"Children of the Mind" by Orson Scott Card explores the nature of belief and reality through its fictional narratives. The statement, "All the stories are fictions. What matters is which fiction you believe," highlights the idea that the narratives we embrace shape our understanding of the world. It emphasizes that while stories may be invented, the impact they have on our lives is profoundly significant.

This quote encourages readers to reflect on the power of belief in shaping personal and collective experiences. It suggests that our chosen fictions can influence our decisions, relationships, and perceptions, reinforcing the notion that meaning is derived from the stories we decide to trust and follow. Ultimately, it underscores the importance of critically evaluating the narratives we accept in our lives.
