In his preliminary path-finding Nietzsche concerned himself much with the history of specific ideas. He showed how the thing which was a sin in one age became the virtue of the next. He attacked hope, faith and charity in this way, and he made excursions into nearly every field of human thought--from art to primary education. All of this occupied the first half of the 70's. Nietzsche was in indifferent health and his labors tired him so greatly that he thought more than once of giving up his post at Basel, with its dull round of lecturing and quizzing. But his private means at this time were not great enough to enable him to surrender his salary and so he had to hold on. He thought, too, of going to Vienna to study the natural sciences so that he might attain the wide and certain knowledge possessed by Spencer, but the same considerations forced him to abandon the plan. He spent his winters teaching and investigating and his summers at various watering-places--from Tribschen, in Switzerland, where the Wagners were his hosts, to Sorrento, in Italy. At Sorrento he happened to take lodgings in a house which also sheltered Dr. Paul Rée, the author of "Psychological Observations," "The Origin of Moral Feelings," and other metaphysical works. That Rée gave him great assistance he acknowledged himself in later years, but that his ideas were, in any sense, due to this chance meeting (as Max Nordau would have us believe) is out of the question, for, as we have seen, they were already pretty clear in his mind a long while before. But Rée widened his outlook a great deal, it is evident, and undoubtedly made him acquainted with the English naturalists who had sprung up as spores of Darwin, and with a number of great Frenchmen--Montaigne, Larochefoucauld, La Bruyère, Fontenelle, Vauvenargues and Chamfort. Nietzsche had been setting down his thoughts and conclusions in the form of brief memoranda and as he grew better acquainted with the French philosophers, many of whom published their works as collections of aphorisms, he decided to employ that form himself. Thus he began to arrange the notes which were to be given to the world as "_Menschliches allzu Menschliches_" ("Human, All-too Human"). In 1876 he got leave from Basel and gave his whole time to the work. During the winter of 1876-7, with the aid of a disciple named Bernhard Cron (better known as Peter Gast) he prepared the first volume for the press. Nietzsche was well aware that it would make a sensation and while it was being set up his courage apparently forsook him and he suggested to his publisher that it be sent forth anonymously. But the latter would not hear of it and so the first part left the press in 1878.
