Probability without certainty Foundationalism and the Lewis-Reichenbach debate
No full textLike many discussions on the pros and cons of epistemic foundationalism, the debate between C.I. Lewis and H. Reichenbach dealt with three concerns: the existence of basic beliefs, their nature, and the way in which beliefs are related. In this paper we concentrate on the third matter, especially on Lewis’s assertion that a probability relation must depend on something that is certain, and Reichenbach’s claim that certainty is never needed. We note that Lewis’s assertion is prima facie ambiguous, but argue that this ambiguity is only apparent if probability theory is viewed within a modal logic. Although there are empirical situations where Reichenbach is right, and others where Lewis’s reasoning seems to be more appropriate, it will become clear that Reichenbach’s stance is the generic one. This follows simply from the fact that, if P(E|G) > 0 and P(E|not-G) > 0, then P(E) > 0. We conclude that this constitutes a threat to epistemic foundationalism
Genidentity and Topology of Time: Kurt Lewin and Hans Reichenbach
No full textIn the early 1920s, Hans Reichenbach and Kurt Lewin presented two topological accounts of time that appear to be interrelated in more than one respect. Despite their different approaches, their underlying idea is that time
order is derived from specific structural properties of the world. In both works, moreover, the notion of genidentity--i.e., identity through or over time--plays a crucial role. Although it is well known that Reichenbach borrowed this notion from Kurt Lewin, not much has been written about their relationship, nor about the way Lewin implemented this notion in his own work in order to ground his topology. This paper examines these two early versions of the topology of time, and follows the extent of Lewin’s influence on Reichenbach’s proposal
Hans Reichenbach: philosopher-engineer
No full textThis thesis relates Hans Reichenbach's philosophy of science both to his historical context and to his interest in the physical world. The thesis begins with a review of his life, and notes the most significant influences on him. His early ambition to become an engineer stimulated in him an active interest in understanding physical things, and his enjoyment in disseminating what he knew entailed that he maintained a keen interest in contemporary ideas. By the age of twenty he had turned to philosophy to enhance his appreciation of science, and was influenced by Kant and the neo-Kantian interpretation through Ernst Cassirer. His subsequent work is concerned with providing philosophical explication of the major innovations of twentieth century science, and particularly of the implications of Einstein’s Theories of Relativity and of Quantum Mechanics. The thesis proceeds by summarising Kant's and Cassirer's writings on the philosophy of science before examining Einstein's theories. Subsequent chapters analyse Reichenbach's most significant publications in chronological order, namely The Theory of Relativity and A Priori Knowledge (1920), The Philosophy of Space and Time (1928), Experience and Prediction (1938),Philosophic Foundations of Quantum Mechanics (1944), and The Direction of Time (1956). The chapter on Quantum Mechanics is introduced with a summary of the scientific concepts introduced prior to Reichenbach's writing about them. Although he demonstrates the shortcomings of Kant's philosophical justification, the objective Reichenbach set himself throughout his work was to identify the principles that regulate our empirical knowledge. Despite his close friendship with Rudolf Carnap and Moritz Schlick, he differentiated his Empiricism from Logical Positivism, and he refused to accept that Conventionalism could offer a satisfactory analysis of knowledge of the objective world. The final chapter summarises the impact of his writing and his major contribution to philosophy
The Geometry of Conventionality
No full textHans Reichenbach famously argued that the geometry of spacetime is conventional in relativity theory, in the sense that one can freely choose the spacetime metric so long as one is willing to postulate a "universal force field". Here we make precise a sense in which the field Reichenbach defines fails to be a "force". We then argue that there is an interesting and perhaps tenable sense in which geometry is conventional in classical spacetimes. We conclude with a no-go result showing that the variety of conventionalism available in classical spacetimes does not extend to relativistic spacetimes
Talking at Cross-Purposes. How Einstein and Logical Empiricists never Agreed on what they were Discussing about
No full textBy inserting the dialogue between Einstein, Schlick and Reichenbach in a wider network of debates about the epistemology of geometry, the paper shows, that not only Einstein and Logical Empiricists came to disagree about the role, principled or provisional, played by rods and clocks in General Relativity, but they actually, in their life-long interchange, never clearly identified the problem they were discussing. Einstein’s reflections on geometry can be understood only in the context of his “measuring rod objection” against Weyl. Logical Empiricists, though carefully analyzing the Einstein-Weyl debate, tried on the contrary to interpret Einstein’s epistemology of geometry as a continuation of the Helmholtz-Poincaré debate by other means. The origin of the misunderstanding, it is argued, should be found in the failed appreciation of the difference between a “Helmhotzian” and a “Riemannian” tradition. The epistemological problems raised by General Relativity are extraneous to the first tradition and can only be understood in the context of the latter, whose philosophical significance, however, still needs to be fully explored

Reichenbach’s Transcendental Probability
No full textThe aim of this article is twofold. First, we shall review and analyse the Neo-Kantian justification for the
application of probabilistic concepts in physics that was defended by Hans Reichenbach early in his career,
notably in his dissertation of 1916. At first sight this Kantian approach seems to contrast sharply with
Reichenbach’s later logical positivist, frequentist viewpoint. But, and this is our second goal, we shall
attempt to show that there is an underlying continuity in Reichenbach’s thought: typical features of his
early Kantian conceptions can still be recognized in his later work
Reichenbach Fuzzy Set of Transitivity
No full textFuzzy implicators are the basic ingredients of many applications. So it becomes essential to study the various features of an implicator before implementing it in any practical application. This paper discusses the properties of transitivity of a fuzzy relation on a given universe and measure of fuzzy transitivity defined in terms of the Reichenbach fuzzy implicator which is an s-implicator

Uma leitura feminista sobre o desejo feminino em Lilian M (1975), de Reichenbach
No full textIntertwining feminist thought and cinema, this paper search the freshness of women’s desire in CarlosReichenbach’s film Lilian M (1975), and try to recognize how the filmmaker interacts with the 1970sdebates on sexuality and integrates them into the composition of narrative. The film analysis emphasizesthe process of interchange between desire, female displeasure and the masquerade, as an auteur criticalwork, which does not disregard female agency, the domination-exploitation of women, nor the dialogueswith voyeurism and the sexual adventures of erotic comedy.Articulando pensamento feminista e cinema, este artigo indaga o resplandecer do desejo da mulher no filme Lilian M (1975), de Carlos Reichenbach, observando como o cineasta interage com os debates dos anos 1970 sobre a sexualidade feminina e integra-os à composição narrativa. A análise fílmica enfatiza um processo de intercâmbio entre desejo, insatisfação feminina e o mascaramento, como um trabalho autoral crítico, que não desconsidera os diálogos com o voyeurismo, o sistema de dominação-exploração da mulher e as aventuras sexuais da comédia erótica.Articulando pensamento feminista e cinema, este artigo indaga o resplandecer do desejo da mulher no filme Lilian M (1975), de Carlos Reichenbach, observando como o cineasta interage com os debates dos anos 1970 sobre a sexualidade feminina e integra-os à composição narrativa.
