The concept of feasibility has received a significant amount of scrutiny in recent years. Despite the diversity of accounts, all agree on the assumption that feasibility considerations have a practical function in guiding action. However, the two most important accounts (by Gilabert and Lawford-Smith, and by Wiens) seem to scarcely speak to this practical function because they provide a third-personal reconstruction of feasibility constraints. In this paper, I argue that, to understand feasibility constraints in a way that matters for guiding (...) action, we should switch from a third-personal to an agent-centered perspective. I show that relevant constraints can be Barriers, Limitations, Boundaries, and Rubber Walls to the extent that they concern nomic impossibilities (Barriers), resources (Limitations), agents’ abilities (Boundaries) or other people’s unwillingness (Rubber Walls). Understanding constraints through the lens of their qualitatively different natures opens the way for addressing the problem of how to respond to them. (shrink)

An important theme in recent experimental philosophy is that certain judgements (e.g. our judgements involving intentional action and causation) exhibit a kind of normative penetration whereby, in spite of a not-obviously-normative subject matter, they turn out to be sensitive to, and co-vary with, our normative attitudes in interesting and surprising ways. We present the results of several new experimental studies that suggest that our judgements about feasibility also appear to exhibit this kind of normative penetration in at least some cases; (...) that the best explanation of it involves attributing to subjects a certain kind of extensional error that results from conflating the question at hand with another question that is more salient given their normative attitudes; and that these conclusions have significant, though not straightforward, implications for our understanding of both normative penetration and feasibility, respectively.

Models of idealistic societies pervade the history of political thought from ancient times to the present. How can these models contribute to our thinking about political life in our non-ideal world? Not, as many political theorists have hoped, by performing a normative function -- by giving us reasons to accept particular political principles for the purpose of regulating our thought and behavior. Even still, idealistic models can sharpen our thinking about politics by performing a conceptual function -- by helping us (...) clarify and interpret the concepts we use to describe and evaluate political behavior and institutions. These insights point to a more incisive and judicious approach to political inquiry, in which explanatory and normative modes of thought are tightly intertwined. (The manuscript is under review. I have uploaded the table of contents, chapters 1 and 2, and the bibliography. Chapter summaries are available from my website.). (shrink)

In der vorliegenden Arbeit wird eine normative Analyse und Verteidigung der Erbschaftssteuer unternommen. Zunächst wird eine egalitaristische Argumentation für die Steuer entfaltet. Aufgrund ihrer progressiven Struktur ist die Erbschaftssteuer ein geeignetes Instrument, um der wachsenden ökonomischen Ungleichheit entgegenzuwirken und letztlich verschiedene egalitäre Ideale (politische Gleichheit, Chancengleicheit etc.) zu befördern. Anschließend wird untersucht, wie aus normativer Perspektive zu beurteilen ist, dass der Erblasser bei Erhebung der Steuer nicht mehr lebt. Die restliche Arbeit besteht in einer Auseinandersetzung mit den wichtigsten Einwänden gegen (...) die Erbschaftssteuer. So wird oft behauptet, diese verletze die natürlichen Eigentumsrechte des Erblassers bzw. des Erben und sie ignoriere zudem die Verdienstansprüche des Erblassers. Schließlich sei die Steuer aus diversen "familien-basierten" Erwägungen abzulehnen. Nicht nur werden diese Einwände erfolgreich zurückgewiesen; ferner wird gezeigt, dass einige der, diesen Argumenten zugrundeliegenden, Prinzipien selbst zur Verteidigung einer egalitären Erbschaftssteuer (also einer Erbschaftssteuer, die aus egalitären Prinzipien folgt) herangezogen werden können.

The term “social world” is increasingly familiar in philosophy and political theory. Rawls uses it quite often, especially in his later works. But there has been little explicit discussion of the term and the idea of social worlds. My aim in this paper is to show that political philosophers, Rawlsian or not, should think seriously about social worlds and the roles these things play and ought to play in their work. The idea of social worlds can help political philosophers think (...) about what they do in new and fruitful ways and enrich debates about the roles, aims, and methodology of political philosophy. I begin by analyzing Rawls’s uses of “social world.” I then propose a broadly Rawlsian conception of social worlds as logically possible closed networks of social relations between agents. Next, I put this conception to work, arguing that the idea of navigating the landscape of social worlds can help us better understand the four apparently disparate roles of political philosophy that Rawls presents. Moving beyond Rawls interpretation, I use the idea of social worlds to develop an analogy and distinction between world-oriented and principle-oriented approaches to political philosophy. While principle-oriented approaches grant centrality and importance to engagement with principles of justice, legitimacy, or other political concepts, world-oriented approaches grant centrality and importance to engagement with social worlds. I propose two examples of world-oriented approaches, political philosophy as navigation and political philosophy as world-building, and argue that they are viable and worthy of further consideration.

Faced with political opponents, proponents of climate justice should consider how politically feasible different principles of climate justice are. I focus in this chapter on the political feasibility of an “ability to pay principle” as a proposal for dividing the burdens of past emissions and emissions from the global poor. I argue that a formulation of an ability to pay principle with a voluntarist scope, restricted only to agreed upon collective goals, is significantly more politically feasible than one with a (...) preventative scope, which focuses on preventing a very bad outcome. A voluntarist ability to pay principle can much more clearly be justified to both constrained policy makers and reactionary citizens as a solution to a collective action problem among states that have already bound themselves to collectively solving the problem. A voluntarist principle also has a stronger precedent as a principle of international law. Thus, those philosophers concerned with the political feasibility of an ability-to-pay principle should carefully consider using a voluntarist rather than a preventative formulation. The chapter proceeds as follows. First, I outline what I mean by “political feasibility” and distinguish it from other conceptions of feasibility. Second, I explore the different rationales for a preventative ability to pay principle. Third, I introduce my voluntarist formulation of the ability to pay principle. I then reply to objections to that formulation, arguing that the drawbacks of a voluntarist formulation are not as dire as they might appear. (shrink)

This chapter develops a ``nesting'' model of deontic normative principles (i.e., principles that specify moral constraints upon action) as a means to understanding the notion of a ``fundamental normative principle''. I show that an apparently promising attempt to make sense of this notion such that the ``real'' or ``fundamental'' demands of justice upon action are not constrained by social facts is either self-defeating or relatively unappealing. We should treat fundamental normative principles not as specifying fundamental constraints upon action, but as (...) specifying basic criteria for comparatively evaluating and ranking possibilities.

It is common in political theory and practice to challenge normatively ambitious proposals by saying that their fulfillment is not feasible. But there has been insufficient conceptual exploration of what feasibility is, and very little substantive inquiry into why and how it matters for thinking about social justice. This paper provides one of the first systematic treatments of these issues, and proposes a dynamic approach to the relation between justice and feasibility that illuminates the importance of political imagination and dynamic (...) duties to expand agents’ power to fulfill ambitious principles of justice.

There is a large and growing body of empirical work on people's intuitions about distributive justice. In this paper, we investigate how well luck egalitarianism and desertism--the two normative approaches that appear to cohere well with people's intuitions--are supported by more fine-grained findings in the empirical literature. The time is ripe for a study of this sort, as the positive literature on justice has blossomed over the last three decades. The results of our investigation are surprising. In three different contexts (...) (good option luck, good brute luck, and bad brute luck) in which the demands of luck egalitarianism and those of a mainstream desert-based view come apart, the latter carries the day. One ramification of these findings is that people's intuitions about justice are moralized; that is, they appeal to particular conceptions of the good. Luck egalitarians must decide whether to embrace these moralized intuitions by adopting desertism--or to resist them. (shrink)

: Accusations of infeasibility or utopianism are common in debates over libertarian institutions, but exactly what we mean when we say an idea is “utopian” or “infeasible” is often left unspecified. After reviewing recent philosophical work attempting to clarify the concept of “feasibility,” I consider how the concept has been deployed in the debate among libertarians […].

Climate change goals and actions are often discussed with reference to their feasibility. However, in the climate change literature, there is no agreed upon understanding of what feasibility means. In this paper, insights from political philosophy are used to address this problem in a two-fold way. First, different uses of the term feasibility in the climate change context are critically analyzed, surfacing problematic uses that can have severe consequences for what goals or actions are considered. Second, the ‘conditional probability account (...) of feasibility’ is presented as a positive account of how feasibility should be understood in the climate change context, and applied to the case of managed retreat as an approach for adaptation to sea level rise. Together, the critical analysis and the positive proposal furthers a necessary discussion on feasibility in the context of climate change. (shrink)

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.

Are institutional principles of justice subject to a minimal realism constraint to the effect that, in order to be valid, they must not make wildly unrealistic demands? Most of us say “yes.” David Estlund says, “no.” However, while Estlund holds that 1) institutional principles of justice are not subject to a minimal realism constraint, he accepts that 2) institutional principles of justice are subject to an *attainability constraint* to the effect that, in order to be valid, they must not make (...) demands we are unable to meet; and 3) what he calls “institutional proposals” are subject to a minimal realism constraint. I argue that these three theses do not represent a plausible combination, at least given Estlund’s account of the principle/proposal distinction. Given this account, Estlund is either wrong to reject a minimal realism constraint on institutional principles of justice, or wrong to accept an attainability constraint on institutional principles of justice and/or a minimal realism constraint on institutional proposals. Either way, this has significant implications for the plausibility of his overall case against the minimal realism constraint on institutional principles of justice. (shrink)

It is commonly taken for granted that questions of feasibility are highly relevant to our normative thinking – and perhaps especially our normative thinking about politics. But what exactly does this preoccupation with feasibility amount to, and in what forms if any is it warranted? This article aims to provide a critical introduction to, and clearer characterization of, the feasibility issue. I begin by discussing the question of how feasibility is to be understood. I then turn to the question of (...) feasibility’s role, suggesting that there are two quite different kinds of role questions that may be at play, though they are often run together: a question about feasibility’s normative significance; and a question about its proper use in informing our normative thinking. Finally, I consider how the feasibility issue differs from certain other related issues: the demandingness issue; the issue of whether “ought” implies “can;” and the “ideal versus non-ideal theory” issue.

The familiar complaint that some ambitious proposal is infeasible naturally invites the following response: Once upon a time, the abolition of slavery and the enfranchisement of women seemed infeasible, yet these things were actually achieved. Presumably, then, many of those things that seem infeasible in our own time may well be achieved too and, thus, turn out to have been perfectly feasible after all. The Appeal to History, as we call it, is a bad argument. It is not true that (...) if some desirable state of affairs was actually achieved, then it was feasible that it was achieved. “Actual” does not imply “feasible,” as we put it. Here is our objection. “Feasible” implies “not counterfactually fluky.” But “actual” does not imply “not counterfactually fluky.” So, “actual” does not imply “feasible.” While something like the Flukiness Objection is sometimes hinted at in the context of the related literature on abilities, it has not been developed in any detail, and both premises are inadequately motivated. We offer a novel articulation of the Flukiness Objection that is both more precise and better motivated. Our conclusions have important implications, not only for the admissible use of history in normative argument, but also by potentially circumscribing the normative claims that are applicable to us.

The open borders view is frequently dismissed for making infeasible demands. This is a potent strategy. Unlike normative arguments regarding open borders, which tend to be relatively intractable, the charge of infeasibility is supposed to operate as what we call a "normative argument-stopper." Nonetheless, we argue that the strategy fails. Bringing about open borders is perfectly feasible on the most plausible account of feasibility. We consider and reject what we take to be the only three credible ways to save the (...) charge of infeasibility: by proposing an alternative account of feasibility; by proposing an alternative, more circumscribed interpretation of the subject-matter of feasibility claims; and by proposing a more expansive account of the addressees of the demand for open borders. The first fails to vindicate the claim that infeasibility is a normative argument-stopper. The second does not provide an argument against open borders at all. The third underestimates the power of at least some non-state actors. We conclude by drawing some lessons for the open borders view and the use of feasibility in politics more generally. (shrink)

It is natural and relatively common to suppose that feasibility is a constraint on what we ought to do all-things-considered but not a constraint on what we ought to do as a matter of justice. I show that the combination of these claims entails an implausible picture of the relation between feasibility and desirability given an attractive understanding of the relation between what we ought to do as a matter of justice and what we ought to do all-things-considered.

It is tempting to think (1) that we may sometimes have hopelessly utopian duties and yet (2) that “ought” implies “can.” How might we square these apparently conflicting claims? A simple solution is to interpret hopelessly utopian duties as duties to "pursue" the achievement of manifestly unattainable outcomes (as opposed to duties to "achieve" the outcomes), thereby promising to vindicate the possibility of such duties in a way that is compatible with “ought” implies “can.” The main challenge for this simple (...) solution is to say what the relevant “duties to pursue” are supposed to involve. We survey several existing candidates (duties to try, duties to approximate, duties to do our part, and dynamic duties) and argue that none of them succeeds in delivering on the promise of the simple solution. We then propose a previously untheorized class of duties that we call "duties to devote ourselves" to achieving an outcome, and argue that such duties provide us with an interpretation of hopelessly utopian duties that is up to the task.

Pablo Gilabert and Holly Lawford-Smith have, both in collaboration and individually, provided a compelling account of feasibility, which states that feasibility is both ‘binary’ and ‘scalar’, and both ‘synchronic’ and ‘diachronic’. This two-dimensional analysis, however, has been the subject of four major criticisms: it has been argued that it rests upon a false distinction between ‘hard’ and ‘soft’ constraints, that it ignores the importance of intentional action, and that diachronic feasibility is incoherent and insensitive to the existence of epistemic limitations. (...) In this paper, I will argue that such objections do not undermine the persuasiveness of Gilabert and Lawford-Smith’s analysis. Nevertheless, I will contend that the latter is susceptible to two other challenges. First, it mistakenly appeals to morality, and, second, it lacks an analysis of ability. I will maintain, however, that such criticisms can be addressed and that a revised version of the account should be adopted. (shrink)

The ‘limits of markets’ debate broadly concerns the question of when it is (im)permissible to have a market in some good. Markets can be of tremendous benefit to society, but many have felt that certain goods should not be for sale (e.g., sex, kidneys, bombs). Their sale is argued to be corrupting, exploitative, or to express a form of disrespect. InMarkets without Limits, Jason Brennan and Peter Jaworski have recently argued to the contrary: For any good, as long as it (...) is permissible to give it for free, then it is permissible to give it for money. Their thesis has led to a number of engaging objections, and I leverage recent work on the nature of feasibility within political philosophy to offer a new challenge.I argue that feasibility offers a constraint on which markets can be permissibly implemented. Though it may be possible to create a morally acceptable version of an otherwise repugnant market, some of these markets may be infeasible, and so we are not permitted to implement them. After laying out this challenge, I consider several replies. They concern the relevance of feasibility, and whether any markets really are infeasible. This provides an opportunity to explore the dangers of pursuing the infeasible and with markets generally. I conclude by considering what might lead us to pursue these markets despite their infeasibility, or how knowledge of infeasibility may prove useful regardless. (shrink)

Critics of social injustice argue that the agent of transformative social change will (or should) be a mass agent; namely, an agent that is large, complex, and geographically dispersed. Traditional theories of collective agency emphasize the presence of shared intentions and common knowledge, but mass agents are too large for such cohesion. To make sense of mass agency, I suggest a new approach. On the solidarity theory of mass agency, a mass agent is composed of (a) organizers who intend to (...) fight for social change and (b) supporters who are in solidarity with organizers. (shrink)

The nature of state governance in consolidated liberal democracies has important implications for the ideal theory debate. The states of these societies are polycentric. Decision-making power within them is disaggregated across multiple sites. This rules out one major justification for ideal theory. On this influential view, the ideal furnishes a blueprint of the morally perfect society that we should strive to realise. This justification is not viable in consolidated liberal democracies because their states lack an Archimedean point from which the (...) institutional structure as a whole can be designed to accord with the true ideal – whichever it might be. However, knowledge of the ideal can still aid agents in those societies to determine the worth of more modest political objectives other than the ideal itself. (shrink)

Political philosophy offers a range of utopian proposals, from open borders to global egalitarianism. Some object that these proposals ought to be constrained by what is feasible, while others insist that what justice demands does not depend on what we can bring about. Currently, this debate is mired in disputes over the fundamental nature of justice and the ultimate purpose of political philosophy. I take a different approach, proposing that we should consider which facts could fill out a feasibility requirement. (...) This search for the facts requires requires looking to the social sciences, but I argue that it turns out that the social sciences will not provide us with findings that rule out, nor even count against, the kinds of proposals that political philosophers actually make, whether ideal or non-ideal. At the least, to deny this requires adopting deeply controversial commitments within the philosophy of social science. Thus, I conclude that a feasibility requirement has little practical use for political philosophers. Disputes over that requirement ought to be replaced by other, more fruitful ways for political philosophers to address both the findings of social science and the debates over non-ideal theory or political realism.

Duties to address global injustices face a large motivation gap, particularly amongst those populations most capable of bearing the financial burdens of fulfiling them. This motivation gap is explained, at least in part, by the structure of the state system, which facilitates group identification with fellow citizens to a greater extent than with outsiders. This structural feature of the state system gives states little incentive to further the cause of global justice. Yet, given that states are the most powerful actors (...) on the global stage today, a more just global order is likely predicated upon the development of more just states. In light of these realities, in this paper I make the case for an approach to furthering global justice which i call inward internationalisation. Inward internationalisation calls for the initially modest structural transformation of domestic states, so as to make domestic governments and their constituents increasingly sensitive to their international obligations. Inward internationalisation involves states giving a public, formal, and institutionalised voice within their own domestic deliberations to other states' representatives. This serves informational, expressive, and dynamic functions. After outlining these functions, thereby showing the attraction of inward internationalisation, I argue for the strategic accessibility of inward internationalisation as a path to reform, by outlining the dynamics which might cause inward internationalisation to spread as a norm of governance amongst states.

Many morally significant outcomes can be brought about only if several individuals contribute to them. However, individual contributions to collective outcomes often fail to have morally significant effects on their own. Some have concluded from this that it is permissible to do nothing. What I call ‘the problem of insignificant hands’ is the challenge of determining whether and when people are obligated to contribute. For this to be the case, I argue, the prospect of helping to bring about the outcome (...) has to be good enough. Furthermore, the individual must be in a position to increase the probability of its being brought about to an appropriate extent. Finally, I argue that when too few are willing to contribute, people may have a duty to increase their number. Thus, someone can be obligated to contribute or to get others to contribute. This prospect account is consistent with Kantianism, contractualism and rule consequentialism but inconsistent with act consequentialism. (shrink)

Abstract:Both the idea of feasibility and the role that it might play within political theory are controversial. Recent discussions have attempted to specify an appropriate overall conceptualization of feasibility. This essay offers a more nuanced account of a number of interrelated aspects of feasibility and argues for a more realistic view of feasibility. Four aspects of feasibility are identified and discussed: resource feasibility, value feasibility, human feasibility, and institutional feasibility.

A common objection to a proposal or theory in political philosophy is that it is not feasible to realise what it calls for. This is commonly taken to be sufficient to reject a proposal or theory: feasibility, on this common view, operates as a straightforward constraint on moral and political theory, whatever is not feasible is simply ruled out. This paper seeks to understand what we mean when we say that some proposal or outcome is or is not feasible. It (...) will argue that no single binary definition can be given. Rather, there is a whole range of possible specifications of the term ‘feasible’, each of which selects a range of facts of the world to hold fixed. No single one of these possible specifications, though, is obviously privileged as giving the appropriate understanding of ‘feasibility’ tout court. The upshot of my account of feasibility, then, will be that the common view of feasibility as a straightforward constraint cannot be maintained: in order to reject a moral theory, it will not be sufficient simply to say that it is not feasible.

While methodological and metatheoretical questions pertaining to feasibility have been intensively discussed in the philosophical literature on feasibility and justice in recent years, these discussions have not permeated the debate on global democracy. The overall aim in this paper is to demonstrate the fruitfulness of importing some of the advancements made in this literature into the debate on global democracy as well as to develop aspects that are relevant for explaining the role of feasibility in normative political theory. This is (...) done by pursuing two arguments. First, to advance the work on the role of feasibility, we suggest two metatheoretical constraints on normative political theorizing as intuitively plausible – the ‘fitness constraint’ and the ‘functional constraint’ – which elucidate a number of aspects relevant for determining proper feasibility constraints of an account in political theory. Second, to illustrate the usefulness of this feasibility framework, we sketch an account of global democracy consisting of normative principles which respond differently to these aspects and thus are tied to different feasibility constraints as well as exemplify how it may be applied in practice. (shrink)

Although the discussion about feasibility in political theory is still in its infancy, some important progress has been made in the last years to advance our understanding. In this paper, we intend to make a contribution to this growing literature by investigating the proper place of feasibility considerations in political theory. A motivating force behind this study is a suspicion that many presumptions made about feasibility in several current debates—such as that between practice-independence and practice-dependence, ideal and non-ideal theory, and (...) political moralism and political realism—are too rigid and underestimate the numerous different ways in which feasibility concerns may enter into our theorizing. To chisel out this feasibility space, our aim is to suggest two metatheoretical constraints on normative political principles as intuitively plausible, the so-called ‘fitness constraint’ and the ‘functional constraint’, through which we elucidate five central aspects for determining proper feasibility constraints of an account in political theory. (shrink)

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.

Our world is complex—it is composed of many interacting parts—and this complexity poses a serious difficulty for theorists of social reform. On the one hand, we cannot merely work out ways of ameliorating immediate problems of injustice, because the solutions we generate may interact to set back the achievement of overall long-term justice. On the other, we cannot supplement such problem solving with theorizing about how to make progress towards a long-term goal of ideal justice, because the very interactions that (...) render problem solving unsatisfactory raise insurmountable epistemic difficulties for this latter approach. To accommodate complexity, we must therefore give up on ideal theory, and instead supplement problem solving with a new sort of theorizing that aims to work out how to make our institutional arrangements more progressive: more conducive to further improvements in general, though not necessarily to the achievement of any antecedently specified goal. More concretely, we must identify ways of improving our capacity to flexibly experiment with many promising solutions to problems as they arise, to select for those solutions that prove successful while eliminating those that do not, and to learn from both our successes and our inevitable failures.

The contemporary methodological debate about justice has centered around a dispute about the value of so-called ideal theory. I argue that justice performs a social-guiding function, which explains how people should respond to their limited and fallible abilities to realize justice institutionally. My argument helps to re-orientate the contemporary methodological debate. The obvious disagreement between many prominent supporters and skeptics of ideal theory obscures the fact that they are united by a false assumption: the practical value of justice exclusively consists (...) of its institution-guiding function. To capture the overlooked social-guiding function, a richer normative theory of justice is required; I show how such a theory can be supplied by “ideal-transitional” principles. (shrink)

While there need be no conflict in theory between addressing global inequality (inequalities between people worldwide) and addressing domestic inequality (inequalities between people within a political community), there may be instances in which the feasible mechanism for reducing global inequality risks aggravating domestic inequality. The burgeoning literature on global justice has tended to overlook this type of scenario, and theorists espousing global egalitarianism have consequently not engaged with cases that are important for evaluating and clarifying the content of their theories. (...) This chapter explores potential tensions between promoting global and domestic inequality. We introduce a class of second-best scenarios that global justice theorists have neglected to demonstrate the importance of such scenarios as an aid to constructing and evaluating ideals of global justice.

Debates on the practical relevance of ideal theory revolve around Sen's metaphor of navigating a mountainous landscape. In *The Tyranny of the Ideal*, Gerald Gaus presents the most thorough articulation of this metaphor to date. His detailed exploration yields new insight on central issues in existing debates, as well as a fruitful medium for exploring important limitations on our ability to map the space of social possibilities. Yet Gaus's heavy reliance on the navigation metaphor obscures questions about the reasoning by (...) which ideal theories are justified. As a result, Gaus fails to notice the ways in which his theory of the Open Society resembles the ideal theories he aims to dismiss. Ironically, Gaus winds up neglecting the ways in which the Open Society might tyrannize our efforts to realize greater justice. (This article is part of a symposium on Gaus's *The Tyranny of the Ideal*.). (shrink)
