This is not the only interpretation of this poem. Another approach would say that Coleridge's poem asserts that ever since original sin, mankind has longed to return to Eden and the god-given paradise. Coleridge seems to say that man does this in vain, because Nature thwarts all attempts at this and paradise is forever lost.
Consider this alternate interpretation, and locate evidence that could be used to justify its acceptance. Explain how Coleridge seems to indicate man's desire to return to Eden, and also how Nature always thwarts man's attempts. (Don't forget that human nature might also be considered part of nature.)
