With Wordsworth, mortality is often just under the surface, as it was with Keats, another child of his time, who believed, because of the Enlightenment, that we are material beings in a material universe and that we must just accept that fate. We are mortal, but with no divine shoulder to lean on, and we will never understand the deepest truths, which, contrary to all the protestations of the Enlightenment, neither reason nor science can reach. Keats had a tragic sense of life. He is recognizably a Romantic; there is no Enlightenment Utopia waiting for him.
