The Far Side of Evil

by Sylvia Engdahl

A YA novel for high school age and adult readers

On completion of her training as an agent of the interstellar federation's Anthropological Service, Elana is sent to a world whose people may soon destroy their civilization. Since not enough is understood about the situation to justify any interference with their evolution, the Service has no power to act; its agents must go as helpless observers, posing as natives, in the hope of gaining knowledge that may help to save other worlds. This passive role proves intolerable to the young, inexperienced agent assigned to the same city as Elana, a city under totalitarian rule. After falling in love with a local girl who has become Elana's closest friend, he identifies too completely with the natives and unwittingly endangers the entire world by a well-meant but ill-advised attempt to intervene. Forced to assume responsibility for undoing the damage, Elana finds that only she--at great cost--can prevent an immediate war of annihilation.


"Gripping psychological science fiction." London Times Literary Supplement "A surprising, haunting, poetic book." Commonweal "Forceful style ... sparks the reader's imagination." Publisher's Weekly


Please note that although this book has the same heroine as Enchantress from the Stars, it is not a "sequel" but a completely independent and very different story intended for older readers.

Frequently Asked Questions

Firebird edition of The Far Side of Evil

Firebird edition (2005)
Why did you make the second book ahout Elana so different from the first?

I'd had the story in mind for many years, so I started writing it as soon as I finished Enchantress, and since it required interstellar explorers with the same policy as the Service, it couldn't be about a separate organization. I have since been sorry that I used the same heroine; another agent of the Service could just as easily have been the protagonist. None of the other characters from Enchantress appear in it.

What age range did you have in mind when you wrote The Far Side of Evil?

I intended it for high school age. In the era in which it was first published there was no such thing as a Young Adult category; everything not published as adult fiction was issued as a "children's book." Unfortunately, to my great dismay the publisher labeled it "age 10-14" on the jacket because that was the age range that sold best, and because Enchantress from the Stars, which was popular, was suitable for that age (though it too was originally meant for teenagers). I have always regretted connecting The Far Side of Evil so specifically to Enchantress. But when I wrote it, Enchantress hadn't yet been published and I didn't foresee that my books would be given to preadolescent children.

Why do you make such a point of saying that The Far Side of Evil is not suitable for as young an audience as Enchantress from the Stars? Some children have liked it at 10 or 11.

Some children even like adult science fiction at 10 or 11. Young readers unusually mature for their age are not turned away by statements that they are too young for a book. However, Enchantress is often given to average 5th and 6th graders, who enjoy the story even when they don't understand as much of it as older readers do. These children (and teachers who haven't read Far Side) are apt to assume that the second novel about Elana will have similar appeal, when it is actually a very different, and much darker, story that only very exceptional readers below high school age find enjoyable. Children may find its subject matter--torture, imminent nuclear war--disturbing, or they may feel the discussions it contains are too complex to be interesting. No author wants a book to be called "not as good as the first one" simply because it was given to readers not apt to like it as well as its predecessor.

2018 edition of The Far Side of Evil

2018 edition
Especially when other readers may think it's better! Many older teens and adults, especially those not attracted to fantasy, prefer The Far Side of Evil to Enchantress. So the other reason I keep saying it's for older readers is that teenagers often avoid books that are thought suitable for younger kids. Not nearly as many teens have read it as might have done so if it hadn't been called a sequel.

Why didn't you let the characters in The Far Side of Evil find the key to the Critical Stage, the factor that causes some civilizations to destroy their worlds instead of expanding into space?

I've been asked this since friends first read the book before it was published, and my answer has always been the same: If I knew the key, I'd tell the President of the United States instead of putting it in a novel! (Recently, however, I've has some new ideas about the key, which are discussed in my essay Update on the Critical Stage.)

Does that mean you think the Critical Stage is real?

Why does anyone doubt it? I first developed the theory of the Critical Stage in 1956, before the people of planet Earth had any space programs. Then, as throughout most of the years since, the threat of nuclear war was of great concern. It seemed to me that if we didn't turn our attention to space soon, we would very likely destroy ourselves. One of the most encouraging events I've ever witnessed took place just a year later, when Sputnik was launched into orbit, making it impossible for the setting of my story to be Earth. This does not mean, however, that the planet in the story is simply our world under another name, because I believe what I wrote, that the Critical Stage is a natural one that all inhabited worlds go through.

The Far Side of Evil was first published in 1971, during the era of the Apollo moon landings. At that time, I believed Earth was safely out of the Critical Stage. It didn't occur to me that a planetary civilization might cut back its thrust into space once it had gotten started. But that, unfortunately, has been the case with ours. The delays and cutbacks in Earth's space programs have been very alarming to me. (For more of what I think about the Critical Stage, see Space and Human Survival and other essays at this website--including the more recent Thoughts on the 50th Anniversary of the First Moon Landing, in which I express a more optimistic view of the hiatus in space travel.)

Walker edition of The Far Side of Evil

Walker edition (2003)
In the early 70s, when many people wore Peace Symbols as pendants, I went around wearing a Moon Landing medallion (one of many in a collection I then had) because I truly believed that putting humanity's energy into exploration and settlement of new worlds in space was the only way to bring about lasting world peace. I still believe this! I still believe that "We came in peace for all mankind" meant more than just having peaceful intentions toward our competitors in the Space Race of the 60s. Although our world today is no longer so much like the world in the story, there is peril as long as many nations, and many kinds of troublemakers, are competing for the resources of one small planet.

Yet we still have wars even though we have space travel; doesn't that invalidate the premise of the story?

No, because our civilization hasn't made a lasting commitment to a major space effort. We are not established in space in any significant sense--we have simply made some brief trips there and performed some scientific investigation, and then failed to pursue more than a fraction of the space undertakings of which our technology is capable. We've abandoned the moon. We've built no orbiting colonies or even large-scale industrial facilities in space. We've turned our backs on human exploration of Mars. As a species, despite the dedication and enthusiasm of an all-too-small minority of individuals, we are no more committed to expansion into space than we were before we had launched a single spaceship. And so there's as yet no evidence one way or the other as to whether the story's premise is true or not. Space medallion

Isn't the novel more about Earth's political conflicts than about space?

Absolutely not. Some readers thought I used space fiction as a vehicle for political commentary, whereas in fact I used political melodrama to dramatize ideas about the importance of space. Beyond the obvious and uncontroversial premise that dictatorship is a bad thing and totalitarian rulers are motivated by desire for power, the story's main reference to Earth's affairs concerned the youth activism of the late 60s--some of which struck me as comparable to Randil's well-meant but disastrous attempt to change the world overnight. This, however, was a side issue compared to my conviction that expansion into space is the only way of eliminating war on Earth.

Atheneum edition (1971)
Then are you sorry you portrayed a political situation that makes some people consider the book outdated?

That's not what dated the original edition. The planet in the story is comparable to Earth of the 50s, not the 70s; at the time of its publication it wasn't meant to be a portrayal of current conflicts. But the Critical Stage has turned out to last longer than the book suggested; my assumption that the invention of space technology will cause a civilization to immediately put its energy into a space effort has indeed turned out to be invalid.

Furthermore, the Critical Stage has proved to be much more complex than I imagined when I assumed it was merely a brief stage in our planet's history. We now see that nuclear war is not the only danger; we face other threats such as terrorism, biological weapons, destruction of the environment, and depletion of our natural resources--to name only a few of the problems that will eventually confront any civilization confined to a single world. Some people think these disasters can be avoided by effort on our part. I do not. I believe they are the natural consequences of our species being ready to expand into a new and larger ecological niche. In my opinion, the only way we can save Earth is to take up that challenge.

Isn't this too unconventional an opinion to be taken seriously?

Though I can't deny that it's a minority opinion, I am far from alone in holding it. On my Space Quotes to Ponder page I have posted quotations from dozens of people, including some very well-known people, who believe expansion into space is essential to the survival and/or future welfare of our species. Furthermore, in 2017 I added several quotations that specifically state the importance of space to elimnation of war as epigraphs to the ebook and current paperback editions of The Far Side of Evil

Why do you now tell people not to read the original edition of The Far Side of Evil?

Because the 2003 and later editions contain revisions to the story's statements about the Critical Stage that have a major impact on their timeliness. If you haven't already read the old edition, I urge you not to read an old copy, because recent history has invalidated some of the wording I used in 1971. I don't want the book to be less convincing than it would be if read in its updated form, which makes plain that it's the ongoing colonization of space, not merely the invention of space travel, that's crucial to survival.

Collier edition of The Far Side of Evil

Collier editiion (1989)
But in Enchantress from the Stars, colonization is shown as wrong.

Only because the Empire in that story colonized inhabited planets, which as I've said in the FAQ for Enchantress, I don't believe would really happen. Once, the idea that spacefarers might colonize inhabited planets was plausible because of past history, but we have progressed; even today, no one in charge of space policy would consider doing such a thing, so more advanced civilizations surely wouldn't. That's one of the reasons I regret having connected the two books--Enchantress is based on both traditional and recent mythology, whereas The Far Side of Evil is meant to be taken more literally. (When Elana discusses colonization in the revised edition, I wish she could say that civilizations advanced enough to build starships never colonize inhabited planets; but she can't because of her involvement in a story where it happened.)

Incidentally, I disagree strongly with the view held by some people that the term "colonization" should not be used in connection with space because of its negative political connotations. This objection strikes me as invalid and in fact ironic. On Earth colonization involved taking over the land and/or culture of indigenous inhabitants--but that is precisely what a space colony would not do! Nobody, to the best of my knowledge, advocates colonizing inhabited planets, even if we should ever find any. The idea of expanding into space is to abandon our dependence on zero-sum games and thus avoid any more takeovers. A more accurate precedent for the term "colonize" in the space context is its meaning in biology: the establishment of a species' presence in a new ecological niche.

Did you change anything in the 2003 edition besides the discussion of the Critical Stage?

The action of the story hasn't been changed in any way. I removed non-inclusive (sexist) language, and made many other improvements to wording--some I'd long wanted to make and others suggested by my new editor. It is now a better book as well as a more timely one for today's readers.

For more information about the updating, read the Afterword to the 2003 Edition

Why isn't the 2003 edition labeled "revised" on the book itself or in catalogs?

The Library of Congress doesn't consider an edition "revised" unless 20% of it has been altered. I didn't change that much! In my opinion, the wording changes, though minor in terms of length, were of major enough significance to announce, so that people who read the old edition or were considering buying used copies, would realize that the newer one was worth getting. (By now, of course, this isn't a problem since few copies of the 1971 edition still exist.) But Walker chose not to say anything about updating in their publicity, so it's mentioned only in the new Afterword and on the jacket flap.

> British edition of The Far Side of Evil

British editiion (1975)
The cover shown here and by bookellers was new in 2018. Does that mean the book was revised again?

No. The text of the current edition is the same as the 2003 and 2005 editions and the 2011 ebook (except for a few very minor changes to mentions of the Service that I made for consistency with my more recent Captain of Estel trilogy). This is the first time I personally, as distinguished from a publisher's artist, have ventured to portray Elana. In the two books about her I carefully avoided saying what she looked like, since the question of whether she's descended from people of Earth is meant to be an open one. But most of the other editions' covers have shown her in one way or another, so I decided to offer my own visualization, and I have chosen a cover picture that suggests she is of mixed Terrestrial race. (For more about this, see the FAQ for Enchantress from the Stars.) Of course, in this book she is older and in a darker situation than than in Enchantress from the Stars, so she looks different from what readers of that book may have imagined.

What do you think the changes in our world since September 11, 2001, mean in terms of our own Critical Stage?

Several people wrote to ask me this. I'm sorry to say I think the growing problem of international terrorism is exactly what can be expected in a Critical Stage civilization: one that has outgrown its home world but has not yet directed its energies into moving beyond, and in which the evil actions of a few individuals can affect the entire planet. Yet in one way this is a hopeful view; it reflects my belief that the threats we face are not signs of something having gone wrong with our species' evolution, but natural ones against which we must develop defenses, as we must against other natural disasters. I believe we will win the war against organized terrorist networks, just as we got through the crises of the second half of the 20th century--all of which I remember personally. I don't think the world is in any greater immediate danger than it has been since the 1950s, although the American public now has a new awareness of peril. But time is running out (again, see my Space and Human Survival page). To let the current situation distract us from developing space technology would, in my opinion, be self-defeating.

Added November 2, 2006: Recently, my view of this issue has changed somewhat. I now feel that the world will soon be in greater danger from terrorists than in the past because they will have access to emerging new technologies such as biotechnology and nanotechnology, with which they could do great harm. These technologies offer many benefits to humankind and I am certainly not opposed to them, but they could be used destructively by small numbers of people. Therefore, it's important that defenses against them be developed before they are made available, and it's more imperative than ever that a space colony be established as insurance against disaster.
