In the present note we give a direct deduction of the Axiom of Choice from the Maximal Ideal Theorem for commutative rings with unit.

It is shown in Zermelo-Fraenkel Set Theory that Cκ, the Axiom of Choice for κ-indexed families of arbitrary sets, is equivalent to the condition that the frame envelope of any κ-frame is κ-Lindelöf, for any cardinal κ.

It is shown for an arbitrary topos that the Law of the Excluded Middle holds in its propositional logic iff it satisfies the limited choice principle that every epimorphism from 2 = 1 ⊕ 1 splits.

This volume introduces a model of the human physical mind that puts the concept of competence at the center of its analysis, constructing a post-positivistic, postmodern and post-analytic philosophy of the human mind that combines empirical-instrumental phenomenology and neo-hermeneutics.

In L’institution, la passivité. Notes de cours au Collège de France (1954-1955), Maurice Merleau-Ponty develops approaches to a concept of the unconscious that can also be relevant to a mental philosophy from the perspective of cognitive science and AI in the tradition of continental philosophy. I consider this all the more important as previous attempts at an analytical philosophy of AI tend to remain stuck in Cartesian or Platonic dualism, which – as a dream of Silicon Valley – could encourage (...) gnostic thinking (Irrgang 2021).

O presente artigo parte da ideia de que o conceito conservativo-conservador de sustentabilidade (das florestas, por exemplo) deve ser combinado com a ideia inovadora do ponto de vista tecnológico-económico de desenvolvimento sustentável de modo a formar uma ideia reguladora de desenvolvimento sustentável de acordo com um modelo aberto. O artigo defende que o desenvolvimento tecnológico pode do ponto de vista cultural e institucional ser organizado de uma forma mais sustentável, muito embora a sustentabilidade não tenha ainda sido alcançada tanto do (...) ponto de vista global como do regional Para o autor do artigo, o conceito de desenvolvimento sustentável não é umo ideologia, muito embora a mera consideração anti-capitalista do problema da protecção do ambiente seja passivel de ser considerada ideológica. Segundo o artigo, a protecção da sobrevivencia não deve ser vista em oposição ao desenvolvimento sustentável, antes sim como um ponto de partida para a busca de estratégias e caminhos de sustentabilidade no desenvolvimento. Uma ética do futuro tampouco constitui modelo unilateral relativo às questões de etica ambiental. Segundo o autor, porém, todos os componentes do modelo de desenvolvimento sustentdvel tornados em conjunto resultam numa heuristica de busca pragmáticamente suficiente e adequada para todo e qualquer processo de desenvolvimento sustentável. /// The conservative-conserving concepts of sustainability (offorestry, f. e.) should be combined with the innovative technological-economical idea of sustainable development to a regulative idea of sustainable development according to an open model. Technological development could institutionally-culturally be organised in a more sustainable way, even though sustainability has neither globally nor regionally been reached yet. The concept of sustainability is no ideology, while a simple anticapitalistic view of the conservation problem appears to be ideological itself. Protection of survival is not to be seen as an opposition to sustainable development, but as a starting point of search-strategies for paths of sustainable development. Future-Ethics is also not an explicit search-pattern for questions of ecological ethics. The combined components of the model of sustainable development result in a pragmatically sufficient Search-Heuristics for sustainable development. (shrink)

Anhand der Bearbeitungen zweier Opernstoffe möchte der Aufsatz zu einer Neubewertung der barocken Opernlibretti anregen. Die enge Verbindung zwischen Musik- und Sprechtheater in der Barockzeit sowie die Veränderungen in bezug auf Affektdarstellung, Rollenspiel, komische Figur und Bühnenbild werden im Hinblick auf den Wandel vom höfischen zum bürgerlichen Normensystem interpretiert. The function of baroque opera libretti is illustrated by comparing different versions of two operatic plots. The close links between musical and spoken drama in the baroque period, as well as the (...) differences in the expression of passions, role-playing, comic characters and stage sets are interpreted in the context of the process in which a courtly set of norms was supplanted by a bourgeois one.
