as a catalyst for her tragedy.
It's also important to note that the play's setting itself can be seen as a collective raisonneur. The humid, oppressive environment of New Orleans reflects the characters' internal conflicts and anxieties, contributing to the play's overall sense of doom.
In essence, "A Streetcar Named Desire" doesn't have a singular raisonneur, but rather several elements working together to highlight the play's themes and drive the narrative forward.
