In "Ender's Shadow," Orson Scott Card explores the notion that many aspects of human behavior stem from ancient responses to dangers that no longer exist. The quote emphasizes how our instincts and reactions are often shaped by historical threats, suggesting that we are influenced by a legacy of survival rather than current realities. This perspective encourages readers to reflect on how our past informs our present actions and thought processes.

This idea extends beyond individual behavior, highlighting a collective pattern seen in societies. People may react to modern challenges with outdated strategies rooted in fear or survival mechanisms, indicating a disconnect between our instincts and the contemporary world. Card's work urges an examination of these behavioral patterns to foster better understanding and adaptation in an ever-evolving landscape.
