Friedrich Nietzsche was a brilliant German thinker who influenced most of the outstanding European philosophers and writers of the first half of the 20th century. With his characteristic paradoxical thought, profound psychological analysis, and vivid, captivating, and unique writing style, Nietzsche debunked the moral prejudices of all European culture. Nietzsche's book, 'The Will to Power,' was unfinished and was published after his death, reconstructed by his sister, E. Förster-Nietzsche, and archival staff. Nevertheless, this book came to be regarded as Nietzsche's magnum opus, became a global cultural event, and influenced not only philosophy but the entire history of the 20th century.
