In Jodi Picoult's "Plain Truth," a conversation reveals a significant clash between differing beliefs. Adam confronts the skeptic with a statement about belief, emphasizing that his understanding goes beyond just the visible world. He suggests that true belief can often stem from faith in the invisible, challenging the other person's perspective.

This exchange underscores the themes of belief and perception in the story. Adam's conviction implies that many truths remain unseen and that acknowledgment of such truths can broaden one's understanding of reality. The dialogue highlights how belief is not solely reliant on tangible evidence but can also be deeply personal and rooted in one’s experiences.
