In a series of studies children show increasing mastery of irregular plural forms (such as mice) simply by producing erroneous over‐regularized versions of them (such as mouses). We explain this phenomenon in terms of successive approximation in imitation: Children over‐regularize early in acquisition because the representations of frequent, regular plural forms develop more quickly, such that at the earliest stages of production they interfere with children's attempts to imitatively reproduce irregular forms they have heard in the input. As the strength (...) of the representations that determine children's productions settle asymptotically, the early advantage for the frequent regular forms is negated, and children's attempts to imitate the irregular forms they have observed become more likely to succeed (a process that produces the classic U‐shape in children's acquisition of plural inflection). These data show that children can acquire correct linguistic behavior without feedback in a situation where, as a result of philosophical and linguistic analyses, it has often been argued that it is logically impossible for them to do so.

In appearance, Husserl’s writings seem not to have had any influence on linguistic research, nor does what the German philosopher wrote about language seem to be worth a place in the history of linguistics. The purpose of the paper is exactly to contrast this view, by reassessing both the position and the role of Husserl’s early masterpiece — the Logical Investigations — within the history of linguistics. To this end, I will focus mainly on the third (On the theory (...) of wholes and parts) and fourth (The distinction between independent and non-independent meanings) Investigations, paying special attention to Husserl’s mereology and to the idea of a general pure grammar. The paper tries to situate the third and fourth Logical Investigation within the general context of late nineteenth-century and early twentieth-century linguistics and furthermore attempts to show the historical and theoretical importance of the Logical Investigations for the birth and the development of one of the most important linguistic “schools” of the twentieth century, namely structural linguistics.

There is a great deal of research on the structure of narrative and its mode, and on the narrative positioning and counter positioning of the actor in legal and social contexts. In offender narratives, personal experiences are embedded for observation and analysis of particular realities that contextualize a disposition of the perpetrator being ‘an undergoer’ rather than an ‘effector’ of actions. This is evaluated in the shift from a narrated action to a speaker utterance in prospection and also in anticipation (...) of the criminal act. Using ‘grammatical logic’, it is also possible to demonstrate how the crucial event is not a cause, but an effect of a personal theme that encapsulates pattern of circumstances when the narrative outcome in criminal narrative becomes the product of its discursive practices. This is the ‘story of intentionality’ in crime narratives, characteristically embedded within the 1st the story of crime, the 2nd is the story of investigation [14, 20]. Using techniques from functional grammar and critical stylistics for discourse analysis, I intend to show an effective approach for the search of offender theme that underlies an act of crime. These disciplines provide the analyst with the linguistic material to analyse intersentential cohesion in a chain of semantically linked sentences that explore the ways in which things are ‘made to look’ in the structure and functions of the English language. As a case study, I am using an offender narrative from Tony Parker’s book Life After Life: Interviews with Twelve Murderers showing an effective approach for the search of personal themes underlying the act of crime. Offender theme analyses are also valuable for evaluating the changing nature or development of offender characteristics pre or post crime. (shrink)

What is the meaning of language expressions and how to compute or calculate it? In this paper, we give an answer to this question by analysing the meanings of aspects and tenses in natural languages inside the formal model of an grammar of applicative, cognitive and enunciative operations , using the applicative formalism, functional types of categorial grammars and combinatory logic . In the enunciative theory and following , an utterance can be decomposed into two components: a modus and (...) a dictum . In GRACE, the modus is a complex operator applied to a proposition and is generated from more elementary operators of the categories of tense, aspect, and modality. The dictum is a proposition generated by a predicative relation. In this way, we can attribute a semantic meaning to different grammatical aspecto-temporal operators. The applicative expressions of CL can be easily translated into a functional programming language such as HASKELL or CAML. (shrink)

Multiple generality has long been known to cause confusion. For example, “Everyone has a donkey that is running” has two readings: either (i) there is a donkey, owned by everyone, and it is running; or (ii) everyone owns some donkey or other, and all such donkeys run. Medieval logicians were acutely aware of such ambiguities, and the logical problems they pose, and sought to sort them out. One of the most ambitious undertakings in this regard is a pair of massive (...) diagrams (magnae figurae) which map out the logical interrelations of two sets of doubly-general forms. These appear in a fourteenth-century MS of John Buridan’s Summulae de Propositionibus. In this paper, I present these diagrams, and determine the truth conditions of their different forms. To that end, I have developed a bespoke system of diagrams to display their truth conditions. As we will see, such forms present significant difficulties for an all-encompassing account of the role form plays in logic. Accordingly, they can tell us important things about the role logical form plays in Buridan’s account of logical foundations. (shrink)

In a classical paper [15] V. Glivenko showed that a proposition is classically demonstrable if and only if its double negation is intuitionistically demonstrable. This result has an algebraic formulation: the double negation is a homomorphism from each Heyting algebra onto the Boolean algebra of its regular elements. Versions of both the logical and algebraic formulations of Glivenko’s theorem, adapted to other systems of logics and to algebras not necessarily related to logic can be found in the literature (see (...) [2, 9, 8, 14] and [13, 7, 14]). The aim of this paper is to offer a general frame for studying both logical and algebraic generalizations of Glivenko’s theorem. We give abstract formulations for quasivarieties of algebras and for equivalential and algebraizable deductive systems and both formulations are compared when the quasivariety and the deductive system are related. We also analyse Glivenko’s theorem for compatible expansions of both cases. (shrink)

Cognitive, or knowledge, agents, who are in some way aware of describing their own view of the world (based on their mental concepts), need to become concerned with the expressions of their own conceptions. My main supposition is that agents’ conceptions are mainly expressed in the form of linguistic expressions that are spoken, written, and represented based on e.g. letters, numbers, or symbols. This research especially focuses on symbolic conceptions (that are agents’ conceptions that are manifested in the form (...) of their symbols). I attempt to logically (and using ????LSYM) analyse symbolic conceptions in terminological systems. ????LSYM is an assertional fragment of my developed Conception Language (????L), which is utilised as a formal-logical system for representing and explicating agents’ conceptions of the world. Keywords: assertional logic; cognitive agent; knowledge agent; conception language; conception; symbol; symbolic conception. (shrink)

The present study focuses on a grammatical category called evidentiality. The primary meaning of evidentiality is concerned with information source. That is, it expresses whether something has been seen, heard or inferred. The aim here is to conduct a conceptual study of evidentiality in which use is made of formal tools. The fundamental intuition is that the distinction between ‘evidence’as ‘proof’and ‘evidentiality’as ‘to do with proof’is a crucial one. Evidentiality is a dynamic notion to be analysed through the use of (...) knowledge by the agents, a knowledge in action, which involves an in-coming state and an out-coming state that is typical of the transmission of information. We propose our own approach in which the dynamics of knowledge in action is grasped in the context of a dynamic epistemic logic. (shrink)

There is a well-documented paradigm-shift in eighteenth century Jesuit philosophy and science, at the very least in Central Europe: traditional scholastic version(s) of Aristotelianism were replaced by early modern rationalism (Wolff's systematisation of Leibnizian philosophy) and early modern science and mathematics. In the field of probability, this meant that the traditional Jesuit engagement with probability, uncertainty, and truthlikeness (in particular, as applied to moral theology) could translate into mathematical language, and can be analysed against the background of the accounts (...) of probability, pre-mathematical Jesuit logic, Wolff's conceptual analysis, and Bernoullian mathematisation. The works of two Jesuit philosophers, Berthold Hauser and Sigismund Storchenau, can be related to this context. The core of their logic of (epistemic) probability is the account of negation (or ‘contradiction’) and implication (or ‘argument’), in particular, the algorithms for computing the reliability of one piece of evidence when compared to the respective counter-evidence and for computing the probability of a conclusion given the probability of its premises.

In the past 20 years, the concept of instinct has been discussed in respect to various disciplines such as evolutionary biology, evolutionary psychology, linguistics, ethics, aesthetics, and phenomenology, etc. However, the meaning of instinct still remains unclarified in many respects. In order to overcome this situation, it is necessary to elucidate the genuine meaning of instinct so that the discussion of instinct in these disciplines can be carried out systematically. The objective of this paper is to establish the genuine concept (...) of instinct on the basis of a phenomenological criticism of A. Gehlen’s theory of instinct-reduction. Moreover, it seeks to show that this concept is the genetic origin of the embodied consciousness. According to Gehlen, instinct is defined as Instinkthandlung. However, this definition of instinct is problematic in the formal logical sense, since the definiendum is already included in the definiens. Moreover, it faces different kinds of serious material problems. Criticizing Gehlen’s theory of instinct systematically, I will show that instinct should be redefined as “the innate living force that urges a species of living being to pursue a certain kind of object,” and I will attempt to clarify this definition of instinct in a more detailed manner by offering 11 points. Thereafter, I will argue that Gehlen’s theory of instinct-reduction has to be replaced by the theory of instinct-enlargement in human beings. Finally, I will point out that the genuine concept of instinct is nothing other than the genetic origin of the embodied consciousness. (shrink)

The aim of the article is to present the results of research conducted as part of the project Polonica Philosophica Orientalia: namely, to give an overview of the most important logical and metaphysical treatises written in Vilnius between the sixteenth and eighteenth centuries that are currently accessible in some of the Vilnius libraries. Although the research focused primarily on the Vilnius University Library and its resources, some interesting results were also obtained while researching the Wróblewski Library of the Lithuanian Academy (...) of Sciences. Most sources containing information about the state and the nature of metaphysical and logical investigations conducted in Vilnius during the period discussed are the manuscripts of lecture courses delivered for the students of Vilnius University and other schools. The analysis of those manuscripts has revealed a strong and long-lasting influence of scholastic Aristotelianism in both logic and metaphysics. Namely, up to the mid-eighteenth century, the main questions discussed in logic were Aristotelian syllogism, the square of opposition and the medieval topics of semantical antinomies, modalities and supposition theory, while investigations into metaphysical issues were limited to commentaries on Aristotle’s theoretical treatises without seriously questioning their main theses. In the second part of the eighteenth century, a moderate shift towards subjectivism and psychologism was observed in both of these disciplines. This was influenced by modern epistemologists. Logicians and metaphysicians of Vilnius University developed an interest in the topics of human understanding and cognition. However, this shift did not take a radical form – while the majority of eighteenth-century authors sought a combination of scholastic and modern ideas, a critical and even hostile stance towards modern philosophy and science is still noticeable in many of the analysed sources. An overview of the research supported by statistical data is followed by some preliminary remarks on how and where investigation of this topic might be continued in the future. (shrink)

This paper defends 'plural reference', the view that definite plurals refer to several individuals at once, and it explores how the view can account for a range of phenomena that have been discussed in the linguistic literature.

This paper presents a novel semantic analysis of unit names (like pound and meter) and gradable adjectives (like tall, short and happy), inspired by measurement theory (Krantz et al. In Foundations of measurement: Additive and Polynomial Representations, 1971). Based on measurement theory’s four-way typology of measures, I claim that different adjectives are associated with different types of measures whose special characteristics, together with features of the relations denoted by unit names, explain the puzzling limited distribution of measure phrases, as well (...) as unit-based comparisons between predicates (as in the table is longer than it is wide). All considered, my analyses support the view that the grammar of natural languages is sensitive to features of measurement theory. (shrink)

Whether truth is absolute or relative has been a widely discussed topic for over two thousand years in epistemology and the philosophy of science. However, this issue has not yet been discussed systematically with respect to linguistics. The present paper attempts to make the first step toward filling this gap. It raises the following question in Sect. 1: What kind of relationship is there between the pluralism of inquiry, the relativistic and the absolutistic approach to truth, and the tolerance of (...) views differing from one’s own in the practice of linguistic research? After Sect. 2 has clarified what is meant by ‘relativism’, ‘absolutism’, ‘pluralism’ and ‘tolerance’, Sects. 3–5 describe, analyse, and systematize the ways in which relativistic and absolutistic views are manifested in linguistic theorizing. Finally, Sect. 6 summarizes the findings and gives a sophisticated answer to the main question of the paper. (shrink)

The rosy dawn of my title refers to that optimistic time when the logical concept of a natural kind originated in Victorian England. The scholastic twilight refers to the present state of affairs. I devote more space to dawn than twilight, because one basic problem was there from the start, and by now those origins have been forgotten. Philosophers have learned many things about classification from the tradition of natural kinds. But now it is in disarray and is unlikely (...) to be put back together again. My argument is less founded on objections to the numerous theories now in circulation, than on the sheer proliferation of incompatible views. There no longer exists what Bertrand Russell called ‘the doctrine of natural kinds’—one doctrine. Instead we have a slew of distinct analyses directed at unrelated projects. (shrink)

This collection of articles and review essays, including many hard to find pieces, comprises the most important and fundamental studies of Indian logic and linguistics ever undertaken. Frits Staal is concerned with four basic questions: Are there universals of logic that transcend culture and time? Are there universals of language and linguistics? What is the nature of Indian logic? And what is the nature of Indian linguistics? By addressing these questions, Staal demonstrates that, contrary to the general (...) assumption among Western philosophers, the classical philosophers of India were rationalists, attentive to arguments. They were in this respect unlike contemporary Western thinkers inspired by existentialism or hermeneutics, and like the ancient Chinese, Greeks, and many medieval European schoolmen, only--as Staal says--more so. Universals establishes that Asia's contributions are not only compatible with what has been produced in the West, but a necessary ingredient and an essential component of any future human science.

Description Logics (DLs) are a family of well-known terminological knowledge representation formalisms in modern semantics-based systems. This research focuses on analysing how our developed Occurrence Logic (OccL) can conceptually and logically support the development of a description logic. OccL is integrated into the alternative theory of natural language syntax in `Deviational Syntactic Structures' under the label `EFA(X)3' (or the third version of Epi-Formal Analysis in Syntax, EFA(X), which is a radical linguistic theory). From the logical point of (...) view, OccL is a formal logic that mainly deals with the occurrences of symbols as well as with their priorities within linguistic descriptions, i.e. natural language syntax, semantics and phonology. In this article---based on our OccL-based definitions of the concepts of `strong implication' and `occurrence value' as well as of the logical concept `identical occurrence constructor (IDOC)' that is the most fundamental logical concept in our formalism---we will model Occurrence Description Logic ($\mathcal{ODL}$). Accordingly, we will formally-logically analyse `occurrence(s) of symbol(s)' within descriptions of the world in $\mathcal{ODL}$. In addition, we will analyse and assess the logical concepts of `occurrence' and `occurrence priority' in $\mathcal{ODL}$. This research can make a strong logical background for our future research in the development of a Modal Occurrence Description Logic. (shrink)

In the view of my philosophical position “nominal conceptualism”, cognitive/knowledge agents, who are in some way aware of expressing the world based on their mental concepts, deal with their linguistic and/or symbolic expressions. In this paper I rely on nominal conceptualism to logically characterise agents’ concept-based descriptions of the world and analyse a fundamental logical system for conception representation.

Teaching the art of profession-related communication to students of non-linguistic study fields allows instructors to explain their students how to keep up the conversation using facts, data, concepts etc. specific to the area of their future profession. It activates the acquisition processes as well as increases students' motivation to study. The formation of oral monologue speaking skills in students of non-linguistic study fields is one of the tasks within the course of Foreign ( English) Language for Specific Purposes.This (...) process is associated with certain difficulties, which can inhibit learning and demotivated students to study. Among strategies and techniques aiding learning that can be used to improve performance and study outcomes during the course and can be implemented for the enhancement of speaking on occupation-related topics, the mind mapping technique is of specific relevance. It can serve as an interesting and useful tool serving to enhance quality of oral speaking skills in students majoring in Psychology as the representatives of non-linguistic study fields. The article analyses the carried out research concerning the facilitating impact of mind mapping on the oral speech performance of Psychology students. The study hypothesis implies that the use of the mind-mapping technique in the process of preparing for and presenting the talk in the study sessions enhances students' oral monologue speech performance. In order to check the hypothesis, we have conducted the experiment in Bohdan Khmelnytsky National University of Cherkasy at the Department of Psychology. The study involved 46 first-year students, including 34 female and 12 male participants. The respondents were randomly assigned to the experimental mind-mapping group of 23 students ( including 6 males) and the control group of 23 students ( including 6 males as well). The students in the experimental group were involved into the experiment using the mind-mapping technique during their study, and the students in the control group continued their study in the usual way. The hypothesis was confirmed. The mind map use stimulates activity of both brain hemispheres, thus making it easier for students to memorize thematic vocabulary, follow the logical sequence of the talk when speaking. The research findings have shown the effectiveness of implementing the mind-mapping technique into the university course teaching English for Specific Purposes to develop, advance and master students' professional communicative competence. Consistent use of mind maps will also promote the educational process efficiency and have positive effects on the general formation of competitive skilled specialists. (shrink)

L’addition, dans la cinquième édition en 1683 de La Logique ou L’Art de penser, d’un chapitre consacré à la définition générale du signe et de plusieurs chapitres relevant spécifiquement d’une analyse des signes linguistiques, a été parfois interprétée comme une apparition tardive du “problème du langage” dans le traité d’Arnauld et Nicole. Parce que la plupart de ces chapitres supplémentaires sont la transposition de passages auparavant destinés dans la Perpétuité de la foi (1669-1674) à réfuter le sens calviniste de Ceci (...) est mon corps, on a été enclin à attribuer l’importance de la question du signe et du “problème du langage” dans l’édition de 1683 à une origine théologique. J’essaie au contraire de montrer que, dès la première édition de L’Art de penser en 1662, la problématisation des écarts des expressions linguistiques avec une correspondance terme à terme entre les mots et les idées a été indissociable pour Port-Royal de l’analyse des opérations de l’esprit. Selon moi, dans la Perpétuité de la foi, la critique du sens calviniste de la formule eucharistique constitue elle-même une application de cette analyse logique du langage : les passages incorporés ensuite dans L’Art de penser sont dans le prolongement des réflexions de 1662 sur les difficultés d’adéquation entre le dire et le vouloir-dire. Je montre pour finir que la définition générale du signe à Port-Royal suppose une restructuration de la définition augustinienne du De doctrina christiana, et fonde en 1683 une identification de la relation de signification linguistique à un rapport de représentation des mots aux idées, qui vient redoubler le rapport de représentation des idées aux choses établi en 1662.

Among the important conceptual innovations introduced in the second scholasticism era and motivated by theological debates following the Council of Trent were the theories of moral necessity and moral implication. As they were centred upon a view of moral necessity as a form of necessity weaker than physical necessity, and moral implication as weaker than physical implication, some interpretations of moral necessity encouraged the logic of statistical hypotheses and probability. Three branches of this debate are studied in this paper: (...) the explanation of moral necessity in terms of suppositio, the confrontation over the interpretation of moral necessity, and the theory of statistical quantification.

Combining logics has become a rapidly expanding enterprise that is inspired mainly by concerns about modularity and the wish to join together tailor made logical tools into more powerful but still manageable ones. A natural question is whether it offers anything new over and above existing standard languages. By analysing a number of applications where combined logics arise, we argue that combined logics are a potentially valuable tool in applied logic, and that endorsements of standard languages often miss the (...) point. Using the history of quantified modal logic as our main example, we also show that the use of combined structures and logics is a recurring theme in the analysis of existing logical systems.

Linguistic Issues in Language Technology (LiLT) is an open-access journal that focuses on the relationships between linguistic insights and language technology. In conjunction with machine learning and statistical techniques, deeper and more sophisticated models of language and speech are needed to make significant progress in both existing and newly emerging areas of computational language analysis. The vast quantity of electronically accessible natural language data (text and speech, annotated and unannotated, formal and informal) provides unprecedented opportunities for data-intensive analysis (...) of linguistic phenomena, which can in turn enrich computational methods. Taking an eclectic view on methodology, LiLT provides a forum for this work. In this volume, contributors offer new perspectives on semantic representations for textual inference. (shrink)

This volume provides analyses of the logic-reality relationship from different approaches and perspectives.

Theories of adverbial modification can be roughly distinguished into two sorts. One kind of theory takes logical form to follow surface grammatical form. Adverbs are treated as unanalyzable logical operators that turn a predicate or sentence into a different predicate or sentence respectively. And new rules of logic are stated for these operators. -/- A different kind of theory does not suppose that logical form must parallel surface grammatical form. It allows that logical form may have more to do (...) with deeper structures that might be studied in transformational grammar. Adverbs are treated as surface forms of the underlying predicates represented by corresponding adjectives and verbs. 'Slowly' is derived from 'slow'; 'intentionally' from 'intentional' or 'intend'; etc. And new rules of logic are avoided where they can be. -/- In this paper I attempt to state some of the advantages of the second sort of theory. My procedure will be this. First, I will try to say in outline what theories of logical form are. Then I will state five principles for evaluating such theories. Next, I will sketch the sorts of analyses acceptance of principles (1)-(5) leads to. In particular I will talk about adverbial phrases (e.g. locatives) that are best analyzed in terms of implicit references to events, relative modifiers (like 'large') which relate something to a comparison class, and 'that' clauses taken as names of propositions. By appealing to principles (1)-(5) I will defend these analyses against certain others, one that appeals to many logical operators, a second that treats all sentences as names of propositions, and a third that sees implicit reference to possible worlds in the language being analyzed. Finally, I will offer a pragmatic defense of my approach in terms of principles (1)-(5) as against a different approach that appeals to possible world semantics. (shrink)

Logical analysis of the applicability of nominals (which are introduced by hybrid logic) in the formal descriptions of the world (within modern knowledge representation and semantics-based systems) is very important because nominals, as second sorts of propositional symbols, can support logical identification of the described world at specific [temporal and/or spacial] states. This paper will focus on answering the philosophical-logical question of ‘how a fundamental world description in description logic (DL) and a nominal can be related to each (...) other?’. Based on my assumption that nominals can support more adequate identification of the world in DL, this paper will deal with the concept of ‘world identification’. Accordingly, based on a logical-terminological analysis of nominals, the paper will analyse hybridised fundamental world descriptions. The research will finally reach the idea that we can have a hybrid description logic based on the analysed concepts. (shrink)

In a seminal modern work of uṣūl al-fiqh, al-Ākhund al-Khurāsānī argues that the two terms ṭalab and irāda are coined to refer to a single concept. Within the argument he implies that the Ashʿarīs, and some modern Twelver Shīʿa who lean towards their position, fall foul of a linguistic fallacy when they assert that ṭalab and irāda are distinct. For al-Khurāsānī, both ṭalab and irāda may be used in two distinct modes, a real mode or an initiating mode. The (...) former denotes a real seeking or willing within the essence of an actor, whereas the latter simply seeks to initiate the meaning of seeking or willing. Accordingly, an initiating ṭalab may be distinct from a real irāda, and a real ṭalab may be distinct from an initiating irāda, without undermining the position that ṭalab and irāda are conceptually identical. Analysis of al-Khurāsānī’s arguments, and some criticisms of it by later modern and contemporary scholars of uṣūl al-fiqh, will aim to broaden our understanding of the category of inshāʾ in Arabic, hitherto analysed through the lens of J. L. Austin’s notion of performatives. More generally, the paper takes the treatment of this linguistic issue as an example affirming the continued importance of modern and contemporary uṣūl al-fiqh for engaging with Arabic philosophy of language and argument.

In a multiagent and multi-cultural world, the fine-grained analysis of agents’ dynamic behaviour, i.e. of their activities, is essential. Dynamic activities are actions that are characterized by an agent who executes the action and by other participants of the action. Wh-questions on the participants of the actions pose a difficult particular challenge because the variability of the types of possible answers to such questions is huge. To deal with the problem, we propose the analysis and classification of Wh-questions apt for (...) agents’ communication in a multiagent system (MAS). Our proposal of such a system consists of agents who communicate with their fellow agents by messaging so that each autonomous agent, though resource-bounded, can make less or more rational decisions to meet its own and collective goals. In addition, by communicating with other fellow agents and their environment, agents can learn new concepts and enrich their ontology so that their behaviour is dynamic. We aim to make a general proposal of the system so that the ‘envelope’ of agents’ messages can be formalized in any MAS standard, be it The Foundation for Intelligent Physical Agents - Agent Communication Language (FIPA-ACL) or Knowledge Query and Manipulation Language (KQML). Yet, the content of messages is encoded in a formalized natural language. To this end, we apply Transparent Intensional Logic (TIL) with its procedural semantics which is particularly apt for a fine-grained analysis in which all the semantically salient features of natural language can be plausibly formalized. In this paper, we concentrate on analysing the content of query messages, particularly the content of those that encode Wh-questions and the answers to them. We also summarize TIL deduction system that makes it possible to answer such questions in an intelligent way. Linguists distinguish several subtypes of Wh-questions. Though the linguistic classification is helpful, it is not always suitable for agents’ communication and reasoning. We need the classification based on a logical analysis of Wh-questions so that the agents can infer possible answers to such questions rather than only looking for them by keywords. This paper aims to apply an appropriate classification of the logical types of Wh-questions and the analysis of such questions; we concentrate in particular on questions concerning the participants of activities. The application of these results to the analysis of processes and events based on verb valency frames is another novelty of the paper. (shrink)

B a c k g r o u n d. The article is devoted to the analysis of the key directions of the study of the possible influence of the specifics of Chinese language culture on the content and nature of intellectual discourse, which is recognized as philosophical. Logic and ontology are the key areas of analysis of the possible influence of linguistic determinants on the intellectual discourse of China. Three main topics that attract the attention of researchers (...) are the structure of judgment, the semantics of lexical units, and the specificity of the pragmatics of the Chinese language. M e t h o d s. The author applied general scientific methods of analysis, synthesis, comparison and description of the works of researchers of Chinese philosophy, which justify and argue the fruitfulness of studying the peculiarities of Chinese language to explain the reasons of the fundamental difference between the problems actualized in the history of Chinese philosophy and those that formed the basis of the development of the history of philosophy in the Western world. R e s u l t s. It is generally accepted that for the worldview of representatives of Chinese culture, the world is a structural whole, consisting of elements that continuously interact in the dynamics of changes and transformations, we find a reflection of this feature in the semantics of the corresponding symbolic system. Polysemy in the Chinese language mostly reveals a complex and multi-layered "web" of associative and correlative connections between meanings, which in fact cannot be argued outside the context of the relevant cultural tradition indicating common features or similarities of the signified. The doubt about the typicality of understanding the denotations as fixed and atomized for the Chinese language culture is reasonable, even in those cases when it comes to the designation of empirically accessible objectivity. The main specific features of polysemy in the Chinese language are the complete heterogeneity of what is signified, and the lack of transparent grounds for identifying the genus-species subordination of the scope of general concepts. This can also serve as an explanation for the fact that we do not find a completely obvious and nondisputable analogue of the problem of universals of the Western model in the history of Chinese philosophy. C o n c l u s i o n s. Based on the peculiarities of the Chinese language culture, we can recognize as a reasonable a statement that the seemingly natural understanding of the essence – the subject, as something that remains the same (at least for a certain time), but it undergoes some changes through its manifestations – a predicate (properties and actions). It is not as necessary and axiomatic for Chinese thinkers as, for example, for ancient Greek philosophers. In addition, we can recognize the fact that the verb "to exist" does not fulfill the role of a necessary copula in judgments in the Chinese language, as a probable reason for the lack of fundamental problematization of the concept of "being" in the Chinese history of philosophy. In general, the context of the use of a certain word-sign in the Chinese language plays a determining role. The actualization of one or another meaning in an expression is formed not only by its integration into a certain text, but also by its purpose in accordance with the specific practice of application. Therefore, this can serve as an explanation for the absence of an original and axiomatic interpretation of truth as absolute, that is, unchanging and non-relative in the history of Chinese philosophy.

The book contains a systematical and very accurate introduction into the scholastic philosophy. It begins with part one containing logic and dialectic. Part two deals with metaphysics and ontology. Part three examines cosmology, followed by the fourth part which embraces rational psychology. Part five deals with natural theology. In spite of its systematic architecture the book exemplifies the skill of the author to write a very comprehendible text that can be read with profit by undergraduates.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 127 from Adam, and inheriting "real sins" with real "guilt." From his De libero arbitrio onward, Augustine sees that if Adam's is the sin of someone "other" than ourselves, then it is alienum to us, is simply not "our" sin, and we cannot be held "guilty" of it. On the other hand, he is willing to accept that God might fittingly decree that Adam's descendants "inherit" the (...) debt, obligation, weakness, sickness, or mortality (choose the Augustinian metaphor you prefer) that is appropriate punishment for the sin which Adam (personally) committed. But, at bottom, Rigby and Sage have the same difficulty: both assume that Augustine was a "creationist," when he was not. For he saw that creationism must necessarily view our individual souls as metaphysically "other" than Adam's, so that God could never judge us guilty of that "other's" sin. Rigby would have been wiser to combine and extend the insights he himself quotes from Huftier (59 n. 14), Bonner (78-79: omnes fuimus ille unus), TeSelle (86), Confessions 4.31 ("by our own act": nos inde ruimus), and Rondet (121 n. 6). Augustine thought that we sinned the original sin (nos inde ruimus) precisely because we were metaphysically identical with our father Adam: fuimus iUe unus. I submit that the very same theory, making our souls identical with Adam's, subtends both the Confessions and Augustine's anti-Pelagian writings. ROBERT J. O'CONNELL Fordham University Mark D. Johnston. The Spiritual Logic of Ramon LluU. New York: Oxford University Press, 1987. Pp. x + 336. $65.oo. In the last twenty-five years a considerable number of scholars have turned their attention to the sort of formal logic found in the writings of the Catalan polymath, Ramon Lull (d. x316). This attention has run parallel to the current interest in medieval logic and linguistic theory, although Lull was less concerned with the theory of the properties of terms than with formulating a realistic theory of the predicables and categories and a new theory of demonstration. In the work under review Mark Johnston provides us with a study of Lulrs logic which is systematic in character. His work represents a first attempt to go beyond the studies of individual points of doctrine and to situate the development of Lulrs logic within the context of the evolution of the Ars lulliana. The work is divided into two parts. The first part analyzes the early writings to the year 13o3, the second the later ones composed between 13o3 and 1316. Johnston takes the very early Compendium logicae Algazelis as his point of departure for the first part and the Logica nova of 13o3 as that for the second part. He describes Lull's thought following the sequence of the different tracts of the Aristotelian logic and relates its development to the biography of the Majorcan philosopher. Throughout his study Johnston emphasizes three special characteristics in Lull's approach: its popular nature, its extreme realism, and its moralizing intention. Lull's works were composed both in Latin and in Catalan and aimed at an audience quite different than that of the clerical universities of the Middle Ages. His approach as- 128 JOURNAL OF THE HISTORY OF PHILOSOPHY 28"1 JANUARY 199o sumed a natural ontology, realist and "essentialist," which was of Avicennian derivation. His argumentation presupposed the idea that individual beings are concrete realizations of abstract essences situated in a scala creaturarum which leads in degrees to the divinity. The idea of basing philosophical discourse on the hierarchical structure of creation appealed to Lull because in it he found something common to the Christian, Jewish, and Islamic traditions. This fact made his logic necessarily an extremely realist one, consciously opposed to the logic of the Scholastics. From the extreme realism of Lulrs logic to his moralizing intent, it is but a step. To explain the status of things as real, Lull formulated a tropological exegesis of creation by way of the scala creaturamtm. Johnston accordingly directs our attention to the importance of analogy in Lull's logic. The analogical character of Lulrs logic had indeed been emphasized by the brothers Carreras y Artau in their history of Spanish philosophy... (shrink)

This Handbook documents the main trends in current research between logic and language, including its broader influence in computer science, linguistic theory and cognitive science. The history of the combined study of Logic and Linguistics goes back a long way, at least to the work of the scholastic philosophers in the Middle Ages. At the beginning of this century, the subject was revitalized through the pioneering efforts of Gottlob Frege, Bertrand Russell, and Polish philosophical logicians such (...) as Kazimierz Ajdukiewicz. Around 1970, the landmark achievements of Richard Montague established a junction between state-of-the-art mathematical logic and generative linguistic theory. Over the subsequent decades, this enterprise of Montague Grammar has flourished and diversified into a number of research programs with empirical and theoretical substance. This appears to be the first Handbook to bring logic-language interface to the fore. Both aspects of the interaction between logic and language are demonstrated in the book i.e. firstly, how logical systems are designed and modified in response to linguistic needs and secondly, how mathematical theory arises in this process and how it affects subsequent linguistic theory. The Handbook presents concise, impartial accounts of the topics covered. Where possible, an author and a commentator have cooperated to ensure the proper breadth and technical content of the papers. The Handbook is self-contained, and individual articles are of the highest quality. (shrink)

In the paper we analyse the problem of axiomatizing the minimal variant of discussive logic denoted as $$ {\textsf {D}}_{\textsf {0}}$$ D 0. Our aim is to give its axiomatization that would correspond to a known axiomatization of the original discussive logic $$ {\textsf {D}}_{\textsf {2}}$$ D 2. The considered system is minimal in a class of discussive logics. It is defined similarly, as Jaśkowski’s logic $$ {\textsf {D}}_{\textsf {2}}$$ D 2 but with the help of the (...) deontic normal logic $$\textbf{D}$$ D. Although we focus on the smallest discussive logic and its correspondence to $$ {\textsf {D}}_{\textsf {2}}$$ D 2, we analyse to some extent also its formal aspects, in particular its behaviour with respect to rules that hold for classical logic. In the paper we propose a deductive system for the above recalled discussive logic. While formulating this system, we apply a method of Newton da Costa and Lech Dubikajtis—a modified version of Jerzy Kotas’s method used to axiomatize $$ {\textsf {D}}_{\textsf {2}}$$ D 2. Basically the difference manifests in the result—in the case of da Costa and Dubikajtis, the resulting axiomatization is pure modus ponens-style. In the case of $$ {\textsf {D}}_{\textsf {0}}$$ D 0, we have to use some rules, but they are mostly needed to express some aspects of positive logic. $$ {\textsf {D}}_{\textsf {0}}$$ D 0 understood as a set of theses is contained in $$ {\textsf {D}}_{\textsf {2}}$$ D 2. Additionally, any non-trivial discussive logic expressed by means of Jaśkowski’s model of discussion, applied to any regular modal logic of discussion, contains $$ {\textsf {D}}_{\textsf {0}}$$ D 0.

We discuss in this paper the question of the scope of the principle of tolerance about languages promoted in Carnap's The Logical Syntax of Language and the nature of the analogy between it and the rudimentary conventionalism purportedly exhibited in the work of Poincaré and Hilbert. We take it more or less for granted that Poincaré and Hilbert do argue for conventionalism. We begin by sketching Coffa's historical account, which suggests that tolerance be interpreted as a conventionalism that allows us (...) complete freedom to select whatever language we wish—an interpretation that generalizes the conventionalism promoted by Poincaré and Hilbert which allows us complete freedom to select whatever axiom system we wish for geometry. We argue that such an interpretation saddles Carnap with a theory of meaning that has unhappy consequences, a theory we believe he did not hold. We suggest that the principle of linguistic tolerance in fact has a more limited scope; but within that scope the analogy between tolerance and geometric conventionalism is quite tight. (shrink)

One of the fields of protecting human rights within the framework of standards of the Council of Europe is the protection of national minorities – with the special issue of their linguistic rights. An intensification of actions aimed at adopting legal measures in this field happened in the 1960s. The concern for a proper range and level of regulation was expressed at the level of the Parliamentary Assembly and the Committee of Ministers. National experts formulated detailed resolutions to include (...) the goals of international organizations such as CSCE and the United Nations concerning this matter. The fact that the framework convention was chosen as the means bears witness to a significant provision that the guarantee of rights were realized in the most flexible manner, including the designations and capacities of State parties. This article includes an analysis of three stages of work connected with ensuring linguistic rights for national minorities, with a special emphasis on the linguistic rights in the education system. On the one hand, actions which resulted in the acceptance of the Framework Convention for the Protection of National Minorities are shown. On the other hand, the goals and details of this Convention are described. The third section concerns the analysis of mechanisms for monitoring the realization of the rights included in the Convention. Due to limitations in the terms of reference for this work, the analysis of the convention guarantees, and their realization, was limited to linguistic rights in the education system. The practice of these actions was shown through examples in Poland and Lithuania. The right to education for national minorities including knowledge about their culture, traditions, and their input into the development of the society of a given country is one of the rights clearly stated in the Framework Convention. By the same token are linguistic rights in an education system – the right to teach the language of a national minority or to teach in the language of a minority. As practice in Poland and Lithuania shows, the situation of education of national minorities is different, although some of the problems are common: an example for that would be access to proper coursebooks in the languages of national minorities, or properly trained teachers.
