In this paper I shall discuss the relationship between the two known Arabic translations of Aristotle’s Posterior Analytics and Avicenna’s Kitāb al-Burhān. I shall argue that Avicenna relies on both (1) Abū Bishr Mattā’s translation and (2) the anonymous translation used by Averroes in the Long Commentary as well as in the Middle Commentary (and also indirectly preserved by Gerard of Cremona’s Latin translation of Aristotle’s work). Although, generally speaking, the problem is relevant to the history of the (...) transmission of the Posterior Analytics from Greek through Syriac into Arabic, I do not intend to give a systematic presentation of the historical setting in which Aristotle’s work became readily available to the Arabo-Islamic culture. My aim here is rather to isolate and discuss some pieces of evidence concerning the texts that seem to have been available to Avicenna. In addition to that, I shall also provide evidence concerning the relationship with the Greek commentary tradition (in particular Philoponus and Themistius) that is likely to have influenced Avicenna in his discussion of Aristotle’s theory of demonstration and scientific knowledge.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Before Science: The Invention of the Friars’ Natural Philosophy by Roger French, Andrew CunninghamIrven M. ResnickRoger French and Andrew Cunningham. Before Science: The Invention of the Friars’ Natural Philosophy. Hants, UK: Scolar Press, 1996. Pp. x + 298. Cloth, $68.95.This is a peculiar book that depicts thirteenth-century natural philosophy as wholly dependent on the theological interests of the mendicant orders. For the Friars, “Natural philosophy was a study (...) in which the central concerns were the detection, admiration and appreciation of God’s existence, goodness, providence, munificence, forethought and provision for His creation” (4). Although conceived as “a positive contribution to the discipline of the history of science” (3), the work begins and ends with the claim that medieval natural philosophers were not engaged in science.One difficulty is that the authors never make clear what they mean by science, although they evidently understand that it entails a repudiation of metaphysics and a doctrine of nature’s radical autonomy. Consequently, for French and Cunningham medieval “science” is a mythic construct of modern historians, since “[t]here was no scientific tradition (in the modern sense of the term ‘scientific’) of looking at nature in the thirteenth century, only a religio-political way of doing so” (273).Thus, when summarizing the accomplishments of Roger Bacon, they note that “[Bacon] has been credited, along with Grosseteste, with creating early ‘experimental science’. Bacon could not of course have been a ‘scientist’ because he lived in the wrong [End Page 623] age for this” (238). This seemingly casual conclusion is rather stunning not only in its own right, but also as a revelation of the authors’ own effort to disenfranchise medieval ‘scientists’ for having had the misfortune of living too soon.French and Cunningham propose that polemical or apologetical interests urged the Friars to study nature as a response to various heretics and especially the Cathars who, seemingly like moderns, sought to disengage the natural world from the Christian God, while using the vocabulary of Aristotle’s libri naturales. However this central argument demands better support. Since the authors can cite only one surviving Cathar text—De duobus principiis (ca. 1230)—almost everything known of this group is derived from anti-Cathar polemics. Based on this single text the authors can say no more than that it used “what looks very much like a commentary on Aristotle’s Physics or Metaphysics,” (134) but fail to identify more precisely its sources. It is clear that thirteenth-century orthodox polemics increasingly relied on Aristotelian materials, but the conclusion that natural philosophers did so only in response to heretics who beat them to the Aristotelian punch seems tendentious. The historian will likely remain unconvinced that the unparalleled translating activity of the late eleventh and twelfth centuries—the rendering into Latin of Arabic scientific knowledge (as in Constantine the African’s Pantegni or Adelard of Bath’s Quaestiones naturales), Greek medical literature (e.g. Galen’s Methodus medendi translated by Gerard of Cremona and Burgundio of Pisa) and mathematics (e.g. Euclid’s Optics, Theodosius’s Spherics, Archimedes’ On the Quadrature of the Circle, and Ptolemy’s Tetrabiblos and Almagest) culminating with thirteenth-century translations of Aristotle’s biological works—should all have stemmed from a preoccupation with heresy.A further shortcoming of this book is the limited attention given to works on natural philosophy by the Friars themselves. The book’s first seven of eleven chapters explore the educational establishments in which natural philosophy arose: first monastic and cathedral schools, and then the universities. The works of individual Friars receive only the briefest summary. Among the Dominican natural philosophers Albertus Magnus—the patron saint of scientists and one of a very few scholastics to have commented on all of Aristotle’s biological works—is awarded only five pages. For his mastery of Aristotle’s libri naturales Albertus has been called “the dominant figure in Latin learning and natural science of the thirteenth century.” (Cf. Lynn Thorndike, History of Magic and Experimental Science [New York: Macmillan, 1929], 2:521) Albertus described not only the natural world but also explored the philosophical foundations for scientific knowledge. Yet curiously French and Cunningham give much more attention... (shrink)

This study deals with Dominicus Gundissalinus’s discussion on metaphysics as philosophical discipline. Gundissalinus’s translation and re-elaboration of al-Fārābī’s Iḥṣā’ al-ʿulūm furnish him, in the De scientiis, a specific and detailed procedure for metaphysical analysis articulated in two different stages, an ascending and a descending one. This very same procedure is presented by Gundissalinus also in his De divisione philosophiae, where the increased number of sources –in particular, Avicenna– does not prevent Gundissalinus to quote the entire passage on the methods of (...) metaphysical science from the Iḥṣā’ al-ʿulūm, with some slight changes in his Latin translation. The analytical procedure herein proposed becomes an effective ‘metaphysical programme’ with regards to Gundissalinus’s onto-cosmological writing, the De processione mundi. The comparative analysis of this treatise with the procedure received by al-Fārābī shows Gundissalinus’s effort to follow and apply this metaphysical programme to his own reflection, in a whole different context from al-Fārābī’s and presenting doctrines quite opposed to the theoretical ground on which al-Fārābī’s epistemology is based, like ibn Gabirol’s universal hylomorphism. Nevertheless, thanks to the application of the ‘metaphysical programme’, one can effectively claim that Gundissalinus’s metaphysics is, at least in the author’s intentions, a well-defined metaphysical system. In appendix to this article the three Latin versions of al-Fārābī’s discussion on metaphysics are reported, e.g., Gundissalinus’s quotations in De scientiis and De divisione philosophiae, and Gerard of Cremona’s translation in his De scientiis.

This article reassesses the reasons why Toledo achieved prominence as a center for Arabic-Latin translation in the second half of the twelfth century, and suggests that the two principal translators, Gerard of Cremona and Dominicus Gundissalinus, concentrated on different areas of knowledge. Moreover, Gerard appears to have followed a clear program in the works that he translated. This is revealed especially in the Vita and the “commemoration of his books” drawn up by his students after his death. (...) A new edition of the Vita, Commemoratio librorum and Eulogium, based on all the manuscripts, concludes the article. (shrink)

It was a strange posthumous fate that awaited the Englishman Robert of Ketton : he was to be both best known and most strenuously criticized for a work that he surely viewed as a sideline to his own interests and career. By trade Robert was a Latin translator of Arabic scientific and mathematical works, one of those remarkable twelfth-century men who, as his contemporary Petrus Alfonsi put it, were willing “to traverse distant provinces and withdraw into remote regions so as (...) to be able to attain fuller knowledge of the astronomical art.” Like other contemporary translators, such as the Italian Gerard of Cremona , Robert had left his birthplace—in his case Rutlandshire—and traveled to Spain in order to have access to the great works of Arabic astronomy and mathematics that could be found in the still very Arab Iberian Peninsula. By 1141 we find him and his close friend Herman of Carinthia studying and translating scientific works together in northeastern Spain, and in later years his astronomical interests and ecclesiastical responsibilities led him to travel widely in Spain and England. As a scientific translator, he is perhaps best known for his Liber algebrae et Almucabola, a Latin version of al-Khwarazmī's great manual of algebra, Al-Kitāb al-mukhtaṣar fī ḥisāb al-jabr wa-al-muqābalah.

De scientiis: translation by Gerard of Cremona of (romanized: Ibsā al-ʻulūm)--De intellectu et intellecto: anonymous translation of (romanized: Risālah fi al-ʻaql).

The [[sic]] Arabic contribution to literary criticism is still very imperfectly known among Western scholars. It is important not only for the history of Arabic poetry, but for Latin Europe as well. Al-farabi’s discussion of poetry in his Catalog of the Sciences was translated into Latin by Gerard of Cremona and also incorporated into an important essay On the Division of Sciences by Dominicus Gundissalinus in the twelfth century. In 1256 Hermannus Almannus [[sic]] translated the Middle Commentary of (...) Averroës on Aristotle’s Poetics. This translation provided the first hazy glimpse of Aristotle’s theory of poetry available in the Latin west. It circulated widely in manuscript, it was printed in Venice in 1491, and it was reprinted in the Giunta editions of "Aristotle with Averroës" during the sixteenth century. (shrink)

The text of the tract De arcubus similibus was published for the first time by M. Curtze in 1887. However, after examining some more Latin manuscripts and the Arabic MS Oxford, Bodleian Library, Marsh 663 it appeared, that Curtze's edition was rather an adaptation. Also Curtze's suggestion that Jordanus Nemorarius was the author was very probably wrong. The author of the tract was the Egyptian mathematician Ahmed ibn Jusuf as appears from the Latin manuscripts, and its translator, very probably, (...) class='Hi'>Gerard of Cremona. In the tract Ahmed tried to prove, that the assertion ‘similar arcs are also equal arcs’ was wrong . His starting points were the propositions Euclid III, 20 and 21. Consequently, the tract can be looked upon as a commentary on the third book of the Elements. (shrink)

The purpose of this article is first to enrich the exposition on the contribution of the magistri artium in Claude Panaccio’s Le Discours intérieur by an in-depth scrutiny of a quotation from the Latin al-Fārābī ending the presentation of logic in the Divisio scientiarum (ca. 1250) of the Parisian Arts Master Arnoul of Provence (Arnulfus Provincialis). Once accomplished this revision using the various Latin versions or adaptations of the Farabian Enumeration of the sciences (Iḥṣāʾ al-ʿulūm) by Gerard of (...) class='Hi'>Cremona and Gundissalinus, it is clear that, despite a certain duality in its manuscript tradition, the relevant passage in Arnulfus Provincialis’s Divisio scientiarum does not merely distinguish inner logos and external logos, but also considers, like its source, a third logos, and that in a way susceptible to refine the characterization of al-Fārābī’s triadic logos as Le Discours intérieur reports this triade at the occasion of its judicious comparison with a parallel doctrine in John Damascene (Ekdosis akribès tès orthodoxou pisteôs alias De fide orthodoxa) interpreted differently by Thomas Aquinas following Albert the Great.

The twelfth century was a period of transmission and absorption of Arabic learning though it filtered outside of the Arabic world as early as the second half of the tenth century. In general, the lure of Spain began to act only in the twelfth century, and the active impulse toward the spread of Arabic mathematics came from beyond the Pyrenees and from men of diverse origins. The chief names are Adelard of Bath, Robert of Chester, Hermann of Carinthia and (...) class='Hi'>Gerard of Cremona. In this time the Latin world became acquainted with the Hindu numerals, the Arabic Algebra and Euclid'sElements. However, not only Spain, but also the Norman kingdom of southern Italy and Sicily occupies a position of peculiar importance, though the works of the translators did not become very influential. There were made direct translations from Greek into Latin. One had to wait a century more to obtain a translation from Greek into Latin of the chief Archimedean scientific and mathematical treatises by William of Moerbeke. In the thirteenth century Fibonacci and Jordanus Nemorarius stand at the threshold of European mathematics. Not only was Fibonacci the first to explain Arabic arithmetic, but his works, especially his later ones, contain many original ideas. Jordanus continued the Greco-Roman tradition rather than the Greco-Arabic one, but he did so with much independence. To Nicole Oresme (fourteenth century) was due a broadened view of proportionality, a geometric proof to determine the summation of convergent infinite series and the proof, evidently the first in the history of mathematics, that the harmonic series is divergent. The Configuration Doctrine was treated by Merton College authors and by Oresme. In the fifteenth century theDe triangulis omnimodis of Regiomontan, a systematic account of the methods for solving triangles, marked the rebirth of trigonometry. (shrink)

Although connectionism is advocated by its proponents as an alternative to the classical computational theory of mind, doubts persist about its _computational_ credentials. Our aim is to dispel these doubts by explaining how connectionist networks compute. We first develop a generic account of computation—no easy task, because computation, like almost every other foundational concept in cognitive science, has resisted canonical definition. We opt for a characterisation that does justice to the explanatory role of computation in cognitive science. Next we examine (...) what might be regarded as the “conventional” account of connectionist computation. We show why this account is inadequate and hence fosters the suspicion that connectionist networks aren’t genuinely computational. Lastly, we turn to the principal task of the paper: the development of a more robust portrait of connectionist computation. The basis of this portrait is an explanation of the representational capacities of connection weights, supported by an analysis of the weight configurations of a series of simulated neural networks.

When it comes to applying computational theory to the problem of phenomenal consciousness, cognitive scientists appear to face a dilemma. The only strategy that seems to be available is one that explains consciousness in terms of special kinds of computational processes. But such theories, while they dominate the field, have counter-intuitive consequences; in particular, they force one to accept that phenomenal experience is composed of information processing effects. For cognitive scientists, therefore, it seems to come down to a choice between (...) a counter-intuitive theory or no theory at all. We offer a way out of this dilemma. We argue that the computational theory of mind doesn't force cognitive scientists to explain consciousness in terms of computational processes, as there is an alternative strategy available: one that focuses on the representational vehicles that encode information in the brain. This alternative approach to consciousness allows us to do justice to the standard intuitions about phenomenal experience, yet remain within the confines of cognitive science. (shrink)

In this article we tackle the core question of machine emotion research – “Can machines have emotions?” – in the context of “social robots”, a new class of machines designed to function as “social partners” for humans. Our aim, however, is not to provide an answer to the question “Can robots have emotions?” Rather we argue that the “robotics of emotion” moves us to reformulate it into a different one – “Can robots affectively coordinate with humans?” Developing a series of (...) arguments relevant to theory of emotion, philosophy of AI, and the epistemology of synthetic models, we argue that the answer to this different question is positive, and that it lays grounds for an innovative ethical approach to emotional robots. This ethical project, which we introduced elsewhere as “synthetic ethics”, rejects the diffused ethical condemnation of emotional robots as “cheating” technology. Synthetic ethics focuses not on an ideological refusal, but on the concrete sustainability of the emerging mixed human-robot social ecologies. On this basis, in contrast to a purely negative ethical approach to social robotics it promotes an analytical case by case ethical inquiry into the type of human flourishing that can result from human-robot affective coordination.

This paper describes a novel perspective on the foundations of mathematics: how mathematics may be seen to be largely about “information compression via the matching and unification of patterns”. That is itself a novel approach to IC, couched in terms of nonmathematical primitives, as is necessary in any investigation of the foundations of mathematics. This new perspective on the foundations of mathematics reflects the facts that mathematics is almost exclusively the product of human brains, and has been developed, as an (...) aid to human thinking, mathematics is likely to be consonant with much evidence for the importance of IC in human learning, perception, and cognition. This perspective on the foundations of mathematics has grown out of a long-term programme of research developing the SP Theory of Intelligence and its realization in the SP Computer Model, a system in which a generalised version of ICMUP—the powerful concept of SP-multiple-alignment—plays a central role. This paper shows with an example how mathematics, without any special provision, may achieve compression of information. Then, it describes examples showing how variants of ICMUP may be seen in widely used structures and operations in mathematics. Examples are also given to show how several aspects of the mathematics-related disciplines of logic and computing may be understood as ICMUP. Also discussed is the intimate relation between IC and concepts of probability, with arguments that there are advantages in approaching AI, cognitive science, and concepts of probability via ICMUP. Also discussed is how the close relation between IC and concepts of probability relates to the established view that some parts of mathematics are intrinsically probabilistic, and how that latter view may be reconciled with the all-or-nothing, “exact,” forms of calculation or inference that are familiar in mathematics and logic. There are many potential benefits and applications of the mathematics-as-IC perspective. (shrink)

This is an extensive review of a book by three German scholars on the relationship between the baptismal questions and the Old Roman Creed, which also deals with the question of the authorship of the so-called Apostolic Tradition, dwells on the origin of the second, christological baptismal question and proposes a revolutionary new theory on the origin of the so-called Old Roman Creed. While there is much food for thought here, some critical questions can also be put.

This book assesses how Vatican II opened up the Catholic Church to encounter, dialogue, and engagement with other world religions. Opening with a contribution from the President of the Pontifical Council for Interreligious Dialogue, Cardinal Jean-Louis Tauran, it next explores the impact, relevance, and promise of the Declaration Nostra Aetate before turning to consider how Vatican II in general has influenced interfaith dialogue and the intellectual and comparative study of world religions in the postconciliar decades, as well as the contribution (...) of particular past and present thinkers to the formation of current interreligious and comparative theological methods. Additionally, chapters consider interreligious dialogue vis-à-vis theological anthropology in conciliar documents; openness to the spiritual practices of other faith traditions as a way of encouraging positive interreligious encounter; the role of lay and new ecclesial movements in interreligious dialogue; and the development of Monastic Interreligious Dialogue. Finally, it includes a range of perspectives on the fruits and future of Vatican’s II’s opening to particular faiths such as Judaism, Islam, Hinduism, and Buddhism. (shrink)

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Philosopher’s Demise: Learning FrenchPatrick HenryThe Philosopher’s Demise: Learning French, by Richard Watson; 133 pp. Columbia: University of Missouri Press, 1995, $22.50.An internationally known expert on caving and the life and works of Descartes, Watson writes traditional philosophical criticism as well as novels like The Runner (1981) and Niagra (1993). The Philosopher’s Demise, however, is the final part of a very loosely woven trilogy that is neither traditional (...) philosophical discourse nor fiction. These are certainly lighter texts than the ones on Cartesian metaphysics—indeed, they are all funny—but they also contain a good deal of practical philosophy.The Philosopher’s Diet. How To Lose Weight and Change the World (1985), for example, deals with the issue of fat, tells you how to get it off and keep it off but, in very lean prose, it also probes deeply into the form of commitment. It contains chapters on fat, food, and roughage but others entitled “Running,” “Sex,” “How to live,” and “How to die.” Fat functions here as a metaphor—it is “what clutters the unexamined life” (p. 26)—representing “the nagging triviality, the utter banality, and the inevitability of ordinary reality that separate us from what we think we want to be” (p. 145).With an occasional nod to Sartre (We are what we eat as we are what we do.) and Pascal (By altering our behavior, we can alter our beliefs.), Watson writes to provoke his readers to make a commitment to get the fat out of their lives, to take control of their actions and, perhaps, by changing themselves, to change the world. If we can, for example, “control [our] own eating habits apart from the norm imposed by society” (p. 75), we can begin to act as individuals in all other matters and completely transform our lives and, possibly, those of others. Watson, who contributed a chapter to World Hunger and Moral Obligation (1977) and who, during the 1960s, wrote a still unpublished volume entitled Sex and Revolution in which he claims that if people could revolt sexually against the [End Page 420] taboos of America, they could then perhaps be convinced to take control of the world’s food production, now remarks here, as if in passing, that if we fast for a day or two to make up for binges, we will get “a gut comprehension of what hunger really is for as many as a third of the world’s people” (p. 129). At its deepest level, The Philosopher’s Diet unveils an entire world obsessed with food—“the rich are worried about eating too much and the poor too little” (p. 56)—and underscores the immorality of not trying to change a system of food production and distribution in which we are overfed while millions are starving.The Philosopher’s Joke (1990) is a tougher book to get a handle on. It contains five chapters written in the dominant styles of philosophical writing popular in each of the last five decades. Two additional chapters complete the volume: “How to Die” which appeared almost verbatim in The Philosopher’s Diet and “A Pig’s Tail (The End of the Second Millenium).” As the book’s cover warns us, it is not always easy to ascertain the author’s position vis-à-vis the opinions reached in the specific essays. The first two chapters, though, are clearly parodies of purely formalistic writing, while the third is a skeptical but straightforward and serious attempt to establish that all interpretation is subjective. The fourth deals with deception in Kierkegaard and the themes of innocence sullied and human entrapment in Western culture. The main joke here has been played on Kierkegaard by God, “the original con man” (p. 87). Chapter six examines recent novels and films that treat the relationships between humans and apes and asks, seriously, what it would mean regarding animal rights and the place of human beings in the cosmos, if it could be shown that apes and humans can interbreed. Chapter seven brings the volume full circle. It shows how form carries content in its examination of the circular form, multiple circles, and epicycles of... (shrink)

Fast moving classical variables can generate quantum mechanical behavior. We demonstrate how this can happen in a model. The key point is that in classically evolving systems one can still define a conserved quantum energy. For the fast variables, the energy levels are far separated, such that one may assume these variables to stay in their ground state. This forces them to be entangled, so that, consequently, the slow variables are entangled as well. The fast variables could be the vacuum (...) fluctuations caused by unknown super heavy particles. The emerging quantum effects in the light particles are expressed by a Hamiltonian that can have almost any form. The entire system is ontological, and yet allows one to generate interference effects in computer models. This seemed to lead to an inexplicable paradox, which is now resolved: exactly what happens in our models if we run a quantum interference experiment in a classical computer is explained. The restriction that very fast variables stay predominantly in their ground state appears to be due to smearing of the physical states in the time direction, preventing their direct detection. Discussions are added of the emergence of quantum mechanics, and the ontology of an EPR/Bell Gedanken experiment. (shrink)

Despite hundreds of definitions, no consensus exists on a definition of life or on the closely related and problematic definitions of the organism and death. These problems retard practical and theoretical development in, for example, exobiology, artificial life, biology and evolution. This paper suggests improving this situation by basing definitions on a theory of a generalized particle hierarchy. This theory uses the common denominator of the “operator” for a unified ranking of both particles and organisms, from elementary particles to animals (...) with brains. Accordingly, this ranking is called “the operator hierarchy”. This hierarchy allows life to be defined as: matter with the configuration of an operator, and that possesses a complexity equal to, or even higher than the cellular operator. Living is then synonymous with the dynamics of such operators and the word organism refers to a select group of operators that fit the definition of life. The minimum condition defining an organism is its existence as an operator, construction thus being more essential than metabolism, growth or reproduction. In the operator hierarchy, every organism is associated with a specific closure, for example, the nucleus in eukaryotes. This allows death to be defined as: the state in which an organism has lost its closure following irreversible deterioration of its organization. The generality of the operator hierarchy also offers a context to discuss “life as we do not know it”. The paper ends with testing the definition’s practical value with a range of examples. (shrink)

One effect of information technology is the increasing need to present information visually. The trend raises intriguing questions. What is the logical status of reasoning that employs visualization? What are the cognitive advantages and pitfalls of this reasoning? What kinds of tools can be developed to aid in the use of visual representation? This newest volume on the Studies in Logic and Computation series addresses the logical aspects of the visualization of information. The authors of these specially commissioned papers explore (...) the properties of diagrams, charts, and maps, and their use in problem solving and teaching basic reasoning skills. As computers make visual representations more commonplace, it is important for professionals, researchers and students in computer science, philosophy, and logic to develop an understanding of these tools; this book can clarify the relationship between visuals and information.

Scientific breakthroughs rarely yield the potential to engage a foundational ethical question. Recent studies on direct reprogramming of human skin cells reported by the Yamanaka lab in Japan and the Thomson lab in Wisconsin suggest that scientists may have crossed both a scientific and an ethical threshold.

The ontological and ethical implications that accrue here are connected with the biological or natural potentiality of these cells. (shrink)

This paper identifies the key assumptions underpinning current arrangements in vocational education and training (VET) in the UK. These assumptions, and the idea of vocational capability they denote, are rejected in favour of a more coherent conception—a conception centred not on the traditional dichotomy of ‘knowing how-knowing that’ but on what I refer to as the ‘constitutive understandings’ from which both practical and theoretical capabilities can be seen to derive. It is argued that an account of vocational capability in these (...) terms suggests a far richer conception of vocational preparation than current arrangements are able to admit. (shrink)

Adam and Eve’s theft marks the beginning of the human career as moral agents. This article will examine the assumptions underlying the notion of moral agency from the perspective of three unremarkable human beings who found themselves in situations of moral difficulty.

It will conclude that it is unreasonable to assume that ordinary human beings will inevitably possess the resources to address difficult moral decisions.

In lieu of an abstract, here is a brief excerpt of the content:AN EXPLICATION OF THE DE HEBDOMADIBUS OF BOETHIUS IN THE LlGHT OF ST. THOMAS'S COMMENTARY HE WRITINGS o:f Ancius Manlius Severinus Boehius exercised a powerful influence on the nature and evelopment o:f mediaeval philosophy. The extent of his influence was such that I think it fair to say that anyone seeking more than a superficial grasp of mediaeval philosophy must acquire some first-hand knowledge of his work. The trouble (...) is, however, that while The Corwlsation of Philosophy is well-known and much commented upon, Boethius's other works are relatively neglected.1 Included in this latter group are the five theological tractates, one of which has this imposing title: Quomodo Substantiae In Eo Quad Sint Bonae Sint Cum Non Sint Substantialia Bona. This tractate also has the more managable title De Hebdomadibus and it is as such that I shall refer to it throughout this article.2 I have chosen to give an explication of the De Hebdomadibus for three reasons. First the problem with which it deals (the nature of the relation between goodness and substance) is intrinsically interesting and Boethius's solution to the problem is a model of philosophical analysis. Second, in addition to the fact that the philosophical status of the nine axioms listed in the tractate is a matter of some scholarly controversy, the answer to the obvious question of how these axioms function in the tractate as a whole is not at all clear. And third, this tractate is philosophically significant to those philosophers who take St. 1 I am obliged to Professor Ralph Mcinerny for awakening my interest in Boethius and for his suggestion that the De Hebdomadibus would repay careful study. 2 All references are to the H.

I shall begin my explication by giving a brief overview of the main lines of the tractate. Then I shall lay out the arguments contained in the statement and resolution of the dilemma which Boethius constructs, indicating (by means of Roman numerals in parentheses ) where I think particular axioms are meant to apply. Finally, I shall display the axioms as perspicuously as possible and comment on them. Overview The groundplan of the De Hebdomadibus is as follows. It begins with a brief introduction which contains the nine axioms. Then the problem to be considered is outlined in the form of the following dilemma. Things which are are good. This is the basic assumption which will generate the dilemma. Things which are good are so either by virtue of their substance or by participation. If they are good by virtue of their substance then, since God is the only substantial good, we arrive at an impious conclusion: we identify creatures with their Creator. lf they are good by participation then we generate a contradiction : things do and do not tend toward the good. Therefore, the conclusion must be that things which are are not good, which manifestly contradicts the basic assumption. Boethius's solution to the dilemma makes use of a thought-experiment. Abstracting from the first good he distinguishes locutions such as ' to be ' from locutions such as ' to be good.' On the basis of this distinction he is led to conclude that goodness is either a property of things or a principle of things. Re-introducing the notion of the first good, he notes that it is good by virtue of its very being. Secondary goods are also good by virtue of their being but only because that being derives from the will of the first good. Boethius cautions us against likening the being of particular things to the being of the first good and concludes the tractate by considering and refuting two objections to his solution. THE DE HEBDOMADIBUS IN THE LIGHT OF ST. THOMAS 421 The theme of the tractate is the problem of how substances can be good in virtue of their being without, at the same time... (shrink)

This chapter examines the role of law in European Union (EU) external relations from two perspectives. First, it examines the EU as a rule‐based (international) actor Law and focuses mainly on EU law‐ governs both the extent of the European Union's external powers and their exercise, the constitutional foundations of EU external relations and the legal principles that govern external action. Second the chapter turns to the European Union's characteristic use of law as an instrument and objective of its foreign (...) policy, the European Union as a promoter of a rule‐based international order. The role of the Parliament in the conclusion of international treaties, which are often regulatory or quasi‐legislative in character, brings to the final theme of this contribution: the role played by law as both an instrument and a goal of EU foreign policy.

Current research findings on metaphor in language and thought may be interpreted as producing a paradox of metaphor; that is, most metaphor is not processed metaphorically by a cross-domain mapping involving some form of comparison. This paradox can be resolved by attending to one crucial aspect of metaphor in communication: the question whether metaphor is used as deliberately metaphorical or not. It is likely that most deliberate metaphor is processed metaphorically (by comparison), as opposed to most nondeliberate metaphor, which may (...) be assumed to be typically not processed metaphorically (that is, by categorization). This resolves the paradox of metaphor because it suggests that all “metaphor in communication” (all deliberate metaphor) is processed metaphorically. Detailed comments are offered on the notion of metaphor deliberateness and on the nature of a three-dimensional model of metaphor in discourse involving metaphor in language, thought, and communication.
