William of Conches

William of Conches (c. 1090–after 1154) was a French scholastic philosopher. He sought to expand the bounds of Christian humanism by studying secular works of the classics and fostering empirical science. John of Salisbury, a bishop of Chartres and former student of William's, refers to William as the most talented grammarian after Bernard of Chartres.


He was born in Conches, Normandy. His teaching activity extended from c. 1120 to 1154, and about the year 1122 he became the tutor of Henry Plantagenet. It is possible, but uncertain, that he was teaching at Chartres before that. Warned by a friend of the danger implied in his Platonic realism as he applied it to theology, he took up the study of Islamic philosophy and physical science. When and where he died is a matter of uncertainty.

William devoted much attention to cosmology and psychology. Having been a student of Bernard of Chartres, he shows the characteristic Humanism, tendency towards Platonism, and taste for natural science which distinguish the "Chartrains". He is one of the first of the medieval Christian philosophers to take advantage of Islamic physical and physiological lore, to which he had access in the translations by Constantine the African.

William of St. Thierry, who had encouraged Bernard of Clairvaux to prosecute Abelard, in another letter to Bernard attacked William's "De philosophia mundi" for having a modalist view of the Holy Trinity. William in consequence revised some controversial parts in the "Dragmaticon".


There is a good deal of discussion regarding the authorship of the works ascribed to William. It seems probable, however, that he wrote the encyclopedic "De philosophia mundi" (or "Philosophia") and the related dialogue "Dragmaticon", as well as glosses on Plato's "Timaeus", on Boethius's "Consolation of Philosophy", on Priscian's "Institutiones grammaticae", and on Macrobius's "Commentary on the Dream of Scipio". He was probably also the author of a lost treatise "Magna de naturis philosophia". A work on ethics, the "Moralium dogma philosophorum", was attributed to him in the 1920s, but his authorship is now rejected by most scholars.

The "De philosophia mundi"

The "De philosophia mundi" is divided into four books, covering physics, astronomy, geography, meteorology and medicine.

William explains the world as composed of elements ("elementa"), which he defines as

the simplest and minimum part [s] of any body - simple in quality, minimum in quantity ["Elementum ergo, ut ait Constantinus in Pantegni, est simpla et minima pars alicuius corporis - simpla ad qualitatem, minima ad quantitatem" ("De philosophia mundi", Liber primus, capitulum XXII).] .

He identifies elements with the traditional four elements (fire, air, water, earth) but (following Constantine the African) not as they are perceived, since as such they are neither simple in quality nor minimum in quantity: earth, for example, contains something hot, something cold, something dry and something wet at the same time. Pure elements are not to be perceived, says William, but to be grasped by reason, through an abstract division of the sensible bodies ["Quae elementa numquam videntur, sed ratione divisionis intelliguntur" ("Ibidem").] . Each of these pure elements has two of the four basic qualities: earth is cold and dry, water is cold and humid, air is hot and humid and fire is hot and dry. The perceivable elements, called "elementata" ["Si ergo illis digna velimus imponere nomina, particulas praedictas dicamus «elementa», ista quae videntur «elementata»" ("Ibidem).] , are made of pure elements: the sensible earth especially of pure earth, the sensible water especially of pure water, and so on.

The discussion of meteorology includes a description of air becoming less dense and colder as the altitude increases, and William attempts to explain the circulation of the air in connection with the circulation of the oceans. 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".
