I reread this novel for the fourth time after a long hiatus. I remember the previous times it flew seamlessly and I liked the fluent narration with a tang of indifferent air. However, on second thought, I felt there were more glitches in the analytical view of the plot and the protagonist's character. This was especially more curious since the author has the kingpin status in 20th-century existentialism. I found it very paradoxical and inconsistent if you want to take notes in existential terms:
The existentialism philosophy seems to redefine human existence with an emphasis on individual responsibility and excluding the metaphysical approach to human problem. The caricaturesque protagonist in The Stranger is anything but an accountable persona who shows awareness or anxiety of those in existential limbo. In other words, this is not a philosophical indifference distilled through soul-searching and spiritual endeavors. Meursault's stance regarding love, family, faith, death, daily life, job, food, sex, hobbies, and even climate (he loves and eventually misses the Mediterranean climate), all picture a plainly simple mindset devoid of perspective. The plot pictures a series of random spontaneous actions that are devoid of meaning from the protagonist's point of view. That is not the existential disdain following epistemic labor routes.
Meursault decides to give false testimony in support of a corrupt neighbor, passively accepts a marriage offer, and finally commits a murder in a confused haze with no clear intention. All events in the story are lined up with zero conviction.
In flashbacks and in his mother's words, Meausault is described as a child/adolescent who was able to create happiness for himself, so he is not unhappy. He suffers from an existential anomy but a lazy type of anomy. Philosophy, ethics, faith, social or individual issues are not of interest to him as far as we learn. He is not bound to the truth as well. So it's basically downright flattened spirit as far as character study goes.
When questioned about his motives for killing the victim, he seriously mentions "the heat/the sun" caused him toward this crime. This is a masterpiece in absurdism but a preload to the existentialism line of thought, Camus pursues in the successive work "The Myth of Sisyphus". The Stranger as a stand-alone work, is a short story of a lost soul in a confused chorea of meaningless actions. Hard to say it is anything but a sad portrait of confused pointless state of affairs in human life, or at least this is what the author wants to say.
