William Wordsworth often used repetition in his poetry to create rhythm and emphasize ideas.
For Romantic poets, which Wordsworth was as well, rhythm was of utmost importance and they would experiment a lot with words in order to create it. Wordsworth didn't value science much so you won't find any scientific facts in his poetry, he wrote with a lot of emotions, so logic isn't that important either, and neither is rationality but rather quite the opposite.
