Preventive use of force may be defined as the initiation of military action in anticipation of harmful actions that are neither presently occurring nor imminent. This essay explores the permissibility of preventive war from a cosmopolitan normative perspective, one that recognizes the basic human rights of all persons, not just citizens of a particular country or countries. It argues that preventive war can only be justified if it is undertaken within an appropriate rule-governed, institutional framework that is designed to help (...) protect vulnerable countries against unjustified interventions while also avoiding unacceptable risks of the costs of inaction. The key to ensuring the fairness of rules governing the preventive use of force is accountability.This essay proposes a scheme that would make those promoting and those rejecting the preventive use of force more accountable. The proposal contains the following crucial features:States proposing preventive war are required to enter into a contract with a diverse body of states as a condition for authorization of their actions;Prior to taking preventive action, states must make an evidence-based case to the UN Security Council, and agree in advance to submit themselves to an evaluation by an impartial body after the preventive action occurred;Both proponents of action and those opposing it will be held accountable ex post for the accuracy of their prior statements and the proportionality of their actions;Sanctions will be imposed against intervening states or states that opposed preventive action, respectively, depending on the findings of the ex post evaluation.If preventive action were blocked in the Security Council, states seeking to engage in preventive action could then present their case in a different body–a coalition of democratic states–with its own ex post and ex ante accountability procedures.

Communication by scientists with policy makers and attentive publics raises ethical issues. Scientists need to decide how to communicate knowledge effectively in a way that nonscientists can understand and use, while remaining honest scientists and presenting estimates of the uncertainty of their inferences. They need to understand their own ethical choices in using scientific information to communicate to audiences. These issues were salient in the Fourth Assessment of the Intergovernmental Panel on Climate Change with respect to possible sea level rise (...) from disintegration of the Greenland and West Antarctic ice sheets. Due to uncertainty, the reported values of projected sea level rise were incomplete, potentially leading some relevant audiences to underestimate future risk. Such judgments should be made in a principled rather than an ad hoc manner. Five principles for scientific communication under such conditions are important: honesty, precision, audience relevance, process transparency, and specification of uncertainty about conclusions. Some of these principles are of intrinsic importance while others are merely instrumental and subject to trade-offs among them. Scientists engaged in assessments under uncertainty should understand these principles and which trade-offs are acceptable. (shrink)

The authors articulate a global public standard for the normative legitimacy of global governance institutions. This standard can provide the basis for principled criticism of global governance institutions and guide reform efforts in circumstances in which people disagree deeply about the demands of global justice and the role that global governance institutions should play in meeting them.

'The genocide in Rwanda showed us how terrible the consequences of inaction can be in the face of mass murder. But the conflict in Kosovo raised equally important questions about the consequences of action without international consensus and clear legal authority. On the one hand, is it legitimate for a regional organization to use force without a UN mandate? On the other, is it permissible to let gross and systematic violations of human rights, with grave humanitarian consequences, continue unchecked?'. This (...) book is a comprehensive, integrated discussion of 'the dilemma' of humanitarian intervention. Written by leading analysts of international politics, ethics, and law, it seeks, among other things, to identify strategies that may, if not resolve, at least reduce the current tension between human rights and state sovereignty. This volume is an invaluable contribution to the debate on all aspects of this vital global issue. (shrink)

The author argues that all governments are morally obliged to support international institutions that advocate crosscultural and global public goods to advance the fairness principle.

The central institutions of the United Nations have substantially lost moral authority since the Millennium Summit of 2000.

In their article “Just War and Unjust Soldiers: American Public Opinion on the Moral Equality of Combatants,” Scott Sagan and Benjamin Valentino argue that the American public evaluates soldiers’ wartime actions more according to whether the war they are fighting was initiated justly, than on their actions during warfare. In this respect, their views are more similar to those of revisionist philosophers than to those of traditional just war theorists. Before leaping to broad conclusions from their survey, it should be (...) replicated. If the findings hold in the replication, intriguing questions could be asked about comparative cross-national attitudes and about the relationship between democracy and war. (shrink)

As global governance institutions proliferate and become more powerful, their legitimacy is subject to ever sharper scrutiny. Yet what legitimacy means in this context and how it is to be ascertained are often unclear. In a previous paper in this journal, we offered a general account of the legitimacy of such institutions and a set of standards for determining when they are legitimate. In this paper we focus on the legitimacy of the UN Security Council as an institution for making (...) decisions concerning the use of military force across state borders. The context for this topic has changed over the last decade as a result of the ongoing development of the responsibility to protect (RtoP) doctrine and extensive discussions about it in the United Nations. Yet the mostly widely accepted proposals for RtoP still require Security Council authorization for forceful intervention, and strictly limit the conditions under which such intervention may take place.

Allen Buchanan and Robert O. Keohane reply to Steven Lee's critique of their previous essay on the preventive use of military force.

International Rules brings together exemplary works from the most prominent approaches to international rules of International Law and International Relations disciplines. Included are chapters on Natural Law, Legal Positivism, Classical Realism, the New Haven School, Institutionalism, Structural Realism, the New Stream, and Feminist Voices. Each of the eight chapters begins with a brief overview, offers a representative work or works, and concludes with a selected bibliography. From Hugo Grotius to David Kennedy, from George Kennan to Robert Keohane, the (...) featured authors provide valuable insights into their common subject: international rules. Despite divergent methods and objectives, they address fundamentally the same questions: What is the nature of such rules? What is their purpose? How do they originate? What role, if any, do they play in politics? Framing the selections assembled are two original chapter-length essays. The first chapter of this volume assesses the prospects for interdisciplinary collaboration; the final one suggests a direction for future research. (shrink)

Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.

In their contributions to the symposium “Just War and Unjust Soldiers,” Michael Walzer, Jeff McMahan, and Robert O. Keohane add greatly to our understanding of how best to study and apply just war doctrine to real-world conflicts. We argue, however, that they underestimate both the degree to which the American public seeks revenge, rather than just reciprocity, and the extent of popular acceptance of violations of noncombatant immunity by soldiers perceived to be fighting for a just cause. We (...) call on empirical political scientists, lawyers, psychologists, and historians to engage with moral philosophers and political theorists in debates about the influence of just war theory and the laws of armed conflict.

In a recent article Allan Buchanan and Robert Keohane defend the view that one of the necessary conditions for the legitimacy of global governance institutions such as the WTO and the IMF is that they respect basic human rights. I certainly agree that setting the minimal threshold of moral acceptability any lower would be entirely unreasonable. But, unfortunately, the view that global governance institutions have human rights obligations is far from uncontroversial. These institutions themselves go to great lengths (...) to deny such a claim. Their official stance finds strong normative support in the state-centric conception of human rights that dominates both normative debates about human rights and current human rights practice. In this article I challenge some of the normative assumptions behind the state-centric conception in order to defend a pluralist conception that ascribes human rights obligations not only to states but also to non-state actors such as global governance institutions. After briefly analyzing some of the proposals currently under discussion about how to legally entrench the obligation to respect human rights in those institutions, I will defend the feasibility of those proposals against the objection that their implementation is incompatible with the current state-system and thus it would require the creation of a world state.

Steven Lee critiques an essay by Allen Buchanan and Robert Keohane on the preventive use of military force.

In its most recent form, the debate about the relationship between quantitative and qualitative methodology in political science has been shaped by the publication of Designing Social Inquiry: Scientific Inference in Qualitative Research by Gary King, Robert O. Keohane, and Sidney Verba in 1994 (hereafter DSI). The focus of this debate has been case study research. DSI advocates that qualitative research, particularly case study research, be modeled on the template of quantitative research. The authors claim that all research (...) has the same logic of inquiry and that this is most clearly exemplified in quantitative work. I argue that the underlying philosophy of science of DSI is monistic and positivistic in ways not productive for understanding various different purposes that political science knowledge may have. Different methodologies have different strengths and so are suited to different ends. I examine this in relation to Julian Reiss’s discussion of different concepts of causality and argue that case study research is suited to understanding causal mechanisms in ways that make such research better suited to inform policy decisions. I finish with an example using David Fearon’s 2006 Congressional Testimony on Iraq. (shrink)

Robert Alexy develops his influential theory of legal reasoning exploring the nature of legal argumentation and its relation to practical reasoning. In doing so he sheds light on fundamental questions of law and rationality, which are as crucial to practising lawyers and law students as they are to scholars of legal theory.

An increasingly prevalent practice in defending current concepts of democracy is to make it synonymous with Americanization. Creating a world order permeated by the economic and cultural values of contemporary Western elites is taken to be equivalent to promoting a democratic future for everyone in The Real World Order — a work by two futurologists, Max Singer and Aaron Wildavsky, praised by such global democratic advocates as Robert O. Keohane, Francis Fukuyama, Bruce Bueno de Mesquita, and by the (...) Times Literary Supplement for its “injection of sensible balance into discussions of international relations.” Singer and Wildavsky explain that although “democracy and modern wealth are new in the world,” they have now come to define the major economic and political powers.

At the heart of this book is the age-old question of how law and morality are related. The legal positivist, insisting on the separation of the two, explicates the concept of law independently of morality. The author challenges this view, arguing that there are, first, conceptually necessary connections between law and morality and, second, normative reasons for including moral elements in the concept of law. While the conceptual argument alone is too limited to establish a sufficiently strong connection between law (...) and morality, and the normative argument alone fails to address the nature of law, the two arguments together support a nonpositivistic concept of law, toppling legal positivism qua comprehensive theory of law.

This book analyses the general structure of constitutional rights reasoning under the German Basic Law. It deals with a wide range of problems common to all systems of constitutional rights review. In an extended introduction the translator argues for its applicability to the British Constitution, with particular reference to the Human Rights Act 1998.

Robert Batterman examines a form of scientific reasoning called asymptotic reasoning, arguing that it has important consequences for our understanding of the scientific process as a whole. He maintains that asymptotic reasoning is essential for explaining what physicists call universal behavior. With clarity and rigor, he simplifies complex questions about universal behavior, demonstrating a profound understanding of the underlying structures that ground them. This book introduces a valuable new method that is certain to fill explanatory gaps across disciplines.

Robert Stalnaker opposes the traditional view that knowledge of one's own current thoughts and feelings is the unproblematic foundation for all knowledge. He argues that we can understand our knowledge of our thoughts and feelings only by viewing ourselves from the outside, by seeing our inner lives as features of the world as it is in itself.

Where does the mind begin and end? Most philosophers and cognitive scientists take the view that the mind is bounded by the skull or skin of the individual. Robert Wilson, in this provocative and challenging 2004 book, provides the foundations for the view that the mind extends beyond the boundary of the individual. The approach adopted offers a unique blend of traditional philosophical analysis, cognitive science, and the history of psychology and the human sciences. The companion volume, Genes and (...) the Agents of Life, explores the theme in the biological sciences. Written with verve and clarity, this ambitious book will appeal to a broad swathe of professionals and students in philosophy, psychology, cognitive science, and the history of the behavioural and human sciences.

In Overdoing Democracy, Robert B. Talisse turns the popular adage "the cure for democracy's ills is more democracy" on its head. Indeed, he argues, the widely recognized, crisis-level polarization within contemporary democracy stems from the tendency among citizens to overdo democracy. When we make everything--even where we shop, the teams we cheer for, and the coffee we drink--about our politics, we weaken our bonds to one another, and work against the fundamental goals of democracy. Talisse advocates civic friendship built (...) around shared endeavors that we must undertake with fellow citizens who do not necessarily share our political affinities as the best way we can obtain a healthier, more sustainable democracy.

This volume collects thirty years worth of articles on the emotions written by the distinguished philosopher Robert Solomon. Solomon's thesis is that we are significantly responsible for our emotions, which are evaluative judgments that in effect we choose. This is the first of several volumes that document work in the emotions.

There are two basic views concerning the relationship between constitutional rights and proportionality analysis. The first maintains that there exists a necessary connection between constitutional rights and proportionality, the second argues that the question of whether constitutional rights and proportionality are connected depends on what the framers of the constitution have actually decided, that is, on positive law. The first thesis may be termed ‘necessity thesis’, the second ‘contingency thesis’. According to the necessity thesis, the legitimacy of proportionality analysis is (...) a question of the nature of constitutional rights, according to the contingency thesis, it is a question of interpretation. The article defends the necessity thesis. | A previous version of this article was published in Chinese Yearbook of Constitutional Law, Vol. 2010, 221–235. (shrink)

The author's thesis is that there is a conceptually necessary connection between law and morality which means legal positivism must fail as a comprehensive theory. The substantiation of this thesis takes place within a conceptual framework which shows that there are at least 64 theses to be distinguished, concerning the relationship of law and morality. The basis for the author's argument in favour of a necessary connection, is formed by the thesis that individual legal norms and decisions as well as (...) whole legal systems necessarily make a claim to correctness. The explication of this claim within the frame of discourse theory shows that the law has a conceptually necessary, ideal dimension, which connects law with a procedural, universalistic morality.

This book articulates and defends Fregean realism, a theory of properties based on Frege's insight that properties are not objects, but rather the satisfaction conditions of predicates. Robert Trueman argues that this approach is the key not only to dissolving a host of longstanding metaphysical puzzles, such as Bradley's Regress and the Problem of Universals, but also to understanding the relationship between states of affairs, propositions, and the truth conditions of sentences. Fregean realism, Trueman suggests, ultimately leads to a (...) version of the identity theory of truth, the theory that true propositions are identical to obtaining states of affairs. In other words, the identity theory collapses the gap between mind and world. This book will be of interest to anyone working in logic, metaphysics, the philosophy of language or the philosophy of mind. (shrink)

Philosophy is general and systematic reflection about what there is, what ought to be done or is good, and how knowledge about both is possible. Legal philosophy raises these questions with respect to the law. In so doing, legal philosophy is engaged in reasoning about the nature of law. The arguments addressed to the question of the nature of law revolve around three problems. The first problem addresses the question: In what kinds of entities does the law consist, and how (...) are these entities connected such that they form the overarching entity we call “law”? The answer is that law consists of norms as meaning contents which form a normative system. The second problem addresses the question of how norms as meaning contents are connected with the real world. This connection can be grasped by means of the concepts of authoritative issuance and social efficacy. The latter includes the concept of coercion or force. The third problem addresses the correctness or legitimacy of law, and, by this, the relationship between law and morality. To ask about the nature of law is to ask about necessary relations between the concepts of normative meaning, authoritative issuance as well as social efficacy, and correctness of content. (shrink)

We live our lives through our emotions, writes Robert Solomon, and it is our emotions that give our lives meaning. What interests or fascinates us, who we love, what angers us, what moves us, what bores us--all of this defines us, gives us character, constitutes who we are. In True to Our Feelings, Solomon illuminates the rich life of the emotions--why we don't really understand them, what they really are, and how they make us human and give meaning to (...) life. Emotions have recently become a highly fashionable area of research in the sciences, with brain imaging uncovering valuable clues as to how we experience our feelings. But while Solomon provides a guide to this cutting-edge research, as well as to what others--philosophers and psychologists--have said on the subject, he also emphasizes the personal and ethical character of our emotions. He shows that emotions are not something that happen to us, nor are they irrational in the literal sense--rather, they are judgements we make about the world, and they are strategies for living in it. Fear, anger, love, guilt, jealousy, compassion--they are all essential to our values, to living happily, healthily, and well. Solomon highlights some of the dramatic ways that emotions fit into our ethics and our sense of the good life, how we can make our emotional lives more coherent with our values and be more "true to our feelings" and cultivate emotional integrity. The story of our lives is the story of our passions. We fall in love, we are gripped by scientific curiosity and religious fervor, we fear death and grieve for others, we humble ourselves in envy, jealousy, and resentment. In this remarkable book, Robert Solomon shares his fascination with the emotions and illuminates our passions in an exciting new way. (shrink)

Presenting the history of space-time physics, from Newton to Einstein, as a philosophical development DiSalle reflects our increasing understanding of the connections between ideas of space and time and our physical knowledge. He suggests that philosophy's greatest impact on physics has come about, less by the influence of philosophical hypotheses, than by the philosophical analysis of concepts of space, time and motion, and the roles they play in our assumptions about physical objects and physical measurements. This way of thinking leads (...) to interpretations of the work of Newton and Einstein and the connections between them. It also offers ways of looking at old questions about a priori knowledge, the physical interpretation of mathematics, and the nature of conceptual change. Understanding Space-Time will interest readers in philosophy, history and philosophy of science, and physics, as well as readers interested in the relations between physics and philosophy. (shrink)

Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn't have been instantiated. These views motivate Stalnaker's "two dimensional" account of the necessary a posteriori on which there is no single proposition that is both necessary and a posteriori. For a (metaphysically) necessary proposition is true in all (metaphysically) possible worlds. If there were necessary a posteriori (...) propositions, that would mean that there were propositions true in all possible worlds but which could only be known to be true by acquiring empirical evidence. Consider such a purported proposition P. The role of empirical evidence for establishing P's truth would have to be to rule out worlds in which P is false. If there were no such worlds to be ruled out, we would not require evidence for P. But by hypothesis, P is necessary and so true in all metaphysically possible worlds. And on Stalnaker's view, the metaphysically possible worlds are all the worlds there are. So there can be no proposition that is true in all possible worlds, but that we require evidence to know. In this way, the motivation for Stalnaker's two dimensional account of the necessary a posteriori rests on his denying that there are metaphysically impossible Worlds. I argue that given his view of what possible worlds are, Stalnaker has no principled reason for denying that there are metaphysically impossible worlds. If I am right, this undercuts Stalnaker's motivation for his two dimensional account of the necessary a posteriori. (shrink)

Contemporary discussions about practical reason or practical rationality invoke four competing views which can be named as follows by reference to their historical models: Aristotelian, Hobbesian, Kantian and Nietzschean. The subject-matter of this article is a defence of the Kantian conception of practical rationality in the interpretation of discourse theory. At the heart, lies the justification and the application of the rules of discourse. An argument consisting of three parts is pre sented to justify the rules of discourse. The three (...) parts are as follows: a transcen dental-pragmatic argument; an argument which takes account of the maximisation of individual utility and an empirical premise about an interest in correctness. Within the framework of the problem of application, the article outlines a justification of human rights and of the basic institutions of the democratic constitutional state on the basis of discourse theory.

In this significant contribution to Hegel scholarship, Robert Williams develops the most comprehensive account to date of Hegel's concept of recognition. Fichte introduced the concept of recognition as a presupposition of both Rousseau's social contract and Kant's ethics. Williams shows that Hegel appropriated the concept of recognition as the general pattern of his concept of ethical life, breaking with natural law theory yet incorporating the Aristotelian view that rights and virtues are possible only within a certain kind of community. (...) He explores Hegel's intersubjective concept of spirit as the product of affirmative mutual recognition and his conception of recognition as the right to have rights. Examining Hegel's Jena manuscripts, his _Philosophy of Right_, the _Phenomenology of Spirit_, and other works, Williams shows how the concept of recognition shapes and illumines Hegel's understandings of crime and punishment, morality, the family, the state, sovereignty, international relations, and war. A concluding chapter on the reception and reworking of the concept of recognition by contemporary thinkers including Derrida, Levinas, and Deleuze demonstrates Hegel's continuing centrality to the philosophical concerns of our age.

[Robert Stalnaker] Saul Kripke made a convincing case that there are necessary truths that are knowable only a posteriori as well as contingent truths that are knowable a priori. A number of philosophers have used a two-dimensional model semantic apparatus to represent and clarify the phenomena that Kripke pointed to. According to this analysis, statements have truth-conditions in two different ways depending on whether one considers a possible world 'as actual' or 'as counterfactual' in determining the truth-value of the (...) statement relative to that possible world. There are no necessary a posteriori or contingent a priori propositions: rather, contingent a priori and necessary a posteriori statements are statements that are necessary when evaluated one way, and contingent when evaluated the other way. This paper distinguishes two ways that the two-dimensional framework can be interpreted, and argues that one of them gives the better account of what it means to 'consider a world as actual', but that it provides no support for any notion of purely conceptual a priori truth. /// [Thomas Baldwin] Two-dimensional possible world semantic theory suggests that Kripke's examples of the necessary a posteriori and contingent a priori should be handled by interpreting names as implicitly indexical. Like Stalnaker, I reject this account of names and accept that Kripke's examples have to be accommodated within a metasemantic theory. But whereas Stalnaker maintains that a metasemantic approach undermines the conception of a priori truth, I argue that it offers the opportunity to develop a conception of the a priori aspect of stipulations, conceived as linguistic performances. The resulting position accommodates Kripke's examples in a way which is both intrinsically plausible and fits with Kripke's actual discussion of them. (shrink)

Human beings, like other organisms, are the products of evolution. Like other organisms, we exhibit traits that are the product of natural selection. Our psychological capacities are evolved traits as much as are our gait and posture. This much few would dispute. Evolutionary psychology goes further than this, claiming that our psychological traits -- including a wide variety of traits, from mate preference and jealousy to language and reason -- can be understood as specific adaptations to ancestral Pleistocene conditions. In (...) Evolutionary Psychology as Maladapted Psychology, Robert Richardson takes a critical look at evolutionary psychology by subjecting its ambitious and controversial claims to the same sorts of methodological and evidential constraints that are broadly accepted within evolutionary biology. The claims of evolutionary psychology may pass muster as psychology; but what are their evolutionary credentials? Richardson considers three ways adaptive hypotheses can be evaluated, using examples from the biological literature to illustrate what sorts of evidence and methodology would be necessary to establish specific evolutionary and adaptive explanations of human psychological traits. He shows that existing explanations within evolutionary psychology fall woefully short of accepted biological standards. The theories offered by evolutionary psychologists may identify traits that are, or were, beneficial to humans. But gauged by biological standards, there is inadequate evidence: evolutionary psychologists are largely silent on the evolutionary evidence relevant to assessing their claims, including such matters as variation in ancestral populations, heritability, and the advantage offered to our ancestors. As evolutionary claims they are unsubstantiated. Evolutionary psychology, Richardson concludes, may offer a program of research, but it lacks the kind of evidence that is generally expected within evolutionary biology. It is speculation rather than sound science -- and we should treat its claims with skepticism. (shrink)

Why democracy? Most often this question is met with an appeal to some decidedly moral value, such as equality, liberty, dignity or even peace. But in contemporary democratic societies, there is deep disagreement and conflict about the precise nature and relative worth of these values. And when democracy votes, some of those who lose will see the prevailing outcome as not merely disappointing, but morally intolerable. How should citizens react when confronted with a democratic result that they regard as intolerable? (...) Should they revolt, or instead pursue democratic means of social change? In this book, Robert Talisse argues that each of us has reasons to uphold democracy - even when it makes serious moral errors - and that these reasons are rooted in our most fundamental epistemic commitments. His original and compelling study will be of interest to a wide range of readers in political philosophy and political theory. (shrink)

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.
