In this quote from Shakespeare's Macbeth, the speaker emphasizes that the depth of one’s grief should not be determined by the value or significance of the person lost. Instead, if sorrow is based on the worth of others, it risks becoming an endless cycle of mourning.
This idea highlights the futility of measuring personal loss against another's importance. It suggests that sorrow is a complex emotion that should be acknowledged for its own sake, detached from the qualities of the individual involved. Ultimately, this reflects the universal struggle with grief and the challenges of letting go.
