In 2005, Charles Mills published “‘Ideal Theory’ as Ideology” in Hypatia: a withering critique of much of contemporary political philosophy and ethics. For Mills such work in philosophy failed to attend to the realities of social life and politics, and in remaining silent on actual issues of domination and oppression served an ideological role in supporting the interests of white bourgeois men. Around the time that Charles Mills launched his broadside against ideal theory, trans theorists had (...) been fighting their own battle against the abstraction of theory from the realities of trans lives and oppression. Vivian Namaste (2000) and Jay Prosser (1998) argued that contemporary gender theory failed to justice to the actuality of trans life, retreating instead to understanding trans life through literary archetypes and idealized radical figures. In this chapter I’ll compare Mills’ critique of ideal theory with the transfeminist critique of 1990s gender theory, arguing that they share much in common. Centrally, both critiques share an underlying commitment to theory needing to be grounded in the actuality of oppression and power relations. This common thread, I suggest, must continue to guide transfeminist thought and action: contra Marquis Bey (2022) transfeminist thought and praxis must continue to be about trans lives, about the oppression of trans women, and about ways of actually achieving liberation from our current dire position.

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the (...) three premises she releases ideal theorists from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

This paper articulates and responds to a challenge to contemporary compatibilist views of free will. Despite the popularity and appeal of compatibilist theories, many are left with lingering doubts about compatibilism. This paper explains this doubt in terms of the absurdity challenge: because a compatibilist accepts that they do not have causal access to all the actual sufficient causal sources of their own agency, the compatibilist can find their own agency absurd. By taking a cue from political philosophy, this paper (...) argues that a non-ideal construction of the problem of free will allows compatibilists to overcome this existential-metaphysical challenge, and by doing so, perhaps adopt a metaphysically progressive picture of human agency.

Ideal theory in social and political philosophy generally works to hide philosophical theories’ complicity in sustaining the structural violence and maintenance of white supremacy that are foundational to settler colonial societies. While non-ideal theory can provide a corrective to some of ideal theory’s intended omissions, it can also work to conceal the same systems of violence that ideal theory does, especially when framed primarily as a response to ideal theory. This (...) article takes a decolonial approach to exploring the limitations of non-ideal theory in its ability to respond to and redress the continuing harms done to Indigenous peoples by settler colonialism, including by outlining non-ideal theory’s relationship to a colonial politics of recognition.

Numerous philosophers allege that the "general theory of second best" (Lipsey and Lancaster, 1956) poses a challenge to the Target View, which asserts that real world reform efforts should aim to establish arrangements that satisfy the constitutive features of ideal just states of affairs. I demonstrate two claims that are relevant in this context. First, I show that the theory of second best fails to present a compelling challenge to the Target View in general. But, second, the (...) theory of second best requires ideal theorists to undertake certain kinds of causal and comparative analyses that are typically thought to lie beyond the borders of conventional ideal theory.

Realist thinkers in political philosophy often criticize ideal theorists for neglecting or eliminating the fact of politics in their work. This is supposed to be problematic because we should never expect to overcome politics. Any theory that attempts to do so is said to be unrealistic, naïve, and impractical. Although much has been said in the dispute between realists and ideal theorists in recent years, this particular line of criticism, which should be distinguished from other criticisms of (...) ideal theory, has not been clearly or explicitly addressed by ideal theorists in the literature. I deal with this issue by examining the ideal theory of John Rawls, which has been a prominent target of realist criticisms. My aim is to see where politics exists, or might exist, in Rawls’s theory, and whether this politics satisfactorily answers to the various aspects of the realist’s critique. My analysis suggests that there may be no inherent or necessary conflict between ideal theory and real politics, after all. (shrink)

When we can’t live up to the ultimate standards of morality, how can moral theory give us guidance? We can distinguish between ideal and non-ideal theory to see that there are different versions of the voluntarist constraint, ‘ought implies can.’ Ideal moral theory identifies the best standard, so its demands are constrained by one version. Non-ideal theory tells us what to do given our psychological and motivational shortcomings and so is constrained by (...) others. Moral theory can now both provide an ultimate standard and give us guidance; this view also gives us new insights into demandingness and blame. (shrink)

The two main questions addressed in the chapter are “What is the point of (good) nonideal theory?” and “Can (good) nonideal theory be done in isolation from ideal theory?” To address them, I distinguish between different types of nonideal theory and locate nonideal theory vis‐à‐vis ideal theory as well as realism and applied philosophy. I argue that nonideal theory is useful but some of its versions need to concede that they are (...) defeatist. I also argue that nonideal theory builds on ideal theory, though not in all the ways suggested by defenders of ideal theory. (shrink)

What is the best way to make sustained societal progress over time? Non-ideal theory done on its own faces the problem of second best, but ideal theory seems unable to cope with disagreement about how to make progress. If ideal theory gives up its claims to completeness, then we can use the method of incompletely theorized agreements to make progress over time.

The growth of non-ideal theory and of political realism has had a profound influence on methodological inquiry in political philosophy. It is now the norm for authors defending ideal theory to take special care to show that it can relate to the real world in the right sort of way. Two recent books—David Estlund’s Utopophobia: On the Limits (If Any) of Political Philosophy ( 2020 ), and Ben Laurence’s Agents of Change: Political Philosophy in Practice ( (...) 2021 )—fit this mold. Both authors argue that ideal theory can be practical, and Estlund additionally argues that it can be valuable even if it lacks practical value. In this commentary, I argue that something important is missing from these defenses of ideal theory: they both fail to be realistic in a “second-order” way. I suggest that other recent work comes closer to meeting this standard. (shrink)

This paper centers two complementary theoretical approaches to advance the debate about transgender women’s inclusion in elite women’s sports – namely, non-ideal theory and cultural studies. In doing so, the paper highlights divisions between ideal theory and non-ideal theory, normative internalism in sports and normative externalism in sports, and essentialist views of sports compared to non-essentialist views of sports. The paper’s main agenda is to show the value of applying non-ideal theory, externalism, (...) and non-essentialism to the discourse over transgender inclusion. (shrink)

Rawls’s contractualist approach to justice is well known for its adoption of ideal theory. This approach starts by setting out the political goal or ideal and leaves it to non-ideal or partial compliance theory to map out how to get there. However, Rawls’s use of ideal theory has been criticized by Sen from the right and by Mouffe from the left. We critically address these concerns in the context of developing a Rawlsian approach (...) to climate justice. While the importance of non-ideal theory for climate justice is increasingly being understood, its strategic and institutional importance for a Rawlsian approach needs further elaboration. We focus on the role of the Kantian conception of the reasonable and rational powers of persons in Rawls’s work and show how this helps us to develop a partial compliance theory that focuses on the importance of institutions and strategic political action for achieving climate justice.

In considering what makes epistemic injustice and epistemologies of ignorance wrongful, Matthew Congdon has recently argued that they involve forms of epistemic misrecognition in involving epistemic disrespect, disesteem, and neglect. Following Congdon’s remarks that both epistemic injustice and epistemologies of ignorance involve such misrecognition, this chapter considers whether and how ignorance may not involve the same types of misrecognition as epistemic injustice. In fact, there may be, as of yet, unexplored and surprising ways in which ignorance and recognition work in (...) concert. In this chapter, I contend that some cases of genuine ignorance do not involve misrecognition, but a kind of recognition: sometimes ignorance is not about being insufficiently responsive to some normatively relevant features in another, but being too responsive to them. I then argue that we can see this sort of ‘paradox of ignorance’ in Charles Mills’s discussion of white ignorance and ideal theory. (shrink)

The debate on ideal theory focuses mainly on whether it can provide a long-term target and a metric for assessing the justice of different institutional arrangements in non-ideal theory. Both critics and defenders of ideal theory typically overlook the role it plays in a model of fairness that can restrict the range of permissible arrangements under non-ideal conditions. In this paper, I explain ideal theory’s fairness role and its part in ensuring (...) an institutional structure that benefits everyone in a society. Critics of ideal theory therefore cannot reject it as simply useless. But I consider how they can question the attractiveness of an ideal-theory-based fairness constraint on non-ideal theory.

It is conventional wisdom among political philosophers that ideal principles of justice must guide our attempts to design institutions to avert actual injustice. Call this the ideal guidance approach. I argue that this view is misguided— ideal principles of justice are not appropriate "guiding principles" that actual institutions must aim to realize, even if only approximately. Fortunately, the conventional wisdom is also avoidable. In this paper, I develop an alternative approach to institutional design, which I call institutional (...) failure analysis. The basic intuition of this approach is that our moral assessment of institutional proposals is most effective when we proceed from a detailed understanding of the causal processes generating problematic social outcomes. Failure analysis takes the institutional primary design task to be obviating or averting institutional failures. Consequently, failure analysis enables theorists to prescribe more effective solutions to actual injustice because its focuses on understanding the injustice, rather than specifying an ideal of justice.

Two types of idealization in theory construction are distinguished, and the distinction is used to give a critique of Ron Laymon's account of confirming idealized theories and his argument for scientific realism.

In Against Purity, Alexis Shotwell takes up a multiplicity of tasks with respect to what I think of as non-ideal ethical theory. In what follows, I trace the relationship of her work to that of non-ideal theorists whose work influences mine. Then, more critically, I probe her analysis of gender voluntarism in Chapter 5, “Practicing Freedom: Disability and Gender Transformation,” partly to better understand what she takes it to be, and partly to advance a cautious defense of (...) some of the moral functions of individualistic performances of gender voluntarism that non-ideal theory leads me to value. I conclude that my interest in retaining a positive account of individualistic gender voluntarism as a form of resistance to a hostile world is due to my tendency to take non-ideal theory as a recommendation for some pessimism, whereas Shotwell’s similar commitments turn out to inform her more optimistic philosophy.

One of the most troubling features of international trade is that it often involves exchange between individuals facing dramatically different life circumstances, who therefore derive different levels of benefit from the exchange. Most obviously, wages are extremely low in underdeveloped countries. However, the principle underlying these wages is the same as the one the dictates wage levels in wealthy countries. It is, therefore, difficult to criticize the wages paid to ?pauper labor? without at the same time criticizing the way that (...) capitalism functions as a whole. For those who would like to question aspects of globalization, without simply repeating the standard moralizing critique of capitalism, this poses particular difficulties. This paper offers some suggestions on how egalitarians can approach this issue. The central piece of conceptual apparatus introduced, in the service of this aim, is the distinction between a ?first-best?, a ?second-best?, and an ?nth best? set of normative principles. It is then suggested, first, that capitalism is acceptable to egalitarians only within a third-best framework, and second, that this low level of idealization imposes real constraints on how far one can go in criticizing trade practices at the global level.

The modern social world is unjust. It is also complex. What does this latter fact imply about the kind of approach that should be used in ameliorating the injustice expressed in the former fact? One answer, recently put forth by Jacob Barrett, is that _ideal theory_, which he understands as being fundamentally defined by the identification and subsequent pursuit of an aspirational macro-level institutional goal, lacks a place in social reform. The reason he thinks ideal theory lacks a (...) place has to do with its inability to deal with complexity. _Pace_ Barrett, I argue that ideal theory, suitably understood, can play a valuable role in social reform in a complex world. While some ideal theorists have underappreciated the extent to which complexity considerations complicate social reform, this does not mean that there is no place for it. This paper surveys the resources ideal theory has available to cope with what I call _the challenge of complexity_. Although the coping techniques will be successful to varying degrees, I believe, in aggregate, a compelling case can be made that ideal theory can combat the challenge of complexity. Still, one may worry that even if ideal theory can adequately deal with complexity, it cannot adequately deal with ever-changing social circumstances. Call this _the dancing landscape objection_. A static ideal theory cannot overcome it, but a _dynamic ideal theory_ could. In sum, dynamic ideal theory can contribute to social reform in a complex and mutable social world. (shrink)

This paper discusses non-ideal theory as guidance for making bad situations better by morally permissible means. It distinguishes constructive theorizing, which suggests ways of improving specific kinds of bad situation, from cautionary theory, which concerns moral risks of actions under bad conditions. Reflective moral judgment yields cautionary precepts, identifying presumptively unjustifiable modes of action. The paper illustrates the application of precepts cautioning about coercion and the exposure of others to significant risks, by considering the 1955–1956 bus boycott (...) in Montgomery, Alabama, and the ‘Children’s Crusade’ of the 1963 Birmingham desegregation campaign. All such campaigns involve coercive elements, but the paper argues that coercion was not a morally significant factor in either case. Endangerment is another matter: given the violent, sometimes lethal, reactions to civil rights actions under Jim Crow, those two campaigns’ endangerment of innocent persons must be taken very seriously, especially as it concerns Birmingham. And, in fact, potentially lethal anti-reform violence occurred during each campaign. Relevant factors include the preparation and understanding of young participants and the difference in risk that is assumed by engaging in peaceful, nonviolent public actions. (shrink)

Journal of Social Philosophy, EarlyView.

This article clarifies the disagreement concerning ideal theory’s action-guiding capacity through the unpacking of two underlying disagreements. The first concerns the threshold for action-guidance on the scales of empirical and normative determinacy; I argue that the dispute between critics and proponents of ideal theory is not about whether ideal principles offer some specific information, but about which information should count as action-guiding. The second concerns the task of normative principles; I argue that the different weight (...) critics and proponents attribute to the risks associated with ideal theory may reflect diverging views on whether principles primarily generate or explain normative judgments.

Abstract: Philosophers who have addressed the problems of enduring racial injustice have been suspicious of the role played by ideal theory in ethics and political philosophy generally, and in contemporary liberal political philosophy in particular. The theoretical marginalization of race in the work of Rawls has led some to charge that ideal theory is at the very least unhelpful in understanding one of the most significant forms of contemporary injustice, and is at worst ideological in the (...) pejorative sense. To explore these concerns, I formulate five related criticisms of ideal theory and examine each as it would be applied to Rawls's political philosophy. My thesis is that the strongest criticisms—namely, that ideal theory is essentially ideological and cannot provide adequate grounds for justifying race-conscious, equality-securing measures—ultimately miss the mark. But other criticisms of ideal theory are more plausible, and most plausibly directed to an area of Rawls's thought often ignored in discussions of liberalism and race, namely, his account of citizenship and public reasoning.

This paper examines what agents should do when others fail to comply with their responsibilities to prevent dangerous climate change. It distinguishes between six different possible responses to noncompliance. These include what I term (1) 'target modification' (watering down the extent to which we seek to prevent climate change), (2) ‘responsibility reallocation’ (reassigning responsibilities to other duty bearers), (3) ‘burden shifting I’ (allowing duty bearers to implement policies which impose unjust burdens on others, (4) 'burden shifting II’ (allowing some to (...) protect peoples rights in ways which impose otherwise unjustified burdens on the duty bearers, (5) 'compromising moral ideals' (permitting agents to compromise non-justice ideals that they are otherwise bound by); and (6) ‘promoting compliance (implementing policies and creating institutions which reduce noncompliance). It concludes by outlining a methodological framework for evaluating these options, and by setting out my tentative and provisional evaluation of which responses are the least bad. (shrink)

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an (...) application of a particular branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

Mit seiner Unterscheidung zwischen idealer und nicht-idealer Theorie hat John Rawls eine der zentralen Methodendiskussionen der gegenwärtigen politischen Philosophie angestoßen (vgl. Simmons 2010; Valentini 2012). An dieser Alternative entzündete sich später auch grundlegende Kritik an Rawls’ Werk. Die Unterscheidung wird in Eine Theorie der Gerechtigkeit eingeführt (Rawls 1971, 9), um die Zielsetzung und die Grenzen von Rawls’ Theorieansatz zu bestimmen.

Political philosophers have recently begun to take seriously methodological questions concerning what a theoretical examination of political ideals is suppose to accomplish and how effective theorising in ideal theory is in securing those aims. Andrew Mason and G.A. Cohen, for example, believe that the fundamental principles of justice are logically independent of issues of feasibility and questions about human nature. Their position contrasts sharply with political theorists like John Dunn and Joseph Carens who believe that normative theorising must (...) be integrated with an appreciation of the empirical realities of one’s society. Rather than bracket questions of feasibility and human nature, empirically-oriented political theorists believe that real, non- ideal considerations must be taken seriously when deriving normative theories of justice.1 And some justice-theorists, most notably John Rawls, attempt to.

Some realists in political theory deny that the notion of feasibility has any place in realist theory, while others claim that feasibility constraints are essential elements of realist normative theorising. But none have so far clarified what exactly they are referring to when thinking of feasibility and political realism together. In this article, we develop a conception of the realist feasibility frontier based on an appraisal of how political realism should be distinguished from non-ideal theories. In this (...) realist framework, political standards are feasible if they meet three requirements: they are politically intelligible, contextually recognisable as authoritative, and contestable. We conclude by suggesting that our conception of realist feasibility might be compatible with utopian demands, thereby possibly finding favour with realists who otherwise refuse to resort to the notion of feasibility.

This chapter delineates two types of ideal theory that are found in Rawls’s corpus of work. The first is ideal-method theory, which is theory constructed using idealizing assumptions that do not directly correspond with the actual world. The second is ideal-content theory, namely criteria for assessing whether something is a perfectly justice institution. The chapter provides an independent justification for both types of theory, arguing that ideal-method theory is valuable within (...) certain parameters; for instance, the idealizing assumption of strict compliance helps to clarify the distinction between distributive and retributive justice. The chapter illuminates the value of ideal-content theory by clarifying and defending Rawls’s claim that nonideal theory depends on ideal-content theory. In particular, it argues that in order to gain a systematic grasp of the more pressing problems of nonideal theory it is plausible to argue that ideal-content theory is necessary. -/- . (shrink)

Our societies are marked by anthropocentrism: most people treat animals in ways in which they would by no means treat fellow humans. One might nonetheless expect this prejudice to be much less prevalent in animal shelters since these places are created for the very sake of non-humans and generally managed by people who truly care about animal welfare. This chapter questions this expectation. It discusses three practices that are widespread in animal shelters and yet could be suspected of anthropocentrism: killing (...) animals for lack of resources, partnering with the livestock industry, and feeding animals meat. Drawing on the distinction between ideal and non-ideal theory, the chapter argues that management euthanasia and cooperation with animal agriculture are acceptable in non-ideal theory even though they would be condemned by ideal theory. Then it argues that meat-based pet food should be rejected even in the non-ideal circumstances faced by animal shelters. (shrink)

This article provides a conceptual map of the debate on ideal and non‐ideal theory. It argues that this debate encompasses a number of different questions, which have not been kept sufficiently separate in the literature. In particular, the article distinguishes between the following three interpretations of the ‘ideal vs. non‐ideal theory’ contrast: (i) full compliance vs. partial compliance theory; (ii) utopian vs. realistic theory; (iii) end‐state vs. transitional theory. The article advances (...) critical reflections on each of these sub‐debates, and highlights areas for future research in the field. (shrink)

Rawlsian ideal theory is meant to perform various roles in non-ideal theory. In this paper, I distinguish between three roles, and I consider the extent to which we can expect ideal theory to perform them. It is meant to serve as a target to guide non-ideal theorising in the long-term. It is also supposed to provide a way of comparing different injustices to tell us which is worst and therefore in most urgent need (...) of a remedy. Finally, ideal theory is the basis for a model of fairness that restricts the set of morally permissible measures in non-ideal theory. I show how the first two roles—the target and urgency roles—are less plausible than the fairness role. (shrink)

This paper has three aims. First, it argues that the present use of ‘ideal theory’ is unhelpful, and that an earlier and apparently more natural use focusing on perfection would be preferable. Second, it has tried to show that revision of the use of the term would better expose two distinctive normative issues, and illustrated that claim by showing how some contributors to debates about ideal theory have gone wrong partly through not distinguishing them. Third, in (...) exposing those two distinct normative issues, it has revealed a particular way in which ideal theory even under the more specific, revisionary definition will often be central to working out what to do in non-ideal circumstances. By clarifying the terms on which debates over ideal and non-ideal theory should take place, and highlighting the particular problems each deals with, it tries to clear the ground for turning to the actual problem, which is what to do in our non-ideal and often tragic circumstances.

Critical attention directed to John Rawls ’s ideal theory has in particular leveled three charges against it: first, its infeasibility; second, its inadequacy for providing normative guidance on actual injustices; and third, its insensitivity to the justice concerns of marginalized groups. Recently, advocates for Rawls ’s ideal theory have replied that problems arising at the stage of ideal theory can be addressed at the later stage of his nonideal theory. This article disputes that (...) claim by arguing that although Rawls ’s nonideal theory provides a good answer to the infeasibility charge, it does not do so for the second and third charges. To argue for this thesis, I illustrate that nonideal theory in Rawls ’s Law of Peoples is unable to identify crucial injustices that emerge in the nonideal conditions of real world globalization.

An intensified discussion on the role of normative ideals has re-emerged in several debates in political philosophy. What is often referred to as “ideal theory,” represented by liberal egalitarians such as John Rawls, is under attack from those that stress that political philosophy at large should take much more seriously the nonideal circumstances consisting of relations of domination and power under which normative ideals, principles, and ideas are supposed to be applied. While the debate so far has mainly (...) been preoccupied with defending or rejecting ideal theory through a defense or rejection of a specific ideal theory, this paper instead focuses on a number of general philosophical concerns on which the critique relies. More specifically, it brings up for scrutiny, and ultimately rejects, three charges against ideal theory: the charge that ideal theory is not action-guiding, that ideal theory is impossible, and that ideal theory is distorting. By investigatingthese charges in tandem, the paper shows that the criticism against ideal theory is premised on assumptions about the relationships between thought and action and between concepts and the world for which there is little or no support.

This article analyses a hitherto neglected problem at the transition from ideal to non‐ideal theory: the problem of knowledge. Ideal theories often make idealising assumptions about the availability of knowledge, for example knowledge of social scientific facts. This can lead to problems when this knowledge turns out not to be available at the non‐ideal level. Knowledge can be unavailable in a number of ways: in principle, for practical reasons, or because there are normative reasons not (...) to use it. This can make it necessary to revise ideal theories, because the principle of ‘ought implies can’ rules out certain theories, at least insofar as they are understood as action‐guiding. I discuss a number of examples and argue that there are two tendencies that will increase the relevance of this problem in the future: the availability of large amounts of sensitive data whose use is problematic from a normative point of view, and the increasing complexity of an interrelated world that makes it harder to predict the effects of institutional changes. To address these issues, philosophers need to cooperate with social scientists and philosophers of the social sciences. Normative theorising can then be understood as one step in a long process that includes thinkers from different disciplines. Ideal theory can respond to many of the charges raised against it if it is understood along these lines and if it takes the problem of knowledge and its implications seriously. (shrink)

Political philosophers working on ideal and non-ideal theory sometimes seem to be stuck in a bind: while ideal theory risks being too ideal to be useful in the real world, non-ideal theory risks being so non-ideal that it stops far short of justice. In this paper, I highlight a third – and equally unappealing – possibility: that non-ideal theory, precisely because of its obvious engagement with real-world problems, might fail (...) to recognize the unacceptable ways in which it is itself problematically idealized. I highlight this problem through the case-study of adaptive preferences. Although work in adaptive preferences obviously fits into non-ideal theory, the actual work being done in the literature is idealized in that it takes only the circumstances and needs of adults into account. In the best case, this means that the needs of one of our most vulnerable populations – that is, children – are ignored. In the worst case, where the needs of children and adults conflict, the needs of children will be actively frustrated. In this way, non-ideal theory can fail to approximate justice precisely because it fails to recognize the idealizations that it itself employs. (shrink)
