Arguably, the only science fiction literature that can be considered universal is written by this man!
Clarke is amazing in this story, just as he was in the Space Odyssey Series. Here, man's violent instincts are kept in check by an alien race that humans christened as Overlords. These creatures, who do not show themselves at first, are immensely ahead of human beings in their scientific knowledge and technology. They are peaceful and do not allow violence in any way. Human beings are completely free to do anything they wish, as long as it does not involve violence. There is intrigue, mystery, adventure, drama, and, in the middle of it all, Clarke manages to include several universal themes that are almost imperceptibly philosophical in nature dealing with ethics, religion, politics, etc.
Originally, this was a short story, which was later expanded into a novel and published in 1953. As in the Space Odyssey Series, Clarke describes this new world, new society, the visitors, and, later, their world in such minute details that one, at times, feels they actually exist. Almost like we are reading a non-fiction psychological analysis of this new society and world run by the Overlords. In the process (remember it was written in 1953), he predicts the formation of the European Union, and such technology as photo-realistic computer animation, audience interactivity with entertainment venues, and, most interestingly, the hundreds of TV and radio channels pouring thousands of hours of entertainment, which will (or is?) make(ing) people turn into "passive sponges, absorbing but never creating."
A great story, by a brilliant and prescient man, whose stories are so scientifically possible and accurate that, to this day, they still inspire technological advances (see NASA to launch enormous, Arthur C Clarke-inspired solar sail in 2014 [http://www.wired.co.uk/news/archive/2013-03/26/solar-sail-sunjammer]). Technology and science are not the only subjects of his scrutiny, though. God and faith are frequently discussed in one form or another within his stories. In Childhood's End, I found it curious and somewhat stirring that, in more than one occasion, the Overlords, who were so much more advanced in mastering the physical universe with their science and technology, mention that they could not evolve any further because they didn't have what human beings had: the ineffable entity that is faith and God.
I strongly recommend this book, and the Space Odyssey Series. And you can be sure other novels by Arthur C. Clarke will be inserted into my constantly revised list of "Books I Need to Read."
