give me the theme of the poem the lake of innisfree

"The Lake Isle of Innisfree” expresses a set of desires familiar in the modern world: to escape, to achieve peace and solitude, to be at one with nature. Yeats says almost nothing in the poem about what he would like to escape from, but his reader can easily imagine the stressful conditions of modern, especially urban, life. Such desires have been common themes in Romantic literature since the beginning of the nineteenth century, and “Innisfree” is a good example of late nineteenth century Romanticism.
