Plant succession is a phenomenon ascribed to vegetation dynamics at the scale of the plant community. The study of plant succession implies the analysis of the species involved and their relationships. Depending on the research done, the characteristics of trees have been studied according to either static, dimensional or partial approaches. We have revised the principal theories of succession, the methods of describing structure and development of tree and relationship established between tree species' attributes and their successional status. During studies (...) of succession, we propose that the profile of plant species be completed by including the organizational attributes of their structure as well as their development dynamics. We suggest an approach to the architecture that gives a general overview of the mode of development, revealing, among other things, that a limited number of architectural models may be found in nature. We hypothesize that community dynamics, in succession, may to a certain degree arise from the dynamic nature of plant development. This line of reasoning is in accordance with the current school of thought on process structuralism. (shrink)
Research in modern biology has largely been developed according to two main ways of inquiry, as they were outlined by Charles Darwin and Claude Bernard. Each stands for a specific approach to the living corresponding to two different methodological rules: the principle of natural selection and the principle of causation.
In this article I confront Jürgen Habermas' deliberative model of democracy with Claude Lefort's analysis of democracy as a regime in which the locus of power remains an empty place. This confrontation reveals several structural similarities between the two authors and explains how the proceduralization of popular sovereignty provides a discourse-theoretical interpretation of the empty place of power. At the same time, Lefort's insistence on the open-ended nature of the democratic struggle also points towards an unresolved tension at the (...) core of Habermas' model between the cognitive nature of deliberation on the one hand and the freedom of moral and political agents on the other. A proper solution of this tension requires a full appreciation of the ineliminable gap between actual and ideal deliberation. Because actual deliberation can never result in an ideal consensus, the actual exercise of democratic power should be understood as an unavoidable interruption of deliberation. Key Words: consensus • deliberation • democracy • empty place of power • Jürgen Habermas • Claude Lefort. (shrink)
: Convinced that logic has a history and that its history always manages to surprise the philosophers, Claude Imbert has devoted much of her work to the study of the Stoic school and of the late-nineteenth-century German logician Gottlob Frege. In the fifth chapter of her book Pour une histoire de la logique, she examines the trajectory of Frege's awareness of what his new logic entails, in particular the way it subverts the project of Kant.
Claude Bernard, the father of scientific physiology, believed that if medicine was to become truly scientiifc, it would have to be based on rigorous and controlled animal experiments. Bernard instituted a paradigm which has shaped physiological practice for most of the twentieth century. ln this paper we examine how Bernards commitment to hypothetico-deductivism and determinism led to (a) his rejection of the theory of evolution; (b) his minima/ization of the role of clinical medicine and epidemiological studies; and (c) his (...) conclusion that experiments on nonhuman animals were, "entirely conclusive for the toxicology and hygiene of man". We examine some negative consequences of Bernardianism for twentieth century medicine, and argue that physio/ogy's continued adherence to Bernardianism has caused it to diverge from the other biological sciences which have become increasingly infused with evolutionary theory.

The article deals with the question of persuasion by comparing two passages taken from a text written by Victor Hugo entitled Claude Gueux The first passage is taken from the first part of the text in which Hugo tells the story of the murder of the director of the Clairvaux prison workshop perpetrated by a prisoner, Claude Gueux, followed by the latter’s trial and execution. The second passage studied is taken from the second part of the text in (...) which Hugo argues against the death penalty. This article begins with an intuitive sense that the styles of these passages are “different”: the second one clearly shows Hugo’s persuasive intention, which is to say his effort to make his position be accepted. That said, does this extract have semantic properties that the descriptive passage does not have? The hypothesis advanced is that the organization of contents is of a similar nature in both passages of Claude Gueux and that it is only in an enunciative way that the passages are distinguishable. This enunciative difference allows the militant passage’s locutor to portray himself in a favorable light and, herewith, to convince the reader to his point of view. It is, hence, but in an indirect manner that Hugo’s persuasive intention appears; as it is without a semantic mark. (shrink)
Claude Bernard's concept of the internal environment ( milieu intérieur ) played a crucial role in the development of experimental physiology and the specific medical therapeutics derived from it. This concept allowed the experimentalist to approach the organism as fully determined yet relatively autonomous with respect to its external environment. However, Bernard's theory of knowledge required that he find organismic functioning as the result of an external necessity. He is therefore unable to explain adequately the origin or operation of (...) organismic autonomy. A more complete conception of biological autonomy must include a theory of knowledge that can accommodate the organism as a source of discrimination and determination. Only in this way will it be possible to see organisms as active as well as reactive, as ordering as well as ordered. This shift in perspective is crucial if medicine is to be able to characterize, for example, susceptibility to disease. A cognitive sense of the organic interior is proposed as an alternative to Bernard's internal environment.

This study is devoted to the problem of the place and significance of the scientific quest and worldview, and to their articulation with metaphysics as they serve to bring the mind to the consideration of the problem and mystery of the existence of God in the thought of the contemporary French philosopher and theologian Claude Tresmontant (1925-97).
