Renaissance philosophy


The designation "Renaissance philosophy" is used by scholars of intellectual history to refer to the thought of the period running in Europe roughly between 1355 and 1650. It therefore overlaps both with late medieval philosophy, which in the fourteenth and fifteenth centuries was influenced by notable figures such as Albert the Great, Thomas Aquinas, William of Ockham, and Marsilius of Padua, and early modern philosophy, which conventionally starts with René Descartes and his publication of the Discourse on Method in 1637.
Philosophers usually divide the period less finely, jumping from medieval to early modern philosophy, on the assumption that no radical shifts in perspective took place in the centuries immediately before Descartes. Intellectual historians, however, take into considerations factors such as sources, approaches, audience, language, and literary genres in addition to ideas. This article reviews both the changes in context and content of Renaissance philosophy and its remarkable continuities with the past.

Continuities

The structure, sources, method, and topics of philosophy in the Renaissance had much in common with those of previous centuries.

Structure of philosophy

Particularly since the recovery of a great portion of Aristotelian writings in the twelfth and thirteenth centuries, it became clear that, in addition to Aristotle's writings on logic, which had already been known, there were numerous others roughly having to do with natural philosophy, moral philosophy, and metaphysics. These areas provided the structure for the philosophy curriculum of the emerging universities. The general assumption was that the most 'scientific' branches of philosophy were those that were more theoretical and therefore more widely applicable. During the Renaissance too, many thinkers saw these as the main philosophical areas, with logic providing a training of the mind to approach the other three.

Topics in philosophy

Given the remarkable range of Aristotelian philosophy, it was possible to discuss all kinds of issues in medieval and Renaissance philosophy. Aristotle had treated directly problems such as the trajectory of missiles, the habits of animals, how knowledge is acquired, the freedom of the will, how virtue is connected with happiness, the relationship of the lunar and the sublunar worlds. Indirectly he had stimulated discussion on two points that were particularly of concern to Christians: the immortality of the soul and the eternity of the world. All of these continued to be of considerable interest to Renaissance thinkers, but we shall see that in some cases the solutions offered were significantly different because of changing cultural and religious landscapes.

Discontinuities

Having established that many aspects of philosophy were held in common during the Middle Ages and the Renaissance, it will now be useful to discuss in what areas changes were afoot. The same outline as above will be used, to show that within trends of continuity one can also find surprising differences.

Structure of philosophy

While generally the Aristotelian structure of the branches of philosophy stayed in place, interesting developments and tensions were taking place within them. In moral philosophy, for instance, a position consistently held by Thomas Aquinas and his numerous followers was that its three subfields were related to progressively wider spheres. Politics, Thomas thought, is more important than ethics because it considers the good of the greater number. This position came under increasing strain in the Renaissance, as various thinkers claimed that Thomas's classifications were inaccurate, and that ethics were the most important part of morality.
Other important figures, such as Francesco Petrarca , questioned the whole assumption that the theoretical aspects of philosophy were the more important ones. He insisted, for instance, on the value of the practical aspects of ethics. Petrarch's position, expressed both strongly and amusingly in his invective On His Own Ignorance and That of Many Others is also important for another reason: it represents the conviction that philosophy should let itself be guided by rhetoric, that the purpose of philosophy is therefore not so much to reveal the truth, but to encourage people to pursue the good. This perspective, so typical of Italian humanism, could easily lead to reducing all philosophy to ethics, in a move reminiscent of Plato's Socrates and of Cicero.

Method of philosophy

If, as mentioned above, scholasticism continued to flourish, the Italian humanists challenged its supremacy. As we have seen, they believed that philosophy could be brought under the wing of rhetoric. They also thought that the scholarly discourse of their time needed to return to the elegance and precision of its classical models. They therefore tried dressing philosophy in a more appealing garb than had their predecessors, whose translations and commentaries were in technical Latin and sometimes simply transliterated the Greek. In 1416–1417, Leonardo Bruni, the pre-eminent humanist of his time and chancellor of Florence, re-translated Aristotle's Ethics into a more flowing, idiomatic and classical Latin. He hoped to communicate the elegance of Aristotle's Greek while also making the text more accessible to those without a philosophical education. Others, including Nicolò Tignosi in Florence around 1460, and the Frenchman Jacques Lefèvre d'Étaples in Paris in the 1490s, tried to please the humanists either by including in their commentaries on Aristotle appealing historical examples or quotations from poetry, or by avoiding the standard scholastic format of questions, or both.

The driving conviction was that philosophy should be freed of its technical jargon so that more people would be able to read it. At the same time, all kinds of summaries, paraphrases, and dialogues dealing with philosophical issues were prepared, in order to give their topics a wider dissemination. Humanists also encouraged the study of Aristotle and other writers of antiquity in the original. Desiderius Erasmus, the great Dutch humanist, even prepared a Greek edition of Aristotle, and eventually those teaching philosophy in the universities had to at least pretend that they knew Greek. Humanists were not, however, great fans of the vernacular. There is only a handful of examples of dialogues or translations of Aristotle's works into Italian during the fifteenth century. Once it had been determined, however, that Italian was a language with literary merit and that it could carry the weight of philosophical discussion, numerous efforts in this direction started to appear, particularly from the 1540s onward. Alessandro Piccolomini had a programme to translate or paraphrase the entire Aristotelian corpus into the vernacular.
Other important figures were Benedetto Varchi, Bernardo Segni and Giambattista Gelli, all of them active in Florence. Efforts got underway to present Plato's doctrines in the vernacular as well. This rise of vernacular philosophy, which quite predated the Cartesian approach, is a new field of research whose contours are only now beginning to be clarified.

Topics in philosophy

It is very hard to generalize about the ways in which discussions of philosophical topics shifted in the Renaissance, mainly because to do so requires a detailed map of the period, something we do not yet have. We know that debates about the freedom of the will continued to flare up, that Spanish thinkers were increasingly obsessed with the notion of nobility, that duelling was a practice that generated a large literature in the sixteenth century.
Earlier histories gave perhaps undue attention to Pietro Pomponazzi's pronouncements on the immortality of the soul as a question that could not be resolved philosophically in a way consistent with Christianity, or to Pico della Mirandola's Oration on the Dignity of Man, as if these were signals of the period's increasing secularism or even atheism. In fact, the most successful compendium of natural philosophy in the period was authored by Frans Titelmans, a Franciscan friar from the Low Countries whose work has a very strong religious flavour. We must not forget that most philosophers of the time were at least nominal, if not devout, Christians, that the sixteenth century saw both the Protestant and the Catholic reformations, and that Renaissance philosophy culminates with the period of the Thirty Years' War. In other words, religion had a massive importance in the period, and one can hardly study philosophy without remembering this.

This is true among others for the philosophy of Marsilio Ficino, who reinterpreted Plato in the light of his early Greek commentators and also of Christianity. Ficino hoped that a purified philosophy would bring about a religious renewal in his society and therefore transformed distasteful aspects of Platonic philosophy into spiritual love, something later transformed by Pietro Bembo and Baldassare Castiglione in the early sixteenth century as something also applicable to relationships between men and women. Ficino and his followers also had an interest in 'hidden knowledge', mainly because of his belief that all of ancient knowledge was interconnected. Although Ficino's interest in and practice of astrology was not uncommon in his time, one should not necessarily associate it with philosophy, as the two were usually considered to be quite separate and often in contradiction with each other.
In conclusion, like any other moment in the history of thought Renaissance philosophy cannot be considered to have provided something entirely new nor to have continued for centuries to repeat the conclusions of its predecessors. Historians call this period the 'Renaissance' in order to indicate the rebirth that took place of ancient perspectives, sources, attitudes toward literature and the arts. At the same time, we realize that every re-appropriation is constrained and even guided by contemporary concerns and biases. It was no different for the period considered here: the old was mixed with and changed by the new, but while no claims can be made for a revolutionary new starting point in philosophy, in many ways the synthesis of Christianity, Aristotelianism, and Platonism offered by Thomas Aquinas was torn apart in order to make way for a new one, based on more complete and varied sources, often in the original, and certainly attuned to new social and religious realities and a much broader public.
