William of Conches (Template:Lang-la; Template:Lang-fr; c. 1090 – c. 1154), historically sometimes anglicized as William Shelley, was a medieval Norman-French scholastic philosopher who sought to expand the bounds of Christian humanism by studying secular works of classical literature and fostering empirical science. He was a prominent Chartrain (member of the School of Chartres). John of Salisbury, a bishop of Chartres and former student of William's, refers to William as the most talented grammarian of the time, after his former teacher Bernard of Chartres.

Life

William was born around 1085–1090 in a small village near Évreux, Normandy. From his surname, that village is generally taken to have been Conches although it was possibly nearby Tilleul instead, the location of his later grave. At the time, Normandy was still uneasily controlled by Norman England in notional homage to France. William studied under Bernard of Chartres in Chartres, Blois, and became a leading member of the School of Chartres, early Scholastics who formed part of the 12th-century Renaissance. Less focused on Aristotle and medieval dialectic than Peter Abelard and his students at the University of Paris, the Chartrians primarily aimed to reconcile Christian morality and legend with Platonic philosophy, chiefly with reference to the Book of Genesis and Plato's Timaeus.

William began teaching around 1115–1120 and was primarily based in Paris and Chartres. He composed his De Philosophia Mundi around the period 1125 to 1130. He taught John of Salisbury at Chartres in 1137 and 1138, and John later considered him the most accomplished grammarian of his time or just after his master Bernard. John describes his method of teaching in detail, noting it followed Bernard and both followed Quintilian's Institutio Oratoria. There were lectures on classical with questions on parsing, scansion, and composition. Students practiced writing prose and poetry on classical models and undertook frequent discussion on set subjects with the aim of developing fluency and cultivating elegant diction. William of St. Thierry, who had previously encouraged Bernard of Clairvaux to prosecute Abelard, wrote another letter to the same cleric "on the errors of William of Conches" (De Erroribus Guillelmi de Conchis) in 1141, complaining of the modalist view of the Trinity implicit in the Philosophia. William had not explicitly upheld with Bernard Sylvestris that Plato's "world soul" (Template:Lang-la; Template:Lang-grc-gre, psychḕ toû kósmou) was essentially identical with the Holy Spirit, but had discussed the idea as a possibly valid reading. With Abelard's writings successfully condemned by Bernard at the Council of Sens for a litany of heresies the same year, William withdrew from public teaching. William's exemption from prosecution alongside his production of more orthodox revisions of some of his previous works, his departure from public teaching, and the bitterness of some of his discussion of clerics in his later works is suggestive of a compromise worked out between Bernard and his friend the papal legate Geoffroy de Lèves, who as bishop of Chartres would have overseen its affiliated school, but there is no explicit surviving record of such an arrangement.

William then sought the patronage and protection of Geoffrey Plantagenet, the learned and powerful count of Anjou. In 1143 or 1144, he became the personal tutor of Geoffrey's 9 to 11-year-old son Henry, later King Henry II of England. He also tutored Henry's brothers in the period from 1146 to 1149 and composed his Dragmaticon, a revision of his Philosophia in the form of a dialogue, sometime between 1144 and 1149. He dedicated it to Geoffrey. There are some hints in his works that he may have resumed teaching, possibly in Paris, during the 1150s but these are inconclusive.

He died in 1154 or shortly afterward, probably at Paris or the environs of Évreux. The funeral slab with his effigy has been moved from its original location at St Germanus's Church, Tilleul, to St Faith's Church in Conches.

Works

The number and attribution of works by William of Conches has been a persistent problem of medieval bibliography, as has the inaccuracy of the many manuscripts and editions.

It is now certain that William wrote two editions of the encyclopedic De Philosophia Mundi ("On the Philosophy of the World"), although it was previously variously attributed to Bede, William of Hirsau, Honorius of Autun, and Hugh of St Victor. Likewise, he wrote one edition of the related dialogue Dragmaticon, whose neological name has been variously emended to Dramaticon ("A Dramatization") and to Pragmaticon Philosophiae ("The Business of Philosophy") although William himself understood his transliteration of dramatikón (δραματικόν) as meaning an interrogation (interrogatio) or question-and-answer format. The Dragmaticon continues to be largely considered a bowdlerized or revised edition of the Philosophia; however, from the 1980s, scholars have reconsidered this attitude, noting that only about 3–5% of the earlier work was removed against a rough doubling of content, with numerous additional Greek and Arabic sources. A "lost" treatise Magna de Naturis Philosophia ("The Great Philosophy of Nature"), considered his true masterwork by his early biographers and sometimes still attributed to him, was the product of an extensive series of mistakes based on a poor edition of Vincent of Beauvais's Mirror of Nature that began with an extract from William of Conches's work.

William is also credited with numerous glosses on classic texts. He wrote surviving overviews of commentaries on Boethius's Consolation of Philosophy (Glosae super Boetium) and Plato's Timaeus (Glosae super Platonem); 2 editions of his own commentary on Priscian's Institutes of Grammar (Glosae super Priscianum); and one or two editions of commentary on Macrobius's Commentary on the Dream of Scipio (Glosae super Macrobium); his other works also mention now-lost commentaries on Martianus Capella's On the Marriage of Philology and Mercury and on Boethius's On Education in Music. He was probably responsible for several surviving glosses of Juvenal's Satires and is credited by some with a lost commentary on Vergil's Aeneid. He is sometimes still credited as the author of Moralium Dogma Philosophorum ("Philosophers' Moral Teachings"), the first medieval treatise on philosophical ethics, although this attribution is more suspect. The gloss of the Gospels (Glosa super Evangelia) credited to him was either entirely spurious or a misattribution of content from William of Auvergne.

William's generally credited works are marked by special attention to cosmology and psychology and were among the first works of medieval Christian philosophy to devote considerable attention to Islamic philosophy and science, using the Latin translations produced by Constantine the African. They display the humanism, Platonism, and affinity for the natural sciences of other members of the School of Chartres, with whom William shared the tendency of analyzing his source texts through the lens of "covering" or "shieding" (integumentum) treating any apparent contradictions or heretical content within them as an allegory or metaphor for an underlying accurate and orthodox truth. In the passage of Plato's Timaeus stating that souls existed in the stars before birth, William opined that he really meant "nothing heretical, but the most profound philosophy sheltered in the covering of the words". He then glossed Plato's intended meaning as simply noting the accepted importance of astrology on human fate.

De Philosophia Mundi

William's chief work appears in manuscript as his Philosophy (Philosophia) but, owing to mistakes in transmission and comprehension, various recensions were published for centuries as Bede's Four Books of the Philosophy of the Elements (Elementorum Philosophiae Libri Quatuor), William of Hirsau's Three Books of Philosophical and Astronomical Instruction (Philosophicarum et Astronomicarum Institutionum Libri Tres), and Honorius of Autun's Four Books on the Philosophy of the World (De Philosophia Mundi Libri Quatuor). A separate recension rediscovered in the 20th century was a Compendium of Philosophy (Compendium Philosophiae) attributed to Hugh of St Victor. The "Honorius" recension being the most complete, it has become the general name for the work in modern scholarship. The correct title and attribution were finally discovered in 1722 by Remi-Casimir Oudin with additional points and considerations added by Charles Jourdain in 1838 and Jean-Barthélemy Hauréau in 1858. It has also been known as William's Lesser Philosophy (Philosophia Minor) by comparison with the misnamed, miscredited, and misdescribed Magna de Naturis Philosophia. More recently, Gregor Maurach produced partial and complete editions of the text compiled from numerous manuscripts before it was fully realized that William had composed two separate editions, one during his youth and another revised around the time of Bernard's attacks on Abelard and others. According to Paul Edward Dutton's tally, 68 manuscripts of the original edition and 16 of the revised edition are currently known to exist.

The first edition of the De Philosophia Mundi was divided into four books, covering physics, astronomy, geography, meteorology, and medicine. The revised edition expanded the first book and divided it into three parts, making up six books altogether.

Discussing cosmology, William elaborates a geocentric universe. The terrestrial atmosphere is said to become less dense and colder as altitude increases. Its circulation is also compared to ocean currents. By the level of the moon, it has been replaced by the ether; the sun, moon, and five known planets followed their own motions while the fixed stars simply followed the motion of the ether itself. William presented three arguments for the existence of God based on the order of the world. He identified the parts of the Trinity with their attributes: God the Father as Power, Jesus the Son as Wisdom, and the Holy Spirit as Will or Goodness. Unlike Abelard, he did not argue that God could not avoid creation but he did tend to limit the direct acts of God to creation, with angels otherwise intermediary between Heaven and this world.

William glosses the composition of the world as rooted in the four elements but follows Constantine the African in considering an element "the simplest and minimum part of any body—simple in quality, minimum in quantity". Therefore, he does not identify elemental fire, air, water, or earth with any of the composite forms in which they are experienced by humans. He argues that the pure forms of the elements cannot be perceived but only grasped by reason applied to abstracted division of sensible forms. He considers that these pure elements are defined by their intrinsic temperature and moistness: earth was cold and dry, water cold and moist, air hot and moist, and fire hot and dry. These traits compelled the atoms into certain movements, which he discusses in Aristotelian terms.

The discussion of medicine deals chiefly with procreation and childbirth. This work influenced Jean de Meung, the author of the second part of the Roman de la Rose. William's discussion of psychology was expressed in terms of the soul, which he considered to provide various powers when joined to the body. He believed that sense perception derived from the world, reason from God, and that memory preserved them both.

Notes

1. William's birth was placed in Cornwall by John Bale on the supposed authority of John Boston of Bury St Edmunds Abbey, although Mary Bateson and others have considered this implausible.
2. He has sometimes been identified as the "Guillaume de Conques" listed as born 1080 and died 1154 who figures in the list of faculty of the medical school of the University of Montpellier, although this remains a minority opinion.
3. ... Willelmus de Conchis, grammaticus, post Bernardum Carnotensem, opulentissimus ...
4. Elementum ergo, ut ait Constantinus in Pantegni, est simpla et minima pars alicuius corporis—simpla ad qualitatem, minima ad quantitatem.
5. Si ergo illis digna velimus imponere nomina, particulas praedictas dicamus "elementa", ista quae videntur "elementata".
6. Quae elementa numquam videntur, sed ratione divisionis intelliguntur.
