What happened

Lorenzo Valla, one of the most important humanists of the 15th century, attacked scholastic-Aristotelian philosophy from a linguistic standpoint in his Repastinatio dialectice et philosophie, arguing that scholastic logic had grown barren and needed to be re-cultivated with the tools of rhetoric and grammar instead. Around the same period Valla used philological analysis, comparing the Latin text against known Latin usage of different eras, to demonstrate that the Donation of Constantine, a document long used to justify papal claims to temporal rule, was a medieval forgery rather than a genuine 4th-century imperial grant. He also compared Jerome's Latin Vulgate translation of the New Testament against the original Greek text, laying groundwork for critical biblical scholarship. Civic humanists more broadly, including Leonardo Bruni, who produced fresh Latin translations of Aristotle and other Greek texts directly from Greek rather than through medieval intermediary translations, championed a return to classical sources and rhetoric, the studia humanitatis, over the technical logic of the scholastic universities.

Why it matters

Valla's philology showed that careful attention to language and historical usage could overturn claims scholastic argument alone had left unchallenged for centuries, and the wider humanist turn toward classical texts and rhetorical education broke scholasticism's hold on European intellectual life, opening space for the more text-critical, historically minded philosophy that would follow in the Renaissance and early modern period.

How we know

Valla's works, including the Repastinatio and his treatise on the Donation of Constantine, survive and have been studied continuously since the Renaissance; his philological arguments against the Donation's authenticity have been independently confirmed by later historians examining the document's language and content.
