Signs of deafness had given him great anxiety as early as 1778. For a long time he successfully concealed it from all but his most intimate friends. The touching document addressed to his brothers in 1802, and known as his "Will" should be read in its entirety. He reproached men for their injustice in thinking and calling him pugnacious, stubborn, and misanthropical when they did not know that for six years he had suffered from an incurable condition aggravated by incompetent doctors. He dwelled upon his delight in human society from which he had had so early to isolate himself, but the thought of which now filled him with dread as it made him realize his loss, not in music — but in all finer interchange of ideas. He requested that after his death his present doctor shall be asked to describe his illness and to append it to his document in order that at least then the world might be as far as possible reconciled with him He left his brothers property, such as it was, if more conventional than the rest of the document. During the last twelve years of his life, his nephew was the cause of most of his anxiety and distress. His brother, Kaspar Karl died in 1815, leaving a widow and a son. The boy turned out utterly unworthy of his uncle's persistent devotion and gave him every cause for anxiety. He failed in all his examinations, including an attempt to learn some trade in the polytechnic school, whereupon he fell into the hands of the police for attempting suicide, and after being expelled from Vienna, joined the army. Beethoven's utterly simple nature could neither educate nor understand a human being who was not possessed by the wish to do his best. His nature was passionately affectionate, and he has suffered all his life from the want of a natural outlet for it. He had often been deeply in love and made no secret of it; there was no one that was not honorable and respected by society as showing the truthfulness and self-control of a great man. Beethoven's orthodoxy in such matters has provoked the smiles of Philistines, especially when it showed itself in his objections to Mozart, Don Giovanni and the grounds for selecting the subject of Fidelio for his own opera. The last thing that Philistines will never understand is that genius is far too independent of convention to abuse it; and Beethoven's life, with all its mistakes, its grotesqueness, and its pathos, is as far beyond the shafts of Philistine wit as his art.
