"Der Wille zur Macht" (The Will to Power) is a posthumously published collection of Nietzsche's notes and unpublished writings, organized by his sister Elisabeth Förster-Nietzsche. Although Nietzsche did compile the notes and drafts titled "The Will to Power", it was not published during his lifetime. Instead, it was posthumously edited and published by his sister, Elisabeth Förster-Nietzsche, and Peter Gast in 1901. Due to the enormous size of the document, this was published in two different parts; this is Part I. Nietzsche's sister introduces the document, explaining the origins and development of Nietzsche's thoughts leading up to "The Will to Power. She describes how Nietzsche's ideas evolved over time, influenced by his earlier works such as "Thus Spoke Zarathustra. She shares personal anecdotes and reflections on how Nietzsche's experiences, especially during times of war, shaped his philosophy. Nietzsche discusses the origins of nihilism, focusing on the moral interpretation of existence and the decline of Christianity. He critiques how modern science, politics, and history contribute to the nihilistic worldview. Nietzsche defines nihilism as the devaluation of the highest values, where traditional beliefs and goals lose their meaning. He examines how nihilism manifests as both a philosophical position and a psychological state.
