In "The Crack in Space" by Philip K. Dick, the characters George and Walt represent a unique case of conjoined twins, sharing a single head while possessing distinct personalities. This unusual condition showcases how each twin's consciousness operates independently within their shared physical structure. While George is linked to one hemisphere of the brain, capable of utilizing one eye, Walt operates from the other hemisphere with a separate perspective on life.

The duality of their existence illustrates the complexities of identity and individuality. Each personality exhibits its own traits and viewpoints, leading to a rich exploration of their interactions and experiences in the world. This narrative not only delves into their physical realities but also reflects on the broader implications of consciousness and the nature of self within shared existence.
