thomas de quincey, 1823: "o, mighty poet! thy works are not as those of other men, simply and merely great works of art; but are also like the phenomena of nature, like the sun and the sea, the stars and the flowers,—like frost and snow, rain and dew, hail-storm and thunder, which are to be studied with entire submission of our own faculties, and in the perfect faith that in them there can be no too much or too little, nothing useless or inert—but that, the further we press in our discoveries, the more we shall see proofs of design and self-supporting arrangement where the careless eye had seen nothing but accident!" "on the knocking at the gate in "macbeth"".
