Throughout the book, Clarke ties power to knowledge, both in that knowledge itself can be leveraged as power and in that the lack of knowledge can create a lack of power. Late in the novel, George Greggson considers the fact that he accepted—with no proof or even indication—that the Overlords were all-knowing and all-powerful, until he was told about the existence of the Overmind. This acceptance that the Overlords were the most powerful beings in the universe was nearly universal among humans; the Overlords' clear technological advancement was enough to make all of humanity agree to let them rule over Earth with no actual fight. Then, throughout the novel, the Overlords refer to the lack of knowledge humanity has and to humanity's inability to understand the universe around them. This is among the reasons that Earth is powerless; Earth cannot be powerful because Earth does not have enough knowledge.
Clarke plays with the idea of mysticism, or a near-religious belief in the supernatural, and humans' ability to grasp what they witness. The Overlords' presence effectively brings organized religion to an end, and yet religious concepts emerge time and again. The Overlords look like the Christian depictions of devils, and later in the novel George begins to think of them in religious ways when his son Jeffrey hears a voice in his head guiding him to safety. In fact, what humanity believes is paranormal or mystic appears to be the Overmind, which itself is a nonphysical entity that could be called divine in nature, guiding the actions of all other races and species once it absorbs them. The Overlords envy humans' capacity for the mystical irrationality that allows them to be absorbed by the Overmind. Although this seems at odds with the scientific and technological concepts in the novel, the Overmind can also be seen as an exploration of the unknown and the ways in which humankind sorts through the mysteries of the universe.
Clarke poses questions about the nature of dictatorship and freedom throughout the novel. The Overlords are shown to have little direct interaction with humanity, and yet they are the unquestioned rulers. Professor Sullivan, a scientist who helps Jan Rodricks stow away on an Overlord ship, is anxious to defy them, despite the fact that the Overlords have never punished any human in living memory. The Overlords watch all and can see all, but that is not widely known. Instead, humanity has given up its liberty to a race that most people have never seen in person. This is due in part to the illusion of freedom the Overlords create. By easing all the problems on Earth and giving humanity everything material that it needs, the Overlords create a sense of freedom without actually granting freedom to anyone. People can travel, work as they like, and do almost anything—as long as it does not alter the plan the Overlords have for humankind. Their dictatorship is benevolent and almost invisible, but nonetheless, the Overlords are in charge.
One of the core ideas of the novel is that utopia and creativity are incompatible. The Overlords have created a utopia on Earth, but humanity is unable to create any meaningful art or inventions. With this juxtaposition, Clarke suggests that creativity only thrives on struggle and that there must be problems for innovation to flourish. This idea is not unique to Clarke; throughout history, people have thought that creativity requires hardship. Yet for Clarke, utopia creates complacency, and with complacency comes a lack of initiative to generate new, groundbreaking ideas.
