"In a superb introduction by Johannes Thijssen and a lengthy and wonderfully edifying study guide by Edith Sylla, close readers will have before them several research questions and projects that could occupy them for years. [...] For students of medieval natural philosophy, the edition will generate further questions and discussions and contribute to a more nuanced picture of fourteenth-century philosophy than that provided by some earlier and still often-cited studies distorted by anachronistic comparisons and by sectarian philosophical or theological agendas. Interested readers surely look forward to the completion of the edition." - André Goddu (Stonehill College), Speculum 92/4 (October 2017), pp. 1164-1166. "The edition reviewed here is a very important contribution to a better, more precise acquaintance, based on textual evidence, with one of the more philosophically lively periods of medieval thought. The various lectiones of the manuscripts and the list of works cited by Buridan, together with the opening “Guide to the Text,” render very significant and effective support to our understanding of an ancient, truly important contribution to the history of science." - Stefano Caroti (University of Parma), Isis, Volume 108, Number 1, March 2017, pp. 179-180.
