How did Arthur Schopenhauer influence Friedrich Nietzsche’s early thought?

Arthur Schopenhauer’s influence on Friedrich Nietzsche’s early thought was profound, particularly during the period when Nietzsche wrote The Birth of Tragedy and his Untimely Meditations.1

Nietzsche’s early work was heavily shaped by a Romantic perspective that drew directly from Schopenhauer’s philosophy. Key aspects of this influence include:1

• The Philosophy of Will: Nietzsche was significantly impacted by Schopenhauer’s concept of the "will"—a quasi-mystical life force that underlies all reality and remains inaccessible to pure reason.2
• Limitations of Reason: Like Schopenhauer, the young Nietzsche adopted a skeptical view of the intellect, agreeing that reason is incapable of grasping the true nature of reality.2
• Aesthetic Insight: Schopenhauer argued that while the will cannot be understood through concepts, it can be glimpsed through nonrational aesthetic experiences, such as music. This belief profoundly shaped Nietzsche’s early aesthetic theories and his association with the composer Richard Wagner.21

Nietzsche eventually moved away from this early Romanticism and Schopenhauerian influence, beginning with his work Human, All-Too-Human, where he shifted toward an embrace of reason and science.1
