65seem to be a kind of corruption of the elements and not a mixture. Again, if the substantial form of a mixed body is the act of matter without presupposing the forms of simple bodies, then the simple bodies of the elements will lose their definition (rationem). For an element is that of which something is primarily composed, and exists in it and is indivisible ac-.

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

151Apart from his Consolation of Philosophy, perhaps the most well known text of Boethius is his discussion of universals in the Second Commentary on Porphyry’s Isagoge.1 In that passage, he first reviews the arguments for and against the existence of universal entities, and then offers a theory he attributes to Alexander of Aphrodisias, a kind of theory called in recent times “moderate realism,” according to which there are no universal entities in the ontology of the world, but nevertheless there…Read more

73The problem of universals and wyclif's alleged "ultrarealism"Vivarium 43 (1): 111-123. 2005.John Wyclif has been described as "ultrarealist" in his theory of universals. This paper attempts a preliminary assessment of that judgment and argues that, pending further study, we have no reason to accept it. It is certainly true that Wyclif is extremely vocal and insistent about his realism, but it is not obvious that the actual content of his view is especially extreme. The paper distinguishes two common medieval notions of a universal, the Aristotelian/Porphyrian one in terms of predicatio…Read more

48The Cambridge Companion to Ockham (edited book)Cambridge University Press. 1999.The Franciscan William of Ockham was an English medieval philosopher, theologian, and political theorist. Along with Thomas Aquinas and Duns Scotus, he is regarded as one of the three main figures in medieval philosophy after around 1150. Ockham is important not only in the history of philosophy and theology, but also in the development of early modern science and of modern notions of property rights and church-state relations. This volume offers a full discussion of all significant aspects of O…Read more

45How 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
