This paper proposes a classification of the intertheoretic relations in physics by bringing out the conditions for a relation of reduction which is eliminative, so that a theory reduced in terms of reductionism is superfluous in principle, and by distinguishing such a relation from another one based on comparison, which will be called neighbourhood of theories; the latter is a neighbouring relation between theories and is not able to support claims of eliminative reductionism. In the first part, it (...) will be argued that this differentiation between neighbourhood and eliminative reduction permits an adequate classification of the intertheoretic relations in physics. By means of this differentiation, the second part discusses reductionism and shows that there are indeed some historical examples of reduction in the aforementioned sense, but that modern physical theories are typically only neighbouring.

Many countries encourage immigration, yet almost without exception they impose medical conditions on the admissibility of prospective immigrants. This paper examines the ethical defensibility of this practice. It argues that the neighbourhood principle, which states that we owe a greater duty to neighbours than to strangers, when properly understood, extends to all human beings, that economic and safety considerations play only a limited role in ethically underwriting an exclusionary policy, and that medical immigration criteria should be harmonized with (...) treatment eligibility criteria for citizens of the relevant countries themselves.

The paper explains how Gettier’s conclusion can be reached on general theoretical grounds within the framework of epistemic logic, without reliance on thought experiments. It extends the argument to permissive conceptions of justification that invalidate principles of multi-premise closure and require neighbourhood semantics rather than semantics of a more standard type. The paper concludes by recommending a robust methodology that aims at convergence in results between thought experimentation and more formal methods. It also warns against conjunctive definitions as sharing (...) several of the drawbacks of disjunctive definitions. (shrink)

All standard epistemic logics legitimate something akin to the principle of closure, according to which knowledge is closed under competent deductive inference. And yet the principle of closure, particularly in its multiple premise guise, has a somewhat ambivalent status within epistemology. One might think that serious concerns about closure point us away from epistemic logic altogether—away from the very idea that the knowledge relation could be fruitfully treated as a kind of modal operator. This, however, need not be (...) so. The abandonment of closure may yet leave in place plenty of formal structure amenable to systematic logical treatment. In this paper we describe a family of weak epistemic logics in which closure fails, and describe two alternative semantic frameworks in which these logics can be modelled. One of these—which we term plurality semantics—is relatively unfamiliar. We explore under what conditions plurality frames validate certain much-discussed principles of epistemic logic. It turns out that plurality frames can be interpreted in a very natural way in light of one motivation for rejecting closure, adding to the significance of our technical work. The second framework that we employ—neighbourhood semantics—is much better known. But we show that it too can be interpreted in a way that comports with a certain motivation for rejecting closure.

En Belgique, comme dans d’autres pays, l’insécurité s’impose dans les débats publics depuis le début des années 1990. Mais que recouvre cette notion ? Que nous dit-elle des risques sociaux et physiques vécus par les habitants des quartiers populaires ? Comment est-elle construite politiquement ? L’analyse de la mise en œuvre concrète des nouveaux dispositifs sociopénaux nous permet d’étudier comment, en se centrant sur la petite délinquance urbaine, ils réduisent la complexité de la question de l’insécurité, participent d’une approche gestionnaire (...) des risques et produisent des effets sociaux ambigus. L’instauration de ces nouveaux dispositifs et leur approche des risques liés à l’insécurité révèle l’importation, dans l’action publique, de principes de management jusqu’alors propres à l’entreprise.Insecurity has become a key item of public debate in Belgium, as well as in other countries, since the early 1990s. But what does this notion embrace ? What does it tell us about the social and physical risks run by the residents of working-class neighbourhoods ? How is it construed and dealt with politically ? Analysis of the actual implementation of new social and criminal policies enables us to study how these measures, in focusing on petty urban offences, reduce the complexity of the issue of public safety, participate in a managerial approach to these risks, and produce ambiguous social effects. The institution of these new measures and their way of approaching risks related to the feeling of insecurity reveals the importance of the use of management principles in government action that were until now specific to corporate activity.

Theories of networked individualism and forms of urban alienation challenge the continued purpose and relevance of conventional community tools in urban neighbourhood. However, the majority of urban residents surveyed in this research still believe that there are people living in their immediate neighbourhood who may share their interests or who are at least personally compatible, but they do not know them. Web-based community networking systems have the potential to facilitate intra-neighbourhood interaction and support community-building efforts. Community networking (...) studies have shown that technical connectivity alone does not ensure community and that new and weak communities do not benefit from community networking systems as much as existing and strong communities do. This paper builds on these findings to present a methodology combining principles of participation, animation and design. This approach builds on intrinsic motivation in residents to find out about and meet one another in a private and inobtrusive way. It encourages residents to take social ownership of the community-building process and the community network. The approach recognises the network qualities in the communicative ecology of urban residents and supplements collective approaches towards community-building with personalised networking strategies.

Land Ethics, Multilinguistic and Multicultural Communities of the 21 Century Guido Verstraeten Satakunta University of Applied Sciences, Suomi, Finland -/- The modern society is challenged by recent migration coming all over the world. Due to the basic rational principles of the modern nation the Western countries are faced with a disentangle of the societal coherence. The Newtonian conception of space-time, the secularization of the civil society, the extraterritorial cosmopolitism and the unilinear and homogeneous conception of progress seem incompatible with the (...) conception about life and society of the new immigrants. However the original population lost the cosy link with the familiar neighbourhood to which they are supposed to belong. This feelings of alienation of the part of the autochthonic people produce adversary reactions against foreigners of any walk and vice versa. Moreover populist politic parties recuperate this situation and impose a leitkultur to the traditional political life. -/- On the contrary we suggest to adopt a new conception of space, time , civil society, care and progress. Inspired by Leopold´s landethics we suggest an ecological philosophical basis for society building, based on the Leibnizian conception of space-time, the phenomenological relationship with the territory and a broad conception of civil society including civil virtue with respect to non-human life and landscape.

Philosophical romanticism is the view that, in maintaining out forms of life, we are engaged in the endless task of “acknowledging the human” in reading and being read by others. Winch's discussions of “human nature” and the principle of universalizability in ethics should discourage us from imputing such romanticism to his work. On the other hand, his discussions of generality in “the human” and the human neighbourhood might tempt one to do so. Winch's contemplative conception of philosophy should, (...) in the end, count against this temptation. His work is a passionate example of doing conceptual justice to different readings of “the human”. (shrink)

Drawing substantially on the arguments put forward by the contributors to this Special Issue, this final article examines the two main purposes of the common school in contemporary western societies: to develop a set of shared values and a unified sense of citizenship, on the one hand, and to iron out disadvantage and equalise opportunities, on the other. Four main justifications for the common school are discussed—its symbolic value, its compatibility with liberal values, its inclusiveness and its provision of practical (...) opportunities to learn to live together. Nevertheless, the common school faces a number of challenges, including how much freedom of choice to allow parents, how to interpret the principle of equality in practice, how to devise a common curriculum that meets the needs of all students and how to respond to the apparent inequalities of the neighbourhood school. It is argued that the biggest dilemma facing the common school is a cultural one: that is, finding a balance between the need to respect the diverse cultural identities of its students and the need to develop a common set of loyalties and shared national identity at the same time. An examination of the case of Muslims in England suggests that intentionally or otherwise the common school is still in the business of assimilating minorities into a new identity through processes very similar to those of the melting pot. The article concludes by warning that continuing this policy may result in stronger resistance in the future. (shrink)

It is known that Maxwell’s electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies (...) is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet. In the conductor, however, we find an electromotive force, to which in itself there is no corresponding energy, but which gives rise—assuming equality of relative motion in the two cases discussed—to electric currents of the same path and intensity as those produced by the electric forces in the former case. Examples of this sort, together with the unsuccessful attempts to discover any motion of the earth relatively to the “light medium,” suggest that the phenomena of electrodynamics as well as of mechanics possess no properties corresponding to the idea of absolute rest. They suggest rather that, as has already been shown to the first order of small quantities, the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good.1 We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status of a postulate, and also introduce another postulate, which is only apparently irreconcilable with the former, namely, that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body..

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S believes . S thus knows despite her false (...) belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed. (shrink)

This Open Access book explains the philosophy, design principles, and community organization of Decidim and provides essential insights into how the platform works. Decidim is the world leading digital infrastructure for participatory democracy, built entirely and collaboratively as free software, and used by more than 500 institutions with over three million users worldwide. -/- The platform allows any organization (government, association, university, NGO, neighbourhood, or cooperative) to support multitudinous processes of participatory democracy. In a context dominated by corporate-owned digital (...) platforms, in the era of increasing social structuring via Artificial Intelligence, Decidim stands as a public or community owned platform for collective human intelligence. Yet, the project is much more than its technological features. Decidim is in itself a crossroad of the various dimensions of the networked society, a detailed practical map of its complexities and conflicts. Theauthors distinguish three general dimensions of the project: (1) the political - shedding light on the democratic model that Decidim promotes and its impact on public policies and organizations, (2) the technopolitical - explaining how this technology is democratically designed and managed to produce and protect certain political effects, and (3) the technical - presenting the conditions of production, operation, and success of the project. This book systematically covers those three levels in an academically sound, technologically consistent, and politically innovative manner. Serving as a useful resource and handbook for the use of Decidim, it will not only appeal to students and scholars interested in participatory and digital democracy but also to professionals, policy-makers, and a wider audience interested in learning more about the Decidim platform.

At the moment of his death, Jean Meslier not only bequeathed to posterity a Memoir in which he will openly declare his materialistic atheism, but also two letters addressed to the priests of his neighbourhood. In those letters, which can be read as a preface to his work, he urges his colleagues to undeceive themselves Christianity`s mistakes, unveil the mystery of inequity and enlighten their parishioners on the principles of good sense and the straight natural reason, issues that afterwards (...) planted the seed of a future revolution. This is the first Spanish translation of the letters mentioned above and it is addressed to spread some of Meslier’s most unknown works. (shrink)

Political Philosophy of Kautilya: The Arthashastra and After offers a critical analysis of ideas and institutions as described in the ancient political economy text Arthashastra. It discusses the contributions of pre-Kautilyan, Kautilyan and post-Kautilyan political thought to the evolution and development of political theory, in general, and the impact and influence of Kautilya's contributions, in particular. The book examines Kautilya's theory of state, power, law and justice, administration, security, society and social well-being. This book examines the nature of the Kautilyan (...) state and argues that it followed the principles of a 'welfare state', a concept coined much later. It talks about the relationship between moralism and realism in the treatment of international relations. It highlights the Kautilyan strategies in dealing with a hostile environment in the neighbourhood and beyond, which will be particularly interesting to scholars of contemporary international relations.

The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its corollary process theory, active inference; and (2) if so, to assess which philosophical stance - in relation to the ontological and epistemological status of representations - is most appropriate. We focus on non-realist (deflationary and fictionalist-instrumentalist) approaches. We consider a deflationary account of mental representation, according to which the explanatorily relevant contents of (...) neural representations are mathematical, rather than cognitive, and a fictionalist or instrumentalist account, according to which representations are scientifically useful fictions that serve explanatory (and other) aims. After reviewing the free-energy principle and active inference, we argue that the model of adaptive phenotypes under the free-energy principle can be used to furnish a formal semantics, enabling us to assign semantic content to specific phenotypic states (the internal states of a Markovian system that exists far from equilibrium). We propose a modified fictionalist account: an organism-centered fictionalism or instrumentalism. We argue that, under the free-energy principle, pursuing even a deflationary account of the content of neural representations licenses the appeal to the kind of semantic content involved in the aboutness or intentionality of cognitive systems; our position is thus coherent with, but rests on distinct assumptions from, the realist position. We argue that the free-energy principle thereby explains the aboutness or intentionality in living systems and hence their capacity to parse their sensory stream using an ontology or set of semantic factors.

In 1997 John Broome presented the Collapsing Argument that was meant to establish that non-conventional comparative relations cannot exist. Broome's argument has faced a lot of scrutiny and a certain type of counterexample has been used to undermine it. Most of the counterexamples focus on the Collapsing Principle which plays a central role in Broome's argument. In this article we will take a closer look at the most common type of counterexample and propose how to adjust the Collapsing (...) class='Hi'>Principle in order to avoid objections based on these counterexamples. We argue that a weaker version of the Collapsing Principle is not susceptible to the classical counterexamples. Furthermore, after an explorative discussion about the intuitions behind the original principle, we show that this weaker formulation is at least as intuitive as the principle suggested by Broome.

The Acquaintance Principle is the principle according to which judgements concerning the aesthetic value of a work of art proffered by a critic must be based on the critic’s experience(s) or acquaintance with the work itself. The possible exception to this principle would be experiences obtained through other means of transmissibility, related in a particular way to the work in question, that can eventually provide the critic with an adequate basis for judging the artwork. However, recent philosophers (...) claimed that some works of conceptual art show the principle to be false. I argue that, if properly understood, the Acquaintance Principle is a truism, that works of conceptual art do not pose any particular problem to it, and also suggest some implications of the principle.

How can inferences from models to the phenomena they represent be justified when those models represent only imperfectly? Pierre Duhem considered just this problem, arguing that inferences from mathematical models of phenomena to real physical applications must also be demonstrated to be approximately correct when the assumptions of the model are only approximately true. Despite being little discussed among philosophers, this challenge was taken up by mathematicians and physicists both contemporaneous with and subsequent to Duhem, yielding a novel and rich (...) mathematical theory of stability with epistemological consequences.

I discuss the relationship between different versions of the equivalence principle in general relativity, among them Einstein's equivalence principle, the weak equivalence principle, and the strong equivalence principle. I show that Einstein's version of the equivalence principle is intimately linked to his idea that in GR gravity and inertia are unified to a single field, quite like the electric and magnetic field had been unified in special relativistic electrodynamics. At the same time, what is now (...) often called the strong equivalence principle, related to the local validity of special relativity, can also be found in Einstein's writings, albeit by a different name and clearly separated from what he calls the equivalence principle. I discuss both the development of Einstein's thoughts on the different versions of the equivalence principle, their relationship to the relativity principle, as well as later reflections and variants proposed.

In Bayesian epistemology, the problem of the priors is this: How should we set our credences (or degrees of belief) in the absence of evidence? That is, how should we set our prior or initial credences, the credences with which we begin our credal life? David Lewis liked to call an agent at the beginning of her credal journey a superbaby. The problem of the priors asks for the norms that govern these superbabies. -/- The Principle of Indifference gives (...) a very restrictive answer. It demands that such an agent divide her credences equally over all possibilities. That is, according to the Principle of Indifference, only one initial credence function is permissible, namely, the uniform distribution. In this paper, we offer a novel argument for the Principle of Indifference. I call it the Argument from Accuracy. (shrink)

Can Rawls’s theory provide a framework for assessing obligations to future generations? Extending the veil of ignorance so that participants in the original position do not know to which generation they belong appears to fail in this endeavour. Earlier generations cannot improve their situation by “cooperating” with later generations. Such circumstances, lacking mutuality, leave no room for an agreement or contract. Nevertheless, the original position can be reconstructed so as to model relations of mutuality between generations even if these are (...) absent from the real world. This chapter assesses earlier attempts to do this and provides a rationale for viewing the just savings principle as a clause in the full formulation of the difference principle. (shrink)

The Principle of Sufficient Reason says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability (...) argument and Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics. (shrink)

It is argued that recent discussion of the principle of the identity of indiscernibles (PII) and quantum mechanics has lost sight of the broader philosophical motivation and significance of PII and that the `received view' of the status of PII in the light of quantum mechanics survives recent criticisms of it by Muller, Saunders, and Seevinck.

The epistemology of dialectical materialism emphasizes two characteristic features of the picture of the world existing in our minds. First, it presents itself as reflection, i.e., as an image of an objective reality that exists independent of our consciousness. Secondly, this picture provides a reflection of the real world and the regularities of its development that is only approximately complete. The following comment by Lenin is of fundamental significance in this connection: "Cognition is man's reflection of nature, but it is (...) not a simple, not a direct, not a complete reflection, but a process involving a series of abstractions, the shaping and formation of concepts, laws, and the like, various concepts, laws, etc. and embraces, conditionally and approximately, the universal regularity of nature which is eternally moving and developing".

An important question in epistemology is whether the KK principle is true, i.e., whether an agent who knows that p is also thereby in a position to know that she knows that p. We explain how a “transparency” account of self-knowledge, which maintains that we learn about our attitudes towards a proposition by reflecting not on ourselves but rather on that very proposition, supports an affirmative answer. In particular, we show that such an account allows us to reconcile a (...) version of the KK principle with an “externalist” or “reliabilist” conception of knowledge commonly thought to make that principle particularly problematic.

Curie’s Principle says that any symmetry property of a cause must be found in its effect. In this article, I consider Curie’s Principle from the point of view of graphical causal models, and demonstrate that, under one definition of a symmetry transformation, the causal modeling framework does not require anything like Curie’s Principle to be true. On another definition of a symmetry transformation, the graphical causal modeling formalism does imply a version of Curie’s Principle. These results (...) yield a better understanding of the logical landscape with respect to the relationship between Curie’s Principle and graphical causal modeling. (shrink)

Excerpt from The Fundamental Principle of Fichte's Philosophy The purpose of this monograph is to make a careful study of Fichte's conception of the ultimate principle. In his various writings the principle appears under many different names. 'The Ego, ' 'the Idea of the Ego, ' 'the moral world-order, ' 'God, ' 'the Absolute, ' 'Being, ' 'the Light, ' are some of the phrases by which it is most commonly designated. It is not the main purpose (...) of this study to examine tile much discussed question of the relation between the two periods of Fichte's philosophy. But the question is so intimately connected with the problem which I have undertaken that some discussion of it is inevitable. I have tried, however, to keep well within the limits of my theme, and instead of considering the relation between the two periods in all its aspects, have sought merely to determine how far the conception of the fundamental principle which we find in Fichte's later writings differs from that which appears in the earlier ones. The references to Fichte's writings are to the Sammtliche Werke (Berlin, 1845-1846, 8 vols.) and to the Nachgelassene Werke (Bonn, 1834-1835, 3 vols.). References to the Sammtliche Werke are indicated by the letters S. W.; to the Nachgelassene Werke, by the letters N. W. References to the Kritik der remen Vernunft arc indicated by the letters A (for the First Edition) and B (for the Second). All other references to Kant's writings are made to Hartenstein's second edition of the Sammtliche Werke (Leipzig, 1867-1868, 8 vols.) and are indicated by the letter H.

We propose a principle of sustainability to complement established principles used for justifying healthcare resource allocation. We argue that the application of established principles of equal treatment, need, prognosis and cost-effectiveness gives rise to what we call negative dynamics: a gradual depletion of the value possible to generate through healthcare. These principles should therefore be complemented by a sustainability principle, making the prospect of negative dynamics a further factor to consider, and possibly outweigh considerations highlighted by the other (...) principles. We demonstrate how this principle may take different forms, and show that a commitment to sustainability is supported by considerations internal to the ethical principles already guiding healthcare resource allocation. We also consider two objections. The first of these, we argue, is either based on implausible assumptions or begs the question, whereas the second can be adequately accommodated by the principle we propose. (shrink)

Reichenbach’s Common Cause Principle is the claim that if two events are correlated, then either there is a causal connection between the correlated events that is responsible for the correlation or there is a third event, a so called (Reichenbachian) common cause, which brings about the correlation. The paper reviews some results concerning Reichenbach’s notion of common cause, results that are directly relevant to the problem of how one can falsify Reichenbach’s Common Cause Principle. Special emphasis will be (...) put on the question of whether EPR-type correlations can have an explanation in terms of Reichenbachian common causes. Most of the results to be recalled indicate that falsifying Reichenbach’s Common Cause Principle is much more tricky than one may have thought and that, contrary to some claims in the literature, there is no conclusive proof yet that the EPR correlations predicted by ordinary, non-relativistic quantum mechanics cannot have a common cause; furthermore, recent results about possible Reichenbachian common causes of correlations predicted by quantum field states between spacelike separated local observable algebras in algebraic quantum field theory strongly indicate that there may very well exist Reichenbachian common causes of superluminal correlations predicted by quantum field theory.

Le principe d’incertitude, qui a pris une extraordinaire importance dans la science contemporaine, révèle l’impossibilité des affirmations si fréquentes, que le monde physique et l’expérience sensible sont les seules choses qui comptent. Ce principe montre aussi combien est illégitime la tendance à considérer comme objectives et concrètes les hypothèses de travail.
