In the spring of 1803, then, he accompanied his parents to London, where, after spending some time in sight-seeing, he was placed in the school of Mr. Lancaster at Wimbledon. Here he remained for three months, from July to September, laying the foundation of his knowledge of the English language, while his parents proceeded to Scotland. English formality, and what he conceived to be English hypocrisy, did not contrast favourably with his earlier and gayer experiences in France, and made an extremely unfavourable impression upon his mind; which found expression in letters to his friends and to his mother.
On returning to Hamburg after this extended excursion abroad, Schopenhauer was placed in the office of a Hamburg senator called Jenisch, but he was as little inclined as ever to follow a commercial career, and secretly shirked his work so that he might pursue his studies. A little later a somewhat unexplainable calamity occurred. When Dantzic ceased to be a free city, and Heinrich Schopenhauer at a considerable cost and monetary sacrifice transferred his business to Hamburg, the event caused him much bitterness of spirit. At Hamburg his business seems to have undergone fluctuations. Whether these further affected his spirit is not sufficiently established, but it is certain, however, that he developed peculiarities of manner, and that his temper became more violent. At any rate, one day in April 1805 it was found that he had either fallen or thrown himself into the canal from an upper storey of a granary; it was generally concluded that it was a case of suicide.
