He was very fond of his own name, and, like young and uneducated people, wrote or carved it anywhere; later placed near it that of a new love, Annette, and afterward on finding the tree he shed tears, melted toward her, and made an idyl. He was also seized with a passion of teasing her and dominating over her devotedness with wanton and tyrannical caprice, venting upon her the ill humor of his disappointments, and grew absurdly jealous and lost her after she had borne with him with incredible patience and after terrible scenes with her by which he gained nothing. Frenzied by his loss, he began to abuse his physical nature and was only saved from illness by the healing power of his poetic talent; the "Lover's Caprice" was written with the impetus of a boiling passion. In the midst of many serious events, a reckless humor, which was due to the excess of life, developed which made him feel himself superior to the moment, and even to court danger. He played tricks, although rarely with premeditation. Later he mused much upon the transient nature of love and the mutability of character; the extent to which the senses could be indulged within the bounds of morality; he sought to rid himself of all that troubled him by writing song or epigram about it, which made him seem frivolous and prompted one friend to seek to subdue him by means of church forms, which he had severed on coming to Leipzig. By degrees he felt an epoch approaching when all respect for authority was to vanish, and he became suspicious and even despairing with regard to the best individuals he had known before and grew chummy with a young tutor whose jokes and fooleries were incessant. His disposition fluctuated between gaiety and melancholy, and Rousseau attracted him. Meanwhile his health declined until a long illness, which began with a hemorrhage, caused him to oscillate for days between life and death; and convalescence, generally so delightful, was marred by a serious tumor. His father's disposition was stern, and he could become passionate and bitter, and his mother's domesticity made her turn to religion, so that on coming home he formed the acquaintance of a religious circle. Again Goethe was told by a hostile child that he was not the true son of his father. This inoculated him with a disease that long lurked in his system and prompted various indirect investigations to get at the truth, during which he compared all distinguished guests with his own physiognomy to detect his own likeness.
