In Margaret Atwood's "The Handmaid's Tale," the quote reflects the duality of existence, emphasizing that light and shadow are interdependent. The concept of resistance embodies this idea, suggesting that the struggle against oppression is essential for freedom and hope. Just as light defines shadow, the fight for rights and dignity highlights the importance of standing against tyranny.

This perspective illustrates that without the challenges posed by darkness, the value of freedom and resistance would be diminished. Atwood's narrative reinforces this belief, as the characters navigate a world of repression while holding onto their aspirations for a brighter future. The interplay between hope and despair serves as a powerful reminder of the necessity of resilience amidst adversity.
