Later medieval theories of free choice differ fundamentally as to the importance they assign to deliberation. Some thinkers hold that the will's choices necessarily agree with the intellect's judgment, obtained by deliberation, of what is most worth choosing in a particular circumstance. They thus think that deliberation provides the object of choice. In addition, they take the control that is essential to free choice to be rooted in deliberation. Others object that deliberation cannot ground free choice since it is itself (...) not originally in our control. They think that one can choose differently from what appears most choiceworthy upon deliberation, and so they deny that the object of choice is exclusively given by deliberation. This paper considers theories of the role of deliberation in free choice held by prominent thirteenth and early fourteenth-century thinkers. It will be shown that there are significant theoretical difficulties on both sides. (shrink)

The relation-theory of mental acts proposes that a mental act is a kind of relative entity founded upon the mind and directed at the object of perception or thought. While most medieval philosophers recognized that there is something importantly relational about thought, they nevertheless rejected the view that mental acts are wholly relations. Rather, the dominant view was that a mental act is either in whole or part an Aristotelian quality added to the mind upon which such a relation to (...) the object can be founded. In this paper, I examine Durand of St.-Pourçain's defense of the relation-theory of mental acts against two objections raised against it: the first from John Duns Scotus, among others, and the second from an anonymous Thomist and Adam Wodeham. -/- .

The present dissertation concerns cognitive psychology—theories about the nature and mechanism of perception and thought—during the High Middle Ages (1250–1350). Many of the issues at the heart of philosophy of mind today—intentionality, mental representation, the active/passive nature of perception—were also the subject of intense investigation during this period. I provide an analysis of these debates with a special focus on Durand of St.-Pourçain, a contemporary of John Duns Scotus and William of Ockham. Durand was widely recognized as a leading philosopher (...) until the advent of the early modern period, yet his views have been largely neglected in the last century. The aim of my dissertation, then, is to provide a new understanding of Durand’s cognitive psychology and to establish a better picture of developments in cognitive psychology during the period. -/- Most philosophers in the High Middle Ages held, in one form or another, the thesis that most forms of cognition (thought, perception) involve the reception of the form of the object into the mind. Such forms in the mind explain what a given episode of cognition is about, its content. According to what has been called the conformality theory of content, the content of our mental states is fixed by this form in the mind. Durand rejects this thesis, and one of the primary theses that I pursue is that Durand replaces the conformality theory of content with a causal theory of content, according to which the content of our mental states is fixed by its cause. When I think about Felix and not Graycat, this is to be explained not by the fact that I have in my mind the form of Felix and not Graycat, but rather by the fact that Felix and not Graycat caused my thought. -/- This is both a controversial interpretation and, indeed, a controversial theory. It is a controversial interpretation because Durand seems to reject the thesis that objects are the causes of our mental states. In the first half of the present dissertation, I argue that Durand does not reject this thesis but he rejects another nearby thesis: that objects as causes give to us ‘forms’. On Durand’s view, an object causes a mental state even though it does not give to us a new ‘form’. In the second half of the dissertation I defend Durand’s causal theory of content against salient objections to it. (shrink)
