It should not, however, be supposed that because he found the philosophy of the moment so little to his taste he necessarily squandered his time; on the contrary, he turned to Aristotle and Spinoza for consolation, and therewith followed sundry lectures in magnetism, electricity, ichthyology, amphiology, ornithology, zoölogy, and astronomy, all of which he enlivened with rapid incursions to the rich granaries of Rabelais and Montaigne, and moreover gave no little time to the study of the religion and philosophy of India. It was at this time characteristic of the man, that while his appearance, wealth, and connections would have formed an open letter to the best society in Berlin, which was then heterogeneously agreeable, or even to the worst, which is said to have been charming, he preferred to pass his leisure hours in scrutinizing the animals in the Zoölogical Gardens, and in studying the inmates of the State Lunatic Asylum. In this _cità dolente_ his attention was particularly claimed by two unfortunates who, while perfectly conscious of their infirmity, were yet unable to master it; in proof of which, one wrote him a series of sonnets, and the other sent him annotated passages from the Bible. In the second year of his student life at Berlin the war of 1813 was declared, and Schopenhauer was in consequence obliged to leave the city before he had obtained his degree. He prepared, however, and forwarded to the faculty at Jena an elaborate thesis, which he entitled the Quadruple Root of Conclusive Reason,--a name which somewhat astounded his mother, who asked him if it were something for the apothecary,--and meanwhile prowled about Weimar meditating on the philosophy which he had long intended to produce. He visited no one but Goethe, took umbrage at his mother's probably harmless relations with Fernow, treated her to discourse not dissimilar to that which Hamlet had addressed to his own parent, received his degree from Jena, and then went off to Dresden, where he began to study women with that microscopic eye which he turned on all subjects that engaged his attention. The result of these studies was an essay on the metaphysics of love, which he thereupon attached to his budding system of philosophy; an axiom to the effect that women are rich in hair and poor in thought; and the same misadventure that befell Descartes. His life at Dresden was necessarily much less secluded than that to which he had been hitherto accustomed; he became an _habitué_ at the opera and comedy, a frequent guest in literary and social circles, and, as student of men and things, he went about disturbing draperies and disarranging screens, very much as any other philosopher might do who was bent on seeing the world.
