Suffering by nature or chance never seems so painful as suffering inflicted on us by the arbitrary will of another.
Arthur Schopenhauer was a German philosopher known for his influential work on metaphysics, aesthetics, and ethics. His philosophy, often characterized as pessimistic, explores the nature of human existence, the pursuit of happiness, and the power of will. Schopenhauer's ideas have had a profound impact on various fields, including philosophy, psychology, and literature, influencing thinkers such as Friedrich Nietzsche and Sigmund Freud.
