Protophysics and Special Theory of Relativity. First, a proposal for a constructive foundation of the Special Theory of Relativity by M. Buth is criticized and confronted with an alternative proposal by the author. The main idea is to solve the problem of transforming coordinates between inertial systems in terms of the General Theory of Measurement. Regarding transformations of co-ordinates as transformations of thecorresponding “functions of measurement” these functions have to meet two demands. 1. To identify measured values which are related (...) to different inertial systems and measuring procedures as the same magnitude, the ratio scale of length and duration has to be defined with respect to the whole class of inertial systems. 2. Using the concept of a certain physical magnitude, propositions about measuring devices are made which are invariant with respect to measuring procedures. As aconsequence every transformation between functions of measurement has to be an equivalence relation. The first demand leads to linearity, the second one reduces the set of permissible transformations between inertial systems to the alternative of Galilei- and Lorentz-transformation. The (im)possibility of putting an absolute simultaneity into practice decides between these transformations. (shrink)

Biomedical and social scientists are increasingly calling the biological sex into question, arguing that sex is a graded spectrum rather than a binary trait. Leading science journals have been adopting this relativist view, thereby opposing fundamental biological facts. While we fully endorse efforts to create a more inclusive environment for gender‐diverse people, this does not require denying biological sex. On the contrary, the rejection of biological sex seems to be based on a lack of knowledge about evolution and it champions (...) species chauvinism, inasmuch as it imposes human identity notions on millions of other species. We argue that the biological definition of the sexes remains central to recognising the diversity of life. Humans with their unique combination of biological sex and gender are different from non‐human animals and plants in this respect. Denying the concept of biological sex, for whatever cause, ultimately erodes scientific progress and may open the flood gates to “alternative truths.”. (shrink)

v. 1. History of linguistics.--v. 2. Contemporary linguistics.

It has frequently been observed that typical utterances of the form “I believe that P” are assertions of the embedded proposition P. Yet that the matrix clause “I believe that” should be semantically idle creates an interesting puzzle: linguistic orthodoxy holds that the utterance is an assertion about one’s doxastic state, not about the content of this state. In response to the puzzle, Tim Henning has recently proposed a new semantic theory, parentheticalism, according to which “S believes that P” expresses (...) P from S’s point of view: the at-issue content in belief ascriptions is the embedded proposition P. The puzzle is then claimed to be resolved as follows: as speaker and doxastic subject are identical in the first-person case, “I believe that P” expresses P from the speaker’s own point of view. In this paper, I argue, first, that parentheticalism is highly doubtful and, second, that even if parentheticalism were true, it would be unable to resolve the transparency puzzle. (shrink)

Wolfgang Huber is Germany's most important theological ethicist, and this is a translation of his 2013 book published with CH Beck. Acknowledging our pluralistic world, Huber analyzes twenty ethical issues that emerge during the course of our lives: the future of the family, genetic handicaps and genetic enhancement, combatting global hunger and poverty, environmental degradation, religious freedom, the right to health, the expanding influence of the media, the true purpose of business, what we owe our descendants, global conflict and (...) war and peace, the role of science, extending life and accepting death, and so on. In each chapter he provides a concrete example showing the relevance of the fundamental ethical question, then explains how one can think through possible responses and reactions. Huber is firmly within the Protestant tradition and takes philosophical cues from Kant. As such, he emphasizes the connections between personal, professional, and institutional ethics and demonstrates how human relationships lie at the center of our ethical lives. His aim is to articulate a theology of what he calls "responsible freedom" that transcends individualistic self-realization and includes communal obligations. (shrink)

Dieser Essay behandelt das Phanomen der doppelten Belastung von Frauen, die zugleich "ihren" Haushalt in Ordnung halten und einem "normalen" Beruf nachgehen (wollen/miissen).Er konzentriert sich auf zwei Seiten einer dialektischen Situation: einmal das naheliegende Faktum, daB eine zweifache Belastung die Arbeitshetze intensiviert, den StreB intensiviert und die freie Zeit so weit "auffriBt", daB ein humanes Leben ausgeschlossen bleibt: die Not der Tugend; zum andern der weniger leicht zugangliche, gleichwohl reale Sachver halt, daB Belastungen auch Herausforderungen darstellen, Bewiih rungs proben mit (...) der Chance zu personlicher Entwicklung und strate gischer Entfaltung: die Tugend der Not. Beide Seiten gehOren untrennbar zusammen. Wie ihr Verhaltnis im einzel nen verlauft, ist eine offene Frage. Vermutlich folgt es jener "Laffer-Kur ve", die einige Zeit lang in der wirtschaftswissenschaftlichen Diskussion eine Rolle spielte: d.h., bis zu einem gewissen Maximum fordern zusatzli che Belastungen die Entfaltung der Personlichkeit; was dariiber hinausgeht, lost regressive Veranderungen aus. Den Umschlagpunkt galte es theoretisch zu bestimmen und praktisch zu stabilisieren. (shrink)

Zodiacal and Planetary ‘decani’. The 36 ecliptical ‘decani’ (sectors of 10°) were distributed either to the twelve zodiacal signs or to the seven planets. The first system has been transmitted only by the Roman didactic poet Manilius, who commits an error at the end of his catalogue that can be explained by comparing it with the more frequent planetary one. Both systems follow the Roman calendar beginning with the Ram respectively Mars. Although the zodiacal system (36 : 12) runs without (...) remainder whereas the planetary one (36 : 7) repeats Mars once more (six times), so that it both begins and ends with this planet, this planetary system prevails. Four possible astrological reasons of this contradiction are discussed including other texts, mostly taken from the ‘Babylonian’ Teucrus (at the latest first century BC), who represents the first witness, if not the inventor of this particular lore.

Meets what? Ranking theory is, as far as I know, the only existing theory suited for underpinning Keith Lehrer’s account of knowledge and justification. If this is true, it’s high time to bring both together. This is what I shall do in this paper. However, the result of defining Lehrer’s primitive notions in terms of ranking theory will be disappointing: justified acceptance will, depending on the interpretation, either have an unintelligible structure or reduce to mere acceptance, and in the latter (...) interpretation knowledge will reduce to true belief. Of course, this result will require a discussion of who should be disappointed. So, the plan of the paper is simple: In section 1 I shall briefly state what is required for underpinning Lehrer’s account and why most of the familiar theories fail to do so. In section 2 I shall briefly motivate and introduce ranking theory. Basing Lehrer’s account on it will be entirely straightforward. Section 3 proves the above-mentioned results. Section 4, finally, discusses the possible conclusions. (shrink)

Maybe human aesthetics developed from animal aesthetics. I am not, of course, suggesting that sophisticated aesthetics as practiced by humans already exists among animals. Yet the aesthetic attitude as such might have originated in the animal kingdom. Drawing on this animal resource, human aesthetics might have evolved and, when cultural evolution emerged, it had reached results very different from animal aesthetics. With this perspective in mind, I show that the evolutionary aesthetics, as commonly pursued today, falls prey to serious shortcomings.

Neue Entwicklungen der Medizin haben die Entscheidung über Geburt und Tod wie nie zuvor in die Hände des Menschen gelegt. Damit stellen sich schwerwiegende Fragen: Welcher Embryo darf überleben? Wie lange darf ein Leben über das Erträgliche hinaus verlängert werden? Weltweite soziale Konflikte führen zu der Forderung, in Verantwortung für den Frieden notfalls Waffengewalt einzusetzen. Mit Klimawandel und Staatsverschuldung verbinden sich neue ökologische, soziale und politische Probleme. Wolfgang Huber erklärt, in welcher Weise die aktuellen Herausforderungen uns alle angehen, und (...) formuliert Maßstäbe des Menschlichen für ihre Lösung. Sein Buch ist ein wunderbar klar geschriebenes Vademecum der Ethik, das uns die wirklich wichtigen Fragen unseres Lebens bewusst macht. "Das Buch ist ein weiser Führer durch die ethischen Lebensprobleme der Einzelnen und der Gesellschaften heute." Karl Kardinal Lehmann "Wolfgang Huber und mich verbindet immer das Empfinden eines elementaren Zusammenhanges zwischen christlichem Bekenntnis und politischer Verantwortung."
