But if we turn from this laborious and often irrelevant search for common ideas and parallel passages to the actual facts of Nietzsche's intellectual development, we shall find, perhaps, that his ancestry ran in two streams, the one coming down from the Greeks whom he studied as school-boy and undergraduate, and the other having its source in Schopenhauer, the great discovery of his early manhood and the most powerful single influence of his life. No need to argue the essentially Greek color of Nietzsche's apprentice thinking. It was, indeed, his interest in Greek literature and life that made him a philologist by profession, and the same interest that converted him from a philologist into a philosopher. The foundation of his system was laid when he arrived at his conception of the conflict between the Greek gods Apollo and Dionysus, and all that followed belonged naturally to the working out of that idea. But what he got from the Greeks of his early adoration was more than a single idea and more than the body of miscellaneous ideas listed by the commentators: it was the Greek outlook, the Greek spirit, the Greek attitude toward God and man. In brief, he ceased to be a German pastor's son, brought up in the fear of the Lord, and became a citizen of those gorgeous and enchanted isles, much as Shelley had before him. The sentimentality of Christianity dropped from him like an old garment; he stood forth, as it were, bare and unashamed, a pagan in the springtime of the world, a _ja-sager_. More than the reading of books, of course, was needed to work that transformation--the blood that leaped had to be blood capable of leaping--but it was out of books that the stimulus came, and the feeling of surety, and the beginnings of a workable philosophy of life. It is not a German that speaks in "The Antichrist," nor even the Polish noble that Nietzsche liked to think himself, but a Greek of the brave days before Socrates, a spokesman of Hellenic innocence and youth.
