Near the end of the trial in The Stranger, Meursault is asked why he fired the gun. He has been through the questions — the vigil, the coffee, the comedy film, the beach — and now the court wants the thing at the center: the act itself. Why did you shoot? He has no answer that satisfies. He says, briefly and without apparent calculation, something about the sun.
The courtroom laughs.
The laughter is not unreasonable. “Because of the sun” is not a legal defense. It is not a moral explanation. It does not fit any of the available categories — premeditation, accident, self-defense, temporary insanity. It sounds like deflection, like a man who cannot or will not account for himself reaching for the most convenient nearby object to blame. The court hears it as an evasion and moves on.
But consider the possibility — and I want to hold this open seriously, not as a provocation — that Meursault is telling the truth. That “the sun” is the most accurate available description of what happened on the beach. That the courtroom’s laughter is the sound of a legal system encountering a claim it has no apparatus to process.
Meursault’s account of the beach, in the novel’s first part, is among the most carefully observed passages in The Stranger. He describes the heat with unusual precision — not as atmosphere but as physical force. The sun presses down. The light bounces off the sand and the water until it is everywhere at once, coming from below as well as above. The air itself seems to have weight. Moving through it requires something more than normal effort. Sweat films over his face and runs into his eyes.
In the moment before the shooting, the description becomes almost clinical. His vision blurs. The glare is so intense that objects at the edge of his sight begin to waver. The Arab’s knife catches the sunlight and reflects it directly into his eyes — a flash of light that Meursault experiences as physical impact, as though the sun has struck him. He loses, for a moment, clear perception of where he is and what is happening.
Read without the interpretive frame of existentialism or colonial allegory, this passage describes the early symptoms of someone whose body is failing to cope with extreme heat. The headache, the visual disturbance, the disorientation, the sense that effort and environment have outpaced the body’s capacity to compensate — these are recognizable features of heat exhaustion. Meursault is not philosophically overwhelmed. He is physiologically overwhelmed. The distinction matters enormously, and the trial never makes it.
Albert Camus grew up in the working-class Belcourt neighborhood of Algiers, the son of French settlers. The city sits on the Mediterranean coast, under a sun that in summer months creates an environment quite different from anything a reader in Paris or London or New York would be likely to encounter. The Algerian noon in July is not a literary device. It is a bodily fact — a specific quality of light and heat that anyone who has experienced it carries in their skin.
Camus did not research the sun’s effect on Meursault’s consciousness. He remembered it. The sun in The Stranger is drawn from physical memory, not from literary convention. When critics write about the sun as a symbol of the absurd or of fate, they are reading the novel from a cool room. What Camus wrote comes from someone who knew what it was to stand on an Algerian beach in July and feel the afternoon become physically untenable.
This matters for how we read the beach scene. The novel’s French readers in 1942, reading in Paris, may have understood “the sun” as metaphor. The readers who have experienced that specific climate — the particular quality of light and heat that Camus is describing — may read it differently. They may read it as testimony.
Meursault, when he says “because of the sun,” is not reaching for a philosophical abstraction. He is reaching for the most immediate material fact of his experience. The sun was there. The sun was the dominant presence on that beach. The sun was doing something to his body that his body could not fully absorb. This is what he means. He does not have a better word for it, and neither does the law.
Consider what the sun actually does in the scene of the killing.
Meursault has already turned back from the beach once — he walked Raymond and Masson back to the bungalow and returned to the bungalow himself. He goes back to the beach in the afternoon because he cannot stay in the bungalow. The heat inside is equivalent to the heat outside, and there is something about the light, the movement, the sensory density of the beach that draws him back even in conditions that are clearly becoming too much for him to manage comfortably.
At the rock, the Arab is waiting — or not waiting, exactly, but simply present, in the shade. Meursault approaches not because he intends confrontation but because the shade is there, and the spring that runs into the sand, and the relief from the sand’s reflected heat. He moves toward the coolness. The Arab is in the way.
The Arab draws the knife. The knife catches the sun. The light bounces into Meursault’s already-compromised eyes. The sweat runs over his face. And then: the gun fires.
Meursault does not decide to fire the gun. He does not calculate. He does not weigh consequences. Between the flash of reflected light in his eyes and the sound of the shot there is no deliberate act. There is the body, overwhelmed, responding. The gun is in his hand — Raymond gave it to him hours ago, and he forgot to return it, because in the heat he is not tracking things with his usual economy of attention. The gun fires.
The sun is not a symbol in this scene. It is a collaborator. It dries out Meursault’s eyes, creates the visual disturbance that makes the moment before the shooting uncertain and dreamlike, heats the air to the point where simply being on the beach is already more than the body wants to sustain, and at the crucial instant it redirects off the knife blade and into his face. The sun participates in the killing. This is what Meursault is saying when he says “because of the sun,” and it is true.
The court calls the care home director, the vigil attendants, Raymond, Marie, Masson, Salamano, Céleste, Pérez. It does not call the one participant in the events of July that Meursault himself identifies as causal. The sun is the only witness Meursault names. It is not in court.
Now I want to apply some pressure to the reading I have been building.
If we take the physiological account seriously — if we read Meursault’s “because of the sun” as a genuine, if inarticulate, description of bodily overwhelm — then we are constructing a defense that locates the responsible Meursault somewhere outside the scene on the beach. The cool Meursault, the indoor Meursault, the Meursault sitting in shade with a glass of water would not have shot the Arab. The heat-compromised, sweat-blinded, physiologically failing Meursault on the July beach did. The defense implies: who Meursault is when he is not overwhelmed by the sun is who he really is, and who he really is would not do this.
But I am not sure this is right.
The Meursault on the beach is also Meursault. The embodied, suffering, sweating, sun-overwhelmed person who pulls the trigger is not a distorted version of the real Meursault from whom the sun briefly separates him. He is Meursault, fully present, responding to the conditions he is actually in rather than the conditions a cool legal philosophy would prefer him to be in. To build a defense from the sun is to claim that Meursault’s responsible self and his beach self are different entities — that the body, when overwhelmed, becomes something other than the person. The law shares this fiction: the legally responsible subject is always, implicitly, a cool deliberating agent whose body does not intrude on its reasoning. This is why the court laughs at “because of the sun.” The sun is inadmissible because the law’s model of the responsible agent has no slot for it.
But there is a further problem that the essay has been avoiding.
The sun was on the Arab too.
Whatever the sun was doing to Meursault’s body on that beach — the heat exhaustion, the visual compromise, the disorientation — it was doing to the Arab in the same afternoon. The Arab was also in July, also on an Algerian beach, also under the direct force of what Meursault experienced as physically overwhelming. The sun as defense is a defense that places the agent in an environment so extreme that normal deliberation cannot operate — and then applies this defense only to one of the two people present. Meursault was overwhelmed by the sun. The Arab was also overwhelmed by the sun. The essay has been building a physiological account of Meursault’s state and has not asked what the same conditions were producing in the man who was killed.
The sun doesn’t belong only to Meursault’s defense.
What the trial cannot incorporate — and what “because of the sun” exposes about the trial’s limits — is the body as a genuine factor in human action. The legal system’s model of responsible agency requires what we might call the cool deliberating subject: a person who reasons through their choices in something like a climate-controlled interior, unaffected by the conditions of their body or their environment. This is not how bodies actually work. Bodies are affected by temperature, by hunger, by exhaustion, by pain, by the accumulated stress of an afternoon that has already included a knife fight and a coastal walk in direct sun. The body imposes itself on the subject who is supposed to be doing the deliberating.
Meursault’s defense, had it been taken seriously, would have required the court to incorporate this bodily reality into its model of responsibility. Not as an excuse that removes responsibility entirely — “the sun made me do it” does not mean Meursault bears no relationship to the act — but as a genuine factor that complicates the picture of premeditation and cold intentionality that the prosecutor constructs. A man in the early stages of heat exhaustion who fires a gun when a knife catches the light in his already-compromised eyes is not the same as a man who plans, deliberates, and executes. The act is the same. The actor is meaningfully different.
The court cannot make this distinction because its model of responsible agency requires a subject who is always, in principle, capable of deliberation. Bodies are an inconvenience to this model, which is why criminal law addresses them mostly at the extremes — full incapacity, medical insanity — and not in the middle ground where Meursault lives: conscious, present, capable of normal function, but not, in that specific afternoon, capable of the cool deliberation that the legal concept of premeditation requires.
Meursault says “because of the sun” and the courtroom laughs. The laughter is the sound of a system encountering a claim that does not fit its categories. The claim is not that the sun is responsible and Meursault is not. It is that what happened on the beach cannot be adequately described by the available legal vocabulary — that premeditation requires a cool deliberating subject and Meursault on that beach was not one.
This is true. It is also legally useless. If “the sun” were accepted as a mitigating factor in violence, the consequences would be unmanageable: every act of violence in a hot climate could claim the same defense, and the law would have no way to distinguish degrees of bodily overwhelm. The court laughs not only out of contempt for Meursault but out of a genuine recognition that this is not an argument the law can absorb.
The question the novel leaves open is not whose account is true — Meursault’s (the body overwhelms the will under certain conditions) or the law’s (the will controls the body and is always capable of deliberation). Both are partially true. Both are distortions.
The question is whose distortion we are willing to make lethal. The law chose its own. The courtroom stopped laughing and delivered the verdict.
The Stranger does not tell us whether this was correct. It simply records that the body on the beach and the body in the dock are the same body, and that neither account — the bodily one, the deliberative one — is adequate to explain what that body did on a July afternoon in Algiers, when the sun was already past bearable and still climbing.
