Erwin Schroedinger has been described as one of the greatest figures of theoretical physics, but there is another side to the man: not only did his work revolutionize physics, it also radically changed the foundations of our modern world-view, modern biology, philosophy of science, philosophy of the mind, and epistemology.

Manfred Eigen extended Erwin Schroedinger’s concept of “life is physics and chemistry” through the introduction of information theory and cybernetic systems theory into “life is physics and chemistry and information.” Based on this assumption, Eigen developed the concepts of quasispecies and hypercycles, which have been dominant in molecular biology and virology ever since. He insisted that the genetic code is not just used metaphorically: it represents a real natural language.However, the basics of scientific knowledge changed dramatically within the second (...) half of the 20th century.Unfortunately, Eigen ignored the results of the philosophy of science discourse on essential features of natural languages and codes: a natural language or code emerges from populations of living agents that communicate. This contribution will look at some of the highlights of this historical development and the results relevant for biological theories about life. (shrink)

Authored by an acclaimed teacher of quantum physics and philosophy, this textbook pays special attention to the aspects that many courses sweep under the carpet. Traditional courses in quantum mechanics teach students how to use the quantum formalism to make calculations. But even the best students - indeed, especially the best students - emerge rather confused about what, exactly, the theory says is going on, physically, in microscopic systems. This supplementary textbook is designed to help such students understand that they (...) are not alone in their confusions (luminaries such as Albert Einstein, Erwin Schroedinger, and John Stewart Bell having shared them), to sharpen their understanding of the most important difficulties associated with interpreting quantum theory in a realistic manner, and to introduce them to the most promising attempts to formulate the theory in a way that is physically clear and coherent. The text is accessible to students with at least one semester of prior exposure to quantum (or "modern") physics and includes over a hundred engaging end-of-chapter "Projects" that make the book suitable for either a traditional classroom or for self-study.

What is quantum mechanics about? The most natural way to interpret quantum mechanics realistically as a theory about the world might seem to be what is called wave function ontology: the view according to which the wave function mathematically represents in a complete way fundamentally all there is in the world. Erwin Schroedinger was one of the first proponents of such a view, but he dismissed it after he realized it led to macroscopic superpositions (if the wave function evolves (...) in time according to the equations that has his name). The Many-Worlds interpretation1 accepts the existence of such macroscopic superpositions but takes it that they can never be observed. Superposed objects and superposed observers split together in different worlds of the type of the one we appear to live in. For these who, like Schroedinger, think that macroscopic superpositions are a problem, the common wisdom is that there are two alternative views: "Either the wave function, as given by the Schroedinger equation, is not everything, or is not right" [Bell 1987]. The deBroglie-Bohm theory, now commonly known as Bohmian Mechanics, takes the first option: the description provided by a Schroedinger-evolving wave function is supplemented by the information provided by the configuration of the particles. The second possibility consists in assuming that, while the wave function provides the complete description of the system, its temporal evolution is not given by the Schroedinger equation. Rather, the usual Schroedinger evolution is interrupted by random and sudden "collapses". The most promising theory of this kind is the GRW theory, named after the scientists that developed it: Gian Carlo Ghirardi, Alberto Rimini and Tullio Weber.. It seems tempting to think that in GRW we can take the wave function ontologically seriously and avoid the problem of macroscopic superpositions just allowing for quantum jumps. In this paper we will argue that such "bare" wave function ontology is not possible, neither for GRW nor for any other quantum theory: quantum mechanics cannot be about the wave function simpliciter. That is, we need more structure than the one provided by the wave function. As a response, quantum theories about the wave function can be supplemented with structure, without taking it as an additional ontology. We argue in reply that such "dressed-up" versions of wave function ontology are not sensible, since they compromise the acceptability of the theory as a satisfactory fundamental physical theory. Therefore we maintain that: 1- Strictly speaking, it is not possible to interpret quantum theories as theories about the wave function; 2- Even if the wave function is supplemented by additional non-ontological structures, there are reasons not to take the resulting theory seriously. Moreover, we will argue that any of the traditional responses to the measurement problem of quantum mechanics (Bohmian mechanics, GRW and Many-Worlds), contrarily to what commonly believed, share a common structure. That is, we maintain that: 3- All quantum theories should be regarded as theories in which physical objects are constituted by a primitive ontology. The primitive ontology is mathematically represented in the theory by a mathematical entity in three-dimensional space, or space-time. (shrink)

From the German physicist Erwin Schrödinger's text, What is life , the possible limits of conceptual division between physics and biology are analyzed. Is there a limit between physics and biology? Or can biology be reduced to physics? Different views will be analyzed among scientists and philosophers.A partir do texto do físico alemão E.Schroedinger, O que é vida? , analisam-se os possíveis limites de demarcação conceitual entre física e biologia.

A Nobel prize winner, a great man and a great scientist, Erwin Schrödinger has made his mark in physics, but his eye scans a far wider horizon: here are two stimulating and discursive essays which summarize his philosophical views on the nature of the world. Schrödinger's world view, derived from the Indian writings of the Vedanta, is that there is only a single consciousness of which we are all different aspects. He admits that this view is mystical (...) and metaphysical and incapable of logical deduction. But he also insists that this is true of the belief in an external world capable of influencing the mind and of being influenced by it. Schrödinger's world view leads naturally to a philosophy of reverence for life. (shrink)

Combinatory logic started as a programme in the foundation of mathematics and in an historical context at a time when such endeavours attracted the most gifted among the mathematicians. This small volume arose under quite differ ent circumstances, namely within the context of reworking the mathematical foundations of computer science. I have been very lucky in finding gifted students who agreed to work with me and chose, for their Ph. D. theses, subjects that arose from my own attempts 1 to (...) create a coherent mathematical view of these foundations. The result of this collaborative work is presented here in the hope that it does justice to the individual contributor and that the reader has a chance of judging the work as a whole. E. Engeler ETH Zurich, April 1994 lCollected in Chapter III, An Algebraization of Algorithmics, in Algorithmic Properties of Structures, Selected Papers of Erwin Engeler, World Scientific PubJ. Co. , Singapore, 1993, pp. 183-257. I Historical and Philosophical Background Erwin Engeler In the fall of 1928 a young American turned up at the Mathematical Institute of Gottingen, a mecca of mathematicians at the time; he was a young man with a dream and his name was H. B. Curry. He felt that he had the tools in hand with which to solve the problem of foundations of mathematics mice and for all. His was an approach that came to be called "formalist" and embodied that later became known as Combinatory Logic. (shrink)

It is customary to draw a distinction between statements unconfirmable in practice and statements unconfirmable in principle. It may be impossible, for example, to confirm the statement “The star most distant from us in the universe has recently doubled in size,” but this impossibility is not of a logical kind. We could conceive of tests which would either confirm or disconfirm the statement, even if in fact we cannot carry them out. In contrast, the statement ‘Everything has recently doubled in (...) size’ cannot be confirmed for logical reasons, or so some philosophers have claimed. If everything were to double in size, including the very measuring rods used to detect expansions, it would be logically impossible, so the argument runs, to either confirm or disconfirm the above statement.

Discussions about the content of Plato’s Gorgias mostly follow the structure of this dialogue given by the change of the interlocutors. As plain as this change is, as little does it correspond with the development of the subject. This becomes obvious if we compare the division of the dialogue by the interlocutors with the division of the leading questions. New themes do not start with a new person, but only in the course of the conversation with Gorgias, Polos, and Callicles (...) respectively Socrates gets a more fundamental niveau for an old question or introduces a new subject.

The European Union is working towards harmonizing legislation across Europe, in order to improve cross-border interchange of legal information. This goal is supported for instance via standards such as the European Law Identifier and the European Case Law Identifier, which provide technical specifications for Web identifiers and suggestions for vocabularies to be used to describe metadata pertaining to legal documents in a machine readable format. Notably, these ECLI and ELI metadata standards adhere to the RDF data format which forms the (...) basis of Linked Data, and therefore have the potential to form a basis for a pan-European legal Knowledge Graph. Unfortunately, to date said specifications have only been partially adopted by EU member states. In this paper we describe a methodology to transform the existing legal information system used in Austria to such a legal knowledge graph covering different steps from modeling national specific aspects, to population, and finally the integration of legal data from other countries through linked data. We demonstrate the usefulness of this approach by exemplifying practical use cases from legal information search, which are not possible in an automated fashion so far. (shrink)

The aim of this article is to free Aristotle's Metaphysics, especially book XII (Lambda), frome some metaphysical and theological presuppositions by detecting their inappropriate conceptual framwork, which once was progressive, but now holds an obsolete position. Ousia, being (not substance, a much later concept, construed to solve other problems than Aristotle's), stand for a question, not for an answer. Book Lambda develops a highly speculative argument for this queston. The famous noesis noeseos says that empirical being and knowledge is the (...) realization of a noetic structure (noesis), laid down in our most fundamental opinioons about being. (shrink)

Clinical ethics consultation service remains undeveloped in developing countries. It is recognised that its introduction poses challenges. Malaysia, a multicultural society with diverse religions, values and perceptions further complicate the introduction of formal clinical ethics consultation service. Clinicians attending a national congress workshop completed a Strengths–Weaknesses–Opportunities–Threats analysis. The aim was to gain insight into clinician’s expectations and promote initiatives leading to the introduction of clinical ethics consultation service. Clinicians agree that clinical ethics consultation service can improve quality of care, reduce (...) healthcare costs and advocate for patients and providers. The analysis highlighted constraints in sufficient critical mass of relevant expertise and restricted opportunities for training. The opportunities lie in education, curriculum development and availability of dedicated proponents. Cultural barriers, limited resources, lack of awareness, differenc... (shrink)

Schrödinger discusses what an elementary particle is. This essay originally appeared in the journal Endeavour.

Wissen wir, wer oder was unseren Lebensgang bestimmt? Wissen wir überhaupt, was in uns und ausserhalb von uns abläuft? Das einzig Gewisse ist unser Tod, doch was hilft die Gewissheit unseres Todes, wenn ungewiss bleibt, wann er kommt? Unsere Bedürfnisse kennen wir, aber wo sind die Grenzen der Befriedigung? Wenn unsicher geworden ist, wer oder was das bestimmt, was faktisch geschieht, wenn die Welt uns körperlich und seelisch bedrängt und die einzige Gewissheit in der Zukunft unser Tod ist, wenn uns (...) unsere Bedürfnisse und die Grenzen ihrer Befriedigung unklar geworden sind, dann hilft nichts mehr als das Nachdenken – das Nachdenken über unsere Natur und ihren Platz in der Welt, über die Hierarchie unserer Bedürfnisse, darüber, wie wir das Gelingen unseres Lebens mit Vernunft und Gerechtigkeit in Einklang bringen. Kurz, es hilft nichts als der Epikureismus. ********** Do we know who or what determines the course of our lives? Do we even know what is going on inside and outside of us? The only certain thing is our death, but what good is the certainty of our death if it remains uncertain when it will come? We know our needs, but where are the limits to their fulfilment? When it has become uncertain who or what determines what actually happens, when the world oppresses us physically and emotionally and the only certainty in the future is our death, when our needs and the limits of their fulfilment have become unclear to us, then nothing helps more than reflection - reflection on our nature and its place in the world, thinking about the hierarchy of our needs, about how we can harmonise the success of our lives with reason and justice. In short, nothing helps but Epicureanism. (shrink)

With the conviction that "the gap between traditional morality and the avant-garde approach is widening," Erwin W. Lutzer offers this precise, easy-to-understand, and knowledgeable critique of situation ethics. This presentation adds new insights to the discussion of morality and the ethic of love. Lutzer pinpoints the fallacies of the situationist's philosophy and offers a biblical alternative that clearly recognizes and deals with moral conflicts.

In this work, first published in two volumes in 1890 and 1894, Erwin Rohde, the German classical scholar and friend of Nietzsche, describes the ancient Greek cult of souls and establishes the sources of the belief in the immortality of the soul, exploring its relation to life both before and after death. This belief in the survival of the soul already existed in the earliest Greek writings, but when and from where did it originate? In Volume 1 Rohde examines (...) belief in the soul as it appears in Homeric poetry and within local cults, and finds that the idea of an afterlife is already represented in different forms in the works of Hesiod and Aeschylus. He also discusses burial rites and the Eleusinian Mysteries. Psyche, reissued here in the 1898 edition, remains a standard reference work on this topic. (shrink)
