Einstein’s 1935 derivation of mass—energy equivalence is philosophically impor­ tant because it contains both a criticism of purported demonstrations that proceed by analogy and strong motivations for the definitions of the ‘new’ dynamical quantities (viz relativistic momentum, relativistic kinetic energy and relativistic energy). In this paper, I argue that Einstein’s criticism and insights ar...

We introduce a concept of 2 3 PROP generalizing the Kontsevich concept of 1 2 PROP. We prove that some Stasheff-type compactification of the Kontsevich spaces K(m,n) defines a topological 2 3 PROP structure. The corresponding chain complex is a minimal model for its cohomology (both are considered as 2 3 PROPs). We construct a 2 3 PROP End(V ) for a vector space V . Finally, we construct a dg L...

This paper suggests how interpretivist, socio-critical and positivist approaches in information systems research might be integrated. Heinz Klein's approach to information systems was a significant advance on earlier ones, bringing together a number of issues discussed in interpretivist and socio-critical circles, with philosophical groundings. He believed IS research would benefit from integra...

The main goal of OPC is to offer philosophically subtle and historically sound accounts of central concepts in the history of philosophy. Each volume will be a history of its concept in that it will offer a story about the most significant events in the life of the concept from its original inception through its transformations to its modern use. The point of this narrative is to deepen underst...

Recently, many pro-animal thinkers have expressed critical views on the animal rights movement. In particular, the movement has been criticized for being philosophically uninformed, politically regressive, and practically unpersuasive. This paper investigates these criticisms and seeks to map out the philosophy behind the grassroots animal rights movement, specifically. It concludes that the cr...

The problem of converting possibility measures into probability measures has received attention in the past, but not by so many scholars. This question is philosophically interesting as part of the debate between probability and fuzzy sets. The imbedding of fuzzy sets into random set theory as done by Goodman and Nguyen (1985), Wang Peizhuang (1983), among others, has solved this question in pr...

Based on the increased interest in ANT in Media Studies, this paper discusses similarities and differences in the epistemological premises of ANT and German Media Studies and, in particular, Media Aesthetics. Proceeding from well received ANT investigations on the transformational processes of scientific research and the discussion of their importance and suitability for media aesthetic approac...

Martine Nida-Rümelin (1996) argues that color science indicates that behaviorally undetectable spectrum inversion is possible and raises this possibility as an objection to functionalist accounts of visual states of color. I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physi...

The paper shows epistemological, methodological and ontological peculiarities of chemistry taken as a classificatory science of materials using experimental methods. Without succumbing to standard interpretations of physical science, chemical methods of experimental investigation, classification, reference, theorizing, prediction and production of new entities are developed one by one as first ...

Upon initial examination, efforts toward achieving these 2 goals appear philosophically complementary. For example, both tout as a primary benefit improvement of access to health care services. However, closer inspection of these initiatives' more prominent features reveals seemingly irreconcilable demands. As described below, the push toward consumer-driven health plans as a way to offer affor...
