SummaryA satisfactory analysis of the well‐known Hangman Paradox is not known to us. Two theses:1. The logical solution of the Hangman Paradox is easy and disappointing.2. The origins of the paradox are manifold and inexhaustible. We analyse particularly perspicuous tuneless version of the paradox due to Hollis .In a sequel which is to appear in Dialectica we analyse two versions of the original Hangman Paradox. Vorbemerkung: Der zweite Autor verdankt Henri Lauener menschlich und philosophisch mehr als dieser Artikel zeigen wird. (...) Es ist mir selten oder nie gelungen, Henri Lauener für eine meiner philosophischen Positionen zu pewinnen, aber ich glaube mich darin mit ihm einig, dass es sich lohnt, Formalismen ernst zu nehmen, um ihre Grenzen zu erkennen.

ZusammenfassungVagheit und Selbstreferenz sind die offensichtlichen Ursachen aller logico‐philosophischen Paradoxien. Beide Ursachen sind nur ein Stück weit formal zugänglich und führen uns über das Rätsel der mentalen Repräsentation/Partizipation/Produktion zuletzt zur unbegreiflichen Subjekt/Objekt‐Trennung. Die epistemischen Paradoxien vom Henker‐ Typ sind ein Labyrinth von Vagheit und Selbstreferenz. In Teil I analysierten wir eine zeitlose Variante von Hollis , in Teil II betrachten wir zwei klassische Henker Varianten.

This paper presents a framework of four types of meaning and understanding in the history of political thought and intellectual history. Previous frameworks have overlooked a whole type of meaning – the type often prioritised by political theorists and philosophers. I call this “extended meaning.” Correcting a wrong turn in philosophy of language in the 1950s, I show how extended meaning has robust intellectual foundations, and I illustrate its value for textual interpreters. Even historians often need extended meaning, for example (...) to help resolve ambiguous passages. So, the main types of meaning are not alternatives: scholars interested in one kind of meaning still need others. This paper thus celebrates both diversity and unity. (shrink)

The distinction between equality and sufficiency, much discussed in the distributive justice literature, is here applied to democratic theory. Overlooking this distinction can have significant normative implications, undermining some defences and criticisms of political equality, as I show by discussing the work of three prominent democratic theorists: Thomas Christiano, David Estlund, and Mark Warren. Most importantly, Christiano sometimes defends egalitarian conclusions using sufficientarian premises, or worries about inequality in situations where insufficiency is also part of the problem; inequality above the (...) level of sufficiency is not always as troubling. Estlund makes the reverse error. He attacks rather than defends political egalitarianism, but insufficiency seems to explain some of his concerns. Nonetheless, I show that political egalitarians may need to specify a sufficientarian threshold, to avoid levelling-down objections. Democratic theorists should thus take seriously the distinction between political equality and political sufficiency. More generally, political theorists and philosophers should be aware of omitted variable bias and interaction effects due to conceptual stretching arising from under-theorised distinctions in their thought experiments.

The Movement of Showing investigates the idea, shared by Derrida, Hegel and Heidegger, that the value of their thought is not found in its results or conclusions, but in its "movement." All three describe the heart of their work in terms of a pathway, development, or movement rather than in terms of its propositions or conclusions. This seems to deprive their thought of a solid ground, and indeed deconstruction in particular is often criticized in this way. Johan de Jong (...) argues that this is a structural vulnerability that is both its weakness and the source of its value, tracing Derrida's indirect method from his early to later works, and considering his engagements with Hegel and Heidegger. His analysis locates an affinity among Hegel, Heidegger and Derrida in a shared distrust of externality and, against the grain of some Levinasian commentaries, argues that Derrida's indirectness results in an ethics of complicity. The Movement of Showing answers a central question that many polemics about continental philosophy and postmodernism revolve around concerning how, methodologically, one can philosophize responsibly. It shows the difference between critique and polemics, and why simply taking up a position for or against is insufficient in order to think responsibly. (shrink)

Using fractal analyses to study events allows us to capture the scale-independence of those events, that is, no matter at which level we study a phenomenon, we should get roughly the same results because events exhibit similar structure across scales. This is demonstrably true in mathematical fractals but is less assured in behavioral fractals. The current research directly tests the scale-independence hypothesis in the behavioral domain by exploring the fractal structure of aggression, a social phenomenon comprising events that span temporal (...) scales from minutes of face-to-face arguments to centuries of international armed conflicts. Using publicly available data, we examined the temporal fractal structure of four scales of aggression: wars, riots, violent crimes, and body movement during arguments. Our results lend mixed support to the scale-independence hypothesis and provide insight into the self-organization of human interactions. (shrink)

This paper concentrates on some aspects of the history of the analytic-synthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, (...) that is, within the Classical Model of Science: scientific knowledge as cognitio ex principiis . But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them. (shrink)

Intellectual history is usually seen as essentially historical. It is – but it is also essentially philosophical, both when theorising intellectual history, which some intellectual historians do, and when interpreting texts, which all intellectual historians do. I demonstrate this symbiosis between history and philosophy via critical reflections on Martin Jay’s recent book Genesis and Validity. Philosophical analysis, closely integrated with historical examples, suggests that we should significantly rethink Jay’s theorisation of the relationship between genesis and validity (e.g. whether ideas from (...) one context are valid in others). But the symbiosis between history and philosophy matters more when interpreting texts. Philosophical analysis is a powerful tool for recovering what authors meant, understanding how their ideas fit together, and seeing similarities and differences between ideas, as I show with examples from Quentin Skinner’s interpretations of Machiavelli, Hobbes and others. Yet even Jay and Skinner – two of the world’s most philosophically astute intellectual historians – overlook the crucial symbiosis between history and philosophy. (shrink)

Among the many forms of research misconduct, publishing fraudulent data is considered to be serious where the confidence and validity of the research is detrimentally undermined. In this study, the trend of 303 retracted publications from 44 authors (with more than three retracted publications each) was analysed. The results showed that only 6.60% of the retracted publications were single-authored and the discovery of fraudulent publications had reduced from 52.24 months (those published before the year 2000) to 33.23 months (those published (...) on the year 2000 and onwards). It appears that with the widely accessible public databases like PubMed, fraudulent publications can be detected more easily. The different approaches adopted by authors who had previous publications retracted are also discussed herein. (shrink)

In this series of papers, I attempt to provide an answer to the question how the Babylonian scholars arrived at their mathematical theory of planetary motion. Paper I (de Jong in Arch Hist Exact Sci 73:1–37, 2019) was devoted to a study of system A theory of the outer planets. In this second paper, I will study system A theory of the planet Venus. All presently known ephemerides of Venus appear to have been written after 200 BC so that (...) the development of system A theory of Venus may have been a late development. On the other hand, there are several earlier texts in which the motion of Venus, going from one synodic phenomenon to the next one, is parametrized in quite some detail. At least six computational systems of Venus are known of which only two, systems A0 and A3, are genuine type-A systems. Both are based on the hypothesis that in exactly 1151 years Venus experiences 720 synodic phenomena of the same kind and that after this period of 1151 years Venus returns to exactly the same position in the sky. This period relation was probably derived from the observational fact that after 8 years Venus returns to a position in the zodiac that falls on average 2.5° short of its previous position. The study of the Babylonian planetary theory of Venus presented here will be primarily based on the system A3 theory of Venus because it is the most complete of the two systems. The parameters of the four step functions characterizing the system A3 model of the first and last appearances of Venus are known from previous studies of tablet BM 32599 (ACT 1050). Based on a database of synthetic observations of the first and last appearances (morning first, morning last, evening first and evening last) and the two stationary points (morning station and evening station) of Venus between 315 BC and 50 BC, I first discuss the observational material from the point of view of a Babylonian astronomer. This involves deriving synodic time intervals and synodic arcs from the observed dates and longitudes of Venus. Both vary with the position of Venus in the zodiac. This variation shows up most purely in the synodic arcs and synodic time intervals of Venus at its stations. The variation pattern of the synodic arcs and of the synodic time intervals at the first and last appearances of Venus differ considerably because they are strongly affected by atmospheric extinction and by the ecliptic latitude of Venus. A comparison of predictions of the first and last appearances of Venus computed according to system A3 with observations in the synthetic database shows that the models provide fairly accurate fits to the observations of evening last and morning first with typical standard deviations of about 2° but rather poor fits to the observations of morning last and evening first with typical standard deviations of about 7° and 4°. Quite surprisingly, it turns out that the morning first A3 model fits the observed longitudes of Venus at its stations almost perfectly, with standard deviations of about 1°. This suggests that observations of the stations of Venus must have been available to the Babylonian astronomer(s) who constructed the system A3 model of Venus and who computed the longitudes of Venus at its first and last appearances preserved in tablet BM 32599. This is quite puzzling because observations of the stations of Venus were definitely not part of the standard observing program of the Babylonian astronomers as we know it from the Astronomical Diaries. To resolve this problem, I propose that observations could have been made by some individual astronomer for his own use but that these observations never became part of the tradition of what was regularly observed and recorded in the Astronomical Diaries. It turns out that 25 years of observations of Venus (here illustrated for the years 203 BC to 178 BC) is sufficient for the construction of a system A model that perfectly fits the variation of the synodic arcs of Venus at its stations. By combining observed time intervals and known velocities of Venus, observations over this limited timespan can also be used to construct longitudes of Venus at its first and last appearances from previous known positions of Venus based on Normal Stars passages or from known positions at its stations. This is the only way in which positions of Venus at its first and last appearances can be determined because at its first and last appearances the sky is too bright for Normal Stars to be visible. I propose that the Babylonian system A3 models of Venus were based on longitudes constructed in this way. I finally suggest that the tablet, of which BM 32599 is the remainder, was filled line by line starting with a set of initial values in the bottom left-hand corner of the tablet and that the choice of these initial values was based on an observation of Venus at its evening station when it was exceptionally close to the Normal Star η Piscium in February 179 BC. Based on this choice of initial conditions, the tablet covers the years 403 BC to 170 BC and it may have been composed around 170 BC. It was probably computed with the purpose of creating a raster of longitudes with mazes of about 2.5° that could be used to predict future positions of Venus at its first or last appearance once a position at a previous first or last appearance was available.

Prenatal screening for foetal abnormalities such as Down's syndrome differs from other forms of population screening in that the usual aim of achieving health gains through treatment or prevention does not seem to apply. This type of screening leads to no other options but the choice between continuing or terminating the pregnancy and can only be morally justified if its aim is to provide meaningful options for reproductive choice to pregnant women and their partners. However, this aim should not be (...) understood as maximizing reproductive choice per se. Only if understood as allowing prospective parents to avoid suffering related to living with (a child with) serious disorders and handicaps can prenatal screening be a publicly or collectively funded programme. The alternative of moving prenatal testing outside the healthcare system into the private sector is problematic, as it makes these tests accessible only to those who can afford to pay for it. New developments in prenatal screening will have to be assessed in terms of whether and to what extent they either contribute to or undermine the stated aim of providing meaningful options for reproductive choice. In the light of this criterion, this article discusses the introduction of the new non‐invasive prenatal test (NIPT), the tendency to widen the scope of follow‐up testing, as well as the possible future scenarios of genome‐wide screening and ‘prenatal personalised medicine’. The article ends with recommendations for further debate, research and analysis. (shrink)

The need for urgent, structural transformations to dominant food systems is increasingly recognized in research and policy. The direction these transformations take is in great part influenced by how the problem is framed and what future pathways become seen as plausible and desirable. Scientific knowledge and the organizations producing it hold considerable authority in suggesting what alternatives are or are not worth pursuing, ultimately shaping frames and in turn being shaped by them. This paper examines Brazil’s federal Agricultural Research Corporation (...) (Embrapa), a major contributor to technological advances that made Brazil into an agricultural powerhouse. We examine the ways in which Embrapa’s leadership has framed sustainable agriculture in its public communication and the wider implications for food systems transformation. Drawing from Embrapa news articles in the period 2015–2020, we identify four interrelated frames forming Embrapa’s prevalent position on sustainability. Our results show that while Embrapa promotes practices based on alternative approaches such as agroecology, its deeper framing often reflects the core assumptions driving dominant industrial food systems. This framing reinforces underlying logics of control, efficiency, and competition aligned with the productivist paradigm and excludes divergent perspectives that exist within the organization.

In this series of papers I attempt to provide an answer to the question how the Babylonian scholars arrived at their mathematical theory of planetary motion. Papers I and II were devoted to system A theory of the outer planets and of the planet Venus. In this third and last paper I will study system A theory of the planet Mercury. Our knowledge of the Babylonian theory of Mercury is at present based on twelveEphemeridesand sevenProcedure Texts. Three computational systems of (...) Mercury are known, all of system A. System A1is represented by nineEphemeridescovering the years 190 BC to 100 BC and system A2by twoEphemeridescovering the years 310 to 290 BC. System A3is known from aProcedure Textand from Text M, anEphemerisof the last evening visibility of Mercury for the years 424 to 403 BC. From an analysis of the Babylonian observations of Mercury preserved in theAstronomical DiariesandPlanetary Textswe find: (1) that dates on which Mercury reaches its stationary points are not recorded, (2) that Normal Star observations on or near dates of first and last appearance of Mercury are rare (about once every twenty observations), and (3) that about one out of every seven pairs of first and last appearances is recorded as “omitted” when Mercury remains invisible due to a combination of the low inclination of its orbit to the horizon and the attenuation by atmospheric extinction. To be able to study the way in which the Babylonian scholars constructed their system A models of Mercury from the available observational material I have created a database of synthetic observations by computing the dates and zodiacal longitudes of all first and last appearances and of all stationary points of Mercury in Babylon between 450 and 50 BC. Of the data required for the construction of an ephemeris synodic time intervals Δt can be directly derived from observed dates but zodiacal longitudes and synodic arcs Δλ must be determined in some other way. Because for Mercury positions with respect to Normal Stars can only rarely be determined at its first or last appearance I propose that the Babylonian scholars used the relation Δλ = Δt −3;39,40, which follows from the period relations, to compute synodic arcs of Mercury from the observed synodic time intervals. An additional difficulty in the construction of System A step functions is that most amplitudes are larger than the associated zone lengths so that in the computation of the longitudes of the synodic phases of Mercury quite often two zone boundaries are crossed. This complication makes it difficult to understand how the Babylonian scholars managed to construct System A models for Mercury that fitted the observations so well because it requires an excessive amount of computational effort to find the best possible step function in a complicated trial and error fitting process with four or five free parameters. To circumvent this difficulty I propose that the Babylonian scholars used an alternative more direct method to fit System A-type models to the observational data of Mercury. This alternative method is based on the fact that after three synodic intervals Mercury returns to a position in the sky which is on average only 17.4° less in longitude. Using reduced amplitudes of about 14°–25° but keeping the same zone boundaries, the computation of what I will call 3-synarc system A models of Mercury is significantly simplified. A full ephemeris of a synodic phase of Mercury can then be composed by combining three columns of longitudes computed with 3-synarc step functions, each column starting with a longitude of Mercury one synodic event apart. Confirmation that this method was indeed used by the Babylonian astronomers comes from Text M (BM 36551+), a very early ephemeris of the last appearances in the evening of Mercury from 424 to 403 BC, computed in three columns according to System A3. Based on an analysis of Text M I suggest that around 400 BC the initial approach in system A modelling of Mercury may have been directed towards choosing “nice” sexagesimal numbers for the amplitudes of the system A step functions while in the later final models, dating from around 300 BC onwards, more emphasis was put on selecting numerical values for the amplitudes such that they were related by simple ratios. The fact that different ephemeris periods were used for each of the four synodic phases of Mercury in the later models may be related to the selection of a best fitting set of System A step function amplitudes for each synodic phase.

Until recently, the notions of function and multiple realization were supposed to save the autonomy of psychological explanations. Furthermore, the concept of supervenience presumably allows both dependence of mind on brain and non-reducibility of mind to brain, reconciling materialism with an independent explanatory role for mental and functional concepts and explanations. Eliminativism is often seen as the main or only alternative to such autonomy. It gladly accepts abandoning or thoroughly reconstructing the psychological level, and considers reduction if successful as equivalent (...) with elimination. In comparison with the philosophy of mind, the philosophy of biology has developed more subtle and complex ideas about functions, laws, and reductive explanation than the stark dichotomy of autonomy or elimination. It has been argued that biology is a patchwork of local laws, each with different explanatory interests and more or less limited scope. This points to a pluralistic, domain-specific and multi-level view of explanations in biology. Explanatory pluralism has been proposed as an alternative to eliminativism on the one hand and methodological dualism on the other hand. It holds that theories at different levels of description, like psychology and neuroscience, can co-evolve, and mutually influence each other, without the higher-level theory being replaced by, or reduced to, the lower-level one. Such ideas seem to tally with the pluralistic character of biological explanation. In biological psychology, explanatory pluralism would lead us to expect many local and non-reductive interactions between biological, neurophysiological, psychological and evolutionary explanations of mind and behavior. This idea is illustrated by an example from behavioral genetics, where genetics, physiology and psychology constitute distinct but interrelated levels of explanation. Accounting for such a complex patchwork of related explanations seems to require a more sophisticated and precise way of looking at levels than the existing ideas on (reductive and non-reductive) explanation in the philosophy of mind.

This paper analyses the relationship between Hobbes's theory of language and his theory of science and method. It is shown that Hobbes, at least in his Computatio sive Logica (1655), deviates in some measure from the traditional (Aristotelian) model of language. In this model speech is considered to be a fairly unproblematic expression of thought, which itself is independent of language. Basing himself on a nominalist account of universals, Hobbes states that the demonstration or assertion of universal propositions presupposes speech (...) (more especially, the use of names as marks). This insight turns out to be essential for Hobbes's (rationalist) view of scientific method. (shrink)

Medical missionaries made a breakthrough in Korean history in healing and caring for many Hansen and tuberculosis patients. There was a missionary who had no less good influence than medical missionaries at this time. The person is missionary Sarah Barry, who inspired and developed one of the most influential student movements in South Korea. The aim of the present study is to examine life of Sarah Barry and her ministry, focusing upon her positive influences on Korean intellectuals. The relevance of (...) the study is conditioned by the fact that there is no professional academic research on her ministry except for one short paper, which discusses the importance of her role in formulating campus evangelism. In order to achieve the aim of the study, the method of analysis and synthesis of biographical and historical data was used. As a result of the study, Sarah Barry’s biography was researched and systematized. It gave ground to a conclusion that her role in South Korea’s gradual resurgence after the Civil War was seminal.

ABSTRACT In this article, we will first give a historic overview of the concept of benefit sharing and its appearance in official agreements, particularly with respect to crop genetic resources. It will become clear that, at present, benefit sharing is primarily considered as an instrument of compensation or exchange, and thus refers to commutative justice. However, we believe that such a narrow interpretation of benefit sharing disregards, and even undermines, much of its (historical) content and potency, especially where crop genetic (...) resources are concerned. We argue that benefit sharing should not be based merely on commutative justice but rather on a broader model that is also grounded in the concept of distributive justice. This has repercussions for the application of benefit sharing, which we try to clarify by distinguishing between downstream and upstream benefit sharing. Upstream benefit sharing is not so much inspired by compensation for actions done, or the distribution downstream of benefits developed, but by the idea of shared decision‐making on the research and development of resources fundamental to human welfare. Going upstream in the research process of crop genetic resources, and determining research agendas and improving crops according to the needs of the poor, benefit sharing may well be a tool to contribute to world food security and global justice. We concretize our ideas on upstream benefit sharing by introducing a set of criteria that determine the success of consultations on agricultural research agenda setting. (shrink)
