Final answer:
True, the main theme of William Wordsworth's 'I wandered lonely as a cloud' is finding joy in nature, as demonstrated by the vivid imagery of daffodils and the poet's deep emotional response.
Step-by-step explanation:
The statement "The main theme in William Wordsworth's poem, I wandered lonely as a cloud, is finding joy in nature" is true. Wordsworth's famous poem, also known as "Daffodils", explores the profound joy and peace the poet finds in the natural world. As the poem's speaker encounters a host of golden daffodils by the lake, beneath the trees, fluttering and dancing in the wind, he is mesmerized by their beauty. This encounter reflects the theme of finding solace and delight in nature, which is a central tenet of Romantic poetry. Moreover, the poem illustrates the lasting impact of such moments of communion with nature; the memory of the daffodils' dance brings comfort to the speaker in later moments of solitude.
