Final Discussion

Aristotelian Traditions and Japan's Christian Century

The Immortality of the Soul in Japan’s Christian Century (Ken Nejime)

Christianity was introduced in Japan by the Jesuit Francis Xavier in 1549. Upon his arrival, he was struck to learn that the local Buddhist monks denied the possibility of life after death. For his evangelical activity, Xavier opted to emphasize the doctrine of the immortality of the soul, which was determined as an article of faith at the Fifth Lateran Council (1513). The Jesuits who followed him continued to work in this direction. Several important studies have shown that Europe saw lively debates on the doctrine of the immortality of the soul among religious orders and leading philosophers during the Renaissance. Disputes on the same issue between the Jesuits and the Japanese Buddhists show a striking parallel. This paper will thus address the religious and cultural encounter between the West and Japan in this period.

Western Cosmology in Japan’s Christian Century (Ryuji Hiraoka)

It was during its “Christian Century” (1549–1650) that Japan first encountered Western natural philosophy via the Jesuit missionaries. This paper explores how and why these missionaries emphasized cosmology in their evangelical activities. My central argument is that the Jesuits considered cosmological knowledge a very effective “spiritual weapon” in the first stage of their conversion plan in Japan: 1) to convince the initiates on the superiority of Christianity over local religions by demonstrating the existence of God on a logical and rational ground, then 2) to instill more strictly Christian doctrines, and finally 3) to reach Baptism. Many textual evidences show that cosmological ideas were closely tied to the references to “divine design,” which are found in treatises on catechism. This was the distinctive character of the early Jesuit mission in Japan.

Martyrdom, Orientalism and Christian Imagery: Japan in Early Modern Spanish Culture (Jorge Ledo)

Scholars are increasingly challenging the traditional view of early modern Japan as an isolated realm, disconnected from the West. For example, interest in the mutual influence of cultures between Spain and Japan has materialized in a small, but significant, number of publications during the last decade. In my talk I will briefly introduce some key questions in this emerging field of interest. I will then tackle three emblematic aspects of the Spanish perception of Japan between 1550 and 1650: 1) the history of the Martyrs of Japan, whose concrete vision on the evangelical mission of the Spanish Crown often contrasted with that of the missionaries in the Americas; 2) the recreation and adaptation to European taste of some features of Japanese culture and aesthetics; and 3) the role of Japanese evangelizers in the New World.

Astrology, Dream Interpretation and Daemons in Cardano’s On My Life (Hiro Hirai and Emi Enomoto)

On My Life is the autobiography of the famous Milanese physician, Girolamo Cardano (1501–1576/77). It was posthumously published in Paris in 1643 by the editorship of the French scholar Gabriel Naudé (1600–1653). This piece of work, extremely complex and difficult to understand for modern readers, is richly illustrated by elements based on Cardano’s personal dream interpretations, and its structure borrows models from Greek astrology and medicine. It is also colored by his lifelong experience of phenomena related to his “guardian spirit,” which finally appeared in the guise of his father, Fazio. This paper tries to decipher these elements by using his other writings, namely the Commentary on Ptolemy’s Tetrabiblos (1554), On My Own Books (1557 and 1562), Books on Synesian Dreams (1562) and Dialogue between Girolamo and his Father Fazio (written ca. 1574).

On Deriving Life from the Heavens: Astrology, Medicine and Magic in Marsilio Ficino’s De vita (Darrel Rutkin)

Although it is well known that astrology played a significant role in Marsilio Ficino’s De vita libri tres, and especially its third book, the De vita coelitus comparanda, the full range of its astrological dimensions has never been satisfactorily explored. In this talk, I will move towards fulfilling this desideratum by describing the three main realms in which Ficino used astrological techniques and ideas towards a medical end—namely, practical astrology, astrological medicine and talismanic magic—within the context of his Platonizing articulation of astrology’s natural philosophical foundations.

Western Conceptions of Nature and Japan’s Christian Century

Tokyo, Saturday 20 July 2013

Session 1: Renaissance Philosophy and Medicine

Kuni Sakamoto, “Scaliger on Angels”

Julius Caesar Scaliger (1484–1558) expounded his cosmology in the Exoteric Exercises (Paris, 1557), which became a popular textbook of natural philosophy in transalpine countries from the end of the sixteenth century. There he argued that the movements of the celestial spheres were caused by cosmic intellects, which he identified with angels. Based on this assumption, he tackled various questions: Why are the heavenly movers called “intellects” and “angels”? In what respects are they different from God and sublunary beings? How do they move the celestial orbs? His discussion was carefully built on traditional angelology in accordance with his Aristotelian conception of the universe, which was conditioned by the controversy with Girolamo Cardano (1501–76). This paper examines Scaliger’s notions of angels and intellects in their historical context and provides basic information about how the celestial movements were explained at the threshold of the “New Astronomy.”

Darrel Rutkin, “Christoph Clavius and the Rejection of Astrology”

We now know with certainty that astrology was taught in the finest European universities, in Italy and elsewhere, from the middle of the 13th through at least the middle of the 17th century. A central and integrating feature of the curriculum, astrology was taught in different respects in three distinct scientific disciplines: mathematics, natural philosophy and medicine. It was also practiced throughout medieval, Renaissance and early modern European society at both university and court, including at the highest levels of politics and culture. How and why, then, was astrology deleted from this cultural and scientific centrality? In this talk, I will explore one piece of this puzzle, namely, the removal of astrology from its normal teaching in the mathematics course in the writings of Christoph Clavius (1538–1612), the influential educational theorist and textbook writer for the increasingly successful and international Society of Jesus, more popularly known as the Jesuits.

Hiro Hirai, “The Immortality of the Soul in Renaissance Medicine”

In the philosophical debates carried out by Renaissance physicians, Galen’s theory of the soul became one of the most important issues because his newly recovered texts, such as De formatione foetuum, contained crucial elements that were not reconcilable with the medieval understanding of Galen’s theory. These ideas then had to be verified according to a conception of the soul based on Aristotle’s teachings and Christian dogma. This paper examines the case of a debate between Italian humanist Nicolò Leoniceno (1428–1524) and humanistically trained French physician Jean Fernel (1497–1558) on Galen’s theory of the soul. The problem of the human soul’s immortality played a significant role in the development of their divergent interpretations.

Session 2: Renaissance Literature and Religion

Jorge Ledo, “Erasmus and Luis de Granada”

Yoshi Kato, “Melanchthon on Social Order between Plato and Aristotle”

The Peasants’ War of 1525 profoundly impacted Protestant reformer Philip Melanchthon’s concept of social order. Moving away from his earlier commitment to the Platonic ideal of social equality, he conceptualized both theologically and philosophically the eternal order between the ruler and the ruled, territorial princes and peasants. By closely examining Melanchthon’s Confutatio articulorum rusticanorum (1525) and his 24 theses on the Peasants’ War, Disputatio de iusticia carnali et civili (1525), a new light is shed on the theological background of his commentaries and summary of Aristotle’s Ethics, published since the late 1520s. By analyzing Melanchthon’s adaptation of the Aristotelian concept of distributive justice, this paper elucidates the need for sixteenth-century Protestant thought in general and of Melanchthon in particular to ideologically establish the concept of divinely sanctioned social order so as to prevent future occurrences of such catastrophic events as the Peasants’ War.

Hazuki Shimono, “Mythic Interpretation and Imagination in Francis Bacon”

Francis Bacon reveals the view on mythologies in De sapientia veterum that myths are not fantastic tales fabricated by the ancients, but intrinsically “religious” accounts with mysterious origins. Since allegories and metaphors placed in myths are veils intended for humans to uncover hidden meanings, he claims that myths provide a means for humans to communicate with deities. This communicative nature of myths will be the focus of this presentation, as I illustrate Bacon’s theology as well as his unique interpretation of the Promethean myth, which for him signified the centrality of humans in this world, and their need for advancement. Such justification of his philosophy will be examined in reference to his theory on imagination. While he was critical about excessive reliance on imagination in religious matters, he evaluates it as a powerful epistemic force that could sometimes topple the governance of reason.

Session 3: Japan’s Christian Century

Ken Nejime, “The Immortality of the Soul and Its Problem in Japan’s Christian Century: From Xavier to Valignano”

Christianity was introduced in Japan by the Jesuit Francis Xavier in 1549. Upon his arrival, he was struck to learn that the local Buddhist monks denied the possibility of life after death. For his evangelical activity, Xavier opted to emphasize the doctrine of the immortality of the soul, which was determined as an article of faith at the Fifth Lateran Council (1513). The Jesuits who followed him, until Alessandro Valignano, continued to work in this direction. While Europe saw lively debates on the doctrine of the immortality of the soul among religious orders and leading philosophers during the Renaissance, disputes on the same issue between the Jesuits and the Japanese Buddhists show a striking parallel. This paper identifies the afterlife (or absence thereof) as the most important issue in Japan’s Christian Century and addresses the country’s religious and cultural encounter with the West.

Ryuji Hiraoka, “Early Jesuit Cosmology in Japan (1549–1817)”

Jesuit missionaries introduced Western cosmology in Japan during the sixteenth century as a dialectical and strategic weapon in their conversion plan. Despite the severe persecution begun in 1614, their cosmological manuscripts survived and were transmitted, whereas Christian content was entirely cleansed. In the 18th century, some readers even reached the conclusion that they were not of Western origin, and others considered them as having Chinese roots. Moreover, an interesting interaction with specialists of Dutch texts took place at the end of the same century. Jesuit cosmology was thus preserved throughout the Edo period by way of a complex process in which Chinese and Dutch specialists intervened. This paper examines how early Jesuit cosmology in Japan was established, preserved and transformed.

Wolfgang Michel, “Prayers for the Soul, Powders, Ointments, and Cautery for the Body: Medical Interactions in 16th and 17th-Century Japan”

Studies on the Japanese reception of Western medicine often focus on Luis de Almeida’s missionary hospital in Funai (1557–87) and some aspects of “Southern-Barbarian-style surgery” as the country’s first response to Portuguese and Spanish influence. This paper revisits the circumstances under which this encounter occurred and the extent of its impact on practice and writings. Indeed the exchange of know-how was fairly balanced, in contrast to later centuries. While inducing a particular view of European medicine in Japan, this encounter during Japan’s “Christian Century” also stimulated Western observations of the Sino-Japanese system (pulse diagnosis, acupuncture, moxibustion, etc.). Although “Southern-Barbarian-style surgery” never achieved the status of a clear-cut paradigm like Western medicine, it provided the basis for the ready acceptance of “Red-Head-style surgery” after the Dutch East India Company moved its trading post to Nagasaki in 1640–41.
