This collection of personal correspondence provides a rare window into the private life of the toweringnineteenth-century philosopher.Friedrich Nietzsche was the most iconoclastic philosopher of modern history. He is known to the world as the scathingly brilliant provocateur behind such foundational works as Thus Spoke Zarathustra, Beyond Good and Evil, and Twilight of the Idols. This was Nietzsche as he addressed himself to the public. But in this collection of his personal letters, we discover a very different man: Nietzsche the devoted son; the caring friend; the university student; the shy and distant lover. Comprised of correspondence between Nietzsche’s inner circle—including several revelatory letters to his sister—Unpublished Letters gives readers a never-before-seen look into the philosopher’s daily life.
