Out of the Silent Planet is a science fiction novel by the British author C. S. Lewis, first published in 1938 by John Lane, The Bodley Head. Five years later it was published in the U.S. (MacMillan, 1943). Two sequels were published in 1943 and 1945, completing the so-called Cosmic Trilogy or The Space Trilogy. Written as a response to earlier genre fiction, it incorporates themes of moral theology and myth in a way typical of other members of The Inklings group.
While on a walking tour, the philologist Elwin Ransom is drugged and taken on board a spacecraft bound for a planet called Malacandra. His abductors are Devine, a former college acquaintance, and the scientist Weston. Wonder and excitement relieve his anguish at being kidnapped, but he is put on his guard when he overhears his captors discussing their plans to turn him over to the inhabitants of Malacandra as a sacrifice.
Soon after the three land, Ransom escapes and then runs off in terror upon first seeing the vaguely humanoid but alien sorns. In his wanderings, he finds that all the lakes, streams, and rivers are warm, that gravity is significantly lower than on Earth, and that the plants and mountains are all extremely tall and thin. After meeting a hross named Hyoi, a civilised native of a different species, Ransom becomes a guest for several weeks in Hyoi's village, where he uses his philological skills to learn the language. Discovering that gold (known as "sun's blood"), is plentiful on Malacandra, he discerns Devine's motive for making the voyage.
While out hunting, Ransom and his hrossa companions are told by an eldil, an almost invisible, angelic creature, that Ransom must go to meet Oyarsa, who is ruler of the planet, and indeed that he should already have done so. Shortly after, Hyoi is shot dead by Devine and Weston as they track Ransom and Ransom is directed by the hrossa to comply with the eldil's instructions and cross the mountains to the cave of a sorn named Augray.
On the way Ransom discovers that he has almost reached the limit of breathable air and has to be revived by Augray with a flask of oxygen. The next day, carrying Ransom on his shoulder, Augray takes him across the bleak tableland and down into another river valley to Meldilorn, the island home of Oyarsa. There Ransom meets another species, a pfifltrigg who tells him about the beautiful houses and works of art that his people make in their native forests.
Ransom is led to Oyarsa, who explains that there is an Oyarsa for each of the planets in the solar system. However, the Oyarsa of Earth - which is known as Thulcandra, "the silent planet" - has become "bent", or evil, and has been restricted to Earth after "a great war" on the authority of Maleldil, the ruler of the universe. Ransom is ashamed at how little he can tell the Oyarsa of Malacandra about Earth, and how foolish he and other humans seem to Oyarsa.
While the two are talking, Devine and Weston are brought in, guarded by hrossa, because they have killed three members of that species. Weston does not believe that Oyarsa exists and he is incapable of conceiving that the Malacandrians are anything but ignorant natives, exploitable and expendable. This emerges in the course of a long speech in which Weston justifies his proposed invasion of Malacandra on "progressive" and evolutionary grounds. Weston's motives are shown to be more complex than profit: he is bent on expanding humanity through the universe, abandoning each planet and star system as its resources are exhausted and it becomes uninhabitable. In Ransom's attempts at translation, the brutality and crudity of Weston's ambitions are laid bare.
While acknowledging that Weston is acting out of a sense of duty to his species - and does not share Devine's greed for gold - Oyarsa tells Weston and Devine that he cannot tolerate their disruptive presence on Malacandra; they must leave the planet immediately, even though under very unfavourable orbital conditions. Oyarsa offers Ransom the option of staying, but Ransom decides he does not belong there either. The voyage back is barely made with just ninety days' worth of air and other supplies and the spaceship is "unbodied" soon after landing.
In the final chapter, Lewis introduces himself as a character into his own novel. He had written to Ransom enquiring whether he had come across the Latin word Oyarses, discovered in a mediaeval Neoplatonist work. This prompts Ransom to share his secret and the two resolve to hinder Weston from doing further evil in view of "the rapid march of [contemporary] events".
A Postscript quotes one of Ransom's letters to the author expressing frustration at how condensation of his adventures obliterates the rich detail of what he has learned and witnessed.
- Dr Elwin Ransom – A professor of philology at a college of the University of Cambridge.
- Dr Weston – A thick-set physicist, ruthless and arrogant, who mocks "classics and history and such trash" in favour of the hard sciences.
- Dick Devine – Weston's accomplice who "was quite ready to laugh at Weston's solemn scientific idealism. He didn't give a damn, he said, for the future of the species or the meeting of two worlds."
- Hyoi – Ransom's first hross contact.
- Hnohra – An older hross who acts as Ransom's language teacher.
- Augray – A mountain-dwelling sorn.
- Kanakaberaka – A pfifltrigg who carves Ransom's portrait onto a stone at Meldilorn.
- Oyarsa – The spirit ruler of Malacandra whose demand to meet a human before allowing further exploration of his planet precipitates the kidnapping of Ransom.
Hrossa, séroni, and pfifltriggi
On Malacandra there are three native species of reasoning hnau.
The hrossa (singular hross) resemble bipedal otters or seals, and are somewhat taller and thinner than humans. Ransom finds them beautiful: "covered, face and all, with thick black animal hair, and whiskered like a cat ... glossy coat, liquid eye, sweet breath and whitest teeth" (p. 59, Chap. 9). They live in the low river valleys (handramit in the speech of the eldila), which they travel by boat, and specialise in farming, fishing, and such performing arts as dancing and poetry. Their technical level is low, and they wear only pocketed loincloths. Their speech is characterised by adding an initial /h/ sound to the words in the planet's common vocabulary. Their sense of humor is "extravagant and fantastic" (Chap. 18).
The séroni (singular sorn; the plural is sometimes given as sorns) are thin, fifteen-foot-high humanoids having coats of pale feathers and seven-fingered hands.[a] They live in mountain caves of the high country (harandra in the speech of the eldila), though they often descend into the handramit where they raise giraffe-like livestock. They are the scholars and thinkers of Malacandra, specializing in science and abstract learning. Their technical level is high, and they design machinery, which is built by the pfifltriggi. Although they can write, they do not compose written works of history or fiction as they feel the hrossa are superior at it. Their sense of humor "seldom got beyond irony" (Chap. 18).
The pfifltriggi (singular pfifltrigg) have tapir-like heads and frog-like bodies; they lean their elbows on the ground when at rest, and sometimes when working with their hands. Their movements are quick and insectlike. They are the builders and technicians of Malacandra. They build houses and gadgets thought up by the séroni. They are miners who especially like to dig up "sun's blood" (gold) and other useful and beautiful minerals. Their sense of humor is "sharp and excelled in abuse" (Chap. 18).
Members of the three races do not believe any one of the races to be superior to the others; they acknowledge, rather, that no single race can do everything.

Lewis wrote Out of the Silent Planet during 1937 after a conversation with J. R. R. Tolkien in which both men lamented the state of contemporary fiction. They agreed that Lewis would write a space travel story and Tolkien would write a time travel story. In fact, Tolkien never completed his story, while Lewis went on to compose two others over the war years in Britain. These are now referred to as the Cosmic or Space Trilogy, or occasionally as The Ransom trilogy after the main character, Elwin Ransom.
Lewis was an early reader of H.G. Wells and had been given a copy of The First Men in the Moon as a Christmas present in 1908. Ransom makes dismissive references to Wells' conceptions in the course of the novel, but Lewis himself prefaced early editions of the novel with the disclaimer that "Certain slighting references to earlier stories of this type which will be found in the following pages have been put there for purely dramatic purposes. The author would be sorry if any reader supposed he was too stupid to have enjoyed Mr. H. G. Wells' fantasies or too ungrateful to acknowledge his debt to them." Another early work of space fiction which he later acknowledged was David Lindsay's A Voyage to Arcturus (1920).
But there were other speculative works, in answer to which Out of the Silent Planet was written as a decided reaction. In both Olaf Stapledon's Last and First Men (1930) and an essay in J. B. S. Haldane's Possible Worlds (1927), Lewis detected what he termed Evolutionism, an amoral belief that humanity could perfect from itself a master race that would spread through the universe. Such was the ideology that Weston championed in his debate with Oyarsa, only to have it travestied by Ransom's translation of it into Malacandran.
In the end, very few of the novel's original reviewers even realised that Lewis' intent was to substitute theological values through its means for those he deplored on the side of Scientism. Noting this omission, he pointed out to one of his correspondents that "any amount of theology can now be smuggled into people’s minds under cover of romance without their knowing it". In the novel itself, Ransom proposes a similar but subtler approach in his letter to Lewis quoted in the postscript: "What we need for the moment is not so much a body of belief as a body of people familiarized with certain ideas. If we could even effect in one per cent of our readers a change-over from the conception of Space to the conception of Heaven, we should have made a beginning."
What Lewis actually offers as substitute views are a series of reversals. His Malacandra is in fact the planet Mars which, named after the Roman god of war, was once viewed astrologically as the influencer of self-assertion and disruption. However, in place of Wells' scenario in The War of the Worlds, in which the inhabitants of Mars come to Earth as invaders, Lewis portrays a world of different species living in harmony from which members of his own corrupted species are expelled as bringers of violence and exploitation.
Again, the clock is turned back from the world view of the post-mediaeval Renaissance to that of the Renaissance of the 12th century with the novel's vision of the universe as "the field of Heaven" peopled by aetheric angels. It had been the aim of Lewis' scholastic study, The Allegory of Love (1936) to revalidate the standpoint of the mediaeval literature flowing from that time and a reference to one of its key authors is introduced as the reason for Lewis to contact Ransom in the first place. In Lewis' study, the authors of the Platonic School of Chartres are presented as "pioneers of medieval allegorical poetry…For them, Nature was not opposed to Grace but, rather, an instrument of Grace in opposing the Unnatural", which is one of the transformative ideas with which the novel's readers are to be familiarized. A prominent associate of the school was Bernardus Silvestris, whose study of the creation underpins Oyarsa's discussion with Ransom in the novel. Indeed, the school's use of allegory as a vehicle for "psychological realism" may be claimed as the ultimate model for Lewis' own work nine centuries later.
Weston's speech and its translation
The speech which Weston delivers at the book's climax (in Chapter 20), and Ransom's effort to render it into the language of Malacandra, demonstrates the gulf in cultural and moral perceptions between the planetary mind sets and may be said to make a sort of social criticism.
|Weston's speech in English||Ransom's rendering into Malacandran, "which he felt to be rather unsatisfactory"|
|To you I may seem a vulgar robber, but I bear on my shoulders the destiny of the human race. Your tribal life with its stone-age weapons and bee-hive huts, its primitive coracles and elementary social structure, has nothing to compare with our civilization – with our science, medicine and law, our armies, our architecture, our commerce, and our transport system which is rapidly annihilating space and time. Our right to supersede you is the right of the higher over the lower.||Among us, Oyarsa, there is a kind of hnau who will take other hnau’s food – and things, when they are not looking. He says he is not an ordinary one of that kind. He says what he does now will make very different things happen to those of our people who are not yet born. He says that, among you, hnau of one kindred all live together and the hrossa have spears like those we used a very long time ago and your huts are small and round and your boats small and light like our old ones, and you only have one ruler. He says it is different with us. He says we know much. There is a thing happens in our world when the body of a living creature feels pains and becomes weak, and we sometimes know how to stop it. He says we have many bent people and we kill them or shut them in huts and that we have people for settling quarrels between the bent hnau about their huts and mates and things. He says we have many ways for the hnau of one land to kill those of another and some are trained to do it. He says we build very big and strong huts of stones and other things – like the pfifltriggi. And he says we can exchange many things among ourselves and can carry heavy weights very quickly a long way. Because of all this, he says it would not be the act of a bent hnau if our people killed all your people.|
|Life is greater than any system of morality; her claims are absolute. It is not by tribal taboos and copy-book maxims that she has pursued her relentless march from the amoeba to man and from man to civilization.||He says that living creatures are stronger than the question whether an act is bent or good – no, that cannot be right – he says it is better to be alive and bent than to be dead – no – he says, he says – I cannot say what he says, Oyarsa, in your language. But he goes on to say that the only good thing is that there should be very many creatures alive. He says there were many other animals before the first men and the later ones were better than the earlier ones; but he says the animals were not born because of what is said to the young about bent and good action by their elders. And he says these animals did not feel any pity.|
|She has ruthlessly broken down all obstacles and liquidated all failures and to-day in her highest form – civilised man – and in me as his representative, she presses forward to that interplanetary leap which will, perhaps, place her for ever beyond the reach of death.||He says that these animals learned to do many difficult things, except those who could not; and those ones died and the other animals did not pity them. And he says the best animal now is the kind of man who makes the big huts and carries the heavy weights and does all the other things I told you about; and he is one of these and he says that if the others all knew what he was doing they would be pleased. He says that if he could kill you all and bring our people to live in Malacandra, then they might be able to go on living here after something had gone wrong with our world. And then if something went wrong with Malacandra they might go and kill all the hnau in another world. And then another – and so they would never die out.|
|It is in her right, the right, or, if you will, the might of Life herself, that I am prepared without flinching to plant the flag of man on the soil of Malacandra: to march on, step by step, superseding, where necessary, the lower forms of life that we find, claiming planet after planet, system after system, till our posterity – whatever strange form and yet unguessed mentality they might have assumed – dwell in the universe wherever the universe is habitable.||He says that because of this it would not be a bent action – or else, he says, it would be a possible action – for him to kill you all and bring us here. He says he would feel no pity. He is saying again that perhaps they would be able to keep moving from one world to another and wherever they came they would kill everyone. I think he is now talking about worlds that go round other suns. He wants the creatures born from us to be in as many places as they can. He says does not know what kind of creatures they will be.|
|I may fall, but while I live I will not, with such a key in my hand, consent to close the gates of the future on my race. What lies in that future, beyond our present ken, passes imagination to conceive: it is enough for me that there is a Beyond.||He is saying that he will not stop trying to do all this unless you kill him. And he says that though he doesn’t know what will happen to the creatures sprung from us, he wants it to happen very much.|
