This survey covers some of the main philosophical debates raised by the framework of effective field theories during the last decades. It is centered on three issues: whether effective field theories underpin a specific realist picture of the world, whether they support an anti-reductionist picture of physics, and whether they provide reasons to give up the ultimate aspiration of formulating a final and complete physical theory. Reviewing the past and current literature, we argue that effective field theories do not give (...) convincing reasons to adopt a particular stance towards these speculative issues. They hold good prospects for asking ontologically perspicuous and sensible questions about currently accessible domains. With respect to more fundamental questions, however, the only certainty is provisional and instrumental: effective theories are currently indispensable for conducting fruitful scientific research.

What belongs to quantum theory is no more than what is needed for its derivation. Keeping to this maxim, we record a paradigmatic shift in the foundations of quantum mechanics, where the focus has recently moved from interpreting to reconstructing quantum theory. Several historic and contemporary reconstructions are analyzed, including the work of Hardy, Rovelli, and Clifton, Bub and Halvorson. We conclude by discussing the importance of a novel concept of intentionally incomplete reconstruction.
Fine-tuning arguments are a frequent find in the literature on quantum field theory. They are based on naturalness—an aesthetic criterion that was given a precise definition in the debates on the Higgs mechanism. We follow the history of such definitions and of their application at the scale of electroweak symmetry breaking. They give rise to a special interpretation of probability, which we call Gedankenfrequency. Finally, we show that the argument from naturalness has been extended to comparing different models of the (...) physics beyond the Standard Model and that naturalness in this case can at best be understood a socio-historic heuristic.

This article summarizes the recommendations concerning robotics as issued by the Commission for the Ethics of Research in Information Sciences and Technologies (CERNA), the French advisory commission for the ethics of information and communication technology (ICT) research. Robotics has numerous applications in which its role can be overwhelming and may lead to unexpected consequences. In this rapidly evolving technological environment, CERNA does not set novel ethical standards but seeks to make ethical deliberation inseparable from scientific activity. Additionally, it provides tools (...) and guidance for researchers and research institutions. (shrink)
To believe that every single scientist ought to be individually engaged in ethical thinking in order for science to be responsible at a collective level may be too demanding, if not plainly unrealistic. In fact, ethical labor is typically distributed across different kinds of scientists within the scientific community. Based on the empirical data collected within the Horizon 2020 ‘RRI-Practice’ project, we propose a classification of the members of the scientific community depending on their engagement in this collective activity. Our (...) classification offers, on the one hand, a model of how the ethical aspects of science are taken into consideration by scientists and, on the other, some indications on how to institutionalize ethics in science.

If physics is a science that unveils the fundamental laws of nature, then the appearance of mathematical concepts in its language can be surprising or even mysterious. This was Eugene Wigner’s argument in 1960. I show that another approach to physical theory accommodates mathematics in a perfectly reasonable way. To explore unknown processes or phenomena, one builds a theory from fundamental principles, employing them as constraints within a general mathematical framework. The rise of such theories of the unknown, which I (...) call blackbox models, drives home the unsurprising effectiveness of mathematics. I illustrate it on the examples of Einstein’s principle theories, the S-matrix approach in quantum field theory, effective field theories, and device-independent approaches in quantum information.

If the technological situation is unique, the ways to understand the contemporary moral condition are not. We link it to age-old questions: in fact, the power promised by technol-ogy only establishes a new form of human finitude. In the face of this continuity of the fundamental moral condition, we examine a number of alternative ways of thinking about the basis of responsible innovation, exploring the metaphors of quasi-parental and political responsibilities, as well as the place of virtue in innovation and (...) the role of cul-tural narratives in helping us understand the limits of responsible innovation.

A paradigmatic shift in the foundations of quantum mechanics is recorded, from interpreting to reconstructing quantum theory. Examples of reconstruction are analyzed, and conceptual foundations of the information-theoretic reconstruction developed. A concept of intentionally incomplete reconstruction is introduced to mark the novel content of research in the foundation of quantum theory. ‡Many thanks to Lucien Hardy, Jeff Bub and Bill Demopoulos for their comments.

We give reasons for the importance of old narratives, including myths, in ethical thinking about science and technology. On the example of a legend about creating artificial men we explore the side effects of having too much success and the problem of intermediate social status of bioengineered artefacts.

Due primarily to technological advances over the last decade, quantum research has become a key priority area for science and technology policy all over the world. With this manifesto, we wish to prevent quantum technology from running into fiascos of implementation at the interface of science and society. To this end, we identify key stumbling blocks and propose recommendations.
Quantum technologies can be presented to the public with or without introducing a strange trait of quantum theory responsible for their non-classical efficiency. Traditionally the message was centered on the superposition principle, while entanglement and properties such as contextuality have been gaining ground recently. A less theoretical approach is focused on simple protocols that enable technological applications. It results in a pragmatic narrative built with the help of the resource paradigm and principle-based reconstructions. I discuss the advantages and weaknesses of (...) these methods. To illustrate the importance of new metaphors beyond the Schrödinger cat, I briefly describe a non-mathematical narrative about entanglement that conveys an idea of some of its unusual properties. If quantum technologists are to succeed in building trust in their work, they ought to provoke an aesthetic perception in the public commensurable with the mathematical beauty of quantum theory experienced by the physicist. The power of the narrative method lies in its capacity to do so. (shrink)
Some mathematical theories in physics justify their explanatory superiority over earlier formalisms by the clarity of their postulates. In particular, axiomatic reconstructions drive home the importance of the composition rule and the continuity assumption as two pillars of quantum theory. Our approach sits on these pillars and combines new mathematics with a testable prediction. If the observer is defined by a limit on string complexity, information dynamics leads to an emergent continuous model in the critical regime. Restricting it to a (...) family of binary codes describing ‘bipartite systems,’ we find strong evidence of an upper bound on bipartite correlations equal to 2.82537. This is measurably different from the Tsirelson bound. The Hilbert space formalism emerges from this mathematical investigation as an effective description of a fundamental discrete theory in the critical regime. (shrink)
We start by remarks on the scientific and societal context of today's theoretical physics. Major classes of models for physics to be explored at the LHC are then reviewed. This leads us to propose an LHC timeline and a list of potential effects on theoretical physics and the society. We then explore three conceptual questions connected with the LHC physics: symmetry (and symmetry breaking), effective field theory, and fine tuning.
RRI is a science policy framework in the Horizon-2020 programme of the European Commission. The funding programme was launched in 2014, while the conceptual foundations of RRI have been laid in a series of conferences, expert meetings and publications beginning around 2011. RRI seeks to engage publics with science and technology stakeholders in a responsible, multi-dimensional dialogue on five themes called »RRI keys«: ethics, science education, open access, gender equality, and societal engagement.
This article is concerned with predictions of future events, such as technological achievements and changes in the human condition that they will bring about. Cognitive barriers arise when human agents are either asked or forced to make judgments and decisions with respect to unknown singular events. This article argues that barriers such as an aversion to not knowing and the impossibility to believe trump expert and ordinary human reasoning. These barriers apply to nanotechnology. To avoid undesired societal effects arising from (...) them, this essay proposes a set of steps designed to foster responsible public dialogue. (shrink)
Modern microscopes create a capacity to see and act at the scale where unassisted human senses are powerless. Images of nanoscale phenomena represent a world that effectively intervenes in human life while remaining distant and ineffable. This combination of an unbridgeable distance between man and technology with a real power of the latter over the human condition is characteristic, not only of nanotechnology, but also of the theology of sacred icons that mediate in the knowledge of divine reality. We draw (...) an anthropological analogy between nanotechnological images and sacred icons, and we employ it to analyze the functioning of such images in society. The questions that we study include: a) the art of mediation in representing the ineffable and its necessity; b) the effects provoked by such images; c) primitive comprehension of nanoscale images. This work has repercussions for a wide variety of disciplinary accounts and practices, from the anthropologist and the philosopher to the laboratory scientist, the art critic, and the engineer who conceives and designs nanoscale instruments.

A number of recent reports and overviews on the ethical and societal problems of nanotechnology present a public that is polarized about nanotechnology. Very little responsible analysis can be found between those poles for two reasons. First, the debate about the highly controversial notion of molecular manufacturing introduced by Eric Drexler shaped much of the early discussion. Second, the polarization can be seen as a consequence of uncertainty about nanotechnology compounded by cognitive barriers. A reporter to UNESCO acknowledges that “…Assessments (...) of nanotechnology tend to radically diverge…These radically diverging assessments that have thus far dominated the debate on nanotechnology seem to be due to a lack of common ground.” The “lack of common ground” is not unprecedented in the history of technology, and scientists rightfully fear a new “GMO debacle.”.
