As to the study of Literature, care should be used in selecting the best authors. Bernard, he reports, "always said that unnecessary reading should be avoided, and that the writings of illustrious authors were sufficient; since to study whatever all that the most contemptible men have ever said results in too great torture or in idle boasting, and hinders and even overwhelms the intelligence, which is better left empty for other writings." The reading chosen was classical Latin literature; "in this reverent dependence upon the ancients, lies the main peculiarity of the school of Chartres," which under Bernard and his brother "enjoyed a peculiar distinction, continually growing until it became almost an unapproached pre-eminence among the schools of Gaul."[12] This reading is in turn a preparation for Philosophy. "He who aspires to Philosophy should understand reading, teaching and reflection, together with practice in good works." "Search Virgil and Lucan, and there, no matter of what philosophy you are professor, you will find it in the making." All this is in marked contrast to the method of "Cornificius," who proposed to train philosophers "suddenly." John continues: Bernard of Chartres, the most copious source of letters in Gaul in modern times, followed this method, and in the reading of authors showed what was simple, and fell under the ordinary rules; the figures of grammar, the adornments of rhetoric, the quibbles of sophistries; and where the subject of his own lesson suggested reading related to other arts, these matters he brought into full view, yet in such wise that he did not teach everything about each topic but, in proportion to the capacity of his audience, dispensed to them in due time the full scope of the subject. And because the brilliancy of any speech depends either on _Propriety_ (that is, the correct agreement of adjective or verb with the substantive) or on _Metathesis_ (that is, the transfer of the meaning of an expression for a worthy reason to another signification), these were the things which he took every opportunity to inculcate in the minds of his hearers. And since the memory is strengthened by exercise and the wits are sharpened by imitating what is heard, he urged some by warnings, and some by floggings and punishments [to the constant practice of memorizing and imitation]. They were individually required on the following day to reproduce some part of what they had heard the day before, some more, some less, for with them the following day was the pupil of the day preceding.
