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)

On a contemporary Humean-influenced view, the responses of suitably idealized appreciators are presented as tracking, or even determining, facts about artistic value. Focusing on the intra-personal case, this paper argues that facts about the refinement and reconfiguration of aesthetic character together with the manner in which autobiography and character are implicated in artistic appreciation make it de facto unlikely that we can reliably come to know how our ideal counterpart would respond to a given artwork. Attribution of superhuman abilities to (...) our ideal counterpart partially addresses this worry, but undermines a central feature of the theoretical motivation for the idealizing model. Insofar as response-dependent accounts of artistic value are inextricably tied to an idealizing view of critics, we have reason to reject them. (shrink)

Can an AGI create a more intelligent AGI? Under idealized assumptions, for a certain theoretical type of intelligence, our answer is: “Not without outside help”. This is a paper on the mathematical structure of AGI populations when parent AGIs create child AGIs. We argue that such populations satisfy a certain biological law. Motivated by observations of sexual reproduction in seemingly-asexual species, the Knight-Darwin Law states that it is impossible for one organism to asexually produce another, which asexually produces another, and (...) so on forever: that any sequence of organisms (each one a child of the previous) must contain occasional multi-parent organisms, or must terminate. By proving that a certain measure (arguably an intelligence measure) decreases when an idealized parent AGI single-handedly creates a child AGI, we argue that a similar Law holds for AGIs. (shrink)

It is commonly thought that subjectivists about welfare must claim that the favorable attitudes whose satisfaction is relevant to your well-being are those that you would have in idealized conditions (e.g. ones in which you are fully informed and rational). I argue that this is false. I introduce a non-idealizing subjectivist view, Same World Subjectivism, that accommodates the two main rationales for idealizing: those given by Peter Railton and David Sobel. I also explain why a recent argument from Dale Dorsey (...) fails to show that subjectivists must idealize. Because Same World Subjectivism is a plausible non-idealizing view, subjectivists about welfare needn't idealize. (shrink)

This paper explores one way in which the meta-problem may shed light on existing debates about the hard problem (though not directly on the hard problem itself). I'll argue that the possibility of a suitable agent without problem intuitions would undercut the dialectical force of arguments against physicalism. Standard antiphysicalist arguments begin from intuitions about what's ideally conceivable, and argue from there to the falsity of physicalism. For these arguments to be dialectically effective, there must be a shared conception of (...) what ideal conceivability consists in. Unfortunately, proposed accounts of ideal conceivability all make reference to an unexplained 'intuitive' notion of idealization. Consideration of the meta-problem reveals that, when it comes to the hard problem, intuitions about idealization are essentially theory-laden. There is no neutral basis for determining whether agents with or without problem intuitions are more rationally ideal. (shrink)

Some theorists—including Elizabeth Anderson, Gerald Gaus, and Amartya Sen—endorse versions of 'public reason' as the appropriate way to justify political decisions while rejecting 'ideal theory'. This chapter proposes that these ideas are not easily separated. The idea of public reason expresses a form of mutual 'civic' respect for citizens. Public reason justifications for political proposals are addressed to citizens who would find acceptable those justifications, and consequently would comply freely with those proposals should they become law. Hence public reasoning involves (...) 'local ideal theorizing': the justification of political proposals includes their consideration and evaluation under conditions of compliance with them by the citizens to whom those justifications are addressed. Local ideal theorizing, moreover, can lead to 'full ideal theorizing', wherein citizens outline and evaluate an amended version of their society’s 'basic structure'. This argument is illustrated by some recent empirical work on inequality within the United States. (shrink)

In recent years, the value-freeness of science has come under extensive critique. Early objectors to the notion of value-free science can be found in Rudner and Churchman, later objections occur in Leach and Gaa, and more recent critics are Kitcher, Douglas, and Elliott. The goal of this paper is to examine and critique two arguments opposed to the notion of a value-free science. The first argument, the uncertainty argument, cites the endemic uncertainty of science and concludes that values are needed (...) to give direction to scientific investigation. The second, or moral argument, cites the fact that scientists have moral obligations just like everyone else, and.. (shrink)

It is tempting and not at all uncommon to find the striking—even noble—visage of an Ideal Observer staring out from the center of Hume's moral theory. When Hume claims, for instance, that virtue is “ whatever mental action or quality gives to a spectator the pleasing sentiment of approbation ,” it is only natural to think that he must have in mind not just any spectator but a spectator who is fully informed and unsullied by prejudice. And when Hume writes (...) that “the true standard of taste and beauty” is set by those who exhibit “[s]trong sense, united to delicate sentiment, improved by practice, perfected by comparison, and cleared of all prejudice,” he appears to describe a character no ordinary human could actually possess. Indeed, Hume's frequent appeals to the moral sentiments of spectators, his insistence that those sentiments depend upon taking “the general survey,” and his persistent invocation of the general point of view , together make the temptation almost irresistible.

It is proposed that we use the term “approximation” for inexact description of a target system and “idealization” for another system whose properties also provide an inexact description of the target system. Since systems generated by a limiting process can often have quite unexpected, even inconsistent properties, familiar limit systems used in statistical physics can fail to provide idealizations, but are merely approximations. A dominance argument suggests that the limiting idealizations of statistical physics should be demoted to approximations.

In this article we aim to open a new line of debate about religion in public schools by focusing on religious ideals. We begin with an elucidation of the concept ‘religious ideals’ and an explanation of the notion of reasonable pluralism, in order to be able to explore the dangers and positive contributions of religious ideals and their pursuit on a liberal democratic society. We draw our examples of religious ideals from Christianity and Islam, because these religions have most adherents (...) in Western liberal democracies that are the focus of this article. The fifth and most important section ‘‘Reasonable pluralism and the inclusion of religious ideals in public secondary schools’’ provides three arguments for our claim that public schools should include religious ideals, namely that they are important to religious people, that they are conducive for the development of pupils into citizens of a liberal democracy, and that the flourishing of pupils as adults is advanced by encountering religious ideals. We also offer a more practical reason: religious ideals can more easily be included within public education than religious dogmas and rules. (shrink)

Central to Confucian teachings in the Analects is the ideal of self-cultivation—in particular that of the junzi 君子 (“gentleman” “nobleman”) ideal. At the same time that Confucius recommends that individuals follow such an ideal, he also places limits on who actually might attain it. By examining statements involving such terms as the junzi, the “petty man” ( xiao ren 小人), and the “masses” ( min 民, or zhong 眾), or common people, this essay highlights the sociopolitical and gender restrictions informing (...) one of the most basic, yet lofty, ethical goals of the text. A new means is also offered of discussing these socially delimited discrepancies in moral cultivation by referring to leading, or self-determining agency in association with junzi on the one hand, and to conformist agency for women and common people on the other.

The ‘Kantian ideal’ is often misunderstood as invoking individual autonomy rather than rational self-legislation. Le Morvan and Stock’s otherwise insightful discussion of ‘Medical learning curves and the Kantian ideal’, for example, draws the mistaken inference that that ideal is inconsistent with the realities of medical practice. But it is not. Rationally to be a patient entails accepting its necessary conditions, one of which is the ineliminable existence of medical learning curves. Their rational necessity, therefore, offers no grounds against a Kantian (...) understanding of how morality might function in the practgice of medicine. (shrink)

Artificial intelligence (AI) is increasingly relied upon by clinicians for making diagnostic and treatment decisions, playing an important role in imaging, diagnosis, risk analysis, lifestyle monitoring, and health information management. While research has identified biases in healthcare AI systems and proposed technical solutions to address these, we argue that effective solutions require human engagement. Furthermore, there is a lack of research on how to motivate the adoption of these solutions and promote investment in designing AI systems that align with values (...) such as transparency and fairness from the outset. Drawing on insights from psychological theories, we assert the need to understand the values that underlie decisions made by individuals involved in creating and deploying AI systems. We describe how this understanding can be leveraged to increase engagement with de-biasing and fairness-enhancing practices within the AI healthcare industry, ultimately leading to sustained behavioral change via autonomy-supportive communication strategies rooted in motivational and social psychology theories. In developing these pathways to engagement, we consider the norms and needs that govern the AI healthcare domain, and we evaluate incentives for maintaining the status quo against economic, legal, and social incentives for behavior change in line with transparency and fairness values.

David Enoch, in his paper “Why Idealize?”, argues that theories of normative reasons that hold that normative facts are subject or response-dependent and include an idealization condition might have a problem in justifying the need for idealization. I argue that at least some response-dependence conceptions of normative reasons can justify idealization. I explore two ways of responding to Enoch’s challenge. One way involves a revisionary stance on the ontological commitments of the normative discourse about reasons. To establish this point, (...) I argue by analogy with the case of color perception. To make the analogy, it suffices to show that even if colors are response-dependent properties, it does not follow that some kind of idealization cannot be introduced to specify the truth conditions of color ascriptions. The second route involves the denial of Enoch’s contention that our normative discourse is implicitly committed to a realist ontology. I adduce reasons for thinking that our normative discourse only presupposes a possibility of misrepresentation. However, this feature of the normative discourse does not favor robustly objectivist as opposed to response-dependence accounts of normative reasons. Thus, I argue that proponents of response-dependence accounts can use this feature to answer the question of why to idealize. (shrink)

Eva Erman and Niklas Möller have recently presented a trenchant critique of my (2015) argument that ideal normative theories are uninformative for certain practical purposes. Their criticisms are largely correct. In this note, I develop the ideas behind my earlier argument in a way that circumvents their critique and explains more clearly why ideal theory is uninformative for certain purposes while leaving open the possibility that it might be informative for other purposes.

Science is the study of our world, as it is in its messy reality. Nonetheless, science requires idealization to function—if we are to attempt to understand the world, we have to find ways to reduce its complexity. Idealization and the Aims of Science shows just how crucial idealization is to science and why it matters. Beginning with the acknowledgment of our status as limited human agents trying to make sense of an exceedingly complex world, Angela Potochnik moves on to explain (...) how science aims to depict and make use of causal patterns—a project that makes essential use of idealization. She offers case studies from a number of branches of science to demonstrate the ubiquity of idealization, shows how causal patterns are used to develop scientific explanations, and describes how the necessarily imperfect connection between science and truth leads to researchers’ values influencing their findings. The resulting book is a tour de force, a synthesis of the study of idealization that also offers countless new insights and avenues for future exploration. (shrink)

My aim in this paper is twofold. First, I challenge the view that ideal normative principles offer appropriate guidelines for our efforts to identify morally progressive institutional reform strategies. I shall call this view the "ideal guidance approach." Second, I develop an alternative methodological approach to specifying nonideal normative principles, which I call the "failure analysis approach." I contrast these alternatives using examples from the global justice literature.

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual conditionals that can exhibit different degrees of contingency. We use the idea of possible worlds to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, it is this structure what helps explain why idealizations, despite being deformations of reality, are so successful (...) in scientific practice. (shrink)

In this paper, I show how idealizations contribute to social activities in science, such as the recruitment of experts to a research project. These contributions have not been explicitly discussed by recent philosophical accounts of scientific idealization. These accounts have focused on how idealizations influence activities like scientific theorization, explanation, and modeling. Other accounts focus on how idealizations influence policy-making and science communication. I expand these accounts by exploring the uses of idealized phylogenetic trees in science. Trees are not only (...) useful for improving our understanding and public communication of evolutionary history, but they also help with the organization of laboratories and collaboration among scientists. Attending to the relation between idealizations and these social practices in science matters. It can help us understand why idealized models become entrenched and why certain social practices change over time. (shrink)

In this paper I argue that the way to reduce the power of overdemanding beauty ideals is not to advocate that individuals have a ‘duty to resist’, a duty to stop engaging in appearance enhancing practices and body work.

I then give four further additional arguments against advocating a ‘duty to resist’ as an effective means to challenge dominant beauty norms. First, that as (...) a tactic it is ineffective. Second, it is an individual approach which divides and silences. Third, it induces shame and blame, and undermines effective collective action. Fourth, it fails to recognize the privilege of the group norms which make resistance possible. (shrink)

This paper deals with the following questions: What features of modern natural science are responsible for the fact that, of all forms of science, this form is technologically exploitable? The three notions: concept of nature, epistemic ideal, and experiment, suggest the most important components of my answer. I will argue, first, that only the peculiar interplay of the modern concept of nature with an epistemic ideal attuned to it can cast experiment in the specific, highly central role it plays in (...) the pursuit of knowledge about nature. It will then become clear that the form of science in which experiment plays such a role will, necessarily, prove technologically exploitable. (shrink)

Idealizations are ubiquitous in physics. They are distortions or falsities that enter into theories, laws, models, and scientific representations. Various questions suggest themselves: What are idealizations? Why do we appeal to idealizations and how do we justify them?

The aim of the paper is to propose an understanding of idealization in terms of Nowak’s unitarian metaphysics. Two natural interpretations of the procedure are critically discussed and rejected as inadequate. The first account of idealization is unable to explain why idealized factors cease to exert influence on the investigated magnitude. The second account of idealization solves this problem but does so at the cost of blurring the distinction between idealization and abstruction. Moreover, it faces the consequence that the process (...) of idealization instead of leading to a sharper understanding of phenomena will normally result in making the picture more and more probabilistic. I propose a third account of idealization in unitarian terms that solves all three problems. (shrink)

In this paper, I examine Kant’s reception of and solution to the problem of the unity of the political will. I propose that Kant distances himself from the modern paradigmatic foundations of sovereignty principally with his theses of the ideality of the general will and of the apriority of the justification of popular sovereignty. My interpretative hypothesis is that Kant solves the problem by grounding sovereignty in a conceptual element which is new in the history of political philosophy, i. e. (...) the a priori unified omnilateral will. In section IV, I explain why my reading of the ideality of the general will can respond to seemingly plausible objections arising from Kant’s own texts and how it works in the face of concrete political states of affairs.

Charles Mills has argued against ideal theory in political philosophy on the basis that it contains idealizations. He calls for political philosophers to do more nonideal theory, namely political theory that pays more attention to the most visible oppressions in society, such as those based on race, gender, and class. Mills's argument relies on a distinction between idealization and abstraction. Idealizations involve adding false assumptions to one's model, which is unacceptable, whereas abstractions merely leave out details without undermining descriptive power. (...) By studying formal models of injustice, I argue that the idealization/abstraction distinction is unhelpful. Either the distinction exists only relative to one's modeling purposes, or all models in political theory contain idealizations. Either way, the distinction does not help Mills's cause. Furthermore, there are arguments from philosophy of science for the epistemic benefits of idealizations. However, Mills's call for greater emphasis on the most visible mechanisms of oppression can be supported without relying on an idealization/abstraction distinction. I provide three alternative reasons for why we should prefer political theories that place more emphasis on race-, class-, and gender-based oppression. (shrink)

While puzzles concerning the epistemic significance of disagreement are typically motivated by looking at the widespread and persistent disagreements we are aware of, almost all of the literature on the epistemic significance of disagreement has focused on cases idealized peer disagreement. This fact might itself be puzzling since it doesn’t seem that we ever encounter disagreements that meet the relevant idealized conditions. In this paper I hope to somewhat rectify this matter. I begin by closely examining what an idealized case (...) of peer disagreement looks like and what the Equal Weight View (EWV) of disagreement claims about the epistemic significance of such disagreements. After briefly defending the verdicts of the EWV in idealized disagreements I proceed to unpack the implications of stripping away the idealized conditions. In doing I show both why it is important to focus on idealized cases of peer disagreement and what we can learn from such cases that applies to the everyday cases of disagreement of which we are very familiar.

Educators who are reflective about their educational endeavours ask themselves questions like: What is the aim of education? What moral, methodological, or other constraints govern our educational activities and efforts? One natural place to look for answers is in the philosophy of education, which (among other things) tries to provide systematic answers to these questions. One general answer offered by the philosophy of education is that the aim of education consists in fostering the development of students' rationality. On this view, (...) education has as its fundamental task both the development of students' reasoning ability, and also the fostering of a complex of attitudes, habits of mind, dispositions and character traits, such that students are not only able to reason well; they also care about reasons, and organize their beliefs, judgments and actions in accordance with the deliverances of the reasoned evaluation of reasons. Argumentation theory is also concerned with the analysis of the power and convicting force of reasons. When do reasons for a claim warrant acceptance of that claim? By what criteria are reasons evaluated? How are these criteria themselves justified? Such questions as these are the meat and potatoes of argumentation theory, which, in pursuing these questions, promises to shed light on the character of rationality as the aim of education. Rationality, which links education and argumentation theory, provides educators with a reason to care about argumentation-if rationality can be cogently defended as an educational ideal. In this paper I will try to provide such a defense, and in doing so explain why educators should care about argumentation. The defense will be a moral one: I will argue that we are morally obliged to endeavour to foster the rationality of students, because that is what is required to meet our obligations to treat students with respect as persons. I will also consider some general criticisms of the Enlightenment ideal of rationality, offered by Feminist, Multiculturalist, and Postmodemist scholars. If these criticisms are cogent, then both argumentation theory and the view that the aim of education is the fostering of rationality are threatened. I will argue that the criticisms, while important and instructive, are not so destructive of the ideal of rationality as some contemporary scholars suppose. (shrink)

Is there a unique way to de-idealize models? If not, how might the possible ways of reducing the distortion between models and reality differ from each other? Based on an empirical case study conducted in financial markets, this paper discusses how a popular valuation model (the Discounted Cash Flow model) idealizes reality and how the market participants de-idealize it in concrete market situations. In contrast to Cartwright's view that economic models are generally over-constrained, this paper suggests that valuation (...) models are under-constrained. This serves as the reason why the relaxation of simplifying assumptions and concretization do not work as methods of de-idealization. The paper finds that financial market participants de-idealize models using commentary that takes the form of judgment. As a conclusion, a hypothesis is formulated that proposes that the more underdetermined the model is the bigger role narrative and other pragmatic elements play in the process of model application.

This contribution sheds light on the role of infinite idealization in structural analysis, by exploring how infinite elements and finite element methods are combined in civil engineering models. This combination, I claim, should be read in terms of a ‘complementarity function’ through which the representational ideal of completeness is reached in engineering model-building. Taking a cue from Weisberg’s definition of multiple-model idealization, I highlight how infinite idealizations are primarily meant to contribute to the prediction of structural behavior in Multiphysics approaches.

Why does reason matter, if in the end everything comes down to blind faith or gut instinct? Why not just go with what you believe even if it contradicts the evidence? Why bother with rational explanation when name-calling, manipulation, and force are so much more effective in our current cultural and political landscape? Michael Lynch's In Praise of Reason offers a spirited defense of reason and rationality in an era of widespread skepticism--when, for example, people reject scientific evidence about such (...) matters as evolution, climate change, and vaccines when it doesn't jibe with their beliefs and opinions. In recent years, skepticism about the practical value of reason has emerged even within the scientific academy. Many philosophers and psychologists claim that the reasons we give for our most deeply held views are often little more than rationalizations of our prior convictions. _In_ _Praise of Reason_ gives us a counterargument. Although skeptical questions about reason have a deep and interesting history, they can be answered. In particular, appeals to scientific principles of rationality are part of the essential common currency of any civil democratic society. The idea that everything is arbitrary--that reason has no more weight than blind faith--undermines a key principle of a civil society: that we owe our fellow citizens explanations for what we do. Reason matters--not just for the noble ideal of truth, but for the everyday world in which we live. (shrink)

Yet, the existing results don’t settle whether there is a way of approximating coherence that delivers both benefits at (...) once. We show that there is. (shrink)

Why was it that, with belief in the old gods discredited and scepticism spreading widely, Stoic ideals attracted the attention and ultimately won the adhesion of the most thoughtful Romans?Mr. Moellering traces this, first, to Stoicism's appeal to the Roman religious sense, and, secondly, to the Roman character itself. Aeneas, he believes, is the very embodiment of Roman Stoicism.
