In the book "Founding Brothers: The Revolutionary Generation" by Joseph J. Ellis, the character of Warner Mifflin is introduced as a controversial figure driven by a strong antislavery vision. His motivations are particularly intriguing because he claims that this vision struck him after a remarkable experience of being hit by lightning during a storm, which adds an element of unpredictability to his character.

Mifflin's acknowledgment of the life-altering moment provides insight into how extraordinary experiences can lead individuals to adopt passionate beliefs. His unique background as an "infamous do-gooder of uncertain sanity" raises questions about the nature of conviction and the influences that shape one’s commitment to social causes, particularly in the context of the abolitionist movement.
