Isaac Asimov didn't just write about robots; he wrote about the walls we build around ourselves. Honestly, when people talk about the Robot series, they usually gravitate toward the sleek logic of I, Robot or the gritty, overpopulated corridors of The Caves of Steel. But The Naked Sun is where things get weird. It’s where the series gets uncomfortable. Published in 1957, this sequel to the detective-noir setup of the first book takes Elijah Baley—a plain-clothes detective from a claustrophobic, underground Earth—and throws him onto a planet where people literally cannot stand to be in the same room as one another.
Solaria is a nightmare.
Imagine a world where "viewing" (basically 3D video calls on steroids) is the only acceptable way to socialize. Physical contact? That’s "seeing." And it’s considered disgusting. Visceral. Perverted. If you think our modern obsession with remote work and Zoom fatigue is a new phenomenon, reading The Naked Sun in 2026 feels like someone reading your diary from seventy years ago.
The Impossible Murder on a World of Hermits
The plot kicks off because a man has been murdered on Solaria. That shouldn't be possible. On a planet with a population of only 20,000 humans (and millions of robots), everyone lives on massive estates miles apart from their nearest neighbor. They never meet in person. So, how do you bludgeon someone to death when no one was within fifty miles of the victim?
Enter Elijah Baley.
He’s still terrified of the open sky. Coming from Earth—a world where billions of people live packed like sardines in "Cities"—the sheer emptiness of Solaria is a psychological horror show for him. He’s paired up again with R. Daneel Olivaw, the humanoid robot who looks like a god and thinks like a calculator. Their dynamic is the heart of the book, but the real star is the societal decay of the Solarians themselves.

The victim is Rikaine Delmarre, a "fetal engineer." His wife, Gladia, is the prime suspect. But she couldn't have done it, right? Because that would involve being in the same room as him. The taboo is so strong that Solarians actually experience physical illness—fainting, vomiting, panic attacks—at the mere thought of "seeing" another human.
Why Asimov’s Sociology Still Stings
Asimov was a master of the "locked room" mystery, but The Naked Sun is more of a "locked soul" mystery. He explores how technology doesn't just assist us; it defines our boundaries. On Solaria, robots do everything. They farm, they cook, they clean, they mine. This has led to a stagnant, decadent culture where humans have lost the ability to even be human.
Think about it.
The Solarians aren't just introverts. They are evolutionary dead ends. By outsourcing every physical task and every social interaction to a robotic or digital interface, they've surrendered their resilience. Asimov is poking at a very specific fear here: the idea that as we become more technologically "connected," we become biologically and emotionally isolated.
There’s a scene where Baley tries to explain Earth to a Solarian. The Solarian is horrified by the idea of people touching, breathing the same air, or—heaven forbid—smelling each other. To a Solarian, Earth is a hive of filth. To Baley, Solaria is a graveyard of the living. It's a brilliant clash of two extremes. Earth is the extreme of over-socialization and lack of privacy, while Solaria is the extreme of hyper-individualism and total isolation.

The Three Laws and the Loophole
You can't talk about The Naked Sun without mentioning the Three Laws of Robotics. It's the bread and butter of Asimov's universe.
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
In this book, the mystery hinges on how these laws can be subverted. If a robot is told to put a certain chemical in a glass of water, it does so. It doesn't know it's poison. If another robot is told to give that glass to a human, it does so. Neither robot has "injured" a human. The "harm" was fragmented across multiple machines. This is a terrifyingly relevant concept in the age of algorithmic bias and distributed AI systems. When no single entity is responsible for the final outcome, who do you blame for the "murder"?
The Gladia Factor
Gladia Delmarre is one of Asimov's more complex female characters, especially for the 1950s. She’s trapped in a culture that treats her like a delicate, isolated flower, yet she possesses a repressed vitality that scares the people around her. Her relationship with Baley is fascinating because it’s built on a mutual breaking of taboos. When they finally "see" each other (and eventually, in later books, more), it’s an act of rebellion against a sterile society.
She represents the bridge between the two worlds. She wants to feel, even if feeling hurts. Solaria, as a planet, has forgotten how to hurt, which means it has forgotten how to grow.
The Legacy of the "Naked" Sun
The title itself is a bit of a double entendre. It refers to the literal sun, which the Earth-dwelling Baley finds terrifyingly "naked" and exposed. But it also refers to the exposure of the soul. On Solaria, everything is hidden behind screens and robots. To be "naked" is to be vulnerable, to be in the presence of another.

The book ends with a realization that is pretty bleak for the Solarians but hopeful for humanity. Baley realizes that Earth needs to change. The "Caves of Steel" are a dead end, but Solaria is a different kind of tomb. The middle ground—the "Outer Worlds"—might be the only way forward.
This isn't just a detective story. It's a warning about the comfort of silos.
How to read The Naked Sun today
If you’re looking to dive into this classic, don’t just treat it like a dusty relic. It’s a fast-paced thriller that happens to have a high IQ. Here is how to get the most out of the experience:
- Read "The Caves of Steel" first. You need the context of Baley’s claustrophobia to understand why the emptiness of Solaria is so jarring.
- Pay attention to the robots. Don't just view them as appliances. Look at how they reflect the specific neuroses of the Solarian people.
- Watch for the foreshadowing. Asimov was setting up the Foundation series here, even if he didn't fully realize it yet. The "Spacers" (the people of Solaria and other worlds) are the architects of their own eventual irrelevance.
- Consider the "Viewing" vs. "Seeing" metaphor. Apply it to your own life. How much of your "socializing" is viewing? How much is seeing? It's a legitimate gut check.
Ultimately, The Naked Sun remains one of the most poignant entries in the Asimov canon because it asks if we are willing to trade our humanity for total safety and convenience. The answer, in Solaria’s case, is a resounding and chilling "yes."
To really grasp the scope of what Asimov was doing, your next move should be looking into the Robot/Foundation synthesis. Specifically, check out Robots and Empire, which takes the Solaria concept to its logical, horrifying conclusion centuries later. Understanding the fall of the Spacers is the key to understanding why the Galactic Empire had to exist in the first place.
