Abstract: Vague predicates, those that exhibit borderline cases, pose a persistent problem for philosophers and logicians. Although they are ubiquitous in natural language, when used in a logical context, vague predicates lead to contradiction. This paper will address a question that is intimately related to this problem. Given their inherent imprecision, why do vague predicates arise in the first place? I discuss a variation of the signaling game where the state space is treated as contiguous, i.e., endowed with a metric that captures a similarity relation over states. This added structure is manifested in payoffs that reward approximate coordination between sender and receiver as well as perfect coordination. I evolve these games using a variation of Herrnstein reinforcement learning that better reflects the generalizing learning strategies real-world actors use in situations where states of the world are similar. In these simulations, signaling can develop very quickly, and the signals are vague in much the way ordinary language predicates are vague - they each exclusively apply to certain items, but for some transition period both signals apply to varying degrees. Moreover, I show that under certain parameter values, in particular when state spaces are large and time is limited, learning generalization of this sort yields strategies with higher payoffs than standard Herrnstein reinforcement learning. These models may then help explain why the phenomenon of vagueness arises in natural language: the learning strategies that allow actors to quickly and effectively develop signaling conventions in contiguous state spaces make it unavoidable

Introduction: Are Constructivism and Contractualism different, and if so how? Seemingly they are not wholly different, and certainly not incompatible, since some writers have described themselves as both. As a first shot one might suggest that contractualists ground ethical or political justification in agreement of some sort, whereas constructivists ground them in some conception of reason. This will not provide any neat separation of the two approaches to justification, since agreement may provide a basis for reasons, and reasoning a way of achieving agreement. In opening up these questions a bit further I shall consider some of the moves John Rawls and Tim Scanlon make in talking about their own methods of ethics, and in particular, some of the connections they draw between their methods and the scope of their accounts of ethical reasoning.

Abstract: Inevitably a policy-oriented report on issues as complex and as rapidly changing as the medical and scientific uses of human tissue can achieve neither philosophical purity nor regulatory completeness. The council's strategy has been to begin with robust ethical principles, for which sound philosophical arguments can be given, which will (it is hoped) command widespread support. The council went on to argue for guidelines of sufficient, but not vapid, generality which could be of practical use to the various medical intermediaries, professional and regulatory bodies and research ethics committees which will carry out the tasks of detailed regulation and of making decisions that affect uses of human tissue. The council's hope is that the recommendations of the report can be absorbed into regulatory and professional practice, and where needed into government policy. If they can, the increasing diversity of uses of human tissues need lead neither to overt nor to covert 'commercialisation of the human body', but will also not put unnecessary restrictions on advances in research and medical practice.

Abstract: Conceptions of individual autonomy and of rational autonomy have played large parts in twentieth century moral philosophy, yet it is hard to see how either could be basic to morality. Kant's conception of autonomy is radically different. He predicated autonomy neither of individual selves nor of processes of choosing, but of principles of action. Principles of action are Kantianly autonomous only if they are law-like in form and could be universal in scope; they are heteronomous if, although law-like in form, they cannot have universal scope. Puzzles about claims linking morality, reason and autonomy are greatly reduced by recognising the distinctiveness of Kantian autonomy

Publisher's Note: Onora O'Neill suggests that the conceptions of individual autonomy (so widely relied on in bioethics) are philosophically and ethically inadequate; they undermine rather than support relationships based on trust. Her arguments are illustrated by issues raised by such practices as the use of genetic information by the police, research using human tissues, new reproductive technologies, and media practices for reporting on science, medicine, and technology. The study appeals to a wide range of readers in ethics, bioethics, and related disciplines.

Abstract: LIBERALS OFTEN THINK diversity of belief and its expression should be tolerated in order to respect either individuals or reason and truth themselves. Because they are agnostic about the good for man, they hold that liberty for each to pursue his or her conception of the good in "self-regarding" matters is required, and that practices of toleration are important aspects of this liberty. They also often advocate practices of toleration as means by which reasoned and true beliefs can come to prevail over false beliefs. Each line of thought justifies practices of toleration as means to something which is seen both as logically independent and as of more fundamental value. These familiar lines of thought are not the only possible liberal vindication of toleration. In Kant's writings toleration is not a derivative value, to be established only when the value of true and reasoned belief and of liberty in self-regarding matters has been established. His arguments for toleration of what he terms "the public use of reason" presuppose neither antecedently given standards of rationality nor that any class of self-regarding individual actions is of special importance. For Kant the importance of (some sorts of) toleration is connected with the very grounding of reason, and so in particular with the grounding of practical reason. His arguments suggest that liberal political thinking can vindicate practices of toleration without commitment either to a strong form of individualism or to the view that we can distinguish "self-regarding" acts, and without claiming that reasoning either has a "transcendent" vindication or is groundless. The themes of toleration and of the grounding of reason are brought together in many Kantian texts. The most important is the Critique of Pure Reason, in particular the section of the Doctrine of Method called "The Discipline of Pure Reason in Respect of its Polemical Employment." I The same connection is stressed in many other places, including scattered passages in the Second and Third Critiques, in the Logic, and in Religion within the Limits of Reason Alone. A number of shorter essays, including "What Is Enlightenment?" (1784), "What Is Orientation in Thinking?" (1786), "Idea for a Universal History with a Cosmopolitan Purpose" (1784), "The Conflict of the Faculties" (1798), "On the Common Saying 'This may be True in Theory, but it does not Apply in Practice' " (1795), and "Perpetual Peace" (1795),2 appear at first to have much to say about toleration, including the political aspects of toleration, and little about the grounding of reason. Yet here too the themes are often interwoven. The close connections between the short political essays and the central critical writings suggest not only that the essays are part of Kant's systematic philosophy, and not marginal or occasional pieces, but also perhaps that the entire critical enterprise has a certain political character. If this is the case, it is no accident that the guiding metaphors of The Critique of Pure Reason are political metaphors. If the discussion of reason itself is to proceed in terms of conflicts whose battlefields and strife are scenes of defeat and victory that will give way to a lasting peace only when we have established through legislation such courts, tribunals, and judges as can weigh the issue and give verdict, then it is perhaps not surprising that Kant links his discussions of politics very closely to larger issues about the powers and limits of human reason. However, this is a large and for present purposes somewhat tangential issue.3 The more immediate concern is to see how Kantian arguments link toleration to the very grounding of reason.

Abstract: Many accounts of informed consent in medical ethics claim that it is valuable because it supports individual autonomy. Unfortunately there are many distinct conceptions of individual autonomy, and their ethical importance varies. A better reason for taking informed consent seriously is that it provides assurance that patients and others are neither deceived nor coerced. Present debates about the relative importance of generic and specific consent (particularly in the use of human tissues for research and in secondary studies) do not address this issue squarely. Consent is a propositional attitude, so intransitive: complete, wholly specific consent is an illusion. Since the point of consent procedures is to limit deception and coercion, they should be designed to give patients and others control over the amount of information they receive and opportunity to rescind consent already given.

Publisher's Note: We say we can no longer trust our public services, institutions or the people who run them. The professionals we have to rely on - politicians, doctors, scientists, businessmen and many others - are treated with suspicion. Their word is doubted, their motives questioned. Whether real or perceived, this crisis of trust has a debilitating impact on society and democracy. Can trust be restored by making people and institutions more accountable? Or do complex systems of accountability and control themselves damage trust? Onora O'Neill challenges current approaches, investigates sources of deception in our society and re-examines questions of press freedom. 2002's Reith Lectures present a philosopher's view of trust and deception, and ask whether and how trust can be restored in a modern democracy.

Publisher's Note: Two centuries after they were published, Kant's ethical writings are as much admired and imitated as they have ever been, yet serious and long-standing accusations of internal incoherence remain unresolved. Onora O'Neill traces the alleged incoherences to attempts to assimilate Kant's ethical writings to modern conceptions of rationality, action and rights. When the temptation to assimilate is resisted, a strikingly different and more cohesive account of reason and morality emerges. Kant offers a "constructivist" vindication of reason and a moral vision in which obligations are prior to rights and in which justice and virtue are linked. O'Neill begins by reconsidering Kant's conceptions of philosophical method, reason, freedom, autonomy and action. She then moves on to the more familiar terrain of interpretation of the Categorical Imperative, while in the last section she emphasizes differences between Kant's ethics and recent "Kantian" ethics, including the work of John Rawls and other contemporary liberal political philosophers

Abstract: In Easeful Death: Is There a Case for Assisted Dying? Mary and Elisabeth Macdonald set out with exemplary clarity reasons for prohibiting or permitting physicians to 'help' patients to die. Their arguments are cogent, illuminating, and in many ways convincing. Yet I find myself disagreeing with their conclusion that assisted dying should be made lawful, and will set out why.
