A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein's famous E = mc² . The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

The democratic principle in its extreme form is the assertation that the mere fact of free birth is alone sufficient to constitute a claim to all offices. It is never the claim of a majority to rule, but it is the demand that every one, whether rich or poor, high- or low-born, shall be equally represented in the constitution. This is what Aristotle calls the principle of numerical equality.-from "Chapter VI: Democracy"One of the most renowned classical scholars of the turn (...) of the 20th century here offers a lucid and highly readable overview of a difficult and little understood aspect of Greek history: its public law, not just how it was structured but how it behaved in action. This 1896 book-perfect for university students, amateur historians, and readers of the history of the law-covers the full range of Greek legal development, from the origin of the city-state and the beginnings of the Greek monarchy to the social and political institutions of the far-flung Greek civilization to the rise of federalism and its long-term historical impact on the cultures that came after.British classical scholar A.H.J. GREENIDGE was a lecturer in ancient history at Brasenose College, Oxford. He is also the author of Roman Public and Private Law (1894), Legal Procedure in Cicero's Time (1901), and Roman Public Life (1901), among many other works of ancient history. (shrink)

An increasingly number of patients in Western civilizations suffer from weak authenticity structure which is characterized by a lack of self-realization, autonomy, character strength, stereotype behavior, inability to use (internal) dialogue in order to learn about oneself and defining oneself as a individual, and so on. In this paper a theoretical model of fragile authenticity structure and some suggestions to regain a more authentic attitude are presented.

The language $L_A$ is formed by adding the quantifier $\Finv x$ , "few x", to the infinitary logic L A on an admissible set A. A complete axiomatization is obtained for models whose universe is the set of ordinals of A and where $\Finv x$ is interpreted as there exist A-finitely many x. For well-behaved A, every consistent sentence has a model with an A-recursive diagram. A principal tool is forcing for $L_A$.

The degree of justification for a judgment of artistic value is normally directly proportional to the size of the comparison class that is brought to bear in making that judgment. If that comparison class is very small or nonexistent, justified judgments are unlikely or impossible. So which artworks, if any, are comparable? The claim that evaluative comparisons can be made among artworks within a fine-grained category—abstract expressionist paintings, for example—is relatively uncontroversial. But is there any way that we can compare (...) artworks that have only a very coarse-grained category in common (such as two works of visual art), or that are in completely different coarse-grained categories (such as a symphony and a sculpture)? I argue that both very similar and very different artworks can be compared evaluatively. Comparisons within fine-grained categories are common, and reflection on critical practices shows us that they depend crucially on qualitative assessments of artistically valuable properties. Once qualitative assessment is recognized as underwriting artistic criticism, it follows that even rough-grained categorization provides no essential barrier to comparison, securing the possibility of well-justified evaluations of disparate artworks.

L'auteur distingue entre la vérité constatante et la vérité vécue. Ces deux vérités sont qualitativement distinctes, et elles sont des ennemies archanées, dès qu'elles se trouvent en présence l'une de l'autre. De nos jours elles se combattent sous les noms de rationalisme et antirationalisme. Pourtant elles peuvent sans aucun compromis se transformer en une synthèse. Et cette synthèse se réalise lorsque la vérité constatante aboutit à sa suprême subtilité: l'observation introspective d'idées à tendance universelle (cette observation s'exprime en définitions exactes) (...) et l'introspection du mouvement de ces idées (qui s'exprime en logique exacte). Cette ultime introspection est la tâche de la philosophie. Le sens véritable de la philosophie est donc d'invoquer logiquement l'intuition postlogique. Cette intuition succède nécessairement à la pure logique philosophique et révèle aussi la valeur universelle des idées logiques par une rétrospection clarifiaǹte. (shrink)
