유교의 화이지변과 왕도사상을 핵심으로 하는 ‘천하질서’ 담론은 사실상 ‘지배의 정당성’의 문제이기도 하다. 중국 모델이 아직 그 형체를 분명히 드러내지 않은 상황에서 ‘천하질서’가 중국에서 뜨거운 담론이 되고 있는 것은 이것이 사실상 ‘지배의 정당성’이라는 문제와 밀접하게 관련이 있기 때문이다. 그렇다면 여기서 ‘지배의 정당성’을 어떻게 이해해야 하는가. 21세기라는 현시점에서 ‘지배의 정당성’이란 결국 유교의 보편성의 재구성 속에서 분열이 아닌 통합의 제국적 메카니즘을 확보하는 것이다.BR이 글은 ‘대륙신유가’라는 학문집단이 ‘신캉유웨이주의’를 매개로 하여 시도하는 천하질서와 유교적 보편주의의 재구성의 가능성을 타진하고자 하는 기초적 작업이다. 그 초점은 두가지이다. 하나는 현실적인 (...) 문제로, 이들이 캉유웨이가 문제로 삼았던 중국강역의 보전과 ‘문명중국’의 회복이라는 문제에서 그 정당화전략을 설득력 있게 짜고 있는가이다. 동중서(董仲舒)는 천하사상에 의한 ‘지배의 정당성’ 탄생의 사이클을 완성함으로써 유교를 내용으로 하는 제국의 통치원리를 탄생시켰다. 동중서가 유교를 내용으로 하는 제국의 통치원리를 완성한 이후 유교는 종족보다는 보편의 계기로 받아들여졌다. 유교는 이후 종족보다는 국가(제국)에 내속되었다. “중국에서 ‘지배의 정당성’은 지배자의 민족적 출신으로 판단하는 것이 아니고 ‘대일통’을 실현한 왕조야말로 ‘정통’의 중화왕조라고 하는 사고방식은 이 때부터 보편화되었다. 모든 중화왕조가 목숨을 걸고 제국적 구조를 구축하여 중화제국으로 변신하려 노력한 이유도 천하사상 즉 ‘대일통’의 사상의 틀로 자신의 정당성이 확보될 수 있었기 때문이다. 캉유웨이가 100년 전에 고민한 이 문제는 지금의 중국에도 그대로 존재한다. 그러나 이 문제는 주변에 대한 차별관계의 청산, 대등한 협력 관계의 구축이라는 21세기적 발상의 전환 없이는 실현 불가능하다.BR다른 하나는 규범적 문제로, 천하질서와 유교적 보편주의의 재구성이라는 작업을 통해 ‘성찰적 유학’을 보여줄 수 있는가의 여부이다. ‘성찰적 유학’의 두가지 조건은 타자성과 윤리성이다. 이두 조건이 결여된 신유학 논의는 ‘봉건’으로의 자기회귀라는 비난을 받을 수 있으며 이 형태로는 중국의 안과 밖을 설득시킬 수가 없다. 더 나아가 이들의 기획은 또 다른 ‘중국중심주의’를 꽤하려는 것이라는 오해를 피할 수 없다. 중국의 유학이 재보편화하기 위해서는 서양이라는 타향을 표류하고 난 이후 다시 고향에 돌아온 상태에서 이제 다시금 ‘나는 누구인가’, ‘나의 가치는 어디에 있는가’라는 질문을 낯설게 해야 한다. 그랬을 때 자기에 대한 진정한 객관화과정이 시작될 수 있으며 자기상대화를 통한 타자성을 확보할 수 있다. 이 과정을 거쳐야만 ‘성찰적 유학’이라 칭할 수 있으며 ‘지속가능성’을 말할 수 있다. 이를 기준으로 본다면 ‘대륙신유가’의 ‘신캉유웨이주의’를 통한 천하질서와 유교적 보편주의의 재구성의 가능성은 지켜봐야 하겠지만 그렇게 높다고 할 수 없다. 현실적 문제든 규범적 문제든 재구성의 가능성이 높지 않다면 그것은 아마 20세기를 거친 21세기적 인식의 부재에서 비롯된 것일 가능성이 높다.

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies we can take today to safeguard humanity’s future. (shrink)

It is often claimed that from the moment of conception embryos have the same moral status as adult humans. This claim plays a central role in many arguments against abortion, in vitro fertilization, and stem cell research. In what follows, I show that this claim leads directly to an unexpected and unwelcome conclusion: that natural embryo loss is one of the greatest problems of our time and that we must do almost everything in our power to prevent it. I examine (...) the responses available to those who hold that embryos have full moral status and conclude that they cannot avoid the force of this argument without giving up this key claim.

This paper surveys a wide range of proposed hypermachines, examining the resources that they require and the capabilities that they possess. 2005 Elsevier Inc. All rights reserved.

The diagonal method is often used to show that Turing machines cannot solve their own halting problem. There have been several recent attempts to show that this method also exposes either contradiction or arbitrariness in other theoretical models of computation which claim to be able to solve the halting problem for Turing machines. We show that such arguments are flawed—a contradiction only occurs if a type of machine can compute its own diagonal function. We then demonstrate why such a situation (...) does not occur for the methods of hypercomputation under attack, and why it is unlikely to occur for any other serious methods. Introduction Issues with specific hypermachines Conclusions for hypercomputation. (shrink)

An exploration of mathematical style through 99 different proofs of the same theorem This book offers a multifaceted perspective on mathematics by demonstrating 99 different proofs of the same theorem. Each chapter solves an otherwise unremarkable equation in distinct historical, formal, and imaginative styles that range from Medieval, Topological, and Doggerel to Chromatic, Electrostatic, and Psychedelic. With a rare blend of humor and scholarly aplomb, Philip Ording weaves these variations into an accessible and wide-ranging narrative on the nature and practice (...) of mathematics. Inspired by the experiments of the Paris-based writing group known as the Oulipo—whose members included Raymond Queneau, Italo Calvino, and Marcel Duchamp—Ording explores new ways to examine the aesthetic possibilities of mathematical activity. 99 Variations on a Proof is a mathematical take on Queneau’s Exercises in Style, a collection of 99 retellings of the same story, and it draws unexpected connections to everything from mysticism and technology to architecture and sign language. Through diagrams, found material, and other imagery, Ording illustrates the flexibility and creative potential of mathematics despite its reputation for precision and rigor. Readers will gain not only a bird’s-eye view of the discipline and its major branches but also new insights into its historical, philosophical, and cultural nuances. Readers, no matter their level of expertise, will discover in these proofs and accompanying commentary surprising new aspects of the mathematical landscape. (shrink)

How should we make decisions when we're uncertain about what we ought, morally, to do? Decision-making in the face of fundamental moral uncertainty is underexplored terrain: MacAskill, Bykvist, and Ord argue that there are distinctive norms by which it is governed, and which depend on the nature of one's moral beliefs.

It is often said that there are three great traditions of normative ethics: consequentialism, deontology and virtue ethics. Each is based around a compelling intuition about the nature of ethics: that what is ultimately important is that we produce the best possible outcome, that ethics is a system of rules which govern our behaviour, and that ethics is about living a life that instantiates the virtues, such as honesty, compassion and loyalty. This essay is about how best to interpret consequentialism. (...) I show that if we take consequentialism beyond the assessment of acts, using a consequentialist criterion to assess decision making, motivation, and character, then the resulting theory can also capture many of the intuitions about systems of moral rules and excellences of character that lead people to deontology and virtue ethics. I begin by considering the argument that consequentialism is self-defeating because its adoption would produce bad outcomes. I take up the response offered by the classical utilitarians: when properly construed, consequentialism does not require us to make our decisions by a form of naïve calculation, or to be motivated purely by universal benevolence. Instead it requires us to use the decision procedure that will produce the best outcome and to have the motives that lead to the best outcome. I take this idea as my starting point, and spend the thesis developing it and considering its implications. I demonstrate that neither act-consequentialism nor rule-consequentialism has the resources to adequately assess decision making and motivation. I therefore turn to the idea of global consequentialism, which assesses everything in terms of its consequences. I then spend the greater part of the essay exploring how best to set up such a theory and how best to apply it to decision making and motivation. I overcome some important objections to the approach, and conclude by showing how the resulting approach to consequentialism helps to bridge the divide between the three traditions. (shrink)

We show how to determine the k-th bit of Chaitin’s algorithmically random real number Ω by solving k instances of the halting problem. From this we then reduce the problem of determining the k-th bit of Ω to determining whether a certain Diophantine equation with two parameters, k and N , has solutions for an odd or an even number of values of N . We also demonstrate two further examples of Ω in number theory: an exponential Diophantine equation with (...) a parameter k which has an odd number of solutions iff the k-th bit of Ω is 1, and a polynomial of positive integer variables and a parameter k that takes on an odd number of positive values iff the k-th bit of Ω is 1. (shrink)

We present a new method for expressing Chaitin’s random real, Ω, through Diophantine equations. Where Chaitin’s method causes a particular quantity to express the bits of Ω by fluctuating between finite and infinite values, in our method this quantity is always finite and the bits of Ω are expressed in its fluctuations between odd and even values, allowing for some interesting developments. We then use exponential Diophantine equations to simplify this result and finally show how both methods can also be (...) used to create polynomials which express the bits of Ω in the number of positive values they assume.

Consequentialism is often charged with being self-defeating, for if a person attempts to apply it, she may quite predictably produce worse outcomes than if she applied some other moral theory. Many consequentialists have replied that this criticism rests on a false assumption, confusing consequentialism’s criterion of the rightness of an act with its position on decision procedures. Consequentialism, on this view, does not dictate that we should be always calculating which of the available acts leads to the most good, but (...) instead advises us to decide what to do in whichever manner it is that will lead to the best outcome. Whilst it is typically afforded only a small note in any text on consequentialism, this reply has deep implications for the practical application of consequentialism, perhaps entailing that a consequentialist should eschew calculation altogether.

– We present a new paradigm extending the Iterated Prisoner's Dilemma to multiple players. Our model is unique in granting players information about past interactions between all pairs of players – allowing for much more sophisticated social behaviour. We provide an overview of preliminary results and discuss the implications in terms of the evolutionary dynamics of strategies.

This paper argues in favor of a particular account of decision‐making under normative uncertainty: that, when it is possible to do so, one should maximize expected choice‐worthiness. Though this position has been often suggested in the literature and is often taken to be the ‘default’ view, it has so far received little in the way of positive argument in its favor. After dealing with some preliminaries and giving the basic motivation for taking normative uncertainty into account in our decision‐making, we (...) consider and provide new arguments against two rival accounts that have been offered—the accounts that we call ‘My Favorite Theory’ and ‘My Favorite Option’. We then give a novel argument for comparativism—the view that, under normative uncertainty, one should take into account both probabilities of different theories and magnitudes of choice‐worthiness. Finally, we further argue in favor of maximizing expected choice‐worthiness and consider and respond to five objections. (shrink)

Suppose that we develop a medically safe and affordable means of enhancing human intelligence. For concreteness, we shall assume that the technology is genetic engineering (either somatic or germ line), although the argument we will present does not depend on the technological implementation. For simplicity, we shall speak of enhancing “intelligence” or “cognitive capacity,” but we do not presuppose that intelligence is best conceived of as a unitary attribute. Our considerations could be applied to specific cognitive abilities such as verbal (...) fluency, memory, abstract reasoning, social intelligence, spatial cognition, numerical ability, or musical talent. It will emerge that the form of argument that we use can be applied much more generally to help assess other kinds of enhancement technologies as well as other kinds of reform. However, to give a detailed illustration of how the argument form works, we will focus on the prospect of cognitive enhancement. (shrink)

In this report I provide an introduction to the burgeoning field of hypercomputation – the study of machines that can compute more than Turing machines. I take an extensive survey of many of the key concepts in the field, tying together the disparate ideas and presenting them in a structure which allows comparisons of the many approaches and results. To this I add several new results and draw out some interesting consequences of hypercomputation for several different disciplines.

Prioritarianism is the moral view that a fixed improvement in someone's well-being matters more the worse off they are. Its supporters argue that it best captures our intuitions about unequal distributions of well-being. I show that prioritarianism sometimes recommends acts that will make things more unequal while simultaneously lowering the total well-being and making things worse for everyone ex ante. Intuitively, there is little to recommend such acts and I take this to be a serious counterexample for prioritarianism.

If people have different resources, tastes, or needs, they may be able to exchange goods or services such that they each feel they have been made better off. This is trade. If people have different moral views, then there is another type of trade that is possible: they can exchange goods or services such that both parties feel that the world is a better place or that their moral obligations are better satisfied. We can call this moral trade. I introduce (...) the idea of moral trade and explore several important theoretical and practical implications. (shrink)

Given the deep disagreement surrounding population axiology, one should remain uncertain about which theory is best. However, this uncertainty need not leave one neutral about which acts are better or worse. We show that, as the number of lives at stake grows, the Expected Moral Value approach to axiological uncertainty systematically pushes one toward choosing the option preferred by the Total View and critical-level views, even if one’s credence in those theories is low.

Some risks have extremely high stakes. For example, a worldwide pandemic or asteroid impact could potentially kill more than a billion people. Comfortingly, scientific calculations often put very low probabilities on the occurrence of such catastrophes. In this paper, we argue that there are important new methodological problems which arise when assessing global catastrophic risks and we focus on a problem regarding probability estimation. When an expert provides a calculation of the probability of an outcome, they are really providing the (...) probability of the outcome occurring, given that their argument is watertight. However, their argument may fail for a number of reasons such as a flaw in the underlying theory, a flaw in the modeling of the problem, or a mistake in the calculations. If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect. We develop this idea formally, explaining how it differs from the related distinctions of model and parameter uncertainty. Using the risk estimates from the Large Hadron Collider as a test case, we show how serious the problem can be when it comes to catastrophic risks and how best to address it. (shrink)

L’influence de Pierre Poiret sur le milieu piétiste en Allemagne est très hétérogène. Il a lui-même découvert les idées d’Antoinette Bourignon à Francfort et s’est chargé de diffuser ses enseignements à travers les groupes piétistes, notamment les « piétistes radicaux ». Les idées millénaristes de J. W. et J. E. Petersen sont assez comparables à celles de Poiret. La Kirchen- und Ketzerhistorie de G. Arnold a mieux fait connaître l’importance de Poiret à propos du franchissement des frontières entre les confessions (...) religieuses. Les piétistes du Wurtemberg comme J. A. Bengel et Chr. F. Oetinger ont été influencés par le projet théologique de Poiret tel qu’il est esquissé dans l’Œconomie divine. Dans l’orphelinat de Halle, les écrits de Poiret sont publiés par A. H. Francke et A. W. Böhme. En même temps, Poiret est fortement critiqué par Ph. J. Spener, J. W. Jäger et J. Lange. Il fait enfin connaître la piété mystique par les biographies de plusieurs auteurs mystiques de la fin du Moyen Âge. Via G. Tersteegen, ces biographies sont mieux connues en Allemagne. Les dirigeants du mouvement de réveil (catholique) de l’Allgäu (début du XIXe siècle) ainsi que Hedwig von Redern, écrivain de la Gemeinschaftsbewegung (fin du XIXe siècle) ont repris ces biographies mystiques dans leur enseignement de la vie pieuse.

Many of the commentaries have made similar points regarding the nature of full moral status, so I shall begin by addressing these together. They argue that my representation of the Claim is stronger than many proponents of full moral status would accept (Ord 2008). Robert Card (2008) says that I assume that it is equally bad to lose human life at all stages. Russell DiSilvestro (2008) says that I assume a flawed principle that he calls (M). Marianne Burda (2008) says (...) that I assume that life must be saved or prolonged at all costs. Christopher Dodsworth and colleagues (2008) say that I assume embryos have as much to lose as adults. I assume none of these things. The argument I put forward works just as well for more subdued claims about the moral status of the embryo. All that is required is to find the badness of embryo death to be at least roughly comparable to the badness of adult death, so that when a proponent of full moral status hears that 30 times more of our moral equals die of spontaneous abortion than die of cancer, their views would require urgent action if such action is possible. The comparison between the badness of adult death and of fetal or embryonic death is made routinely in the literature in support of restrictions upon abortion, in vitro fertilization (IVF) and stem cell research, and it appears to be a mainstream view worthy of serious attention.1 If a large proportion of those who claim that the embryo has full moral status are none-the-less quite sure that each embryo death is much less bad than an adult death, then they owe it to their readers to be more clear about this. Let us now consider the other points of each commentary in turn. (shrink)

Over the last few decades, there has been an increasing interest in global consequentialism. Where act-consequentialism assesses acts in terms of their consequences, global consequentialism goes much further, assessing acts, rules, motives — and everything else — in terms of the relevant consequences. Compared to act-consequentialism it offers a number of advantages: it is more expressive, it is a simpler theory, and it captures some of the benefits of ruleconsequentialism without the corresponding drawbacks. In this paper, I explore the four (...) different approaches to global consequentialism made by Parfit, Pettit and Smith, Kagan, and Feldman. I break these up into their constituent components, demonstrating the space of possible global consequentialist theories, and I present two new theories within this space. (shrink)

While it is well known that a Turing machine equipped with the ability to flip a fair coin cannot compute more than a standard Turing machine, we show that this is not true for a biased coin. Indeed, any oracle set X may be coded as a probability pX such that if a Turing machine is given a coin which lands heads with probability pX it can compute any function recursive in X with arbitrarily high probability. We also show how (...) the assumption of a non-recursive bias can be weakened by using a.. (shrink)

Value in the British National Health Service have shifted away from patient care towards financial control. However, in the quest for efficiency , huge amounts of NHS money have been wasted on computer system which failed. In this paper, I draw on a case study to explore some of the ethical issues which underlie this kind of waste of resources. Issues include the gap between public pronouncements and personal experience, the chaos of which lies behind the facade of rationality, and (...) the systematic silencing of people, usually women, who question the viability of computer systems which are created for private gain rather than public service.

It is common to allocate scarce health care resources by maximizing QALYs per dollar. This approach has been attacked by disability-rights advocates, policy-makers, and ethicists on the grounds that it unjustly discriminates against the disabled. The main complaint is that the QALY-maximizing approach implies a seemingly unsatisfactory conclusion: other things being equal, we should direct life-saving treatment to the healthy rather than the disabled. This argument pays insufficient attention to the downsides of the potential alternatives. We show that this sort (...) of discrimination is one of four unpalatable consequences that any approach to priority setting in health care must face. We argue that, given the alternatives, it is far from clear that we should revise the QALY-maximizing approach in response to this objection. (shrink)

A premise of this paper that despite an emphasis on professional distance the occurrence of self-disclosure is inevitable in the practice of youth work, yet there is little in-depth discussion in the literature, which recognises or reflects this. We utilise literature from counselling and psychotherapy which highlights the pervasive and unavoidable nature of self-disclosure within therapeutic relationships. In doing so we argue that not only is self-disclosure inevitable in youth work, but that decisions about whether or not particular disclosures are (...) right or wrong are difficult, arguing that they need to be reflected upon and explored in their particular context. We suggest some boundaries for self-disclosure, as well as offer a model within which to begin to distinguish aspects of self-disclosure. This it is hoped will help maintain both effective and professional relationships with young people, but maintain that this still requires the professional judgement of youth workers. In so doing self-disclosure is recognised as not only inevitable but as a useful aid to youth work practice. (shrink)

A major problem for interpersonal aggregation is how to compare utility across individuals; a major problem for decision-making under normative uncertainty is the formally analogous problem of how to compare choice-worthiness across theories. We introduce and study a class of methods, which we call statistical normalization methods, for making interpersonal comparisons of utility and intertheoretic comparisons of choice-worthiness. We argue against the statistical normalization methods that have been proposed in the literature. We argue, instead, in favor of normalization of variance: (...) we claim that this is the account that most plausibly gives all individuals or theories ‘equal say’. To this end, we provide two proofs that variance normalization has desirable properties that all other normalization methods lack, though we also show how different assumptions could lead one to axiomatize alternative statistical normalization methods.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

De thematische diversiteit van het boek weerspiegelt de biodiversiteit van Moyaerts eigen werk, die met enig geweld tot drie grote thema's of domeinen kan worden herleid: wijsgerige antropologie, psychopathologie en religie. Onderwerpen zijn: het symbolische, de liefde, uchronie, de echtheid van beelden, en poëzie; de afstemming bij jongvolwassenen met een meervoudige handicap, homoseksualiteit bij vrouwelijke adolescenten, (...) en Kant en Foucault; en ten slotte de hardnekkigheid van religie, christelijke ascese, de vele gezichten van Kierkegaard, Franciscus van Assisi, en de oorlogsdagboeken van Hans Keilson.
