Within ordinary ---unitary--- quantum mechanics there exist global protocols that allow to verify that no definite event ---an outcome to which a probability can be associated--- occurs. Instead, states that start in a coherent superposition over possible outcomes always remain as a superposition. We show that, when taking into account fundamental errors in measuring length and time intervals, that have been put forward as a consequence of a conjunction of quantum mechanical and general relativity arguments, there are instances in which such global protocols no longer allow to distinguish whether the state is in a superposition or not. All predictions become identical as if one of the outcomes occurs, with probability determined by the state. We use this as a criteria to define events, as put forward in the Montevideo Interpretation of Quantum Mechanics. We analyze in detail the occurrence of events in the paradigmatic case of a particle in a superposition of two different locations. We argue that our approach provides a consistent single-world picture of the universe, thus allowing an economical way out of the limitations imposed by a recent theorem by Frauchiger and Renner showing that having a self-consistent single-world description of the universe is incompatible with quantum theory. In fact, the main observation of this paper may be stated as follows: If quantum mechanics is extended to include gravitational effects to a QG theory, then QG, S, and C are satisfied.

Résumé L’article vise à souligner la signification politique de l’avènement de la Critique kantienne. Pour ce faire, une double thèse est défendue : il y a une matrice juridique sous-jacente au mouvement conceptuel de la philosophie critique, dont la puissance émancipatrice et révolutionnaire se manifeste à la lumière du contexte historique de sa formulation. L’argument se déploie de la façon suivante : une exploration des rapports entre la formule « révolution de la pensée » que l’on trouve dans la Critique de la raison pure et le contexte historique de la publication l’œuvre ; ensuite un examen de la métaphore juridique et la façon dont elle incarne l’idée d’une philosophie critique ; et pour conclure la suggestion d’une hypothèse interprétative d’après laquelle le « contrat originaire » est un opérateur conceptuel accomplissant un mouvement analogue à celui qui est exigé de la philosophie critique : le passage du niveau individuel au niveau intersubjectif.The aim of the article is to highlight the political significance of the advent of Kant’s Critique. In order to establish it, a double thesis is defended: there is a juridical matrix underlying the conceptual movement of the critical philosophy, whose emancipatory and revolutionary strength is revealed in the light of the context of its formulation. The argument will be deployed in the following way: an exploration of the connections between the formula “a revolution in thought” articulated in the Critique and the historical context of its publication; followed by an exam of the juridical metaphor of the Tribunal and the way in which it embodies the idea of a critical philosophy and finally, as a conclusion, the suggestion of an interpretative hypothesis according to which the notion of contract is a conceptual operator accomplishing an analogous movement to the one required from the critical philosophy: the passage from the subjective level to the intersubjective one.

La lectura plotiniana de la sincronicidad entre astros y hechos humanos en vez de la lectura causa-efecto de la astrología judiciaria tradicional fue la visión más seguida por el humanismo. Las estrellas no representan poderes en si mismos sino como símbolos o signos. El hombre sabio, y así lo entendieron también los humanistas neoplatóncios, es aquél que sabe interpretar los símbolos desentrañando el sentido de la simpatía o analogía universales. El poder simbólico, por basarse en una inspiración abierta más que en el raciocinio lógico, entronca con otros lenguajes simbólicos, incluido el de la literatura, al que presta numerosos recursos

La atención al problema de la circulación internacional de las ideas se ha transformado en uno de los rasgos característicos de la renovación de la historia intelectual en los últimos años. La cuestión viene siendo abordada desde distintas perspectivas teóricas que han enriquecido las herramientas metodológicas del campo. Sin embargo, el problema de la "recepción" ha sido un interrogante persistente en culturas como las latinoamericanas que, por su condición "periférica", han enfrentado la experiencia de la traslación de sentidos desde su propia emergencia. Resulta entonces pertinente enriquecer aquellos debates con las sugerencias que desde hace años viene aportando el ensayismo latinoamericano sobre la cuestión. Se abordan aquí distintos autores y discusiones que condensan con especial riqueza las múltiples aristas del problema. Los diferentes casos tratados contribuyen a delinear una concepción eminentemente activa de la recepción como reconfiguración permanente de sentidos, en el marco de una visión no esencialista de la cultura.The question of the international circulation of ideas has become one of the main problems of the intellectual history's renewal in the last years. The matter has been tackled from different theoretical perspectives that had enriched the field's methodological tools. However, the problem of "reception" has been a persistent question in Latin American cultures. Because of its "peripheral" condition, they have faced the experience of translating different meanings since their own emergence. Therefore, it is relevant to enrich those methodological discussions with the suggestions about the topic that have developed for some time in Latin American essays. This paper deals with several authors and discussions that condense the many aspects of this problem. The different cases discussed contribute to outline an active conception of reception as a continuous reconfiguration of meanings, within the framework of a not esencialist conception of culture

We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of coherence due to the use of realistic clocks to measure time to solve the measurement problem. The resulting formulation is framed entirely in terms of quantum objects without having to invoke the existence of measurable classical quantities like the time in ordinary quantum mechanics. The formulation eliminates any privileged role to the measurement process giving an objective definition of when an event occurs in a system.
