Chapter 27 emphasises the importance of French sources in shaping Goethe’s thinking on all fronts. The formative role of French began in his early years, owing not least to the French occupation of Frankfurt, evolved during his time as a student in Leipzig and Strasbourg, and was supported throughout Goethe’s adult life by his voracious reading. The chapter considers Goethe’s attitude, by turns admiring and ambivalent, to the Enlightenment philosophes, Voltaire, Diderot and Rousseau, and highlights the significance of the liberal journal Le Globe for Goethe towards the end of his life.
