A social scientific survey on visions of human/nature relationships in western Europe shows that the public clearly distinguishes not only between anthropocentrism and ecocentrism, but also between two nonanthropocentric types of thought, which may be called “partnership with nature” and “participation in nature.” In addition, the respondents distinguish a form of human/nature relationship that is allied to traditional stewardship but has a more ecocentric content, labeled here as “guardianship of nature.” Further analysis shows that the general public does not subscribe (...) to an ethic of “mastery over nature.” Instead, practically all respondents embrace the image of guardianship, while the more radical relationships of partnership and participation also received significant levels of adherence. The results imply that ethicists should no longer assume that the ethics of the public are merely anthropocentric. Finally, they call into question the idea of a single form of ecocentrism and favor a hermeneutic virtue ethics approach to the study of the interface between ethics and action. (shrink)
La pensée fondamentale de Wittgenstein affirme que les constantes logiques ne représentent pas, ne fonctionnent pas sémantiquement comme des noms. En apparence truiviale, cette pensée, nous le montrerons, à des ramifications étonnantes dans la philosophie du premier wittgenstein, en ce qui concerne partmulzer sa conception de la logique. Notre but est d'interpréter l'aphorisme en question (T 4.0312) en montrant comment il se rapporte aux thèses et théories les plus importantes du Tractatus, et comment il permet de les faire tenir ensemble (...) d'une façon cohérente, justifiant par là son caractère "fondamental". Nous tentons également d'apporter une réponse aux questions suivantes: les propositions complexes sont-elles encore — comme les propositions atomiques — des "images" de la réalité? et quelle est cette "logique des faits" dont parle Wittgenstein dans l'aphorisme sous examen?

Nous clarifions et critiquons un argument influent opposé au déflationnisme par [Shapiro 1998b] et [Ketland 1999], fondé sur la non-conservativité des extensions des théories formalisées par des principes aléthiques universellement admis. À cette interprétation anti-déflationniste des phénomènes de non-conservativité, nous en opposons une autre, compatible à la fois avec les faits logiques et les thèses déflationnistes.
The best way to predict the future is to invent it. —Alan Kay_1_
It is obvious that there are patterns of cultural change—evolution in the neutral sense—and any theory of cultural change worth more than a moment's consideration will have to be Darwinian in the minimal sense of being consistent with the theory of evolution by natural selection of Homo sapiens. —Daniel Dennett_2_
The future is here. It's just not widely distributed (...) yet. —William Gibson_3_
It is the magician's wand, by means of which he may summon into life whatever form and mould he pleases. —Charles Darwin commenting on the power of artificial selection_4_
This article introduces an applied Theory of Evolution of Artificial Systems, called Directed Evolution (DE). The theory is grounded in fifty years of research on Inventive Engineering known as TRIZ, which started in the former Soviet Union by G. Altshuller and continues today. The theory has generated a set of Patterns and Lines of Evolution that represent a compilation of trends that document strong, historically recurring tendencies in the development of manmade systems in general and technological systems in particular. Directed Evolution is the systematic applied-oriented process for “predicting” future generations of a system by inventing them along these evolutionary patterns. The current article introduces the theory, reflects on its basic underlying logic, and provides a broad historical context and intellectual justification for such an effort. It shows that the quest of DE theory and practice falls well within the boundaries of past pursuits to identify evolutionary patterns of complex systems and to use these patterns to control and manipulate possible futures of artificial systems.

It is a wel known fact that the finite products of Hintikka-Fraissé types for sentences of quantifier rank n give rise to the set of atoms of a finite boolean algebra. In this paper we consider the class of (Lww)t-types introduced in [4], which caracterizes in a pure topological way the (Lww)t-equivalence for T3 spaces. We define for every nonempty family I of n-types a product xInai in such a way that if I is a family of T3 spaces, XIAi (...) denotes its product with the box topology and (ai)1ε XIAi we have that if the n-type of ai is ai (i ε I), then the n-type of (ai)I is xInai. We then prove that, for every n ≥ 1, it is possible to define a lineal order nI of satisfiable n-types and every J c I, we have xJαj ≤nxlnαi. We also prove that these results for Ziegler’s typescan be generalized, if we consider the class of (Lω1ω)t-types introduced in [6], which permits to characterize the (Lω1ω)t-equivalence for a wide class of T3 spaces.

The historian Agathias (Hist. II 30.3-31.4) relates that under the Emperor Justinian seven philosophers (Damascius, Simplicius, Eulamius, Priscianus, Hermeias, Diogenes, and Isidorus) sought refuge in Persia because of their own country's anti-pagan laws but that they ultimately returned in 532 to the Roman Empire. There have been many hypotheses about the fate of these philosophers after their return. Most recently M. Tardieu has argued that these philosophers went to Harran, a town that was located on the Persian frontier and that (...) remained mostly pagan until the tenth century. This hypothesis, which M. Tardieu had backed with a number of arguments, has found many echoes, both positive and negative, in subsequent secondary literature. Yet the complexity of the issue has never really been faced by Tardieu's critics. For example, the fact that, according to Arab sources, Simplicius could found a famous school of mathematics has been completely neglected, as has the fact that details of the dogmas of Manicheanism, which he obtained through his encounter with a member of that sect, enable one to envision a Mesopotamian locale for this encounter. The present study aims at taking stock of the elements of this controversy, beginning with a detailed article by D. Watts and a review by C. Luna. Watts mostly bases his criticisms of M. Tardieu and me on Luna's summary. In the conclusion (pages 58-59), I summarize the main points that seem to me to confirm M. Tardieu's hypothesis. (shrink)
Concerning the book by R. Arnzen Abū l-'Abbās an-Nayrīzīs Exzerpte aus (Ps.-?) Simplicius' Kommentar zu den Definitionen, Postulaten und Axiomen in Euclids Elementa I, the present paper offers a survey of the way the late Neoplatonists used to conceive and compose their commentaries. Far from trying to be original, each commentary is largely based on the works of predecessors.
