In Margaret Atwood's novel "The Year of the Flood," the quote "Without the light, no chance; without the dark, no dance" highlights the interdependence of contrasting elements in life. The idea suggests that light represents hope, opportunity, and positivity, while darkness symbolizes challenges and struggles. Together, they create a balanced existence, where one cannot fully appreciate the other.

This duality emphasizes that both light and dark experiences shape our lives. Without moments of hardship and difficulty, the joys and successes would feel less meaningful. Atwood's exploration of these themes encourages readers to acknowledge that life's complexities enrich our understanding and appreciation of both happiness and sorrow.
