As at Eton, so at Oxford, Shelley refused to keep the beaten track of prescribed studies, or to run in ordinary grooves of thought. The mere fact that Aristotle was a duty, seems to have disgusted him with the author of the Organon, from whom, had his works been prohibited to undergraduates, he would probably have been eager to learn much. For mathematics and jurisprudence he evinced a marked distaste. The common business of the English Parliament had no attraction for him, and he read few newspapers. While his mind was keenly interested in great political questions, he could not endure the trivial treatment of them in the daily press, and cared far more for principles than for the incidents of party warfare. Here again he showed that impatience of detail, and that audacity of self-reliant genius, which were the source of both his weakness and his strength. He used to speak with aversion of a Parliamentary career, and told Hogg that though this had been suggested to him, as befitting his position, by the Duke of Norfolk, he could never bring himself to mix with the rabble of the House. It is none the less true, however, that he entertained some vague notion of eventually succeeding to his father's seat. Combined with his eager intellectual activity, there was something intermittent and fitful in the working of his mental faculties. Hogg, in particular, mentions one of his habits in a famous passage, which, since it brings the two friends vividly before us, may here be quoted. "I was enable to continue my studies afterwards in the evening, in consequence of a very remarkable peculiarity. My young and energetic friend was then overcome by extreme drowsiness, which speedily and completely vanquished him; he would sleep from two to four hours, often so soundly that his slumbers resembled a deep lethargy; he lay occasionally upon the sofa, but more commonly stretched upon the rug before a large fire, like a cat; and his little round head was exposed to such a fierce heat, that I used to wonder how he was able to bear it. Sometimes I have interposed some shelter, but rarely with any permanent effect; for the sleeper usually contrived to turn himself, and to roll again into the spot where the fire glowed the brightest. His torpor was generally profound, but he would sometimes discourse incoherently for a long while in his sleep. At six he would suddenly compose himself, even in the midst of a most animated narrative, or of earnest discussion; and he would lie buried in entire forgetfulness, in a sweet and mighty oblivion, until ten, when he would suddenly start up, and, rubbing his eyes with great violence, and passing his fingers swiftly through his long hair, would enter at once into a vehement argument, or begin to recite verses, either of his own composition or from the works of others, with a rapidity and an energy that were often quite painful."
