Previously Unpublished Works, Fascicle 15

cussion on infinite and privative predicates logical terms referring to words with negative prefixes like "non-man" or terms denoting a lack, such as "blind" on page 284 and the examples here and on page 285 occur on page 57 of the Compendium, and the general conclusion on page 283, lines 5 to 19, is the same as that on page 59 in the second to last sentence of the chapter.

The views of Richard of Cornwall, also known as Richard the Red original: "Richardus Rufus", are found in his Commentary on the Sentences a standard medieval theological textbook by Peter Lombard (Balliol Manuscript 62). These were identified and discussed by F. Pelster, S.J. in the journal Scholasticism original: "Scholastik", volume 4, page 410. Other works have since been identified. See also Little, The Franciscan School at Oxford in the Franciscan Historical Archive original: "Arch. Franc. Hist.", volume 19, page 841.

As the end of my self-imposed task draws near, I wish to take this opportunity of offering my most humble and hearty thanks to all those whose help has made the publication of this series of "Previously Unpublished Works of Roger Bacon" possible. In the first place, I thank my Oxford friends, chief among them Sir William Osler and Dr. and Mrs. Charles Singer. I owe the support of my enterprise for many years to their energy and devotion. I also thank the Delegates of the Clarendon Press for undertaking the printing. In the next place, I thank the British Academy and the Pilgrim Trust for generous annual grants in aid of printing and publication. Medieval students will now have in their hands substantially everything known to be written by Roger Bacon. I trust this will justify their generosity, even if some hopes of possible new finds are disappointed. More and more in recent years, I have wondered whether the title of Wonderful Teacher original: "Doctor mirabilis"; a traditional title given to Bacon by later scholars to honor his vast knowledge may have been earned by the controversialist and the scholastic logician which Bacon was, before his interest in mathematics and experimental natural philosophy was aroused to make him one of the great fore-runners of modern science.

As regards the present volume, my most grateful thanks are due in the first place to the readers of the Press. I would gladly have put their names on the title-page as collaborators but for the strict rule of anonymity. I also thank Dr. Clement C. J. Webb and Dr. Dorothea Sharp, who confirmed my impression that Bacon was referring to Richard of Cornwall in his criticism of the nature of predication the act of asserting a property or characteristic about a subject in logic. Finally, I thank Dr. Little who for over thirty years has been a constant help in every way as friend and adviser,
