Michael Walzer is one of the world's most important political thinkers. In this book, Toby J. Reiner provides the most wide-ranging and up-to-date introduction to his work available. Examining Walzer's multivarious writings and work, Reiner develops an illuminating new interpretation of his thought that no political theorist can afford to miss.

This article considers the nature of communitarian thought in late twentieth century Anglo-American political philosophy. It argues that communitarianism arose out of a critique of modernist theories of justice such as that of John Rawls shared by a group of writers committed to idealist principles that emphasised narrative approaches to the study of political thought, the importance of historical context, and popular participation in political life. It then focuses on one particular American strand of communitarian thought, exemplified by the work (...) of Michael Walzer and Michael Sandel, which draws on a tradition of radical democracy and, in so doing, helps both to create and to transform a new American republicanism. An important connection between Walzer and Sandel is that they share the view that egalitarian politics must draw on shared traditions of social criticism rather than on the abstract individualism that they associate with Rawls. A key difference is that Walzer's vision of American life is pluralist and enthusiastic about difference, whereas Sandel's is republican and concerned above all with fostering civic virtue and identification with the state and political community.

This paper argues that historians of ideas must, when seeking to reconstruct webs of beliefs, interpret texts as though they were performances. As this is particularly the case with dialogic texts, the paper focuses on Plato's dialogues to show that the arguments expressed therein cannot be taken as expressions of Plato's beliefs. Rather, such arguments seek to prompt thought in their readers and thus reveal beliefs indirectly. We must therefore revise Mark Bevir's account of the reconstruction of webs of beliefs (...) so that we construct a consistent web and then assume that to be the web of the author in question, rather than assuming that the web we construct is a consistent one. Consideration of Leo Strauss's argument that philosophers have often had to hide their meaning for fear of persecution, the paper concludes that its argument may apply to treatise-based writing as well as to dialogues. All texts include an element of the performative. (shrink)

Just-war theory has a long and distinguished history that stretches back to the Christian theologians of medieval Europe. Yet principles of just war must develop alongside social norms, standards of military practice and technology, and civilian-military relationships. Since World War II, and especially since American involvement in Vietnam, military ethics has developed into an academic cottage industry. As commonly taught to undergraduates and military practitioners, contemporary just-war theory seeks to ensure the political sovereignty and territorial integrity of nation-states. The theory (...) insists that the only just wars are defensive ones and forbids wars of national aggrandizement. On this view, because of the right to collective self-determination, wars must not seek to remake the world order, as that would undermine state sovereignty.In recent decades, however, cosmopolitan philosophers have challenged various aspects of the traditional edifice in an attempt to use just-war theory to enhance the protection of human rights around the world. Scholars have argued for greater scope for humanitarian intervention to protect individuals against their own government, for principles of justice after war to ensure that all states are legitimate, and most radically, for the responsibility of ordinary combatants to assess for themselves the justice of their military's cause. On this last argument, because combatants whose cause is just have done nothing to lose their immunity from harm, attacking them is unjust, and combatants whose cause is unjust cannot fight with discrimination.This publication surveys these recent developments, and it finds that they provide a radical challenge to both the theory and the practice of contemporary warfare. Of particular importance is its insistence on the need to strengthen international institutions, so as to provide combatants with an impartial perspective on their side's cause, and to strengthen military ethics education; and its suggestion that policies on dishonorable discharge be rethought. However, this monograph also challenges certain aspects of the new approach, suggesting important connections between military ethics and democratic theory and practice. (shrink)

This is not a work of mine. For some reason, I am unable to remove it from my page. It is a list of Dr. Reiner Schürmann's lecture notes for courses that he taught at the New School for Social Research (aka The New School).

We think we know what healers do: they build on patients' irrational beliefs and treat them in a 'symbolic' way. If they get results, it's thanks to their capacity to listen, rather than any influence on a clinical level. At the same time, we also think we know what modern medicine is: a highly technical and rational process, but one that scarcely listens to patients at all. In this book, ethnopsychiatrist Tobie Nathan and philosopher Isabelle Stengers argue that this commonly (...) posed opposition between traditional and modern medicine is misleading. They show instead that healers are interesting precisely because they don't listen to patients, using techniques of 'divination' rather than 'diagnosis'. Healers construct genuine therapeutic strategies by identifying the origins of symptoms in external forces, outside of the mind of the sufferer, and in this regard African healers are virtuosos. Though it may claim otherwise, modern medicine, for its part, is characterised by empiricism rather than rationality. What appears to be the pursuit of rationality is ultimately only a means to dismiss and exclude other forms of treatment. Blurring the distinctions between traditional and modern practices and drawing on perspectives from across the globe, this ethnopsychiatric manifesto encourages us to think in radically new ways about illness, challenging accepted notions on the relationship between sufferer and symptom. It will be of great interest to those working in medicine and healthcare, as well as anthropologists, social scientists and those in the humanities more broadly. (shrink)

Contentless experience involves an absence of mental content such as thought, perception, and mental imagery. In academic work it has been classically treated as including states like those aimed for in Shamatha, Transcendental, and Stillness Meditation. We have used evidence synthesis to select and review 135 expert texts from within the three traditions. In this paper we identify the features of contentless experience referred to in the expert texts and determine whether the experiences are the same or different across the (...) practices with respect to each feature. We identify 65 features reported or implied in one or more practices, with most being reported or implied in all three. While there are broad similarities in the experiences across the traditions, we find that there are differences with respect to four features and possibly many others. The main difference identified is that Shamatha involves substantially greater attentional stability and vividness. Another key finding is that numerous forms of content are present in the experiences, including wakefulness, naturalness, calm, bliss/joy, and freedom. The findings indicate that meditation experiences described as contentless in the academic literature can in fact involve considerable variation, and that in many and perhaps most cases these experiences are not truly contentless. This challenges classical understandings in academic research that in these so-called contentless experiences all content is absent, and that the experiences are therefore an identical state of _pure consciousness_ or consciousness itself. Our assessment is that it remains an open question whether the experiences aimed for in the three practices should be classed as pure consciousness. Implications of our analysis for neuroscientific and clinical studies and for basic understandings of the practices are discussed. (shrink)

Subpart B of 45 Code of Federal Regulations Part 46 (CFR) identifies the criteria according to which research involving pregnant women, human fetuses, and neonates can be conducted ethically in the United States. As such, pregnant women and fetuses fall into a category requiring “additional protections,” often referred to as “vulnerable populations.” The CFR does not define vulnerability, but merely gives examples of vulnerable groups by pointing to different categories of potential research subjects needing additional protections. In this paper, I (...) assess critically the role of this categorization of pregnant women involved in research as “vulnerable,” both as separate entities and in combination with the fetuses they carry. In particular, I do three things: (1) demonstrate that pregnant women qua pregnancy are either not “vulnerable” according to any meaningful definition of that term or that such vulnerability is irrelevant to her status as a research participant; (2) argue that while a fetus may be vulnerable in terms of dependency, this categorization does not equate to the vulnerability of the pregnant woman; and (3) suggest that any vulnerability that appends to women is precisely the result of federal regulations and dubious public perceptions about pregnant women. I conclude by demonstrating how this erroneous characterization of pregnant women as “vulnerable” and its associated protections have not only impeded vital research for pregnant women and their fetuses, but have also negatively affected the inclusion of all women in clinical research.

A common idea, both in ordinary discourse and in the desert literature, is that wages can be deserved. The thought is not only highly intuitive, but it is also often appealed to in order to explain various injustices in employment income – pay gaps, for instance. In this paper, I challenge the idea that income from employment is the kind of thing that can be deserved. I argue that once one gets clear on the metaphysics of jobs and wages within (...) the context of economic exchange more generally, there are natural principles concerning such exchanges which generate puzzles for that view. The puzzles, I argue, are especially acute for meritocrats who conceive of justice in wages in terms of desert. Additionally, I argue that appealing to dignity (rather than desert) offers better hope of explaining the kinds of injustices in wages that motivate the appeal to desert. In that case, no explanatory gap is left by abandoning the idea that wages can be deserved either, and so, I argue, we have good reason to doubt it. (shrink)

Shamatha, Transcendental, and Stillness Meditation are said to aim for “contentless” experiences, where mental content such as thoughts, perceptions, and mental images is absent. Silence is understood to be a central feature of those experiences. The main source of information about the experiences is texts by experts from within the three traditions. Previous research has tended not to use an explicit scientific method for selecting and reviewing expert texts on meditation. We have identified evidence synthesis as a robust and transparent (...) method that is suitable for this purpose. In this paper we use evidence synthesis based on expert texts to examine silence/quietness as a feature of the contentless experiences in the three practices. Objective criteria were used to select a sample of 135 expert texts. A database containing the expert descriptions of the meditation techniques and experiences was produced by extracting the relevant material from the publications and coding that material to differentiate individual features. The database, which forms part of the Supplementary Material for this paper, identifies each feature of the contentless experiences referred to in the expert texts, including silence/quietness. Our key finding is that the experts indicate silence/quietness has a particular connection with stillness, and the absence of concepts, mental activity/noise, thoughts, and disturbance. Further analysis leads to the following insights. The silence/quietness reflects the absence of thoughts and sounds, and this fits neatly with a conception of silence/quietness as the absence of internal and external noise. In some cases the terms silence and quietness may also reflect the absence of other disturbances such as non-auditory perceptions, mental images, and negative feelings. That would fit with a conception of silence/quietness as complete calm or absence of disturbance. It is not clear from the expert texts how silence/quietness is distinct from other features such as stillness that also reflect the absence of disturbances. As a separate matter, silence/quietness has connections with all the other features of the contentless experiences, but the closeness of the connections varies. Our work uncovers fine distinctions and ambiguities which lead to new research questions that can be explored in future studies. (shrink)

In providing a good foundation for mathematics, set theorists often aim to develop the strongest theories possible and avoid those theories that place undue restrictions on the capacity to possess strength. For example, adding a measurable cardinal to $ZFC$ is thought to give a stronger theory than adding $V=L$ and the latter is thought to be more restrictive than the former. The two main proponents of this style of account are Penelope Maddy and John Steel. In this paper, I’ll offer (...) a third account that is intended to provide a simple analysis of restrictiveness based on the algebraic concept of retraction in the category of theories. I will also deliver some results and arguments that suggest some plausible alternative approaches to analyzing restrictiveness do not live up to their intuitive motivation. (shrink)

As Laudan and Fine show, and Boyd concedes, the attempt to infer the truth of scientific realism from the fact that it putatively provides the best explanation of the instrumental success of science is circular, since what is to be shown is precisely the legitimacy of such abductive inferences. Hacking's "experimental argument for scientific realism about entities" is one of the few arguments for scientific realism that purports to avoid this circularity. We argue that Hacking's argument is as dependent on (...) inference to the best explanation (IBE), and therefore as weak, as the other realist arguments. (shrink)

Según la Regla de Atención que formula David Lewis, la mera consideración de una posibilidad que supondría que la proposición que creemos fuera falsa, basta, si no la podemos descartar y por muy improbable que ésta sea, para hacer desaparecer nuestro conocimiento de tal proposición.

Si la consideración de la posibilidad no descartada no afecta a nuestro grado de certeza previo, tal posibilidad no (...) puede hacer desaparecer nuestro conocimiento.According to David Lewis’s Rule of Attention, the mere fact of attending to a possibility,that we cannot discard, in which the proposition believed would be false, is sufficient, to make our knowledge of that proposition disappear, no matter how far-fetched that possibility may be. The aim of this paper is to criticize such a rule and to offer a much more moderate version of it. If attending to the non-ignored possibility does not affect our prior degree of certainty, such a possibility cannot make our knowledge disappear. (shrink)

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience with which the spectrum began. Hence the betterness relation admits cycles, threatening either transitivity or asymmetry of the relation. This (...) paper examines recent attempts to block the spectrum argument, using the idea that it is a mistake to affirm that every experience in the spectrum is worse than its predecessor: an alternative hypothesis is that adjacent experiences may be incommensurable in value, or that due to vagueness in the underlying concepts, it is indeterminate which is better. While these attempts formally succeed as responses to the spectrum argument, they have additional, as yet unacknowledged costs that are significant. In order to effectively block the argument in its most typical form, in which the first element is radically inferior to the last, it is necessary to suppose that the incommensurability is particularly acute: what might be called radical incommensurability. We explain these costs, and draw some general lessons about the plausibility of the available options for those who wish to save orthodox axiology from the spectrum argument. (shrink)

« La déconstruction, c’est la pulvérisation d’un socle spéculatif où la vie trouverait son assise, sa légitimation, sa paix. » Autrefois son élève, Reiner Schürmann identifie dans l’oeuvre de Heidegger un impensé, le principe d’anarchie. Contre cette métaphysique occidentale qu'il s'applique à déconstruire, le penseur de la présence aurait fait de l'être et de l'agir une seule et même question. Et sapé ainsi toute possibilité de définir un fondement rationnel sur lequel construire une philosophie pratique. Que l'agir humain, à (...) l'époque technologique, se trouve privé d'arché : voilà ce que cette étude majeure, lisant Heidegger à rebours, a permis de dévoiler. (shrink)

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies we can take today to safeguard humanity’s future. (shrink)

The orthodox view of the metaphysics of desert is that desert is a triadic relation that obtains between a subject, an object and a desert base. Not only is this view lacking in motivation, but conceiving of the desert base as part of the desert relation renders the concept of desert incoherent. Instead, desert should be thought of as a dyadic relation between a subject and an object, where desert bases are simply the grounds for dyadic desert facts.

In this report I provide an introduction to the burgeoning field of hypercomputation – the study of machines that can compute more than Turing machines. I take an extensive survey of many of the key concepts in the field, tying together the disparate ideas and presenting them in a structure which allows comparisons of the many approaches and results. To this I add several new results and draw out some interesting consequences of hypercomputation for several different disciplines.

Some risks have extremely high stakes. For example, a worldwide pandemic or asteroid impact could potentially kill more than a billion people. Comfortingly, scientific calculations often put very low probabilities on the occurrence of such catastrophes. In this paper, we argue that there are important new methodological problems which arise when assessing global catastrophic risks and we focus on a problem regarding probability estimation. When an expert provides a calculation of the probability of an outcome, they are really providing the (...) probability of the outcome occurring, given that their argument is watertight. However, their argument may fail for a number of reasons such as a flaw in the underlying theory, a flaw in the modeling of the problem, or a mistake in the calculations. If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect. We develop this idea formally, explaining how it differs from the related distinctions of model and parameter uncertainty. Using the risk estimates from the Large Hadron Collider as a test case, we show how serious the problem can be when it comes to catastrophic risks and how best to address it. (shrink)

The deliberative systems approach is a recent innovation within the tradition of deliberative democratic theory. It signals an important shift in focus from the political legitimacy produced within isolated and formal sites of deliberation (e.g., Parliament or deliberative mini-publics), to the legitimacy produced by a number of diverse interconnected sites. In this respect, the deliberative systems (DS) approach is better equipped to identify and address defects arising from the systemic influences of power and coercion. In this article, I examine one (...) of the least explored and least understood defects: the exclusion of non-speaking political actors generated by the uniform privileging of speech in all sites within a system. Using the examples of prefigurative protest, Indigenous refusal to deliberate, and the non-deliberative agency of disabled citizens, I argue that the DS approach allows theorists to better understand forms of domination related to the imposition of speech on those who are either unwilling or unable to speak.

The ubiquitous schema ‘All Fs are Gs’ dominates much philosophical discussion on laws but rarely is it shown how actual laws mentioned and used in science are supposed to fit it. After consideration of a variety of laws, including those obviously conditional and those superficially not conditional, I argue that we have good reason to support the traditional interpretation of laws as conditionals of some quantified form with a single object variable. I show how this conclusion impacts on the status (...) of ‘system laws’ and the significance of having only one object variable with regard to the relationship between laws and causal relations.

I describe three extant attempts to identify global external symmetries within a Humean framework with theorems of some or other deductive systematization of the world: the best system, a best meta-system, and a maximally simple system. Each has merits, but also serious flaws. Instead, I propose a view of global external symmetries as consequences of the structure of Humean-consistent world-making relations.

In lieu of an abstract, here is a brief excerpt of the content:Can Two Wrongs Make a Right?Toby Williamson (bio)"Service users, carers, and professionals disagree about the nature of mental disorder in startling new revelation!" On first appearances Fulford and Colombo's use of linguistic-analytic and empirical methods to demonstrate this point may not seem as if it is telling those in the mental health world anything that they do not already know. The bipolar/dialectical axis (choose your preferred term depending (...) on your ideological position) with the anti-psychiatry movement at one end and the biogeneticists at the other is both well-known and well-documented. Yet it is precisely that flippancy, and the practical implications that flow from it, that make this work so fundamentally important to the theory, application, and experience of mental health practice at the beginning of the twenty-first century.Discussions about different models of mental disorder usually play themselves out in arguments within services, or between services and service users and informal carers, about the most appropriate approach to take in addressing a service users needs, or in abstract discussions (often over a drink after work) about the nature of mental health and mental health problems. From blood and fur flying in the bull pit, to swallows endlessly chasing their tails high in the sky. Sadly, the results of this all too often are bitter and unresolved conflicts, different parties digging themselves even further into defensive, entrenched positions, and the least powerful (usually service users) suffering the most as a consequence. Both sides believe the other to be wrong yet cannot convince them of this; an example, albeit with slight variation, of two wrongs not making a right. Rarely are the debates grounded in a constructive, creative, and problem-solving approach on a day-to-day basis, partly because hitherto there does not seem to have been either sufficient empirical evidence to base this upon, or the conceptual as well as practical tools with which to grapple with the issues.Generally speaking, mainstream research in mental health has tended to focus on issues such as symptoms and treatment interventions (James and Burns 2002). However, surveys of service users' views still show considerable problems in the way services are received and experienced by users (Rose 2001). Other surveys, together with user-led research, such as Strategies for Living at the Mental Health Foundation, have also shown how the focus of users' concerns maybe very different to that of service providers (Faulkner and Layzell 2000; Nicholls et al, 2003; Repper 2000). Indeed, a piece of research carried out in the 1990s, which would probably still hold true today, showed that service users prioritized practical issues such as personal finance, housing, and social support, whereas professionals saw issues such as treatment and monitoring as being the highest priority (Shepherd, Murray, and Muijen 1995). Combining this, one might well argue that there is fairly clear evidence of the [End Page 159] differences in value bases and models of mental disorder deployed by service users and mental health professionals. However, actually trying to scientifically map this, and taking into account differences between professions, not to mention the views of informal carers, would appear to be a gargantuan task. Yet Fulford and Colombo appear to have very successfully done this in the research supporting this article, as well as the article itself. Their discussion of the concept of mental disorder, and the difficulties of defining it, not only effortlessly demonstrates the theoretical and philosophical problems that lie at the heart of psychiatry and mental health systems, of which Professor Fulford along with others has already written extensively (Dickenson and Fulford 2000), but also should resonate at a very practical level for most people who have been at the providing or receiving end of mental health services. But going beyond this they also provide perhaps the simplest, yet most effective solution—to embrace diversity and find ways of working with it, rather than running shy of it or even worse, attempting to homogenize it. As they say, "the difficulties in use presented by the concept of mental disorder are not a liability, heuristically speaking, but an asset" (Fulford and Colombo 2004, 132).The article is also very timely because...

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

As web instruction becomes more and more prevalent at universities across the country, instructors of ethics are being encouraged to develop online courses to meet the needs of a diverse array of students. Web instruction is often viewed as a cost-saving technique, where large numbers of students can be reached by distance education in an effort to conserve classroom and instructor resources. In practice, however, the reverse is often true: online courses require more of faculty time and effort than do (...) many traditional classes. Based on personal experience teaching an online course in health care ethics for students in the Allied Health Professions, it is evident that there are both benefits and challenges in teaching online courses, particularly in ethics. Examples of benefits are (1) the asynchronous nature of web instruction allows students to progress through the course at their own pace and at times that are convenient given their clinical responsibilities; (2) web courses allow for a standardization of content and quality of instruction over a diversity of programs; and (3) examples can be tailored to the differing experiences of students in the course. Some challenges to teaching online ethics courses include (1) the fact that online instruction benefits visual learners and disadvantages those lacking good reading comprehension or strong writing skills; (2) developing meaningful student-student and student-instructor interaction; and (3) teaching ethics involves teaching a process rather than a product. Allowing students to apply their knowledge to real-world cases in their disciplines and encouraging them to share experiences from clinical practice is an effective way to meet several of these challenges. Building an online community is another good way to increase the interaction of students and their engagement with the material. (shrink)

In his article "The Concept of Observation in Science and Philosophy" (1982), Dudley Shapere argues for an analysis of what it is for an object to be directly observed (observable). He does so by presenting two contrasting ways of observing the center of the sun. However, his examples, which are probabilistic in nature, are at odds with his analysis, which is absolute. I argue that of the three features of the examples which could serve as the basis for the analysis (...) only one--the amount of alteration to the information being transmitted--can plausibly do so. Having reworked Shapere's analysis on the basis of this feature, I show that the analysis still fails to provide a sufficient condition for observation. (shrink)

In late 2009, e-mails from a server at the Climate Research Unit at the University of East Anglia were released that showed some climate scientists in an unfavorable light. Soon this scandal was known as “Climategate” and a highly charged debate started to rage on blogs and in the mass media. Much of the debate has been about the question whether anthropogenic global warming was undermined by the revelations. But ethical issues, too, became part and parcel of the debate. This (...) article aims to contribute to this debate, assessing the e-mail affair in the light of two normative analyses of science, one proposed by Robert Merton, the second by a recent suggestion to use the concept of honest brokering in science policy interactions. On the basis of these analyses, different aspects of malpractice will be discussed and possible solutions will be suggested. (shrink)

This paper expands upon a way in which we might rationally doubt that there are multiple sizes of infinity.

The resultant theory provides an alternative philosophical perspective on the transfinite, but has limited impact on everyday (...) mathematical practice. (shrink)

It has often been noted that there is some tension between engaging in decision-making and believing that one’s choices might be predetermined. The possibility that our choices are predetermined forces us to consider, in our decisions, act-state pairs which are inconsistent, and hence to which we cannot assign sensible utilities. But the reasoning which justifies two-boxing in Newcomb’s problem also justifies associating a non-zero causal probability with these inconsistent act-state pairs. Put together these undefined utilities and non-zero probabilities entail that (...) expected utilities are undefined whenever it is a possibility that our choices are predetermined. There are three ways to solve the problem, but all of them suffer serious costs: always assume that, contrary to our evidence, the outcome of our present decision-making is not predetermined; give up the reasoning that justifies unconditional two-boxing in Newcomb’s problem; or allow epistemically impossible outcomes to contribute to expected utility, leading to the wrong results in a series of cases introduced by Ahmed :665–685, 2014a, Evidence, decision and causality, Cambridge University Press, Cambridge, 2014b). However they choose to respond, causal decision theorists cannot remain silent: the intuitive tension between decision-making and the possibility of predetermination can be made precise, and resolving it will require giving up something. Causal decision theorists have a predetermination problem. (shrink)

Interpretation is commonly used in mathematical logic to compare different theories and identify cases where two theories are for almost all intents and purposes the same. Similar techniques are used in the comparison between alternative logics although the links between these approaches are not transparent. This paper generalizes theoretical comparison techniques to the case of logical comparison using an extremely general approach to semantics that provides a very generous playing field upon which to make our comparisons. In particular, we aim (...) to develop the useful idea that interpretations should determine inner models. (shrink)
