In her novel "Wolf Hall," Hilary Mantel explores the psychological effects of uncertainty on individuals and society. The quote highlights that when facts are missing, people tend to fill that void with their own fears and desires, leading to irrational beliefs and anxieties. It suggests that the unknown can be more terrifying than known facts, as it allows for a range of interpretations and emotions to take root.

This idea underscores the importance of knowledge and information in stabilizing people's thoughts and actions. Without reliable data, individuals may become trapped in a cycle of speculation, which can lead to chaos and misunderstanding. Mantel’s work illustrates how the absence of clarity can provoke deep-seated emotional responses and, ultimately, significant consequences in human relationships and historical events.
