Michael Otsuka sets out to vindicate left-libertarianism, a political philosophy which combines stringent rights of control over one's own mind, body, and life with egalitarian rights of ownership of the world. Otsuka reclaims the ideas of John Locke from the libertarian Right, and shows how his Second Treatise of Government provides the theoretical foundations for a left-libertarianism which is both more libertarian and more egalitarian than the Kantian liberal theories of John Rawls and Thomas Nagel. Otsuka's libertarianism is founded on (...) a right of self-ownership. Here he is at one with 'right-wing' libertarians, such as Robert Nozick, in endorsing the highly anti-paternalistic and anti-moralistic implications of this right. But he parts company with these libertarians in so far as he argues that such a right is compatible with a fully egalitarian principle of equal opportunity for welfare. In embracing this principle, his own version of left-libertarianism is more strongly egalitarian than others which are currently well known. Otsuka argues that an account of legitimate political authority based upon the free consent of each is strengthened by the adoption of such an egalitarian principle. He defends a pluralistic, decentralized ideal of political society as a confederation of voluntary associations. Part I of Libertarianism without Inequality concerns the natural rights of property in oneself and the world. Part II considers the natural rights of punishment and self-defence that form the basis for the government's authority to legislate and punish. Part III explores the nature and limits of the powers of governments which are created by the consensual transfer of the natural rights of the governed. Libertarianism without Inequality is a book which everyone interested in political theory should read. (shrink)

I defend an incompatibilist 'Principle of Avoidable Blame' according to which one is blameworthy for performing an act of a given type only if one could instead have behaved in a manner for which one would have been blameless. First, I demonstrate that this principle is resistant to Harry Frankfurt-type counterexample. Second, I present a positive argument for this principle that appeals to the relation of blame to the 'reactive attitude' of indignation. Finally, I argue against the possibility of blamelessly (...) stumbling into a 'moral blind alley' where one would be blameworthy for whatever one is capable of doing. (shrink)

We discuss two leading theories of distributive justice: egalitarianism and prioritarianism. We argue that while each has particular merits and shortcomings, egalitarian views more fully satisfy a key requirement of distributive justice: respect for both the unity of the individual and the separateness of persons.

We argue that there is a marked shift in the moral weight of an increment in a person's well-being when one moves from a case involving only intra-personal trade-offs to a case involving only inter-personal trads-offs. This shift, we propose, is required by the separateness of persons. We also argue that the Priority View put forward by Parfit cannot account for such a shift. We also outline two alternative views, an egalitarian view and a claims-based view, that can account for (...) this shift. (shrink)

I argue that prioritarianism cannot be assessed in abstraction from an account of the measure of utility. Rather, the soundness of this view crucially depends on what counts as a greater, lesser, or equal increase in a person’s utility. In particular, prioritarianism cannot accommodate a normatively compelling measure of utility that is captured by the axioms of John von Neumann and Oskar Morgenstern’s expected utility theory. Nor can it accommodate a plausible and elegant generalization of this theory that has been (...) offered in response to challenges to von Neumann and Morgenstern. This is, I think, a theoretically interesting and unexpected source of difficulty for prioritarianism, which I explore in this article. (shrink)

Mike Otsukaʼs book aspires to do more than its title discloses. Libertarianism without Inequality (Oxford University Press, 2003) does not merely aim to reconcile liberty and equality (that is handled without remainder in the first chapter) but to draw the outlines of a complete, and distinctly Lockean, political theory. Rather than starting from first principles, Otsuka explores several specific issues only loosely connected to each other, hoping that these might add up to a complete political vision. Though the discussion is (...) clearly tinted in Lockean colours, his conclusions are always provocative and difficult to swallow, even for modern disciples of Locke. Thus he argues for the following theses. (shrink)

For a prioritarian by contrast to a utilitarian, whether a certain quantity of utility falls within the boundary of one person's life or another's makes the following moral difference: the worse the life of a person who could receive a given benefit, the stronger moral reason we have to confer this benefit on this person. It would seem, therefore, that prioritarianism succeeds, where utilitarianism fails, to ‘take seriously the distinction between persons’. Yet I show that, contrary to these appearances, prioritarianism (...) fails, in ways strikingly parallel to those in which utilitarianism fails, to take this distinction seriously. In so doing, I draw on and develop an earlier critique of prioritarianism by disentangling and pressing two distinct separateness-of-persons objections offered there. One objection is that prioritarianism is insensitive to ‘prudential justifications’. The other is that it is insensitive to the competing claims of different individuals. (shrink)

In "What We Owe to Each Other", T. M. Scanlon argues that one should save the greater number when faced with the choice between saving one life and two or more different lives. It is, Scanlon claims, a virtue of this argument that it does not appeal to the claims of groups of individuals but only to the claims of individuals. I demonstrate that this argument for saving the greater number, indeed, depends, contrary to what Scanlon says, upon an appeal (...) to the claim of a group of individuals to be saved. (shrink)

This study investigates the influence of a robot's speech rate. In human communication, slow speech is considered boring, speech at normal speed is perceived as credible, and fast speech is perceived as competent. To seek the appropriate speech rate for robots, we test whether these tendencies are replicated in human-robot interaction by conducting an experiment with four rates of speech: fast, normal, moderately slow, and slow. Our experimental results reveal a rather surprising trend. Participants prefer normal and moderately slow speech (...) to fast speech. A robot that provides normal or moderately slow speech is perceived as competent. We further study how context affects this perception. In a situation where the robot and participants talk while walking, we found that slow speech was the most comprehensible. In addition, slow speech is subjectively perceived as good as moderately slow and normal speech. Keywords: Human-robot interaction; speech rate. (shrink)

English version of: "Il personale e politico? Il confine fra pubblico e privato nella sfera della giustizia distributiva." --- Italian text published in Carter, Ian, Otsuka, Michael and Trincia, Francesco Saverio Discussione su "If You're an Egalitarian, How Come You're So Rich?" di G.A. Cohen. Iride, XIV. pp. 609-634. ISSN 1122-7893.

This is the second of three volumes of posthumously collected writings of G. A. Cohen, who was one of the leading, and most progressive, figures in contemporary political philosophy. This volume brings together some of Cohen's most personal philosophical and nonphilosophical essays, many of them previously unpublished. Rich in first-person narration, insight, and humor, these pieces vividly demonstrate why Thomas Nagel described Cohen as a "wonderful raconteur." The nonphilosophical highlight of the book is Cohen's remarkable account of his first trip (...) to India, which includes unforgettable vignettes of encounters with strangers and reflections on poverty and begging. Other biographical pieces include his valedictory lecture at Oxford, in which he describes his philosophical development and offers his impressions of other philosophers, and "Isaiah's Marx, and Mine," a tribute to his mentor Isaiah Berlin. Other essays address such topics as the truth in "small-c conservatism," who can and can't condemn terrorists, and the essence of bullshit. A recurring theme is finding completion in relation to the world of other human beings. Engaging, perceptive, and empathetic, these writings reveal a more personal side of one of the most influential philosophers of our time. (shrink)

Over the past decade philosophers of biology have discussed whether evolutionary theory is a causal theory or a phenomenological study of evolution based solely on the statistical features of a population. This article reviews this controversy from three aspects, respectively concerning the assumptions, applications, and explanations of evolutionary theory, with a view to arriving at a definite conclusion in each contention. In so doing I also argue that an implicit methodological assumption shared by both sides of the debate, namely the (...) overconfidence in conceptual analysis as a tool to understand the scientific theory, is the real culprit that has both generated the problem and precluded its solution for such a long time.

The aim of this article is to refute Ronald Dworkin's claim that the provision of an equal opportunity to insure against risks is sufficient to render differences in people's circumstances that are the result of luck consistent with his theory of equality of resources. Section I addresses bad luck in the circumstances of individuals in the form of mental or physical incapacitation resulting from the vicissitudes of nature. Section II addresses bad luck which is the result of the choices of (...) other individuals to give or bequeath. (shrink)

The causal nature of evolution is one of the central topics in the philosophy of biology. The issue concerns whether equations used in evolutionary genetics point to some causal processes or purely phenomenological patterns. To address this question the present article builds well-defined causal models that underlie standard equations in evolutionary genetics. These models are based on minimal and biologically plausible hypotheses about selection and reproduction, and generate statistics to predict evolutionary changes. The causal reconstruction of the evolutionary principles shows (...) adaptive evolution as a genuine causal process, where fitness and selection are both causes of evolution. 1 Introduction2 The Philosophical Puzzle3 Causal Models4 Causal Foundations of Evolutionary Genetics4.1 Univariate quantitative genetics model4.1.1 The causal graph4.1.2 Structural equations4.1.3 Deriving evolutionary transition functions4.2 One-locus population genetics model5 Evolution as a Causal Process5.1 Selection as a causal process5.2 Causes of evolutionary change6 Conclusion.

Some are blameless for posing a threat to the live of another because they are not morally responsible for being a threat. Others are blameless in spite of their responsibility. On what has come to be known as the "moral responsibility account" of liability to defensive killing, it is such responsibility, rather than blameworthiness, for threatening another that renders one liable to defensive killing. Moreover, one's lack of responsibility for being a threat grounds one's nonliability to defensive killing. In "Killing (...) the Innocent in Self-Defense" (1994), I offered an early formulation and defense of such an account. In Section I of this chapter, I renew my defense of the claim that it is impermissible to kill a passive nonresponsible threat in self-defense. In Section II, I renew my defense of the claim that it is permissible to kill a blameless but morally responsible threat in self-defense. (shrink)

Rawlsian justice as fairness is neither fundamentally luck egalitarian nor relational egalitarian. Rather, the most fundamental idea is that of society as a fair system of cooperation. Collective pensions provide a case study which illustrates the fruitfulness of conceiving justice in these latter terms. Those who have recently reached the age of majority do not now know how long they will live in retirement or how well any investments they try to save up for their retirement would fare. From the (...) perspective of the beginning of their working lives, it is therefore rational for each to enter into an agreement with others, who also do not yet know their fates, that, if one turns out to be among the unfortunate whose private pension pots would not have yielded enough for one’s retirement, one will receive much more in retirement, whereas those whose pension pots would have overflowed their retirements will receive somewhat less. These terms are to each person’s expected advantage, which is made possible by a fair sharing of the fruits of social cooperation which arise through the efficiencies reaped by the pooling of the risk of outliving what one could save for one’s retirement on one’s own. It is rational for each to agree to share one another’s fates by pooling risks across both space and time, on fair terms of social cooperation for mutual advantage. Even when collective pensions arise from, and are proportional to, a baseline of unequal income, they can be defended on grounds of reciprocity involving regard for one another as equals. (shrink)

In this article, I argue that it makes a moral difference whether an individual is worse off than she could have been. Here, I part company with consequentialists such as Parfit and side with contractualists such as Scanlon. But, unlike some contractualists, I reject the view that all that matters is whether a principle can be justified to each particular individual, where such a justification is attentive to her interests, complaints and other claims. The anonymous goodness of a distribution also (...) matters. My attempt to reconcile contractualist and consequentialist approaches proceeds via a serious of reflections on cases. (shrink)

An argument against Parfit's view (in his chapter of Reasons and Persons on five mistakes in moral mathematics) that, rather than maximizing the difference one makes as an individual, one should join that group whose members together make the most positive difference in cases involving imperceptible benefits. It is shown how Parfit's defence of this view has the problematic implication either (1) that each outcome is less beneficial than itself or (2) that "less beneficial than" is not transitive.

Most deontologists find bedrock in the Pauline doctrine that it is morally objectionable to do evil in order that good will come of it. Uncontroversially, this doctrine condemns the killing of an innocent person simply in order to maximize the sum total of happiness. It rules out the conscription of a worker to his or her certain death in order to repair a fault that is interfering with the live broadcast of a World Cup match that a billion spectators have (...) been enjoying. It rules out such sacrifice even if it would maximize the sum total of everyone's happiness. An act utilitarian, by contrast, would require the sacrifice of the one whenever this latter condition obtains, since such a utilitarian is committed to the view that one ought always to act so as to bring about the greatest sum total of happiness. An act utilitarian might, however, consistently hold that a large number of rather insignificant pleasures, such as that which a spectator derives from witnessing men in shorts running around and kicking a ball, is never sufficient to justify the infliction of a great harm on a single individual. 4 He might take such a position without abandoning utilitarianism by denying that the sum total of such minor pleasures could ever be sufficiently great to outweigh the harm of death to the one. Under the inspiration of John Stuart Mill, a utilitarian might draw a more general distinction between serious and trivial harms and pleasures and maintain that no amount of a trivial pleasure could ever amount to a sum of happiness that is greater than the disutility of a serious harm.

Article (English translation of French article in Raisons Politiques).

All left-libertarians believe that natural resources should be governed by an egalitarian principle of distribution. In my own case, this belief gains its support from what I take to be the most defensible interpretation of the Lockean principle of justice in acquisition, according to which one may privatize land and other worldly resources in a state of nature so long as one leaves enough and as good for others. Axel Gosseries is right to press the question of the moral status (...) of worldly resources in a state of nature prior to private acquisition. For Locke, that status was one of common ownership, underwritten by God’s gift of the earth to humankind in common. For Léon Walras, to whom Vincent Bourdeau draws our attention, the earth both initially and inalienably belongs to humanity, and such collective ownership is grounded, not in theistic assumptions, but in the “scientific observation” that human beings are by nature social beings. By contrast, I regard the earth as initially unowned. This supposition should not, however, be understood, as it is by some, as the claim that each is equally free at the outset to privatize any bit of the world as he sees fit as a matter of right. Rather, it should be understood as an initial non-presumption of any rights with respect to the world. Rather than asserting the existence of rights that, as a moral default position, we have with respect to pristine wilderness, I am making a claim that is motivated by the methodological impropriety of presuming any rights with respect to the world at the outset.

Suppose that each of the following four conditions obtains: 1. You can save either a greater or a lesser number of innocent people from (equally) serious harm. 2. You can do so at trivial cost to yourself. 3. If you act to save, then the harm you prevent is harm that would not have been prevented if you had done nothing. 4. All other things are equal. A skeptic about saving the greater number rejects the common-sensical claim that you have (...) a duty to save the greater number in such circumstances. (shrink)

Cohen endorses the coercive taxation of the talented at a progressive rate for the sake of realizing equality. By contrast, he denies that it is legitimate for the state to engage in the 'Stalinist forcing' of people into one or another line of work in order to bring about a more egalitarian society. He rejects such occupational conscription on grounds of the invasiveness of the gathering and acting upon information regarding people's preferences for different types of work that would be (...) required to implement such a policy. More precisely, Cohen maintains that the presence versus the absence of such intrusion explains why such Stalinist forcing of the talented is unacceptable whereas the progressive taxation of their income is legitimate. I argue that Cohen's appeal to invasiveness does not adequately capture the moral repugnance of the state's conscripting people into work at a given occupation. I propose that a right to self-ownership, and that which explains such a right, provides a better explanation than Cohen's of why Stalinist forcing is objectionable, whereas progressive taxation is not. 1.

The central role of mathematical modeling in modern evolutionary theory has raised a concern as to why and how abstract formulae can say anything about empirical phenomena of evolution.

The novel account features causal models both as the Humean 'uniform nature' underlying evolutionary induction and as the organizing framework that integrates mathematical and (...) empirical assumptions into a cohesive network of beliefs that functions together to achieve epistemic goals of evolutionary biology.

This article characterizes various species concepts in terms of set-theoretic models that license biological inferences and illustrates the logical connections among different species concepts. Species in this construal are abstract models, rather than biological or even tangible entities, and relate to individual organisms via representation, rather than the membership or mereological whole/part relationship. The proposal sheds new light on vexed issues of species and situates them within broader philosophical contexts of model selection, scientific representation, and scientific realism.

Inequality is intrinsically bad when and because it is unfair. It follows that the ideal of equality is not necessarily realised by a distribution of resources which is envy-free prior to the resolution of risks against which people have an equal opportunity to insure. Even if the upshot of such an ex ante envyfree distribution is just, it is not necessarily fair.

How to Pool Risks across Generations makes the case for the collective provision of pensions, on fair terms of social cooperation. Through the insurance of a mutual association which extends across society and over multiple generations, we share one another's fates by pooling risks across both space and time. Resources are transferred, not simply between different people, but also within the possible future lives of each person: from one's more fortunate to one's less fortunate future selves. The book opens with (...) an investigation of the longevity and investment risk that even a single individual on a desert island would face in providing for her old age. From this atomistic starting point, it builds up, within and across the chapters, to increasingly collective forms of pension provision. By joining together, it is possible to tame the risks we would face as individuals each with our own private pension pot. A collective pension can be justified as a 'social union of social unions': an enduring corporate body, which is formed by agreements to pool risks, in a manner that involves reciprocity between the various individuals that constitute the collective. Even though all individuals age and die, a collective pension scheme remains evergreen, as the average age of members remains relatively unchanged, through the influx of new members to replace those who retire. It is therefore possible to smooth risks indefinitely across as well as within generations, to the mutual advantage of each. (shrink)

Ernst Mayr’s classical work on the nature of causation in biology has had a huge influence on biologists as well as philosophers. Although his distinction between proximate and ultimate causation recently came under criticism from those who emphasize the role of development in evolutionary processes, the formal relationship between these two notions remains elusive. Using causal graph theory, this paper offers a unified framework to systematically translate a given “proximate” causal structure into an “ultimate” evolutionary response, and illustrates evolutionary implications (...) of various kinds of causal mechanisms including epigenetic inheritance, maternal effects, and niche construction. These results not only reveal the essential interplay between proximate and ultimate causation in the study of evolution, but also provide a formal method to evaluate or discover non-standard or yet unknown evolutionary phenomena.

he primary aim of Dworkin's essay is to defend the claim that there are objective moral (and aesthetic or otherwise evaluative) truths against a variety of "external" skeptical challenges. These challenges are "external" because they "offer to justify their skeptical claims -- that these [evaluative] domains cannot provide objective truth -- from premises that are not themselves evaluative."

In a recent review essay of a two volume anthology on left-libertarianism (edited by two of us), Barbara Fried has insightfully laid out most of the core issues that confront left-libertarianism. We are each left-libertarians, and we would like to take this opportunity to address some of the general issues that she raises. We shall focus, as Fried does much of the time, on the question of whether left-libertarianism is a well-defined and distinct alternative to existing forms of liberal egalitarianism. (...) More specifically, we shall address the following fundamental issues raised by Fried (and others): (1) Does the notion self-ownership have any determinate content? (2) What is the relation between self-ownership and world ownership? (3) How is left-libertarianism different from other forms of liberal egalitarianism (e.g., those of Rawls and Dworkin)? (shrink)

Some researchers claim that uncertainty prolongs the duration of emotional experiences because uncertainty toward an emotion-eliciting event prolongs attention to that event. However, some results contradict this claim. We assumed that curiosity rather than uncertainty prolongs the duration of emotional experience via attention, and that attention and emotional experience are prolonged only when uncertainty elicits curiosity. This assumption is based on the information gap theory, which proposes that curiosity increases with uncertainty, but that curiosity decreases at a certain level of (...) uncertainty. We conducted a survey study to investigate the relationships among curiosity, uncertainty, attention and duration of positive and negative emotional experiences. The results showed that curiosity, but not uncertainty, prolonged the duration of emotional experiences and the process was completely mediated by attention both for positive and negative emotions. Moreover, uncertainty prolonged the duration of emotional experiences only when uncertainty elicited curiosity, which in turn prolonged attention to the emotion-eliciting event. (shrink)

In 'Why It Matters that Some Are Worse off than Others,' we offer a new critique of the Priority View. In a recent article, Roger Crisp has argued that our critique is flawed.

We also show that an example that Crisp offers in support of the Priority View in fact lends support to our critique of that view.

In her influential book of _ A Turn to Empire _, J. Pitts argues that Bentham’s project was very different from later British liberal aspiration to civilize the backward countries. On the other hand, Pitts appears to struggle how to treat Bentham’s such description, for instance, of Islamic countries as a region of incurable barbarity and ignorance. I would like to argue that there was no such contradiction as suggested by Pitts in Bentham’s theory. I will firstly (in section 2) (...) discuss Bentham’s 'Place and Time,' and show that, unlike Pitt’s interpretation, Bentham tried to change the religions, traditions and customs of non-Western countries, which are at odds with his principle of utility.

We critically examine Denis Walsh’s latest attack on the causalist view of fitness. Relying on Judea Pearl’s Sure-Thing Principle and geneticist John Gillespie’s model for fitness, Walsh has argued that the causal interpretation of fitness results in a reductio.

Properly understood, the models used by Walsh do not threaten the causalist view of fitness. (shrink)

ABSTRACT I believe that the first correspondence I received from Hillel Steiner was an email in 1998 in which he generously praised a recently-published article of mine and added: ‘I hope it’s not presumptuous of me to say “Welcome to the wonderful world of left-libertarianism!”’ The piece (Otsuka 1998) that prompted this unpresumptuous welcome was left-libertarian in spirit, as it was an attempt to reconcile self-ownership with equality. I was not yet convinced, however, that I was a left-libertarian, so it (...) was not clear at the time whether my exploration of this world was as a curious and sympathetic visitor or as someone who had just begun a period of permanent residency. It turned out to be the latter, and Hillel deserves much of the credit for my settlement in this world that he had himself rediscovered in the 1970s and elegantly reshaped during the past three decades through his essays that lead up to, constitute, and develop and extend his marvellous Essay on Rights (Steiner 1994).
