In Childhood's End Arthur Clarke gives the impression that knowledge of technology equals power,not just physical power but psychological power as well. Evolution seems to be a key theme that is constant throughout this story and Time Machines. Although they both differ in the sense of where mankind will eventually end up, they both share some common similarities. In Childhood's End, the Overlords use their technology to achieve a technological overpower on mankind. The Overlords technology apparently has no limits.

In Childhood's End, Karellen speaks of how all of human development leads up to the moment when the children of the last generation join the Overmind. But what are the motives of the Overmind?. In the novel, the purpose of mankind is only to develop to the point at which it can join the conscious of the Overmind.

However, in Childhood's End, most of the characters as well as the Overlords and Jan Rodricks agree that "the stars are not for man."As Karellen says when he announces the transformation of the children, "All the hopes and dreams of your race are ended now." This quote seems to have the most significant truth to what we eventually hope to evolve towards. It almost seems like Karellen is speaking about the individual dreams that each human has. We all live for the
