" The collectaneous manuscript Paris, B.N. lat. 16.096 (formerly belonging to the codices Sorbonnenses) contains (ff. 172va-177vb, which part
dates, it seems, from the second half of the 13th century) some anonymous questions referred to by the catalogue (*) as Quaestiones super librum Posteriorum.
This description, however, is incorrect as these questions have no bearing whatsoever on the doctrine of Aristotle's Posterior Analytics. Actually, they are
two short metaphysical questions (called expositiones by the author) on the key notions of 'beingness' and 'oneness' respectively, followed by a longer,
incomplete treatise on the nature of the components of a definition (or rather a diffinitum).
Only two of the five questions announced in the beginning of this third treatise are preserved. One of them deals with the problem of whether
the definition consisting of genus and differentia requires a real composition of the components of the diffinitum, the other examines whether immaterial
substances are composite in some respects. Unlike the first two tracts, the third does not show any influence of Neoplatonic doctrine.
To my knowledge, the expositions on Ens and Unum have only come down to us in the Paris manuscript. They are interesting in that the author
makes a successful effort to penetrate some of the basic views of Proclean metaphysics." pp. 1-2 (notes omitted)

Peter, of Spain. 1992. Peter of Spain. Syncategoreumata. Leiden: Brill.
First critical edition with an introduction, critical apparatus, indexes and an English translation by Joke Spruyt.
Peter of Spain (ca 1205-77) who, in 1276, became Pope under the name of John XXI, was the author of an impressive number of scholarly works,
inter alia the Tractatus (a textbook of logic, widely known afterwards under the title Summule logicales) and the Syncategoreumata. The latter work, which
deals with syncategorematic terms, is here critically edited for the first time, together with an English translation.
Peter's authorship of the Syncategoreumata is beyond all doubt: it is confirmed again and again by nearly all our manuscripts. As to the date
and place of origin of the Syncategoreumata: they were surely written after the Tractatus (which were written not later than the 1230's, see my Introduction to
the edition of this work, p. LV-LVII).
There is no reason at all to assume a connection between the Syncategoreumata and Peter's stay at the University of Paris, which he left in
1229, before the composition of the Tractatus. Clearly, Paris does not play any role in the early diffusion of the Syncategoreumata. It seems highly probable,
therefore, that the Syncategoreumata were written by Peter in the same region where he wrote the Tractatus, i.e. Northern Spain or Southern France. The work's
most likely date is between 1235-1245 (cf. my Introduction to the Tractatus, pp. XXXIV-LXI). From Peter's use of lectio (see X, cap. 8) it may be concluded
that the Syncategoreumata were meant as a piece of school-teaching.

"It is common knowledge that Plato strongly believed that, in order to explain the nature of whatever is (either things or states of affairs,
including Man and his environment), the assumption of Transcendent Universal Forms is indispensable. In his view, these universal Forms are the ontic causes of
each and every sublunary entity, which all owe their being to their sharing in these Forms. Consequently, everyone who is in want of firm knowledge
(episteme) about, the things of the outside world is bound to direct his attention to the transcendent domain of the universal Forms'.
However, Plato was the first to recognise, and seriously deal with, the objections that can be raised to this doctrine. These objections
mainly concern the status (and the dignity, however modest) of our transient world and, above all, the possibility to obtain, true knowledge of this world as
it stands, in its ever-changing nature, that is." p. 35
"To be sure, the Medievals all rejected the Platonic Ideas taken as separate substances and they adhered to the Aristotelian common sense
principle that only individuals have independent existence. Nevertheless, they were still under the spell of the status of «universal being» as the
indispensable basis of true knowledge.
Marylin McCord Adams has analysed some early fourteenth century solutions to the problem of universals (Scotus, Ockham, Burley and Harclay)
(*). In McCord's article Buridan's view of the matter is left out of consideration. Quite understandably so, since Buridan's solution to the problem differs
considerably from the sophisticated arguments given by his contemporaries. Buridan seeks.for a solution in analysing the several ways of human understanding.
In directing his attention to the propositional attitude involved in the cognitive procedure Buridan is remarkably close to the ingenious solution Peter
Abelard had come up with two centuries earlier. In the next sections I shall give an outline of Abelard's treatment of the question of universals
followed by an analysis of Buridan's discussion of the matter (as found in his commentary on the Metaphysics and elsewhere)." p. 37
"We may conclude, then, that two bright logicians of the Parisian tradition have come up with quite an ingenious solution to the problem of
universals. Both of them started out from the firm conviction that nothing exists but particulars. Nevertheless, they apparently were not satisfied with purely
extensional solutions as brought forward by Oxford logicians such as Heytesbury and Ockham. Maybe extensionalists are out to show how people ought to
think. Abelard and Buridan, however, were especially interested in the various ways of conceiving we actually use in daily life, in our attempts to
conceptually deal with the outside world." p. 59

"One of the most striking characteristics of late medieval metaphysics is the upgrading of 'accidental being'. The strict opposition between
'esse per se' and 'esse per accidens', which had been of paramount importance ever since Aristotle, has lost its relevance in the ontological
discussions of the fourteenth century. The status of 'accidental being' came rather close to that of 'substantial being'. In the views of philosophers such as
Ockham and Buridan (not to mention thinkers like Crathorn) the nature of 'accidental being' (or rather 'quantitative and qualitative being') can no longer be
properly defined in terms of ontological dependency upon substance. In other words, 'per se subsistence' is assigned not only to substance but to
'accidental being' as well.
In the present contribution I will illustrate this development by discussing some of Buridan's expositions in his Questiones
commentary on Aristotle's Metaphysics (IV, q. 6 and VII, q. 3-4)." p. 41

"Some twenty years ago I discovered in the Biblioteca Nacional in Madrid a very interesting manuscript with works (all of them anonymous, to
be sure) on logic, metaphysics and natural philosophy. In fact, my discovery turned out to be a rediscovery, for the manuscript contained a note written by the
famous historian of Franciscan philosophy and theology, Father Ephrem Longpré OFM, which said that, with the exception of the writings occurring from fol. 204r
onwards, all tracts found in this codex are by a Franciscan master, Gerardus Odonis. (...)
Gerard Odon OFM (who as Patriarch of Antiochia died in 1349 of the plague, at Catania, Sicily, where he was gifted with the benefices of a
wealthy church) is especially known as the much troubled successor of the deposed Michael of Cesena as Master General of the Franciscan Order and a close
adherent of Pope John XXII in the debate on the beatific vision." p. 173
"The Ms Madrid, Bibl. Nac. 4229 appears to be of the utmost importance for our knowledge of Gerard Odon's doctrine on several subjects in the
fields of logic, metaphysics and natural philosophy. To establish his authorship of all the works as occurring in the present Ms with certainty requires more

"As is well-known, two subjects are distinctive of the fourteenth century theory of cognition, namely 'certitudo' and
'evidentia'. It is true, thirteenth century philosophers, such as Thomas Aquinas, were also concerned with certitude and evidentness as indispensable
requisites for 'true knowledge' ('scientia'). However, until the end of the thirteenth century certitude and evidentness were not prominent in the
discussions about the cognitive procedure nor were they treated as separate matters, requiring separate attention. In Thomas Aquinas for example, the
conviction that man is really capable of grasping the truth with certainty is really constitutive of his philosophical (and theological) thought and praxis
(*)', or to speak with J. A. Aertsen, of 'Thomas' way of thought'.(**) This, however, does not alter the fact that in Aquinas' philosophy 'certitudo' is not
highlighted as such, and the specific role of 'evidentia' is even virtually ignored.
Buridan's theory of cognition, on the contrary, clearly focusses on the ingredients 'certitudo' and 'evidentia', and,
within this framework, on the notion of 'assensus'. In the present paper I aim to elucidate the role of this key notion of John Buridan's theory of

"In the opening lines of the fifth tract of his Summulae Peter of Spain deals with six different meanings of the terminus technicus 'ratio'.
Three of them are relevant to the present discussion:
'Ratio' is used in more than one way. In one way it is the same as definition or description, as in «univocal things are those which have a
name in common and whose 'ratio substantie' corresponding to that name is the same» (b) [...]. In another way 'ratio' is the same as the form imposed on matter
(forma materie), e.g. in a knife iron is the matter and the arrangement imposed on the iron is the form. In yet another way 'ratio' is the same as a common
essence that is predicable of many things, e.g. the essence of a genus, a species or a differentia. [...].
The aim of the present paper is to elucidate the important role of the term 'ratio' in metaphysical discussions from the thirteenth century
onwards. The three above mentioned senses all refer to (what belongs to) a thing's essential nature. The first sense, however, is the one that comes
most close to the subject matter of our discussion. (c) The opening lines of Aristotle's Categoriae, which are referred to by Peter may serve
as the starting point of our investigation." p. 197
We may summarise the foregoing observations as follows:
(1) As early as in Boethius (Aristotle) ratio (Greek 'logos') was used to stand for one specific (ontic or logical) characteristic
that a thing has in common with other things, notwithstanding the dissimilarity of their respective 'complete natures'. Thus 'man' and 'cow' have the ratio
animalis in common and a white wall and a white statue have whiteness in common.
(2) Ratio may also be used to refer to a thing's 'complete nature' as distinct from either the nature of other things (e.g. the
ratio hominis vs the ratio lapidis) or from the thing's individuality (ratio singularitatis).
(3) Distinguishing several rationes in one and the same thing is a procedure which is typical of man's intellectual capability. This
procedure forms the backbone of many philosophical and theological arguments concerning God and the entities occurring in the outside world.
(4) Possible translations of ratio as used in the special sense discussed in this paper are:
- logically: 'logical aspect', 'logical characteristic'; 'concept', 'notion' (bearing on some aspect characteristic or feature);
'meaning', 'descriptive account', 'definition'.
- ontologically:'ontic aspect', 'characteristic', 'feature' (including formal ones)." p. 218

"The present edition contains the second tract [of Buridan's Summulae], De praedicabilibus, which deals with the five
'predicables', introduced by the Neoplatonist commentator of Aristotle, Porphyry (c. 233-c. 304 A.D.) in his introductory book (Isagoge) to the
Stagirite's Categories, viz. 'genus', 'species', 'differentia', 'proprium', and 'accidens'. From as early as the eleventh century, medieval authors
commented upon Boethius' (480-524) translation of, and commentary upon, this work.
Buridan's discussion of the predicables is mainly based on the corresponding tract of Peter of Spain's manual. His comments are preceded by
the complete text of the lemma from Peter to be discussed. It should be no surprise that Buridan's quotations should go back to an adapted version of Peter's

"The present paper aims to clarify the attitude towards Aristotle adopted by one of the leading lights of fourteenth century philosophical
and theological thought, William of Ockham, by investigating (a) how in some of the vital subjects of Aristotelian doctrine, the Venerable Inceptor understood
and interpreted the Master, (b) how and why on specific occasions, he deliberately took the liberty to stray from Aristotle's teachings. It goes without saying
that in such an undertaking, one has to confine oneself to certain doctrinal themes the choice of which might seem quite arbitrary. The present author has
picked out the Aristotelian doctrine of demonstrative proof as interpreted by Ockham." p. 78

"Everyone embarking on the theme 'Medieval Latin and Philosophy' should realise that this theme involves more than just a juxtaposition of
two separate items which are quite interesting in themselves. On the contrary, Medieval Latin and philosophy had a great mutual impact and thus were most
closely related. To put it differently, in Medieval philosophical teaching and inquiry linguistic analysis was considered by the Medievals themselves really
Like the Ancients, the Medieval thinkers firmly believed that, ultimately, the outside world is not-chaotic. In their view it has a 'logical'
or intelligible structure, which, as such, is accessible to the human mind, insofar as the latter has the same 'logical' structure'. In other words, in the
view of the Medievals there is an isomorphic relationship between the realms of thought and of being. (**)
The Medievals have largely expanded the logico-semantical approach they had inherited from the Ancients, especially in their so-called
'logica modernorum', which has its root in the logico-grammatical discussions found as early as in the eleventh century.
Coming now to the proper subject of my contribution I should like to discuss three extremely important themes that featured in Medieval
philosophy, viz.  the 'Object-Thought' issue,  the problem of the Universals, and  the metaphysics of 'Accidental Being'. Our discussion will focus on
the linguistic aspects of the solutions to each one of these problems. Three things in particular will be considered: [a] the semantical development of a
terminology which was already common usage (e.g. 'idea', 'ratio'), [b] the introduction of new philosophical tools (e.g. 'suppositio', 'appellatio',
'connotatio'), and [c] the role of (artificial) word-order. I shall argue that for the Medievals, the Latin language was not only the vehicle of philosophical
thought, but also an inspiring source of pioneering philosophical insight." pp. 129-130.

"By and large, in De interpretatione Aristotle is concerned with our capability to speak about all that presents itself to our mind.
From chapter 4 onwards, he deals with the statement-making expressions (affirmation and negation), which are the main tools for conveying our thoughts about
things. This discussion is prepared (chapters 1-3) by some important observations concerning the basic elements of such expressions, viz. onoma and
rhema. The present contribution contains some comments on Aristotle's view of the proper nature of statement-making as put forward in De
interpretatione. First, I would like to highlight Aristotle's, what Sir David Ross has called 'frankly 'representative' view of knowledge' by discussing
the terms omoioma and pragma. Next, I will discuss what is meant by a term's 'time-connotation', and finally I will examine the semantics of
onoma, rhema and logos." p. 115

"The extensive list of works by Walter Burley contains a collection of some eagerly disputed questions concerning natural philosophy, which
in most of the manuscript catalogues goes under the blank title Tractatus primus. (...)
In the shorter version of his Expositio super librum Sex principiorum, written after he had left Paris in 1327, he deals with the
position concerning the specific sameness of whiteness and blackness he had argued for ín the fourth quaestio, and refers to his 'primus tractatus
de formis accidcntalibus" (...)
This reference seems to imply that the title 'De formis accidentalibus' covers both the Tractatus primus and the
Tractatus secundus, which was afterwards called 'De intensione et remission formarum.' I think it would be better to call the first treatise
'De formis accidentalibus, pars prima,' with the subtitle 'De quattuor conclusionibus circa formas accidentales'. The second treatise, then,
which contains a discussion of a closely related subject matter, should go under the title 'De formis accidentalibus, pars secunda,' with the subtitle
'De causa intrinseca susceptionis magis et minus'. Later on, its current tide became De intensione et remissione formarum." pp. 161-162

in print for the first time as a whole. Generally speaking, the work is well-composed and written in a lucid style. The Addenda even contain rather
passionate passages, when Girald is rejecting opponent views, especially in those cases where Walter Burley is (anonymously) under attack. The characteristic

"As we have remarked before, Girald's tract on "the two most common and well-founded principles of knowledge" is the most original part of
his Logica. To assess its place in Girald's thought requires an investigation into the proper nature of the two principles and what the Medieval
commentators used to call the 'conditions' ('specific properties') of these principles, as well as what to Girald's mind plays the key role in such an inquiry,
the proper subject of logic. I shall deal with these themes here briefly; they will be extensively discussed in our Introduction to the edition of

"7. Conclusion. To Odonis' mind, statemental being is a kind of being sui generis, so to speak, which, no doubt, is something more
than a kind of being that entirely owes its existence to the soul's activity. Rather Odonois' statemental being should be regarded as the metaphysical
indivision (in as far as, on the statemental level, affirmative sentences are concerned), or division (in the case of negative sentences) which exist in the
realm of the natura communis. Thus, statemental being is the basic precondition for the existence of both real being and conceptual being, to the
extent that within the domain of the natures communis it specifically concerns the ontological (whether essential or incidental) relationships of
indivision and division that exist between the common natures. When defending against his numerous opponents the real character of statemental being, Odonis
has the metaphysical reality of the realm of the common natures in mind, rather than the reality of the actual world. To put it briefly, like his doctrine of
the nature of the universal, Odonis' view of statemental being clearly betrays a Platonic flavour, which makes him join the camp of the extreme realists." p.

"One of the most original works by the Franciscan Master Gerardus Odonis (Guiralt Ot) is the third part of his Logica, De principiis
scientiarum. This treatise is not just a commentary on Aristotle's Posterior Analytics, nor is it a specialized treatment of its subject matter,
which is demonstrative (or rather epistemonic) knowledge, as is found in Ockham's Sum of Logic. Rather, Odonis took his treatise to be a supplement to
the Aristotelian work, where the demonstrative principles proper to the different 'sciences' (principia propria) as well as those they all have in
common (principia communia) are extensively discussed by Aristotle, but less attention is paid to the most common principles of the intellect
(principia communissima intellectus), such as the twofold principle of noncontradiction. What Odonis means to do, then, is to discuss the well-known
seven requirements concerning the proper and the common principles insofar as they apply to the principle of non contradiction (henceforth PNC).
Accordingly, the author has divided his treatise into ten chapters, the first of which deals with the subject matter of PNC and its
constituents or terms. This chapter presents first ten basic assumptions (suppositiones), next twelve theses (conclusiones) together with the
discussion of a number of notable statements (notabilia) and corollaries, and finally the refutation of objections (dubia).
In the present paper the conclusiones 6-11 concerning the nature of being as involved in PNC will be discussed." pp. 51-53

"Introduction. Pendant tout le Moyen Age, comme durant la période patristique, les penseurs chrétiens se sont beaucoup intéressés aux
rapports entre la raison et la foi. On sait que le principal thème de recherche et de discussion, en ce domaine, était l'harmonisation de la foi et de la
raison, ce qui revenait au début à faire une apologie du le caractère rationnel de la foi, mais ce qui, chez des géants comme Anselme ou Abélard, a conduit à
une élaboration de la théologie grâce à l'emploi de ce que notre collègue, Jean Jolivet, dans son étude de pionnier sur la théologie d'Abélard, a si
heureusement appelé les « arts du langage (1) ». D'autre part, les penseurs médiévaux ont toujours reconnu l'importance du « dépôt de la foi » en tant que
collection des vérités garanties, si bien que l'on prenait ces vérités pour des renseignements supplémentaires sur les phénomènes terrestres. Le simple «
Soleil, arrête-toi » de Josué (Livre de Josué 10, 12) a suffi pour maintenir le système géocentrique.
A partir de la deuxième moitié du XIIIe siècle, c'est surtout la toutepuissance divine et la contingence radicale de tout le créé qui
conduisent certains penseurs à regarder le monde d'un point de vue tout différent. La nouvelle attitude a dû stimuler, d'une manière générale, l'intérêt des
philosophes pour les implications épistémologiques de la toute-puissance divine, en particulier pour celles qui concernent les limites de la connaissance
Jean Buridan (né en Picardie, peut-être à Béthune, vers l'an 1300, mort vers 1361) a bien fait face à ces problèmes épistémologiques. En
rendant à César ce qui est à César, et à Dieu ce qui est à Dieu, il a pu déterminer sa propre attitude devant la foi et la théologie. Le philosophe picard a
trouvé les theologizantes sur sa route. La lutte de Buridan contre leur point de vue n'était qu'un corollaire de ses idées optimistes (et bien
fondées) sur les possibilités et la validité du savoir humain." p. 393

"Considering the rich survey Professor Lohr has presented this afternoon of Medieval commentaries on Aristotle's philosophical works
including Metaphysics, there is no point in discussing in general terms the vicissitudes of this Aristotelian work at the Parisian Faculty of Arts. On
top of that, in the lettre d'invitation of the organizers we were asked to say something about our own recent research in the field under discussion.
Therefore I shall confine myself to John Buridan's (c. 1290-c. 1360) commentaries on Metaphysics. Fortunately, Buridan's activity as a commentator on
Metaphysics may to a large degree be regarded as representative of the period. As we learn from Lohr's survey, from the fourteenth century only some
five commentaries on this important Aristotelian writing are extant, quite unlike the thirteenth and fifteenth centuries, from which a considerable amount of
such works have survived. (*)" p. 303

"Properly speaking, nothing is known about our author's life with all due certainty. In recent times, he is commonly identified with the
English logician John Hunt(e)man listed by Emden, who was from York diocese and a master in Oxford still in the 1390's, when Paul of Venice stayed there. He is
reported as a fellow of Oriel College as early as in 1373 and still being there in January 1383. He was Robert Rygge's Junior Proctor of Oxford University in
1382-3, and, like Rygge, he was delated in 1382 for sympathising with the heretic views held by John Wyclif. In 1390, he was Chancelor of Lincoln, and on June
14, 1414, he was appointed Vicar General of the Bishop of Durham. These dates of the John Huntman are all well compatible with his identification with the
author Johannes Venator. It is interesting in this connection that the Vatican manuscript does ascribe the Logica to an English author ("Johannes
Venator doctor anglicus"). Unfortunately, there is no other positive evidence so far for this plausible identification." p. 7.

When visiting Spanish libraries in the Autumn of 1971 I came across a copy of a Sum of Logic in the Biblioteca Capitular Colombina
at Sevilla (cod. 7-3-13). This work attracted my attention because of its clear design and lucid execution. Another copy of this work turned up in the
Biblioteca del Cabildo Metropolitano at Zaragoza (cod. 15-57), under the name "Logica Morelli", and was dated 1476.
The work consists of five parts:
(1) the logic of terms, including the well-known properties of terms, supposition, ampliation, and appellation.
(2) the logic of propositions, including their various "probationes" (in the wake of Richard Billingham, Speculum, and the
widespread adaptations of this work)
(3) the theory of argumentation
(4) the doctine of the predicables and the categories
(5) the doctrine of the so-called "obligations".
This treatise seems to nicely testify to fifteenth-century logical education in Spain. We owe a survey of the contents of this work together
with a description of the two manuscripts to our colleague Joke Spruyt." pp. 209-210-

From the Preface: "In this book I intend to show that the ascription of many shortcomings or obscurities to Aristotle resulted from
persistent misinterpretation of key notions in his work. The idea underlying this study is that commentators have wrongfully attributed anachronistic
perceptions of 'predication', and statement-making in general to Aristotle. In Volume I, what I consider to be the genuine semantics underlying Aristotle's
expositions of his philosophy are culled from the Organon. Determining what the basic components of Aristotle's semantics are is extremely important
for our understanding of his view of the task of logic -- his strategy of argument in particular.
In chapter 1, after some preliminary considerations I argue that when analyzed at deep structure level, Aristotelian statement-making does
not allow for the dyadic 'S is P' formula. An examination of the basic function of 'be' and its cognates in Aristotle's philosophical investigations shows that
in his analysis statement-making is copula-less. Following traditional linguistics I take the 'existential' or hyparctic use of 'be' to be the central one in
Greek (pace Kahn), on the understanding that in Aristotle hyparxis is found not only in the stronger form of 'actual occurrence' but also in a weaker
form of what I term 'connotative (or intensional) be' (1.3-1.6). Since Aristotle's 'semantic behaviour', in spite of his skilful manipulation of the diverse
semantic levels of expressions, is in fact not explicitly organized in a well-thought-out system of formal semantics, I have, in order to fill this void,
formulated some semantic rules of thumb (1.7).
In chapter 2 I provide ample evidence for my exegesis of Aristotle's statement-making, in which the opposition between 'assertible' and
'assertion' is predominant and in which 'is' functions as an assertoric operator rather than as a copula (2.1-2.2). Next, I demonstrate that Aristotle's
doctrine of the categories fits in well with his view of copula-less statement-making, arguing that the ten categories are 'appellations' ('nominations')
rather than sentence predicates featuring in an 'S is P' formation (2.3-2.4). Finally, categorization is assessed in the wider context of Aristotle's general
strategy of argument (2.5-2.7).
In the remaining chapters of the first volume (3-6) I present more evidence for my previous findings concerning Aristotle's 'semantic
behaviour' by enquiring into the role of his semantic views as we find them in the several tracts of the Organon, in particular the Categories De
interpretatione and Posterior Analytics. These tracts are dealt with in extenso, in order to avoid the temptation to quote selectively
to suit my purposes."
———. 2002. Aristotle: Semantics and Ontology. Volume Ii: The Metaphysics, Semantics in Aristotle's Strategy of Argument. Leiden:
From the Preface to the first volume: "The lion's part of volume two (chapters 7-11) is taken up by a discussion of the introductory books of
the Metaphysics (A-E) and a thorough analysis of its central books (Z-H-O). I emphasize the significance of Aristotle's semantic views for his
metaphysical investigations, particularly for his search for the true ousia. By focusing on Aristotle's semantic strategy I hope to offer a clearer
and more coherent view of his philosophical position, in particular in those passages which are often deemed obscure or downright ambiguous.
In chapter 12 1 show that a keen awareness of Aristotle's semantic modus operandi is not merely useful for the interpretation of his
metaphysics, but is equally helpful in gaining a clearer insight into many other areas of the Stagirite's sublunar ontology (such as his teaching about Time
and Prime matter in Physics).
In the Epilogue (chapter 13), the balance is drawn up. The unity of Aristotelian thought is argued for and the basic semantic tools of
localization and categorization are pinpointed as the backbone of Aristotle's strategy of philosophic argument.
My working method is to expound Aristotle's semantic views by presenting a running commentary on the main lines found in the Organon
with the aid of quotation and paraphrase. My findings are first tested (mainly in Volume II) by looking at the way these views are applied in Aristotle's
presentation of his ontology of the sublunar world as set out in the Metaphysics, particularly in the central books (ZHO). As for the remaining works,
I have dealt with them in a rather selective manner, only to illustrate that they display a similar way of philosophizing and a similar strategy of argument.
In the second volume, too, the exposition is in the form of quotation and paraphrase modelled of Aristotle's own comprehensive manner of treating doctrinally
related subjects: he seldom discussed isolated problems in the way modern philosophers in their academic papers, like to deal with special issues tailored to
their own contemporary philosophic interest."

Colloque International De La Fondation Singer Polignac (Paris, 8-12 Juin 1999), edited by Galonnier, Alain, 207-227. Paris: Peeters Publishers.
"There can be no doubt whatsoever about Boethius's exceptional merits for transmitting Aristotle's logic to us. But while 'Aristotelian'
logic is in many respects synonymous with 'Aristotelico-Boethian' logic, the question can be raised whether Aristotle himself was an 'Aristotelian'. To give
just one example: from Łukasiewicz onwards there has been much debate among scholars about the telling differences between traditional syllogistic and that of
the Prior Analytics. (1)
In this paper I intend to deal with two specimens of Boethius's way of commenting upon Aristotle's text. They are found in his discussion of
De interpretatione, chapters 2 and 3, which present Aristotle's views of ónoma and rhema. (2) One concerns the semantics of
indefinite names, the other that of isolated names and verbs." p. 227

Theory of the Syllogism. A logico-philological study of Book A of the Prior Analytics, Dordrecht, 1969.
(2) Rhema properly stands for 'what is said of', including not only our 'verb' but also adjectives, when used in attributive
position. One should realise, however, that 'verb' refers to a word class, rather than a semantic or syntactical category, as rhema does.
"Conclusion. Returning now to Boethius' manner of commenting upon Aristotle's texts, the following points can be made:
 In the wake of Ammonius, (3) Boethius explains [De int.] 16b22-25 on the apophantic level, i.e. in terms of statement-making, instead of
framing significative concepts, i.e. on the onomastic level.
 Whereas in Ammonius' report of the predecessors, Alexander and Porphyry, as well as his own exposition of the issue, there are many clues
to the previous alternative reading and interpretation on the onomastic level, Boethius does not even refrain from cleansing the text (including his
'quotations'), by changing, at any occurrence, 'ens' into 'est'.
 In doing so, Boethius decisively influenced the commentary tradition on account of the purport of De int. 3, 16b19-25. He effectively
contributed to the common verdict on this paragraph in terms of 'a curious medley'.
 As far as the semantics of the indefinite verb (3, 16b14-15) is concerned, Boethius' apparently adhering to the so-called 'Ammonii
recensio' was far less desastrous for the common understanding of Aristotle on this score, and, in effect, merely provided us with some stimulating Medieval
discussions of the semantics of term infinitation.
 Finally by way of speculative surmise, it might be suggested that both the fact that Boethius dealt with the 'Ammonii recognise' without
reading it in his lemma of 16b14-15, as well as his rather ruthlessly interfering in the quotations of the pre-Ammonian sources, should make it more plausible
that Boethius had extensive, but incomplete marginal notes to his Greek text of Aristotle at his disposal, rather than a full copy of Ammonius' commentary (or
those of other Greek commentators).
To comment upon Aristotle's work naturally includes developing his lore. But nothing can ever guarantee that this will happen ad mentem
(3) It is unmistakably plain that in De int. ch. 3, Boethius is strongly influenced by what he read in Ammonius (or in marginal
notes on Ammonius' view).

"Aristotle's doctrine of indefinite names (nouns) was handed down to the Middle Ages together with Boethius' comments and explanations.
Boethius' view of the matter has two characteristic features. For one thing, there is a certain ambiguity on his part concerning the precise semantic value of
such terms; for another, Boethius deviates considerably from Aristotle in that he explicitly assigns the property of 'holding indifferently of existents and
non-existents' not only to the indefinite rhéma (as it is found in Aristotle, De interpr. 3, 16b15) but to the indefinite name (onoma) as
Until the end of the 12th century the logic and grammar (1) of indefinite terms (nouns and verbs) was a much debated issue. Although
assiduously echoing the well-known auctoritates Medieval thinkers did not always go the whole way with their predecessors. For example, Abelard and
Scotus, starting from their own philosophical tenets, more or less inconspicuously corrected some dubious elements in Boethius' interpretation of Aristotle's
doctrine of the indefinite name. Peter Abelard, especially, took great pains to precisely define the meaning of indefinite terms. He focussed his attention on
the proper meaning of indefinite terms rather than on the question whether they are 'holding indifferently of existents and non-existens'. In contrast,
13th-century scholars like Duns Scotus and Radulphus Brito based their discussion of the proper meaning of the indefinite name upon the question 'Utrum
nomen infinitum aliquid ponat' ("Whether an infinite name posits something"), which calls to mind Boethius' claim that indefinite names 'hold
indifferently of existent and non-existents'.
Abelard's discussion of the proper meaning of the indefinite name is also interesting in that it helps us to gain a good understandiiip of
what Boethius had in mind in claiming that the indefinite name 'siginifes an infinite number of things' ('significat infinita'). For, thanks to
Äbelard's expositions, it becomes clear that the phrase 'significare infinita', which, on the face of it, may be taken as referring to the extensional
of the indefinite name, on closer inspection proves to concern its intension, because the controversy between Abelard and Boethius turns out to be about two
different views of the indefinite name's intension rather that about any opposition of intension as against extension." pp. 207-208.

"1. As I have argued for elsewhere, the Greek notion 'ES-' or 'be' as coming to the fore in its several grammatical appearances - the
infinitive einai, the articular participle to on, and the verbal noun ousia - not only refers to what is actually there ('exists') or
actually is the case, but can also represent a form of 'be' that does not, as such, include actual existence, and indeed indicates the general ontic condition
that underlies, and is in fact connoted by, any categorial designations. To Aristotle in particular, each and every noun includes what I have termed
'connotative' or 'intensional' be-ing. (...)" The semantic view that every nominal or verbal sememe by connotation contains the fundamental notion of be-ing is
at the basis of Aristotle's argument against Plato. To Plato, transcendent Being is the fullness of Forms (later called 'plenitude formarum'), whereas
particular forms existing in the outside world are merely as many shares of such-and-such be-ing in virtue of which the outside things share in the
transcendent Source of Beingness. In Aristotle, things are quite different: there is no being-ness other that what is found in particular beings. It is their
immanent forms which are constitutive of their (modes of) be-ing, rather than some putative transcendent Source (on the contrary, as it is worded later on:
'forma dat esse'). By itself, 'be' even is a categorially empty notion The fact that to Aristotle, 'be-ing' is a categorially empty notion by no means implies
that Aristotle should be unaware of the fundamental importance of the notion of be-ing when it comes to metaphysical investigation. It need not come as a
surprise that it is in his "Metaphysics" that the notion of 'be-ingness' (ousia) is the very nucleus of the metaphysical search for the quiddity of things:
this search concerns true 'ousia' or true 'being-ness'. All things considered, despite his obstinately arguing for the (categorial!) emptiness of the notion
'be', Aristotle recognizes the basic sememe of 'be-ing' present in each and every categorial notion, and at the same time he is, to some extent, aware that
there are also some other general ontic notions, which are equally fundamental to metaphysics." pp. 3-4

"This volume contains the first critical edition of Girald Odonis (d. 1349), De intentionibus, in which the author deals with the
multifarious problems around conceptualization with which philosophers and theologians from around 1300 were faced when attempting to bridge the gap between
thought and reality. Girald appears to have been an unyielding defender of the 'realistic' position, holding that our variously articulated concepts
(intentiones) are representative of as many distinctions in Reality. The main target of his severe criticism upon contemporaneous views of the matter
is Hervé de Nédellec, who was the first to write a monograph De intentionibus, which betrays his adherence to a moderate realism. The editor's
extensive study of the intentionality debate of those years focusses on the development of the cognition theory in the period between Thomas Aquinas and Peter
Auriol (d. 1322)."

"Everyone interested in the history of philosophy knows that the problem of the universal has played a predominant role. Ockham may indeed
have tried to highlight the importance of this problem by nullifying its counterpart, the problem of individuation, to the great majority of Medieval thinkers,
however, the problem area surrounding the principle of individuation remained of serious interest. Against the background of the phenomenon of universality as
strictly required for obtaining genuine knowledge, they kept regarding the individuality issue as a source of philosophic and theological perplexity which
could not be underestimated with impunity. The purport of this paper is to evaluate Girald Odonis's treatment of the individuation issue (In II Sent., dist. 6,
q. 4, and, in addition, In III Sent., dist. 1, qq. 1-3) in the context of what others brought forward on the subject, particularly Godfrey of Fontaines and
As Russel Friedman has rightly observed, from the beginnings of 14th century onwards, the Sentences commentary came into its own as
a preferred medium of scholastic theological and philosophical discourse, certainly rivaling in this respect, and often outshining, other vehicles of
theological expression (e. g. Quodlibetal questions, Summae, Biblical commentaries). The Ftanciscan Master, Giraldus Odonis (c. 1280-1349) was among
the numerous scholars who were beginning to use the Sentences commentary as a vehicle for mature thought about a gamut of controversial philosophic as
well as theological issues. Therefore the occurrence of this philosophically hotly debated item in his Sentences commentary cannot come as a
In the sixth Distinctio of the Second Book, Gerald comes (in the fourth question) to speak about the individuation problem, asking
what it is in virtue of which there is a multiplication of individuals within one species. He proposes to deal with this question by firstly summing up a
number of previous or current opinions, then to advance his own position, and thirdly to reply to the ins and outs, including the backgrounds of the rival
positions." pp. 403-404 (notes omitted).

Introduction, critical edition and indexes by L. M. de Rijk.
"The aim of the present edition is to make two texts available which can throw some more light on the role of Aristotle's
Metaphysics in 14th-15th academic teaching. One of them contains part of an early (hitherto unknown) version of John Buridan's Questions on
Metaphysics, the other is a 15th century abbreviation of precisely this early version. Remarkably, both texts belong to the East European tradition of
Buridan's works, which is the more interesting as they testify to the master's earlier activities as a Parisian teacher on the subject of metaphysics. In
particular, they elucidate Buridan's ongoing semantic approach to matters of metaphysics and ontology as well as his attitude to Aristotle's authority."

De formis (together with his De unitate formae substantialis in eodem suppositio).
"The aim of the present edition of Harvey Nedellec's De quattuor materiis is to make a collection of texts available that can throw
some more light upon the ongoing debates around 1300 about some highly controversial issues, including the plurality of forms, the relationship between being
and essence, the significance (or superfluity) of the intelligible species, and the intellect's priority to the will. Harvey's polemic interventions, which are
explicitly directed against the ontological positions held by Henry of Ghent, are the more interesting as they are coloured by a manifest animosity against his
opponent and the Ghentian way of doing philosophy in general. The author's attitude is most prominent in the first tract of the collection presented in the
first volume, De formis. In order to put the impact of this tract into a larger perspective, Harvey's extensive treatise De unitate formae
substantialis in eodem supposito has been added."

"This paper aims to assess medieval terminism, particularly supposition theory, in the development of Aristotelian thought in the Latin West.
The focus is on what the present author considers the gist of Aristotle's strategy of argument, to wit conceptual focalization and categorization. This
argumentative strategy is more interesting as it can be compared to the modern tool known as 'scope distinction'."

De esse et essentia. De materia et forma. A Critical Edition from Selected Manuscripts.
"This second volume presents a critical study of Hervaeus Natalis’s De quattuor materiis, and compares it with the rival systems of
the metaphysics of creation that were upheld by Giles of Rome and Henry of Ghent.
This second volume of Hervaeus Natalis’s polemical work, De quattuor materiis contains his De esse et essentia. In this
work the author criticizes the rival systems of the metaphysics of creation that were upheld by Giles of Rome and Henry of Ghent, and presents an exposition of
his own notion of being. To explain Harvey’s antagonistic attitude to Henry of Ghent and his simultaneous rejection of Giles’s positions (the rigid Aegidian
real distinction between essence and existence in particular) it was necessary to provide a thorough investigation of the ontological positions of both Henry
and Giles. Hence the lion’s part of the Introduction is devoted to these two rivals of Harvey’s.
The selection of the manuscripts used for the present edition of De esse et essentia as well as the ratio edendi,
orthography, punctuation and headings employed, are explained in the General Introduction to volume one, De formis.
This second volume had been finished by the editor, L. M. de Rijk, just before his sudden death on July 30, 2012. The final version has been
read by Joke Spruyt and Olga Weijers.
The third and last volume of the edition of Hervaeus’ work, already well advanced by the editor, will be finished by two of his main
disciples: Henk Braakhuis and Onno Kneepkens. Thus we will have kept our promise, in respect and friendship for our master."
