Renaissance humanism

• 1. Introduction

  ›

  Renaissance humanism began with a simple but radical conviction: that the study of ancient Greece and Rome could make people better. Not just smarter, but morally better. Citizens who could argue clearly, write persuasively, and engage in public life with virtue and prudence. That conviction took root in the city-states of Italy in the 14th century and spread across Western Europe over the next two hundred years, reshaping education, politics, religion, and philosophy along the way.

  What made this movement unusual was its ambition. Humanism was set up by a small elite who had access to books and education, yet it was intended as a cultural movement to influence all of society. It was a program to revive the literary legacy and moral philosophy of Greco-Roman civilization. And while it was deeply Christian in spirit, it looked to pagan writers for guidance on how to live.

  The questions this story raises are worth sitting with. How did a literary revival become a force that shaped the Reformation, modern international law, and even existentialist philosophy? Who were the scholars, churchmen, and chancellors who carried it forward? And why did the name these thinkers used for their own project, studia humanitatis, get replaced by a word they never used themselves?

• 2. The Studia Humanitatis

  ›

  Around the middle of the 14th century, Italian scholars began using a specific Latin phrase, studia humanitatis, to describe a particular kind of learning. At first, the term was used quite narrowly. According to scholar Benjamin G. Kohl, it appeared initially as praise of the cultural and moral attitudes expressed in Cicero's Pro Archia poeta, a speech dated to 62 BCE.

  Tuscan humanist Coluccio Salutati picked up the phrase in the 1370s, broadening it to mean culture and learning as a guide to moral life, with a special emphasis on rhetoric and oration. Over time Salutati himself shifted again, eventually viewing the studia humanitatis as a means of editing and restoring ancient texts and even of understanding scripture.

  It was not until the beginning of the 15th century, the quattrocento, that the term became associated with specific academic disciplines. Pier Paolo Vergerio, in his De ingenuis moribus, stressed rhetoric, history, and moral philosophy as tools of moral improvement. The phrase then spread through Bologna and Padua, where universities began offering courses in these subjects alongside Latin poetry.

  The fullest early definition came in a letter from Tommaso Parentucelli to Cosimo de' Medici, recommending books for his library. Parentucelli wrote of studies "insofar as they consist of grammar, rhetoric, history and poetry, and also ethics." That formulation, grammar, rhetoric, history, poetry, and moral philosophy, became the standard account of what the studia humanitatis contained. What it conspicuously excluded was logic, which had been central to medieval scholastic education.

• 3. Fathers and Collectors

  ›

  Petrarch was dubbed the Father of Humanism because he was the first to encourage the study of pagan civilizations and the teaching of classical virtues as a means of preserving Christianity. He was also one of the great collectors of antique manuscripts, a passion he shared with Giovanni Boccaccio, Coluccio Salutati, and Poggio Bracciolini.

  Many of these early humanists held positions in the Catholic Church or in civic government. Petrarch himself was in holy orders. His disciple Salutati served as Chancellor of Florence, a post that gave him access to book copying workshops. This overlap between humanist scholarship and institutional power was not incidental. It meant that the movement had resources and reach from very early on.

  By the mid-15th century, many of the upper classes in Italy had received humanist educations, sometimes alongside traditional scholastic ones. Some of the highest Catholic officials were active patrons of humanist scholarship. Cardinal Basilios Bessarion, a convert from Greek Orthodoxy who was considered for the papacy, was one of the most learned scholars of his time and built an important library. Several humanist popes followed, among them Aeneas Silvius Piccolomini, who became Pope Pius II and wrote a treatise on The Education of Boys.

  A decisive infusion of Greek learning arrived after 1453, when Byzantine Greek scholars fled west following the fall of Constantinople. Figures including Gemistus Pletho, George of Trebizond, Theodorus Gaza, and John Argyropoulos brought with them a deeper familiarity with ancient Greek texts than most Latin scholars possessed. Their knowledge complemented the Latin manuscripts Petrarch's generation had found in monastic libraries.

• 4. Humanism Crosses Borders

  ›

  Spanish humanism found its first great exponent in Francisco de Vitoria, whose work on the rights of Spanish subjects in the Americas became seminal and earned him the title father of modern international law. He founded the School of Salamanca, and Antonio de Nebrija became one of its principal members.

  A circle of humanists also gathered around Charles V, who was simultaneously King of Spain and Holy Roman Emperor. That circle included Alfonso and Juan de Valdés, Juan Luis Vives, and Luisa Sigea. Charles appointed the noted humanist Mercurino di Gattinara as his chancellor. The Valdés brothers, Gattinara, and Antonio de Guevara shared a vision of restoring a Christian, universal Roman Empire, an idea the source traces to Dante Alighieri's Monarchia.

  Spain's ongoing wars, including the Italian Wars and the Ottoman-Habsburg Wars, shaped a militarized variant of humanism known as las armas y las letras, meaning the weapons and the letters. This conception was first set down formally in Charles's court by Baldassare Castiglione.

  North of the Alps, humanism spread after 1500 alongside the large-scale adoption of printing. In France, Guillaume Budé, who lived from 1467 to 1540, applied Italian philological methods to the study of antique coinage and to legal history, producing a detailed commentary on Justinian's Code. Budé served as a diplomat for Francis I and helped found the Collège des Lecteurs Royaux, later the Collège de France. Francis I's own sister, Marguerite de Navarre, was a poet, novelist, and religious mystic who protected a circle of vernacular writers that included Clément Marot, Pierre de Ronsard, and François Rabelais.

• 5. Paganism, Christianity, and Epicurus

  ›

  In 1417, Poggio Bracciolini discovered a manuscript of Lucretius's De rerum natura, a text that had been lost for centuries. It contained a full account of Epicurean doctrine. At the time, Renaissance scholars confined their remarks mostly to Lucretius's grammar and syntax. The philosophical content went largely undiscussed.

  Not until 1564 did French commentator Denys Lambin, who lived from 1519 to 1572, address the ideas directly, declaring in his preface that he regarded Lucretius's Epicurean philosophy as fanciful, absurd, and opposed to Christianity. Lambin's preface set the interpretive tone for subsequent centuries.

  Yet the relationship between humanism and Epicureanism was more complicated than that dismissal suggests. The humanist Lorenzo Valla put a defense of Epicureanism in the mouth of a character in one of his dialogues. Scholar Charles Trinkhaus argues that this was not a sincere defense but a rhetorical ploy, designed to refute Stoicism, which Valla considered equally inferior to Christianity.

  Erasmus, whom the source calls the Prince of humanists, picked up Valla's argument in The Epicurean. In that work, Erasmus argued that the most genuinely Epicurean people were the righteous and godly. He went further, suggesting that Christ himself deserved the name Epicurean because the Greek word epikouros means helper. This passage captures how humanists characteristically worked: they found ways to read pagan classical philosophy as consistent with, or even anticipating, their understanding of Christianity.

  Marsilio Ficino, whose Latin translations of Plato were still in use in the 19th century, pursued the same strategy with Platonism, attempting to reconcile it with Christianity along lines suggested by Church Fathers Lactantius and Saint Augustine. Pico della Mirandola pushed still further, trying to build a syncretism spanning multiple religions and philosophies. Church authorities rejected his effort because of his views on magic.

• 6. The Reformation and After

  ›

  A number of humanists joined the Reformation movement outright. Philipp Melanchthon, Ulrich Zwingli, Henry VIII, John Calvin, and William Tyndale all moved into leadership roles within Protestant churches. Others, like Jacques Lefèvre d'Étaples, supported the Reformation while remaining Catholic.

  Even Erasmus, described in the source as a moderate Catholic, risked being declared a heretic for his perceived criticism of the institutional church. The sharply confrontational atmosphere that followed the Reformation made humanist scholarship politically dangerous in ways it had not been before.

  The Council of Trent, which met from 1545 to 1563, initiated the Counter-Reformation and imposed a strict Catholic orthodoxy grounded in scholastic philosophy, the very tradition humanism had challenged. Yet the educational systems developed by Jesuits continued to run on humanist lines, preserving the studia humanitatis within institutions that officially opposed the movement's more radical impulses.

  The historian Sir John Hale issued a caution that still matters for understanding what Renaissance humanism was and was not. He warned against assuming a direct link between it and modern secular humanism. Renaissance humanists, he wrote, worked to supplement Christianity through their patient excavation of ancient wisdom, not to contradict it. Most were Christians first. Their disagreement with medieval scholasticism was about method and emphasis, not about faith itself.

• 7. Scholars Argue the Legacy

  ›

  Hans Baron, who lived from 1900 to 1988, coined the term civic humanism in the 1920s, basing it largely on his studies of Leonardo Bruni. Baron's central claim, laid out in his major work The Crisis of the Early Italian Renaissance, was that a distinct republican strand of humanism emerged around 1402, in the wake of Florence's great struggles with Visconti-led Milan in the 1390s.

  The Baron Thesis attracted criticism almost immediately. By the 1960s, historians Philip Jones and Peter Herde were arguing that the republics Baron praised were far less liberty-driven than he believed, and practically as undemocratic as monarchies. James Hankins added that humanists employed by oligarchies and those working for princes showed no notable difference in political values. Hankins concluded that the political reform program at humanism's core was not republican in the ideological sense Baron meant.

  Two other scholars, Eugenio Garin and Paul Oskar Kristeller, collaborated throughout their careers while disagreeing fundamentally about what humanism was. Kristeller held that the humanists were professional rhetoricians. Their contributions to philosophy were incidental to their core work in grammar, rhetoric, poetry, history, and ethics. Garin took the opposite view, arguing that philosophy itself evolves with the practices of the thinkers of any given period, making the humanists' break from Scholasticism a genuinely philosophical act.

  That debate intersected with a broader conversation happening outside Renaissance studies. In 1946, Jean-Paul Sartre published a work titled L'existentialisme est un humanisme, outlining his view that existence comes before essence. Martin Heidegger responded by both defining humanism and criticizing the Italian Renaissance variant explicitly. Kristeller, who had studied under Heidegger, also discounted Renaissance humanism as philosophy. Garin's Der italienische Humanismus was published alongside Heidegger's response to Sartre, in what one scholar describes as an attempt to stage a pre-emptive confrontation between historical humanism and philosophical neo-humanisms.
