Local gauge theories are in a complicated relationship with boundaries. Whereas fixing the gauge can often shave off unwanted redundancies, the coupling of different bounded regions requires the use of gauge-variant elements. Therefore, coupling is inimical to gauge-fixing, as usually understood. This resistance to gauge-fixing has led some to declare the coupling of subsystems to be the \textit{raison d'\^etre} of gauge \cite{RovelliGauge2013}. Indeed, while gauge-fixing is entirely unproblematic for a single region without boundary, it introduces arbitrary boundary conditions on the (...) gauge degrees of freedom themselves---these conditions lack a physical interpretation when they are not functionals of the original fields. Such arbitrary boundary choices creep into the calculation of charges through Noether's second theorem, muddling the assignment of physical charges to local gauge symmetries. The confusion brewn by gauge at boundaries is well-known, and must be contended with both conceptually and technically. It may seem natural to replace the arbitrary boundary choice with new degrees of freedom, for using such a device we resolve some of these confusions while leaving no gauge-dependence on the computation of Noether charges \cite{DonnellyFreidel}. But, concretely, such boundary degrees of freedom are rather arbitrary---they have no relation to the original field-content of the field theory. How should we conceive of them? Here I will explicate the problems mentioned above and illustrate a possible resolution: in a recent series of papers \cite{GomesRiello2016, GomesRiello2018, GomesHopfRiello} the notion of a connection-form was put forward and implemented in the field-space of gauge theories. Using this tool, a modified version of symplectic geometry---here called `horizontal'---is possible. Independently of boundary conditions, this formalism bestows to each region a physically salient, relational notion of charge: the horizontal Noether charge. Meanwhile, as required, the connection-form mediates an irenic composition of regions, one compatible with the attribution of horizontal Noether charges to each region. Thes aims of this paper are to highlight the boundary issues in the treatment of gauge, and to discuss how gauge theory may be conceptually clarified in light of a resolution to these issues.

We review three broadly geometrodynamical---and in part, Machian or relational---projects, from the perspective of spacetime functionalism. We show how all three are examples of functionalist reduction of the type that was advocated by D. Lewis, and nowadays goes by the label `the Canberra Plan’. The projects are: the recovery of geometrodynamics by Hojman et al. ; the programme of Schuller and collaborators to deduce a metric from the physics of matter fields; the deduction of the ADM Hamiltonian by Gomes and (...) Shyam. We end by drawing a positive corollary about shape dynamics: namely, it has a good rationale for the Hamiltonian it postulates. (shrink)

Not all symmetries are on a par. For instance, within Newtonian mechanics, we seem to have a good grasp on the empirical significance of boosts, by applying it to subsystems. This is exemplified by the thought experiment known as Galileo’s ship: the inertial state of motion of a ship is immaterial to how events unfold in the cabin, but is registered in the values of relational quantities such as the distance and velocity of the ship relative to the shore. But (...) the significance of gauge symmetries seems less clear. For example, can gauge transformations in Yang-Mills theory—taken as mere descriptive redundancy—exhibit a similar relational empirical significance as the boosts of Galileo’s ship? This question has been debated in the last fifteen years in philosophy of physics. I will argue that the answer is ‘yes’, but only for a finite subset of gauge transformations, and under special conditions. Under those conditions, we can mathematically identify empirical significance with a failure of supervenience: the state of the Universe is not uniquely determined by the intrinsic state of its isolated subsystems. Empirical significance is therefore encoded in those relations between subsystems that stand apart from their intrinsic states. (shrink)

_Changing the Subject_ is a classic critique of traditional psychology in which the foundations of critical and feminist psychology are laid down. Pioneering and foundational, it is still _the _groundbreaking text crucial to furthering the new psychology in both teaching and research. Now reissued with a new foreword describing the changes which have taken place over the last few years, _Changing the Subject _will continue to have a significant impact on thinking about psychology and social theory.

‘Social auditing’ is everywhere. An increasing number of companies – and also public and voluntary sector organisations – are trying to assess their social performance systematically. Shell, BP and General Motors are among them. How are they doing it? What impact do NGOs and civil society organisations have on this process? Do they have a privileged place in social audits? This article looks at these questions, and sets out a framework for understanding social audits and civil society. Examples are drawn (...) particularly from the recent Camelot social audit . Camelot plc is the operator of the UK national lottery. (shrink)

The inherent difficulty in talking about quantum decoherence in the context of quantum cosmology is that decoherence requires subsystems, and cosmology is the study of the whole Universe. Consistent histories gave a possible answer to this conundrum, by phrasing decoherence as loss of interference between alternative histories of closed systems. When one can apply Boolean logic to a set of histories, it is deemed ‘consistent’. However, the vast majority of the sets of histories that are merely consistent are blatantly nonclassical (...) in other respects, and further constraints than just consistency need to be invoked. In this paper, I attempt to give an alternative answer to the issues faced by consistent histories, by exploring a timeless interpretation of quantum mechanics of closed systems. This is done solely in terms of path integrals in non-relativistic, timeless, configuration space. What prompts a fresh look at such foundational problems in this context is the advent of multiple gravitational models in which Lorentz symmetry is not fundamental, but only emergent. And what allows this approach to overcome previous barriers to a timeless, conditional probabilities interpretation of quantum mechanics is the new notion of records—made possible by an inherent asymmetry of configuration space. I outline and explore consequences of this approach for foundational issues of quantum mechanics, such as the natural emergence of the Born rule, conservation of probabilities, and the Sleeping Beauty paradox.

Through a theoretical examination of the preventive turn in criminal law and justice which has gained momentum in Anglo-American criminal justice systems since the late-twentieth century, The Preventive Turn in Criminal Law demonstrates how recent transformations in criminal law and justiceare intrinsically related to and embedded in the way liberal society and liberal law have been imagined, developed, and conditioned by its social, political, and historical context. Henrique Carvalho identifies a tension between the idea of punishment as an expression of (...) individual justice, andprevention as a manifestation of the need for security and the promotion of welfare. Tracing this tension back to an intrinsic ambivalence within the modern conception of individual liberty, which is both repressed and preserved by liberal conceptions of responsibility and punishment, Carvalhoproves that as long as this ambivalence remains unexamined, liberal law has the potential to both promote and undermine individual justice.Engaging with the dominant contemporary literature on criminal law, prevention, risk, security, and criminalisation, this volume deploys a theoretical perspective developed through a critical analysis of both classical and contemporary works of social and political theory. The book reveals that thepervasiveness of prevention in 21st century criminal justice systems represents not only the consequence of new and unprecedented features of contemporary politics and society, but also the manifestation of essential aspects of the liberal legal and political tradition.

This paper is the result of three interviews held in Paris, between the months of October and November 2015. Respondants were: the philosopher Marcel Gauchet, diretor of studies at the Ecole des Hautes Etudes EHESS; political scientist and historian of secularity, Philippe Portier, diretor of studies at the École Pratique des Hautes Études EPHE Paris-Sorbonne and historian Didier Da Silva, professor of history of ideas at the Institut Catholique de Paris. The goal pursued in the context of these interviews is (...) related to the understanding of a current perspective of religion output at the thought of Gauchet, the subject of my post-doctoral research at PUC Minas, Belo Horizonte, and at the National Program for Postdoctoral PNPD, Capes. The considerations which led the analysis proposed in this paper are guided by understanding effort of some of the characteristics of the religious phenomenon in the contemporary context. What we wonder and what is defined in this effort of understanding are the reconfigurations that mark the current stage of relations between politics and religion - reconfigurations demarcating the permeabilities and the limits of the overall spectrum of those relations. In addition, more particularly, what we present here are some thoughts on the condition of secularity and religion exit in the Brazilian context. (shrink)

We develop some ideas about gauge symmetry in the context of Maxwell’s theory of electromagnetism in the Hamiltonian formalism. One great benefit of this formalism is that it pairs momentum and configurational degrees of freedom, so that a decomposition of one side into subsets can be translated into a decomposition of the other. In the case of electromagnetism, this enables us to pair degrees of freedom of the electric field with degrees of freedom of the vector potential. Another benefit is (...) that the formalism algorithmically identifies subsets of the equations of motion that represent time-dependent symmetries. For electromagnetism, these two benefits allow us to define gauge-fixing in parallel to special decompositions of the electric field. More specifically, we apply the Helmholtz decomposition theorem to split the electric field into its Coulombic and radiative parts, and show how this gives a special role to the Coulomb gauge (i.e. div \((\mathbf{A}) = 0\) ). We relate this argument to Maudlin’s (Entropy, 2018. https://doi.org/10.3390/e20060465 ) discussion, which advocated the Coulomb gauge. (shrink)

In the 18th century, Guilielmus Piso arrives in Brazil as the archiater in the court of John Maurice of Nassau. Upon his return to Europe, he takes on the task of writing a descriptive treatise of these Western Indies. For this purpose, he makes use of the mental framework bequeathed by his education, setting up therefore the treatise On Airs, Waters and Places about Brazil. In the same manner and by the same means found in the homonymous treatise of the (...) Corpus Hippocraticum, and fortified by the authority of Latin (and Galenic) tradition, Piso undertakes an analysis of the man from this Land and his customs, taking as the axis of the “anthropological” part of his treatise the relation between a conception of nature that is merely an interpretation of the Hippocratic φύσις and the indolent ἦθος, which, by its turn, gave birth to a long-term imaginary lasting until the 21st century.

The Husserlian phenomenological approach to organisational research as a way to understand how collectives experience and mean their work context, is rarely used although, when it is, it often functions as a negative criticism of objectivist methods. The sociological potential of phenomenological concepts to enable understanding of subjective experience of social contexts, and the characterisation of those social contexts through ideal type construction, deserves to be used more extensively in a positive proposal of organisational research methodologies. However, a consistent phenomenological (...) approach—with its inherent qualities that enable the transcendental understanding of subjective phenomena and social objectivity—can be sociologically fruitful only if it benefits from accumulated sociological knowledge, realised by various approaches that discuss macro and micro aspects of organisations. The proposed phenomenological methodology considers both aspects. It takes account of social theories that consider the influences of both the macro environment and institutionalisation on structure and culture through their relationship with collective and individual action. Also, it performs collaboration between two close perspectives which recognise the importance of the subjective meanings of the individuals constituting the collective: Husserl’s transcendental phenomenology and Weber’s ideal type construction. It also discusses context, participant selection, the concepts of saturation and generalisation, and the applicability of the methodology. (shrink)

In contemporary academic philosophy, Chinese Philosophy remains a niche. This has a lot to do with its presentation, which often creates an impression of alienness and allegory, making its contribution, especially to analytical questions, not obvious. This paper examines how a change in presentation eases the inclusion of Chinese Philosophy into the mainstream. On the assumption that there has been an “activist turn” in the discipline in general, philosophical interest in a tradition that ranges from conceptual analysis, to ethics and (...) politics, but that is ultimately focused on motivating actions, becomes more relevant and pressing. Since, in much of Chinese Philosophy, the philosopher is an activist, if the wider discipline is indeed undergoing an “activist turn”, then there is a connection here that should be made. In this paper, the connection is explained using two examples, Mozi and Xu Fuguan. (shrink)

This article proposes that the propagation of vibrations could serve as a better model for understanding the transmission of affect than the flow, circulation or movement of bodies by which it is most often theorized. The vibrations (or idiomatically ‘vibes’) among the sound system audience (or ‘crowd’) on a night out on the dancehall scene in Kingston, Jamaica, provide an example. Counting the repeating frequencies of these vibrations in a methodology inspired by Lefebvre’s rhythmanalysis results in a Frequency Spectrogram. This (...) ranges from the sociocultural frequencies of nightly, weekly and seasonal cycles and circulations of musical style and fashion, to the material frequencies of the amplitudes and timbres of sound itself, with reggae’s signature low-pitched bass-line, to the corporeal frequencies of the flesh and blood of the dancehall ‘crowd’, pulsating with heartbeats and kinetic dance rhythms. The vibration model then addresses the intensities of affect in terms of auditory amplitudes, as with sonic dominance; feelings as frequencies; and the distinctive meaning of affect as timbre. This aims to encourage the radical impulse of the idea of affect to abandon the traditional envelope of the autonomous, self-consistent, rational individual. The meaning of affect is thus located in the ratio, proportions and patterning of vibrations, that is, outside the discourse of emotions or representation of feelings. (shrink)

This paper investigates the conceptual possibility for, and the institutions relating to a positive right of private property to data. To do so, it distinguishes between structured data, as a designator, and datapoints, which are data embedded in the timeline. The reasoning being explored here is: the agents generating datapoints – he source of the data – have a right to private property to the datapoints they generate. The agents, then, can choose to retain the datapoints or to sell them (...) to data-users, aggregators, etc. Once these data-users render property of data themselves, they can further market it. There are, however, challenges to this view. One is the relative high cost of managing private property to data versus the relative low cost of misappropriating data and datapoints. The other is network effects: more precisely, data created or enriched in networks. (shrink)

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

O objetivo deste estudo é identificar como a adoção aparece nas histórias de vida de indivíduos adotados e como eles normalizam suas experiências relacionadas à adoção. Focaliza-se a re-historiação do “eu” na narrativa e considera-se que o seu final é determinado por quem constrói a narrativa, não por eventos relatados cronologicamente. Os dados provêm das narrativas de dois indivíduos adotados, transcritas segundo convenções utilizadas na Análise da Conversa Etnometodológica, nas quais se destaca a presença dos eventos relacionados à adoção na (...) re-historiação dos pesquisados e na constituição de seus “eus” parciais, considerando também as características rítmicas e outras propriedades da fala em interação.

The History of Political Ideas by the German-American philosopher Eric Voegelin is a monumental work of around 2,600 pages. It remained unpublished during his lifetime, and it came to light through the American edition and the now completed Portuguese edition. Being the author of the first world edition of an abridged version of the History of Political Ideas ; the translator of the first three volumes of the 2012-2018 Portuguese edition; and the author of The civil philosophy of Eric Voegelin (...) I consider that the History of Political Ideas challenges the present climate of opinion: it subverts the dominant corrosive forces of moral relativism, intolerant neo-positivism, end-of-history obsessions, postmodernist deconstructions, agnosticism, nihilism, new age religions, and the all-pervasive ideology of money. Eric Voegelin achieves all this leading his readers from Antiquity to Modern Age. His monumental work begins with the “spiritual disintegration” of the Greek world, after the peak of Plato and Aristotle, a disintegration that ushered a long process of transition in the self-understanding of man in the Mediterranean world. The series goes through Middle Ages, R enaissance and Reformation as Voegelin analyzes the collapse of imperial Christianity, which led to the rise of autonomous reason and sectarian revolts that reached full development in later centuries. A new form of modern human consciousness replaced the Christian understanding of a divinely created closed cosmos. The collection ends - in a suspensive way - with “The Crisis and the Apocalypse of Man” focused on thinkers such as Comte, Bakunine and Marx; although they experienced true epiphanies, they become self-obsessed to the detriment of the world to which they refer. Such “Apocalypse of Man” must now be challenged, albeit with methodologies and hermeneutic principles other than those that Voegelin himself abandoned some decades ago. (shrink)

Whether for the republican president Sun Yat-sen or for the communist helmsman Mao Zedong, the legalist philosopher Hanfei (韓非), whose works marked the Qin Empire some 2200 years ago, still seems to be a source of inspiration. This paper traces the philosophy of Hanfei as a representative of political realism. In order to do so, these paper proceeds in three steps: First, realism is explained in terms of Hanfei, the “author” himself. Second, it is weighed how far his philosophy represents (...) a break with Confucianism and Daoism or whether it can adapt elements of these schools of thought despite all differences. Thirdly, the question will be addressed to what extent Hanfei’s political realism is also a resource to explain contemporary political thought in China. This paper claims that realism, in the Chinese context, began early as a response to Confucianism and Daoism. This response is marked by adaptation and change of themes but also as introduction of novel elements. Realism remains an important factor in Chinese political philosophy. (shrink)

Virtuous conduct is the philosophy of agency within Early Confucianism. Drawing on the ideas of Confucius, Mencius, and Xunzi, this book characterizes Early Confucianism as a progressive philosophy due to its human-centered program for social reform, its process view of self-cultivation, and its development.

Barbour’s interpretation of Mach’s principle led him to postulate that gravity should be formulated as a dynamical theory of spatial conformal geometry, or in his terminology, “shapes.” Recently, it was shown that the dynamics of General Relativity can indeed be formulated as the dynamics of shapes. This new Shape Dynamics theory, unlike earlier proposals by Barbour and his collaborators, implements local spatial conformal invariance as a gauge symmetry that replaces refoliation invariance in General Relativity. It is the purpose of this (...) paper to answer frequent questions about (new) Shape Dynamics, such as its relation to Poincaré invariance, General Relativity, Constant Mean (extrinsic) Curvature gauge, earlier Shape Dynamics, and finally the conformal approach to the initial value problem of General Relativity. Some of these relations can be clarified by considering a simple model: free electrodynamics and its dual shift symmetric formulation. This model also serves as an example where symmetry trading is used for usual gauge theories. (shrink)

In an accompanying paper Gomes, we have put forward an interpretation of quantum mechanics based on a non-relativistic, Lagrangian 3+1 formalism of a closed Universe M, existing on timeless configuration space \ of some field over M. However, not much was said there about the role of locality, which was not assumed. This paper is an attempt to fill that gap. Locality in full can only emerge dynamically, and is not postulated. This new understanding of locality is based solely on (...) the properties of extremal paths in configuration space. I do not demand locality from the start, as it is usually done, but showed conditions under which certain systems exhibit it spontaneously. In this way we recover semi-classical local behavior when regions dynamically decouple from each other, a notion more appropriate for extension into quantum mechanics. The dynamics of a sub-region O within the closed manifold M is independent of its complement, \, if the projection of extremal curves on \ onto the space of extremal curves intrinsic to O is a surjective map. This roughly corresponds to \, where \ is a linear projection. This criterion for locality can be made approximate—an impossible feat had it been already postulated—and it can be applied for theories which do not have hyperbolic equations of motion, and/or no fixed causal structure. When two regions are mutually independent according to the criterion proposed here, the semi-classical path integral kernel factorizes, showing cluster decomposition which is the ultimate aim of a definition of locality.
