In "The Time Machine," H.G. Wells presents a compelling view on the relationship between intelligence and the necessity for change. He argues that true intelligence arises only in the context of adaptability to diverse challenges and needs. Without the impetus to evolve or confront varying circumstances, intelligence remains dormant, indicating that the ability to thrive in a shifting environment is what signifies greater mental capability.

This idea highlights that animals, including humans, develop cognitive abilities as a response to the myriad of demands life imposes upon them. Those that face numerous challenges in their ecosystem tend to cultivate intelligence, suggesting that evolution and intelligence are intrinsically linked to survival and adaptation in the face of a dynamic world.
