1743 – 1819
Friedrich Heinrich Jacobi was a German philosopher best known for popularizing the term 'nihilism' and for his critique of Enlightenment rationalism. He argued that reason, taken to its logical conclusion, leads to atheism and fatalism, and that genuine knowledge of reality and God requires a leap of faith (Glaube). His Spinoza dispute with Mendelssohn reshaped late 18th-century German philosophy and influenced German Idealism and Romanticism.

Popularized the term 'nihilism' in his critique of Fichte's idealism
Authored 'Concerning the Doctrine of Spinoza in Letters to Herr Moses Mendelssohn'
