"So said Zarathustra" - perhaps the most famous and widely read work of Nietzsche. For Nietzsche himself, "Zarathustra" is the main work of life, dividing his creative biography into periods "before" and "after." The attitude of the philosopher to this work was exceptional. Indeed, the book carries energy so exceptional that it was felt not only by Nietzsche himself, but also by many generations of his readers. And therefore this book is the key to understanding all the texts of the great philosopher, because it "appeals not so much to comprehension with its head as to experience in the soul, which is the only thing that can form into a certain organ of perception necessary for comprehending all other Nietzsche books." No wonder it is with this work, often called the Nietzsche Bible, that we begin to publish the texts of the great German.
