The hero of The Stranger displays a detachment not only from society, but also from women. He does not cry at his mother’s funeral. He does not sympathize with Raymond’s ex-girlfriend when she is brutally beaten. He does not love his own girlfriend, though he admittedly enjoys her company. Treatment of women is the main theme here, but other romantic and/or sexual relationships in the novel provide additional insights by way of contrast.
Meursault’s actions in and attitude towards his relationship with Marie is representative of his actions and attitudes in general: he is motivated only by the physical and concerned only with himself.
There are no positive examples of sexual relationships in The Stranger. Therefore, Camus argues that, to the absurdist, sex is at best irrelevant, and at worst destructive or hurtful.
