Modern commentators have doubts about the authenticity and cogency of the early propositions of Archimedes’ On Equilibrium of Planes Book 1. Ernst Mach famously said that the proof of Prop. 6, the so-called law of the lever, assumes what is to be proven. Comparing the initial text in Heiberg’s modern edition (1881, 1913) to the first propositions in Eutocius’ commentary on EP 1, J. L. Berggren ([1976]. ‘Spurious Theorems in Archimedes’ Equilibrium of Planes: Book I’, Archive for History of Exact (...) Sciences 16.2 (1976), 87–103.) claimed that the propositions up through Proposition 3 of the standard modern edition are schoolbook additions written by an ancient author inferior to Archimedes. The present paper argues for the logical connectedness of Postulates 1–5 to Props. 1–6, by means of a detailed examination of the course of the argument and a re-examination of Eutocius’ remarks. The paper reinterprets the role of the empirical in the early propositions and offers a reading of the contribution of Archimedes’ mechanics to the method of EP 1. (shrink)

Background Citizen science and models for public participation in health research share normative ideals of participation, inclusion, and public and patient engagement. Academic researchers collaborate in research with members of the public involved in an issue, maximizing all involved assets, competencies, and knowledge. In citizen science new ethical issues arise, such as who decides, who participates, who is excluded, what it means to share power equally, or whose knowledge counts. This article aims to present an ethics framework that offers a (...) lens of understanding and heuristic guidelines to deal with ethical issues in citizen science. -/- Methods We conducted seven case studies between 2015 and 2021 to attune and validate the ethics framework for the context of citizen science. The cases related to studies with older adults, people with a psychiatric vulnerability, people dependent on community care, people who are unemployed or living in poverty or both, and young adults with respiratory disease. -/- Results Ethics in citizen science reaches beyond the ethical issues in traditional biomedical and health research. It entails more than following procedures about informed consent and privacy and submitting a proposal to a Medical Research Ethics Committee. Ethics in citizen science relates to everyday ethical issues during the study, including relational and moral complexities concerning collaboration, sharing power, and democratic decision-making. Dealing with these issues requires ethics work of researchers. This entails seeing ethically salient issues and reflecting on everyday ethical issues. Ethics work consists of seven features: framing work, role work, emotion work, identity work, reason work, relationship work, and performance work. All are relevant for researchers in citizen science. -/- Conclusions Ethical issues in citizen science often relate to power differentials, partnership, and collaboration between academics and non-academics. The ethics framework prepares researchers for the work needed in citizen science to act responsibly and offers a heuristic guide to reflect on ethics. Reflection on ethics is a pathway towards ethical citizen science, especially if researchers collaboratively reflect in partnership with non-academics who are subject to the moral issue. (shrink)

While no classicist would deny that Quintilian’s “Institutio oratoria” is the most complete handbook of rhetoric transmitted from Antiquity, the work is usually mined for its information on both the Roman educational system and technical aspects of the art of speaking. The “Institutio” may be useful as a guide to eloquence, but its author frequently hints to higher aspirations. This article focuses on the literary merits of the “Institutio”, arguing that it deliberately competes with the poetical works of Horace, Vergil, (...) and, possibly, Statius. (shrink)

We discuss the nature of reality in the ontological context of Penrose’s math-matter-mind triangle. The triangle suggests the circularity of the widespread view that math arises from the mind, the mind arises out of matter, and that matter can be explained in terms of math. Non-physicists should be wary of any claim that modern physics leads us to any particular resolution of this circularity, since even the sample of three theoretical physicists writing this paper hold three divergent views. Some physicists (...) believe that current physics has already found the basic framework for a complete description of reality, and only has to fill in the details. Others suspect that no single framework, from physics or other sources, will ever capture reality. Yet others guess that reality might be approached arbitrarily closely by some form of future physics, but probably based on completely different frameworks. We will designate these three approaches as the fundamentalist, secular and mystic views of the world, as seen by practicing physicists. We present and contrast each of these views, which arguably form broad categories capturing most if not all interpretations of physics. We argue that this diversity in the physics community is more useful than an ontological monoculture, since it motivates physicists to tackle unsolved problems with a wide variety of approaches.

The rise of Big Data changes the context in which organisations producing official statistics operate. Big Data provides opportunities, but in order to make optimal use of Big Data, a number of challenges have to be addressed. This stimulates increased collaboration between National Statistical Institutes, Big Data holders, businesses and universities. In time, this may lead to a shift in the role of statistical institutes in the provision of high-quality and impartial statistical information to society. In this paper, the changes (...) in context, the opportunities, the challenges and the way to collaborate are addressed. The collaboration between the various stakeholders will involve each partner building on and contributing different strengths. For national statistical offices, traditional strengths include, on the one hand, the ability to collect data and combine data sources with statistical products and, on the other hand, their focus on quality, transparency and sound methodology. In the Big Data era of competing and multiplying data sources, they continue to have a unique knowledge of official statistical production methods. And their impartiality and respect for privacy as enshrined in law uniquely position them as a trusted third party. Based on this, they may advise on the quality and validity of information of various sources. By thus positioning themselves, they will be able to play their role as key information providers in a changing society. (shrink)

Superstars are not by accident a conspicuous phenomenon in our culture, but inherently belong to a meritocratic society with mass media, free enterprise, and competition. To make this contention plausible I will use Caillois's book, Man, Play and Games, to compare the mechanisms underlying the superstar phenomenon with a special kind of game, as set out by Caillois. As far as I know, Caillois's book is not quoted in the literature dealing with income distribution theories, although the comparison with play (...) and games is, for limited purposes, interesting. In play and games we find almost all elements which play a role in theories of just income distribution: equality of opportunity, chance, talent, competition and skill, reward, entitlement, winners and losers, etc. These are not chance similarities, for “… games are largely dependent upon the cultures in which they are practised. They affect their preferences, prolong their customs, and reflect their beliefs … One … can … posit a truly reciprocal relationship between a society and the games it likes to play”. Moreover, as we will see, superstars combine the four basic characteristics of play that make their activities a special kind of play. (shrink)

Betoog over de waarde van het zien i.t.t. het kijken. De kern van dit non-duale en onmiddellijke zien is dat je 'bent wat je ziet', een soort Schlüssel- of grenservaringen die tot een woordeloze wijsheid leiden en alle vanzelfsprekendheden laten vervagen.

This essay discusses whether an indigenous African ethic, as expressed in ubuntu, may serve as an example of how to decolonise Western knowledge. In the first part, the key claims of decolonisation of knowledge are set out. The second part analyses three strategies to construct models of ‘African’ ethics, namely transfer, translation and stating of a substantive rival model as contained in ubuntu ethics. After a critical appraisal of this substantive proposal, part three indicates the potential and limitation of the (...) decolonisation project: possibilities lie in the -contextualisation of knowledge, whereas limitations are related to constructing an alternative to what is known as ‘scientific’ knowledge. As far as the author knows, this is the first attempt to frame ethics in terms of the epistemological search for ‘decolonised’ knowledge. (shrink)

After the presentation of different views on the relation between narrative and life it is argued that Paul Ricoeur's view offers a framework that allows an answer to questions that remain unanswered in the work of MacIntyre and Carr. Although Ricoeur's view has its own flaws, the concepts of triple mimesis and of narrative identity can be incorporated in a post-foundationalist view. Within this resulting frame of reference narratives in narrative research are interpreted as compositions, as the result of emplotment. (...) Thus the characteristics of a narrative apply to the participant's stories, to personal identity and to the researcher's narrative. (shrink)

Since we cannot put stars in a laboratory, astrophysicists had to wait till the invention of computers before becoming laboratory scientists. For half a century now, we have been conducting experiments in our virtual laboratories. However, we ourselves have remained behind the keyboard, with the screen of the monitor separating us from the world we are simulating. Recently, 3D on-line technology, developed first for games but now deployed in virtual worlds like Second Life, is beginning to make it possible for (...) astrophysicists to enter their virtual labs themselves, in virtual form as avatars. This has several advantages, from new possibilities to explore the results of the simulations to a shared presence in a virtual lab with remote collaborators on different continents. I will report my experiences with the use of Qwaq Forums, a virtual world developed by a new company. (shrink)

The book argues that mainstream economists, who base their analyses only on the economic motivation of people, fail to explain and understand real-life economic phenomena. The economic crisis, which began in 2008, illustrates the relevance of psychic and social motivations, especially when combined with each other. This book discusses orthodox and heterodox economics, and offers the reader ample material on philosophy of science, psychology and sociology. A multidisciplinary economic perspective is constructed in which economics, psychology, and sociology are integrated, and (...) this multidisciplinary approach offers an understanding of real-life problems. Moreover, it offers researchers a rich source for further analysis. (shrink)

Since the emergence of neo-evolutionism in the 1960s, various critiques of the theory of social or socio-cultural evolution have been forwarded, including notably those of Immanuel Wallerstein, Alain Touraine and Anthony Giddens who decisively reject the idea of evolution. Within this context, Jürgen Habermas's theory of socio-cultural evolution has also become a specific object of critique, the best known in the English-speaking world being, perhaps, Michael Schmid's critique. While the latter is ultimately based on neo-Darwinistic assumptions which allow a non-Marxist (...) alternative to be pitted against Habermas's position, a significant immanent critique has been taking shape during the late 1970s and 1980s the contours of which are at present starting to become visible, despite the fact that as yet it is nowhere developed and presented in a systematic manner. I have in mind here the work of younger authors belonging to the circle around Habermas, such as Johann Arnason, Axel Honneth, Hans Joas, Günter Frankenberg, Ulrich Rödel, and Klaus Eder, who have not only developed a critique of Habermas but are also engaged in developing an alternative to him within the framework of critical theory.

The political philosopher Hannah Arendt develops several arguments regarding why truthfulness cannot be counted among the political virtues. This article shows that similar arguments apply to lying in business. Based on Hannah Arendt's theory, we distinguish five reasons why lying is a structural temptation to businessmen: business is about action to change the world and therefore businessmen need the capacity to deny current reality; commerce requires successful image-making and liars have the advantage to come up with plausible stories; business communication (...) is more often about opinions than about facts, giving leeway to ignore uncomfortable signals; business increasingly makes use of plans and models, but these techniques foster inflexibility in acknowledging the real facts; and businessmen easily fall prey to self-deception, because one needs to act as if the vision already materializes. The theory is illustrated by a case study of Landis, which grew from a relatively insignificant organization into a large one within a short period of time, but ended with outright lies and bankruptcy.

The article represents auto-ethnographical reflections about the author's journey towards reconciling diversity with the advent of democracy in South Africa. The author recounts aspects of his participation in the Truth and Reconciliation Commission. It focuses on aspects of Reformed theology and spirituality as instruments for reconciling diversity. Local and international theologians opposed apartheid, calling it an unjust and indefensible political system, using their Reformed conviction, often applying the very same notions and principles. The article discusses the opposition to apartheid in (...) the Reformed world, which culminated during the Ottawa meeting of the World Alliance of Reformed Churches in 1982 when apartheid was denounced as a 'sin and a heresy' - a legitimate cause for a Status Confessionisin a classical Reformed manner. The article demonstrates the way in which the TRC took note of all of this and includes testimonies of Reformed theologians and leaders who opposed apartheid, often paying a costly price. (shrink)

Adrianus van Selms as protestantse Teoloog. Van Selms het in 1938 vanaf Nederland na Suid-Afrika toe gekom om Semitiese Tale te doseer in die Fakulteit Lettere en Wysbegeerte aan die Universiteit van Pretoria. Hy het ook deeltyds in die Fakulteit Teologie doseer. Die Universiteit van Pretoria het hom as een van denkleiers van die 20ste eeu aan die universiteit erken. Hy het geslagte van teologiese studente beïnvloed tydens sy amptelike dienstydperk aan die universiteit, vanaf 1938 tot 1971. Meer as 300 (...) publikasies staan agter sy naam. Behalwe vir werk wat hy op die terrein van die Semitiese Tale gelewer het, het hy ook verskeie kommentare oor Ou-Testamentiese boeke geskryf. Verder was hy ook aktief as prediker in die kerk en het ook 'n uitsonderlike bydrae tot die kategesemateriaal van die Kerk gelewer. As teoloog het Van Selms aansluiting gevind by die reformatoriese tradisie van die 16de eeu. As eksegeet het hy die uitdaging aanvaar om die Bybelse tekste te lees in die erkenning van die historiese afstand wat die hedendaagse leser van die oorspronklike tekste skei. Hy is sodoende gekonfronteer met die knaende probleem van die benadering tot die Bybelse tekste: dogmaties of histories-krities? Deur as eksegeet sy eie dogmatikus te word, het hy die twee benaderings nie apart gehou nie, maar tot 'n eenheid gebring en op die manier 'n hervorming in die beoefening van die teologie verteenwoordig. Hy aanvaar met hierdie werkswyse die verantwoordelikheid vir die erfenis van die Kerkhervorming vir die kerk van sy dag. Die hoofstuk ontwikkel langs die verwagtinge wat aan die amp van predikant in die reformatoriese tradisie gestel word: teologie, prediking, kategese en herdelike sorg. (shrink)

This paper argues that an African business ethic should take the promotion of cultural justice as one of its major tasks. After an explanation of globalisation as homogenizing cultural force that shapes moral identity, the notion of cultural justice as "unselfconscious living" is explained. This is then set in the context of an agenda for business ethics in Africa that would require more work on how a narrative moral identity is constructed, and how trans-cultural business environments could be created and (...) sustained.

Instead of speaking of conscious experience as arising in a brain, we prefer to speak of a brain as arising in conscious experience. From an epistemological standpoint, starting from direct experiences strikes us as more justified. As a first option, we reconsider the ‘hard problem’ of the relation between conscious experience and the physical world by thus turning that problem upside down. We also consider a second option: turning the hard problem sideways. Rather than starting with the third-person approach used (...) in physics, or the first- person approach of starting with individual conscious experience, we consider starting from an I-and-you basis, centered around the second-person. Finally, we present a candidate for what could be considered to underlie conscious experience: ‘sense’. We consider this to be a shot in the dark, but at least a shot in the right direction: somewhere between upside down and sideways. Our notion of sense can be seen as an alternative to panpsychism. To give an analogy, using the notions of space and time is more convenient than trying to analyse the phenomenon of motion in terms of a space-based ‘pandynamism’. Similarly, when approaching the phenomenon of consciousness, we prefer the triad of space, time and sense, over a spacetime-based form of panpsychism. (shrink)

This paper seeks to show that the proposition of 'double contingency' introduced by Parsons and defended by Luhmann and Habermas is insufficient under the conditions of contemporary communication societies. In the latter context, the increasing differentiation and organization of communication processes eventuated in the recognition of the epistemic authority of the public, which in turn compels us to conceptualize a new level of contingency. A first step is therefore taken to capture the role of the public in communication societies theoretically (...) by what may be called 'triple contingency'. Since the process of the definition of reality and its outcome, to which the response of the public is central, is best seen in constructivist terms, attention is also paid to relevant methodological and epistemological questions. Key Words: cognitive turn • communication • constructivism • double contingency • Habermas • Luhmann • observation • Parsons • situationalism • the third point of view. (shrink)

Responding to a call for systematic contributions on the theory of society, the principle aim of this article is to recover and reconstruct the Young-Hegelian core of critical theory’s theory of the dialectical development of society and, on that basis, to project its creative research-based continuation by analysing its largely neglected key concept of possibility. The acknowledgement of the critical theory lineage’s naturalist, realist and especially idealist features leads this reconstruction to ascribe a central role to certain pivotal concepts that (...) deserve special attention – including nature, the construction of society, evolution, immanent–transcendence and the conceptual conditions or cognitive order of society. A side effect of this theoretical exposition is the exposure in the course of the argument of certain weaknesses often visible in the contemporary articulation of the theory of society in both critical theory and general social theory. Conceptual solutions to those deficiencies are simultaneously presented in a form appropriate to critical theory’s modal-based negative explanatory and positive disclosing critique. (shrink)
