41I am preparing an English translation of both the Tractatus longior and the Tractatus brevior of Walter Burley’s De puritate artis logicae for the “Yale Library of Medieval Philosophy.” My translation is based of course on the 1955 critical edition by Philotheus Boehner, the only reasonably reliable text available. Nevertheless, in preparing my translation, I have had several occasions to question or correct readings in Boehner’s edition. In some instances the corrections are merely obvious typo…Read more

38Walter Burley and the Obligationes attributed to William of SherwoodHistory and Philosophy of Logic 4 (1-2): 9-26. 1983.The history of the mediaeval obligationes-literature has only recently begun to be studied. Two important treatises in this literature, one by Walter Burley and the other attributed to William of Sherwood, have been edited by Romuald Green in a forthcoming book. But there is considerable doubt concerning the authenticity of the text attributed to Sherwood. The correct attribution and dating of this treatise is crucial for our understanding of the history of this literature. In this paper, we arg…Read more

36The manuscript Venice, Biblioteca Nazionale Marciana, Class XI n. 12, Zanetti Latini 301 (= 1576), contains on fols. 1r–24v a seemingly unique copy of a series of fifteen logical questions, ten on obligationes and the remaining five on insolubilia.1 The series on obligationes is untitled and unattributed in the manuscript, but the questions on insolubilia begin (fol. 18r11) “Incipiunt quaestiones super insolubilibus,” and are attributed at the end to a certain John of Wesel (fol. 24v41): “Ergo e…Read more

32In the summer of 1980, I was privileged to be on the teaching staff of the Summer Institute on Medieval Philosophy held at Cornell University under the direction of Norman Kretzmann and the auspices of the Council for Philosophical Studies and the National Endowment for the Humanities. While I was giving a series of lectures on supposition theory, I went to my office one morning, and there under the door some anonymous wag from the Institute had slid the pen and ink drawing you see in the graphi…Read more

26Three theories of obligationes: Burley, Kilvington and Swyneshed on Counterfactual ReasoningHistory and Philosophy of Logic 3 (1): 1-32. 1982.This paper defends the thesis that the mediaeval genre of logical treatises De obligatiombus contained a theoretical account of counterfacutal reasoning, perhaps the first such account in the history of philosophy. This interpretation helps to explain some of the theoretical disputes in the obligationes literature in the first half of the fourteenth century. Section 1 is introductory. Section 2 presents Walter Burley's theory, while section 3 argues for the counterfactual interpretation of oblig…Read more

23How to Start and StopJournal of Philosophical Research 19 193-221. 1994.Mediaeval logicians often wrote about changes between contradictory states, for example a switch’s changing from being on to not being on. One of the questions discussed in these writings was whether at the moment the change occurs the changing thing is in the earlier or the later state. The present paper investigates the general setting for that question, and discusses the answer given by Walter Burley, an important early-fourteenth century author whose theory was a standard one. Burley’s theor…Read more

20(1) Assuming the significates of non-complex terms, in this treatise I intend to investigate certain properties of terms, [properties] that are applicable to them only insofar as they are parts of propositions. (2) Now I divide this tract into three parts. The first is about the supposition of terms, the second about appellation, and the third about copulation. Supposition belongs to the subject, appellation to the predicate. Copula-.
