Arthur Schopenhauer (1788-1860) is one of the most significant German philosophers and is renowned for his pessimistic outlook. The introduction by Volker Spierling provides a comprehensive overview of Schopenhauer's philosophy and presents all of his works individually, including the texts from his estate, such as his lectures. At the center is his main work: The World as Will and Representation. Spierling highlights the rich variety of critical and reflective perspectives in Schopenhauer's philosophy, which encompasses the broad horizons of both European and Eastern philosophy, thus countering one-sided interpretations.
