From Einstein's point of view, his General Relativity Theory had strengths as well as failings. For him, its shortcoming mainly was that it did not unify gravitation and electromagnetism and did not provide solutions to field equations which can be interpreted as particle models with discrete mass and charge spectra, As a consequence, General Relativity did not solve the quantum problem, either. Einstein tried to get rid of the shortcomings without losing the achievements of General Relativity Theory. Stimulated by papers (...) of Weyl 465) and Eddington 194), from 1923 onward, he believed that, to reach this goal, one has to transit to space–times which possess more comprehensive geometrical structures than the Riemann space–time. This was the beginning of a decade's lasting search for a unitary field theory. We describe this exciting part of the history of physics, discuss achievements and failures of this development, and ask how these early attempts of a unified theory strike us today. Taking into account the fact that the Equivalence Principle only speaks for a geometrization of gravitation, we consider an alternative way to give those non-Riemannian structures which were introduced by the unitary field approach a physical meaning, namely the meaning of a generalized gravitational field. This is interesting since there are arguments in favor of such a generalization of General Relativity Theory, e.g., the problems the latter theory meets with if one tries to quantize it and to unify gravitation with other interactions.

Recently the English scholar Heather McKay defended the thesis that before the third century CE the synagogue had never been a place of sabbath worship. In this article the author reviews all the material presented by her, adds some new evidence, and comes to the conclusion that the evidence points to a situation in which already before 70 CE the synagogue served as a place of sabbath worship.

From both physical and epistemological viewpoints, the following theses, which nowadays are often discussed in the literature, are examined: Nonlinear thermodynamics renders it possible to grasp evolutionary physical processes; for thermodynamics it introduces, instead of idealized reversible time, a directed time into physics; thus a science is established that is nearer to reality than classical physics. To analyze these theses, the relation of thermodynamics to dynamical physics is considered. In particular, it is demonstrated that, in classical as well as in (...) modern thermodynamics, irreversibility is introduced via conditions which must be formulated in addition to the dynamical laws. To show the reason for this, the epistemological status of the physical time conception is analyzed, and its character as a physical measurement quantity is established. (shrink)

The ArgumentThe idea of evolution doubtlessly marks a revolution in our way of thinking. It is the most recent achievement of philosophy and forms the basis of the modern world picture. Current discussions concerning the status of science now convey the impression that any scientific discipline that wants to satisfy modern requirements must also become a theory of evolution. These discussions ignore the reasons which once induced Kant to desist from reformulating classical mechanics as a theory of evolution and instead (...) to found his critical philosophy, according to which the epistemological starting points of natural science and philosophy are different in principle. In other words, there is no examination of whether the reasons given by Kant are of a principle nature so that they are still valid today, but rather, ignoring Kant's arguments, it is taken for granted that a different physical theory than classical mechanics could achieve this.Because nonlinear thermodynamics in particular is often presented as a candidate that justifies hopes of an evolutionary physics, the position of this branch within the structure of physics will be investigated here. It will be seen that a historical component is introduced into physics via initial, boundary, and other supplementary conditions, but that this does not mean that historicity has been grasped in laws, which is of course the point of a scientific theory of development.It is demonstrated that the conclusion drawn for physics by some authors from nonlinear thermodynamics, according to which physics today becomes an evolutionary physics incorporating the cognitive subject, is wrong. The progress made by modern thermodynamics is, without doubt, significant. The widespread philosophical interpretation of thermodynamics rests, however, on an antiquated ontologization of physical concepts and thus on the usual procedure of mechanicism.If one tries to introduce the conception of evolution into natural science by leveling the difference between philosophy and natural science in a mechanistic manner, then the dialectical evolutionary conception which represents a new epoch of human thinking degenerates to an evolutionism, where lawfulness is replaced by accidentalness.

It is demonstrated that in quantized general relativity one is led to Jordan-Fock type uncertainty relations implying the occurrence of cut-off lengths. We argue that these lengths (i) represent limitations on the measurability of quantum effects of general relativity and (ii) provide a cut-off length of quantum divergences.

The difference between the measurement bases of classical and quantum mechanics is often interpreted as a loss of reality arising in quantum mechanics. In this paper it is shown that this apparent loss occurs only if one believes that refined everyday experience determines the Euclidean space as the real space, instead of considering this space, both in classical and quantum mechanics, as a theoretical construction needed for measurement and representing one part of a dualistic space conception. From this point of (...) view, Einstein's program of a unified field theory can be interpreted as the attempt to find a physical theory that is less dualistic. However, if one rgards this dualism as resulting from the requirements of measurements, one can hope for a weakening of the dualism but not expect to remove it completely. (shrink)

Rediscussing early arguments have led to the founding of quantum electrodynamics, but it is shown that one cannot employ them for the founding of quantum GRT. These arguments rather demonstrate that Einstein's GRT is essentially classical.

It is often assumed that deflationist accounts of truth are a product of philosophy of logic and language in the twentieth century. In this paper I show why this assumption is historically short-sighted. An early version of deflationism about truth can already be found in Brentano’s 1889 lecture “On the Concept of Truth.” That Brentano is a precursor of deflationism has gone largely unnoticed because of a different reception of his lecture: according to most scholars, Brentano proposes in it a (...) revision of the correspondence theory of truth that he later rejected in favour of an epistemic theory. Contrary to this received interpretation, I argue that Brentano actually tried to show how one can minimize an account of truth without thereby sacrificing a robust realist intuition about the objectivity of truth. Brentano held on to this deflationist view in his later years, when he assigned self-evident judgments a primary role in our understanding of truth. (shrink)

The integration of ethics into the day-to-day work of research and innovation is an important but difficult challenge. However, with the Aachen method for identification, classification and risk analysis of innovation-based problems an approach from an engineering perspective is presented that enables the integration of ethical, legal and social implications into the day-to-day work of R&I practitioners. AMICAI appears in particular capable of providing a procedural guidance for R&I practitioners based on a method established in engineering science, breaking down the (...) object of consideration into partial aspects and prioritizing the innovation-based problems in dependence of potential risk. This enables the user to apply AMICAI continuously during all stages of the research and development process and to analyze and choose between certain sociotechnical alternatives. In this way, problems that affect ethical, legal, and social aspects can be understood, reflected and considered in the mostly technically focused R&D process. The paper gives a general guidance about AMICAI by describing principles and assumptions, providing the steps of analysis and application aids, giving an example application, explaining the necessary adjustments of AMICAI compared to the methodical basis of failure mode, effects, and criticality analysis and discussing the advantages and limits. AMICAI’s simple applications can stimulate interdisciplinary cooperation in the R&D process and be a starting point for the development of an “open RRI risk analysis platform” allowing society to evaluate innovation-based problems.

Ever since the publication of 'Truth' in 1959 Sir Michael Dummett has been acknowledged as one of the most profoundly creative and influential of contemporary philosophers. His contributions to the philosophy of thought and language, logic, the philosophy of mathematics, and metaphysics have set the terms of some of most fruitful discussions in philosophy. His work on Frege stands unparalleled, both as landmark in the history of philosophy and as a deep reflection on the defining commitments of the analytic school.This (...) volume of specially composed essays on Dummett's philosophy presents a new perspective on his achievements, and provides a focus for further research fully informed by the Dummett's most recent publications. Collectively the essays in philosophy of mathematics provide the most sustained discussion to date of the role of Dummett's diagnosis of the root of the logico-mathematical paradoxes in his case for an intuitionist revision of classical mathematics. The themes of other essays include a fundamental challenge to Dummett's Fregean understanding of predication, and a criticism of his case for logical revision outside of mathematics. (shrink)

Entrepreneurial agency—the individual power to change environments—is central to entrepreneurship research. Yet, from a social inequality perspective, beliefs in an entrepreneurial agency might differ based on the social class environments individuals are born into. Drawing on social cognitive theories, our findings across three data sets among students from Germany and entrepreneurs from the United States indicate that social class origins are associated with entrepreneurial self-efficacy (ESE) beliefs in adulthood. Exploring the underlying mechanisms, we find that students’ early entrepreneurial experiences in (...) education and practice are indicative of reproducing the class gap in ESE. When individuals collect mastery experiences such as social mobility or entrepreneurial success, their lower social class origins turn out to be associated with enhanced entrepreneurial agency beliefs. We discuss the implications for further research on social class, inequality, and entrepreneurship. (shrink)

Kant offered a subtle theory of consciousness and self-knowledge which articulated the intuition that consciousness is a mode of being in a mental state, as opposed to a property of that state. This paper develops this theory and argues that McDowell's treatment of these issues in "Mind" and "World" overlooks the resources of Kant's views. McDowell conflates consciousness and self-consciousness, leading him to formulate too demanding a constraint on rational concept use. Kant's theory can be developed so as to avoid (...) this unfortunate corollary. The paper concludes by comparing Kant's account to contemporary approaches to the problem of consciousness. (shrink)

Many virtue epistemologists conceive of epistemic competence on the model of skill —such as archery, playing baseball, or chess. In this paper, I argue that this is a mistake: epistemic competences and skills are crucially and relevantly different kinds of capacities. This, I suggest, undermines the popular attempt to understand epistemic normativity as a mere special case of the sort of normativity familiar from skilful action. In fact, as I argue further, epistemic competences resemble virtues rather than skills—a claim that (...) is based on an important, but often overlooked, difference between virtue and skill. The upshot is that virtue epistemology should indeed be based on virtue, not on skill. (shrink)

In this carefully argued critique, Steven Horst pronounces the theory deficient.

How to understand Brentano’s account of truth is a question of some controversy. A number of different views have been put forward as positions that Brentano held at some stage in his career. The received view has it that the early Brentano subscribed to a form of correspondence theory which he later rejected in favor of a definition of truth in terms of correct judging, where the correctness of a judgment is defined in terms of the notion of self-evidence (see (...) Kraus 1966, Szrednicki 1965, Stegmüller 1969, Kamitz 1983, Chrudzimski 2001). This fundamental shift in Brentano’s view is regarded as a change from an ontological to a “gnoseological”, i.e. epistemic, theory of truth (see Kastil 1934). Brentano’s mature view is sometimes said to resemble a neo-Kantian conception of truth or related views (see Kraus 1966, van der Schaar 1999, 2003), it has been compared with a coherence theory of truth (see Krantz 1990/91), and it is regarded as embracing a form of alethic anti-realism that places a substantial epistemic constraint on the concept of truth (see Künne 2003). More recently, Charles Parsons suggested that the early Brentano may also be regarded as a precursor of a deflationist theory of truth (see Parsons 2004). Following up on this proposal, the received view has been challenged by a new interpretation that ascribes to Brentano a deflationist position that he held throughout his career in combination with the view that truth pertains primarily to self-evident judgment (see Brandl forthcoming). Section 1 first summarizes the received view and then indicates two problems raised by this interpretation. Section 2 explains in which sense Brentano may have been a deflationist and how this interpretation avoids the problems of the received view. (shrink)
