My aim in this paper is to advance our understanding of medieval approaches to consciousness by focusing on a particular but, as it seems to me, representative medieval debate. The debate in question is between William Ockham and Walter Chatton over the existence of what these two thinkers refer to as “reflexive intellective intuitive cognition”. Although framed in the technical terminology of late-medieval cognitive psychology, the basic question at issue between them is this: Does the mind (or “intellect”) cognize its (...) own states via higher-order (or “reflexive”) representational states? Their debate is representative both because it highlights the central dialectical issues and alternatives at play in medieval discussions of consciousness generally and because it showcases the two main types of approach to consciousness one finds in the later medieval period, namely, those that explain consciousness in terms of intentionality (typically, higher-order intentionality), and those that understand consciousness as a non-intentional, sui-generis mode of awareness.

This book is a survey of the most important developments in Austrian philosophy in its classical period from the 1870s to the Anschluss in 1938. Thus it is intended as a contribution to the history of philosophy. But I hope that it will be seen also as a contribution to philosophy in its own right as an attempt to philosophize in the spirit of those, above all Roderick Chisholm, Rudolf Haller, Kevin Mulligan and Peter Simons, who have done so much (...) to demonstrate the continued fertility of the ideas and methods of the Austrian philosophers in our own day. For some time now, historians of philosophy have been gradually coming to terms with the idea that post-Kantian philosophy in the German-speaking world ought properly to be divided into two distinct traditions which we might refer to as the German and Austrian traditions, respectively. The main line of the first consists in a list of personages beginning with Kant, Fichte, Hegel and Schelling and ending with Heidegger, Adorno and Bloch. The main line of the second may be picked out similarly by means of a list beginning with Bolzano, Mach and Meinong, and ending with Wittgenstein, Neurath and Popper. As should be clear, it is the Austrian tradition that has contributed most to the contemporary mainstream of philosophical thinking in the Anglo-Saxon world. For while there are of course German thinkers who have made crucial contributions to the development of exact or analytic philosophy, such thinkers were outsiders when seen from the perspective of native German philosophical culture, and in fact a number of them found their philosophical home precisely in Vienna. When, in contrast, we examine the influence of the Austrian line, we encounter a whole series of familiar and unfamiliar links to the characteristic concerns of more recent philosophy of the analytic sort. As Michael Dummett points out in his Origins of Analytic Philosophy, the newly fashionable habit of referring to analytic philosophy as "Anglo-American" is in this light a "grave historical distortion". If, he says, we take into account the historical context in which analytic philosophy developed, then such philosophy "could at least as well be called "Anglo-Austrian" (1988, p. 7). Much valuable scholarly work has been done on the thinking of Husserl and Wittgenstein, Mach and the Vienna Circle. The central axis of Austrian philosophy, however, which as I hope to show in what follows is constituted by the work of Brentano and his school, is still rather poorly understood. Work on Meinong or Twardowski by contemporary philosophers still standardly rests upon simplified and often confused renderings of a few favoured theses taken out of context. Little attention is paid to original sources, and little effort is devoted to establishing what the problems were by which the Austrian philosophers in general were exercised -- in spite of the fact that many of these same problems have once more become important as a result of the contemporary burgeoning of interest on the part of philosophers in problems in the field of cognitive science.

Recent students of late medieval intellectual history have treated Oxford theologians' Sentences lectures from the 1320s to 1330s as revealing the interface of the theological, logical, and scientific thinking characteristic of a historically momentous ‘New English Theology’. Its conceptual achievement, historians generally concur, was the casting off of the speculative metaphysics of such thirteenth-century authors as Robert Grosseteste and Roger Bacon; its methodological novelty made it akin to twentieth-century analytic philosophy and seminal for the early Scientific Revolution. Yet the metaphysically (...) cast thirteenth-century sciences of perspectiva and astrologia persisted among scholars long into the early modern period. To show how this apparent paradox may be dissolved, this article details the intersection of thirteenth-century metaphysics and fourteenth-century analysis in the lectures of a controversial and influential proponent of the Oxford theology of the 1330s.

As we now know, most, if not all, philosophers in the High Middle Ages agreed that what we immediately perceive are external objects and that the immediate object of perception must not be some image present to the mind. Yet most — but not all — philosophers in the High Middle Ages also held, following Aristotle, that perception is a process wherein the percipient takes on the likeness of the external object. This likeness — called a species — is a (...) representation (of some sort) by means of which we immediately perceive external objects. But how can perception be at once direct — or immediate — and at the same time by way of representations? The usual answer here was that the species represents the external object to some percipient even though the species itself is not at all perceived: the species is that by which I perceive and not that which I perceive. John Buridan defends this traditional view — call it direct realism with representations. However, just a couple of decades before Buridan, one of the more important philosophers at Paris, Durand of St.-Pourçain, had already rejected direct realism with representation. Durand defends what I will call direct realism without representations. On his view, a species is not at all necessary during overtly direct forms of perception, neither as cause nor as representation. This paper has two parts. In the first part, I will discuss some of the more interesting arguments that Durand makes against direct realism with representations. In the second part, I will look at Buridan's defense of the view. -/- . (shrink)

Both Pierre Duhem and his successors emphasized that medieval scholastics created a science of mechanics by bringing both observation and mathematical techniques to bear on natural effects. Recent research into medieval and early modern science has suggested that Aristotle's subalternate sciences also were used in this program, although the degree to which the theory of subalternation had been modified is still not entirely clear. This paper focuses on the English tradition of subalternation between 1310 and 1350, and concludes with a (...) discussion of the theory advanced by Thomas Claxton early in the fifteenth century.

Causality plays an important role in medieval philosophical writing: even before the rediscovery of Aristotle's major works, the created universe was seen as a rational manifestation of God's action. In the later Middle Ages, the dominant genre of medieval academic writing was the commentary on an authoritative work: Aristotle's Physics and Metaphysics were frequently commented on, and both contain a great deal of material on causation. So the nature of the philosophical and theological themes which were popular in the Middle (...) Ages led to an emphasis on causality. Writers studied the interrelationship of divine grace and natural processes, the role of the will in ethics, free will and determinism: all of these problems have an important causal component.

I examine a sixteenth-century development of the anti-realist propositional semantics which is based on the notion of ‘mode’. Pardo uses this notion to offer a personal interpretation of the Buridanian criticism of complexe significabilia. He develops a middle way between the reduction of the significate of propositions to particular things and the postulation of non-standard entities which are only complexly signifiable. The key to this middle way is Pardo's understanding of the notion of ‘mode’ as connoting a relation between individual (...) things. He offers a new interpretation of the signification of syncategorematic terms, and a definition of ‘comparative’ notions, by which something is known ‘relatively’ with respect to some other thing. And a real relational correlate is postulated for these relational ways of knowing. Relations are thus used to grant a specific significate of propositions, without renouncing the strict Buridanian rejection of any extra-categorial complexe significabilia. The role of r... (shrink)

In one corner Socrates; in the other, on the mat, his cat Felix. Socrates, of course, thinks (correctly) that Felix the Cat is on the mat. But there’s the rub. For Socrates to think that Felix is on the mat, he has to be able to think about Felix, that is, he has to have some sort of cognitive grasp of an individual — and not just any individual, but Felix himself. How is that possible? What is going on when (...) we think about things? (shrink)

This paper surveys the main issues in Suárez’s theory of visual perception, which in its complexity and systematical ordering has not been explored yet. These questions, exposed in the first five questions of the seventh disputation De sensibus exterioribus in particulari of Suárez’s Commentaria una cum quaestionibus in libros Aristotelis and in the first two sections of the fifth disputation De potentiis cognoscitivis in communi, are the following: 1) the nature of light; 2) the nature of colour; 3) the formal (...) object of vision; 4) the necessity and the nature of the visual species; 5) the critique of the theory of extramission; and 6) the organ of visual power. The main emphasis is laid on the presentation of the systematical dimension of Suárez’s visual theory. (shrink)
