In "The Lost World," Michael Crichton explores the concept that obsession can be viewed as a form of addiction. This perspective suggests that when individuals become fixated on certain ideas or pursuits, their behavior may mirror the compulsiveness typically associated with substance abuse. Both addiction and obsession can lead to irrational actions and an inability to disengage from the source of fixation, often resulting in negative consequences for the person’s life and relationships.

Crichton's statement underscores the fine line between passion and obsession, emphasizing how intense focus on a single interest can overshadow other important aspects of life. By drawing parallels between addiction and obsession, the book prompts readers to consider the impacts of their own desires and motivations, suggesting a need for balance and moderation to avoid the pitfalls of becoming overwhelmed by one's passions.
