Ockham holds what nowadays would be characterized as a “higher-order perception” theory of consciousness. Among the most common objections to such a theory is the charge that it gives rise to an infinite regress in higher-order states. In this paper, I examine Ockham’s various responses to the regress problem, focusing in particular on his attempts to restrict the scope of consciousness so as to avoid it. In his earlier writings, Ockham holds that we are conscious only of (...) those states to which we explicitly attend. This view, I go on to argue, is inadequate on both phenomenological and philosophical grounds. Interestingly, and perhaps for this very reason, in later works, Ockham goes on to develop an alternative explanation for his account of the limited scope of consciousness. (shrink)

This article focuses on one aspect of the late mediaeval debate over divine power, as it was discussed by Oxford philosophers Walter Chatton (d. 1343) and William Ockham (d. 1347). Chatton and Ockham would have agreed, for example, that God is ultimately responsible for the existence of the works of Pablo Picasso, but they would not agree over wheher it violates God's omnipotence to say that he cannot make something that Picasso made, for example, the painting Guernica, (...) without using Picasso himself as an intermediate cause. The context of their dispute was a larger debate regarding the ontological status of relations. This article (1) explains how these two issues, omnipotence and relations, became so interestingly tangled together, (2) tries to see which of the two men mentioned above got the better of their exchange, and finally (3) draws out some important consequences for fourteenth-century discussions of causality, occasionalism, and omnipotence.

William Ockham held that, in addition to written and spoken language, there exists a mental language, a structured representational system common to all thinking beings. Here I present and evaluate an argument found in several places across Ockham's corpus, wherein he argues that positing a mental language is necessary for the nominalist to meet certain ontological constraints imposed by Aristotle’s account of scientific demonstration.

There is a long history of philosophers granting a privileged epistemic status to cognition of directly present objects. In this paper, I examine three important historic accounts which provide different models of this cognitive state and its connection with its objects: that of the Stoics, who are corporealists and think that ordinary perception may have an epistemically privileged status, but who seem to struggle to accommodate non-perceptual cognizance; that of Augustine, who thinks that incorporeal objects are directly present to us (...) in ‘intellectual perception’, and that, by way of contrast, ordinary sense-perception does not have a privileged epistemic status; and that of William of Ockham, who allows for unmediated action at a distance and is fairly generous about what counts as being directly present.

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham (...) responds to this dilemma, his razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

This paper explores William Ockham's account of memory with a view to understanding its implications for his account of the nature and persistence of human beings. I show that Ockham holds a view according to which memory (i) is a type of self-knowledge and (ii) entails the existence of an enduring psychological subject. This is significant when taken in conjunction with his account of the afterlife. For, Ockham holds that during the interim state—namely, after bodily death, (...) but prior to bodily resurrection—we retain and recall our embodied experiences. This entails that the subject of our embodied psychological states can survive in a disembodied state and continue to engage in characteristic rational activities—a claim that appears to run against Ockham's own commitment to a hylomorphic conception of human beings (as essentially material). A central aim of this paper is to explore the prospects for reconciling Ockham's account of interim memory with his account of human beings. (shrink)

In this paper I examine William Ockham’s theory of judgment and, in particular, his account of the nature and ontological status of its objects. Commentators, both past and present, habitually interpret Ockham as defending a kind of anti-realism about objects of judgment. My aim in this paper is two-fold. The first is to show that the traditional interpretation rests on a failure to appreciate the ways in which Ockham’s theory of judgment changes over the course of (...) his career. The second, and larger, aim is to show that careful attention to these changes in Ockham’s account (and to the motivations for them) sheds new light on broader developments in his philosophy of mind—specifically, on his views about the nature of concepts and on his account of the nature and structure of intentionality itself. (shrink)

Among medieval Aristotelians, William of Ockham defends a minimalist account of artifacts, assigning to statues and houses and beds a unity that is merely spatial or locational rather than metaphysical. Thus, in contrast to his predecessors, Thomas Aquinas and Duns Scotus, he denies that artifacts become such by means of an advening ‘artificial form’ or ‘form of the whole’ or any change that might tempt us to say that we are dealing with a new thing (res). Rather, he (...) understands artifacts as per accidens composites of parts that differ, but not so much that only divine power could unite them, as in the matter and form of a proper substance. For Ockham, artifacts are essentially rearrangements, via human agency, of already existing things, like the clay shaped by a sculptor into a statue or the stick and bristles and string one might fashion into a broom. Ockham does not think that a new thing is thereby created, although his emphasis on the contribution of human artisans seems to leave questions about the ontological status of their agency open. In any case, there are no such things as natural statues, any more than substances created by human artifice. (shrink)

This paper attempts to demonstrate that the logical problematic of signification, has a very dangerous socio-political effect due to the ontological implication that is connected to the signification of terms in logic. It expounds the notion of signification in Formal Logic as exposed by William of Ockham. It thus, employs this notion of signification of terms, to discuss the term “Fulani”, to show the danger potent in distorting the signification of the term “Fulani” as in every conventional and (...) connotative terms. This work claims that as a result of the connection between logic and ontology, conceptualization and perception, names and reality, the distortion of terms, which are the building blocks of propositions in logic could lead to a dangerous cognition and perception of ontological realities. To this end, it posits a critique on the dangerous change in the signification of the term “Fulani”, in the conceptualization and perception of present day Nigeria people, of West Africa. A dangerous change, as this paper claims, if not speedily reconstructed and re-conceptualized, could lead to a disastrous situation in the socio-political reality of the Nigerian State. (shrink)

William of Ockham seems to have endorsed the view (i) that a whole is its parts, (ii) that some things are such that whether they together compose a whole is contingent, and (iii) that parts are ontologically prior to the whole they compose. Ockhamist Composition as Identity is the conjunction of these three claims. It seems doubly absurd since Leibniz’s Law arguments can be run against both the conjunction of (i) and (ii) and that of (i) and (iii). (...) In this article, I appeal to recent developments in counterpart theory to block these arguments and adequately interpret the Ockhamist version of the view that composition is identity. (shrink)

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.

Truth is a key notion in Ockham’s philosophical reductionist program, a notion that has been the object of contrasting interpretations in scholarship. My interpretation is that, for Ockham, ‘being true’ expresses an epistemological relation, namely the one through which our mind reflects on a proposition of language, compares it with an extra-mental state of affairs, and thus ascertains their correspondence. Placing truth at a point of intersection of language with mind and reality, Ockham’s interpretation of Aristotle’s characterization (...) of philosophy as the science of truth comes to be innovative. For Ockham, philosophy is a meticulous training of interpretation of language in order to account correctly for the truth-value of propositions. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it (...) is contradictory for God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

Aristotle and William of Ockham both argue that existence or being is a predicate, though not a distinguishing predicate. I place Ockham’s argument in an Aristotelian context and discuss its merits. I then turn to empiricist criticisms of the view that we can coherently predicate being of things. I argue that while Ockham’s argument is cogent, his account of how we come to have the concept of being is inadequate. Ockham’s view needs to be supplemented (...) with Kantian insights. (shrink)

This paper reconsiders Ockham's critique of the species theory of cognition. As Ockham understands this theory, it says that the direct objects of cognition are mental representations, or species. According to many commentators, one of Ockham's main objections to this theory was that, if the direct objects of cognition are species rather than external objects, we will never be able to establish whether or not a given species is a veridical representation of the world. In this paper (...) I argue that this line of interpretation sits uneasily with Ockham's epistemology, and offer a new interpretation of Ockham's critique of species. (shrink)

This book discusses fundamental topics on contemporary Ockhamism. The collected essays show how contemporary Ockhamism can impact areas of research such as semantics, metaphysics and also the philosophy of science. In addition, the volume hosts one historian of Medieval philosophy who investigates the way in which William of Ockham “in flesh and bone” construed time and, more generally, future contingency. The essays explore the different meanings of this theory. They cover three main topics, in particular. The first examines (...) the thesis that sentences and propositions about the future have a definite truth value, without any ensuing commitment to determinism or fatalism. The second topic looks at the problem whether the branching-time model needs to countenance a privileged branch (the so-called Thin Red Line). Finally, the third topic considers the idea that there are so-called soft facts. These would be the subject matter of sentences and propositions verbally about the present or the past, but metaphysically about a later time, and which might change in the future. Overall, the book provides an updated and rigorous idea of the debate about Ockhamism. It gives readers a deeper understanding into this philosophical approach influenced by William of Ockham, characterized by the rejection of the Aristotelian idea that, in order to preserve the contingency of the future, future contingents must be deemed neither true nor false.

The quodlibetal collection sat Oxford in the are fourteenth century are discussed.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to OckhamJeffrey E. BrowerPaul Vincent Spade, editor. The Cambridge Companion to Ockham. Cambridge: Cambridge University Press, 1999. Pp. xii + 400. Cloth, $54.95.Contemporary analytic philosophers have always been among the most enthusiastic audiences for the volumes in the Cambridge Companion series. And of all the great philosophers of the Middle Ages, perhaps none has appealed more to their sensibilities than William Ockham. (...) It is fitting, therefore, that after the publication of the Companion to Aquinas—the first volume in the series devoted to a medieval philosopher—there should appear a Companion to Ockham.The fifteen chapters comprising this volume survey the entire range of Ockham's thought and may conveniently be divided into four main parts. The first part (chaps. 2-7) deals with Ockham's most enduring legacy: his contribution to issues falling within the domain of logic, philosophy of language, and metaphysics. The second part (chaps. 8-9) is devoted to issues in epistemology and philosophy of mind/cognition. The third part (chaps. 10-13) focuses on Ockham's views in ethics, action theory, and political philosophy. And the fourth part (chaps. 14-15) considers aspects of his philosophical theology. In addition, there is also an historical chapter (chap. 1), placing Ockham's life and works in their late-medieval intellectual context, and a brief editor's introduction, including a very useful list of all Ockham's writings, together with the best (sometimes, the only) Latin editions and English translations available.The volume is well organized and beautifully conceived. Some chapters are quite difficult, and in places contain material that is likely to be unfamiliar even to specialists in medieval philosophy. But the way in which they have been organized maximizes their usefulness and accessibility to specialists and non-specialists alike. The earlier parts of the volume lay the foundation for later ones, and the individual chapters within each part are arranged so as to build on and complement one another. This is perhaps most evident in the five chapters comprising the first part. Calvin Normore's presentation ofOckham's logic (in chap. 2) nicely prepares the reader for Claude Panaccio's discussion (in chap. 3) of Ockham's theory of mental language. Panaccio's chapter, in turn, provides the framework for David Chalmer's analysis (in chap. 4) of the debate over whether [End Page 588] Ockham's mental language permits synonymous expressions. Again, these three chapters taken together provide important background for Paul Spade's treatment (in chap. 5) of Ockham's views in metaphysics, which are closely related to his logic and philosophy of language. Finally, Gyula Klima's discussion (in chap. 6) ofhow Ockham's views in semantics and ontology differ from those of his predecessors, and André Goddu's discussion (in chap. 7) of Ockham's philosophy of nature, can be fully appreciated only against the background of the preceding chapters.What is perhaps most impressive about the volume, however, is the extent to which it succeeds at providing a systematic introduction to Ockham's philosophical achievement. All the chapters are, to some extent, concerned with matters of textual analysis and interpretation. But most of them involve much more than a mere survey of Ockham's texts. For example, in each of the four main parts, there is at least one chapter that attempts to locate Ockham's views in relation to those of his predecessors or contemporaries (such as Aquinas and Scotus), with the result that we get a sense of Ockham's place in the major medieval debates to which he contributed. At the same time, the volume introduces us to some of the most lively current debates in Ockham scholarship. It does this, not merely by summarizing them, but by actually carrying them out over the course of its chapters. For example, Eleonore Stump provides a sophisticated defense (in chap. 8) of what has become a standard interpretation of Ockham's theory of intuitive and abstractive cognition. In the following chapter, however, Elizabeth Karger rejects the standard interpretation on the basis of a re-reading of certain key texts. Again, in the first part of the volume there is a running debate... (shrink)

Among the most widely discussed of William of Ockham’s texts on ethics is his Quodlibet III, q. 14. But despite a large literature on this question, there is no consensus on what Ockham’s answer is to the central question raised in it, specifically, what obligations one would have if one were to receive a divine command to not love God. (Surprisingly, there is also little explicit recognition in the literature of this lack of consensus.) Via a close (...) reading of the text, I argue, contrary to much of the literature, that Ockham believes that if one were given this command, one would be obligated to refrain from loving God and would also be able to fulfill this obligation without any moral wrongdoing. Among other results, this study will help clarify Ockham’s much-discussed claim that loving God is “a necessarily virtuous act.”. (shrink)

This article analyzes the significance of the concepts “sovereignty” and “popular sovereignty” regarding the construction of modern law. Modern law isdefined in this study as a language of subjective rights (claim, liberty, power and immunity) and therefore has a nomological and authoritative character. The shift from low Middle-age to the beginning of Modernity seems to be the decisive period to understand the construction of modern law, due to the reception of Aristotle’s political writings and Roman law, aside from the rejection (...) of strong or thomist realism. In this sense, three works are analyzed: Marsilio of Padua “DefensorPacis”, William of Ockham “Breviloquium de Principatur Tyrannico” and Jean Bodin “Six Books of the Commonwealth”. The results seem to address that popular sovereignty as a foundation for legal language is in direct opposition to the acceptance of the strong concept of sovereignty, as stated by Bodin. (shrink)

Rondo Keele makes a foray into what he calls 'applied logic', investigating a complex argument strategy employed against Ockham by his greatest contemporary opponent, Walter Chatton. Chatton conceives a two-part strategy which attempts to force a kind of iteration of conceptual analysis, together with an infinite explanatory regress, in order to establish that one particular philosophical analysis is ultimately dependent on another. Chatton uses this strategy against Ockham in order to show that the latter's reductionist metaphysics depends ultimately (...) upon a deeper level of realist assumptions that he can neither evade nor explain away. Keele then shows how, earlier in his career, Chatton found himself on the receiving end of this same strategy, defending his own highly original solution to the problem of future contingents from the very iteration-regress attack he would subsequently use on Ockham. Keele concludes with an examination of Chatton's attempts to avoid the consequences of his own strategy, and draws some connections between this argument strategy and modal collapse in modern logics.

This paper is the written version of my contribution to the International Conference «30 years Logica modernorum» held in Amsterdam in November 1997 in honor of the late prof. Lambertus M. de Rijk. Research on Oresme’s modi rerum theory was in the first stage, while now we can read the critical edition of Oresme’s Physics commentary, where modi are introduced and widely used. In this paper I shall consider Oresme’s polemical use of modi rerum, trying to set it in the (...) larger context of both his ontology and his epistemology. Oresme’s challenge to either a realist or terminist ontology by means of modi rerum conceals probably an attack to William of Ockham; Oresme refers explicitly to Ockham concerning exclusive propositions, but I think that on many other occasions the polemical target of Oresme’s criticism can be reasonably identified in William of Ockham or in some unnamed followers of the Venerabilis Inceptor. Some hints are reserved also to the possible sources of Oresme’s modi rerum. (shrink)

This paper traces a rather peculiar debate between William Ockham, Walter Chatton, and Robert Holcot over whether it is possible for God to know more than he knows. Although the debate specifically addresses a theological question about divine knowledge, the central issue at stake in it is a purely philosophical question about the nature and ontological status of propositions. The theories of propositions that emerge from the discussion appear deeply puzzling, however. My aim in this paper is to (...) show that there is a way of making sense of these views (and, by implication, of much of what is puzzling about medieval theories of propositions). The key, I argue, lies in getting clear about the precise theoretical roles these thinkers assign to propositions in their accounts of propositional attitudes. (shrink)

The paper presents Suárez’s view on the individuation of beings, which he developed in his Disputatio V, De unitate individuali eiusque principio. The aim, apart from simply presenting Doctor Eximius’s thought, is also to compare his views with his scholastic predecessors. When considering the question of individuation, Suárez remained under a considerable influence of the medieval tradition, which, however, he transformed in his writings according to his own convictions. He used the language of Duns Scotus when speaking of individuation and (...) determining it in terms of indivisibility, but rejected the idea of individuation by matter, classically attributed to the Thomistic School. Postulating the individuation principle, identified with the entity, and not with the act of existence nor the being of haecceitas, Suárez departed from non-classical interpretations of the thought of Thomas Aquinas as well as from the Scotistic solutions, and postulated a view that to some extent resembled that of Ockham and Bonaventure, although Suárez does not explicitly refer to the latter.

During the 13th century, several logicians in the Latin medieval tradition showed a special interest in the nature of impossibility, and in the different kinds or ‘degrees’ of impossibility that could be distinguished. This discussion resulted in an analysis of the modal concept with a fineness of grain unprecedented in earlier modal accounts. Of the several divisions of the term ‘impossible’ that were offered, one became particularly relevant in connection with the debate on ars obligatoria and positio impossibilis: the distinction (...) between ‘intelligible’ and ‘unintelligible’ impossibilities. In this article, I consider some 13th-century tracts on obligations that provide an account of the relation between impossibility and intelligibility and discuss the inferential principles that are permissible when we reason from an impossible – but intelligible – premise. I also explore the way in which the 13th-century reflection on this topic survives, in a revised form, in some early 14th-century accounts of positio, namely, those of William of Ockham, Roger Swineshead and Thomas Bradwardine.

In this article, we discuss the notion of merely confused supposition as it arose in the medieval theory of suppositio personalis. The context of our analysis is our formalization of William of Ockham's theory of supposition sketched in Mind 86 (1977), 109-13. The present paper is, however, self-contained, although we assume a basic acquaintance with supposition theory. The detailed aims of the paper are: to look at the tasks that supposition theory took on itself and to use our (...) formalization to relate them to more modern ideas; to explain the notion of merely confused supposition and to defend it against certain criticisms; and to discuss two issues closely related to the idea of merely confused supposition which we could not broach in a shorter article: the mode of supposition of terms in intensional contexts, and the possible existence of a fourth mode, often called suppositio copulatim.

An overview of debates in ethical theory within Christian Scholasticism in the decades after Thomas Aquinas.

The methods of intellectual history have not yet been applied to studying the invention of technology for printing texts and images ca. 1375–ca. 1450. One of the several conceptual developments in this period refl ecting the possibility of mechanical replication is a view of the relationship of eternity to durational time based on Gregory of Nyssa’s philosophy of time and William of Ockham’s. Th e article considers how changes in these ideas helped enable the conceptual possibilities of the (...) dissemination of ideas. It describes a direct connection of human perceptual knowledge to divine knowledge that enhanced the authority of printed production to transfer and reproduce the true and the good. (shrink)

The focus of the article is the self-predication principle, according to which the/a such-and-such is such-and-such. We consider contemporary approaches (Frege, Russell, Meinong) to the self-predication principle, as well as fourteenth-century approaches (Burley, Ockham, Buridan). In crucial ways, the Ockham-Buridan view prefigures Russell’s view, and Burley’s view shows a striking resemblance to Meinong’s view. In short the Russell-Ockham-Buridan view holds: no existence, no truth. The Burley-Meinong view holds, in short: intelligibility suffices for truth. Both views approach self-predication (...) in a uniform way. We were unable to find a medieval philosopher who, like Frege, approaches self-predication in a non-uniform way. We do not want to dispute that there are also considerable differences between the contemporary and the fourteenth-century approach to self-predication. Importantly, fourteenth-century accounts of self-predication rely strongly on the identity theory of predication, and this theory is not endorsed by contemporary philosophers of language. Nevertheless, some basic tenets seem to us to be clearly shared between fourteenth-century and contemporary thinkers. (shrink)

CATEGORY: Philosophy play; historical fiction; comedy; social criticism. -/- STORYLINE: Tim, a physics professor with a certain taste for young female university students, recently got a new appointment at a London university. But, as it turns out, he is still unsatisfied. Why? Is it because Rachael unexpectedly left him under strange circumstances? Or does it have to do with his sudden departure from another university? Or is it his research? When Tim meets Christianus for a brown-bag discussion on philosophy and (...) science, new facts and perspectives are revealed. -/- TOPICS: In the course of the play, Tim and Christianus discuss different metaphysical, epistemological, and ontological ideas. Many of these are either related to isssues in the philosophy of science (explanation, methodology, scientific investigation, etc.), or to issues in human psychology and the philosophy of mind (the self vs. the mind, dualism, ‘Who am I?’, etc.). In one scene, for example, Tim tries to invoke ‘Ockham’s Razor’ (or ‘Occam’s Razor’) to quickly dismiss some of Christianus’s metaphysical ideas (see Scene VII: Ockham’s Raisin; Scene XIII: The Raisin Tale Revisited); in another scene, Christianus introduces his ‘Postman’ scenario, and the idea that successful (‘scientific’) prediction or forecasting is not necessarily a sure sign of true understanding (see Scene XV: The Postman Always Turns Twice). -/- NOTES: This work features elaborate footnotes and comments (including full bibliographical references) by the author, to enhance the reader's experience of the play and its philosophizing characters.

Medieval authors generally agreed that we have the freedom to choose among alternative possibilities. But most medieval authors also thought that there are situations in which one cannot do otherwise, not even will otherwise. They also thought when willing necessarily, the will remains free. The questions, then, are what grounds the necessity or contingency of the will’s acts, and – since freedom is not defined by the ability to choose – what belongs to the essential character of freedom, the ratio (...) libertatis. This article studies medieval theories of freedom without choice from William of Auxerre to William of Ockham and their background in Augustine, Anselm of Canterbury, and Bernard of Clairvaux.

The important impact of the French Franciscan Peter Auriol (ca. 1280-1322) upon contemporary philosophical theology at Oxford is well known and has been well documented and analyzed, at least for a narrow range of issues, particularly in epistemology. This article attempts a more systematic treatment of his effects upon Oxford debates across a broader range of subjects and over a more expansive duration of time than has been done previously. Topics discussed include grace and merit, future contingents and divine foreknowledge, (...) and the logic of the Trinity. (shrink)

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)

According to standard late medieval Christian thought, humans in heaven are unable to sin, having been “confirmed” in their goodness; and, nevertheless, are more free than humans are in the present life. The rise of voluntarist conceptions of the will in the late thirteenth century made it increasingly difficult to hold onto both claims. Peter Olivi suggested that the impeccability of the blessed was dependent upon a special activity of God upon their wills and argued that this external constraint upon (...) their wills did not eliminate their freedom. Later voluntarists largely agreed with Olivi in attributing the confirmation of the blessed to be dependent upon God’s activity in some way, but disputed the means by which and the extent to which the wills of those in heaven could be said to retain their freedom. This paper will examine various attempts made to either harmonize these two claims or else to soften the blow of rejecting one of them; among the authors surveyed will be Peter John Olivi, John Duns Scotus, Henry of Harclay, William of Ockham, Walter Chatton, and Margurite Porete.

È possibile ammettere, pensare e addirittura verificare che una cosa che sia accaduta nel passato possa non essere più accaduta in un momento presente? Ad esempio, si può, oggi, fare in modo che Roma non sia mai stata fondata? Come è possibile mutare la regolare causalità degli accadimenti di quel passato – il nostro e quello degli uomini che ci hanno preceduti – che sembra essere fondato sui vincoli di una strettissima necessità? E che dire quando questo sconvolgimento dell’ordine del (...) mondo arriva a toccare anche le possibilità logiche o le scelte di un “Divin Fattore”? D’altro canto, se ribaltiamo il discorso e ci volgiamo al futuro, sapere che qualcuno conosce in anticipo che ogni cosa avverrà o non avverrà, e come e quando, non limita forse la nostra libertà? Quale strada scegliere, allora? Abbandonare il principio di contraddizione, su cui è fondata la nostra logica, oppure lasciar cadere il predicato dell’onnipotenza e dell’onniscienza, che garantiscono a Dio di affacciarsi sulla scena del mondo contingente – quello che noi, qui e ora, vediamo e tocchiamo prima ancora di rappresentarcelo in modo astratto – cambiandolo a suo piacimento? O dovremo abbandonare il principio di un agente divino capace di sapere ogni cosa in anticipo, perché fuori dal tempo e tale da poter cambiare l’ordine nel quale siamo stati gettati? Dovremo forse limitarne la potenza a quella di un orologiaio sottomesso alle leggi che egli stesso ha creato per regolare il mondo? Oppure rinunciare alla capacità di agire diversamente da come si agisca, di dialogare con chi agisce secondo schemi e modelli di credenza radicalmente, o parzialmente diversi dai nostri, o anche solo di pensarlo e di immaginarlo possibile? Insomma, ci sono più cose in cielo e in terra o nella filosofia? Le domande si succedono l’una all’altra come le teste dell’Idra di Lerna, che ricrescevano dalla radice una volta tagliate*. Per usare un celebre modo di dire, molto usato nella filosofia italiana del secolo scorso, sembra quasi che si voglia in questo modo “mettere le brache al mondo”. La costellazione di temi e questioni che si viene così definendo è espressa filosoficamente con il termine “compatibilismo teologico” e riguarda in generale la possibilità che siano conciliabili, in modo tale che l’esistenza dell’uno non implichi la necessaria negazione dell’altro, la necessità dell’ordine del mondo, e con esso l’onnipotenza e la prescienza proprie di un soggetto divino come quello delle grandi religioni monoteiste, da una parte, e la contingenza degli accadimenti, e dunque la libertà umana di autodeterminarsi e di poter agire diversamente da come agisce, dall'altra. All’interno di una tradizione generalmente orientata a privilegiare l’aspetto etico del problema e a ragionare dunque a partire dal fondamento indiscusso del libero arbitrio, abbiamo scelto invece di affrontare le soluzioni di quegli autori che hanno individuato la chiave per affrontare il dilemma compatibilista in una prospettiva legata ad atteggiamenti di natura epistemica, come “credere”, “conoscere”, “sapere”, e percettiva, come “vedere”.

The 26 essays collected in this volume explore some crucial aspects of the philosophical and scientific traditions of the Middle Ages and the Renaissance. Using a historical-philological approach, the volume brings to light unpublished documents and offers new reconstructions of the intellectual paths of authors such as Meister Eckhart, Nicole Oresme, John Buridan, Siger of Brabant, William of Ockham, Peter Pomponazzi, and Giovanni Pico della Mirandola.

In his Bipartitum in morali philosophia, the Scottish philosopher William of Manderston, a pupil of John Mair, and an Ockhamist philosopher, is quoting a text of Antonin of Padua who distinguishes the factum opened to a juridical qualification from the inner belief, known by God alone. Quoting the same text, the authors of the Malleus maleficarum try hard to distinguish three distinct fields, the inner beliefs which belongs to God, the exterior acts, the facts, which are relevant for the (...) judges, and the third field, which establishes a relation between the fact and the beliefs. This third field is proper to the inquisitors. Against this ethics of imputability, Manderston, relying on Ockham’s ethics, advocates an intentionalist ethics which depends on a sharp separation between interiority and exteriority. The soteriological dimension of the question entirely belongs to the inner life, whereas the exteriority is strictly disciplinary. By his radicality, Manderston appears as a paradigm of the modern dichotomy between conscience and law, Paolo Prodi once pointed out as a cornerstone of the religious modernity. (shrink)

The article studies some of the most important political ideas present in the origins of the modern State, especially the notion of political sovereignty, which, borne and developed in the maiestas of the imperial roman law and in the averroistic interpretation of the aristotelian idea of the perfect community, is accepted and developed by Francisco de Vitoria in the De potestate civili. Vitoria characterizes sovereignty with the features of supremacy in the domestic activity of the State and independence with regard (...) to other States. (shrink)

The sense of form that provides the modern poet with a unique experience of the literary object has been crucial to various attempts to compare poetry to other cultural activities. In maintaining similar conceptions of the relationship between poetry and painting, Arthur Rimbaud and W. C. Williams establish a common basis for interpreting their creative work. And yet their poetry is more crucially concerned with the sudden emergence of visible "worlds" containing verbal objects that integrate a new kind of literary (...) text. This paper discusses the emergence of "aesthetic worlds" in the work of both poets and then examines how a common concern with Baroque form unites them in the phenomenological task of overcoming Cartesian dualism.

The concept of moral wrongness, many think, has a distinctive kind of referential stability, brought out by moral twin earth cases. This article offers a new account of the source of this stability, deriving it from a metaphysics of content: “substantive” radical interpretation, and first-order normative assumptions. This story is distinguished from extant “reference magnetic” explanations of the phenomenon, and objections and replies are considered.

[This download includes the table of contents and chapter 1.] -/- When we praise, blame, punish, or reward people for their actions, we are holding them responsible for what they have done. Common sense tells us that what makes human beings responsible has to do with their minds and, in particular, the relationship between their minds and their actions. Yet the empirical connection is not necessarily obvious. The “guilty mind” is a core concept of criminal law, but if a defendant (...) on trial for murder were found to have serious brain damage, which brain parts or processes would have to be damaged for him to be considered not responsible, or less responsible, for the crime? The authors argue that evidence from neuroscience and the other cognitive sciences can illuminate the nature of responsibility and agency. They go on to offer a novel and comprehensive neuroscientific theory of human responsibility. (shrink)

This article proposes a new interpretation of mutual information. We examine three extant interpretations of MI by reduction in doubt, by reduction in uncertainty, and by divergence. We argue that the first two are inconsistent with the epistemic value of information assumed in many applications of MI: the greater is the amount of information we acquire, the better is our epistemic position, other things being equal. The third interpretation is consistent with EVI, but it is faced with the problem of (...) measure sensitivity and fails to justify the use of MI in giving definitive answers to questions of information. We propose a fourth interpretation of MI by reduction in expected inaccuracy, where inaccuracy is measured by a strictly proper monotonic scoring rule. It is shown that the answers to questions of information given by MI are definitive whenever this interpretation is appropriate, and that it is appropriate in a wide range of applications with epistemic implications. _1_ Introduction _2_ Formal Analyses of the Three Interpretations _2.1_ Reduction in doubt _2.2_ Reduction in uncertainty _2.3_ Divergence _3_ Inconsistency with Epistemic Value of Information _4_ Problem of Measure Sensitivity _5_ Reduction in Expected Inaccuracy _6_ Resolution of the Problem of Measure Sensitivity _6.1_ Alternative measures of inaccuracy _6.2_ Resolution by strict propriety _6.3_ Range of applications _7_ Global Scoring Rules _8_ Conclusion.

It is widely thought in philosophy and elsewhere that parsimony is a theoretical virtue in that if T1 is more parsimonious than T2, then T1 is preferable to T2, other things being equal. This thesis admits of many distinct precisifications. I focus on a relatively weak precisification on which preferability is a matter of probability, and argue that it is false. This is problematic for various alternative precisifications, and even for Inference to the Best Explanation as standardly understood.

There are two distinct approaches to Bayesian modelling in cognitive science. Black-box approaches use Bayesian theory to model the relationship between the inputs and outputs of a cognitive system without reference to the mediating causal processes; while mechanistic approaches make claims about the neural mechanisms which generate the outputs from the inputs. This paper concerns the relationship between these two approaches. We argue that the dominant trend in the philosophical literature, which characterizes the relationship between black-box and mechanistic approaches to (...) Bayesian cognitive science in terms of the dichotomy between instrumentalism and realism, is misguided. We propose that the two distinctions are orthogonal: black-box and mechanistic approaches to Bayesian modelling can each be given either an instrumentalist or a realist interpretation. We argue that the current tendency to conflate black-box approaches with instrumentalism and mechanistic approaches with realism stems from unwarranted assumptions about the nature of scientific explanation, the ontological commitments of scientific theories, and the role of abstraction and idealization in scientific models. We challenge each of these assumptions to reframe the debates over Bayesian modelling in cognitive science. (shrink)
