Here’s why the C. S. Lewis Space Trilogy is an important choice for homeschool high schoolers.

C. S. Lewis Space Trilogy
Teens need to:
- Learn to recognize God’s leading and bravely follow
- Learn to recognize and stand up to modernistic philosophies that are destructive
- Learn to stand up to people who are destructive
- Learn to think imaginatively in understanding problems and creating solutions
While C. S. Lewis did not write the Space Trilogy specifically for teens, he did cover all these bases.
The Space Trilogy tells the story of Elwin Ransom, a respected Cambridge University professor of philology (the study of languages), who goes for a walk one day and ends up on Mars. He’s on Mars not by his own will but because he was kidnapped and smuggled there!
Ransom’s adventures on Mars are the topic of the first book of the Space Trilogy, titled Out of the Silent Planet. Written in 1937, long before Hubble telescopes or space travel, C.S. Lewis was free to create a fantasy world on Mars. It was full of different kinds of “peoples” (certainly not what humans on Earth would call “people”): hrossa, seroni, and eldila.
Ransom learns to accept and love the “people” of Malacandra (their name for Mars).
He also must defend the Malacandrians from the evil-doers who kidnapped him. These men exemplified the modernistic philosophies that C.S. Lewis believed were destructive (materialism- the love of “stuff”, humanism- the adulation of mankind, scientism- the worship of science)- and besides that, they were just plain bad guys who did bad things.
Ransom comes to know the angels (eldila) appointed by God to help in that world and through that connection he begins to understand the reality of the spirit realm.
C. S. Lewis had four goals for Out of the Silent Planet:
- He wanted to smuggle Christian theology into a good story
- He wanted to “baptize his readers’ imagination”. In other words, he wanted to write such an out-of-the-box story that it helped the reader’s imagination to grow.
- He wanted to fight modernistic philosophies and worldviews.
- He wanted to show that God’s angelic realm is “more real” than our tangible world.
In the following beautifully written books of the Space Trilogy, Perelandra and That Hideous Strength, Lewis continues to chronicle Ransom’s God-ordained missions. As they read about Ransom’s missions, homeschool high schoolers will learn to recognize “this is God’s leading,” “this is the trick of the evil one,” “this is philosophically dangerous,” or “this action will line up with my philosophy.”
The 7 Sisters Study Guides for Out of the Silent Planet, Perelandra, and That Hideous Strength contain no busywork; instead they give simple information on the theological and philosophical concepts C.S. Lewis has embedded in the stories. The guides coach high schoolers through the concepts with comprehension and inferential questions.
Most appropriate for teens who are at the “Deep Thinking Stage of Life”, the Space Trilogy is a useful Literature choice to add richness to History and Philosophy of the Western World.
Don’t let high school go by without bringing the C.S. Lewis Space Trilogy to your homeschoolers!

I’m teaching these books to a small group of homeschoolers in the next school year. My interest in your study guides is somewhat tempered by the fact that you mentioned eldilla as if they were the third type of Malacandrian (the actual third type was the pftfltriggi, the eldila are found in places other than Malacandria). It makes me wonder just how deeply you’ve actually read the books, and whether I’d be better off crafting my own questions based on lit crit in books like: Planets In Peril, Deeper Heaven, and Narnia and The Fields of Arbol. I was looking for truly thoughtful questions, and real insight into what Lewis is doing in the books. While he was certainly working to get Christian ideas past sleeping lions, and he certainly took the philosophical ideas expressed in The Abolition of Man and The Discarded Image and wove them into a fictional narrative, these books are much richer than just a tract. I’m really wondering the extent to which your study guides go into the extensive reading that Lewis himself did which is reflected in the Ransom trilogy. For example, do you make it clear that Bernardus Silvestris was a real author whose ideas actually do partly inform Lewis’s thought? Do you discuss how Lewis took the idea of a science fiction type book with a religious philosophical message from an author whose philosophy he vehemently disagreed with? Do you go into the nature of the eldila? Do you discuss the issues of cosmology? Those are the kinds of subjects that I’m hoping to find study guides addressing. Do you pose thoughtful questions about the role of memory in pleasure? Do you even address the ways in which Lewis draws on earlier authors like Swift (whom my students and I read some of last year), Milton, and Dante? Do you look specifically at Lewis’s careful choice of words? These are books of such richness that scholars are mining new things from them all the time. I would hate to have them simply turned into books that kids viewed as the same kind of twaddle they would find in some moralistic story they would find in certain homeschool curricular anthologies. I have a deep love for Lewis’s work, and his works along with those of Tolkien, and to a lesser degree Stephen Lawhead helped to shape my own children’s world view. I would hate to use study questions that really interfere with the students’ just plain enjoyment of the books. I believe in the use of background material (and Lewis took the medieval view that borrowing from other authors was perfectly acceptable) and I would expect a study guide author to be aware of some of the reading Lewis did which informed these books. In addition, while I certainly hope that my students will draw moral, theological, and other lessons from the books I would hate to use study questions that simply force a particular conclusion. I think perhaps in my career as a 20+ year homeschooling mom, and a literature teacher of homeschooled students for nearly another two decades, I have more than once too often come across study guides that diminished rather than enhanced the experience of the reader. I an now really cautious about buying a “pig in a poke.” I am asking these questions because there is no possibility of viewing a sample of your study guide on Kindle, nor do you offer any sample selections here. I’m really looking for a thoughtful study guide written by someone who really knows their way around Lewis’s work, not simply a study guide with “reading comprehension” type questions written by someone who has merely read through the books once themself. I certainly can write my own study questions, I was simply hoping that there was a guide out there which had those kinds of thoughtful questions, and the title of this link made me think perhaps this was it.
