BERNARD OF CHARTRES (d. c. i 13o), not to be con fused with Bernard of Tours (Silvestris), was a scholastic philos opher, described by John of Salisbury as per f ectissimus inter Platonicos nostri saeculi. About II17, he was teaching at Char tres, which was then the centre of Platonism and Humanism. In he became chancellor of the Church of Chartres. Bernard left no writings, but from the Metalogicus of John of Salisbury we know that he was deeply interested in the study of the classics and that he was a Platonic realist. Apart from God and the Divine ideas, he held that the original principles of all things were created matter and f ormae nativae, the latter being meant as a reconciliation between Plato and Aristotle. William of Con ches and Gilbert de la Porree were friends of Bernard. (See SCHOLASTICISM.) BIBLIOGRAPHY.-E. Gilson, "Le platonisme de B. de Chartres" in Bibliography.-E.
