Let λ denote a singular cardinal. Zeman, improving a previous result of Shelah, proved that $\square _{\lambda}^{\ast}$ together with 2 λ = λ⁺ implies $\lozenge _{S}$ for every S ⊆ λ⁺ that reflects stationarily often. In this paper, for a set S ⊆ λ⁺, a normal subideal of the weak approachability ideal is introduced, and denoted by I[S; λ]. We say that the ideal is fat if it contains a stationary set. It is proved: 1. if I[S; (...) λ] is fat, then $\text{NS}_{\lambda ^{+}}$ ↾ S is non-saturated; 2. if I[S; λ] is fat and 2 λ = λ⁺, then $\lozenge _{S}$ holds; 3. $\square _{\lambda}^{\ast}$ implies that I[S; λ] is fat for every S ⊆ λ⁺ that reflects stationarily often; 4. it is relatively consistent with the existence of a supercompact cardinal that $\square _{\lambda}^{\ast}$ fails, while I[S; λ] is fat for every stationary S ⊆ λ⁺ that reflects stationarily often. The stronger principle $\lozenge _{\lambda ^{+}}^{\ast}$ is studied as well. (shrink)

Contrary to comparativist critics of ideal theory, I argue that ideal institutions become relevant for issues of nonideal theory through their role as part of the ideal guidance approach (IGA). So far, the most important argument against the IGA has been the second-best argument. However, this argument is only damaging for the IGA under certain conditions: Firstly, when the ideal is not realizable, and, secondly, when the path to the ideal does not contain the second-best (...) world. Since it is an empirical question whether this is the case, the article discusses the empirical relevance of the second-best argument. By employing causal mechanisms identified in the institutionalist literature – path dependence and institutional complementarity – I argue that the IGA actually offers better prospects for the evaluation of nonideal alternatives than the comparative approach. This is, because the latter systematically excludes the information of how an ideal institutional design looks like from consideration. I also discuss and reject the objection that a more comprehensive version of the comparative approach could take these issues into consideration: Such an approach is either epistemically infeasible or very similar to the IGA.

This paper looks at the nature of idealizations and representational structures appealed to in the context of the fractional quantum Hall effect, specifically, with respect to the emergence of anyons and fractional statistics. Drawing on an analogy with the Aharonov–Bohm effect, it is suggested that the standard approach to the effects— the topological approach to fractional statistics—relies essentially on problematic idealizations that need to be revised in order for the theory to be explanatory. An alternative geometric approach is outlined and (...) endorsed. Roles for idealizations in science, as well as consequences for the debate revolving around so-called essential idealizations, are discussed. (shrink)

Scientific models typically contain idealizations, or assumptions that are known not to be true. Philosophers have long questioned the nature of idealizations: Are they heuristic tools that will be abandoned? Or rather fictional representations of reality? And how can we reconcile them with realism about knowledge of nature? Immanuel Kant developed an account of scientific investigation that can inspire a new approach to the contemporary debate. Kant argued that scientific investigation is possible only if guided by ideal assumptions—what he (...) calls “regulative ideas”. These ideas are not true of objects of nature, and yet they are not heuristic tools or fictional represen- tations. They are necessary rules governing the construction and assessment of scientific explanations. In this paper, I suggest that some idealizations can be interpreted as having necessary regulative value and as being compatible with scientific realism. I first analyze the puzzle of the nature of idealization and present the main approaches to this topic in the literature. Second, I reconsider the puzzle vis-a-vis a restricted, Kantian definition of idealization and a novel characterization of the relation between idealization and truth. Finally, I discuss in detail an example of idealization (the Hardy-Weinberg equilibrium) along the suggested Kantian lines. (shrink)

It's standard in epistemology to approach questions about knowledge and rational belief using idealized, simplified models. But while the practice of constructing idealized models in epistemology is old, metaepistemological reflection on that practice is not. Greco argues that the fact that epistemologists build idealized models isn't merely a metaepistemological observation that can leave first-order epistemological debates untouched. Rather, once we view epistemology through the lens of idealization and model-building, the landscape looks quite different. Constructing idealized models is likely the best (...) epistemologists can do. Once one starts using epistemological categories like belief, knowledge, and confidence, the realm of idealization and model-building is entered. We can object to a model of knowledge by pointing to a better model, but in the absence of a better model, the fact that a framework for epistemologizing theorizing involves simplifications, approximations, and other inaccuracies-the fact of its status as an idealized model-is not in itself objectionable. Once we accept that theorizing in epistemological terms is inescapably idealized, a number of intriguing possibilities open up. Greco defends a package of epistemological views that might otherwise have looked indefensibly dismissive of our cognitive limitations-a package according to which we know a wide variety of facts with certainty, including what our evidence is, what we know and don't know, and what follows from our knowledge.

There exists a standard view of Kant’s position on global order and this view informs much of current Kantian political theory. This standard view is that Kant advocates a voluntary league of states and rejects the ideal of a federative state of states as dangerous, unrealistic, and conceptually incoherent. This standard interpretation is usually thought to fall victim to three equally standard objections. In this essay, I argue that the standard interpretation is mistaken and that the three standard objections (...) miss their target. Kant does advocate the establishment of a non-coercive league of states, at least in his mature political writings (such as Perpetual Peace and the Metaphysics of Morals), but he does so for different reasons than is usually thought and without rejecting the ideal that a world federation of states eventually be realized. I end by indicating how Kant’s revised view can be made productive for present-day philosophical purposes. (shrink)

I reinterpret Bohr's attitude towards quantum mechanical formalism and its empirical content, based on his understanding of the correspondence principle and its approximate applicability. I suggest that Bohr understood complementarity as a limitation imposed by the commutation relations upon the applicability of the idealizations which had grounded the use of the correspondence principle. By discussing this interpretation against the contemporary background of discussions regarding “naïve realism” about operators (as observables), I suggest that a Bohrian view on the empirical content of (...) quantum mechanical operators may provide a middle ground between complete contextualism and an untenable realism about quantum properties.

These days, the radicalization of young people is above all viewed as a security risk. Almost all research into this phenomenon has been carried out from a legal, criminological or socio-psychological perspective with a focus on detecting and containing the risks posed by radicalization. In the light of the political developments since September 11, 2001, this is entirely understandable but perhaps not altogether wise. Research and theory development from a pedagogical perspective can also make a significant contribution towards a better (...) understanding of radicalization processes and possibly offer new points of departure for intervention strategies. On the basis of five typical cases, the authors examine the role of educators, social workers and teachers, and the problems they face when dealing with young people with extreme ideals. This article attempts to provide insight into the pedagogical conditions for the development of extreme ideals and suggests starting points for developing effective countermeasures. (shrink)

Ecologists attempt to understand the diversity of life with mathematical models. Often, mathematical models contain simplifying idealizations designed to cope with the blooming, buzzing confusion of the natural world. This strategy frequently issues in models whose predictions are inaccurate. Critics of theoretical ecology argue that only predictively accurate models are successful and contribute to the applied work of conservation biologists. Hence, they think that much of the mathematical work of ecologists is poor science. Against this view, I argue that model (...) building is successful even when models are predictively inaccurate for at least three reasons: models allow scientists to explore the possible behaviors of ecological systems; models give scientists simplified means by which they can investigate more complex systems by determining how the more complex system deviates from the simpler model; and models give scientists conceptual frameworks through which they can conduct experiments and fieldwork. Critics often mistake the purposes of model building, and once we recognize this, we can see their complaints are unjustified. Even though models in ecology are not always accurate in their assumptions and predictions, they still contribute to successful science. (shrink)

Healthy eating policies have become a hot and thorny domain of public concern because they affect people’s liberties, life prospects, and public expenditures. However, what policies state institutions may legitimately enforce is a controversial matter. Is state paternalism for the sake of public health permissible? Could people be incentivized to eat in a healthier manner? Barnhill and Bonotti’s recent book tackle these issues in a manner that seeks to combine the liberal values of state neutrality and antipaternalism, as well as (...) the effectiveness and legitimacy of food policies. To do so, they rely on the accessibility model of public reason. Although Barnhill and Bonotti’s proposal fills an important gap in the field and the accessibility model of public reason overcomes some strictures of the Rawlsian account, their account of public reason faces some practical challenges. Indeed, the institutionalization of their framework seems to need the figure of a moderator of a deliberative panel. However, this figure would create a tension between the public reason framework and the common requirements of deliberative accounts. (shrink)

Philosophers of language are increasingly engaging with derogatory terms or slurs. Only few theorists take such language as a starting point for addressing puzzles in philosophy of language with little connection to our real-world problems. This paper aims to show that the political nature of derogatory language use calls for non-ideal theorising as we find it in the work of feminist and critical race scholars. Most contemporary theories of slurs, so I argue, fall short on some desiderata associated with (...) a non-ideal approach. They neglect crucial linguistic or political aspects of morally and politically significant meaning. I argue that a two-stage project is necessary to understand the perniciousness of slurs: accounting for the derogatory content of derogatory terms in general and, additionally, explaining the communicative function of slurs more specifically. I end by showing how inferentialism is well-suited to account for the content of derogatory terms whilst allowing for further explanations of the communicative functions of slurs. (shrink)

This book provides both an introduction to the philosophy of scientific modeling and a contribution to the discussion and clarification of two recent philosophical conceptions of models: artifactualism and fictionalism. These can be viewed as different stances concerning the standard representationalist account of scientific models. By better understanding these two alternative views, readers will gain a deeper insight into what a model is as well as how models function in different sciences. Fictionalism has been a traditional epistemological stance related to (...) antirealist construals of laws and theories, such as instrumentalism and inferentialism. By contrast, the more recent fictional view of models holds that scientific models must be conceived of as the same kind of entities as literary characters and places. This approach is essentially an answer to the ontological question concerning the nature of models, which in principle is not incompatible with a representationalist account of the function of models. The artifactual view of models is an approach according to which scientific models are epistemic artifacts, whose main function is not to represent the phenomena but rather to provide epistemic access to them. It can be conceived of as a non-representationalist and pragmatic account of modeling, which does not intend to focus on the ontology of models but rather on the ways they are built and used for different purposes. The different essays address questions such as the artifactual view of idealization, the use of information theory to elucidate the concepts of abstraction and idealization, the deidealization of models, the nature of scientific fictions, the structural account of representation and the ontological status of structures, the role of surrogative reasoning with models, and the use of models for explaining and predicting physical phenomena.

In this document, we describe the concepts of ideal semantics and stage semantics for abstract argumentation in terms of argument labellings. The difference between the traditional extensions approach and the labelling approach is that where the former only identifies the sets of accepted arguments, the latter also identifies the rejected arguments as well as the arguments that are neither accepted nor rejected. So far, the labellings approach has been successfully applied to complete, grounded, preferred, stable and semi-stable semantics, as (...) well as to the concept of admissibility. In the current paper, we continue this line of research by showing that ideal semantics and stage semantics can also be described in terms of argument labellings. (shrink)

The aim of this manuscript is to introduce the \((\alpha,\beta)\)-hesitant fuzzy set and apply it to semigroups. In this paper, as a generalization of the concept of hesitant fuzzy sets to semigroup theory, the concept of \((\alpha,\beta)\)-hesitant fuzzy subsemigroups of semigroups is introduced, and related properties are discussed. Furthermore, we define and study \((\alpha,\beta)\)-hesitant fuzzy ideals on semigroups. In particular, we investigate the structure of \((\alpha,\beta)\)-hesitant fuzzy ideal generated by a hesitant fuzzy ideal in a semigroup. In addition, (...) we also introduce the concepts of \((\alpha,\beta)\)-hesitant fuzzy semiprime sets of semigroups, and characterize regular semigroups in terms of \((\alpha,\beta)\)-hesitant fuzzy left ideals and \((\alpha,\beta)\)-hesitant fuzzy right ideals. Finally, several characterizations of regular and intra-regular semigroups by the properties of \((\alpha,\beta)\)-hesitant ideals are given. (shrink)

Do liberal states have a moral duty to admit immigrants? According to what has been called the “conventional view”, this question is to be answered in the negative. One of the most prominent critics of the conventional view is Joseph Carens. In the past 30 years Carens’ contributions to the open borders debate have gradually taken on a different complexion. This is explained by the varying “ideality” of his approaches. Sometimes Carens attempts to figure out what states would be obliged (...) to do under otherwise perfectly just conditions (i.e., he attempts to establish an ideal). At other times, he is more interested in what to do, given the (not fully just) world that we actually live in. In my view, the relevance of the ideal/non-ideal theory debate to the open borders debate (and the ethics of migration more generally) has not yet received sufficient attention. My aim in this paper therefore is to show in detail how Carens’ varying approaches affect his critique of the conventional view. To this effect I analyze three of his papers: “Aliens and Citizens: The Case for Open Borders” (1987), “Realistic and Idealistic Approaches to the Ethics of Migration” (1996), and “Who Should get in? The Ethics of Immigration Admissions” (2003). (shrink)

Phylogenetic models traditionally represent the history of life as having a strictly-branching tree structure. However, it is becoming increasingly clear that the history of life is often not strictly-branching; lateral gene transfer, endosymbiosis, and hybridization, for example, can all produce lateral branching events. There is thus motivation to allow phylogenetic models to have a reticulate structure. One proposal involves the reconciliation of genealogical discordance. Briefly, this method uses patterns of disagreement – discordance – between trees of different genes to add (...) lateral branching events to phylogenetic trees of taxa, and to estimate the most likely cause of these events. I use this practice to argue for: (1) a need for expanded accounts of multiple-models idealization, (2) a distinction between automatic and manual de-idealization, and (3) recognition that idealization may serve the meso-level aims of science in a different way than hitherto acknowledged.

Gendered socialization has prompted numerous attempts to redefine what counts as an autonomous choice. However, there is strong disagreement among feminist theorists over the criteria to identify cases of autonomy impairment _vis-à-vis_ the embeddedness of individuals in patriarchal cultures. I argue that this focus on choice and autonomy has often neglected the costs of non-compliance to social norms and the trade-offs that women make to flourish within their community. Even if we were to find an effective way to determine whether (...) a self-regarding choice calls for state interference because of its socialized nature, we would still lack a sufficient justification for interfering with women’s choices. To justify political action, my claim is that we should also look at the effects that preference interference would have on women within their societal context. Consequently, I develop a non-ideal feminist account aimed chiefly at analysing the costs of proposed feminist change. I shall focus in particular on women’s engagement with practices of body modification for the sake of conforming to gendered standards of appearance, such as cosmetic surgery and hymen restoration. In both cases, I argue that blanket bans risk backfiring into a form of double-jeopardy for those who are already the most vulnerable to gendered oppression, hence they are not justified. However, this does not imply passively accepting the status quo but urges us to reconsider new ways to offset transition costs, making resistance to social norms a collectively shared endeavour rather than a burden that exclusively befalls the most vulnerable.

This paper is a review of Suarez, M. (ed.) Fictions in Science (Routledge).

The main purpose of this essay is to explore the relationship between the incommensurability of paradigms or general theories, a thesis due to Kuhn and Feyerabend, and the idealizations and abstractions that permeate concepts and fundamental laws of physical theories. One can find some unrealistic or idealizational suppositions underlying the semantic level of the differences between the conceptual vocabularies of incommensurable theories, on which these theories rest. This kind of suppositions relates to the idealizations and abstractions involved in forming concepts (...) and formulating laws. Generally, the fundamental laws of physical theories have an abstract and idealized character. Physical theories contain conceptual networks of kind concepts and quantitative concepts, which are interconnected by several sorts of relationships. The discrepancies between such conceptual network, and their underlying assumptions, of alternative paradigms or theories make their comparison at a theoretical level, that is, their commensurability implausible. That at once strengthens the incommensurability thesis and further supports it. In addition, it follows that Kuhn’s philosophy of science indeed involves a version of conceptual or epistemological relativism about science. (shrink)

Early normative studies of human behavior revealed a gap between the norms of practical rationality (what humans ought to do) and the actual human behavior (what they do). It has been suggested that, to close the gap between the descriptive and the normative, one has to revise norms of practical rationality according to the Quinean, engineering view of normativity. On this view, the norms must be designed such that they effectively account for behavior. I review recent studies of human perception (...) which pursued normative modeling and which found good agreement between the normative prescriptions and the actual behavior. I make the case that the goals and methods of this work have been incompatible with those of the engineering approach. I argue that norms of perception and action are observer-independent properties of biological agents; the norms are discovered using methods of natural sciences rather than the norms are designed to fit the observed behavior.

Robin McKenna argues that we need to make space for an approach to epistemology that avoids the idealizations typical of the field.

The Vitruvian Man is a metaphor for the “ideal man” by feminist posthuman philosopher Rosi Braidotti (2013) as a proxy for eurocentric humanist ideals. The first half of this paper extends Braidotti's concept by thinking about the metaphor of the “ideal nurse” (Vitruvian nurse) and how this metaphor contributes to racism, oppression, and burnout in nursing and might restrict the professionalization of nursing. The Vitruvian nurse is an idealized and perfected form of a nurse with self‐sacrificial language (re)producing (...) self‐sacrificing expectations. The second half of this paper looks at how regulatory frameworks (using the example of UK's Nursing and Midwifery Council Code of Conduct) institutionalize the conditions of possibility through collective imaginations. The domineering expectations found within the Vitruvian nurse metaphor and further codified by regulatory frameworks give rise to boredom and burnout. The paper ends by suggesting possible ways to diffract regulatory frameworks to practice with affirmative ethics and reduce feelings of self‐sacrifice and exhaustion among nurses. (shrink)

Joseph Heath (2014) argues that the contribution of competitive markets to Pareto-efficiency generates moral constraints that apply to business managers. Heath argues that ethical behavior on the part of management consists in avoiding profit-seeking strategies which, under conditions of perfect competition, would decrease Pareto-efficiency.

Ideal epistemologists investigate the nature of pure epistemic rationality, abstracting away from human cognitive limitations. Non-ideal epistemologists investigate epistemic norms that are satisfiable by most humans, most of the time. Ideal epistemology faces a number of challenges, aimed at both its substantive commitments and its philosophical worth. This paper explains the relation between ideal and non-ideal epistemology, with the aim of justifying ideal epistemology. Its approach is meta-epistemological, focusing on the meaning and purpose of (...) epistemic evaluations. I provide an account on which the fundamental difference between ideal and non-ideal epistemic evaluations is that only the non-ideal epistemic ‘ought’ implies any substantive ‘can’. I argue that only ideal epistemic evaluations are ‘normatively robust’: they are neither conventional nor seriously context-sensitive. Non-ideal epistemic evaluations are normatively non-robust, exhibiting both conventionality and serious context-sensitivity from an interesting variety of distinct sources. For this reason, non-ideal epistemic evaluations won’t characterize the fundamental nature of epistemic rationality. Non-ideal epistemic rationality depends, not merely on what’s epistemically valuable, but also on modally contingent epistemic conventions and contextually contingent constraints on epistemic options. If we want a normatively robust theory of epistemic rationality, ideal epistemology is the only game in town. (shrink)

Peoples often question the relevance of spiritualism in their modern life. They want to know why they should know what they are within and why should they bother to change themselves. With rapid changes in the socio-economic aspects of life all over the world, peoples are under intense pressure, and are seeking something, which will help them to successfully deal with union with the universal and transcendent existence. Today many people are shifting to spiritual approach to life but relevant number (...) does not know how. We all desire a work experience that can fit neatly with our personal lives. We all seek balance. Too often however people’s work life overpowers the rest if their life. And when that happens, we can very easily find ourselves struggling to keep up in all areas of our lives. Life is not all-play –no –work. Neither it is all-work-no-play. It has its own course of mixed actions. Work culture also plays an important role in human life. It means work-related activities and the meanings attached to such activities in the framework of norms and values regarding work these activities, norms and values are generally conceptualized in an organization. Understanding this chemistry and accepting the facts as its, is the starting point of a better life. When this happens the discussion has developed into a full-fledged philosophical one. And we come to ethics or moral philosophy and spiritualism. In this chapter we will study the philosophical outlook of work as a moral ideal in the form of karma. (shrink)

This book argues that the major traditions in the philosophy of language have mistakenly focused on highly idealized linguistic contexts. Instead, it presents a non-ideal foundational theory of language that contends that the essential function of language is to direct attention for the purpose of achieving diverse social and political goals. Philosophers of language have focused primarily on highly idealized linguistic contexts in which cooperative agents are working toward the shared goal of gaining information about the world. This approach (...) abstracts away from important issues like power, ideology, social position, and diversity of goals which are crucial to explaining linguistic phenomena both at the semantic and pragmatic levels. This book begins by examining the work of some of the pioneers of this tradition--primarily David Lewis, Paul Grice, and Robert Stalnaker. The author shows that various problems have their source in idealizations made at the foundational level of linguistic theory and proposes to rebuild from the ground-up. She presents a non-ideal foundational theory of language which retains the major insights of traditional frameworks while rejecting the social idealizations that guide them. Then, she explores the social and political applications of her account to issues such as dog whistling, propaganda, slurs and racist speech, silencing, and manipulation. Non-Ideal Foundations of Language will appeal to researchers and advanced students in philosophy of language who are interested in the social and political applications of language, as well as traditional metasemantic theory.

Second edition of the introductory guidebook to the basic principles of constructing sound arguments and criticising bad ones. Non-technical in approach, it is based on 186 examples, which Douglas Walton, a leading authority in the field of informal logic, discusses and evaluates in clear, illustrative detail. Walton explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical responses. This edition takes into account (...) many developments in the field of argumentation study that have occurred since 1989, many created by the author. Drawing on these developments, Walton includes and analyzes 36 new topical examples and also brings in work on argumentation schemes. Ideally suited for use in courses in informal logic and introduction to philosophy, this book will also be valuable to students of pragmatics, rhetoric, and speech communication. (shrink)

Many criticisms of epistemic logic have centered around its use of devices such as idealized knowers with logical omniscience and perfect self-knowledge. One possible response to such criticisms is to say that these idealizations are normative devices, and that epistemic logic tells us how agents ought to behave. This paper will take a different approach, treating epistemic logic as descriptive, and drawing the analogy between its formal models and idealized scientific models on that basis. Treating it as descriptive matches the (...) way in which some philosophers, including one of its founders, Jaako Hintikka, have thought about epistemic logic early in its history. Further, the analogy between the two fields will give us a way to defuse criticisms that see epistemic logic as unrealistic. For example, criticizing models of epistemic logic in which agents know all propositional tautologies as being unrealistic would be like criticizing frictionless planes in physics for being unrealistic. Each one would certainly be an unsuitable model for studying some kinds of phenomena, but is entirely appropriate for others. After outlining the analogy between epistemic and scientific models, we will discuss some ways in which idealizations are used by different research programs in epistemic logic. (shrink)

McKenna’s critique (rather than criticisms) of idealized approaches to epistemology is an important contribution to the literature. In this brief discussion, I set out his main concerns about more idealized approaches, within and beyond social epistemology, before turning to some issues I think he neglects. I suggest that it’s important to pay attention to the prestige hierarchy in philosophy, and to how that hierarchy can serve ideological purposes. The greater prestige of more abstract approaches plays a role in determining what (...) issues and what voices we attend to. (shrink)

This article intends to show that ideology is always organized systemically by undertaking the opposition between conformity and diversity as its fundamental criterion. In order to underpin this hypothesis, the present article examines the inner structure of five classic ideologies, that can be understood as ideal ideological types. The analysis reveals that ideologies do not form a system because at the core of any ideology there is a key-concept not determined nor influenced by the key concepts of other ideologies.

In this paper, we take up two objections Raymond Geuss levels against John Rawls' ideal theory in Philosophy and Real Politics. We show that, despite their fundamental disagreements, the two theorists share a common starting point: they both reject doing political philosophy by way of applying an independently derived moral theory; and grapple with the danger of unduly privileging the status quo. However, neither Rawls' characterization of politics nor his ideal theoretical approach as response to the aforementioned danger (...) is adequate - or so we argue. Moreover, contrary to received opinion, Geuss' political philosophy is the more reflective and the more philosophical of the two. In a final section, we highlight another agreement: both think that political philosophers should develop conceptual innovations as a way of clarifying and overcoming practical problems. We demonstrate that Geuss could offer a number of reasons for finding Rawls' conceptual innovations wanting. (shrink)

Idealization is commonly understood as distortion: representing things differently than how they actually are. In this paper, we outline an alternative artifactual approach that does not make misrepresentation central for the analysis of idealization. We examine the contrast between the Hodgkin-Huxley (1952a, b, c) and the Heimburg-Jackson (2005, 2006) models of the nerve impulse from the artifactual perspective, and argue that, since the two models draw upon different epistemic resources and research programs, it is often difficult to tell which features (...) of a system the central assumptions involved are supposed to distort. Many idealizations are holistic in nature. They cannot be locally undone without dismantling the model, as they occupy a central position in the entire research program. Nor is their holistic character mainly related to the use of mathematical and statistical modeling techniques as portrayed by Rice (2018, 2019). We suggest that holistic idealizations are implicit theoretical and representational assumptions that can only be understood in relation to the conceptual and representational tools exploited in modeling and experimental practices. Such holistic idealizations play a pivotal role not just in individual models, but also in defining research programs. -/- . (shrink)

Two approaches to understanding the idealizations that arise in the Aharonov–Bohm effect are presented. It is argued that a common topological approach, which takes the non-simply connected electron configuration space to be an essential element in the explanation and understanding of the effect, is flawed. An alternative approach is outlined. Consequently, it is shown that the existence and uniqueness of self-adjoint extensions of symmetric operators in quantum mechanics have important implications for philosophical issues. Also, the alleged indispensable explanatory role of (...) said idealizations is examined via a minimal model explanatory scheme. Last, the idealizations involved in the AB effect are placed in a wider philosophical context via a short survey of part of the literature on infinite and essential idealizations. (shrink)

Recently, there has been growing interest in methodological issues of non-ideal theoretical philosophy. While some explicitly commit to non-ideal theorising, others doubt that there is anything useful about the ideal/non-ideal distinction in theoretical philosophy. The aim of this paper is twofold. On the one hand, I propose a way of doing non-ideal theoretical philosophy, once we realise how limited certain idealised projects are. Since there is a big overlap between projects that are called non-ideal (...) and applied, the second aim is to distinguish between these categories in order to show that applied theoretical philosophy is only worth pursuing if it operates in a non-ideal framework. I argue that we should be pluralistic about possible non-ideal theories and view the ideal/non-ideal differences as a matter of degree, rather than kind. As an example, I show how my version of non-ideal theory is useful to a concrete debate in philosophy of language. My proposal allows us to identify already existing non-ideal approaches to linguistic meaning and encourages us to further engage in the debate on non-ideal theoretical philosophy. (shrink)
