Parisian Obligations ILLC Latin Reading Group Abstract: This is a work-in-progress translation of and commentary on the anonymous text Obligationes Parisiensis edited in [dR75]. The translation and commentary are the result of one of the Latin reading groups at the Institute for Logic, Language and Computation at the Universiteit van Amsterdam, running Fall 2006 - Spring 2007. The group was headed by Sara L. Uckelman, and consisted variously of Miguel AntonioMatamala, Jaap Maat, Katherina Rybalko, and Andreas Witzel. De Rijk in his introduction to his edition notes that the organization of the Parisiensis text, into positio, depositio, and dubitatio, is similar to the division found in a tract on obligations ascribed by Romuald Green to William of Sherwood. Despite this similarity, de Rijk says that 'a comparison of our treatise with William's seems not to point to any relationship between them' ([dR75], p. 25). Nevertheless, he uses the Sherwood tract as a date ante quem for the Parisiensis tract, and concludes that the latter text must date from the early 13th century. Green is tentative in his ascription of the text he edited to Sherwood. These objections were dismissed by de Rijk, who believed that the tract belonged to Sherwood without a doubt. However, Stump says that 'there are other serious worries about the attribution of this treatise to Sherwood. . . Careful consideration of these worries. . . make it seem altogether possible that what we really have in the putative Sherwood treatise is an early treatise on obligations byWalter Burley' ([St82], pp. 316-317). Braakhuis in [Br98] agrees with Stump, and says that the treatise should not be dated before the end of the 13th century. If this is the case, then the dating of the Parisiensis text may need to be revisited. We do not address any of the questions raised above. However, we translate the section on dubitatio in the Pseudo-Sherwood text in ยง3, in order to compare it with that found the Parisiensis text. Keywords: obligationes; dubitatio
