In Michael Crichton's "Jurassic Park," the notion that people are not motivated by lofty ideals, such as the pursuit of truth, is emphasized. Instead, individuals are more influenced by their immediate desires, fears, and practical considerations. This perspective suggests that human behavior is often guided by tangible interests rather than abstract principles.

This insight into human motivation resonates throughout the story, as characters act based on personal gain, survival instincts, and emotional responses to the high-stakes environment of the park. It illustrates that when faced with extraordinary circumstances, the complexities of human nature come to the forefront, overshadowing any idealistic pursuits.
