This paper comprises two parts. The first part is an introduction to Auriol’s moderate conceptualism, as it is presented in his Commentary on Book II of the Sentences, distinction 9, question 2, article 1. The second part is an edition of the text. In the introduction, I focus on Auriol’s use of the noetic tool of connotation. My thesis, in particular, is that connotation is a necessary prerequisite to his moderate conceptu- alism. To this purpose, the first part of this (...) introduction will be devoted to a brief presentation of Auriol’s conceptualism. In the second part, Auriol’s theory of essential predication will be presented. In the third part, I will present my claim that Auriol’s theory of essential predication can only be made sense of when read against the background of his theory of connotation as applied to intellectual cognition. Finally, I will offer a collation of Auriol’s Commentary on Book II of the Sentences, dis- tinction 9, question 2, article 1, obtained by collating eight manuscripts, which hand down Auriol’s text, that is, Firenze, Biblioteca nazionale centrale, ms. Conv. Soppr. B.6.121, Firenze, ms. Conv. Soppr. A. 3.120, Napoli, Biblioteca nazionale, ms. VII.C.3, Padova, Biblioteca Antoniana, ms. 161, scaff. ix, Paris, Bibliothèque nationale de France, ms. latin 15867; Pelplin, Biblioteka Seminarium duchownego, ms. 46/85, Vaticano (Città del), Biblioteca Apostolica, ms.

_Sense Perception_ is the first part of the trilogy _Forms of Representation in the Aristotelian Tradition_. It investigates some of the most complex and intriguing aspects of theories of perception in the Greek, Latin, and Arabic reception of Aristotle’s psychology.

_Concept Formation_ is the final part of the trilogy _Forms of Representation in the Aristotelian Tradition_. It investigates some of the most perplexing and provocative discussions on conceptual thinking in the Greek, Latin, and Arabic reception of Aristotle’s psychology.

_Dreaming_ is the second part of the trilogy _Forms of Representation in the Aristotelian Tradition_. It investigates some of the most fascinating and enduring discussions on dreams in the Greek, Latin, and Arabic reception of Aristotle’s psychology.

Complexe significabilia are the significate of whole sentences, irreducible to what is signified by categorematic sub-sentential components. It has been propounded firstly by Adam Wodeham. Wodeham construes his argument for the postulation of complexe significabilia as a middle way between William of Ockham and Walter Chatton. According to Wodeham, Ockham’s view implies a reflexive theory of mental acts, which goes against the phenomenology of the act of assent. Moreover, it leads to an anti-realist epistemology. We need therefore things outside the (...) mind to be object of the act of assent, which is also the conclusion reached by Chatton. However, against Chatton, Wodeham argues that things signified by the categorematic component of sentences cannot be the object of assent. In effect, sentences with different syncategorematic structures, but with the same categorematic components, would correspond to the same propositional attitude in Chatton’s framework, which is an unwelcome consequence. The result is that we need to postulate that the objects of assent are outside the mind, contra Ockham, that are not signified by sentential categorematic components, contra Chatton, but are irreducibly signified by the whole sentences.

In this paper, I explore one line of argument for the Humean Theory of Reasons, the view that all normative reasons are based on desires. Then, I suggest a way to block that argument inspired by Aquinas’s discussions on choice, will, and indeterminacy of reason alone.

A linguagem mental explica o caráter significativo das linguagens falada e escrita: seus elementos e estrutura são identificados através de critérios teóricos que servem a este fim. Estes critérios parecem manter uma certa indeterminação em relação aos elementos e estruturas da linguagem mental, se se espera que eles decidam entre diferentes formas de apresentação possíveis. Esta expectativa, contudo, não é razoável dentro da filosofia ockhamiana. A teoria da linguagem mental pode desempenhar os papéis teóricos a ela destinados sem determinar a (...) forma que deveria ter uma linguagem canônica que a apresentasse. Há no entanto uma outra indeterminação na forma da proposição mental, relativa a ocorrências de proposições, que efetivamente ocorre nos textos ockhamianos : proposições mentais podem ser atos mentais simples e ter uma semântica composicional. Esta tese surpreendente nos lembra que embora a análise semântica que identifica estruturas da linguagem mental descreva algo que tem uma realidade psicológica, a descrição psicológica ela mesma deve recorrer a outros elementos da filosofia ockhamiana, e em particular, sua teoria dos atos mentais.

In the twelfth and thirteenth centuries, new ways of storytelling and inventing fictions appeared in the French-speaking areas of Europe. This new art still influences our global culture of fiction. Virginie Greene explores the relationship between fiction and the development of neo-Aristotelian logic during this period through a close examination of seminal literary and philosophical texts by major medieval authors, such as Anselm of Canterbury, Abélard, and Chrétien de Troyes. This study of Old French logical fictions encourages a broader theoretical (...) reflection about fiction as a universal human trait and a defining element of the history of Western philosophy and literature. Additional close readings of classical Greek philosophers Plato and Aristotle, and modern analytic philosophy including the work of Bertrand Russell and Rudolf Carnap, demonstrate peculiar traits of Western rationalism and expose its ambivalent relationship to fiction.

First critical edition of Petrus Thomae’s theory of non-causal dependence. This work of Scotist metaphysics is an investigation into the ultimate constitution of things. In the course of this treatise, Petrus Thomae examines whether the essences of things ultimately depend on being thought of by God for their very intelligibility or whether they have it of themselves. Defending in detail the second option, Peter argues that creatures exist independently of the divine intellect in the divine essence. They enjoy real, eternal (...) being in the divine essence and objective being in the divine mind. Aware that these views conflicted with his belief in the Christian doctrine of creation, Peter labored to alleviate the conflict with a theory of non-causal dependence, according to which even if God did not cause creatures to be in the divine essence, nevertheless they are necessary correlatives of the divine essence.

The present paper aims to reconsider our approaches to the suppositio theory (in the particular case of Peter of Spain`s Summaries of logic) in light of a new hypothesis of the double nature1 of medieval logic. Starting from the existing points of view, i.e. the theory of suppositio as a theory of reference and suppositio as a theory of an untranslatable, this paper will examine their underlying commitments to the nature of medieval logic. Such an analysis will entail for the (...) former approach a commitment to a formal nature, while for the latter to a non-formal one. The possibility of a new approach emerges when both natures can be traced in Peter`s theory. (shrink)

In The Political Animal in Medieval Philosophy Juhana Toivanen investigates what medieval philosophers meant when they argued that human beings are political animals by nature. He analyses the notion of ‘political animal’ from various perspectives and shows its relevance to philosophical discussions concerning the foundations of human sociability, ethics, and politics. -/- Medieval authors thought that social life stems from the biological and rational nature of human beings, and that collaboration with other people promotes prosperity and good life. Toivanen provides (...) a detailed philosophical interpretation of this view across wide range of authors, including unedited manuscript sources. As the first monograph length study on the topic, The Political Animal sheds new light to this significant period in western political thought. (shrink)

Perception of the external world is an essential part of the animal (including human) life, both as a source of knowledge and as a way to survive. Medieval authors accepted this view, and despite general concerns about the reliability of the senses in the acquisition of certain and objective knowledge, they thought that for the most part our perceptual system gets things right when it comes to the perceptual features of things—but not always. Our article focuses on thirteenth- and fourteenth-century (...) philosophical discussions of illusions and other types of perceptual errors. Reception of incorrect information, misjudgments concerning perceptual objects, the binding problem, and similar cases that explain perceptual errors will be analyzed. We discuss what might be called medieval Aristotelian/Avicennian theories of perception and the internal senses (drawing mainly from Albertus Magnus and Thomas Aquinas), as well as the so-called perspectivist accounts of perception, especially that by Alhacen. Finally, we take up a debate between Peter Auriol and his critics, which contains elements that can be seen as precursors of later skeptical worries. The concern here is that, just like in contemporary discussions leading to disjunctivism, the absence of a secure way to distinguish between veridical and non-veridical perception leads to a general worry about the reliability of our experience of the world.

The 13th-15th centuries were witness to lively and broad-ranging debates about the nature of persons. In this paper, I look at how the uses of ‘person’ in logical/grammatical, legal/political, and theological contexts overlap in the works of 13th-15th century contemplatives in the Latin West, such as Hadewijch, Meister Eckhart, and Catherine of Siena. After explicating the key concepts of individuality, dignity, and rationality, I show how these ideas combine with the contemplative use of first- and second-person perspectives, personification, and introspection (...) to yield a concept of 'person' that both prefigures Locke's classic 17th century definition and deeply influences the development of personalism.

In the twenty-seven questions translated in this volume, most never before published in English, William of Ockham considers a host of theological and philosophical issues, including the nature of virtue and vice, the relationship between the intellect and the will, the scope of human freedom, the possibility of God's creating a better world, the role of love and hatred in practical reasoning, whether God could command someone to do wrong, and more.

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 aims to address the widespread thesis according to which medieval scholastics would not handle the idea of fine art. Based on a suggestion by Anzulewicz, the author shows how Albert the Great did understand the peculiarity of fine arts and put them in close relationship with liberal arts. There are fine arts, such as music, which are sought after for their own sake and can, therefore, be considered as fully liberal. In contrast to them, there are other arts (...) called mechanical, whose purpose is utilitarian. In the third place, there are other arts which, although also possessing some utility, are chosen for their own sake and are therefore partly liberal; we should place fine arts such as architecture in that group. The more art participates in reason and the beauty of the soul, the more it will be fine and liberal. The product is called to be a metaphor for the honest good of virtue. The very contemplation of this beauty embodied by art evokes an aesthetic enjoyment. In this way, we can see that Albert, no less than Aquinas, speaks of the pleasure linked to the contemplation of beauty. (shrink)

According to the Dominican Thomas of Sutton, the reception of intelligible species in the potential intellect is in every point similar to the actualization of forms in matter, which means that the potential intellect remains completely passive through the whole process of concept acquisition. However, Sutton adds that when the intelligible species are stored in the memory and aggregate in logically organized clusters, thus becoming intellectual habitus, they have a way of being that is not found in material things, namely, (...) incomplete actuality. Without being properly speaking efficient causes of mental processes, they spontaneously tend to emerge by themselves into the light of awareness—even though other elements may in fact block them. This special sort of self-actualization is compatible, Sutton thinks, with the passivity he ascribes to the potential intellect. (shrink)

All medieval philosophers in the Aristotelian tradition agreed that the human intellect is not only able to know other things, but also itself. But how should that be possible? Which cognitive mechanisms are required for self-knowledge? This chapter examines three models that attempted to answer this fundamental question: (i) Thomas Aquinas referred to higher-order acts that make first-order acts and eventually also the intellect itself cognitively present, (ii) Matthew of Aquasparta appealed to introspection, (iii) Dietrich of Freiberg claimed that no (...) special cognitive process is necessary because the intellect is by nature always fully present to itself. An analysis of these three models shows that scholastic philosophers intended to provide an epistemological foundation for the explanation of Socratic self-knowledge. (shrink)

Due to his innatist theory, James of Viterbo brings original answers to a number of late-thirteenth century questions concerning cognition. While he maintains a certain distinction between the soul and its faculties, and among these faculties, he rejects the Aristotelian distinction between agent and patient intellects. Thanks to its predispositions to knowing, the mind is able to be an agent for itself. Correlatively, James rejects the usual conception of abstraction. Neither does the intellect act on the phantasms, nor the phantasms (...) on the intellect. The intellect simply actualizes a conceptual scheme at the occasion of adequate sensory representations. Since the innate predispositions are the intrinsic principles of cognitive acts, James maintains with Giles of Rome the notion of intelligible species. But he agrees with Godfrey of Fontaines that an act of intellection is nothing else than the fully actualized species itself. He also concedes to Henry of Ghent that the form of an intelligible object need not be ontologically received in the intellect, but can just have an “objective” presence. Finally, thanks again to his theory of predispositions, he has an easy solution to the vexed problems of the knowledge of substance essences and of the self. (shrink)

James of Viterbio is one of the rare medieval authors to sustain a thoroughly innatist philosophy. He borrows from Simplicius the notion of idoneitas (aptitude, predisposition) so as to ground a cognition theory in which external things are not the efficient and formal causes of mental acts. A predisposition has the characteristic of being halfway between potentiality and actuality. Therefore, the subject that has predispositions does not need to be acted upon by another thing to actualize them. External things only (...) “incline” the mind to make use of a stock of cognitive schemes. Consequently, in order to avoid an infinite regress James must adopt innatism. Following the lead of late Neoplatonism, he goes as far as including, not only conceptual schemes, but also perceptual schemes among the inbuilt stock. As a result, James’s theory, while it echoes certain preoccupations and themes that are common in the thirteenth century, proves to be one of a kind. (shrink)

According to the Dominican Thomas of Sutton (ca. 1250–1315), the reception of intelligible species in the potential intellect is in every point similar to the actualization of forms in matter, which means that the potential intellect remains completely passive through the whole process of concept acquisition. However, Sutton adds that when the intelligible species are stored in the memory and aggregate in logically organized clusters, thus becoming intellectual habitus, they have a way of being that is not found in material (...) things, namely, incomplete actuality. Without being properly speaking efficient causes of mental processes, they spontaneously tend to emerge by themselves into the light of awareness—even though other elements (other intelligible species, notably, or the will) may in fact block them. This special sort of self-actualization is compatible, Sutton thinks, with the passivity he ascribes to the potential intellect. (shrink)

The medieval notion of instrumental cause is not limited to what we call today “instruments” or “tools.” It extends way beyond the realm of technology and includes natural entities, for instance, the accidents by which a substance acts on another substance, sensible species in the air acting on a visual faculty, sacraments, bodily organs, and sometimes creatures with respect to God’s action. In all these cases, instrumental causes, like secondary causes in general, are subordinated to a principal cause and contribute (...) to its action and effects. However, the manner in which they do so makes them different from regular secondary causes, and the specifics are not easy to pinpoint. At the occasion of discussions about creation ex nihilo and sacraments, John Duns Scotus challenges Thomas Aquinas’s theory of instrumental causality. Whereas Aquinas does not strongly distinguish between artifacts and natural agents, and postulates a complex superposition of layers of causation, Scotus offers a novel view that clearly separates artificial instrumentality and natural instrumentality, and in both cases explains causation with great economy. Scotus’s in-depth discussion has far-reaching implications. It completely transforms the understanding of instrumental causality in general. (shrink)

In his Quadratura, Paul of Venice considers a sophism involving time and tense which appears to show that there is a valid inference which is also invalid. His argument runs as follows: consider this inference concerning some proposition A: A will signify only that everything true will be false, so A will be false. Call this inference B. Then B is valid because the opposite of its conclusion is incompatible with its premise. In accordance with the standard doctrine of ampliation, (...) Paul takes A to be equivalent to 'Everything that is or will be true will be false'. But he proceeds to argue that it is possible that B's premise ('A will signify only that everything true will be false') could be true and its conclusion false, so B is not only valid but also invalid. Thus A and B are the basis of an insoluble. In his Logica Parva, a self-confessedly elementary text aimed at students and not necessarily representing his own view, and in the Quadratura, Paul follows the solution found in the Logica Oxoniensis, which posits an implicit assertion of its own truth in insolubles like B. However, in the treatise on insolubles in his Logica Magna, Paul develops and endorses Swyneshed's solution, which stood out against this ''multiple-meanings'' approach in offering a solution that took insolubles at face value, meaning no more than is explicit in what they say. On this account, insolubles imply their own falsity, and that is why, in so falsifying themselves, they are false. We consider how both types of solution apply to B and how they complement each other. On both, B is valid. But on one (following Swyneshed), B has true premises and false conclusion, and contradictories can be false together; on the other (following the Logica Oxoniensis), the counterexample is rejected.

The fourteenth-century Greek hesychast and controversialist, Gregory Palamas, has been so successfully cast as "the other" in Western theological discourse that it can be difficult to gain a sympathetic hearing for him. In the first part of this book, Norman Russell traces the historical reception of Palamite thought in Orthodoxy and in the West, and investigates how "Palamism" was constructed in the early twentieth century by both Western and Eastern theologians (principally Martin Jugie and John Meyendorff) for polemical or apologetic (...) purposes. Russell argues that we need to go behind these ideological constructions in order to gain a true perception of the teaching of Gregory Palamas. In his recent survey of Palamite scholarship, Robert Sinkewicz noted that it is now time to raise the larger questions. The second part of the book attempts to do this, following the contours of Palamas' thinking in three areas: his relationship to tradition, his philosophy, and his theology. Russell shows that Palamite thought, when freed of misunderstanding and misrepresentation, has the potential to enrich our understanding of divine-human communion. This study contributes to the changing paradigm of scholarship on Palamas, nudging it towards the point at which Palamite thought can be used fruitfully by contemporary Western and Eastern theologians without the need to subscribe to what has been regarded as "Palamism".

This paper determines the state of mind, logic and language in medieval philosophy. It also exhibits the journey from medieval to early modern philosophy. In medieval philosophy, concept of mind was intimately connected soul or spirit with its harmony with religious tradition. Logic and language as well were corresponding with religion and faith. However in early modern philosophy the schema of mind, logic and language were different. These concepts were bailed from the clutches of religious dogmatism and faith towards the (...) mechanical correspondence. Mind was treated as non-modular. Logical truth which includes mostly inductive and deductive in medieval and modern period has been explained clearly. This paper shows the evolution of these concepts in the tradition of Rationalists, Empiricists and Critical Philosophers. In this paper I would as well show the interrelation between mind along with language and logic. This write up further shows the development of language in medieval period to early modern philosophy. it also demonstrates the footprints for the analytical study and international study in contemporary philosophy.

scientific progress, natural philosophy of the Late Medieval Period is seen as playing the role of apologetics. For philosophers of science, with their repudiation of metaphysics, the task of providing a rational reconstruction of how scientific progress has occurred is nigh on impossible. Even explanations such as the Popperian and the Kuhnian strain under great difficulty and provide only partly satisfactory results. In his “Logik der Forschung” (1934) Karl Raimund Popper argues that metaphysics plays an accidental part in the emergence (...) of new scientific ideas. Correspondingly, in “Structure of Scientific Revolutions” (1962), by carrying out theoretical interpretations and classification of empirical facts without their metaphysical premises, Thomas Kuhn comes to the conclusion that natural science was formed under the influence of erroneous interpretations of Aristotelian natural philosophy presented by medieval natural philosophers. These are some of the reasons why medievalists are still made to defend late medieval natural philosophy from shallow convictions that at medieval universities nothing of any significance to contemporary science and philosophy took place at all. Seeking to render a fragment of a coherent reconstruction of the development of natural philosophy, I will investigate one idea of late medieval philosophy – the explanation of motion (impetus). The main statement of the paper holds that the ideas of late medieval natural philosophy have a decisive significance for the development of modern natural science instead of accidental or negative one. In the paper, following Aristotelian philosophical approach, premises of Jean Buridan’s theory of impetus will be exposed. Then, debates over the explanation of projectile motion are going to be presented, and finally, the necessary significance of this metaphysical idea on the modifications of natural philosophy is going to be ascertained.

Some philosophers seem to argue that faith is or should be produced by arguments, whereas others describe faith as non-rational or even irrational. In the Summa Theologiae, Thomas states that arguments and miracles can show that faith is reasonable, even though unaided reason on its own cannot produce an act of faith. The insufficiency of reason for faith is a necessary condition of faith’s freedom and merit. The explanation of this insufficiency lies in the formal object of faith, which makes (...) the virtue and its acts essentially supernatural. Faith’s principles, namely the articles of faith, are seen to be true only by God and the blessed in heaven. Those who have faith assent to these revealed principles not though their natural ability, but through the “light of faith,” which is somehow similar to the “light of reason” by which humans assent to principles that are known through their terms. Faith’s supernatural character explains why reason is properly applied to faith only after one already possesses faith. It also explains how faith can be more certain than other intellectual habits, even though great uncertainty might arise on account of the believer’s imperfection. (shrink)

Medieval Aristotelians assumed that we cannot assimilate forms unless our soul abstracts them from sensory images. But what about the disembodied soul that has no senses and hence no sensory images? How can it assimilate forms? This article discusses this problem, focusing on two thirteenth-century models. It first looks at Thomas Aquinas’ model, which invokes divine intervention: the separated soul receives forms directly from God. The article examines the problems this explanatory model poses and then turns to a second model, (...) defended by Matthew of Aquasparta: the separated soul actively apprehends forms that are present to it. It will be argued that this model explains assimilation in terms of appropriation, rather than reception, of forms and thereby radically changes the traditional account of cognition. Finally, the article draws some methodological conclusions, arguing that the focus on the ‘limit case’ of separated souls made theoretical change possible. (shrink)

In this article, we publish the critical edition of Andalò di Negro’s De compositione astrolabii, with English translation and commentary. The mathematician and astronomer Andalò di Negro presumably redacted this treatise on the astrolabe in the 1330s, while residing at the court of King Robert of Naples. The present edition has three purposes: first, to make available a text missing from the previous compilations of works by Andalò di Negro; second, to revise a privately circulated edition of the text; and (...) third, to help disseminating one of the rare Latin texts presenting the principles of the stereographic projection which underlie the construction of the astrolabe.
