Proclus was one of the major Greek philosophers of late Antiquity. In his metaphysics he developed and systematized problems of Plato's thought, such as participation; transcendence - immanence; causation - participation - return; henads and monads; first and second causality. Before and after his works had been translated into Latin, Proclus influenced the Christian West through the _Liber the causis_, a Latin translation of an anonymous Arab version of Proclus' _Elementatio theologica_.

These are two of only three medieval treatises known to the editors explicitly devoted to discussion of concepts. That is not to deny that other works treat extensively of concepts among other matters.

Proposes an innovative rethinking of Aristotle’s work as a system that integrates his theology with his doctrine of reproduction and life. In this deep rethinking of Aristotle’s work, Abraham P. Bos argues that scholarship on Aristotle’s philosophy has erred since antiquity in denying the connection between his theology and his doctrine of reproduction and life in the earthly sphere. Beginning with an analysis of God’s role in the Aristotelian system, Bos explores how this relates to other elements of his philosophy, (...) especially to his theory of reproduction. The argument he develops is that in talking about the cosmos, Aristotle rejected Plato’s metaphor of artisanal production by a divine Demiurge in favor of a biotic metaphor based on the transmission of life in reproduction, in which pneuma—not breath as it is often interpreted but the life-bearing spirit in animals and plants—plays a key and sustaining role as the vital principle in all that lives. In making this case, he defends the authenticity of the treatises De Mundo and De Spiritu as Aristotle’s, and demonstrates Aristotle’s works as a unified system that sharply and comprehensively refutes Plato’s, and in particular replaces Plato’s doctrine of the soul with a theory in which the soul is clearly distinguished from the intellect. “Bos offers a fresh, interesting, and important perspective. His interpretation will be very controversial, but if he is right, the standard Anglo-American interpretation of Aristotle will have to change radically.” — Malcolm Wilson, author of Structure and Method in Aristotle’s Meteorologica: A More Disorderly Nature.

This paper contains a Dutch translation of the important text of Hippolytus of Rome on the Gnostic theology of Basilides of Alexandria. A summary of this theology is added together with some introductory remarks about whether or not Basilides received his doctrine from Matthias the Apostle, about the Aristotelean line of thought of Basilides, and about the relevance of modern study of Gnosticism.

The psychology of Aristotle has never been understood in a historically correct way. A new interpretation of the De anima will be proposed in which this work can be seen as compatible with the psychology that can be reconstructed from the fragments of Aristotle's lost dialogues and the De motu animalium and other biological works and the doxographical data gathered from ancient writers besides the commentators. In De anima, II, 412b5, where psychè is defined as 'the first entelecheia of a (...) natural body that is organikon,' the words 'natural body' should not be taken to mean 'the body of a living plant, animal or human being' but to stand for 'elementary body.' And the qualification 'organikon' should not be understood as 'equipped with organs' but in the sense of 'serving as an instrument to the soul.' This 'instrumental body' that is inseparably connected with the soul is the seat of desire, which physically influences the parts of the visible body. Besides those two corrections there are the words ta merè in 412b18 that should be taken as meaning not 'parts of the body' but 'parts of the soul.' Aristotle is arguing there that even those parts of the soul that are not yet actualized in the embryo of a new living being can be said to be 'not without body.'. (shrink)

This chapter contains sections titled: A Timeline of Medieval Logicians A Guide to the Literature.

In this article I argue that the heart of Aristotle’s philosophy was his doctrine of pneuma, which connected his psychology, biology, cosmology and theology, and which was central to his (lost and extant) works and should be taken into account, even where it is less explicitly discussed. Pneuma is not a sixth elementary physical body. It is the manifestation of the divine ether but always mixed with the other four elements within the sublunary sphere.

This anonymous source publication of a university discussion held in Prague about 1400 provides us with new information about medieval semantics after Peter of Spain and Richard Billingham. The edition is the basis of a partial reconstruction of Thomas of Cleves’ _Logica_.

It has been a long time ago since Professor De Rijk first drew our attention to an important Parisian manuscript containing two treatises on logic, both connected with the School of the 'Montani'. The school was established in the twelfth century on the Mont Sainte Genevieve (which is situated in what is nowadays known as the Quartier Latin). It was dominated by master Alberic (Albericus) of Paris. The 'Montani' were the heirs (faithful or not) of Pierre Abelard, Robert of Melun (...) and this master Alberic. The present work aims to provide a first working edition of one of the treatises in the manuscript, the 'Introductiones Montane Maiores'. This introductory work on logic contains a wealth of information about the way in which logic was taught and practiced in the schools of Paris of the twelfth century. It also gives insight into the vicissitudes of the teachings of different Parisian masters. The edition is preceded by an extensive introduction, with information about the origins and contents of the text and discussions of some interesting doctrinal elements. (shrink)

In this work, the papers are presented which, on the basis of L.M. de Rijk's monumental 'Logica modernorum' (1962-1967), sketch the development of medieval theories on meaning and reference from the beginnings well into the 17th century. The book also presents studies of these theories from a modern point of view.

Master Nicholas of Amsterdam was a prominent master of arts in Germany during the first half of the fifteenth century. He composed various commentaries on Aristotle’s works. One of these commentaries is on the logica vetus, the old logic, viz. on Porphyry’s Isagoge and on Aristotle’s Categories and On Interpretation. This commentary is edited and introduced here. Nicholas is a ‘modernus’ – as opposed to the ‘antiqui’, who were realists – which means that he is a conceptualist belonging to the (...) university tradition that accepted John Buridan (ca. 1300-1360 or 1361) and Marsilius of Inghen (ca. 1340-1396) as its masters. In medieval philosophy, a parallel between thinking and reality is generally upheld. Nicholas makes a sharp distinction between the two; this may be interpreted as a step towards a separation between the two realms, as is common in philosophy in later centuries. Other characteristics of Nicholas are that he defends the position that science has its place in a proposition, and does not simply follow reality. Furthermore, he emphasizes the part played by individual things. Fifteenth-century philosophy has hardly been studied, mainly because that century has long been considered unoriginal. Nicholas of Amsterdam certainly deserves the historian’s interest in order to evaluate how medieval philosophy prepared the way for modern philosophy. (shrink)

Background In the ethical and clinical literature, cases of parents who want treatment for their child to be withdrawn against the views of the medical team have not received much attention. Yet resolution of such conflicts demands much effort of both the medical team and parents. Objective To discuss who can best protect a child9s interests, which often becomes a central issue, putting considerable pressure on mutual trust and partnership. Methods We describe the case of a 3-year-old boy with acquired (...) brain damage due to autoimmune-mediated encephalitis whose parents wanted to stop treatment. By comparing this case with relevant literature, we systematically explored the pros and cons of sharing end-of-life decisions with parents in cases where treatment is considered futile by parents and not (yet) by physicians. Conclusions Sharing end-of-life decisions with parents is a more important duty for physicians than protecting parents from guilt or doubt. Moreover, a request from parents on behalf of their child to discontinue treatment is, and should be, hard to over-rule in cases with significant prognostic uncertainty and/or in cases with divergent opinions within the medical team.

Why do all animals possess sense perception while plants don’t? And should the difference in quality of life between human beings and wolves be explained by supposing that wolves have degenerated souls? This paper argues that for Aristotle differences in quality of life among living beings are based on differences in the quality of their soul-principle together with the body that receives the soul. The paper proposes a new interpretation of On the Soul 2.4.415b18: “For all the natural bodies are (...) instruments of the soul,” against all current interpretations. Aristotle there means that each of the four sublunary elements can be a part of the instrumental body of a soul. The paper continues with discussing the way in which Aristotle connects the several sublunar elements with different levels of life activity, and the troublesome passage in Generation of Animals 3.11.761b22, where Aristotle speaks about a fourth category of living creatures related to the fourth sublunary element, Fire, and the region of the Moon.

This volume contains 14 studies on various aspects of Duns Scotus' philosophy. Duns Scotus is one of the most important philosophers of the Middle Ages. His radical conception of contingency means a break in the history of thought. Despite his importance, he has not yet been studied very much. The contributors to the volume discuss a.o. Duns' view on will and intellect, on the law of nature, on man, and on aspects of his logic and metaphysics.

Hippolytus of Rome on Aristotle’s definition of the soul. His work Concerning the Soul is obscure. For in the entire three books [where he treats of his subject] it is not possible to say clearly what is Aristotle’s opinion concerning the soul. For, as regards the definition which he furnishes of soul, it is easy [enough] to declare this; but what it is that is signified by the definition is difficult to discover. For soul, he says, is an entelecheia of (...) a sôma physikon organikon; [but to explain] what this is at all, would require a very great number of arguments, and a lengthened investigation.

Die Erforschung Kants ist langst zu einem weltumspannenden Unternehmen geworden. Welch reiche Frucht der Wissenschaft dadurch zufallt, zeigen die Beitrage dieser Festschrift, die dem Nestor der deutschen Kantforschung, Norbert Hinske, gewidmet ist. Bekannte Vertreter der italienischen, japanischen, russischen und deutschen Kantforschung kommen zu Wort. Von besonderer Bedeutung fur die - in diesem Punkt ganzlich neu zu schreibende - Lebens- und Entwicklungsgeschichte Kants ist ein neu entdeckter, erstmals im Faksimile abgedruckter Brief von J. E. Biester an J. N. Tetens, der belegt, (...) dass der preussische Kultusminister v. Zedlitz zunachst nicht etwa Kant, sondern Tetens nach Halle berufen hat. Hinskes vollstandige Bibliographie rundet den Band ab - und zeigt eindrucksvoll, wie viel die Kantforschung weltweit gerade ihm zu verdanken hat. The study of Kant has long been a global undertaking. The articles in this Festschrift for the leading German expert on Kant, Norbert Hinske, show how richly productive this has been for scholars. Leading Italian, Japanese, Russian and German representatives of research on Kant have provided contributions to it. What is particular significant for the history of Kant's life and development, which has to be completely rewritten in this regard, is a newly discovered letter, reprinted in facsimile for the first time, from J. E. Biester to J. N. Tetens, which proves that Prussian Minister of Culture v. Zedlitz initially did not appoint Kant but rather Tetens to the position in Halle. Hinske's complete bibliography is included in the volume and is impressive evidence of how much Kant research worldwide owes to him. (shrink)

This paper explores the educational significance of the critique of representationalism. As it includes the notion of non-representational knowledge, Rudolf Steiner’s epistemology is introduced and further linked to elements in Bergson and Deleuze. Humboldt’s idea of Menschenbildung as the central function of knowledge is brought in, since both Humboldt and Steiner emphasise knowledge as mediating the interplay between self and world, producing a deeper sense of reality. Such an education must respect the living nature of genuine concepts as well as (...) the aesthetic aspects of learning. After a note on the educational abuse of language in discursive closures, some traits of Steiner’s practical pedagogy are presented as possible practical implications. (shrink)

Starting with Jaakko Hintikka’s seminal work, epistemic logic has now grown up to a huge academic industry. When we look back to its history, however, there is a practical paradox. While Hintikka’s original purpose was to facilitate epistemological discussion, most subsequent work of epistemic logic has been done outside of philosophy, and has been ignored by most mainstream epistemologists. At the current point, one might naturally wonder, does epistemic logic still have something to do with epistemology? Along with Hintikka and (...) a growing number of formal epistemologists, we believe the answer is “yes”. Contemporary epistemology has largely focused on the goal of providing an analysis of knowledge and an answer to skepticism. To avoid skepticism, many epistemologists prefer to define knowledge in terms of evidence and relevant alternatives. A typical saying is that “in order to know that p, one only needs evidence to eliminate all relevant alternatives, rather than all alternatives”. We see such a project as perfectly congenial to the spirit of Hintikka’s epistemic logic. In this paper, we propose an epistemic logic to deal with evidence and relevant alternatives explicitly, and extend EREL to its dynamic version to investigate how different notions of knowledge behavior with the decrease and increase of relevant alternatives. To illustrate its philosophical application, we provide a new formalization of the so called factivity problem of epistemic contextualism. We conclude with some remarks on further developments of our framework. (shrink)

The modern debate over the hellenistic doctrine of the fine-material soul-vehicle, including contributions by R. C. Kissling, E. R. Dodds, and J. Halfwassen, has seen an increasingly earlier date of origin being attributed to this doctrine. But the author who introduced the theory remains an unknown quantity. In this article I will argue that the author of this doctrine can be no other than Aristotle.

On the Soul II 8, 420a3–12 is always explained as if Aristotle there considered the ears to be the seat of the faculty of hearing. However, Aristotle there identifies the instrument of sense perception not with external parts of the visible body but with the soul’s instrumental body, situated in the heart and connected with the ears. That also appears to be the case in Generation of Animals V 2.
