Eureka By Edgar Allan Poe "Eureka, Poe's testament, the synthesis of his analytic ideas, offers itself as a treatise on nothing less than cosmology. Having begun as a scientific lecture, it winds up as an apocalyptic revelation.... It may be read as a rationalistic counterstatement to the metaphysics of Transcendentalism, or as a pioneering experiment in the embryonic genre of science fiction.... 'Eureka!' is his heart-cry. 'I have found it!' he breathlessly seems to announce."
