In the book "Matilda" by Roald Dahl, a significant theme revolves around the concept of responding to adversity. The quote from Napoleon emphasizes the idea that the best response to being attacked is to take decisive action and retaliate rather than remain passive. This perspective encourages individuals to stand up against their oppressors, drawing strength from within to confront challenges head-on.

This approach is reflected in Matilda's character, who, despite facing neglect and cruelty, uses her intelligence and resourcefulness to counter the difficulties in her life. The narrative promotes resilience and the importance of responding to negativity with determination, making it a powerful message for overcoming life's obstacles.
