What may this mean, / That thou, dead corse, again in complete steel, / Revisit’st thus the glimpses of the moon, / Making night hideous, and we fools of nature / So horridly to shake our disposition / With thoughts beyond the reaches of our souls?
Act I, Scene 4 · Hamlet
Context
Still addressing the Ghost, Hamlet demands to know why it has returned from the grave in armor, describing the unnatural terror it causes in the living observers.
Analysis
The phrase 'glimpses of the moon' reduces the Ghost's visible world to fragmentary, unstable light—it exists only in brief flashes, not in daylight clarity. By calling himself and his companions 'fools of nature,' Hamlet suggests that as mortals they are nature's dupes, unable to comprehend what lies beyond death. The line 'thoughts beyond the reaches of our souls' uses spatial metaphor (reaching, extending) to describe the limits of human understanding, making ignorance feel like a physical boundary the mind cannot cross.
Essay Tip
Support a thesis that the Ghost forces Hamlet into epistemological crisis—this quote shows him confronting the limits of what humans can know, a confrontation that will make decisive action nearly impossible for him later.
