The world is full of poetry. The air is living with its spirit and the waves dance to the music of its melodies, and sparkle in its brightness.

Percival’s lines present poetry not as something confined to books but as an animating principle permeating nature. “Air,” “waves,” “music,” and “brightness” fuse the senses—breath, motion, sound, and light—into a single vision of the world as inherently lyrical. The passage implies that poetic perception is a way of attending: if one is receptive, ordinary phenomena become expressive, rhythmic, and meaningful. It also reflects a Romantic-era tendency (strong in early- to mid-19th-century American verse) to treat nature as spiritually charged and aesthetically self-sufficient, with human art echoing patterns already present in the natural world.
