In Philip K. Dick's "Time Out of Joint," the character Ragle emphasizes the essential survival principle of adapting to changing circumstances. He suggests that those who are unable or unwilling to respond to new challenges will ultimately face extinction. This underscores the importance of flexibility and adaptability in navigating life's complexities.

This notion serves as a reminder of a fundamental truth: survival often hinges on one's ability to evolve with the environment. The idea of "adapt or perish" reflects a timeless reality, highlighting the necessity of resilience in the face of change, a theme that resonates throughout the narrative.
