“Unless love is passion, it’s not love, but something else; and passion thrives not on satisfaction, but on impediment. What d’you suppose Keats meant when he told the lover on his Grecian urn not to grieve? ‘Forever wilt thou love, and she be fair!’ Why? Because she was unattainable, and however madly the lover pursued she still eluded him. For they were both imprisoned in the marble of what I suspect was an indifferent work of art.
