The quote "The world changes. Ideologues and zealots don't" from Michael Crichton's "State of Fear" highlights the contrast between the evolving nature of the world and the static beliefs of ideological extremists. It underscores the idea that while society progresses and adapts, certain individuals or groups remain rigid in their views, clinging to outdated ideologies despite new evidence or changing circumstances.

This sentiment reflects a broader commentary on the impact of unwavering beliefs on policy and perception, suggesting that those who are entrenched in ideology may hinder meaningful dialogue and adaptation. In an ever-changing landscape, openness to new ideas and perspectives is essential for progress, while ideologues risk becoming obsolete as the world continues to evolve.
