Chapter 19 examines Goethe’s relationship to philosophy, which throughout his life was one of both interest and guarded distance. It considers the transformations which philosophy as a discipline underwent during his lifetime, details Goethe’s attitudes to intellectual developments in his own time, above all the work of Kant, and devotes particular attention to Spinoza, without whose inspiration Goethe’s work is unthinkable, even if it cannot be reduced to a Spinozist position. The chapter also emphasises the singularity of Goethe’s own thought, which was forever transforming any influences that it received, becoming a source of inspiration and critical reflection for contemporary and succeeding generations of philosophers.
