Aertsen, Jan A. 1985. "The Convertibility of Being and Good in St. Thomas Aquinas." New Scholasticism no. 59:449-470.
"In many medieval thinkers, e.g. Alexander of Hales, Bonaventure, Albert the Great, Thomas Aquinas, the statement can be found: " being and good are convertible " (ens et Comm
convertuntur).(1) That is to say, " being " and " good " are interchangeable terms in predication (converti enim est conversim praedicari).(2) Wherever " being " is predicated of
something, the predicate " good " is involved as well.
That must imply that " good " is here not a concept that adds a real content or a new quality to " being ", as a result of which " being " is restricted. For in that case there
would be no question of convertibility.(3) " Good " is an attribute which pertains to every being, it is a property of being as such, a "mode that is common, and consequent upon every being." In
other words, " good " is coextensive with " being ", it is one of the so-called transcendentie which, since Suarez, are usually referred to as " transcendentals ".

médiévale, 30 août - 4 septembre 1982, Vol. I, edited by Wenin, Christian, 432-439. Louvain-la-Neuve: Peeters.
"Little attention is usually paid to this divine circular motion in the interpretation of Thomas' work, even though Thomas himself says in the prologue to the first book of his
Commentary on the Sententiae that this bringing forth is the «reason» (ratio) of every subsequent process. The circulatio within God is the archetype of the work of
creation. A trinitarian interpretation of Thomas' thought, albeit unusual, finds support in this idea. And his reflections on the originating order of the Trinity could also open up fruitful
perspectives for further thought about (the problematics of) his thought.
In his explanation of the Trinity, Thomas gives a new elaboration of the concept of relation. In the divine circulatio there are relation of primordiality which are
subsistent : «In God relation and essence do differ in being from each other, but are one and the same» (S. Th., I 28, 2). Relation is not an accidental category of substance; being and
relation belong « originally» together.
This idea has remained outside of Thomas' metaphysics of creation. But it is this model of relation,which is philosophically important for a renewed reflection on created being. The
relation of the creature to God is not accidental as Thomas claimed (18), but for the creature to be is to be in relation. At precisely this point a more comprehensive notion of finite being can be
developed. There is the three-foldness in the creature: of subsistent-being, what-being, and act-being. These components agree in esse, which is a being from, through, and to God. In
relationship to the Triune-Origin there is unity.
In man the Trinity is represented in a distinctive way, viz., according to the identical character of activity (secundum eamdem rationem rationis, De potentia, 9,
9). The processes of intellection and volition are found in man. Man, who is a person, is therefore imago Trinitatis. It la in this idea that the «anthropocentrism» of medieval thought most
clearly comes to the fore.
The manner, however, in which man's movement to God is worked out by Thomas, formed a second «crux» in his thinking. Here again we find in his elaboration of the idea of relation,
possibilities for giving his penetrating intuition of the circular motion of egress and return a more integral meaning.
Man is destined to one purpose, viz., communion with God. His drama consists not so much in the natural inability to close the circle through knowing, as in the aversion from his
own essentially relational mode of existence. The circular motion thereby comes to stand in a concrete salvation history. This moreover offers the possibility of doing justice to the internal
coherence of the structure of the Summa Theologiae. In the prologue to bk. 1, 2, Thomas indicates this design: the first part deals with God, and «the procession of all creatures from Him»;
the second with the movement of the rational creature toward Him; and the third with Christ who as man is the way (via) of our tending to God. The second person of the Trinity, the Word,
became flesh in order to show mankind the way (back) to its Origin. True human-being is possible only by God's grace.
In summary: the new perspective which Thomas' reflection on the faith mystery of the divine process opens up, is philosophizing oriented to the perfection of being-itself in being
toward something else." (pp. 438-439)

"Arvin Vos has written an excellent paper on Thomas Aquinas and the classical heritage. His paper shows admiration for and affinity with Aquinas's achievement. I share this
admiration; Aquinas is a great thinker. Now it is a mark of great thinkers that the content of their thought is so full and rich that one can put emphasis on different aspects. And this is what I
intend to do in my response by making some comments and raising some questions. My reflections, stressing a number of underlying ideas, are primarily meant as a supplement to what has been said.
In order to present my remarks in a systematic and coherent way, I take as a starting point a statement of Aristotle which I will develop in four steps, more or less related to the
main parts of Vos's paper: (1) the background of the thirteenth century; (2) Thomas's attitude towards Aristotle; (3) the relationship between faith and reason; and (4) the conclusion concerning the
question whether the classical heritage can be integrated in the Christian position." (p. 83)

———. 1991. "The Medieval Doctrine of the Transcendentals. The Current State of Research." Bulletin de Philosophie Médiévale no. 33:130-147.
"An important, new development in medieval philosophy was the constitution of the doctrine of the transcendentals (DT) in the thirteenth century. The term « transcendental » - the
medievals themselves speak of transcendens -- suggests a kind of surpassing. What is transcended are the special modes of being that Aristotle called the « categories », in the sense that
the transcendentals are not restricted to one determinate category. « Being » and its « concomitant conditions », such as « one », « true » and « good », « go through (circumeunt) all the
categories » (to use an expression of Thomas Aquinas). DT is thus concerned with those fundamental philosophical concepts which express universal features of reality.
The doctrine played a prominent role in later medieval thought. The study of it is essential for our understanding of philosophy in this period, since, according to J.B. Lotz, [«
Zur Konstitution der transzendentalen Bestimmungen des Seins nach Thomas von Aquin », in P. Wilpert(ed.), Die Metaphysik im Mittelalter (Miscellanea Mediaevalia, Vol. 2). Berlin 1963, pp.
334-340] p. 334), DT is « the core of Scholastic ontology and metaphysics ». Remarkably, however, research on this doctrine has hitherto been rather limited. The observation, made by the French
scholar S. Breton [« L'idée de transcendental et la genèse des transcendentaux chez Saint Thomas d'Aquin » in Saint Thomas d'Aquin aujourd'hui. Paris 1963, pp. 45-74] p. 45) in 1963, that DT
is « classic and yet poorly known », still holds. An example of its neglect is the Cambridge History of Later Medieval Philosophy (ed. N. Kretzmann, 1982) that contains only one brief
reference (p. 493, to Ockham). In this contribution I want to take stock of the current state of research on DT, to assemble and discuss the relevant literature, to indicate certain lacunas, and to
make some suggestions for further research." (p. 130).
———. 1991. "Good as Transcendental and the Transcendence of the Good." In Being and Goodness, edited by MacDonald, Scott, 56-73. Ithaca: Cornell University Press.
In ST Ia.6.4 ("Whether all things are good by the divine goodness?") Thomas concludes that the Platonic view appears to be unreasonable in affirming that there are separate
forms of natural things subsisting of themselves; still, it is absolutely true that there is something first that is essentially being and essentially good which we call God. Hence, everything can be
called 'good' and 'being,' insofar as it participates in the first being, which is essentially good. To this conclusion Thomas still adds, however, an important remark. That every being is good
through an external cause by no means excludes each things being called through a goodness that is formally its own goodness. "And so of all things," Thomas ends, "there is one goodness, and yet many
This text can serve as a summary of our analysis, which is focused on the relation between the good as transcendental and the transcendence of the Good. I want to emphasize four
points of philosophical importance in Thomas's reflection on the good.
First, Thomas really understands the good transcendentally by establishing an intrinsic connection between being and goodness. To be is the actuality of everything and thereby a
good proper to each thing. Things are called good in virtue of an inner goodness. It is characteristic of finite things that although being and good are convertible, there is in them nonetheless a
nonidentity between being absolutely and good absolutely.
Second, because the good is transcendental, Thomas applies to it the predication essentially or by participation. This predication expresses the transcendence of the divine goodness
and the creaturely character of the goodness of other things. That which is in any way good must be reduced to what is good by its essence as to its origin. That things are good through an intrinsic
goodness is not incompatible with their dependence on that which is the good itself.
Third, from a historical point of view, Thomas effects a kind of synthesis between the Aristotelian way of thought and Aristotle's conception of the good, on the one hand -- the
good is something common and the essential forms of things are inherent in them -- and the Platonic way of thought and Plato's conception of the good, on the other hand -- the Form of the Good is
"separate" from particular goods.
Fourth, Thomas effects a synthesis in still another respect. Characteristic of Boethius's position, according to MacDonald,(29) is the creation approach to explaining the relation
between being and goodness. Aristotle's view, in contrast, exemplifies what might be called the nature approach. This approach explains what it is for a thing to be good by referring to the nature of
the thing. "The historical significance of DH [Boethius's De Hebdomadibus] MacDonald says, "consists largely in its offering an interesting account of the nature of goodness which
is possibly incompatible ... with the sort of account medieval philosophers found in Aristotle." Thomas's reflection on the claim that all things are good and on question how they
are good can be regarded as a philosophically original synthesis of the nature approach and the creation approach."(30) The nature approach explains the intrinsic goodness of things, for 'nature'
says what beings are in themselves; it always refers to an intrinsic principle. Now, it is Thomas's transcendentality claim that everything is good, insofar as it is. Things are good (in a
certain respect) in virtue of their own being. So all things owe their being good to their nature. The creation approach explains that everything is called 'good' through an external cause, for
'creature' says being-related to the Origin of things. Creation expresses that things received their being and goodness from another. Their goodness consists in their relation to the
transcendent good, that is, in their participation in what is goodness itself." (pp. 72-73)

"Aquinas presents his most complete exposition of the transcendentals in De veritate 1, 1, that deals with the question "What is truth?". The thesis of this paper is that
the question of truth is essential for the understanding of his doctrine of the transcendentals.
The first part of the paper (sections 1--4) analyzes Thomas's conception of truth. Two approaches to truth can be found in his work. The first approach, based on Aristotle's claim
that "truth is not in things but in the mind", leads to the idea that the proper place of truth is in the intellect. The second approach is ontological: Thomas also acknowledges that there is truth
in every being. The famous definition of truth as "adequation of thing and intellect" enables him to integrate the two approaches. Truth is a relation between two terms, both of which can be called
"true" because both are essential for the conformity between thing and intellect.
The second part of the paper (sections 5--7) deals with the manner in which Thomas gives truth a place in the doctrine of the transcendentals, and shows that his conception of truth
leads to important innovations in this doctrine: the introduction of relational transcendentals and the correlation between spirit and being. If "truth" is transcendental, it must be convertible with
"being". Sect. 6 discusses objections that Thomas advances himself to this convertibility.
Sect. 7 deals with a difficulty in his account of truth as a relational transcendental. Ontological truth expresses a relation to an intellect but the relation to the human
intellect is accidental for the truth of things. Essential for their truth can only be a practical intellect that causes things. In this way, Thomas argues, the divine intellect relates to all
things." (p. 159)

edited by Bos, Egbert Peter and Meijer, Pieter A., 120-140. Leiden: Brill.
"In this contribution I would like to investigate whether and in which way the opposition between ontology and henology took shape in medieval thinkers and was a subject of
discussion. I will focus my inquiry on three Dominicans of different generations, namely, Thomas Aquinas, Master Eckhart and Berthold of Moosburg. The last one is the least well known of the three.
Yet I want to begin with him, since we find in his work not only a justification but also a philosophical deepening of our question." (p. 122)
In my paper I first presented a medieval version of the question: "Metaphysics of Being or philosophy of the One?" - namely, the interpretation of Berthold of Moosburg. In his
commentary on Proclus [*] he traces the opposition between ontology and henology to the different structures of thought associated with Aristotelianism and Platonism, which we have indicated with the
keywords "transcendentality" and "transcendence" of the first. I then proceeded to use Berthold's model to elucidate the thought of Thomas Aquinas and Master Eckhart. To this analysis I would add
three concluding observations.
First, we can ascertain that for Thomas and Eckhart the transcendental and transcendent approaches do not form an absolute opposition. Thomas posits a causal relation between God
and the maxime communia. Transcendentals are to be traced to God as their cause. Eckhart identifies. God and the transcendentia. That which is most general is God.
Secondly, both in Thomas and in Eckhart the doctrine of transcendentals is found to have an integrating function. That is notable, because Berthold regards this doctrine as typical
of the Aristotelian position. Now this theory certainly contains anti-Platonic elements, as we observed in Thomas, such as the emphasis on predicative generalness. But transcendentals have yet
another aspect, which Berthold does not mention, an aspect which played an essential role in the development of the doctrine. Generally, the Summa de bono of Philip the Chancellor, written
about 1230, is regarded as the first treatise on transcendentals. In the prologue of this work Philip observes that "being," "one," "true" and "good" are not only that which is most common but are
sometimes also "appropriated," that is, treated as "proper" to something. For in Scripture these names are attributed pre-eminently to God, they are also divine names. (90) The attention given this
second kind of naming is undoubtedly influenced by pseudo-Dionysius, who functions in Berthold as an eminent witness for the Platonic view. Thus we see that in the context of the doctrine of
transcendentia themselves the question must arise concerning the relation between the most general which goes through all categories, and the divine which surpasses all categories.
Thirdly, the medieval doctrine of transcendentals is pluriform. The solutions of Thomas and Eckhart diverge. Philosophically more important, however, is that in which they agree.
Characteristic of philosophy is a transcending movement. It surpasses the concrete things of experience in quest of a first, from which reality can be understood. The answer to the question of what
this first is can be sought in different directions. Berthold sketches two options: the first is the most general, which is the precondition for man's intellectual knowledge; or the first is the
cause of the being of things but is not itself of the nature of the caused. Thomas and Eckhart represent a type of philosophical thought in which the two options in question are connected. That is
their contribution to the debate about what philosophy should be: ontology or henology." (pp. 139-140)

A revised version of this study form the Chapter Three of Medieval Philosophy as Transcendental Thought. From Philip the Chancellor (ca. 1225) to Francisco Suárez (2012),
"Our comparative inquiry does not allow any other conclusion than that Philip the Chancellor, in the introductory questions of his Summa de bono, really presents something
new. His intention of going back into the "ground of thought" by reducing our understanding of questions to the communissima results in the earliest systematic formulation of a doctrine of
the transcendentals. The doctrine is introduced as the philosophical answer to the dualism of Manichaeism. For the first time, Philip brings together four basic notions, "being", "one", "true", and
"good", and investigates their mutual relations. But his account bears the marks of a first draft; it is rather terse and sometimes little explicit.
Viewed from a historical perspective, his doctrine has an atypical aspect, insofar as it is centered in a metaphysics of the good. The context of the doctrine generally is a
conception of metaphysics, in which "being" is the proper subject of this science. Philip recognizes that ens is the first concept, but he does not say much about it. His interest concerns
"the good", a notion that is richer than (habundat) "being". Two elements of Philip's doctrine were especially directive for subsequent discussions of the transcendentals. The first is his
view of the twofold relation between the communissima: there exists a real identity between them -- they are convertible according to their supposits --, but they differ according to their
concepts. The other element concerns the order of the most common notions, which is based on the notion of "indivision". It is somewhat paradoxical that Philip does not deal separately with
unum, whereas the ratio of "one" determines his understanding of bonum and verum.
The Summa de bono was attentively read and frequently used, especially in the Franciscan milieu. The influence of Philip's account of the communissima is manifest
in two works that were composed about twenty years after his Summa, namely, in the Franciscan Summa theologica attributed to Alexander of Hales, and in De bono, an early
writing of the Dominican Albert the Great." (pp. 132-133)

"From the account of the relation between res and ens it is possible to draw a number of conclusions pertinent to Henry's way of thought and his point of
I. The first conclusion is that it is incorrect to say that in his thought there is an insoluble tension between the primacy of being and that of thing. Henry describes the relation
between the first concept, that of "thing" in the most general sense, and the second concept, that of "being," as a relation of foundation. "Something cannot have the character of being unless it
first has the ratio of thing in the sense of reor, reris, in which the ratio of that being is founded (fundatur). (46)
2. The firstness of res is not an a priori condition of knowledge, that is, a "transcendental form" in the Kantian sense. It can be an idle concept, such as an imaginary
thing. The firstness is related, as appeared from the discussion of the seventh Quodlibet, to the way in which the human intellect is "moved" by reality. The relation of foundation between
res and ens is worked out by Henry in two respects, from the angle of the theory of science and ontologically.
3. From the angle of the theory of science, the relation is that between the precognition of a quiddity and intellectual knowledge of it. At the first level, res in the
sense of reor, reris is the most general concept, the communissimum of the seventh Quodlibet. At the second level, "being" is the first and most general concept. Henry's
statement that ens is the first that is scientifically known (scita) must be understood in this precise sense.
In ontological respect, the relation between the first and the second concept is the relation between the still undetermined thing and the thing that is determined by its essence.
The quidditative being however is not determined to this or that thing, to creator or creature, to substance or accident. It is understood, Henry states, under the aspect of being that is the subject
of metaphysics. (47) Not the first mode of "thing" but the second mode is the point of departure of metaphysics.
The level of quidditative being is the level of the transcendentals. Henry's identification of res, ratitudo with ens is the answer to the question (see section 3,
above) why res is not named in Henry's account of the transcendentals. It is the concept that lies at the basis of his doctrine of being and of the most general intentiones. In
comparison to his predecessors, the novelty of Henry's doctrine is the central place he attributes to Avicenna's notion of "thing." That res, ratitudo lies at the basis of Henry's doctrine
explains the fact that he, otherwise than in the tradition, understands truth as a real relation to the exemplar.
Another distinctive feature of Henry's doctrine of the transcendentals is its being preceded by a more general concept, the cognition of "thing" in the broadest sense. For the
clarification of this relation one may utilize a distinction that emerged in post-medieval philosophy. In a study of the concept of res, Ludger Oeing-Hanhoff has called attention to the fact
that in the seventeenth century transcendental concepts were opposed to "super-transcendental" concepts, which are said not only of real but also of fictitious beings. Examples of these
super-transcendental concepts are cogitabile and opinabile.(48) Henry's notion of res may be regarded as an anticipation of such concepts." (pp. 17-18).

"In the prologue of his commentary on the Metaphysics, Duns Scotus explains the name 'metaphysics' as transcendens scientia, that is, the science that is concerned
with the transcendentia.(1) This explanation is indicative of the prominent place Scotus ascribes to the doctrine of the transcendentals, which was formulated for the first time in the
Summa de bono of Philip the Chancellor that is datable about 1225. The connection between the object of first philosophy and the transcendentals is not in itself new, although the identity
posed by Scotus is more radical than in his predecessors.(2) Yet it is no exaggeration to say that Scotus's philosophy marks a new phase in the history of the doctrine of the
Scotus understands the concept 'transcendental' differently than his predecessors did. To thinkers of the thirteenth century, transcendental properties are communissima.
'Being, 'one,'true' and 'good' 'transcend' the Aristotelian categories because they are not limited to one of them but are common to all things. According to Scotus, however, it is not necessary that
a transcendental as transcendental be predicated of every being; it is not essential to the concept transcendens that it has many inferiors. In his Ordinatio he determines the
concept negatively: 'what is not contained under any genus' or 'what remains indifferent to finite and infinite'. (3) This definition makes possible a vast extension of the transcendental domain; the
most important innovation is formed by the so-called disjunctive transcendentals, which are convertible with being, not separately but as pairs.
The fact that the transcendental properties are not necessarily identical with the communissima is, I suspect, the reason why the expression transcendentia, which
occurs only sporadically in thinkers like Albert the Great, Thomas Aquinas and Henry of Ghent, gains the upperhand in Scotism and becomes the usual term.
About Scotus's doctrine of the transcendentals, in contrast to that of other medieval thinkers, we are well informed by Allan B. Wolter's pioneering study, The Transcendentals
and Their Function in the Metaphysics of Duns Scotus (1946). Yet there are aspects of his doctrine that have thus far received little attention in scholarly literature. One of them is Scotus's
treatment of the transcendentals 'one, 'true' and 'good,' which as such are convertible with being. In my contribution I want to show that with respect to the traditional transcendentals, too, Scotus
breaks new ground and approaches critically the views of his thirteenth-century predecessors. Because he discusses most extensively the relation between being and one, I foals on this discussion."

"In 1597 Francisco Suarez published his Disputationes Metaphysicae, a work that had an incredible influence on seventeenth century philosophy. The most salient feature of
his metaphysics is the central position of the transcendentia or transcendentalia (Suarez uses these terms as synonyms) : Disp. 2-11 deal with being, unity, truth and goodness. In
comparison with Aristotle's conception of a science of being, metaphysics had acquired a « transcendental » character. As Suarez knew very well, this transformation had taken place in the Middle

"In the study of medieval philosophy it is customary to speak of the doctrine of the « transcendentals » (1). We have to realize, however, that this term comes from the vocabulary
of modern philosophy. The medieval authors themselves speak of transcendentia. What is the significance of this fact ? What is in those names ? By way of introduction, we consider the two
terms, « transcendent » and « transcendental », more closely in order to make clear that the interference of the conceptual language of modem philosophy with that of medieval philosophy is not
coincidental. The difference in terminology points to a doctrinal evolution. (p. 241)
"By way of conclusion, let me sum up the main results of our inquiry into the genealogy of the term transcendentia (in the sense of transcendentals »).
(i) The first philosophical account of a doctrine of the transcendentals is presented in Philip the Chancellor's Summa de bono. This work did not use the term
transcendentia, but later in the thirteenth century Roland of Cremona, Albert the Great and Thomas Aquinas applied the term to a systematic doctrine of the communissima. The origin
of the doctrine is not the Platonic-Augustinian idea of « transcensus », but rather the Avicennian tradition of primary notions.
(ii) The term transcendentia already existed before the emergence of a systematic doctrine. Albert the Great's commentaries and some texts from the Logica
modernorum strongly suggest that the term originates in logical discussions, focussing on the distinctive nature of certain (« transcendental ») terms." (p. 255)

"The history of res as a transcendental term is an intriguing one: it could be described in terms of a success-story: from "nothing" to "king". In the first account of a
doctrine of the transcendentals, the Summa de bono written by Philip the Chancellor ca. 1225-28, res is not mentioned at all. In the prologue Philip states that « most common
(communissima) are these : ens, unum, verum, bonum », whose mutual relations he investigates in the next questions (1). Res is also absent in the expositions by Alexander
of Hales, Bonaventure and Albert the Great: they restrict the number of transcendentals to the four that Philip had listed in his Summa (2).
Thirty years after Philip, however, the picture changes. In his account of the transcendentals in De veritate q. 1, a. 1 -- the most extensive one in the thirteenth century
--, Thomas Aquinas incorporated res into the doctrine. He distinguishes six transcendentia, in the order ens, res, unum, aliquid, verum and bonum (3). Yet the role
of the new transcendental res in Thomas and the Thomistic tradition in general remains somewhat marginal. A good illustration offers a treatise from the 14th century, the Tractatus de
sex transcendentibus, composed by Franciscus de Prato (who was lector in Perugia from 1343-45). The treatise is an attempt to systematize the doctrine on the basis of Thomas's teachings.
Contrary to the order in De veritate, res holds the last place in this work, and its treatment is substantially briefer than those of the traditional transcendentals (4).
But in the generation after Thomas Aquinas, res started, as we shall see a splendid career. A notable reaction against Thomas's doctrine is Lorenzo Valla's philosophical
mainwork Dialecticae disputationes (first version 1439) (5) In these disputations, Valla critically inquires into the basic notions of traditional philosophy, starting with the six
primordial prin ciples (primordia) which the Aristotelians called transcendentia. They regarded these principles as the "princes of princes" or the "kings", but according to Valla a
plurality of firsts is impossible ; only the monarchy is good. He will therefore investigate which among the six is the true rex imperator, that is, the most comprehensive
(capacissima) notion (6).
Valla's conclusion is that only res can claim this title. It is evident unum is to be understood as "one res", aliquid as "another res", etc. But
how about the notion ens, to which the Aristotelians give a place honour? In Valla's view, the term does not have a universal force of its own, but its force is wholly borrowed from another,
namely from res (7) His arguments are marked by the (humanistic) linguistic turn; they are mainly philological. Ens is a participle that is to be resolved into a relative pronoun and a verb
: id quod est. Id is to be resolved into ea res, so that finally ens can be reduced to ea res que est (8). When we say, for instance "the stone is being"
(lapis est ens), the expression means "the stone is thing (res) which is". But does such a formula make any sense, when simpler and clearer to say "the stone is a res"? The
words "that which is" cannot mean that the stone is "the thing that is", because only God "is" in the proper sense (Exodus 3,14). When therefore it is said of something else than God that it
is "being" (ens), one uses an inappropriate way of expression (9).
The dignity of a transcendental was given only to res (10). To illustrate its position, Valla alludes to a story, reported by Herodotus in his Historiae (III, 86),
a work that Valla translated into Latin. Six Persians contested the empire, but when Darius managed to become the king of the Persians, the other five descended from their horses and rendered hommage
to the king. Similarly the other five transcendentals descend in order to honor res (11).
With respect to the remarkable history of "thing" I want to raise three questions: How did res come into philosophy, why did it enter philosophy and what did it bring about
in philosophy, for our understanding of "reality" (12)?" (pp. 139-141 notes renumbered)

Communis II, n. s., 50-54. Vatican City: Pontifica Academia Sncti Thomae Aquinatis.
"When I was invited to comment upon the theme of the section -'Truth in Thomas Aquinas' - I pondered on the best way of meeting the request. I asked myself: What is most important
in his conception of truth? The following comments are designed to be an answer to that question and are based on Thomas's remarks in De veritate. As such, my answer does not pretend to be
definitive, but is based on personal reflections that are indebted to on-going discussions in the German academic world to which I belong. That said, I would hope that my comments possess some
general relevance to other students of Thomas. It is my view, that the salience of Thomas's view of truth can be appreciated by means of highlighting four substantive points.
1. First and foremost we should attend to Thomas's approach to the question quid sit veritas.
2. Having considered the transcendentality of the truth, Thomas then solicits an answer to the question as to what it is.
3. There is truth in things; 'truth' is also predicated of the intellect.
What, then, is the primary 'locus' of truth: the thing or the intellect?
In his reply to this question ( De veritate q. 1, a. 2) Thomas advances the idea of the analogy of the true; this predicate is said of many things according to an
order of priority and posteriority, that is, in relation to one (thing) that possesses the ratio of the predicate primarily. The classical application
of the doctrine of analogy concerns the term 'being'. The novelty of Thomas's thinking here is to be seens in his application of the analogy to the predicate 'true', in order to
determine the relation between the truth of being and the truth of the intellect.
4. At De veritate 1,4 Thomas poses the question that dominates the first systematic account of truth in the history of philosophy, Anselm of Canterbury's work De
veritate: 'Is there only one truth by which all things are true?' Anselm had answered this question affirmatively; there is only one truth in the proper sense ( proprie), the divine
truth. Thomas's reply is more differentiated: truth is properly found in the human or divine intellect; primarily in the divine intellect; secondarily in the human intellect. A human truth, too, is
truth in the proper sense.
The power of truth manifests itself in its claim of having absolute force; it holds without respect of persons. Thomas gives a remarkable example of that in his Commentary on
the Book Job. He interprets the dispute between Job and God after the model of a medieval disputation. But Thomas wonders whether such a disputation is appropriate, since God is far superior to
any human being. Truth does not change because of the difference of persons.
When somebody speaks the truth, he cannot therefore be defeated, irrespective of the person, with whom he disputes ( cum aliquis veritatem loquitur, vinci non potest cum
quocumque disputat). (8)
In summary, four ideas are most important in Thomas's conception of truth: the transcendental character of truth; its relationality (truth as adequation); the primary 'locus' of
truth is the mind; and a human truth also is a truth in the proper sense. Seen together, they reflect the novelty of his philosophical thought and its relevance." (pp. 50-54)

"This essay examines Aquinas's analysis of the human desire to know, which plays a central role in his thought. (I.) This analysis confronts him with the Aristotelian tradition:
thus, the desire for knowledge is a "natural" desire. (II.) It also confronts him with the Augustinian tradition, which deplores a non-virtuous desire in human beings that is called "curiosity."
(III.) Aquinas connects the natural desire with the Neoplatonic circle motif: principle and end are identical. The final end of the desire to know is the knowledge of God. (IV.) Aquinas also connects
the end of the natural desire to know with Christian eschatology, teaching that man's ultimate end is the visio Dei. This end, however, is "supernatural." (V.) Duns Scotus severely criticizes central
aspects of Aquinas's account. (VI.) As a rejoinder to Scotus's objections, we finally consider Aquinas's view on the proper object of the human intellect."

that is is good. The basic text used is a Quodlibet disputed by the Parisian master Gerard of Bologna at the beginning of the fourteenth century, in which he discusses various determinations
of the nature ( ratio) of the good. This discussion reveals the difficulties to which the metaphysics of the good can lead: is it really the case that every being is good?"

philosophical dictionary of our time, the Historisches Worterbuch der Philosophie, which appeared in 13 volumes from 1971-2007. The vocable was suggested by French scholars two decades ago
in their analysis of the genealogy of Western metaphysics and has since then found acceptance. « Tinology » is meant to characterize an alternative for the traditional ontological model of
metaphysics. Influential was an observation made by Jean-Francois Courtine at the end of his monumental study on the metaphysics of Francis Suarez : « En rigueur de termes, l'ontologie
classique-moderne devrait donc plutot être caracterisée comme une 'tinologie' »(1). The emergence of this neologism and its historical place is the first thing that calls for attention." (p. 729)
