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

Carlão Reichenbach
No full textEste artigo apresenta o cineasta Carlos Reichenbach pelo ponto de vista de seu ex-aluno, assistente e co-roteirista, numa análise inevitavelmente pessoal da obra e do artista, autor de filmes como O império do desejo, Filme demência, Alma corsária e Falsa loura. Reichenbach se adaptou como poucos aos ciclos e guinadas da produção cinematográfica brasileira. De 1968 a 2007 dirigiu 19 filmes de longa metragem, incluindo a participação em quatro longas de episódios. Foi roteirista, produtor, músico, ator, professor, crítico, programador e diretor de fotografia. Sua real importância para o cinema mundial ainda está por ser descoberta.This article presents the filmmaker Carlos Reichenbach from the point of view of his ex-student, assistant in four feature films and co-writer, in an unavoidably personal analysis of the films and the artist, author of O império do desejo (The Empire of Desire), Filme demência, Alma corsária (Buccaneer Soul) and Falsa loura (Fake Blonde), among others. Reichenbach knew as few others how to adapt to the cycles and turn-overs of the Brazilian cinematographic production. From 1968 to 2007 he directed 19 feature films, including episodes in four anthology films. He was a screenwriter, producer, musician, actor, critic, programmer and director of photography. His real importance to world cinema is yet to be discovered
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
