Alexander Prescott-Couch in Aeon: In Human, All Too Human (1878),Friedrich Nietzsche wrote that ‘A lack of historical sense is the original failing of all philosophers.’ In accusing philosophy of lacking historical sense, Nietzsche was echoing broader trends in 19th-century thought. In comparison with the ‘philosophical’ 18th century, the 19th century is sometimes described as the ‘historical’ century, one in which investigation into more universal features of human reason gave way to increased focus on how particular historical trajectories influence language, culture and moral assumptions.
The 19th century is also what one might call the ‘philological century’. Philology is the critical study of written sources, including their linguistic features, history of reception and cultural context. Today, the term sounds outmoded, evoking dusty, learned tomes of fastidious source criticism. However, philology was a leading intellectual discipline in 19th-century Germany due to a flurry of methodological developments that revolutionised our understanding of ancient and sacred texts. New rigorous techniques of verifying sources were developed, merely speculative hypotheses were discouraged, more detailed comparative studies of language were conducted. While such methods were scholarly, sometimes bordering on scholastic, their application had significant cultural impact, spilling out of scholarly journals into broader public consciousness.
Nietzsche imbibed these trends as a young man. An all-round talented student (mathematics was a notable exception), he gained admittance as a 14-year-old to Schulpforta, one of the most prestigious humanistic schools in Germany. A training ground for scholars and teachers, the school’s specialty was classical antiquity, and Nietzsche received a rigorous education in Greek and Latin, read historical works by Voltaire and Cicero, and wrote philological treatises on topics such as the saga of Ermanarich and the Greek poet Theognis.
This philological education informed not only his early works that deal directly with Greek antiquity, such as The Birth of Tragedy (1872), but also his later books on morality and moral psychology. Appreciating this philological influence is crucial for understanding the significance of his philosophically most important work, On the Genealogy of Morality (1887),and the ‘genealogical’ method of philosophy it has inspired.
