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.

Dimensional quantities such as length, mass and charge, i.e., numbers combined with a conventional unit, are essential components of theories in the sciences, especially physics, chemistry and biology. Do they represent a world with absolute physical magnitudes, or are they merely magnitude ratios in disguise? Would we notice a difference if all the distances or charges in the world suddenly doubled? These central questions of this Element are illustrated by imagining how one would convey the meaning of a kilogram to (...) aliens if one were only allowed to communicate via Morse code. (shrink)

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.

Recently, there has been increasing interest in the use of heavily restricted randomization designs which enforce balance on observed covariates in randomized controlled trials. However, when restrictions are strict, there is a risk that the treatment effect estimator will have a very high mean squared error. In this article, we formalize this risk and propose a novel combinatoric-based approach to describe and address this issue. First, we validate our new approach by re-proving some known properties of complete randomization and restricted (...) randomization. Second, we propose a novel diagnostic measure for restricted designs that only use the information embedded in the combinatorics of the design. Third, we show that the variance of the MSE of the difference-in-means estimator in a randomized experiment is a linear function of this diagnostic measure. Finally, we identify situations in which restricted designs can lead to an increased risk of getting a high MSE and discuss how our diagnostic measure can be used to detect such designs. Our results have implications for any restricted randomization design and can be used to evaluate the trade-off between enforcing balance on observed covariates and avoiding too restrictive designs.

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.

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)

In mirror mark tests dolphins twist, posture, and engage in open-mouth and head movements, often repetitive. Because postures and an open mouth are also dolphin social behaviours, we used self-view television as a manipulatable mirror to distinguish between self-examination and social behavior. Two dolphins were exposed to alternating real-time self-view and playback of the same to determine if they distinguished between them. The adult male engaged in elaborate open-mouth behaviors in mirror mode, but usually just watched when playing back the (...) same material. Mirror mode behavior was also compared to interacting with real dolphins . Mark tests were conducted, as well as switches from front to side self-views to see if the dolphins turned. They presented marked areas to self-views to see if the dolphins turned. They presented marked areas to the self-view television and turned. The results suggest self-examination over social behavior.

In diesem biografisch gesättigten Essay entfaltet der Philosoph Rainer Marten vor dem Hintergrund des neoliberalen Zeitgeists der Silicon Valley-Gegenwart die Essenz seines Denkens in kraftvollen Zügen. Im Angesicht des eigenen Lebensendes legt er an unsere Zeit den Maßstab überzeitlicher Lehren der Philosophie, Theologie und Lebenskunst. Mit wachem Blick für die Verwerfungen unserer Zeit tritt er ein für die Schönheit des fragilen Lebens, dessen Grund er in der Poesie der Notwendigkeit sieht. Im Nachdenken über Technomessianismus, Verführung des Bösen und Künstliche Intelligenz (...) stärkt er sein Konzept des Humanums, plädiert für das Leben als Kunstwerk und gegen dessen Instrumentalisierung.

This paper pushes back against the Democritean-Newtonian tradition of assuming a strict conceptual dichotomy between spacetime and matter. Our approach proceeds via the more narrow distinction between modified gravity/spacetime and dark matter. A prequel paper argued that the novel field Φ postulated by Berezhiani and Khoury's 'superfluid dark matter theory' is as much matter as anything could possibly be, but also below the critical temperature for superfluidity as much spacetime as anything could possibly be. Here we introduce and critically evaluate (...) three groups of interpretations that one should consider for such Janus-faced theories. The consubstantiality interpretation holds that Φ is both matter and a modification of spacetime, analogously to the sense in which Jesus is both human and god. The fundamendalist interpretations consider for each of these roles whether they are instantiated fundamentally or emergently. The breakdown interpretations focus on the question of whether Φ signals the breakdown, in some sense to be specified, of the MG-DM dichotomy and perhaps even the broader spacetime–matter distinction. More generally, it is argued that hybrid theories urge a move towards a single space of theories, rather than two separate spaces of spacetime theories and matter theories, respectively. (shrink)

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.

It has been claimed that a sense of us is presupposed for shared intentions to be possible. Searle introduced this notion together with the notion of the sense of the other. in joint action. It argues that the sense of the other is a necessary condition for a sense of us. Whereas thisarticle distinguishes between the “sense of the other” and the “sense of us” and elaborates on their role the sense of the other is immediate and automatic, the sense (...) of us can (but need not) arise between people and can (a) develop over time, (b) depend on the situation, and (c) involves several sufficient but not necessary processes. The article relies on research on core knowledge to better understand the sense of the other. It elaborates the sense of us using insights from cognitive science and social psychology. The article shows that the sense of the other and the sense of us can contribute to our understanding of the perception of possibilities for joint action and how individuals can come to experience actions and intentions as shared, even if the participants lack common knowledge. This leads to the conclusion that people are ordinarily socially oriented rather than individually. (shrink)

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)

The paper presents a renewed Habermasian view on transnational multi-stakeholder initiatives (MSIs) and assesses the institutional characteristics of the Equator Principles Association (EPA) from a deliberative democracy perspective. Habermas’ work has been widely adopted in the academic literature on the political responsibilities of (multinational) corporations (i.e., political corporate social responsibility), 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.

Among the many common criticisms of the Turing test, a valid criticism concerns its scope. Intelligence is a complex and multi-dimensional phenomenon that will require testing using as many different formats as possible. The Turing test continues to be valuable as a source of evidence to support the inductive inference that a machine possesses a certain kind of intelligence and when interpreted as providing a behavioural test for a certain kind of intelligence. This paper raises the novel criticism that the (...) Turing test represents an example of Goodhart’s Law operating in the field of artificial intelligence. As one measure towards the goal of creating genuinely intelligent machines, the Turing test must not be confused with the goal itself. Moreover, the Turing test ought to be augmented such that through its use additional evidence could be secured to support the strong inference that a machine, were it to pass the Turing Test, could think like a human.

It is argued that Newtonian mass cannot be reduced to kinematical quantities---distance, velocity and acceleration---without losing the explanatory and predictive power of Newtonian Gravity.

This sophisticated, difficult, and puzzling book consolidates and continues the exploration of our finitude pursued in Adrian Moore’s earlier book The Infinite and in a number of previous and intervening articles by him. One of Moore’s purposes in Points of View is to defend an affirmative answer to the question “Are absolute representations possible?” Moore takes this question to be an expression of an essential connection between current concerns about language and mind, and what he regards as deeper perennial concerns (...) about our finitude. Another of his purposes is to recommend acquisition of a certain taste for nonsense as an apt response to those connected concerns, as “a philosophical tactic of very general utility.”. (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)

According to the standard model of cosmology, Λ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Lambda$$\end{document}CDM, the mass-energy budget of the current stage of the universe is not dominated by the luminous matter that we are familiar with, but instead by some form of dark matter (and dark energy). It is thus tempting to adopt scientific realism about dark matter. However, there are barely any constraints on the myriad of possible properties of this entity—it is not even certain (...) that it is a form of matter. In light of this underdetermination I advocate caution: we should not (yet) be dark matter realists. The “not(-yet)-realism” that I have in mind is different from Hacking’s (Philos Sci 56 (4), 555–581, 1989) anti-realism, in that it is semantic rather than epistemological. It also differs from the semantic anti-realism of logical empiricism, in that it is naturalistic, such that it may only be temporary and does not automatically apply to all other unobservables (or even just to all other astronomical unobservables, as with Hacking’s anti-realism). The argument is illustrated with the analogy of the much longer history of the concept of a gene, as the current state of the concept of dark matter resembles in some relevant ways that of the early concept of genes.

Laplace wondered about the minimal choice of initial variables and parameters corresponding to a well-posed initial value problem. Discussions of Laplace’s problem in the literature have focused on choosing between spatiotemporal variables relative to absolute space or merely relative to other material bodies and between absolute masses or merely mass ratios. This paper extends these discussions of Laplace’s problem, in the context of Newtonian Gravity, by asking whether mass needs to be included in the initial state at all, or whether (...) a purely spatiotemporal initial state suffices. It is argued that mass indeed needs to be included; removing mass from the initial state drastically reduces the predictive and explanatory power of Newtonian Gravity. (shrink)

Artificially intelligent machines are different in kind from all previous machines and tools. While many are used for relatively benign purposes, the types of artificially intelligent machines that we should care about, the ones that are worth focusing on, are the machines that purport to replace humans entirely and thereby engage in what Brian Cantwell Smith calls “judgment.” As impressive as artificially intelligent machines are, their abilities are still derived from humans and as such lack the sort of normative commitments (...) that humans have. So while artificially intelligent machines possess a great capacity for “reckoning,” to use Smith’s terminology, i.e., a calculative prowess of extraordinary utility and importance, they still lack the kind of considered human judgment that accompanies the ethical commitment and responsible action we humans must ultimately aspire toward. But there is a perfect technological storm brewing. Artificially intelligent machines are analogous to a perfect storm in that such machines involve the convergence of a number of factors that threaten our ability to behave ethically and maintain meaningful human control over the outcomes of processes involving artificial intelligence. I argue that the storm in the context of artificially intelligent machines makes us vulnerable to moral complacency. That is, this perfect technological storm is capable of lulling people into a state in which they abdicate responsibility for decision-making and behaviour precipitated by the use of artificially intelligent machines, a state that I am calling “moral complacency.” I focus on three salient problems that converge to make us especially vulnerable to becoming morally complacent and losing meaningful human control. The first problem is that of transparency/opacity. The second problem is that of overtrust in machines, often referred to as the automation bias. The third problem is that of ascribing responsibility. I examine each of these problems and how together they threaten to render us morally complacent. (shrink)

Two approaches have emerged to resolve discrepancies between predictions and observations at galactic and cosmological scales: introducing dark matter or modifying the laws of gravity. Practitioners of each approach claim to better satisfy a different explanatory ideal, either unification or simplicity. In this chapter, we take a closer look at the ideals and at the successes of these approaches in achieving them. Not only are these ideals less divisive than assumed, but moreover we argue that the approaches are focusing on (...) different aspects of the same ideal. This realisation opens up the possibility of a more fruitful trading zone between dark matter and modified gravity communities. (shrink)

The present paper summarizes the development of the national electronic Identity Management System (eIDMS) in Estonia according to a conceptual framework developed in an European comparative research project outlined in the first chapter of this special issue. Its main function is to amend the picture of the European eIDMS landscape by presenting a case with high involvement of the private sector and thereby checking the generalizations from the comparisons of Austria, Belgium, Germany and Spain, presented by Kubicek and Noack in (...) the previous chapter of this special issue. Starting with a short introduction into the historical background of identity documents in Estonia the national population register, the passport as well as the bank ID are described as the main pillars of the Estonian eIDMS, on which the national ID card builds on, which has been introduced in 2002. The technical features of the eID and the ID card are described in Section two as well as the areas of application and the processes for production and distribution. Section three presents the actors constellation, Section four the time line of the development process, starting from 1997. Section five deals with the diffusion and promotion of the ID card and the eID authentication function. After a very low and slow take up during the first 5 years due to a cooperation agreement between major banks, telecom operators and the government usage has increased. But still the authentication by Internet banks, which provides authentication services to third parties, including government, is the biggest competitor for the eID function on the national eID card. Only recently the major banks have announced to slowly fade out the password cards and PIN calculators as alternative modes of bank authentication. (shrink)

In everyday contexts we do numerous things together. Philosophers of collective intentionality have wondered how we can distinguish parallel cases from cases where we act together. Often their theories argue in favor of one characteristic, feature, or function, that differentiates the two. This feature then distinguishes parallel actions from joint action. The approach in this book is different. Three claims are developed: (1) There are several functions that help human agents coordinate and act together. (2) This entails that joint action (...) should be understood through these different, interrelated, types of coordination. (3) A multidimensional conceptual space, with three levels of control and coordination, will allow us to connect these different forms of coordination and their interdependencies. This allows us to understand the jointness of an action in a more differentiated and encompassing way. This approach has ramifications for several distinctions that are typically understood to be binary, including those between action and mere bodily movement, joint action and parallel action, and action together and not together.

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)

The problem of joint measurement of incompatible observables is investigated. Measurements are represented by positive operator-valued measures. A quantitative notion of inaccuracy is defined. It is shown that within this framework joint inaccurate measurements are possible for arbitrary maximal projection-valued measures on finite-dimensional spaces. The accuracy of such measurements is limited, as is shown by an inaccuracy inequality we derive. This new type of uncertainty relation can be unambiguously interpreted as referring to measurement precision rather than preparative quality. Several recent (...) experiments are seen to be realizations of such joint measurements. (shrink)
