RésuméĽauteur propose ?illustrer et ?expliquer le concept de comprehension en reprenant le probleme de I'asymetrie des sujets et des predicats tel que P. F. Strawson ľa posé et partiellement résolu. II s'agit de comprendre, en un sens fort, le phénomene de ľasymétrie. Un rapprochement entre philosophie logique et sémantique linguistique permet de généraliser la solution strawsonienne: ?une part, on peut traiter simultanément le cas de la predication monadique et celui des relations dyadiques; ?autre part et surtout, la cause profonde de (...) ľasymetrie ainsi généralisée semble se trouver dans une autre asymétrie que ľauteur identifie sous le nom ? asymétrie quantitative ≪. Ce résultat confirme que, tant en philosophie logique qu'en linguistique, une methode informelle est féconde, et en même temps aussi rigoureuse que la méthode formelle.SummaryBy way of illustrating and clarifying the concept of understanding in the theoretical sense in which to understand something is tantamount to being able to explain it, the author takes up the problem of the asymmetry of subjects and predicates with regard to negation in philosophical logic. How much explanation can we hope achieve in such a field? If we bring to bear on the problem of the asymmetry recent results in linguistic semantics, we get a generalization of P. F. Strawson's proposed solution: an abstract structure is shown to be common to monadic predication and dyadic relations, and the cause of the asymmetry which is characteristic of that structure is identified as a new, probably “quantitative” asymmetry between subjects and predicates. These results contribute to substantiate the case for an informal method, both in philosophical logic and in general linguistics. (shrink)

With fascinating historical anecdotes and incisive scientific analysis, this important work combines ancient thought with modern theory to reveal a new way of viewing our universe that can expand our awareness, our lives, and may well point the way to a new science for the twenty-first century.

One of the goals of a certain brand of philosopher has been to give an account of language and linguistic phenomena by means of showing how sentences are to be translated into a "logically perspicuous notation" (or an "ideal language"—to use passe terminology). The usual reason given by such philosophers for this activity is that such a notational system will somehow illustrate the "logical form" of these sentences. There are many candidates for this notational system: (almost) ordinary first-order predicate logic (...) (see Quine [1960]), higher-order predicate logic (see Parsons [1968, 1970]), intensional logic (see Montague [1969, 1970a, 1970b, 1971]), and transformational grammar (see Harrnan [1971]), to mention some of the more popular ones. I do not propose to discuss the general question of the correctness of this approach to the philosophy of language, nor do I wish to adjudicate among the notational systems mentioned here. Rather, I want to focus on one problem which must be faced by all such systems—a problem that must be discussed before one decides upon a notational system and tries to demontrate that it in fact can account for all linguistic phenomena. The general problem is to determine what we shall allow as linguistic data; in this paper I shall restrict my attention to this general problem as it appears when we try to account for certain words with non-singular reference, in particular, the words that are classified by the count/ mass and sortal/non-sortal distinctions.

This paper responds to the issues raised by D. Chalmers by offering a research direction which is quite radical because of the way in which methodological principles are linked to scientific studies of consciousness. Neuro-phenomenology is the name I use here to designate a quest to marry modern cognitive science and a disciplined approach to human experience, thereby placing myself in the lineage of the continental tradition of Phenomenology. My claim is that the so-called hard problem that animates these Special (...) Issues can only be addressed productively by gathering a research community armed with new pragmatic tools for the development of a science of consciousness. I will claim that no piecemeal empirical correlates, nor purely theoretical principles, will really help us at this stage. We need to turn to a systematic exploration of the only link between mind and consciousness that seems both obvious and natural: the structure of human experience itself. In what follows I motivate my choice by briefly examining the current debate about consciousness at the light of Chalmer’s hard problem. Next, I outline the phenomenological strategy. Finally I conclude by discussing some of the main difficulties and consequences of this strategy. (shrink)

Timothy Williamson, in various places, has put forward an argument that is supposed to show that denying bivalence is absurd. This paper is an examination of the logical force of this argument, which is found wanting.

This is a first attempt at the philosophical articulation and projection of the Igbo concept of law and the role of law in the traditional environment. In the Igbo traditional setting, the rules of law are uncodified. The author, who teaches philosophy of law and logic at the University of Nigeria, defines the law of a given community as the body of rules recognised as binding by its members. On this concept of law, he has based his attempt to elucidate (...) the philosophical underpinning of those rules recognised in Igbo traditional legal system as law. Unless the philosphical foundation is understood, the traditional law, machinery for enforcement, and legislative and judicial processes may appear incomprehensible. The first part gives a descriptive insight into the moral, religious, socio-political and legal background of the Igbo. The second part is devoted to the fundamental questions concerning the concept of law, the various types of laws, the reciprocal influence between law and Igbo religion and the end of laws. Finally, the author examines the nature of right in Igbo traditional thought and locates the philosophical background. (shrink)

We maximally extend the quantum‐mechanical results of Muller and Saunders ( 2008 ) establishing the ‘weak discernibility’ of an arbitrary number of similar fermions in finite‐dimensional Hilbert spaces. This confutes the currently dominant view that ( A ) the quantum‐mechanical description of similar particles conflicts with Leibniz’s Principle of the Identity of Indiscernibles (PII); and that ( B ) the only way to save PII is by adopting some heavy metaphysical notion such as Scotusian haecceitas or Adamsian primitive thisness. We (...) take sides with Muller and Saunders ( 2008 ) against this currently dominant view, which has been expounded and defended by many. *Received July 2008; revised May 2009. †To contact the authors, please write to: F.

: A major shortcoming of the Animal Welfare Act is its exclusion of the species most-used in experimentation-rats, mice, and birds. Considerations of justice dictate that extension of the law to these three species is the morally right thing to do. A brief history of how these species came to be excluded from the laws protecting laboratory animals is also provided, as well as discussion of the implications and significance of expanding the law.

The globalization in business and tourism becomes crucial more and more for the economical sustainability of local communities. In the presence of an epidemic outbreak, there must be such a decision on the policy by the host community as whether to accept visitors or not, the number of acceptable visitors, or the condition for acceptable visitors. Making use of an SIRI type of mathematical model, we consider the influence of visitors on the spread of a reinfectious disease in a community, (...) especially assuming that a certain proportion of accepted visitors are immune. The reinfectivity of disease here means that the immunity gained by either vaccination or recovery is imperfect. With the mathematical results obtained by our analysis on the model for such an epidemic dynamics of resident and visitor populations, we find that the acceptance of visitors could have a significant influence on the disease’s endemicity in the community, either suppressive or supportive.

An alternative semantic framework is proposed in the following to reconstruct and make sense of “Eastern logics”: a Question-Answer Semantics (thereafter: QAS), including a set of questions-answers and a finite number of ensuing non-Fregean logical values. Thus, meaning is provided by yes-no answers to corresponding questions about relevant properties. These logical values help to show that the saptabhaṅgī (and its dual, viz., the Buddhist Mādhyamaka catuṣkoṭi) is not a many-valued paraconsistent logic but, rather, a one-valued proto-logic: a constructive machinery that (...) serves as a formal theory of judgment, rather than a Tarskian-like theory of consequence. Such an explanatory model of contradiction assumes a deep redefinition of logical values. (shrink)

Looks at similarities between Eastern philosophy and Western physics, the connection between cell communicatioin and the immune system, and linguistic properties of the genetic code.

Laboratory animals, being vulnerable subjects, need the protection provided by adequate ethical review. This review falls primarily to Institutional Animal Care and Use Committees. A review committee's first duty is to identify which procedures ethically are unacceptable irrespective of any knowledge that might be derived. Examples are provided. These projects should be disapproved. Then, "on balance" judgments are assessed that weigh the animal harms against the potential benefits to humans. Several countries (but not the United States) use a classification system (...) for ranking the degree of animal pain and distress. This type of assessment is essential for careful ethical analysis. Another way to enhance ethical discussion is to strive for a more balanced perspective of different viewpoints among members of decision making committees. Inclusion of representatives of animal welfare organizations and a greater proportion on nonanimal researchers would likely achieve this objective. (shrink)

We develop a bottom-up approach to truth-value semantics for classical logic of partial terms based on equality and apply it to prove the conservativity of the addition of partial description and selection functions, independently of any strictness assumption.

Context: The advent of a general artificial intelligence mechanism that learns like humans do would represent the realization of an old and major dream of science. It could be achieved by an artifact able to develop its own cognitive structures following constructivist principles. However, there is a large distance between the descriptions of the intelligence made by constructivist theories and the mechanisms that currently exist. Problem: The constructivist conception of intelligence is very powerful for explaining how cognitive development takes place. (...) However, until now, no computational model has successfully demonstrated the underlying mechanisms necessary to realize it. In other words, the artificial intelligence (AI) community has not been able to give rise to a system that convincingly implements the principles of intelligence as postulated by constructivism, and that is also capable of dealing with complex environments. Results: This paper presents the constructivist anticipatory learning mechanism (CALM), an agent learning mechanism based on the constructivist approach of AI. It is designed to deal dynamically and interactively with environments that are at the same time partially deterministic and partially observable. CALM can model the regularities experienced in the interaction with the environment, on the sensorimotor level as well, as by constructing abstract or high-level representational concepts. The created model provides the knowledge necessary to generate the agent behavior. The paper also presents the coupled agent environment system (CAES) meta-architecture, which defines a conception of an autonomous agent, situated in the environment, embodied and intrinsically motivated. Implications: The paper can be seen as a step towards a computational implementation of constructivist principles, on the one hand suggesting a further perspective of this refreshing movement on the AI field (which is still too steeped in a behaviorist influence and dominated by probabilistic models and narrow applied approaches), and on the other hand bringing some abstract descriptions of the cognitive process into a more concrete dimension, in the form of algorithms. Constructivist content: The connection of this paper with constructivism is the proposal of a computational and formally described mechanism that implements important aspects of the subjective process of knowledge construction based on key ideas proposed by constructivist theories.

The last decades have shown that Nicander'sTheriaca(second centuryb.c.e.), a didactic hexameter poem of 958 lines on snakes, scorpions, spiders, and the proper treatment of the wounds they inflict, is a markedly more playful work than most readers thought. Rather than considering the poem as a vehicle of authentic learning, literary approaches to the nature of Nicander's strange poetic world have focussed on his eye for Alexandrian aesthetics, intertextuality, linguistic innovation, and awareness of the didactic tradition that started with Hesiod'sWorks and (...) Days, but also on his predilection for horror, voyeuristic sensationalism, and gory details. Although literary-minded readers have found it hard to disprove convincingly that Nicander may have hadsomeprofessional knowledge of his subject matter, a glance at his arcane language is enough to convince any reader that theTheriacacannot be concernedsolelywith its explicit subject. In this article I will make some additional observations on the way in which Nicander has turned theTheriacainto a work of literature, focussing on some of the choices that he has made with regard to his less than veracious depiction of snakes and animals. While Spatafora rightly points to Nicander's eye for detail when portraying floral beauty, I will argue that the poet's play with thetoposof thelocus amoenushas a darker side. Rather than creating an epic world of beauty, Nicander shows his talent for taking the reader along an unpleasant path of apprehension and negative feelings, portraying a choice selection of afflictions. Not only does he have many ways of giving his quasi-scientific account a markedly negative atmosphere, but his world may well be a deliberate reversal of that other well-known Hellenistic portrayal of the natural world, Theocritus' bucolics.

In his milestone textbook Lattice Theory, Garrett Birkhoff challenged his readers to develop a "common abstraction" that includes Boolean algebras and lattice-ordered groups as special cases. In this paper, after reviewing the past attempts to solve the problem, we provide our own answer by selecting as common generalization of ������������ and ������������ their join ������������∨������������ in the lattice of subvarieties of ������ℒ (the variety of FL-algebras); we argue that such a solution is optimal under several respects and we give an (...) explicit equational basis for ������������∨������������ relative to ������ℒ. Finally, we prove a Holland-type representation theorem for a variety of FL-algebras containing ������������∨������������. (shrink)

La «question de l'Inconditionné» est développée par Paul Tillich dans une Religionsphilosophie pensée comme Logique de la raison religieuse et comme Théorie du sens, dans une perspective théonome. La présente étude analyse le projet du premier Tillich, après l'avoir situé en relation au paradigme de la Modernité. Tillich mène un double combat, face à l'«hybris religieuse» de l'hétéronomie et à l'«hybris culturelle» de la pure autonomie. Partant de la tension fondamentale entre identité mystique et différence éthique, le projet de Tillich (...) souligne l'aspect paradoxal et dialectique de la religion, son vouloir d'atteindre le contenu inconditionné à travers des formes conditionnées, sa résistance à être pur objet et concept d'une science. Dépassant le paradigme de la Modernité, Tillich construit une Philosophie de la Religion située dans le système des sciences, mais non fondée sur le conditionné, mais au contraire sur l'Inconditionné. Les éléments et catégories du religieux sont soumis à l'analyse à travers un processus méthodologique complexe, critique et dialectique, intuitif et vital; est ainsi formulée l'unité de sens entre le fondé, le fondant et le fondement ultime qui soutient tout. La dialectique du sacré et du profane, du divin et du démoniaque, de la foi et de l'incrédulité, de Dieu et du monde, est éclairée dans la perspective théonome; d'où est surpassée la pure autonomie, en lutte avec l'hétéronomie religieus.
