"Although Abelard arrived at a view of "ens" nearer to Aristotle's than his sources would suggest, unlike Thirteenth-century thinkers he did
not work out a view of transcendentals in terms of "ens", its attributes and their convertibility. He did, however, regard unity (though not goodness or truth)
as an attribute of everything. At first, Abelard suggested that unity, being inseparable, could not be an accident according to Porphyry's definition (' that
which can come and leave a subject without the subject being corrupted') either it is some type of form not classified by Porphyry, or not a form at all. In
his later logical work, Abelard argued differently. Unity, he said, is an accidental form, but Porphyry's definition of an accident must be understood
negatively, not as asserting something about what could happen in reality (since the form of unity could never leave its subject) but rather something about an
absence of connection: were it, per impossible, to occur, the loss by a subject of its form of unity would not lead to the loss of its specific or generic

"When, in 1966, Father Chenu published Les platonismes au XII siècle, twelfth-century Platonism had already been a topic of
scholarly interest for nearly a century. (1) Chenu's novelty lay in his plural: not «Platonism» but «Platonisms». He distinguished a strand going back to
Augustine, another deriving from the Timaeus and Boethius, one linked to pseudo-Dionysius and another to Arab writers. Chenu's is a useful analytical
method which allows the scholar to avoid broad, oversimplifying labels whilst continuing to see the history of medieval philosophy in the neat terms of
interrelated and interacting traditions. No doubt it could be fruitfully applied to Abelard -- but that is not my intention here. The Platonisms I shall be
discussing are not those of the historian, but Abelard' s own: some of the diverse ways in which he used a notion of Plato and Platonic teaching to formulate,
structure and convey his own thought (2). At the end of this paper, I shall return to the question of method, and ask what my procedure has to offer by
contrast with other ways of discussing Platon- or any other -ism."

"My article surveys philosophical discussions of Abelard over the last twenty years. Although Abelard has been a well-known figure for
centuries, his most important logical works were published only in the twentieth century and, so I argue, the rediscovery of him as an important philosopher is
recent and continuing. I concentrate especially on work that shows Abelard as the re-discoverer of propositional logic (Chris Martin); as a subtle explorer of
problems about modality (Simo Knuuttila, Herbert Weidemann) and semantics (Klaus Jacobi); as a metaphysician before the reception of Aristotle's Metaphysics
(Peter King); and as an ethical thinker who echoes the Stoics (Calvin Normore) and anticipates Kant (Peter King)."

"It was Christopher Martin who, in 1992, first made the link between Abelard's views on accidents and differentiae and what are
usually called, in contemporary analytical ontology, 'tropes'. Myself apart, Alain de Libera is the only writer I know who has taken serious notice of this
idea, discussing it both on its own, and in the wider context of truth-makers and empty reference.(1) De Libera does not think that Abelard can illuminatingly
be described as a trope-theorist. I still disagree, and although our disagreement is based on matters of detail, it may illustrate, as I suggest in the
conclusion, a wider difference in approach."

"Mediaeval logicians inherited from Boethius an account of conditional propositions and the syllogisms which may be constructed using them.
In the following paper it is shown that there are considerable difficulties with Boethius' account which arise from his failure to understand the nature of
compound propositions and in particular to provide for their negation. Boethius suggests that there are two different conditions which may be imposed for the
truth of a conditional proposition but he really gives no adequate account of how such propositions may be obtained. The true greatness of Peter Abaelard as a
philosophical logician is revealed in what he is able to do with the material which he found in Boethius. It is shown that he developed a precise theory of
conditionals giving an account of how true conditionals may be obtained and principles which may be used to reject others as false. Unlike Boethius Abaelard
properly appreciates that conjunctions must be treated as logical units. Even he, however, falls victim to difficulties which arise when this connective is
brought into contact with negation and the conditions which he lays down for the truth of a conditional."

Geschichte Der Metaphysik, edited by Buchheim, Thomas, Henri, Kneepkens Corneille and Lorenz, Kuno, 97-125. Stuttgart: Frommann-Holzboog.
"In his monumental study of William of Sherwood's modal theory Klaus Jacobi (2) surveys the treatment of modality by philosophers in the
preceding century and shows that their concern was for the most part to calculate the logical relations between the various forms of modal proposition which
they recognised. Although theology demanded that they take an interest in the nature of divine power, without the Physics and Metaphysics, to
prompt them, twelfth century philosophers generally had little to say on the relationship of modal propositions and their structures to the various sources of
modal claims, to claims, for example, about the nature of potentiality, physical causation, or action.(3) Some progress was made, however, and in the present
paper I will consider the contribution of Peter Abaelard to the development of theories of modality and the curious attitude of one of his followers to his
work on modal logic.
Although Abaelard had no access to the Physics or Metaphysics and precious little, if any, to the Prior
Analytics,(4) he did find in the Categories and De Interpretatione texts which posed interpretive problems whose solution demanded that
he discuss the nature of possibility and necessity. What follows is for the most part an examination of certain points made by Abaelard in his discussion of
these problems. It is divided into two parts.
In the first part of the paper I propose an account of Abaelard's theory of possibility and its application both to creatures and to God.(5)
Abaelard's claims about divine power are rather well known and I mention them only very briefly at the end. His treatment of creaturely potentiality in
commenting on various claims made by Aristotle in the Categories has, on the other hand, barely been noticed and my concern in the first part of the
paper is to thus set them out in some detail.
The failure to take into account the full range of Abaelard's thinking about potentiality has led to some very misleading claims about his
views on possibility. What my investigation shows is that Abaelard employs three different but related notions of potentiality. The first is the potentiality
that an individual has for future action and it is constrained by its species nature, its particular constitution, and its present circumstances. The second
and third are both introduced to explain how we may legitimately say, as authority requires, that an amputee is bipedal. They are different but both reduce all
unqualified possibility to potentiality and all potentiality to compatibility with species nature. The unqualified possibilities open for an individual
creature of a given natural kind are thus for anything which is not incompatible with its species nature.
In the second part of the paper I first examine the account of modal propositions that Abaelard insists upon in discussing chapter 12 of
De Interpretatione. I show that this account of the semantics of such propositions is completely in agreement with his treatment of the source of
modal properties in natures. In his treatment of modal propositions Abaelard famously distinguishes between two different interpretations of propositions such
as 'S is possibly P'. A personal, or 'de re' reading, in which S is said to possess a power to be P, and an
impersonal, or 'de sensu' reading in which 'S's being P' is claimed to be possible where the nominal phrase is held to refer to a
proposition, propositional content, or some other kind of entity. Abaelard argues that only the de re reading yields a modal claim and that nominal
modes are to be resolved into the corresponding adverbial modes. The truth conditions of modal propositions are thus always, according to Abaelard, ultimately
to be given in terms of what is compatible and what is not with the specific nature of the subject of the de re reading of them.
Information about the fate of Abaelard's theories and the views of his followers is unfortunately very limited and it is pleasant to be able
to add here to our knowledge. The texts that we have on divine and creaturely power agree with Abaelard's teaching in reducing unqualified potentiality to
compatibility with species nature. In the concluding part of my paper, however, I show that the author of the Summa Dialectice Artis attributed to
William of Lucca, otherwise an extremely devoted follower of Abaelard in logic, explicitly rejects his master's de re account of modality in favour of
the alternative de sensu reading which Abaelard had gone to great lengths to refute. The Summa thus leaves us with a considerable puzzle
about the commitment of Abaelard's followers in logic to his theory of modality. As compensation for this, we will see that the Summa also provides us
with a solution to a small puzzle raised by Jacobi and Knuuttila concerning Abaelard's views on the logical relations between quantified modal propositions."

(3) The outstanding exception is St. Anselm's discussion of the logic of action sentences in the Lambeth Fragments printed in R. W. Southern
and F. S. Schmitt, Memorials of St. Anselm, London 1969, 333-354.
(4) Cf. Dialectica, Introduction,XIII-XIX. The evidence that Abaelard had direct access to the Prior Analytics is extremely
slight. The Dialectica contains what appear to be two quotations from the Prior Analytics, the definition of the syllogism from An.
Pr. I 1, 24b 18-22 at Dialectica, 232.5-8 and the distinction between perfect and imperfect syllogisms from An. Pr. I 1, 24b 22-25 at
Dialectica, 233.36-234.3. In the discussion following the definition of the syllogism, however, Abaelard refers not to the definition which he
apparently quotes from Aristotle but rather to the definition given by Boethius in De Syllogismo Categorico II (PL 64, 821A 7 - 822C 12).
(5) Hermann Weidemann, 'Zur Semantik der Modalbegriffe bei Peter Abaelard', in: Medioevo 7 (1981), 1-40, argues that Abaelard thinks
of possibility in this way but he does so very much the hard way by attempting to show that Abaelard's remarks on temporally determined modal sentences
him to it. Here I take the very much easier course of pointing out Abaelard's explicit statement of the theory of synchronous possibility in
terms of alternative world histories.

"A great deal of Peter Abelard's writing is concerned with what he regarded as logic, but which we would now classify as ontology or
philosophical semantics. Following Cicero and Boethius, Abelard holds that properly speaking the study of logic has to do with the discovery and evaluation of
arguments (LI Isag. 3.10). A necessary preliminary for this is an examination of the issues dealt with by Porphyry in the Isagoge and by
Aristotle in the Categories, and De interpretatione (LI Cat. 113.26-114.30). In the present chapter, however, I will ignore most of
this material and concentrate on the central issue of logical theory both for Abelard and for us, that is, on the nature of the relation of consequence, or
following. Even with this limitation there is a great deal of ground to cover. Abelard sets out his theory of entailment and argument in two very extended and
dense discussions both of which have suffered considerable textual corruption. The treatment of topics and hypothetical syllogisms in the Dialectica,
is apparently the earlier. The other is the surviving fragment of Abelard's commentary on Boethius's De topicis differentiis, Glossae super De
topicis differentiis, which seems to belong with his other commentaries on the works of the logica vetus published as the Logica
"ingredientibus." The two expositions disagree on some crucial questions, but here I will restrict myself almost entirely to the discussion in the

2. The early years: Roscelin of Compiègne and William of Champeaux pp-21-42
"This chapter examines Abelard's intellectual debt to both the vocalist theories of Roscelin of Compiègne and William of Champeaux's teaching
about dialectic in shaping his philosophical nominalism. By looking at the earliest records of Abelard's teaching of dialectic and glosses on Aristotle,
Porphyry and Boethius, it observes how students identified him as an iconoclast teacher, who quickly provoked laughter by the examples that he chose. It traces
how Abelard's early conflict with his teachers laid the foundation for the subsequent difficulties he would experience in his career."
3. Challenging tje Tradition: the Dialectica pp. 43-57
"This chapter examines Abelard's Dialectica, his first major treatise on dialectic. The treatise is structured around an analysis both of the
major parts of speech, categories and of different kinds of argument, categorical and hypothetical. It argues that a driving theme is Abelard's desire to
counter the philosophically realist arguments presented by William of Champeaux."
5. Returning to Logica pp. 81-100
"This chapter examines the Logica 'Ingredientibus', a series of commentaries on Porphyry, Aristotle, and Boethius more profound than
any of his earlier glosses. I argue that in these commentaries Abelard adopts a much more profound theory of universals and of other parts of speech than in
the Dialectica. Rather than emphasizing differences of opinion with William of Champeaux, they demonstrate how far Abelard had come to distance himself from
the arguments of Boethius. Instead of speaking uniquely about dialectic, he is now interested in logica, the arts of language in general."

"Cette communication se borne a un bref examen de la signification de la phrase complète (propositio) dans la logique de Pierre
Il paraît utile de commencer par la définition du verbe signifier (significare) chez ce logicien.
'signifier' dit des mots (dictiones) c'est produire une intellection dans l'âme de l'auditeur (Logica

sens, le verbe est synonyme de appellare, nominare, demonstrare, designare.
'signifier' dit des phrases complètes (propositiones) c'est produire une intellection laquelle est formée par la liaison
des intellections de ses parties (dictiones)." p. 547
"On peut conclure que selon Abélard le dictum n'est pas un objet qui serait indépendent de la pensée, mais plutôt le contenu de la
pensée, c'est-à-dire une intellection objectivée, qui correspond soit à un état de choses réel, soit à un état de choses seulement possible (Dial.
II, 205, 28-30: id dicimus quod id quod dicit hec propositio 'Socrates est homo', est unum de his que natura patitur esse), soit un état de
choses tout à fait impossible (Dial. II, 158, 7-9: la proposition 'Socrates est lapis' ne reflète pas une inherentia de Socrate et
de pierre, ni 'Socrates non est lapis' leur rémotion).
Ainsi, l'existence qu'établit la proposition en parlant, n'est pas une existence réelle, mais, pourrait-on dire, une existence
parlée, ou plutôt, une existence pensée ou logique.
Employant la distinction bien connue du XIV siècles (presentée notamment par Jacques d'Ascoli, Thomas d'York, Pierre Thomae):
res: 1) extra animam (chose extérieure); 2) in anima: a) subiective ( = acte de l'intellection comme tel) b) obiective
(contenu de l'intellection).
on peut dire qu'Abélard a essayé, à sa façon, de montrer que le dictum, de la proposition, loin d'être une chose extérieure (res
extra animam) est une chose qui doit son existence à l'âme ou a l'intellection (res in anima), mais qu'il faut en même temps bien le distinguer
de l'acte de l'intellection pris comme tel (res in anima subiective), et reconnaître, sa propre identité dans le contenu objectif de
l'intellection. Par là, le dictum du grand logicien du XII siècle semble être d'une nature logique par excellence." pp. 554-555. (notes omitted)

"Mr. Tweedale's study is bound to give any of his readers the firm impression that, as logician, Peter Abailard has accomplished a tremendous
achievement. Unfortunately, however, Tweedale, (...) is on the wrong track in claiming-throughout his study that the modern interpreter has to 'ferret'
Abailard's answers out of 'rather obscure passages' (p. 7), and that he is inconsistent (p. X and passim). Tweedale has failed to appreciate
Abailard's lucidity and clear language. He has missed the point several times and more than once this is due to his defective knowledge of Latin. However, let
me not move too hurriedly to my conclusion.
In writing this book, the author had two main objectives in mind, as we learn from the Preface. First, 'to present in a form easily
accessible to professional philosophers, theologians and historians those scattered portions of Abailard's logical writings which seem to record a very
original scrutiny of the foundations of logic and in particular the problem of unversals'. Secondly, 'to interpret the texts in a way that would connect them
with the ancient tradition and also make them intelligible to contemporary philosophers.' So chapters I and II try to give an insight into the classical and
post-classical background. The core of the essay is to be found in Chapters III-V; Chapter VI contains a comparison between Abailard and Frege.
Without doubt, the author has succeeded in enlarging the modern scholar's acquaintance with, and admiration of, Abailard as a logician and
early Medieval philosopher and theologian. Even someone who has had only a glimpse of the contents of this rich essay, cannot help experiencing a kind of
thrill on realising that he is meeting in Peter Abailard a remarkable and original thinker.
However, to write a successful book something more is needed. To my mind the author was heavily hampered in realising the two objectives he
had set himself, as a result of his poor knowledge of (both classical and Medieval) Latin grammar and syntax. Sometimes his judgment of Abailard's achievements
is incorrect, for no other reason than his inability to correctly read Abailard's concise language." pp. 81-82

"The term syncategorema, translated by consignificantia, only exists in Greek in the Latin Institutiones of the
grammarian Priscien, and is introduced in the XIIth century in the grammatical commentaries, the couple of terms syncategorema / categorema emerging
even later, at the end of the XIIth century. Thus the discussions first focus on the terms connected to consignificare. The antique heritage is
multiple and diversified. Priscien uses, in a contradictory way, a functional criterium (a part which is not one of the main parts of speech is consignifying),
a semantic criterium (to be a part of speech is to indicate a concept of the mind), a criterium of autonomous meaning (something is said to consignify if it
does not signify by itself). Boethius uses the notion in five different ways, applying to various terms or morphemes: prepositions and conjunctions, parts of a
compound, tense, the verb to be, quantifiers. The Glosulae on Priscian, at the end of the XIth century, and especially in the later revision by
William of Champeaux, claim that the consignifying parts signify the thing signified by the word to which they are attached. Abelard, reading those gloses,
hesitates: the grammarian's solution is not satisfactory, but if, as Boethius wants it, the consignifying parts did not have any meaning, then it would not be
possible to explain the semantic role they have in the intellection of the whole proposition. He will thus devise a really innovative solution, which he
applies first to the copula and then extends to the other consignifying parts: they correspond to a mental act."

"Priscian's Institutiones Grammaticae, which rely on Stoic and Neoplatonic sources, constituted an important, although quite
neglected, link in the chain of transmission of ancient philosophy in the Middle Ages. There is, in particular, a passage where Priscian discusses the vexed
claim that common names can be proper names of the universal species and where he talks about the ideas existing in the divine mind. At the beginning of the
12th century, the anonymous Glosulae super Priscianum and the Notae Dunelmenses, which heavily quote William of Champeaux (as master G.),
interpret the passage in the context of a growing interest in the problem of universals, raising semantic as well as ontological questions, and introducing a
Platonic view on universals in the discussions on the signification of the noun. Moreover, this same passage will be used by Abelard to elaborate one of his
opinions about the signification of universal or common names-that they signify "mental conceptions".

Volume I of Language from Within.
Summary of the two volumes: "Volume I begins by setting up certain central principles of the natural ontology according to which humans
develop a theory of the actual world with the help of nonactual, thought-up 'worlds' or, better, situations. It then presents a view of how language expresses
thoughts developed in terms of this natural ontology, with an emphasis on the mechanism of reference not only to extensional, actually existing objects but
also to intensional, thought-up objects. An important aspect, elaborated in Chapter 4, is the fact that human communication does not, as is usually thought,
consist in the transfer of propositionally structured information, but, rather, in a socially binding form of position-taking with respect to such
We then go on to a discussion of the general semantic aspects of language in the context of the total ecological 'architecture' of language,
mind, and world.
This leads to a cursory tour of lexical meaning and of the ways lexical meanings are structured so as to make linguistic utterances fit into
given contexts or discourses.
Concentrating again on propositional content, basic principles of logic are introduced in Volume II, although not in the traditional fashion.
A new and unconventional view of logic is developed there, in which the logical constants are treated as lexical items, in fact as lexical predicates, with the
special property that their meanings allow for the computation of entailments. It is argued that this reduction of logic to lexical meaning shows better than
anything else the relevance of logic and logical analysis for the study of linguistic meaning. This point of view is reinforced in Chapter 10 of Volume II,
where it is shown that presuppositions are a general semantic property of lexical predicates and where it is argued that a proper theory of presuppositions
requires a trivalent presuppositional logic. We then concentrate, in Chapter 3 of Volume II, on a reconstruction of the natural logic which nature may be taken
to have instilled into human cognition.
This reconstructed logic is then placed in a historical perspective, which shows that basic natural predicate logic is, in fact, largely but
not entirely identical with the logic proposed and defended by the Edinburgh philosopherWilliam Hamilton in the nineteenth century. Aristotelian predicate
logic is dissected in Chapter 5 of Volume II and reconstructed on the basis of Aristotle's own texts, whereby it is found that Aristotle was not guilty of the
logical error of undue existential import but left his logic incomplete. It is also found that the twelfth-century French philosopher Abelard completed
Aristotelian predicate calculus in Aristotle's spirit, avoiding undue existential import in a way that leads to a logically sound system that is more powerful
than standard modern predicate logic. Chapter 4 of Volume II shows that traditional predicate logic, with its undue existential import, has maximal logical
power, in stark contrast to standard modern predicate logic, which has hardly any logical power left. It also shows that the logically sound Abelardian system
of predicate logic has much greater logical power than standard modern predicate calculus, while still staying within the bounds of a strictly extensional
ontology - a fact which raises questions regarding the status of standard modern predicate calculus in mathematics and mathematical logic.
In Chapter 6 of Volume II it is shown that traditional predicate logic is also much more functional from the point of view of transmitting
information than its standard modern counterpart. The fact that, as a matter of principle, linguistic utterances need anchoring in context before they can be
keyed to a given situation and the objects in it, is first discussed in Chapter 3, in the context of Aristotle's concept of proposition.
Chapters 7 to 9 of Volume II are devoted to a further theoretical elaboration of the context-sensitivity of natural-language sentences and
utterances. The notion of presupposition is central in this respect. Chapter 10 of Volume II is devoted to the logical aspects of the context-sensitivity of
language. A presuppositional logic is developed for both the propositional operators and the universal and existential quantifiers. In this logic, a
distinction is made between, on the one hand, a default, discourse-restricted area of metalogical relations, which is taken to have some degree of
psychological reality, and a purely theoretical area which has no psychological reality but is presented merely to show the character and properties of the
logic involved." (pp. 7-8).

"The main concern of the present paper is with some theories of significatio in the 12th century, and how intellectus and
imaginatio play a role in them, but not in others. In the present paper, I shall restrict my attention to Abelard and Ars meliduna, hoping to
ABELARD'S THEORY OF SIGNIFICATION
As for Abelard's theory, I will make some comments concerning the present subject, with a summary of the conclusions that I have described
elsewhere (1). In Glosse super Porphyrium ("Ingredientibus"), Abelard's theory of signification bound up with his explanation and revision of the
vocalist theory of a universal. He starts with the definition of the universal, which involves the idea of impositio and nominatio, and so
far the theory contains the name-things relationship only. Abelard, however, also shows its difficulties, by raising the two cardinal aspects of signification:
the first concerns nominatio, or significatio in the broader sense, while the second, the intellectus that a name produces in the
hearer, and this act of a name is significatio in the strict sense.
Then he tries to solve the difficulties and presents his revision of the theory regarding each of the two aspects (2)." (p. 927)
In sum, we can contrast Abelard and the Ars meliduna as for how intellectus are treated with reference to signification.
For both of them, a status is some thing or some fact in the world, independent of intellectus, though it might be an object of
but by no means a mental entity. This is the only point on which both will agree. To begin with, they oppose each other as for what is the
status. For Abelard, status is causa impositionis, while for the Ars meliduna, it is the object of signification. On the contrary,
intellectus is the object of signification for Abelard, while it is the causa impositionis for the Ars meliduna. Abelard thinks of
intellectus from the hearer's point of view basing himself on Aristotle's De interpretatione, so that he attends to the act of producing
intellectus in the hearer, while the Ars meliduna thinks of intellectus from the speaker's
point of view, basing itself on Priscian's grammar, so that it attends to the vocal words as revealing the speaker's intellectus.
Thus the Ars meliduna insists on the reverse of what Abelard insisted on." (p. 939).

Gasper, Giles E.M. and Helmut, Kohlenberger, 179-195. Toronto: Pontifical Institute of Mediaeval Studies.
"The medieval controversy about the nature of universals was about nothing other than the relationship between word and thing. In order to
understand the history and essence of the controversy, it is most important to examine the thoughts of the two key figures: Anselm and Abelard, respectively
the revered authority among the realists (reales), and the founder of the nominalists (nominales). Though there certainly lies a crucial
divergence in their views, nevertheless Abelard, as well as contemporary realists, owes many of his ideas, conceptions and terms to Anselm. Having examined
elsewhere their views on the relationship between word and concept, I would like to examine here those on the relationship between word and the world. Through
this examination I shall show how Anselm's metaphysical investigation about God's locution was transformed into Abelard's logical one about human words.
In the following, I shall first examine Anselm's theory of God's locution, showing how he explains it in terms of human language and in its
relationship with created things, by examining some passages from his Monologion and De grammatico.
Secondly, I shall focus my attention on Abelard's corresponding theories in his two commentaries on Porphyry, Glosse
'ingredientibus' and Glossule 'nostrorum petitioni sociorum'." p. 179
"Conclusion. The terms and concepts that Anselm proposed in his meditation on God's locution as the origin of created things constitute a
common vocabulary for the controversy about universals. Even Abelard, the founder of nominalism, when refuting the realists, uses these terms and concepts to
differentiate himself from them. Such terms, among others, are essentia, esse hominem, and status hominis, which is Abelard's substitute for
Anselm's esse hominis. Again, Anselm's idea of significatio as an act of producing understanding in the hearer becomes the main idea in
Abelard's semantics. We can, however, recognize elements of discrepancy between them as well as these examples of agreement. Abelard excludes essentia
from his theory of universals, separating it from esse hominem, and shifts the idea of esse hominis to the one of status hominis.
Again, Anselm's intellectus produced by a word is the understanding by which an essentia, or something's esse, is understood, and
the latter is based on the principalis essentia in God, while Abelard's is separated from essentia and even from the facts in reality
(status), in his later theory, though connected in his earlier one. It seems that Abelard cultivates a new realm of conceptions independent of things'
essentia; this realm is properly for human beings, not for God, the creator. In this sense, 'Deus homo' happened between Anselm and Abelard." p.

"The discussion of universals in Peter Abelard's Logica 'Ingredientibus' has been interpreted in many ways. Of particular controversy has
been the proper way to interpret his use of the term status. In this paper I offer an interpretation of status by comparing Abelard's account of knowledge of
universals to Edmund Husserl's presentations of categorial and eidetic intuition. I argue that status is meant to be understood as something like an ideal
object, in Husserl's sense of the term. First, I present Abelard's discussion of status and distinguish this term from universals, things, acts of
understanding, and forms. Next, I consider Husserl's account of categorial and eidetic intuition. Finally, I draw parallels between the two while showing how
an interpretation of status as ideal object overcomes the interpretive problems encountered by other commentators on Abelard."

"If Boethius's goal in his logical commentaries is to distinguish in order to unite, Abelard's goal seems simply to distinguish. Boethius's
construction of a narrative from Aristotle's cryptic remarks in the Peri hermeneias is one Abelard follows carefully and also criticizes, finding
Boethius's connections more a confusion than a synthesis of the elements in Aristotle's text. He argues that Boethius constructs a unity that is inauthentic,
which asserts a happy ending, a union between language, understanding, and the world that is not quite achievable. His own corpus of commentaries breaks down
this narrative to consider its parts much more carefully.
Abelard's perception of gaps in Boethius's narrative and his desire to take it apart is signaled in many ways. It comes across at a general
and formal level in his account of the relationship between the Categories and Peri hermeneias in his later glosses on Porphyry (known as the
Logica nostrorum petitioni sociorum). In these later glosses, he argues that Aristotle's two works are not two pieces of a single narrative, an
account of words leading to one of sentences, as Boethius claims (and as was a tradition Abelard himself Follows in his earlier glosses), but the separate
consideration of words insofar as they signify things (the Categories) and words insofar as they signify intellectus (the Peri
hermeneias) (LNPS 508. 32-37). Beginning with this division, then, I would like to consider Abelard's account of the distinction between words and things
in the earlier Glosses on Porphyry and the later gloss on Porphyry, and between words and understanding in the Commentary on the Peri
hermeneias. (10) I will attempt to examine the kind of a narrative Abelard constructs, insofar as he constructs any, of the processes of abstraction and
sentence construction." (pp. 66-67)

Porphyry and Commentary on the Peri hermeneias, both part of the Logica ingredientibus, are earlier (1118-20) than the later glosses on
Porphyry (here: LNPS) and De intellectibus (from the mid-1120s).

"I explain how Abailard thinks he can justify saying that certain items, particularly what is said by a sentence, are not things. His grounds
are that they are never referred to by any noun. He holds that nominalizations of sentences and of verbs, which appear to be nouns with such a reference, are
not logically speaking nouns, and sentences which have a nominalization for a grammatical subject do not have any logical subject."

"This work shows how Abailard elaborated and defended the view that universals are words, avoided the pitfalls of an image theory of
thinking, and propounded a theory of "status" and "dicta" as objects of thought without treating them as subjects of predication. His defense of these views is
shown to depend on certain fundamental departures from the Aristotelian term logic of his day, including a proposal for subjectless propositions, the treatment
of copula plus predicate noun as equivalent to a simple verb, and a transformation of the 'is' of existence into the 'is' of predication."

"Although both Ockham and Abailard admit that science is of necessary truths and is about what is common to many rather than concrete
particulars, Ockham claims knowledge has genuine objects, namely mental signs, while Abailard denies that knowledge has genuine objects. Ockham's position, it
turns out, cannot do justice to the objectivity of science and is in difficulties when it comes to explaining how we know these mental signs. Neither problem
afflicts Abailard's view."

contention that Abailard's doctrine on universals is not a form of conceptualism."

"Peter Abelard in his "Logica ingredientibus" proposed to solve the problems of genus and species which Porphyry had refused to answer in his
introduction to the "Categories" of Aristotle. The thesis of this paper is that Abelard, in spite of his diligent enquiry, could not explain genus and species
owing to his unanalyzed conception of an individual. Though Abelard failed in his inquiry, he did not fail philosophy, for he held firmly to the data: that
existents are individuals, that we have universal knowledge, and that universal knowledge is valid knowledge."

"The text in which Abelard attempts to reply, before 1120, to the questions left open by Porphyry on the statute of genera and species
furnished a reflection on the meaning of the universal term, understood since Aristotle as the possible predicate of a proposition true of several subjects
taken individually. Abelard refuses all the kinds of realism which he knows. The universal word ("vox, simplex sermo") has, however, more than the physical
aspect of an uttered sound; it has the three meanings of: the individual things to the extent that they resemble each other, the intellective activity of man
and the common conception with the aid of which it can function."

"Abelard maintains that individual words in a sentence represent distinct semantic units of its overall meaning. He employs two strategies to
defend this position in the face of troublesome counterexamples. One strategy-the earlier of the two-sacrifices normal intuitions about what a word is, often
labeling what seem to be words as non-signifying syllables. The later strategy invokes a rather fluid conception of what the signification of a word is,
allowing this signification considerable latitude to alter under the contextual influence of other words. This evolution of strategy is linked to a new
willingness on Abelard's part to adopt the principle of charity in interpreting sentences; this approach presumes the truth of the statement, and tries to find
an interpretation which bears that presumption out. This new willingness to adopt the principle is in turn linked to Abelard's developing vocation as an
interpreter of biblical texts."

"It is standard practice to develop an account of categorical logic which starts with a discussion of words, and moves through categorical
propositions to the categorical syllogisms themselves. Abelard consciously adopts a parallel course for the logic of hypotheticals by beginning with a
treatment of topics and hypothetical propositions. In general we can think of Abelard's development of material as falling along these two axes: discussion of
words and categorical propositions leading to categorical syllogisms; and then discussion of topics and hypothetical propositions leading to hypothetical
syllogisms. This way of organizing material is overtly embraced by Abelard in the Dialectica, in his attempt to depart from the commentary format. So
it can be taken as representing his most basic intuitions on how the subject matter of logic should be organized.
I will structure my discussion below accordingly. Part 1 deals with words, categorical propositions and categorical syllogisms. Part 2 deals
with topics, hypothetical propositions and hypothetical syllogisms. These two parts complete the treatment of Abelard, and Part 3 turns to his contemporaries
and their schools." (pp. 84-85).
