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)

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.

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)

: 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 […].

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.

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 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.

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.

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.

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 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.

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.

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)

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 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.
