In January 1872 Nietzsche published his first book, The Birth of Tragedy. It is really but a portion of a much larger work on Hellenism which he had always had in view from his earliest student days, and it may be said to have been prepared in two preliminary lectures delivered at Bâle, under the title of the "Greek Musical Drama," and "Socrates and Tragedy." The work was received with enthusiasm by Wagnerians; but among Nietzsche's philological friends it succeeded in rousing little more than doubt and suspicion. It was a sign that the young professor was beginning to ascribe too much importance to Art in its influence upon the world, and this the dry men of science could not tolerate.

Between 1873 and 1876, Nietzsche, while still at Bâle, published four more essays which, for matter and form, proved to be among the most startling productions that Germany had read since Schopenhauer's prime. Their author called these essays Thoughts out of Season, and his aim in writing them was undoubtedly the regeneration of German culture. The first was an attack on German Philistinism, in the person of David Strauss, the famous theologian of Tübingen, whom Nietzsche dubbed the "Philistine of Culture," and was calculated to check the extreme smugness which had suddenly invaded all departments of thought and activity in Germany as the result of the recent military triumph.

The second, The Use and Abuse of History, was a protest against excessive indulgence in the "historical sense," or the love of looking backwards, which threatened to paralyse the intelligence of Germany in those days. In it Nietzsche tries to show how history is for the few and not for the many, and points out how rare are those who have the strength to endure the lesson of experience.

In the third, Schopenhauer as Educator, Nietzsche pits his great teacher against all other dry-as-dust philosophers who make for stagnation in philosophy. The fourth, Richard Wagner in Bayreuth, contains Nietzsche's last word of praise as a friend of the great German musician. In it we already see signs of his revulsion of feeling; but on the whole it is a panegyric written with love and conviction.

The only one of the four Thoughts out of Season which created much comment was the first, concerning David Strauss, and this gave rise to a loud outcry against the daring young philologist.

Nietzsche had been very unwell throughout this period. Dyspepsia and headaches, brought on partly by overwork, racked him incessantly, and, in addition, he was getting ever nearer and nearer to a final and irrevocable breach with the greatest friend of his life—Richard Wagner. After obtaining leave from the authorities he went to Sorrento, where, in the autumn of 1876, he began work on his next important book, Human, All-too-human, the book which was to part him for ever from Wagner. In February 1878 the first volume was ready for the printer, and was published almost simultaneously with Wagner's Parsifal, which work, as is well known, was the death-blow to Nietzsche's faith in his former idol.

In Human, All-too-human, Nietzsche as a philosopher is not yet standing on his own legs, as it were. He is only just beginning to feel his way, and is still deeply immersed in the thought of other men—more particularly that of the English positivists. As a work of transition, however, Human, All-too-Human is exceedingly interesting, as are also its sequels Miscellaneous Opinions and Apophthegms (1879) and The Wanderer and his Shadow (1880). But in none of these, as the author himself admits, is there to be found that certainty of aim and treatment which characterised his later writings.

In 1879, owing to ill-health, Nietzsche was compelled to resign his professorship at the University of Bâle, and the spring of that year saw him an independent man with an annual pension of 3000 francs, generously granted to him by the Board of Management on the acceptance of his resignation. With this pension and a small private income derived from a capital of about £1400, he was not destitute, though by no means affluent, and when we remember that he was obliged to defray the expenses of publication in the case of almost every one of his books, we may form some idea of his actual resources.

From this time forward Nietzsche's life was spent in travelling and writing. Venice, Marienbad, Zürich, St. Moritz in the Ober-Engadine, Sils Maria, Tautenberg in Thuringia, Genoa, etc., etc. were among the places at which he stayed, according to the season; and during the year 1880 his health materially improved. In January 1881 he had completed the manuscript of the Dawn of Day, and is said to have been well satisfied with his condition.
