The cosmological constant problem arises at the intersection between general relativity and quantum field theory, and is regarded as a fundamental problem in modern physics. In this paper we describe the historical and conceptual origin of the cosmological constant problem which is intimately connected to the vacuum concept in quantum field theory. We critically discuss how the problem rests on the notion of physically real vacuum energy, and which relations between general relativity and quantum field theory are assumed in order (...) to make the problem well-defined.

In this manuscript we initiate a systematic examination of the physical basis for the time concept in cosmology. We discuss and defend the idea that the physical basis of the time concept is necessarily related to physical processes which could conceivably take place among the material constituents available in the universe. As a consequence we motivate the idea that one cannot, in a well-defined manner, speak about time ‘before’ such physical processes were possible, and in particular, the idea that one (...) cannot speak about a time scale ‘before’ scale-setting physical processes were possible. It is common practice to link the concept of cosmic time with a space-time metric set up to describe the universe at large scales, and then define a cosmic time t as what is measured by a comoving standard clock. We want to examine, however, the physical basis for setting up a comoving reference frame and, in particular, what could be meant by a standard clock. For this purpose we introduce the concept of a `core' of a clock and we ask if such a core can - in principle - be found in the available physics contemplated in the various `stages' of the early universe. We find that a first problem arises above the quark-gluon phase transition where there might be no bound systems left, and the concept of a physical length scale to a certain extent disappears. A more serious problem appears above the electroweak phase transition believed to occur at $\sim 10^{-11}$ seconds. At this point the property of mass disappears and it becomes difficult to identify a physical basis for concepts like length scale, energy scale and temperature - which are all intimately linked to the concept of time in modern cosmology. This situation suggests that the concept of a time scale in `very early' universe cosmology lacks a physical basis or, at least, that the time scale will have to be based on speculative new physics.

We examine the necessary physical underpinnings for setting up the cosmological standard model with a global cosmic time parameter. In particular, we discuss the role of Weyl's principle which asserts that cosmic matter moves according to certain regularity requirements. After a brief historical introduction to Weyl's principle we argue that although the principle is often not explicitly mentioned in modern standard texts on cosmology, it is implicitly assumed and is, in fact, necessary for a physically well-defined notion of cosmic time. (...) We finally point out that Weyl's principle might be in conflict with the wide-spread idea that the universe at some very early stage can be described exclusively in terms of quantum theory.

The Casimir force between two neutral metallic plates is often considered conclusive evidence for the reality of electromagnetic zero-point fluctuations in ‘empty space’. However, it is not well known that the Casimir force can be derived from many different points of view. The purpose of this note is to supply a conceptually oriented introduction to a representative set of these different interpretations. The different accounts suggest that the Casimir effect reveals nothing conclusive about the nature of the vacuum.

Summary The critique of C. H. Ratschow and Knud E. Løgstrup against the existential theology of Bultmann serves as starting point for asking the question about the possibility of thinking metaphysically within theology. Various forms of critique of metaphysics are mentioned, in particular the one of Jürgen Habermas, who’s characterisation of Martin Luther’s theology as „fideistic“ is rejected. After a short presentation of the concept of time in Luther’s De servo aritrio the creation philosophy of Løgstrup is presented as a (...) plausible theological metaphysics. (shrink)

The Danish philosopher K. E. Løgstrup is best known in the Anglo-American world for his original work in ethics, primarily in _The Ethical Demand _. Løgstrup continued to write extensively on issues in ethics and phenomenology throughout his life, and extracts from some of his later writings are now also available in translation in _Beyond the Ethical Demand_. In _Concern for the Other: The Ethics of K. E. Løgstrup_, eleven scholars examine the structure, intention, and originality of Løgstrup's ethics as (...) a whole. This collection of essays is a companion to _Beyond the Ethical Demand_, as well as to _The Ethical Demand_. The essays examine Løgstrup’s crucial concept of the “sovereign expressions of life”; his view of moral principles as a substitute for, or inferior form of, ethics; his relationships to other philosophers, including the twentieth-century British moral philosophers; and the role of his Lutheran background in his ethics. Løgstrup also firmly advanced the controversial thesis, examined by several essays in this volume, that the demand for “other-concern” central to his ethics does not depend on religious faith. “The significance of Løgstrup’s work is well demonstrated by the substantive criticisms made of that work by the essays here collected. Hopefully this book will encourage others to engage this significant but unfortunately not well-known thinker.” —_Stanley Hauerwas, Gilbert T. Rowe Professor of Theological Ethics, Duke Divinity School_ “Svend Andersen and Kees van Kooten Niekerk have done a great service for everyone with the publication of this stellar book on the thought of Knud E. Løgstrup, the most prominent Danish theologian-philosopher of the last century. CONCERN FOR THE OTHER includes essays by renowned thinkers who critically engage Løgstrup’s work with both insight and depth. The book thereby provides an engagement with this important thinker’s ideas about morality, trust, and responsibility and yet also presents features of the current state of the debate within ethics. I enthusiastically commend this book to anyone interested in contemporary ethics and moral theory as well as the relation between theology and philosophy.” —_William Schweiker, Edward L. Ryerson Distinguished Service Professor of Theological Ethics, The University of Chicago_. (shrink)

The article presents an interpretation of certain aspects of John Dewey’s psychological works. The interpretation aims to show that Dewey’s framework speaks directly to certain problems that the discipline of psychology faces today. In particular the reflexive problem, the fact that psychology as an array of discursive practices has served to constitute forms of human subjectivity in Western cultures. Psychology has served to produce or transform its subject-matter. It is shown first that Dewey was aware of the reflexive problem, and (...) found that it needed to be addressed. Next, three concepts of Dewey’s psychology are drawn in: subjectivity, habit and morality. Dewey is interpreted as articulating what we today would call a practice-orientated approach to psychology, in which moral and practical reasoning is seen as a dimension of all knowledge and action. Subjectivity is understood as a function emerging with complex interaction. Finally, a Deweyan approach to how psychology and other social sciences can cope with, and make positive use of, the reflexive problem, is outlined. By acknowledging their existence in the world they study, i.e. by becoming moral sciences that realize their moral and political implications, the social sciences can become problem-solving instruments that serve to help create a democratic public, a community as an actual social idea. It is pointed out that Dewey had an attractive view both of psychology – the subject-matter and of Psychology – the discipline and its practices – and ventured on the rare attempt at explicating how they are connected in what he called Great Societies, what we today would call post- or late-modernity, and how Psychology can help to constitute Great Communities in which human beings might flourish.

The article deals with the relationship between theological ethics and moral philosophy. The former is seen as a theoretical reflection on Christian ethics, the latter as one on secular ethics. The main questions asked are: Is there one and only one pre-theoretical knowledge about acting rightly? Does philosophy provide us with the theoretical framework for understanding both Christian and secular ethics? Both questions are answered in the negative. In the course of argument, four positions are presented: theological unificationism, philosophical unificationism, (...) theological separationism and Lutheran dualism. It is argued that the latter position is most convincing. It is dual in the sense of being both a theory of Christian ethics and of including a recognition of natural law. Hence, it unites a particularistic and a universalistic point of view. In the last section a reformulation of the Lutheran position is attempted in making use of the ethical theory of Knud E. Løgstrup''s The Ethical Demand. (shrink)

L’autore si propone di investigare i rapporti tra retorica e tempo nel “Dialogo sui due massimi sistemi del mondo” di Galileo Galilei, giustificando l’analisi retorico-stilistica della prosa scientifica sintesi di ragione e immaginazione, stabilendo un parallelo tra l’abbattimento della discontinuità tra Cielo e Terra e alcune innovazioni retoriche della prosa galileiana che precede il Dialogo e prendendo in considerazione passi del “Dialogo” in cui Galileo manipola i concetti di ‘tempus’ e ‘aeternitas’ tramite metafore, similitudini e altre figure, che sono strumento (...) essenziale alla dimostrazione della tesi che interessa, cioè quella della fondamentale identità tra cielo e terra, dell’unità del tempo cosmico.

Many people alive today grew up during the so-called Cold War and even more experienced the fall of the Berlin Wall. The Cold War can be taken as the name of the order of international relations during four decades of the twentieth century. In the following, I want first to comment on the concept of world order and the related one of institution (law). Then I shall deal with the relation between these concepts and various schools in international politics. Next, (...) I will pay attention to the ethical dimensions of those schools. And finally, I want to reflect on the place of theology in the ethics of international relations. My thesis is (1) that theological ethics has an important role to play in understanding contemporary international politics (IP); (2) that if theological ethics takes a Lutheran starting point, it will endorse elements both in the liberal and the realist tradition of international relations theory. As I regard Kant and Kissinger as representatives of the two schools, I hope that explains my somewhat provocative title. (shrink)

Western philosophy has been greatly influenced by visual metaphors. Knowing something has commonly, yet implicitly, been conceptualized as seeing something clearly, learning has been framed as being visually exposed to something, and the mind has been understood as a ‘mirror of nature’. A whole ‘epistemology of the eye’ has been at work, which has had significant practical implications, not least in educational contexts. One way to characterize John Dewey’s pragmatism is to see it as an attempt to replace the epistemology (...) of the eye with an epistemology of the hand. This article develops the epistemology of the hand on three levels: A level of embodiment and metaphors, of craftsmanship and social practices, and of schooling and education. (shrink)

Max Weber und Erich Wittenberg. Eine Erwiderung auf des letzteren Artikel.

Psychologists have traditionally been reluctant to investigate not just the historical nature of their subject matter — humans as acting, thinking and feeling beings — but even more so the historical nature of their discipline, its theories and practices. In this article, I will try to take seriously the historical transformation in the West from industrial society to consumer society. After having introduced these socio-economic designations, I shall try to illustrate how the transformation relates to changes in significant societal practices (...) with a particular attention to education and work. Since its inception, psychology has been deeply involved in the management of human beings in and through these practices, and considerable changes have taken place in the dominant psychologies with the change from industrial to consumer society. I interpret psychoanalysis and behaviourism as psychologies of industrial society, and humanistic psychology and the more recent wave of social constructionism as psychologies of consumer society. With shifting psychologies also come shifting life problems and pathologies, which I briefly address. (shrink)

Naturen erkendt af Kant og Løstrup – Hvor stor er forskellen?

This collection of papers is from the Ninth European Conference on the Philosophy of Religion held at the University of Aarhus, Denmark in August 1992. The theme of the conference was theism and its modern alternatives. Why alternatives? There is no agreement on the answer to that question. Before outlining the nature of the disagreements, there is a need to distinguish theism, where it means some belief in God, and theism as a certain kind of philosophical response to that belief. (...) If theism is to be spoken of in both contexts, the following question arises -- is philosophical theism an adequate response to religious theism? (shrink)

The relationship between religion and politics has received increased attention in recent time. For religious traditions, this increased attention has been cause to reflect on their position regarding political life. Is it permissible for a religious person to engage in political life at all? Should he or she attempt to impose his religious views on the entire society? This book deals with Luther’s reflections on the relation between his religious views and politics. Luther understands political authority as a reflecting a (...) God-given natural order. Christians are called to practice neighborly love also in political life. In Luther’s view, politics consists in the conversion of love into power. Can this idea still be defended today? (shrink)

The paper places the trendy notion of virtuality and virtual reality in a conceptual and historical context that makes it useful in a semiotic perspective. Virtuality is connected with the classical notion of fictionality, in its meaning of both invention and deception. Historically an active, a passive, and a neutral version of the concept can be distinguished. The notion is reinterpreted as a variant of the semiotic processes of deixis. In relation to nature - scenarios, prognoses, hypotheses, etc. - virtuality (...) is seen as a means of anchoring the human subject in nature instead of constructing a nonreal universe separated from it.
