" Man’s yesterday may never be like his morrow; Nought may endure but Mutability. "
- Percy Bysshe Shelley

This quote by Percy Bysshe Shelley emphasizes the ever-changing nature of human life and experiences. It suggests that what we experience today will inevitably be different from tomorrow, reflecting the transient qualities inherent in our lives. The idea here is that nothing remains constant or unchanging; everything evolves over time.

The deeper meaning behind this statement touches on several philosophical concepts, including impermanence and the futility of seeking permanence in life's fleeting moments. Shelley asserts that change is an intrinsic part of existence, making it impossible for any aspect of human experience to remain static indefinitely. This insight can be both comforting and disconcerting; it offers solace by acknowledging that all things will pass but also highlights the unpredictability of future events. By embracing mutability, individuals might find a sense of acceptance towards life’s continual transformations.

Percy Bysshe Shelley was an English Romantic poet widely recognized for his influential contributions to literature during the early 19th century. His works often explore themes of freedom, individuality, and social justice through innovative poetic forms and poignant narratives. Shelley's perspective on change and impermanence is reflective not only of personal experiences but also of broader philosophical inquiries into human existence and societal progress.
