In Shakespeare's "Macbeth," the idea presented is that despite the presence of evil and the fall of those who were once virtuous, there remains a glimmer of goodness in the world. The quote emphasizes that grace and righteousness can persist, even when overshadowed by darkness. It suggests that true virtue is not diminished by the existence of corruption. Additionally, the phrase underscores the theme of appearance versus reality. Even when deceit and foulness may masquerade as grace, true grace must endure and remain distinct. This reflects the play's exploration of morality, ambition, and the struggle between good and evil, illustrating that despite the challenges posed by malevolent forces, the essence of goodness continues to shine through.
