Solaris by Stanisław Lem: the alien we cannot understand

Solaris is Stanisław Lem’s 1961 novel about a research station above a planet covered by a living ocean, and a psychologist who arrives to find the station and its crew coming apart. It is not really a first-contact story. It is a story about how little of the universe a human mind can actually understand.

The idea behind it

Solaris is the planet, and the ocean on it is alive. It is not merely alive but active, producing structures and phenomena that decades of scientific study have catalogued without ever explaining. There is an entire field of study devoted to it. There are libraries of observations, taxonomies, and competing theories. None of it has produced a single sentence that anyone is confident means anything.

That is the book’s central argument, and it is delivered calmly and devastatingly: contact may be impossible not because the other party is hostile or distant, but because its mind is shaped so differently that our categories do not apply. Lem is not writing about a monster. He is writing about what it feels like for science to keep taking measurements and keep failing to understand.

Against that, the novel places an intensely private story. The psychologist Kelvin arrives to take up a post on the station and finds that the ocean has begun to send things back to the people observing it: figures drawn from their own memories, solid and unkillable, and impossible to either accept or explain. The cosmic question and the intimate one turn out to be the same question, asked at two different scales.

The story, spoiler-light

Kelvin arrives expecting a functioning research station. What he finds is a place that has gone wrong in ways nobody wants to describe, and a crew that has stopped trusting each other. The book withholds a lot in its opening sections, and the withholding is effective: you learn the situation roughly as Kelvin does, in fragments, with the sense that the people around him are managing you.

Once the central situation is clear, the novel settles into a much quieter and harder story. Kelvin is confronted with something the ocean has produced for him, something he cannot dismiss, cannot reason with, and cannot resolve. What follows is less an investigation than a confrontation with guilt and with the limits of what a person can do about the past. It is a strange, sad book, and much of it takes place in a small number of rooms.

Readers who arrive expecting an expedition or an adventure will find very little of either. Most of the tension is internal, and the station is a setting for an argument about human beings rather than a stage for action.

What makes it science fiction

Lem was a trained scientist and it shows in the texture of the research, but Solaris is not hard science fiction in the sense of rigorous engineering. It is philosophical science fiction: the science is presented seriously, as a human institution with fashions, dead ends and enormous effort, and then shown to be insufficient.

The Symposium, the body of accumulated Solaris research that the book describes, is one of the great satirical inventions in the genre. It is a monument to decades of work that produced no understanding at all, and it is both funny and bleak. If you want to know what the book is doing, read that section closely.

Its influence is hard to overstate. Almost every serious story about an incomprehensible alien intelligence since has been in conversation with Solaris, whether it knows it or not.

Who should read it, and who should give it a miss

• Read it if you want philosophical science fiction that takes its questions seriously.
• Read it if you are interested in first contact stories where the contact simply does not work.
• Read it if you like quiet, unsettling novels more than fast ones.
• Give it a miss if you want answers. The book is built on the absence of them, and it does not resolve that absence.
• Give it a miss if you want action. Almost nothing explodes, and most of the book happens indoors.

Where to start, and what to read next

Solaris is a standalone. One practical note on editions: the novel has a complicated translation history into English, and the most recent edition was translated directly from the Polish, which matters for a book this precise about tone. If you are buying it, that is worth preferring.

It has been filmed twice, by Andrei Tarkovsky in 1972 and by Steven Soderbergh in 2002. Both take the book’s ideas and reshape them considerably, and neither is a substitute for reading it. If you have seen a film and think you know the story, you probably know a different story.

If you want more Lem, his other work ranges from satirical to bleak to comic, and it is worth exploring beyond this one. For more first-contact novels where understanding fails, the genre has a small, excellent tradition that this book effectively started.

The verdict

Solaris is one of the essential science fiction novels, and it earns the position by being genuinely uncomfortable rather than merely clever. It refuses the comfort that most alien-contact stories offer, which is that contact is possible if we are brave or smart enough. Lem’s answer is that it may not be possible at all, and he makes that answer feel like a loss rather than a puzzle.

Read it for the questions. Do not read it expecting a resolution, and do not be surprised when it stays with you for a while afterwards.

Frequently asked questions

Is Solaris hard to read?

It is demanding rather than difficult. The prose is clear, but the book is philosophical and slow, and it does not offer much in the way of plot momentum.

Should I watch a film version instead?

No. Both films take substantial liberties with the book, and the central argument about the limits of understanding is largely in the prose.

Is it part of a series?

No. It is a standalone novel, translated into more than forty languages.
