RAAAF [Rietveld Architecture-Art-Affordances] is an interdisciplinary studio that operates at the crossroads of visual art, experimental architecture and philosophy. RAAAF makes location- and context-specific artworks, an approach that derives from the respective backgrounds of the founding partners: Prix de Rome laureate Ronald Rietveld and Socrates Professor in Philosophy Erik Rietveld.

Here, Rhonda Martens offers the first extended study of Kepler's philosophical views and shows how those views helped him construct and justify the new astronomy.

A common adage runs that, given a theory manifesting symmetries, the syntax of that theory should be modified in order to construct a new theory, from which symmetry-variant structure of the original theory has been excised. Call this strategy for explicating the underlying ontology of symmetry-related models reduction. Recently, Dewar has proposed an alternative to reduction as a means of articulating the ontology of symmetry-related models—what he calls sophistication, in which the semantics of the original theory is modified, and symmetry-related (...) models of that theory are treated as if they are isomorphic. In this paper, we undertake a critical evaluation of sophistication about symmetries—we find the programme underdeveloped in a number of regards. In addition, we clarify the interplay between sophistication about symmetries, and a separate debate to which Dewar has contributed—viz., that between interpretational versus motivational approaches to symmetry transformations.

It is striking to note that the political unrest and instability in 1981 coincided with continual and serious unrest on the national money market. On the political party level, one notes that the Christian Democratic Parties and the Socialist Parties had more and more difficulties in getting along with each other. This probably is related to the policyof the new chairman of the French-speaking Socialist Party, who has resolutely chosen to back Wallonia. The Flemish Christian Democratic Party, has still difficulties (...) in seeing itself as the largest party in Flanders and to act appropriately. In addition, the French-speaking Socialist Party feels confident in the conviction that influential circles, including the Court, prefer not to see the Socialists in the opposition. This has motivated some to cling as long as possible to the formation of a three -party cabinet. The actual political situation, however, has clearly demonstrated that such a three-party cabine! cannot fu nction for a long time. The question remains why the Christian Democratic Party has not pursued elections with the same energy as it did in September af ter the resignationof the Martens IV government. In the meantime, it has become evident that the state reform of August 1980 is certainly not «completed», that is should best be redone, andthat the consequences of this reorganization can be gauged only with difficulty.

The year 1980 might become a basic reference year for the study of «political stability» and «governmental maintenance» in Belgium.Indeed, within this year, four different cabinet formulae have been used. The first cabinet included the two christian-democratic parties, the two socialist parties and the Brussels regionalist party. When the latter was fired, the combination of the remaining did not last long, for the cabinet fell in parliament - rare exception in Belgium -, by not obtaining a 2/3 majority. Therefore, a (...) cabinet of the traditional parties had to be formed to pass the devolution bill. Within a short time, this third coalition broke down on proposals on cuts in the budgets. A new negociation between socialists and christian-democrats led to the fourth Martens' cabinet. Although the Belgian classe politica favoured a cabinet that would last an entire legislature, all these coalitions arosefrom only one general election. (shrink)

A report on the 2019 Bonn “Simplicities and Complexities” Conference, organized by "The Epistemology of the Large Hadron Collider" research unit.

The paper presents a renewed Habermasian view on transnational multi-stakeholder initiatives and assesses the institutional characteristics of the Equator Principles Association from a deliberative democracy perspective. Habermas’ work has been widely adopted in the academic literature on the political responsibilities of corporations, and also in assessing the democratic qualities of MSIs. Commentators, however, have noted that Habermas’ approach relies very much on ‘nation-state democracy’ and may not be applicable to democracy in MSIs—in which nation-states are virtually absent. We argue that (...) Habermas’ detailed conceptualization of the institutionalization of deliberative democracy can be applied to transnational MSIs if these initiatives can be said to have their own ‘dèmoi’ that can be represented in associational decision-making. Therefore, we develop a definition of the dèmos of an MSI based on the notion of collective agency. Subsequently, we explain how Habermas’ approach to democracy can be applied to MSIs and show that it has more to offer than hitherto has been uncovered. Our illustrative analysis of the EPA confirms the criticisms regarding this MSI which have recently been articulated by researchers and practitioners, but also yields new findings and possible avenues for the further development of the EPA: That is, although our assessment suggests that the EPA in its current state is still far from being a democratic MSI, the possibility of a sensible analysis of its democratic character indicates that transnational MSIs can, in principle, help to fill governance gaps in a democratic way.

This paper scrutinises the tenability of a strict conceptual distinction between space and matter via the lens of the debate between modified gravity and dark matter. In particular, we consider Berezhiani and Khoury's novel 'superfluid dark matter theory' as a case study. Two families of criteria for being matter and being spacetime, respectively, are extracted from the literature. Evaluation of the new scalar field postulated by SFDM according to these criteria reveals that it is as much matter as anything could (...) possibly be, but alsoꟷbelow the critical temperature for superfluidityꟷas much spacetime as anything could possibly be. A sequel paper examines possible interpretations of SFDM in light of this result, as well as the consequences for our understanding of the modified gravity/ dark matter distinction and the broader spacetime–matter distinction.

One important concern regarding implantable Brain Computer Interfaces is the fear that the intervention will negatively change a patient’s sense of identity or agency. In particular, there is concern that the user will be psychologically worse-off following treatment despite postoperative functional improvements. Clinical observations from similar implantable brain technologies, such as deep brain stimulation, show a small but significant proportion of patients report feelings of strangeness or difficulty adjusting to a new concept of themselves characterized by a maladaptive je ne (...) sais quoi despite clear motor improvement. Despite the growing number of cases in the DBS literature, there is currently no accepted or standardized tool in neuroethics specifically designed to capture the phenomenological postoperative experience of patients implanted with DBS or BCI devices. Given potential risks of postoperative maladaptation, it is important for the field of neuroethics to develop a qualitative instrument that can serve as a shared method for capturing postoperative variations in patient experience of identity and agency. The goal of this article is to introduce an instrument we have developed for this purpose and call for further neuroethical efforts to assess the phenomenology of implantable brain device use.

How could the paradigm shift towards enactive embodied cognitive science have implications for society and politics? Translating insights form enactive embodied cognitive science into ways of dealing with real-life issues is an important challenge. This paper focuses of the urgent societal issue of social cohesion, which is crucial in our increasingly segregated and polarized Western societies. We use Rietveld’s philosophical Skilled Intentionality Framework and work by the multidisciplinary studio RAAAF to extend Lambros Malafouris’ Material Engagement Theory to the social domain. (...) How could a landscape of social affordances generate change in the behavioral patterns of people from different socio-cultural backgrounds? RAAAF is currently imagining and planning an ambitious intervention in the public domain that could really change existing socio-cultural practices and aims to contribute to social cohesion. An animation film it made introduces a landscape of social affordances. We will present and discuss this Trusted Strangers animation film, which is a thinking model for new public domain all over the world. Tha animation film visualizes how a well-designed landscape of social affordances could invite all sorts of interactions between people from different socio-cultural backgrounds. (shrink)

Astroturf organizations are fake grassroots organizations usually sponsored by large corporations to support any arguments or claims in their favor, or to challenge and deny those against them. They constitute the corporate version of grassroots social movements. Serious ethical and societal concerns underline this astroturfing practice, especially if corporations are successful in influencing public opinion by undertaking a social movement approach. This study is motivated by this particular issue and examines the effectiveness of astroturf organizations in the global warming context, (...) wherein large corporate polluters have an incentive to set up astroturf organizations to undermine the importance of human activities in climate change. We conduct an experiment to determine whether astroturf organizations have an impact on the level of user certainty about the causes of global warming. Results show that people who used astroturf websites became more uncertain about the causes of global warming and humans’ role in the phenomenon than people who used grassroots websites. Astroturf organizations are hence successful in promoting business interests over environmental protection. In addition to the multiple business ethics issues it raises, astroturfing poses a significant threat to the legitimacy of the grassroots movement. (shrink)

In the North American context, one trend in introductory Protestant Christian ethics texts is clear: the desire to draw the focus away from moral pronouncements about contemporary ‘issues’ in order to concentrate on what it means to be truly human, that is, to see the world as followers of Christ made in the image of God and to employ forms of moral reasoning appropriate to this vision. The article illuminates the particular emphases displayed in contemporary Protestant ethics texts published in (...) the United States over the past decade as each contributes to this agenda of renewal. In conclusion, I argue that the trend toward eschewing ‘applied’ ends is laudable and yet ambiguous. I suggest this trend may also be tied to the relative gender and racial uniformity of the authors, because what is frequently absent in this collection are the social and political concerns commonly voiced by more marginalized voices.

Absolutism about mass claims that mass ratios obtain in virtue of absolute masses. Comparativism denies this. Dasgupta, Oxford studies in metaphysics, Oxford University Press, Oxford, 2013) argues for comparativism about mass, in the context of Newtonian Gravity. Such an argument requires proving that comparativism is empirically adequate. Dasgupta equates this to showing that absolute masses are undetectable, and attempts to do so. This paper develops an argument by Baker to the contrary: absolute masses are in fact empirically meaningful, that is (...) detectable. Additionally, it is argued that the requirement of empirical adequacy should not be cashed out in terms of undetectability in the first place. The paper closes by sketching the possible strategies that remain for the comparativist. Along the way a framework is developed that is useful for thinking about these issues: Ozma games—how could one explain to an alien civilisation what an absolute mass is? (shrink)

In the debate about the nature of social cognition we see a shift towards theories that explain social understanding through interaction. This paper discusses autopoietic enactivism and the we-mode approach in the light of such developments. We argue that a problem seems to arise for these theories: an interactionist account of social cognition makes the capacity of shared intentionality a presupposition of social understanding, while the capacity of engaging in scenes of shared intentionality in turn presupposes exactly the kind of (...) social understanding that it is intended to explain. The social capacity in question that is presupposed by these accounts is then analyzed in the second section via a discussion and further development of Searle’s ‘sense of us’ and ‘sense of the other’ as a precondition for social cognition and joint action. After a critical discussion of Schmid’s recent proposal to analyze this in terms of plural pre-reflective selfawareness, we develop an alternative account. Starting from the idea that infants distinguish in perception between physical objects and other agents we distinguish between affordances and social affordances and cash out the notion of a social affordance in terms of “interaction-oriented representations”, parallel to the analysis of object affordances in terms of “action-oriented representations”. By characterizing their respective features we demonstrate how this approach can solve the problem formulated in the first part. (shrink)

“Shooting [or ‘guessing’] characters” was a game, and later a communication method, based on phonological analysis of Chinese syllables. Over time, it became used in a variety of ways, including as a teaching tool, a cipher, and a phonological writing aid for the less educated. The actual and proposed applications of one phonological game show that Chinese phonology did not just exist in books, but encompassed distinct non-written practices that were essential to its proliferation. Chinese phonology is generally studied as (...) a source for the history of the Chinese language, but it is also of interest for the history of cultural and intellectual life. (shrink)

The debate concerning the ontological status of spacetime is standardly construed as a dilemma between substantivalism and relationalism. I argue that a trilemma is more appropriate, emergent spacetime theories being the third category. Traditional philosophical arguments do not distinguish between emergent spacetime and substantivalism. It is arguments from physics that suggest giving up substantivalism in favour of emergent spacetime theories. The remaining new dilemma is between emergent spacetime and relationalism. I provide a list of questions, which one should consider when (...) discussing emergent spacetime theories, and apply them to a quantum superfluid toy model of emergent spacetime. (shrink)

This thesis concerns the metaphysics of scale. It investigates the implications of a physical determinable being dimensionful. In particular, it considers the case study of mass, as it features within Newtonian Gravity. Nevertheless, most of the terminology, methodology and arguments developed should be relatively straightforwardly applicable to other determinables and theories. -/- Weak Absolutism about mass holds that mass ratios obtain in virtue of absolute masses. Weak Comparativism denies this. In the first five chapters I argue in favour of Weak (...) Absolutism over Weak Comparativism. The sixth chapter argues against reducing mass to other non-mass facts. The overall conclusion is Strong Absolutism about mass within Newtonian Gravity: mass ratios obtain in virtue of absolute masses, which themselves are fundamental (i.e. they do not require anything further in order to obtain). -/- Comparativism promises to recover all the virtues of absolutism, in particular its empirical adequacy, but at a lower 'metaphysical cost'. Special attention is given to Dasgupta's recent comparativist proposal. Dasgupta interprets the requirement of empirical adequacy in terms of the undetectability of the absolute mass scale. I argue that undetectability is an unsuitable way of understanding empirical adequacy and that we would do better to understand it in terms of a theory's ability to correctly generate the set of empirically possible worlds (or at least the actual world). I refute Dasgupta's comparativism both on my terms and on his own terms. I subsequently develop and strongly criticise alternative versions of comparativism. Chapter five sheds doubt on the supposed 'metaphysical parsimony' of comparativism. -/- This debate should be of particular interest to readers who engage with the substantivalism-relationalism debate. These debates are much more entwined than previously acknowledged, which provides a significant source of mutual inspiration, although I do also draw out some important disanalogies. -/- . (shrink)

Absolutism about mass within Newtonian gravity claims that mass ratios obtain in virtue of absolute masses. Comparativism denies this. Defenders of comparativism promise to recover all the empirical and theoretical virtues of absolutism, but at a lower ‘metaphysical cost’. This article develops a Machian form of comparativism about mass in Newtonian gravity, obtained by replacing Newton’s constant in the law of universal gravitation by another constant divided by the sum over all masses. Although this form of comparativism is indeed empirically (...) equivalent to the absolutist version of Newtonian gravity—thereby meeting the challenge posed by the comparativist’s bucket argument—it is argued that the explanatory power and metaphysical parsimony of comparativism are highly questionable.

Comparativism—the view that mass ratios are not grounded in absolute masses—faces a challenge by Baker which suggests that absolute masses are empirically meaningful. Regularity comparativism uses a liberalized version of the Mill-Ramsey-Lewis Best Systems Account to have both the laws of Newtonian gravity and the absolute mass scale supervene on a comparativist Humean mosaic as a package deal. I discuss three objections to this view and conclude that it is untenable. The most severe problem is that once we have reduced (...) away the absolute masses, there is nothing that stops us from also reducing the mass ratios. (shrink)
