Of these four poems, "I Wandered Lonely as a Cloud" is the most direct example of a nature poem. The speaker shows his love of nature when he is made joyous by the sight of thousands of daffodils in front of a lake which seem to dance in a breeze. This memory cheers him later as he lies thoughtfully on his couch.
In "Ode on a Grecian Urn," Keats's speaker expresses great joy and even ecstasy at the "sylvan" (woodland) scene he sees on a Grecian urn. The urn depicts springtime, with "happy" trees in bloom and young people leaving the nearby city to attend a pagan festival in the countryside. The speaker wishes he could be one of the figures on the vase, forever young and forever happy in a natural setting.
In "The Chimney Sweeper," Blake depicts the idyllic childhood that the chimney sweeper Tom dreams of: it is a pastoral paradise, with green grass, a river, and shining sun. This scene is contrasted to the chimney sweeper's grim coffin-like existence amid the filth and misery of London.
In "Love's Philosophy," Shelley's speaker celebrates the natural world, especially the way various parts of nature intermingle and seem to "kiss" one another, which becomes a metaphor and model for how the speaker wishes his beloved would kiss him.
Only "The Chimney Sweeper" explicitly prefers nature over society. The others show an implicit appreciation for nature by emphasizing its beautiful and life-affirming qualities.
