This book is a collection of eleven essays by one of the most interesting moral philosophers currently writing. It examines challenges to liberal thought posed by the changing circumstances of the modern world such as the conflicting tendencies toward global integration, and greater ethnic and communal identification. The author considers whether liberal principles of justice can accommodate social and global interdependencies while reaffirming the importance of individual responsibility and acknowledging the significance of people's diverse personal and communal allegiances.

We sometimes fail unwittingly to do things that we ought to do. And we are, from time to time, culpable for these unwitting omissions. We provide an outline of a theory of responsibility for unwitting omissions. We emphasize two distinctive ideas: (i) many unwitting omissions can be understood as failures of appropriate vigilance, and; (ii) the sort of self-control implicated in these failures of appropriate vigilance is valuable. We argue that the norms that govern vigilance and the value of self-control (...) explain culpability for unwitting omissions. (shrink)

Philosophical work in the ethics of thought focuses heavily on the ethics of belief, with, in recent years, a particular emphasis on the ways in which we might wrong other people either through our beliefs about them, or our failure to believe what they tell us. Yet in our own lives we often want not merely to be believed, but rather to be understood by others. What does it take to understand another person? In this paper, I provide an account (...) of interpersonal understanding that speaks to this widespread human desire to be understood by others. On the view I defend, to be understood by another person is for them to see our motivating reasons as justifying reasons, whether or not they actually take our reasons to have that normative force. I then provide an explanation of why such understanding is valuable in our lives, which emphasizes how being understood by another person is a way of being more fully with them. (shrink)

In this paper, I examine the connections between bipolar disorder and consent. I defend the view that many (although far from all) individuals with bipolar disorder are competent to consent to a wide variety of things when they are in a manic state.

Theoretical virtues play an important role in the acceptance and belief of theories in science and philosophy. Philosophers have well-developed views on which virtues ought and ought not to influence one’s acceptance and belief. But what do scientists think? This paper presents the results of a quantitative study with scientists from the natural and social sciences and compares their views to those held by philosophers. Some of the more surprising results are: all three groups have a preference order regarding theoretical (...) virtues, making theory choice a much more determinate matter than what has sometimes been suggested; the preference orders are very similar for the three groups; simplicity is viewed as an epistemic virtue particularly by social scientists ; and syntactic parsimony is preferred to ontological parsimony by all three groups.

Variabilism is the view that proper names (like pronouns) are semantically represented as variables. Referential names, like referential pronouns, are assigned their referents by a contextual variable assignment (Kaplan 1989). The reference parameter (like the world of evaluation) may also be shifted by operators in the representation language. Indeed verbs that create hyperintensional contexts, like ‘think’, are treated as operators that simultaneously shift the world and assignment parameters. By contrast, metaphysical modal operators shift the world of assessment only. Names, being (...) variables, refer rigidly in the latter merely intensional contexts, but may vary their reference in hyperintensional contexts. This conforms to the intuition that the content of attitude ascriptions encapsulates referential uncertainty. Furthermore, names in hyperintensional contexts are ambiguous between de re* and de dicto* interpretations. This fact is used to account for asymmetric mistaken identity attributions (for example, Biron thinks Katherine is Rosaline, but he doesn’t think Rosaline is Katherine). -/- The variable theory compares favourably with its alternatives, including Millianism and descriptivism. Millians cannot account for the behaviour of names in hyperintensional contexts, while descriptivists cannot generate a necessary contrast between intensional and hyperintensional contexts. No other theory can capture the facts pertaining to the existentially bound use of names. (shrink)

This paper examines the interplay of semantics and pragmatics within the domain of film. Films are made up of individual shots strung together in sequences over time. Though each shot is disconnected from the next, combinations of shots still convey coherent stories that take place in continuous space and time. How is this possible? The semantic view of film holds that film coherence is achieved in part through a kind of film language, a set of conventions which govern the relationships (...) between shots. In this paper, we develop and defend a new version of the semantic view. We articulate it for a pair of conventions that govern spatial relations between viewpoints. One such rule is already well-known; sometimes called the "180° Rule," we term it the X-Constraint; to this we add a previously unrecorded rule, the T-Constraint. As we show, both have the effect, in different ways, of limiting the way that viewpoint can shift through space from shot to shot over the course of a film sequence. Such constraints, we contend, are analogous to relations of discourse coherence that are widely recognized in the linguistic domain. If film is to have a language, it is a language made up of rules like these. (shrink)

Actors, undercover investigators, and readers of fiction sometimes report “losing themselves” in the characters they imitate or read about. They speak of “taking on” or “assuming” the beliefs, thoughts, and feelings of someone else. I offer an account of this strange but familiar phenomenon—what I call imaginative transportation.

Much attention has been paid to moral understanding as an individual achievement, when a single agent gains insight into distinctly moral matters. Crucially overlooked, I argue, is the phenomenon of shared moral understanding, when you and I understand moral matters together, in a way that can’t be reduced to each of us having moral understanding on our own. My argument pays close attention to two central moral practices: justifying our actions to others, and apologizing for wrongdoing. I argue that, whenever (...) I owe you a justification or an apology, I thereby owe it to you to aim at our coming to a shared moral understanding. My argument has two upshots. The first is a novel explanation of the importance of moral understanding in our lives, one that emphasizes the importance of understanding moral reasons together. The second is a better understanding of the very obligations involved in two of our most central interpersonal moral practices. (shrink)

Johnson, Bernard Williams, Peter Railton, Amartya Sen, Philippa Foot, and Derek Parfit-- debate arguments for and against the moral doctrine of consequentialism to present a complete view of this important topic in moral philosophy.

Mind wandering is a pervasive feature of subjective experience. But why does the mind tend to wriggle about rather than always staying focused? To answer this question, this paper defends the claim that mind wandering consists in task-unrelated thought. Despite being the standard view of mind wandering in cognitive psychology, there has been no systematic elaboration or defense of the task-unrelated thought view of mind wandering. Here, I argue for the task-unrelated thought view by showing how mind wandering reflects a (...) distinctive form of non-vigilant thinking. When the relationship between mind wandering and vigilance is clarified, several objections to the task-unrelated thought view can be defused. Not only does this provide a novel defense of the task-unrelated thought view of mind wandering, but it also presents an account of mind wandering that is compatible with a naturalistic account of subjectivity.

Suppose that a patient is receiving treatment options from her doctor. In one case, the doctor says, “the surgery has a 90% survival rate.” Now, suppose the doctor instead said, “the procedure has a 10% mortality rate.” Predictably, the patient is more likely to consent on the first description and more likely to dissent on the second. This is an example of a framing effect. A framing effect occurs when “the description of [logically-equivalent] options in terms of gains (positive frame) (...) rather than losses (negative frame) elicits systematically different choices.” Framing effects are ubiquitous, but they are particularly troublesome in medicine. Many worry that there is tension between valuing informed consent and using framing effects in clinical settings. In this paper, I answer this question: if an individual is subject to a framing effect when she gives her consent, does this undermine the validity of her consent? I argue that framing effects do not undermine consent in general. (shrink)

Because moral understanding involves a distinctly first-personal grasp of moral matters, there is a temptation to think of its value primarily in terms of achievements that reflect well on its possessor: the moral worth of one's action or the virtue of one's character. These explanations, I argue, do not do full justice to the importance of moral understanding in our moral lives. Of equal importance is the value of moral understanding in our relations with other moral agents. In particular, I (...) argue that an understanding of moral matters is of central importance within relations of solidarity. In addition to highlighting an overlooked aspect of moral understanding's value, this view also has important implications for what solidarity requires of those who stand in that relationship.

Much current debate in the metaphysics of time is between A-theorists and B-theorists. Central to this debate is the assumption that time exists and that the task of metaphysics is to catalogue time’s features. Relatively little consideration has been given to an error theory about time. Since there is very little extant work on temporal error theory the goal of this paper is simply to lay the groundwork to allow future discussion of the relative merits of such a view. The (...) paper thus develops a conceptual framework from within which to evaluate claims about the actual existence, or not, of temporality as that notion appears in folk discourses about time, and from there to examine claims about the counterfactual existence, or not, of temporality so conceived. We subsequently apply this framework to three extant positions drawn from physics and metaphysics that deny the existence of time. We show that only one of these positions is a folk temporal error theory; that is, a view that denies the existence of time as that notion is operative in our everyday thought and talk. (shrink)

Liberalism generally holds that legitimate political power is limited and is to be impartially exercised, only for the public good. Liberals accordingly assign political priority to maintaining certain basic liberties and equality of opportunities; they advocate an essential role for markets in economic activity, and they recognize government's crucial role in correcting market breakdowns and providing public goods. Classical liberalism and what I call “the high liberal tradition” are two main branches of liberalism. Classical liberalism evolved from the works of (...) Adam Smith and the classical utilitarian economists; its major 20th century representatives include Friedrich Hayek and Milton Friedman. The high liberal tradition developed from John Stuart Mill's works, and its major philosophical representatives in the 20th century are John Dewey and, later, John Rawls. This paper discusses the main distinguishing features of the classical and the high liberal traditions and their respective positions regarding capitalism as an economic and social system. Classical liberals, unlike high liberals, regard economic liberties and rights of private property in productive resources to be nearly as important as basic liberties. They conceive of equality of opportunity in more formal terms, and regard capitalist markets and the price system as essential not only to the allocation of production resources, but also as the fundamental criterion for the just distribution of income, wealth, and economic powers. High liberals, by contrast, regard the economic liberties as subordinate to the exercise of personal and civic liberties. They are prepared to regulate and restrict economic liberties to achieve greater equality of opportunities, reduce inequalities of economic powers, and promote a broader conception of the public good. And while high liberals endorse markets and the price system as essential to allocation of productive resources, they do not regard markets as the fundamental criterion for assessing just distributions of income, wealth, and economic powers and positions of responsibility. The paper concludes with some reflections upon the essential role that dissimilar conceptions of persons and society play in grounding the different positions on economic justice that classical and high liberals advocate.

In response to the spread of COVID-19, governments across the world have, with very few exceptions, enacted sweeping restrictive lockdown policies that impede citizens’ freedom to move, work, and assemble. This paper critically responds to the central arguments for restrictive lockdown legislation. We build our critique on the following assumption: public policy that enjoys virtually unanimous support worldwide should be justified by uncontroversial moral principles. We argue that that the virtually unanimous support in favor of restrictive lockdowns is not adequately (...) justified by the arguments given in favor of them. Importantly, this is not to say that states ought not impose restrictive lockdown measures, but rather that the extent of the acceptance of these measures is not proportionate to the strength of the arguments for lockdowns. -/- We begin by exploring the case for restrictive lockdowns. We first argue that several of the principles that are used to justify the lockdowns yield unexpectedly revisionary implications for other political problems that many would be unwilling to accept. We then outline what we consider the strongest argument for a lockdown—namely, that its net welfare benefits are great enough to defeat the moral presumption against restricting citizens’ civil liberties to move, work, and assemble. However, we give a number of reasons for doubting that the lockdown’s net welfare benefits are, in fact, sufficiently high to defeat the presumption against it. (shrink)

What if "liberal democracy" were a contradiction in terms? This book distinguishes liberalism from democracy to defend a Rancirean vision of impure politics. Disclosing Rancire's refusal of ontology as political, The Lessons of Rancire enacts a critical theory beyond unmasking and a democratic politics beyond liberalism.

I argue that metaethicists should be concerned with two kinds of alienation that can result from theories of normativity: alienation between an agent and her reasons, and alienation between an agent and the concrete others with whom morality is principally concerned. A theory that cannot avoid alienation risks failing to make sense of central features of our experience of being agents, in whose lives normativity plays an important role. The twin threats of alienation establish two desiderata for theories of normativity; (...) however, I argue that they are difficult to jointly satisfy. (shrink)

The Generality Problem is widely recognized to be a serious problem for reliabilist theories of justification. James R. Beebe's Statistical Solution is one of only a handful of attempted solutions that has garnered serious attention in the literature. In their recent response to Beebe, Julien Dutant and Erik J. Olsson successfully refute Beebe's Statistical Solution. This paper presents a New Statistical Solution that countenances Dutant and Olsson's objections, dodges the serious problems that trouble rival solutions, and retains the theoretical virtues (...) that made Beebe's solution so attractive in the first place. There indeed exists a principled, rigorous, conceptually sparse, and plausible solution to the Generality Problem: it is the New Statistical Solution. (shrink)

At the core of Kant's ethics lies the claim that if there is a supreme principle of morality then it cannot be a principle based on utilitarianism or Aristotelian perfectionism or the Ten Commandments. The only viable candidate for such a principle is the categorical imperative. This book is the most detailed investigation of this claim. It constructs a new, criterial reading of Kant's derivation of one version of the categorical imperative: the Formula of Universal Law. This reading shows this (...) derivation to be far more compelling than contemporary philosophers tend to believe. It also reveals a novel approach to deriving another version of the categorical imperative, the Formula of Humanity, a principle widely considered to be the most attractive Kantian candidate for the supreme principle of morality. This book will be important not just for Kant scholars but for a broad swathe of students of philosophy. (shrink)

Philosophers have become newly interested in the ethics of sex. One promising feature of this new discussion is that it has been broadening our moral lens to include individuals whose sexual interests have historically been denied or ignored. One such group is the elderly. Contrary to popular belief, many elderly people want to have sex and see it as a regular part of their lives. If society harbors ignorance about or prejudice against elderly sexuality, it harbors stronger views against the (...) sexual expression of elderly people with dementia. People with dementia are often prohibited by nursing‐home staff, sometimes in extreme ways, from having sex with their partners. This prohibition is at least partly motivated by the goal of protecting the vulnerable. However, cutting people with dementia off from sex has negative health effects and is a needless restriction of their autonomy. In this article, I argue that the expanding moral lens in sexual ethics should include the sexual expression of elderly individuals with dementia and that their sexual expression should be respected. Specifically, I argue that many people with dementia are competent to consent to sexual activity with their long‐term partners. (shrink)

In recent years, the number of studies examining mind wandering has increased considerably, and research on the topic has spread widely across various domains of psychological research. Although the term “mind wandering” has been used to refer to various cognitive states, researchers typically operationalize mind wandering in terms of “task-unrelated thought” (TUT). Research on TUT has shed light on the various task features that require people’s attention, and on the consequences of task inattention. Important methodological and conceptual complications do persist, (...) however, in current investigations of TUT. As we argue, these complications may be dampening the development of a more nuanced scientific account of TUT. Here, we outline three of the more prominent methodological and conceptual complications in the literature on TUT, and we discuss potential directions for researchers to take as they move forward in their investigations of TUT.

There was a consensus in late Scholasticism that evils are privations, the lacks of appropriate perfections. For something to be evil is for it to lack an excellence that, by its nature, it ought to have. This widely accepted ontology of evil was used, in part, to help explain the source of evil in a world created and sustained by a perfect being. during the second half of the seventeenth century, progressive early moderns began to criticize the traditional privative account (...) of evil on a variety of philosophical and theological grounds. Embedded in Scholastic Aristotelianism and applied to problems of evil, privation theory seemed to some like yet another instance of pre-modern pseudo-explanation.1Against this .. (shrink)

Are the real numbers rich enough to measure intelligence? We generalize a result of Alexander and Hutter about the so-called Legg-Hutter intelligence measures of reinforcement learning agents. Using the generalized result, we exhibit a paradox: in one particular version of the Legg-Hutter intelligence measure, certain agents all have intelligence 0, even though in a certain sense some of them outperform others. We show that this paradox disappears if we vary the Legg-Hutter intelligence measure to be hyperreal-valued rather than real-valued.

The partiality we display, in so far as we form and sustain personal attachments, is not normatively fundamental. It is a by-product of the deference and responsiveness that are essential to our engagement with the world. We cannot form and sustain valuable personal relationships without seeing ourselves as answerable to the other participants in those relationships. And we cannot develop and sustain valuable projects without responding to the constraints imposed on our activities by the nature and requirements of those projects (...) themselves. More generally, we cannot engage with the world without responding differentially—or displaying partiality—with respect to the objects of our engagement. Partiality is thus a by-product of engagement. We cannot engage with the world at all without exhibiting forms of partiality. (shrink)

One popular theory of moral responsibility locates responsible agency in exercises of control. These control-based theories often appeal to tracing to explain responsibility in cases where some agent is intuitively responsible for bringing about some outcome despite lacking direct control over that outcome’s obtaining. Some question whether control-based theories are committed to utilizing tracing to explain responsibility in certain cases. I argue that reflecting on certain kinds of negligence shows that tracing plays an ineliminable role in any adequate control-based theory (...) of responsibility. (shrink)

Cosmopolitans argue that the account of human rights and distributive justice in John Rawls's The Law of Peoples is incompatible with his argument for liberal justice. Rawls should extend his account of liberal basic liberties and the guarantees of distributive justice to apply to the world at large. This essay defends Rawls's grounding of political justice in social cooperation. The Law of Peoples is drawn up to provide principles of foreign policy for liberal peoples. Human rights are among the necessary (...) conditions for social cooperation, and so long as a decent people respect human rights, a common good, and the Law of Peoples, it is not the role of liberal peoples to impose upon well-ordered decent peoples liberal liberties they cannot endorse. Moreover, the difference principle is not an allocative or alleviatory principle, but applies to design property and other basic social institutions necessary to economic production, exchange and consumption. It presupposes political cooperation—a legislative body to actively apply it, and a legal system to apply it to. There is no feasible global state or global legal system that could serve these roles. Finally, the difference principle embodies a conception of democratic reciprocity that is only appropriate to cooperation among free and equal citizens who are socially productive and politically autonomous. a Footnotesa I am grateful to K. C. Tan for many helpful discussions and criticisms of this essay.

There is an old meta-philosophical worry: very roughly, metaphysical theories have no observational consequences and so the study of metaphysics has no value. The worry has been around in some form since the rise of logical positivism in the early twentieth century but has seen a bit of a renaissance recently. In this paper, I provide an apology for metaphysics in the face of this kind of concern. The core of the argument is this: pure mathematics detaches from science in (...) much the same manner as metaphysics and yet it is valuable nonetheless. The source of value enjoyed by pure mathematics extends to metaphysics as well. Accordingly, if one denies that metaphysics has value, then one is forced to deny that pure mathematics has value. The argument places an added burden on the sceptic of metaphysics. If one truly believes that metaphysics is worthless (as some philosophers do), then one must give up on pure mathematics as well.

In the Formula of Humanity, Kant embraces the principle that it is wrong for us to treat others merely as means. For contemporary Kantian ethicists, this Mere Means Principle plays the role of a moral constraint: it limits what we may do, even in the service of promoting the overall good. But substantive interpretations of the principle generate implausible results in relatively ordinary cases. On one interpretation, for example, you treat your opponent in a tennis tournament merely as a means (...) and thus wrongly when you try, through defeating him, to win first place. The article aims to develop a reconstruction of the Mere Means Principle that has more plausible implications than do rival reconstructions. It sets out a sufficient condition for an agent's treating another merely as a means. This condition is intended to be Kantian, but not necessarily one that Kant endorses. (shrink)

Objects of Metaphor puts forward a philosophical account of metaphor radically different from those currently on offer. Powerful and flexible enough to cope with the syntactic complexity typical of genuine metaphor, it offers novel conceptions of the relationship between simile and metaphor, the notion of dead metaphor, and the idea of metaphor as a robust theoretic kind. Without denying that metaphor can sometimes be merely ornamental, Guttenplan justifies the view of metaphor as fundamental to language and the study of language. (...) His book will be of great interest not only to philosophers in this field, but also to those working across psychology and linguistics. (shrink)

Cook and Reckhow defined a propositional formulation of the pigeonhole principle. This paper shows that there are Frege proofs of this propositional pigeonhole principle of polynomial size. This together with a result of Haken gives another proof of Urquhart's theorem that Frege systems have an exponential speedup over resolution. We also discuss connections to provability in theories of bounded arithmetic.

This article draws on the moral philosophy of Immanuel Kant to explore whether a corporate ‘duty of beneficence’ to non-shareholders is consistent with the orthodox ‘shareholder theory’ of the firm. It examines the ethical framework of Milton Friedman’s argument and asks whether it necessarily rules out the well-being of non-shareholders as a corporate objective. The article examines Kant’s distinction between ‘duties of right’ and ‘duties of virtue’ (the latter including the duty of beneficence) and investigates their consistency with the shareholder (...) theory. The article concludes that it is possible within the ethical framework of shareholder theory for managers to pursue directly the happiness of non-shareholders. Furthermore, shareholders have a duty to hold management to account for the moral consequences of the firm’s activities on non-shareholding stakeholders. (shrink)

The threat of bioterrorism, the emergence of the SARS epidemic, and a recent focus on professionalism among physicians, present a timely opportunity for a review of, and renewed commitment to, physician obligations to care for patients during epidemics. The professional obligation to care for contagious patients is part of a larger "duty to treat," which historically became accepted when 1) a risk of nosocomial infection was perceived, 2) an organized professional body existed to promote the duty, and 3) the public (...) came to rely on the duty. Physicians' responses to epidemics from the Hippocratic era to the present suggests an evolving acceptance of the professional duty to treat contagious patients, reaching a long-held peak between 1847 and the1950's. There has been some professional retrenchment against this duty to treat in the last 40 years but, we argue, conditions favoring acceptance of the duty are met today. A renewed embrace of physicians' duty to treat patients during epidemics, despite conditions of personal risk, might strengthen medicine's relationship with society, improve society's capacity to prepare for threats such as bioterrorism and new epidemics, and contribute to the development of a more robust and meaningful medical professionalism.

I argue that high level causal relationships are often more fundamental than low level causal relationships. My argument is based on some general principles governing when one causal relationship will metaphysically ground another—a phenomenon I term derivative causation. These principles are in turn based partly on our intuitive judgments concerning derivative causation in a series of representative examples, and partly on some powerful theoretical considerations in their favour. I show how these principles entail that low level causation can derive from (...) high level causation, and in particular that neural causation can derive from mental causation. I then draw out several important consequences of this result. Most immediate among these are the implications the result has for aspirations to reduce high level causation to its low level counterpart. But the result also bears on the possibility of downward causation, the relationship between counterfactuals and causation, and the idea—familiar from both the literature on the exclusion problem and the literature on proportionality constraints on causation—that causal relationships at different levels compete for their existence.

We consider two reasons why firms should be owned and run democratically by their workers. The first concerns accountability : Because the employment relationship involves the exercise of power, its governance should on democratic grounds be accountable to those most directly affected. The second concerns efficiency : The democratic firm uses a lower level of inputs per unit of output than the analogous capitalist firm.

This paper proposes a refocusing of consent for clinical genetic testing, moving away from an emphasis on autonomy and information provision, towards an emphasis on the virtues of healthcare professionals seeking consent, and the relationships they construct with their patients. We draw on focus groups with UK healthcare professionals working in the field of clinical genetics, as well as in-depth interviews with patients who have sought genetic testing in the UK’s National Health Service. We explore two aspects of consent: first, (...) how healthcare professionals consider the act of ‘consenting’ patients; and second how these professional accounts, along with the accounts of patients, deepen our understanding of the consent process. Our findings suggest that while healthcare professionals working in genetic medicine put much effort into ensuring patients’ understanding about their impending genetic test, they acknowledge, and we show, that patients can still leave genetic consultations relatively uninformed. Moreover, we show how placing emphasis on the informational aspect of genetic testing is not always reflective of, or valuable to, patients’ decision-making. Rather, decision-making is socially contextualised – also based on factors outside of information provision. A more collaborative on-going consent process, grounded in virtue ethics and values of honesty, openness and trustworthiness, is proposed. (shrink)

In this two-part series, I explore some of the most important and influential interpretations of Spinoza as an idealist. In this second part, I turn to more recent idealistic interpretations of Spinoza, including the important British idealist school (including Pollock, Martineau, Joachim, and John Caird) at the turn of the 20th century to a very recent and important kind of idealist reading found in the work of Michael Della Rocca.

This paper is an attempt to lay out a meta‐ethical position that is inspired by the framework of Wittgenstein's later philosophy. To achieve this goal, this paper is divided into two parts. First, I explore recent attempts to tie Wittgenstein's epistemology in On Certainty to moral epistemology. I argue that there can be a meaningful parallel drawn between the epistemic certainties discussed in On Certainty and what I consider to be moral certainties. These moral certainties are unjustified fundamental moral attitudes (...) that underlie our moral practices. Then, I show how the debate over moral certainty has branched into two directions. One direction presents the concept of moral certainty as a naturalistic concept. On this reading, moral certainties transcend time and place since they are rooted in our natural tendencies to act or not act in certain ways. The other direction presents moral certainty as a distinctly relativistic concept. On this reading, we have our moral certainties because we belong to communities that agree on these certainties. In the second section, I argue that we have both natural, universal certainties and localized, relative certainties. I also argue that our localized certainties are constrained by non‐moral facts about ourselves and about the world. To make this argument, I rely on Wittgenstein's concept of “general facts of nature.” The result of the paper is a meta‐ethical position that can be located in between moral relativism and moral realism.

Can an AGI create a more intelligent AGI? Under idealized assumptions, for a certain theoretical type of intelligence, our answer is: “Not without outside help”. This is a paper on the mathematical structure of AGI populations when parent AGIs create child AGIs. We argue that such populations satisfy a certain biological law. Motivated by observations of sexual reproduction in seemingly-asexual species, the Knight-Darwin Law states that it is impossible for one organism to asexually produce another, which asexually produces another, and (...) so on forever: that any sequence of organisms (each one a child of the previous) must contain occasional multi-parent organisms, or must terminate. By proving that a certain measure (arguably an intelligence measure) decreases when an idealized parent AGI single-handedly creates a child AGI, we argue that a similar Law holds for AGIs. (shrink)
