In "A Defence of Poetry,” Shelley suggests that thoughts and feelings in life are "always arising unforeseen and departing unbidden.” Which lines from "Mutability” also reflect the idea that life is fleeting?
-We are as clouds that veil the midnight moon;
How restlessly they speed, and gleam, and quiver
-Or like forgotten lyres, whose dissonant strings
Give various response to each varying blast
-We rest.—A dream has power to poison sleep;
We rise.—One wandering thought pollutes the day
-We feel, conceive or reason, laugh or weep;
Embrace fond woe, or cast our cares away
-We are as clouds that veil the midnight moon;
How restlessly they speed, and gleam, and quiver
-Or like forgotten lyres, whose dissonant strings
Give various response to each varying blast
-We rest.—A dream has power to poison sleep;
We rise.—One wandering thought pollutes the day
-We feel, conceive or reason, laugh or weep;
Embrace fond woe, or cast our cares away
