XII Why we have caused books of grammar to be so diligently prepared XIII Why we have not wholly neglected the fables of the poets XIV Who ought to be special lovers of books XV Of the advantages of the love of books XVI That it is meritorious to write new books and to renew the old XVII Of showing due propriety in the custody of books XVIII Showeth that we have collected so great store of books for the common benefit of scholars and not only for our own pleasure XIX Of the manner of lending all our books to students XX An exhortation to scholars to requite us by pious prayers PROLOGUE To all the faithful of Christ to whom the tenor of these presents may come, Richard de Bury, by the divine mercy Bishop of Durham, wisheth everlasting salvation in the Lord and to present continually a pious memorial of himself before God, alike in his lifetime and after his death. What shall I render unto the Lord for all His benefits towards me? asks the most devout Psalmist, an invincible King and first among the prophets; in which most grateful question he approves himself a willing thank-offerer, a multifarious debtor, and one who wishes for a holier counsellor than himself: agreeing with Aristotle, the chief of philosophers, who shows (in the 3rd and 6th books of his Ethics) that all action depends upon counsel. And indeed if so wonderful a prophet, having a fore-knowledge of divine secrets, wished so anxiously to consider how he might gratefully repay the blessings graciously bestowed, what can we fitly do, who are but rude thanksgivers and most greedy receivers, laden with infinite divine benefits? Assuredly we ought with anxious deliberation and abundant consideration, having first invoked the Sevenfold Spirit, that it may burn in our musings as an illuminating fire, fervently to prepare a way without hinderance, that the bestower of all things may be cheerfully worshipped in return for the gifts that He has bestowed, that our neighbour may be relieved of his burden, and that the guilt contracted by sinners every day may be redeemed by the atonement of almsgiving.
