Meaning: The quote "Man's yesterday may never be like his morrow; Nought may endure but Mutability" is a thought-provoking reflection on the transient and ever-changing nature of human existence. It was penned by the renowned English Romantic poet Percy Bysshe Shelley, who is celebrated for his lyrical and introspective poetry that often delves into themes of nature, mortality, and the human experience.

In this particular quote, Shelley contemplates the fleeting nature of time and the inevitability of change. The phrase "Man's yesterday may never be like his morrow" suggests that the past is always distinct from the future, and that what has transpired before may never be replicated or relived in the same way. This notion underscores the idea that each moment in time is unique and cannot be fully recaptured or repeated.

The second part of the quote, "Nought may endure but Mutability," further emphasizes the idea of impermanence. The word "Mutability" refers to the quality of being liable to change, and Shelley's assertion that "Nought may endure" underscores the notion that nothing is permanent or everlasting. This concept aligns with the broader Romantic emphasis on the transitory nature of life and the impermanence of human existence.

Shelley's contemplation of mutability and the transient nature of human experience is deeply rooted in the Romantic movement's fascination with the natural world and the human condition. Romantics often sought to explore the profound emotional and spiritual dimensions of existence, and Shelley's quote reflects this preoccupation with the ephemeral and ever-changing aspects of life.

Throughout his body of work, Shelley grappled with themes of transience, mortality, and the passage of time. His poetry frequently evokes a sense of wonder and awe at the natural world, as well as a poignant awareness of the fleeting nature of human life. In "Ode to the West Wind," for example, Shelley personifies the wind as a powerful force of change, reflecting his enduring fascination with the transformative and mutable aspects of existence.

Shelley's quote also resonates with broader philosophical and literary traditions that have contemplated the nature of time and change. The ancient Greek philosopher Heraclitus, for instance, famously espoused the notion that "change is the only constant" and that everything is in a state of flux. Similarly, in the realm of literature, writers and poets have long grappled with the theme of mutability, exploring the ways in which the passage of time shapes human experience and perception.

In conclusion, Percy Bysshe Shelley's quote "Man's yesterday may never be like his morrow; Nought may endure but Mutability" encapsulates a profound meditation on the transient and ever-changing nature of human existence. Through his evocative language and keen insight, Shelley invites readers to contemplate the impermanence of time and the inevitability of change, echoing enduring themes that have captivated philosophers, writers, and artists across centuries.
