Tomorrow, and tomorrow, and tomorrow /
Creeps in this petty pace from day to day [...] /
Life [...] is but a tale /
Told by an idiot, full of sound and fury, /
"Tomorrow, and tomorrow, and tomorrow / Creeps in this petty pace from day to day"
This opening line reflects Macbeth's despair and sense of the futility of time. He sees life as a monotonous progression, with each day passing slowly and indistinguishably from the next. The repetition of "tomorrow" emphasizes the endless, repetitive nature of time, which he perceives as crawling at a petty, insignificant pace.
"Life [...] is but a tale / Told by an idiot"
Here, Macbeth compares life to a meaningless story, narrated by a fool. This suggests his nihilistic view of existence, seeing life as devoid of purpose or significance. The metaphor of life as a tale emphasizes its transient and ultimately inconsequential nature.
"Full of sound and fury, / Signifying nothing"
This iconic phrase encapsulates Macbeth's bleak outlook on life. He describes life as filled with noise and chaos, but ultimately devoid of meaning or substance. The "sound and fury" represent the tumult and turmoil of human existence, but in Macbeth's eyes, they are empty and without purpose.
