Bringing together evolutionary biology, psychology, and philosophy, Henry Plotkin presents a new science of knowledge, one that traces an unbreakable link between instinct and our ability to know.

In their environment, plants are continuously submitted to natural stimuli such as wind, rain, temperature changes, wounding, etc. These signals induce a cascade of events which lead to metabolic and morphogenetic responses. In this paper the different steps are described and discussed starting from the reception of the signal by a plant organ to the final morphogenetic response. In our laboratory two plants are studied: Bryonia dioica for which rubbing the internode results in reduced elongation and enhanced radial expansion and (...) Bidens pilosa for which the response occurs at distance, hence pricking the cotyledon of a plantlet induces the growth inhibition of both the hypocotyl and the axillary bud of the pricked cotyledon. Reception of the signal and transmission of the message. In Bryonia the signal is received by epidermal cells while in Bidens they are the cells adjacent to the midrib of the cotyledon which receive the mechanical signal. In both plants the message is transmitted via a wave of electric depolarization. This latter is composed of an action potential associated with a slow wave whose transmission rates are respectively 1cm s−1 and 1 mm s−1. Recent results have shown the involvement of Ca2+ in the triggering of the slow wave and the role of the H+ pump during the slow wave. Transient and fast biochemical responses. An entry of extraceilular Ca2+ into the cells and a transient increase in IP3 occur within seconds following the mechanical stimulus. At the same time, the membrane becomes more fluid, correlated with qualitative changes in phospholipids. The rapid increase in the concentration of peroxidated lipids may be correlated with ethylene biosynthesis which is stimulated after rubbing. Other parameters such as cytoplasmic pH, relative water content, hydric potential, membrane potential and modifications of K+, Mg2+-ATPase and Ca2+-ATPase activities, play a key role in the early responses induced by the traumatisms. Irreversible-biochemical responses. The mechanical stimulus performed on a Bryonia internode induces an acceleration of: i) enzymatic activities related to the lignification, ii) esterification of phenolic acids in the cell wall. Consequently the lignification process is accelerated. Storage of the information. After being received by the target cells the information can be stored during several days before being expressed. At the level of cotyledonary bud, the first message, previously stored, can be expressed or not by a second treatment. Bidens thus behaves as if it was able to “store” and to “retrieve” morphogenetic messages, using a sort of rudimentary memory. The nuclei of the bud cells of the pricked cotyledon show that these cells, initially in G2 phase, divide and then remain in the G1 phase. In Bryonia, calli derived from young stimulated internodes, keep thigmomorphogenetic characteristics during several weeks. In the last part of this paper the particularity of our plant model which permits a study of the transmission and storage of the message, is underlined. The links between the different steps induced by the stimulus are discussed. Special attention is devoted to second messengers and to the amplification of the message. (shrink)

Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the work, influences and legacy of the Nobel Prize physicist and philosopher of experiment Niels Bohr. While covering Bohr's groundbreaking contribution to quantum mechanics, this collection reveals the philosophers who influenced his work. Linking him to the pragmatist C.I. Lewis and the Danish philosopher Harald Høffding, it draws strong similarities between Bohr's philosophy and the Kantian way of thinking. Addressing the importance of Bohr's views of classical concepts, it discusses how (...) his interpretation of quantum mechanics now compares with a variety of issues that have arisen only since his lifetime, including decoherence and other non-collapse arguments. Balancing historical themes with contemporary ideas, Niels Bohrs and Philosophy of Physics reveals Bohr's on-going contribution to the philosophy of science and confirms his place in the history of philosophy.

This paper explores the relation between personal identity and story telling. In particular l examine how Paul Ricoeur links narrative discourse to identity formation. For Ricoeur stories are not simply aesthetic objects disconnected from experience, but are rooted in the very fabric of life and have the capacity to profoundly refigure our world. Narrative discourse and life are for Ricoeur dialcetically tied to each other through a “mimetic arc.” This, however, poses interesting problems and difficulties. How do stories affect the (...) transformation of experience? According to Ricoeur the identity of the text can be incorporated into my own personal and communal identity through a mode of analogical transfer. This is the art of interpretation, the art of selfhood, the performative process of becoming a self in relationship with others.Cet artiele analyse la relation entre identité personnelle et le fait de raconter une histoire. J’aborde en partieulier le lien entre le discours narratif et la formation identitaire, tel que le conçoit Ricoeur. Pour ce dernier, les histoires ne sont pas simplement des objets esthétiques détachés de I’experience; elles sont plutôt ancrées dans le tissu même de la vie, et ont le pouvoir de refigurer profondément notre monde.Le discours narratif et la vie sont, dans la pensée de Ricoeur, liés defaçon dialectique par un «arc mimétique». Une telle façon de voir soulève, cependant, des questions et des difficultés interéssantes. Comment les histoires affectent-elles la transformation de l’expérience? Selon Ricoeur, l’identite du texte peut être intégrée dans ma propre identité personnelle et collective par un mode de transfert analogique. C’est en cela que consiste l’art de I’interprétation, de l’ipséité, le proeessus performatif du devenir de soi en relation avec les autres. (shrink)

Ce n'est que tard dans sa vie que Wilhelm von Humboldt a donné au concept de « forme de la langue » son nom et sa définition. Ce qui est réellement nouveau dans cette conception, par rapport à ses analyses plus anciennes, c'est que, à côté de sa fonction régulatrice en linguistique, elle correspond chez Humboldt à une affirmation accrue de l'unité et de l'autonomie de chacune des langues. Une langue n'est pas l'émanation d'une nation donnée ; c'est un être, (...) pas un simple phénomène. Cela ne veut pas dire que les langues auront toutes la même valeur spirituelle, ni que l'individu sera prisonnier de la langue ; mais, dans son chemin vers la reconnaissance de cet être de la langue, Humboldt prend le risque de rouvrir le dualisme qu'il voulait fermer. Tout spécialement quand la « forme interne de la langue » évoque quelque sujet spirituel qui se servirait des outils grammaticaux et lexicaux. Cela ne veut pas dire que les langues auront toutes la même valeur spirituelle, ni que l'individu sera prisonnier de la langue ; mais, dans son chemin vers la reconnaissance de cet être de la langue, Humboldt prend le risque de rouvrir le dualisme qu'il voulait fermer. Tout spécialement quand la « forme interne de la langue » évoque quelque sujet spirituel qui se servirait des outils grammaticaux et lexicaux. Wilhelm von Humboldt gave the concept of « form of language » a name and a definition only late in his life. What is really new in this conception, in comparison to his older ones, is that, besides its regulative fonction for the linguist, it has to be linked to a stronger emphasis put by Humboldt on both unity and autonomy of every language. A language is not only the émanation of a certain nation ; it is a being, not only a phenomenon. This does not mean that all languages will have the same spiritual worth. It does not either mean that the individual will be some prisoner of the language ; but in his path towards the recognition of the being of the language Humboldt runs the risk of breaking open the dualism he wanted to heal up. Especially when the « inner form of the language » calls up some spiritual subject using both grammatical and lexical tools. (shrink)

This volume of essays examines the problem of mind, looking at how the problem has appeared to neuroscientists from classical antiquity through to contemporary times. Beginning with a look at ventricular neuropsychology in antiquity, this book goes on to look at Spinozan ideas on the links between mind and body, Thomas Willis and the foundation of Neurology, Hooke’s mechanical model of the mind and Joseph Priestley’s approach to the mind-body problem. The volume offers a chapter on the 19th century Ottoman (...) perspective on western thinking. Further chapters trace the work of nineteenth century scholars including George Henry Lewes, Herbert Spencer and Emil du Bois-Reymond. The book covers significant work from the twentieth century, including an examination of Alfred North Whitehead and the history of consciousness, and particular attention is given to the development of quantum consciousness. Chapters on slavery and the self and the development of an understanding of Dualism bring this examination up to date on the latest 21st century work in the field. At the heart of this book is the matter of how we define the problem of consciousness itself: has there been any progress in our understanding of the working of mind and brain? This work at the interface between science and the humanities will appeal to experts from across many fields who wish to develop their understanding of the problem of consciousness, including scholars of Neuroscience, Behavioural Science and the History of Science.

This paper defends a realist interpretation of theories and a modest realism concerning the existence of quantities as providing the best account both of the logic of quantity concepts and of scientific measurement practices. Various operationist analyses of measurement are shown to be inadequate accounts of measurement practices used by scientists. We argue, furthermore, that appeals to implicit definitions to provide meaning for theoretical terms over and above operational definitions fail because implicit definitions cannot generate the requisite descriptive content. The (...) special case of establishing a temperature scale is examined to show that nonrealist accounts fail to provide insight into the theoretical connections that scientific laws postulate to hold among quantities.

The rapid emergence of digital media has created both new economic opportunities and new risks for authors, publishers, and users in regards to intellectual property. There is a theoretical conflict raging between those who believe "information should be free" and those attempting to protect intellectual property through surveillance and control of access. The Intellectual Commons works to develop a theory of intellectual property that is based on a theory of natural rights that assumes the existence of a "natural world" of (...) intellectual resources.

1. Introduction. Professor Nagel's account of the “cognitive status” of scientific theories has been attacked by P. K. Feyerabend [5] and M. B. Hesse [8] in terms of his alledgedly misguided distinction between experimental laws and theories. The difficulty lies, these critics agree, in Nagel's attempt to find a stable basis for scientific theories in an observational basis of experimental laws. Both Feyerabend and Hesse note the vacillation in Nagel's account of the stability of the meaning of experimental terms and (...) in his discussion of the status of observational as opposed to theoretical terms. They find Nagel too “positivistic” and see as a first step toward a more adequate account of scientific theories the abandonment of the theoretical-observational dichotomy as having more than a pragmatic significance. Nagel's discussion of the theoretical-observational dichotomy is, I agree, inadequate in certain respects. I shall, however, suggest a quite different remedy from those of Feyerabend and Hesse, one that depends neither on a phenomenalistic reduction of theoretical entities nor on a blurring of the theoretical-observational dichotomy.

What explains the continuing hardship of so many black Americans? A distinguished group of scholars analyzes the long, complex structural and environmental causes of discrimination and their effects on African-Americans. The authors examine the impact of poverty, poor health, poor schools, poor housing, poor neighborhoods, and few job opportunities—and demonstrate how multiple causes reinforce each other and condemn African-Americans to positions of inferiority and poverty. Some of the contributors examine policies designed to correct problems, while others look at the changing (...) racial and ethnic composition in America and its implications for African-Americans, as other minorities surpass them in numbers and claim political, economic, and social attention. The late James Tobin has contributed a foreword to this important collection. (shrink)

Abstract: The optimum definition of the term "genocide" has been hotly contested almost since the term was coined. Definitional boundaries determine which acts are covered and excluded and thus to a great extent which cases will benefit from international attention, intervention, prosecution, and reparation. The extensive legal, political, and scholarly discussions prior to this article have typically (1) assumed "genocide" to be a fixed social object and attempted to define it as precisely as possible or (2) assumed the need for (...) a fixed convention and sought to stipulate the range of events that should be denoted by the term. Even if its meaning is a matter of convention, however, "genocide" is not a fixed object but varies by context and evolves in methods and forms over time. In fact, as relevant laws, legal interpretations, and political commitments develop, so do would-be perpetrators modify what genocide is in order to avoid political and legal consequences. This article advances an approach to a definition of "genocide" that allows even legal definitions to keep pace with this evolutionary process. (shrink)

This study provides an evaluation of ethical business perception of busIness students from three countries: Australia, Taiwan and the United States. Although statistically significant differences do exist there is significant agreement with the way students perceive ethical/unethical practices in business. The findings of this paper indicate a universality of business ethical perceptions.

: Once cast aside as of no value, Charles S. Peirce manuscript 1570 "The First of Six Lessons . . ." and its context, provides uniquely valuable access to Peirce's religious practice (as distinct from his theology). Chronically unemployed, Peirce seized an opportunity to put in a bid for a vacant post in elocution at the Episcopal Church's major (and only "official") theological seminary, The General Theological Seminary in New York City. Peirce had on occasion appealed to nearby members of (...) the Episcopalian hierarchy seeking patronage for his scholarly work—to no avail. In this case, however, he was encouraged and aided by the current scholarly vicar of his own parish. The incumbent had pursued advanced education abroad and was also active in the seminary's affairs. And, of course, Peirce was confident about his expertise in elocution, which "General's" Dean claimed as well. Both the contextual narrative and the substantive theological content of his "lesson" are a rich resource for insights into the much vexed (if too often muddled) question of his lifelong commitment to a faith stemming from his earlier conversion to trinitarianism.

Beginning from the standpoint that technologically mediated education is widely prescribed for developing countries, the author first probes the nature, meaning, and impact of this agenda through its economic and political context. He argues that this context produces and shapes the rush to technology. He then examines the notion of education and the nature of the claimed technological mediation of this process, concluding that the constraints of technological mediation, and its destructive impact on teaching, show its inability to provide for (...) adequate educational development (which is necessarily grounded in a concrete human relationship in a real—not virtual—dynamic social and cultural context). He closes with recommendations for a critical rather than a wholesale adoption of technology and encourages resistance to the present press for mindless adoption. (shrink)
