Boethii Daci Aliorumque Sophismata by Boethius of Dacia (review)

Reviewed by: Boethii Daci Aliorumque Sophismata by Boethius of Dacia Julie Brumberg-Chaumont Boethius of Dacia. Boethii Daci Aliorumque Sophismata. Edited by Sten Ebbesen and Irène Rosier-Catach. Corpus Philosophorum Danicorum Medii Aevi, 9. Odense: University Press of Southern Denmark, 2021. Pp. 624. Hardback, 400.00 DKK. This volume offers a reliable and accurate scholarly edition of two collections of thirteenthcentury sophismata (logical and grammatical puzzles) contained in ms. Brugge, Stedelijke Openbare Bibliotheek 509 (=B) and ms. Firenze, Biblioteca Medicea-Laurenziana 12 sin. 3 (=F). Taken together, these two collections constitute a set of twenty-three sophismata called "Sophismata Florentino-Brugensia" in the catalogue published by Sten Ebbesen and Frédéric Goubier (A Catalogue of Thirteenth-Century Sophismata [Paris: Vrin, 2010]). These sophismata were previously available only in partial editions. Specifically, the two versions of the sophisma "Omnis homo de necessitate est animal," previously both ascribed to Boethius of Dacia, were partially edited from F by Grabmann in 1940 and from B by Roos in 1962. Other sophismata in this collection have been previously edited by Ebbesen, but their editions should now be considered "obsolete," according to the editor himself (9). Each sophisma is identified by an S followed by a number (S1, S2, etc.). In turn, each sophisma deals with several issues or problems, each one of which is identified by a P followed by a number (P1, P2, etc.). The volume is very usefully completed by an index of explicit and implicit references to other works and an index of parallel passages, both compiled by Kristian Thomsen Purreskov (591–601). Finally, this edition is accompanied by a selective but still rich index of words, where special attention has been dedicated to the sophismata by Boethius of Dacia (603–24). All the material is presented in a clear and accurate way. There are only a few minor material errors (specifically, the running titles for problems in S4 are messy; at 33, "a*" should be read as "b*"; at 49, "S14" should be read as "S18"). Sten Ebbesen is the sole editor of all sophismata except for the three that deal with grammatical subjects, for which Irène Rosier-Catach is the main editor, with Ebbesen serving as a coeditor. Concerning the authorship of each sophisma, Ebbesen follows the indications contained in F, but he also provides some independent discussions (24–26). Thus, he ascribes two sophismata to Boethius of Dacia, ten to Peter of Auvergne, one to an otherwise unknown Nicholas of Normandy, and the remaining ten to anonymous masters. They are listed in detail in the "Index sophismatum et problematum" (65–69). After a summary of the contents of the volume, Ebbesen's introduction contains five sections of different lengths: first, a history of the edition (7–9); second, a general description of the structure and functioning of sophismata (9–13); third, a description of the seven manuscripts used for the edition (14–22); fourth, a discussion about authorship (22–58); and fifth, an explanation of the principles of the edition (58–62). In the third section, Ebbesen provides a wealth of information about manuscripts, stemma codicum, and evaluations of variants, especially about the relationship between S and B for the sophismata contained in both manuscripts. In this regard, Ebbesen establishes that B and F are probably not two independent reportationes of the same oral disputation, that they had a common ancestor, and that they do not depend on one another (25–32). The fourth section, about authorship, demonstrates that the collection contained in F is earlier than that contained in B. One major result is that the text copied in B (S1B) ("Omnis homo de necessitate est animal") is not by Boethius of Dacia (35). Because of F priority, that manuscript is chosen as the main witness for those sophismata or parts of sophismata that are common to F and B. The second section makes an extremely significant historical and doctrinal contribution to the history of logic, particularly the history of logical practices and their textual records.
