Analysis of Arthur C. Clarke’s Childhood’s End

Set in the not-too-distant future, Childhood’s End forecasts a future for the human race that will simultaneously be a transcendence and a termination, as the last generation of children fulfill the destiny of the species.

Reflecting the tensions of the Cold War, the novel opens at a test site for nuclear weapons. But as the crucial moment approaches, suddenly the sky is filled by what can only be an alien spacecraft. Within minutes, news flashes around the world announce that similar craft have appeared over Russian test sites and over every major city on every continent. The technology that put these craft in place is obviously vastly superior to anything the human race has achieved, and the whole world comes to a halt, waiting to see what will happen.

The announcement comes quickly. The visitors have no hostile intention toward the Earth and its inhabitants, but they cannot tolerate the continued testing of weapons that could be so destructive to the human race. The visitors intend to impose peace so that human beings can follow a previously unsuspected path of evolutionary development. Human culture can do whatever it wants to as long as it does not destroy itself. Beyond this, the visitors will not reveal what direction or purpose the human species will develop toward, but they do say that they themselves are in the service of a still more superior life form. These tidbits of knowledge leave more questions than answers, especially since the visitors will not reveal themselves.

Eventually, as human hostilities settle down and as the weapons of mass destruction are made inoperative, all but one ship dissolves from the Earth’s skies. They had all been mere illusions projected from the one ship still hovering over the United Nations. Gradually, some limited contact with the visitors—the Overlords—is allowed, and the Secretary-General of the UN travels regularly to the ship to converse with his contact there.

But he never sees this other presence: the meeting room is set up with a glass between them, brightly lit on the visitor’s side and darkened on the host’s side to create a mirrored surface. Every word and tone exchanged between the Secretary-General and the host Overlord is scrutinized all over the Earth as humans try to reassure themselves that this new force among them is beneficial. Finally, the Overlords announce that they will reveal themselves and interact with human beings in fifty years. On that day, a craft lands, a door opens, and a voice invites a child to come in; then, with the child in his arms, a creature steps out who is indistinguishable from the ancient tales of demons, from the horns on his head to the long tail trailing behind. Even with fifty years to brace themselves, human beings are hardly ready for this.

The Overlords reveal little more about the fate of the human species, saying only that they have come to prepare the way for the one they serve. Just as they are Overlords on the Earth, this superior life form is a kind of Oversoul to the universe, and somehow it will play a part in the fate of the Earth. After the initial shock over their appearance subsides, the Overlords interact freely with humans as observers, attending social events and studying human culture. They seem to have a keen interest in cataloging alleged instances of paranormal activity as they continue to monitor their charges.

Human society has reached new heights of achievement since the devastation and expense of war have been eliminated; nation-states are no longer important, and people experiment with new kinds of communities and new forms of social organization. And it is in just such an experimental artist colony located on an idyllic tropical island that the first signs emerge of where the next phase of human existence is headed. A child there terrifies her mother one day by amusing herself with a rattle that she is not touching. Somehow, the infant is controlling the toy with her mind, having bypassed the usual human dependence on the body.

Soon more and more reports of these extraordinary mental abilities flood in, and soon it is apparent that nearly all children under a certain age have these mental powers. But more important, these children lack something crucially human, since they have no use for or interest in their parents and siblings. Completely absorbed in the discovery and exercise of their mental powers, they are indifferent to family life. In some way, they are distinctly not human, even though they occupy, for the present at least, human bodies.

The parents of such children are distraught, but there is nothing that can return these children to their ordinary state. Beyond their kinetic control of matter, it also becomes apparent that these new human consciousnesses are aware of one another even at remote distances and are gradually uniting themselves into stronger units, collaborating on greater control of the material world. This is the transformation the Overlords had been sent to foster and protect, and eventually they draw these children together on the continent of Australia, emptied for their use, where the children grow mentally stronger and more united.

The tragedy for those who are not part of this transformation—the parents and older siblings—soon becomes apparent, since no old-fashioned babies are being born. The generation of teens and adults that brought forth this new life form will be the last generation on Earth. The response to this terminal condition of the species runs from despair to wild abandon; some can find no reason to live, while others fling themselves into ever more dangerous recreations and sports.

One daring person even stows away aboard an Overlord ship returning to its home world, only to discover that there is no future for humans among these creatures, either. The intelligent universe is composed of the Oversoul; the Overlords, of various species, who serve it but will never be part of it; and the developing species who eventually produce the newest additions to the Oversoul and die out. Like salmon that spawn and die, the human race will have completed its mission and exhausted its purpose once the children are taken into the Oversoul.

As a final act that demonstrates their readiness, the children destroy first the continent they are on and then the Earth itself as they leave it. The Overlords have seen it all many times before and are condemned to continue seeing this spectacle eternally. The stowaway returns on the ship that will carry away the last Overlord supervisor, just in time to witness the end of the world, and, having no other place to go, he stays to be destroyed with it, the last human being in the universe.

Childhood’s End is probably Arthur C. Clarke’s greatest novel. Although it is less well known than 2001: A Space Odyssey, having never been made into a movie and a pop-culture phenomenon, it shares with that story Clarke’s interest in where the human species may be going in the long run. Like the mentally powerful children of Childhood’s End, the cosmic infant created when Dave Bowman is incubated in a cooling star is both a transcendence of human existence and the purpose toward which human effort has been moving all along without anyone’s awareness of it. These novels constitute two of the most original examples of 20th-century science fiction written by an English-born author.
