Warum haben die deutschen Physiker während des Zweiten Weltkriegs keine Atombombe entwickelt? Seit mehr als 25 Jahren sind sich die Historiker einig, dass die deutschen Physiker wussten, wie eine Atombombe gebaut werden muss, dass aber ein Programm wie das amerikanische Manhattan‐Projekt zu ihrer Realisierung in Deutschland, erst recht während des Krieges, unmöglich war. Eine genaue Analyse aller erhaltenen Original‐Dokumente über die Arbeit an der Atombombe während des,Dritten (...)

Es wird nachgewiesen, dass die deutschen Physiker bis zum Ende des Krieges nicht bemerkt hatten, dass eine Atombombe nur mit schnellen Neutronen realisiert werden kann. Nur Heisenberg hatte das richtige Prinzip spät erkannt, es aber nicht eindeutig kommuniziert und auch in keiner Weise physikalisch vertieft. Die physikalisch korrekte Interpretation der Dokumente zeigt, dass die deutschen Physiker während des Krieges erfolglos versuchten, einen Reaktor zu entwickeln, der auch eine Voraussetzung für den Bau einer Plutonium‐Bombe gewesen wäre. Aber sie wussten nicht, wie eine Bombe realisiert werden kann, weil sie nie an einer realistischen Theorie der Atombombe gearbeitet hatten. Summary: Misinterpreted Documents and Ignored Physical Facts: The History of ‘Hitler's Atomic Bomb’ needs to be corrected. Why have the German physicists not developed an atomic bomb during World War II? For more than 25 years, the historians agree that they knew how to build the bomb, but that a bomb‐development programme of the size of the US‐Manhattan‐Project would not have been possible in wartime Germany. A detailed analysis of all preserved documents on the German atomic bomb research during the ‘Third Reich’, however, reveals considerable mistakes by the authors due to incomplete analysis of documents, misinterpretations of scientific explanations and ignoring of physical facts. It is shown that until the end of the war the German physicists did not know that an atomic bomb can only be made with fast neutrons, except Heisenberg, who, however, discovered it rather late, did not communicate it clearly and did not study any bomb physics. The physically correct interpretation of the documents reveals that the German physicists worked unsuccessfully on a reactor, which would have been a prerequisite for a plutonium bomb. But they did not know how to build a bomb because they never worked on a realistic bomb theory. (shrink)

It is customary to identify three broad classes of grading particles: additive particles like also, exclusive particles like only, and scalar particles like even (cf. König (1991); in the examples, grave accent stands for the main, falling accent).

The critical intention of this article does not focus on a comprehensive socio-cultural evaluation of gambling. Rather, its perspective is guided towards ways of picturing gambling and the subject of the gambler in different theoretical contexts. It is argued that one might expand philosophical conceptions of practical self-determination by taking an interdisciplinary look at gambling. However, such an attempt runs into the danger of painting an overly simplistic picture of self-control as self-continence, which can be found in theoretical approaches pathologizing (...) the gambler. In order to avoid such an outcome, an interdisciplinary analogy combining psychoanalytical and philosophical thought is presented. This analogy brings together the perspectives of the analysand and the gambler. By confronting these scenarios of human agency, it is shown that practical self-determination depends on instances of daring that can be related to certain gambling practices, too. The interdisciplinary view on gambling highlights its potentials for self-exploration, without neglecting the fact that an appropriate realization of such a self-exploration requires experiential and interpersonal conditions that often collide with the harsh reality of gambling practices.

This paper deals with what has been called "ars inveniendi" (’art of finding‘) in antiquity, medieval and early modern times. A survey of different techniques of finding tenable and relevant arguments is presented (among them, the Topical tradition, Status theory, Debate theory, Encyclopedic systems, Creativity techniques). Their advantages and disadvantages are critically compared. It is suggested that a mixture of strategies of finding arguments should be used. Finally, a few remarks showing the relationship beween the strategies of finding arguments and (...) creativity in general are given. (shrink)

The argument from faultless disagreement against moral realism is based on the alleged possibility of cognitively faultless moral disagreement, CFD. This possibility contradicts the pre-theoretic intuition that moral truth is knowable, in principle, the so-called epistemic constraint on moral truth, EC. In this paper, I discuss the realist’s two options to cope with this argument. First of all, I point out the realist’s strategies to explain the possibility of cognitively faultless error, which is implied by CFD. Then I discuss one (...) promising option to respond to the argument from faultless disagreement: accepting both CFD and EC but blocking the ensuing contradiction by invoking an equivocation as regards the notion of knowability. After pointing out the drawbacks of this solution I discuss the other promising option: rejecting CFD by drawing on an agnostic stance on the part of cognitively blameless thinkers as regards moral propositions they cannot agree on. Yet this option faces the problem that EC has to be denied. In concluding the paper, I outline the prospects of an attractive objectivist shape of moral antirealism, which is also affected by the argument from faultless disagreement. (shrink)

COVID-19 has revealed that science needs to learn how to better deal with the irreducible uncertainty that comes with global systemic risks as well as with the social responsibility of science towards the public good. Further developing the epistemological principles of new theories and experimental practices, alternative investigative pathways and communication, and diverse voices can be an important contribution of history and philosophy of science and of science studies to ongoing transformations of the scientific enterprise.

This work attempts to show that the Scottish common sense philosophers Thomas Reid, James Oswald and James Beattie, had a substantial influence upon the development of German thought during the period of the late enlightenment. Their works were thoroughly reviewed in German philosophical journals and translated into German soon after they had appeared in English. Whether it was Mendelssohn, a rationalist, Lossius, a materialist, Feder, a sensationalist, Tetens, a critical empiricist, or Hamann and Jacobi, irrationalist philosophers of faith, important philosophers (...) read the Scots and found them relevant for the solution of their problems. The Scots were seen as not just opposing Hume's skepticism, but also as complementing his more positive tenets. The most important chapter of this work shows that even Kant, who in this regard is known only for his devastating criticism of the Scots, learned much from them. It is argued that the Scottish influence opens a new perspective for the understanding of the German enlightenment, revealing how central were the twin problems of idealism versus realism, on the one hand, and of philosophical justification versus mere descriptive metaphysics, on the other.

Der vorliegende Aufsatz widmet sich der Charakterisierung von Methoden als Bezugspunkt der Designforschung aus einer rationalitätstheoretischen Perspektive. Im Fokus steht dabei zum einen die Überlegung, wie der Einsatz von kreativen und wissenschaftlichen Methoden den Gestaltungsprozess systematisiert und rationalisiert. Zum anderen geht es darum, wie die spezifischen Qualitäten von Designprozessen etablierte Verständnisse sowohl von Wissenschaft und Forschung als auch von Rationalität als solcher herausfordern. Mit Bezug auf konkrete Beispiele für Forschungsprojekte wird die Möglichkeit erkundet, inwieweit die pragmatisch formende Verhandlung eines methodischen (...) Vorgehens Designforschung mit der Kapazität ausstattet, einen Maßstab für selbstkritische Forschungspraxis zu aktualisieren. Es wird gezeigt, dass dieser Maßstab Implikationen für die philosophische Bestimmung gestalterischer und wissenschaftlicher Rationalität bereithält. Eine zentrale Rolle kommt dabei den externen und internen Grenzgebieten von Vernünftigkeit zu. (shrink)

This book represents an effort to understand very old questions about biological form, function, and the relationships between them. The essays collected here reflect the diversity of approaches in evolutionary developmental biology, including not only studies by prominent scientists whose research focuses on topics concerned with evolution and development, but also historically and conceptually oriented studies that place the scientific work within a larger framework and ask how it can be pushed further. Topics under discussion range from the use of (...) theoretical and empirical biomechanics to understand the evolution of plant form, to detailed studies of the evolution of development and the role of developmental constraints on phenotypic variation. The result is a rich and interdisciplinary volume that will begin a wider conversation about the shape of Evo Devo as it matures as a field. (shrink)

(2) Peter wollte Potsdam nicht verlassen bevor das Projekt in ruhigem Fahrwasser war. There are other well-known examples of non-interpreted negation, viz. cases of so-called negative concord in Slavic and Romance languages, but also in dialects of German and English. But arguably, in those cases the “superfluous” negation has to be present for grammatical reasons, which is not the case here. I will show that the negation is in fact interpreted, and that, due to a complex interplay of semantic and (...) pragmatic factors, we do get truth conditions for the two sentences that are not quite identical, but very similar.

In lieu of an abstract, here is a brief excerpt of the content:25. HUME'S ANTINOMIES I There are many contradictions in Hume. So much is readily admitted by all Hume scholars. But there is little agreement on what these contradictions show about Hume's thought in general. Many interpretations are based upon the view that Hume's contradictions are signs of his carelessness or lack of thoroughness. He is seen either as having lost all interest in giving a comprehensive or consistent account (...) of human nature or as not having pushed far enough his analysis of the philosophical problems facing him. Other interpretations suggest that Hume, the "skeptic," has recklessly introduced these contradictions in order to confuse us. He is perhaps not altogether serious and is laughing at those who take too serious a view of the "science" of metaphysics and his own contribution 2 to it. Others again argue that the contradictions (or some fundamental class of them) are the consequence of Hume's philosophical presuppositions or his psychological method. Given his particular beliefs and his method, these contradictions had to arise with logical necessity. However, the general opinion seems to be that, if Hume is not to be dismissed as a merely negative skeptic whose philosophy is of no great consequence, he needs to be excused or defended, i.e. his contradictions, which are 4 seen as "inconsistencies," have to be explained away. His discussions of the self, causality, substance, or the relationship of reason and the passions must be, and — it is believed — can be shown not to be contradictory, if all the relevant factors are considered. However, reconstructions of Hume's analysis of the self or causality, for instance, which involve the explaining away of contradictions soon find themselves in a rather peculiar quandary, since they also have to show that Hume's own admissions of the contradictory nature of his analysis is mistaken. Such "defenses" issue only in other 26. accusations, namely that Hume, in addition to not having expressed himself very clearly in his writings, failed to understand them himself when he referred back to them. If only for this reason, I think that interpretations which involve an explaining away or minimizing of the contradictions in Hume are suspect. It is my opinion that Hume needs no such defenses or excuses -- at least not in so far as the most important contradictions are concerned. On the contrary, I believe that Hume can be understood properly, only if we take full account of them. I want in this paper to argue that there is in Hume a fundamental class of contradictions which he believed were neither accidental nor created by his analysis, but were essential characteristics of the human mind. The contradictions uncovered by his analysis can be understood only if they are recognised as one aspect of a more complex problematic. They must have a "deeper" significance for Hume because they are the symptoms of the infirmities... which are common to human nature (T265). These are 'Hume's 7 "antinomies. " In this analysis I have allowed myself to be guided by a more or less Kantian conception of "antinomy" and "antinomical." In fact, I believe that there is a definite similarity between Kant's doctrine of the "Antinomy of Pure Reason" and Hume's "operations" which are equally natural and necessary in the human mind, yet in some circumstances... directly contrary (T266). But the present paper is not so much a sustained comparison of Hume and Kant in this regard as it is an attempt to elucidate the g peculiar nature of several contradictions in Hume. For I believe that, if we have a better understanding of the nature of these contradictions, we will also be able to say something more definite about Hume's theory of mental activity and certain aspects of the relationship of skepticism and naturalism (or: Pyrrhonism and Newtonianism, destructive and constructive side, negative and positive phase, etc.) in his thought. To this end, I shall first 27. explain what I mean by "antinomy" here. Secondly, I shall show in what sense Hume was aware of having discovered something very much like an antinomical dimension in human nature, and, finally, I shall offer some suggestions as to the relevance of this...

El tema del artículo es la teoría de la tarea del crítico, según un ensayo de W. Benjamin, titulado Dos poemas de Holderlin (1915). Los temas centrales son una fundamentación metafísica de la producción poética y su reproducción crítica. Esta segunda tarea siempre será para el lector crítico un experimento. El autor reconstruye la compleja teoría del cálculo poetológico de W. Benjamin, y pone como ejemplo de la tarea crítica dos versiones de un poema de Hölderlin sobre el tema "la (...) muerte del poeta". (shrink)

En la Convención internacional sobre los Derechos del Niño, el concepto del interés superior del niño es uno de sus principios rectores. Para comprenderlo como referente y posible impulso de actuación de niñas y niños, el autor analiza este principio en conjunto con otro principio que igualmente queda establecido por la Convención: el principio de la evolución de las facultades. Para relacionarlo con la vida real de las niñas y los niños, el autor explica, más allá de sus aspectos legales, (...) diferentes formas de entender este principio. Con referencia al enfoque de las “capabilidades” (capabilty approach), f inalmente hace hincapié no sólo en las condiciones de la evolución y del reconocimiento de las capacidades de niñas y niños sino también en las condiciones de su realización.
