"Life" is personified as a story being narrated, but instead of a coherent and meaningful tale, it is portrayed as a chaotic, nonsensical jumble of sounds and passionate emotions, with no clear purpose or direction. The phrase implies that life is filled with meaningless noise and tumultuous activity that amounts to nothing in the end.
The use of the word "idiot" suggests a narrator who lacks intelligence or understanding and, thus, cannot provide any profound insight or moral guidance. This portrayal highlights the idea that life is incomprehensible and devoid of any profound meaning or purpose, leaving individuals searching for answers and finding none.
The repetition of "full of sound and fury" emphasizes the intensity and emotional nature of these meaningless events, representing the passionate actions and desires of individuals that ultimately add up to nothing substantial or lasting.
Overall, this statement expresses a deeply pessimistic view of life, capturing the existential angst of individuals who find themselves amidst a relentless stream of events without any clear purpose or meaning.
