Read the passage from "Mutability." By contrasting "darkness" with "radiantly," Shelley
We are as clouds that veil the midnight moon;
How restlessly they speed, and gleam, and quiver,
Streaking the darkness radiantly!—yet soon
Night closes round, and they are lost for ever:
o emphasizes that although life is fleeting, it is exciting.
O compares the spark of creativity to the enduring night
sky.
O introduces the idea that people are destined to live life
in darkness.
O explains that people are permanent, bright fixtures
like the heavens.
