Moral Contractarianism

Gauthier’s contractarianism begins with an idea of a rational deliberator but ‘finds no basis for postulating a moral need for the justification of one’s actions to others. The role of agreement is to address each person’s demand that the constraints of society be justified to him, not a concern that he justify himself to his fellows’ (Gauther 1997, 134–5). He contrasts his view with Scanlon’s contractualism, according to which agreement with others is the core of morality and each agent has (...) the burden of justifying his or her actions to others. Both of their views count as ‘constructivist’ because they reject moral realism and hold that normativity is a function of what we do, either individually or collectively. Kant’s Rechtslehre is neutral regarding moral realism and yet constructivist about moral norms. However, the relevant acts basic to Gauthier’s and Scanlon’s views concern voluntary agreements we make. Using agreement to establish basic norms faces some serious difficulties. Kant’s Rechtslehre avoids these problems by showing how basic social norms can be identified and justified independently of voluntary agreement. Moreover, it does so in a way that shows that an individual’s justification of his or her acts to others and the justification of the acts of others to any individual are inseparable aspects of one and the same justificatory reasons in which voluntary agreement plays no role.

Contemporary moral contractarianism originates with Hobbes’s moral theory. When considering the structure of Hobbes’s moral theory, however, it is often argued that moral contractarianism does not justify any specific moral demands concerning questions of climate change because currently no global Leviathan in Hobbes’s sense exists that could enforce any such demands in our world. I do not dispute the fact that currently no global Leviathan in Hobbes’s sense exists in our world. Nevertheless, I argue that Hobbesian moral contractarianism offers an (...) adequate moral framework to guide our considerations concerning questions of climate change. Methodologically, the approach is sufficiently pluralistic to consider ethical and economic considerations as well as political feasibility constraints. Conceptually, I argue that, despite the fact that currently no global Leviathan in Hobbes’s sense exists in our world, a Hobbesian-inspired modus vivendi is sufficient as a starting point to address some of the most pressing issues of climate change in our world. Specifically, I argue that the shift in climate change negotiations from the Kyoto Protocol to the Paris Agreement could be considered to be guided by reasoning that underlies Hobbesian moral contractarianism.

The history of contractarian moral theory is long and varied. It includes the classic social contract theories of Hobbes (1651), Hume (1739/1740), and Kant (1785) as well as modern versions of these theories, such as those of Gauthier (1986), Scanlon (1998), Darwall (2006), and Southwood (2010). In Minimal Morality: A Multilevel Social Contract Theory (2018), I continue this tradition by developing a ‘multilevel social contract theory’ that combines Humean, Hobbesian, and Kantian moral features. In this article, I reply to comments (...) by Fred D’Agostino, John Thrasher, Christopher W. Morris, and Peter Vanderschraaf. I am deeply grateful for these commentators’ constructive and engaging comments that, in their own way, shed light on core assumptions and features of the theory. Due to space restrictions, I focus on what I consider to be the main criticisms and have organized my responses thematically. I hope that doing so will also help readers who are less familiar with my work to understand the relevance of multilevel social contract theory for morally diverse societies. (shrink)

This book provides a systematic defense of moral contractarianism as a distinct approach to the social contract. It elucidates, in comparison to moral conventionalism and moral contractualism, the distinct features of moral contractarianism, its scope, and conceptual and practical challenges that concern the relationship between morality and self-interest, the problems of assurance and compliance, rule-following, counterfactualism, and the nexus between morals and politics. It argues that, if appropriately conceived, moral contractarianism is conceptually coherent, empirically sound, and practically relevant, and has (...) much to offer to contemporary moral philosophy.

In Minimal Morality, Michael Moehler justifies what he calls the weak principle of universalization as a principle of pure instrumental morality. This article addresses the application of this principle and problems associated with it. Specifically, the article focuses on the principle’s ability to protect the interests of the most vulnerable members of society: agents without primary moral standing, specifically non-human animals; and the weakest members of society, either as a result of their diminished relative bargaining power in certain cases of (...) conflict, or because of their present standing in society, made worse off by historical injustices. To this end, the article considers, respectively, the problems of moral standing, indivisible goods and historical injustice. (shrink)

When Buchanan discusses the constitutional changes that members of society would agree to, he uses the status quo as the default. If no agreement occurs, we continue with the constitutional rules that are currently in place. This article argues that this choice results in an unjustified status quo bias. To make this point, I examine and challenge three possible arguments in favor of using the status quo as the default. Then, I give two arguments in favor of a form of (...) contractarianism that does not use the status quo as a default. (shrink)

Abstract. In Minimal Morality (2018), I develop a multilevel social contract theory that accommodates deep moral pluralism. In this article, I reply to comments by Gaus, Van Schoelandt and Cooper concerning the three core projects of the book that aim to (i) revive orthodox rational choice contractarianism as a viable approach to the social contract, (ii) integrate this approach into a comprehensive social contract theory and (iii) show the applicability of the theory to the real world. My replies clarify some (...) of the main features of the theory, defend its core projects and expand discussion of some of its details in order to show that the theory can address the challenges raised. (shrink)

In Minimal Morality, I develop a multilevel social contract theory that, in contrast to existing theories in the liberal tradition, does not merely assume a restricted form of reasonable moral pluralism, but is tailored to the conditions of deeply morally pluralistic societies that may include liberal moral agents, nonliberal moral agents, and, according to the traditional understanding of morality, nonmoral agents. The theory takes its main inspiration from the moral theories of Hobbes (1651), Hume (1739/1740), and Kant (1785, 1795, and (...) 1797), and some of their contemporary followers, such as Rawls (1971) and Gauthier (1986). In its simplified form, the theory combines what I call traditional first-level morality with second-level pure instrumental morality and derives, in the form of the weak principle of universalization, a principle of conflict resolution that defines the minimal behavioral restrictions that are necessary to ensure, compared to violent conflict resolution, mutually beneficial peaceful long-term cooperation in deeply morally pluralistic societies. I argue that, despite its ideal nature, this theory is, in principle, applicable to the real world and, for the conditions described, most promising for securing mutually beneficial peaceful long-term cooperation in a world in which a fully just society, due to moral pluralism, is unattainable.

The topic of moral diversity is not only prevalent in contemporary moral and political philosophy, it is also practically relevant. Moral diversity, however, poses a significant challenge for moral theory building. John Thrasher, in his discussion of public reason theory, which includes social contract theory, argues that if one seriously considers the goal of moral constructivism and considerations of representation and stability, then moral diversity poses an insurmountable problem for most public reason theories. I agree with Thrasher that moral diversity (...) poses a significant challenge for orthodox multistage social contract theories. In fact, I even add a further problem for such theories under the assumption of deep moral diversity. Nevertheless, I argue that my recently developed multilevel social contract theory overcomes these problems. I focus on some of the underexplored features of this theory to show that multilevel social contract theory offers one conceptually coherent and plausible way to render social contract theory viable and relevant for modern diverse societies.

How should contractualists seek to accommodate and respond to the existence of radical pluralism within contemporary liberal states? Ryan Muldoon has recently argued that a) the dominant Kantian liberal model of contractualism is hopelessly ill equipped to do so but that b) there is a particular kind of Hobbesian contractualism that can do much better. I raise some problems concerning the capacity of Muldoonian contractualism to respond appropriately to the problem of radical pluralism. I then propose a very different kind (...) of solution that involves embracing an advice model of contractualism. Keywords: contractualism; contractarianism; pluralism; diversity; disagreement .

A difficult problem for contractualists is how to provide an interpretation of the contractual situation that is both subject to appropriately stringent constraints and yet also appropriately sensitive to certain features of us as we actually are. My suggestion is that we should embrace a model of contractualism that is structurally analogous to the “advice model” of the ideal observer theory famously proposed by Michael Smith (1994; 1995). An advice model of contractualism is appealing since it promises to deliver a (...) straightforward solution to the so-called “conditional fallacy.” But it faces some formidable challenges. On the face of it, it seems to be straightforwardly conceptually incoherent. And it seems to deliver a solution to the conditional fallacy at the cost of being vulnerable to what I shall call “the concessional fallacy.” I shall consider how, if at all, these challenges are to be met. I shall then conclude by considering what this might mean for the so-called “ideal/non-ideal theory” issue. (shrink)

Trust is so intimately linked with faith that sometimes trust needs faith to unfold in a relationship. I argue that the role of this faith element in trust is to elevate the status of the one in which we trust so as to emphasize the equal dignity of all the participants in the relationship of trust. Against views that focus on a «rational» trust based on an exaggerated emphasis on the capacity of self-trust as a point of departure for the (...) trust in others, the essay develops toward the depiction of a kind of trust that is rooted in faith and still maintains a «reasonable» character. By way of discussing the implications of Thomas Hobbes’s reflections on covenants and contracts, and Annette Baier’s critique of what she sees as the Hobbesian «fixation» on contracts, I argue toward the identification of what I call a «covenantal trust» in contemporary political ontology.

What are we required to do? Who are we required to be? And why are we required to do these things or be these types of people? Ethical theories attempt to systematically answer these questions. This essay examines the most prominent such theories, evaluating each for their strengths and weaknesses.

The prospective introduction of autonomous cars into public traffic raises the question of how such systems should behave when an accident is inevitable. Due to concerns with self-interest and liberal legitimacy that have become paramount in the emerging debate, a contractarian framework seems to provide a particularly attractive means of approaching this problem. We examine one such attempt, which derives a harm minimisation rule from the assumptions of rational self-interest and ignorance of one’s position in a future accident. We contend, (...) however, that both contractarian approaches and harm minimisation standards are flawed, due to a failure to account for the fundamental difference between those ‘involved’ and ‘uninvolved’ in an impending crash. Drawing from classical works on the trolley problem, we show how this notion can be substantiated by reference to either the distinction between negative and positive rights, or to differences in people’s claims. By supplementing harm minimisation with corresponding constraints, we can develop crash algorithms for autonomous cars which are both ethically adequate and promise to overcome certain significant practical barriers to implementation.

Traditional rule consequentialism faces a problem sometimes called the ideal world objection—the worry that by looking only at the consequences in worlds where rules are universally adhered to, the theory fails to account for problems that arise because adherence to rules in the real world is inevitably imperfect. In response, recent theorists have defended sophisticated versions of rule consequentialism which are sensitive to the consequences in worlds with less utopian levels of adherence. In this paper, I argue that these attempts (...) underestimate the problem they are designed to avoid—the worry about ideal worlds is only one manifestation of a deeper and more general problem, the distant world objection, which threatens not only the sophisticated revisions of rule consequentialism, but any view which determines what we ought to do by evaluating worlds that differ from ours in more than what is up to us.

Peter Stemmer has developed an elegant and impressive theory of normativity and morality. In this article, I try to show that he does not achieve two goals he set for himself. First, his theory does not capture the categorical bindingness of moral demands, even in Stemmer’s own interpretation of categorical bindingness: it does not show that we must follow moral demands no matter what our personal goals and desires are. Second, just because it would be rational to establish positive moralities (...) in a hypothetical pre-moral scenario, it does not follow – and Stemmer does not establish – that only positive moralities that are in the interest of all members are legitimate. For that reason, his contractarian theory collapses into relativism. (shrink)

In a 2013 article, David Gauthier noted upon the twenty-fifth anniversary of the publication of Morals by Agreement that his contractarian approach to morality had found a niche among ‘some of those who remain unpersuaded by either Kantianism or utilitarianism’. In this article I will focus on Pareto optimization and I will argue that the Gauthier contract, even in spite of the article’s revisions, is still less useful for consultation purposes than Gauthier is assuming. To highlight the conceptual distance that (...) I think separates the Gauthier contract from real-world circumstances—a separation that is greater than Gauthier supposes—I will focus on the problem of ‘civic defection’. The point is not for us to repudiate as such the deliverances of the Gauthier model, but simply to use caution in our deployment of the model, and, in order to access the full extent of the model’s offerings, to resist the temptation to deploy it in the service of purposes which it is not capable of accomplishing.

Contractarianism is more inclusive than critics (and, indeed, Gauthier) sometimes suggest. Contractarianism can justify equal moral standing for human persons (in some respects) and provide sufficient moral standing for many nonhuman animals to require what we commonly call decent treatment. Moreover, contractarianism may allow that some entities have more moral standing than others do. This does not necessarily license the oppression that liberal egalitarians rightly fear. Instead, it shows that contractarianism may support a nuanced account of moral status.

In a recent article, Gauthier rejects orthodox rational choice contractarianism in favor of a revisionist approach to the social contract that, according to him, justifies his principle of maximin proportionate gain as a principle of distributive justice. I agree with Gauthier that his principle of maximin proportionate gain cannot be justified by orthodox rational choice contractarianism. I argue, however, that orthodox rational choice contractarianism, before and after Gauthier, is still a viable approach to the social contract, although the scope of (...) this approach is limited. Orthodox rational choice contractarianism can be applied fruitfully to moral philosophy only in situations of deep moral pluralism in which moral reasoning is reduced to instrumental reasoning, because the members of society do not share, as assumed by traditional moral theories, a consensus on moral ideals as traditionally conceived as a starting point for the derivation of moral rules but only an overarching end that they aim to reach. If orthodox rational choice contractarianism is applied adequately, then it offers a viable approach to the social contract that, in contrast to Gauthier’s theory, justifies a rival principle for distributive conflicts that is valid for deeply morally pluralistic societies.

Very diverse societies pose real problems for Rawlsian models of public reason. This is for two reasons: first, public reason is unable accommodate diverse perspectives in determining a regulative ideal. Second, regulative ideals are unable to respond to social change. While models based on public reason focus on the justification of principles, this book suggests that we need to orient our normative theories more toward discovery and experimentation. The book develops a unique approach to social contract theory that focuses on (...) diverse perspectives. It offers a new moral stance that author Ryan Muldoon calls, "The View From Everywhere," which allows for substantive, fundamental moral disagreement. This stance is used to develop a bargaining model in which agents can cooperate despite seeing different perspectives. Rather than arguing for an ideal contract or particular principles of justice, Muldoon outlines a procedure for iterated revisions to the rules of a social contract. It expands Mill's conception of experiments in living to help form a foundational principle for social contract theory. By embracing this kind of experimentation, we move away from a conception of justice as an end state, and toward a conception of justice as a trajectory. (shrink)

David Gauthier develops morality in the social contract tradition as an emergent property rationally necessitated by the presence of inefficiency. To demarcate situations in which morality arises from those in which it does not, two principles, Strategic Emergence and Market Emergence, are motivated and assumed by Gauthier to be equivalent. Following the work of Bob Bright, this paper formalizes and expands upon a demonstration of the inconsistency of the two principles. Eliminating each of the emergence conditions is considered to resolve (...) the inconsistency. Additionally, the Kantian equilibrium is examined in place of the Nash equilibrium; however, Gauthier’s approach resists such amendments. (shrink)

Contractarianism initially made its mark, in the seventeenth century, as a sort of theory of everything in ethics. But gradually philosophers became convinced that there were resources available outside contractarianism for settling important moral questions—for instance, ideas of human rights and the moral equality of persons. Then Rawls revived contractarianism with a more modest aim—namely, as a theory of justice. But even this agenda for contractarianism has been called into question, most notably by G.A. Cohen, who contends that we have (...) other tools at our disposal for identifying the true conception of justice. So the question remains: how should contractarianism be construed if it is to provide answers to questions that cannot be answered in some other way? In my essay I offer a very simple answer: contractarianism should be construed as a political morality. I arrive at this answer by starting with contractarianism as a theory of everything and paring away the unappealing layers of contractarianism so understood. I begin by describing what contractarianism is. Then I dispense with contractarianism as a theory of state legitimacy, as a theory of interpersonal morality, and as a theory of justice. Finally, I distinguish political morality from the other already-mentioned areas of morality, and argue that contractarianism is a sensible theory of its grounds. (shrink)

In the contemporary philosophical debate, there are two opposing contractualist views. On the one side, Hobbesian contractualisms take moral principles as side-constraints to redress the failures of the interaction among self-interested individuals. On the other, Kantian versions of the social contract ground morality on an impartial and moralized viewpoint. In his recent Contractualism and the Foundations of Morality, Nicholas Southwood proposes a third and novel form of contractualism, with the aim to overcome the “implausibly personal and partial characterization of the (...) moral point of view” of Hobbesian positions, as well as the “excessively substantive conception of practical reason” of Kantian theories .On Southwood’s view, perfectly rational individuals—who see themselves as “simultaneously co-legislator and co-subject among individuals with whom one shares an authority as a fellow deliberative agent” —agree upon a “common code” to live by, which is “a relatively compreh ..

Philosophers and social scientists have recently turned to game theory and agent-based models to better understand social contract formation. The stag hunt game is an idealization of social contract formation. Using the stag hunt game, we attempt to determine what, if any, barrier diversity is to the formation of an efficient social contract. We uncover a deep connection between tolerance, diversity, and the social contract. We investigate a simple model in which individuals possess salient traits and behave cooperatively when the (...) difference between their trait and the trait of their counterpart is less than their ‘tolerance level’. If traits are fixed and correspond to permanent or semipermanent features of the individual, such as religion or race, social contract formation is a remote possibility. If traits are malleable, social contract formation is possible but comes at the steep cost of diversity and tolerance, that is, individuals are unwilling to cooperate with those much different from themselves. Yet homogeneity and intolerance are not a long-term feature of the population. Over time mutations allow for increasingly tolerant agents to prosper, thereby ushering in trait diversity. In the end, all reap the benefits of cooperation. (shrink)

This book questions the often implicit assumption of many contemporary political philosophers that a society needs its citizens to adopt some shared basic qualities, views, or capabilities. Christoph Luetge provides an alternative view, which relies on mutual advantages as the fundamental basis of society.

In a recent article, McClennen (2012) defends an alternative bargaining theory in response to his criticisms of the standard Nash bargaining solution as a principle of distributive justice in the context of the social contract. McClennen rejects the orthodox concept of expected individual utility maximizing behavior that underlies the Nash bargaining model in favor of what he calls full rationality, and McClennen’s full cooperation bargaining theory demands that agents select the most egalitarian strictly Pareto-optimal distributional outcome that is strictly Pareto-superior (...) to the state of nature. I argue that McClennen’s full cooperators are best described as reasonable agents whose rationality is constrained by moral considerations and that McClennen’s bargaining theory is moralized in this regard. If, by contrast, the orthodox concept of rationality is assumed and plausible assumptions are made about human nature and social cooperation, then a modified version of the standard Nash bargaining solution, which I call the stabilized Nash bargaining solution (Moehler 2010), is justified. From the perspective of rational agents, the stabilized Nash bargaining solution can accommodate McClennen’s criticisms of the standard Nash bargaining solution in the context of the social contract and, for such agents, it can serve as a principle of distributive justice in deeply morally pluralistic societies.

The question of what a group of rational agents would agree on were they to deliberate on how to organise society is central to all hypothetical social contract theories. If morality is to be based on a social contract, we need to know the terms of this contract. One type of social contract theory, contractarianism, aims to derive morality from rationality alone. Contractarians need to show, amongst other things, that rational and self-interested individuals would agree on an impartial division of (...) a cooperative surplus. But it is often claimed that contractarians cannot show this without introducing moral assumptions. This paper argues that on the right understanding of the question contractarians are asking, these worries can be answered. Without relying on moral assumptions, the paper offers a novel derivation of symmetry, which is the axiom responsible for the impartiality of the most famous economic bargaining solutions appealed to by contractarians. (shrink)

For contractarians, justice is the result of a rational bargain. The goal is to show that the rules of justice are consistent with rationality. The two most important bargaining theories of justice are David Gauthier’s and those that use the Nash’s bargaining solution. I argue that both of these approaches are fatally undermined by their reliance on a symmetry condition. Symmetry is a substantive constraint, not an implication of rationality. I argue that using symmetry to generate uniqueness undermines the goal (...) of bargaining theories of justice. (shrink)

Ordered social life requires rules of conduct that help generate and preserve peaceful and cooperative interactions among individuals. The problem is that these social rules impose costs. They prohibit us from doing some things we might see as important and they require us to do other things that we might otherwise not do. The question for the contractarian is whether the costs of these social rules can be rationally justified. I argue that traditional contract theories have tended to underestimate the (...) importance of evaluating the cost of enforcement and compliance in the contract procedure. In addition, the social contract has been understood narrowly as a method of justifying specifically moral or political rules. I defend a broader version of contractarianism as a justificatory model that can be used to evaluate any set of social rules or institutions that impose costson agents. In so doing, I argue that contractarianism is a general method of evaluating and justifying the rules that order the structure of social life. (shrink)

Bargaining and distribution of benefits accruing from social cooperation are central topics in contractarian accounts of morality or distributive justice in general and David Gauthier’s Morals by Agreement in particular. In this paper, I raise some problems for MbA both with regards to bargaining over the benefits of social cooperation and the distribution of such benefits. The worries I raise piggyback on a couple of Jan Narveson’s earlier queries of some of the topics in MbA: those of ‘questionable foundation’ and (...) redundancy. However, I go beyond the substance of these queries by arguing that they raise fundamental worries about the correctness of the description of the elements of the bargaining situation, and the role and significance of agreement in MbA.

I argue that social-contract theory cannot succeed because reasonable people may always disagree, and that social-contract theory is irrelevant to the problem of the legitimacy of a form of government or of a system of moral rules. I note the weakness of the appeal to implicit agreement, the conflation of legitimacy with stability, the undesirability of “public justification” and the apparent blindness to the evolutionary critical-rationalist approach of Hayek and Popper. I employ that approach to sketch answers to the theoretical, (...) historical and practical questions about the legitimacy of government or of systems of moral rules. (shrink)

Rawls developed a contractualist theory of social justice and Scanlon attempted to extend the Rawlsian framework to develop a theory of rightness, or morality more generally. I argue that there are some good reasons to adopt a contractualist theory of social justice, but that it is a mistake to adopt a contractualist theory of rightness. I begin by illustrating the major shared features of Scanlon and Rawls’ theories. I then show that the justification for these features in Rawls’ theory, the (...) centrality of cooperative fairness to social justice, cannot be used to defend their use in Scanlon’s. Finally, I argue that Scanlon has not provided an adequate alternative defense of these features, and show that they create problems when contractualists try to explain major features of our common-sense morality.

At the basis of modern natural law theories, the concept of the suum, or what belongs to the person (in Latin, his, her, its, their own), has received little scholarly attention despite its importance both in explaining and justifying not only the genealogy of property, but also that of morality and war.1 In this paper I examine Hugo Grotius's what it is, what things it includes, what rights it gives rise to and how it is extended in the transition from (...) the state of nature to civil society. I then briefly point out how bringing this concept back to the fore could help to illuminate the current discussion on the foundations of basic human rights, and to evaluate cases where these seem to clash with property rights.

Harsanyi defends utilitarianism by means of an axiomatic proof and by what he calls the 'equiprobability model'. Both justifications of utilitarianism aim to show that utilitarian ethics can be derived from Bayesian rationality and some weak moral constraints on the reasoning of rational agents. I argue that, from the perspective of Bayesian agents, one of these constraints, the impersonality constraint, is not weak at all if its meaning is made precise, and that generally, it even contradicts individual rational agency. Without (...) the impersonality constraint, Harsanyi's two justifications of utilitarianism on the grounds of Bayesian rationality fail. As an alternative, I develop a contractarian framework that is compatible with individual rational agency and Harsanyi's central assumptions, and that allows the derivation of moral conclusions on the grounds of Bayesian rationality. The developed framework offers a novel justification of contractarian ethics and may best be described as a combined version of Harsanyi's equiprobability model and Rawls's original position.

It is commonly thought that neo-Hobbesian contractarianism cannot yield direct moral standing for marginal humans and animals. However, it has been argued that marginal humans and animals can have a form of direct moral standing under neo-Hobbesian contractarianism: secondary moral standing. I will argue that, even if such standing is direct, this account is unsatisfactory because it is counterintuitive and fragile.

Epicurean contractarianism is an attempt to reconcile individualistic hedonism with a robust account of justice. The pursuit of pleasure and the requirements of justice, however, have seemed to be incompatible to many commentators, both ancient and modern. It is not clear how it is possible to reconcile hedonism with the demands of justice. Furthermore, it is not clear why, even if Epicurean contractarianism is possible, it would be necessary for Epicureans to endorse a social contract. I argue here that Epicurean (...) contractarianism is both possible and necessary once we understand Epicurean practical rationality in a new way. We are left with an appealing version of teleological, individualistic contractarianism that is significantly different from Hobbesian contractarianism. (shrink)

The twin ideas at the heart of the social contract tradition are that persons are naturally free and equal, and that genuine political obligations must in some way be based on the consent of those obligated. The Lockean tradition has held that consent must be in the form of explicit choice; Kantian contractualism has insisted on consent as rational endorsement. In this paper I seek to bring the Kantian and Lockean contract traditions together. Kantian rational justification and actual choice are (...) complementary devices through which our freedom and equality can be reconciled with moral and political authority. We should not think that there is simply one way by which relations of moral and political authority can be reconciled with our status as free and equal. I defend three distinct devices through which freedom and authority may be reconciled: justification to others, social choice and promise. All three are aspects of the ?consent tradition? broadly construed. (shrink)

In this article, I derive a weak version of Kant's categorical imperative within an informal game-theoretic framework. More specifically, I argue that Hobbesian agents would choose what I call the weak principle of universalization, if they had to decide on a rule of conflict resolution in an idealized but empirically defensible hypothetical decision situation. The discussion clarifies (i) the rationality requirements imposed on agents, (ii) the empirical conditions assumed to warrant the conclusion, and (iii) the political institutions that are necessary (...) to implement the derived principle. The analysis demonstrates the moral significance of the weak principle of universalization and its epistemic advantage over the categorical imperative. (shrink)

Some contractualist egalitarians try to accommodate a concern for numbers by embracing a pluralist strategy. They incorporate the belief that the number of people affected matters for what distribution one ought to bring about by arguing that their primary contractualist concern for justifiability to each may be outweighed by aggregative considerations. The present contribution offers two arguments against such a pluralist strategy. First, I argue that advo- cates of the pluralist strategy are forced to abandon the rationale behind the criterion (...) of universal acceptability. Second, I show that pluralist contractualists will be unable to avoid the dreaded conclusion that originally motivated their contractualism. Ultimately, these arguments matter for the nature of egalitarian- ism. They should give those in search of sound distributive principles a reason to make sense of their egalitarian commitment in a non-contractualist way. If a sound set of distributive principles includes comparative and relational princi- ples, while contractualist egalitarianism does not lend itself to being pluralistically combined with non-individualist principles, telic egalitarianism may after all be part of the truth in distributive ethics.

Imagine living in the future in a world already damaged by humankind, a world where resources are insufficient to meet everyone's basic needs and where a chaotic climate makes life precarious. Then imagine looking back into the past, back to our own time and assessing the ethics of the early twenty-first century. "Ethics for a Broken World" imagines how the future might judge us and how living in a time of global environmental degradation might utterly reshape the politics and ethics (...) of the future. This book is presented as a series of history of philosophy lectures given in the future, studying the classic texts from a past age of affluence, our own time. The central ethical questions of our time are shown to look very different from the perspective of a ruined world. The aim of "Ethics for a Broken" World is to look at our present with the benefit of hindsight - to reimagine contemporary philosophy in an historical context - and to highlight the contingency of our own moral and political ideals.

Mark Rowlands argues that, contrary to the dominant view, a Rawlsian theory of justice can legitimately be applied to animals. One of the implications of doing so, Rowlands argues, is an end to animal experimentation. I will argue, contrary to Rowlands, that under a Rawlsian theory there may be some circumstances where it is justifiable to use animals as experimental test subjects (where the individual animals are benefited by the experiments).

Does rational bargaining yield a social contract that is efficient and so inclusive? A core allocation, that is, an allocation that gives each coalition at least as much as it can get on its own, is efficient. However, some coalitional games lack a core allocation, so rationality does not require one in those games. Does rationality therefore permit exclusion from the social contract? I replace realization of a core allocation with another type of equilibrium achievable in every coalitional game. Fully (...) rational agents coordinate the pursuit of incentives so that equilibria of this type are efficient. They adopt a social contract that is efficient and inclusive. (shrink)

This paper offers a critique of David Gauthier’s contractarian moral theory. I point out morally counter-intuitive implications of Gauthier’s theory – for example, with respect to societies with slavery or concerning the protection of animals – as well as theoretically unattractive features, such as the overly optimistic assumption of translucent agents. However, contractarian moral theories can be improved by correcting the theoretically unattractive features. Moreover, though some morally counter-intuitive implications cannot be avoided, whether we should accept these implications ultimately depends (...) on whether an instrumentalist account of practical reason is defensible and how morality relates to practical reason. Thus, contractarian moral theories cannot be refuted as easily as one might think at first. (shrink)

Norbert Hoerster has tried to show on the basis of what I call special and general interests that it is rational to endorse moral judgements. I argue that Hoerster’s attempt to vindicate the rationality of moral judgements fails. By appealing to special interests Hoerster can only establish the rationality of endorsing judgements that – by Hoerster’s own standards – are not moral judgements because they do not pass the test of generalization. While the appeal to general interests, on the other (...) hand, indeed establishes the rationality of endorsing judgements that pass the test of generalization, it does so only for some but not all people; for this reason, the vindicated judgements do not qualify as moral judgements either.
