To the reader who knows Nietzsche, who has studied his Zarathustra and understood it, and who, in addition, has digested the works entitled Beyond Good and Evil, The Genealogy of Morals, The Twilight of the Idols, and The Antichrist, - to such a reader everything in this volume will be perfectly clear and comprehensible. In the attack on Strauss he will immediately detect the germ of the whole of Nietzsche's subsequent attitude towards too hasty contentment and the foolish beatitude of the "easily pleased"; in the paper on Wagner he will recognize Nietzsche the indefatigable borer, miner and underminer, seeking to define his ideals, striving after self-knowledge above all, and availing himself of any contemporary approximation to his ideal man, in order to press it forward as the incarnation of his thoughts. Wagner the reformer of mankind! Wagner the dithyrambic dramatist!-The reader who knows Nietzsche will not be misled by these expressions. To the uninitiated reader, however, some words of explanation are due, not only in regard to the two papers before us, but in regard to Nietzsche himself. Friedrich Wilhelm Nietzsche was a 19th-century German philosopher, poet, composer and classical philologist. He wrote critical texts on religion, morality, contemporary culture, philosophy and science, displaying a fondness for metaphor, irony and aphorism.
