Goethe himself was well aware of a congenital morbid strain in him which all through his life demanded careful control if he were to avert bodily and mental collapse. And at no period of his life did external conditions and inward experiences combine to put his self-control to a severer test than during these last years in Frankfort. Frankfort itself, as we shall see, had become more distasteful to him than ever, and his abiding feeling towards it, now as subsequently, was that he could not breathe freely in its atmosphere. On his return from Strassburg his father received him with greater cordiality than on his return from Leipzig, but the lack of real sympathy between them remained, and was undoubtedly one of the permanent sources of Goethe's discontent with his native town. With no interest in his nominal profession, he had at the same time no clear conception of the function to which his genius called him. Throughout these years in Frankfort he continued uncertain whether Nature meant him for a poet or an artist, and we receive the impression that his ambition was to be artist rather than poet. From the varied literary forms in which he expressed himself, also, we are led to infer that in the domain of literature he was still only feeling his way. If the diversity of his gifts thus distracted him, his emotional experiences, it will appear, were not more favourable to a settled aim and purpose. One paroxysm of passion succeeded another, with the result that he was eventually, in self-preservation, driven to make a complete breach with his past, and to seek deliverance in a new set of conditions under which he might attain the self-control after which he had hitherto vainly striven. This prolonged conflict with himself was doubtless primarily due to his own inherited temperament, but it was also in large measure owing to the character of the society and of the time in which the period of his youth was passed. Had he been born half a century earlier--that is to say, in a time when the current speculation was bound up with a mechanical philosophy, and when the limits of emotion were conditioned by strict conventional standards--he might have been a youth of eccentric humours, but the morbid fancies and wandering affections that consumed him could not have come within his experience. But by the time when he began to think and feel, Rousseau had written and opened the flood-gates of the emotions, and Sterne had shown how accepted conventions might appear in the light of a capricious wit and fancy which probed the surface of things. In Goethe's letters, which are the most direct revelation of his mental and moral condition during the period, the influence of Rousseau and Sterne is visible on every page, and the fact has to be remembered in drawing any conclusions as to the real state of his mind from his language to his various correspondents. The fashion of giving exaggerated expression to every emotion was, in fact, the
