Communication is complicated, and so is the ethics of communication. We communicate about innumerable topics, to varied audiences, using a gamut of technologies. The ethics of communication, therefore, has to address a wide range of technical, ethical and epistemic requirements. In this book, Onora O'Neill shows how digital technologies have made communication more demanding: they can support communication with huge numbers of distant and dispersed recipients; they can amplify or suppress selected content; and they can target or ignore selected audiences. Often this is done anonymously, making it harder for readers and listeners, viewers and browsers, to assess which claims are true or false, reliable or misleading, flaky or fake. So how can we empower users to assess and evaluate digital communication, so that they can tell which standards it meets and which it flouts? That is the challenge which this book explores.

Who ought to do what, and for whom, if global justice is to progress? In this collection of essays on justice beyond borders, Onora O'Neill criticises theoretical approaches that concentrate on rights, yet ignore both the obligations that must be met to realise those rights, and the capacities needed by those who shoulder these obligations. She notes that states are profoundly anti-cosmopolitan institutions, and that even those committed to justice and universal rights often lack the competence and the will to secure them, let alone to secure them beyond their borders. She argues for a wider conception of global justice, in which obligations may be held either by states or by competent non-state actors, and in which borders themselves must meet standards of justice. This rich and wide-ranging collection will appeal to a broad array of academic researchers and advanced students of political philosophy, political theory, international relations and philosophy of law.

'Two things', wrote Kant, 'fill the mind with ever new and increasing admiration and awe: the starry heavens above and the moral law within'. Many would argue that since Kant's day, the study of the starry heavens has advanced while ethics has stagnated, and in particular that Kant's ethics offers an empty formalism that tells us nothing about how we should live. In Acting on Principle Onora O'Neill shows that Kantian ethics has practical as well as philosophical importance. First published in 1975, the book is regarded as a classic account and defence of the Kantian ethical position. It addresses Kant's account of reasoning about action, in particular his controversial claim that the Categorical Imperative guides action and is basic to ethics and justice. This second edition offers a substantial new introduction and updated bibliography, and will be valuable for a wide readership in Kant studies and those studying ethics.

Can trust be restored by making people and institutions more accountable? Or do complex systems of accountability and control damage trust? Onora O'Neill challenges current approaches, investigates sources of deception in our society and re-examines questions of press freedom. This year's Reith Lectures present a philosopher's view of trust and deception and ask whether and how trust can be restored in modern democracy.

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 with 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 medicine, science and technology. The study appeals to a wide range of readers in ethics, bioethics and related disciplines.

In this collection of essays, Onora O'Neill argues for an account of justice that is fundamentally cosmopolitan rather than civic, yet takes serious account of institutions and boundaries, and of human diversity and vulnerability. She explores the question of whether the claims and scope of justice are limited by culturally or politically specific concepts and views, and examines the demands and scope of just institutions and the possibility of a world with porous boundaries and dispersed power. Bounds of Justice will appeal to readers in philosophy, politics and international relations.

This collection of essays brings together the central lines of thought in Onora O'Neill's work on Kant's philosophy, developed over many years. Challenging the claim that Kant's attempt to provide a critique of reason fails because it collapses into a dogmatic argument from authority, O'Neill shows why Kant held that we must construct, rather than assume, the authority of reason, and how this can be done by ensuring that anything we offer as reasons can be followed by others, including others with whom we disagree. She argues that this constructivist view of reasoning is the clue to Kant's claims about knowledge, ethics and politics, as well as to his distinctive accounts of autonomy, the social contract, cosmopolitan justice and scriptural interpretation. Her essays are a distinctive and illuminating commentary on Kant's fundamental philosophical strategy and its implications, and will be a vital resource for scholars of Kant, ethics and philosophy of law.

Towards Justice and Virtue challenges the rivalry between those who advocate only abstract, universal principles of justice and those who commend only the particularities of virtuous lives. Onora O'Neill traces this impasse to defects in underlying conceptions of reasoning about action. She proposes and vindicates an alternative, more modest, account of ethical reasoning, a reasoned way of answering the question "who counts?," and constructs a linked account of the principles that are basic for moving toward just institutions and virtuous lives.

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 attempt 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, automony and action. She then moves on to the more familiar terrain of interpretation of the Categorical Imperative, while in the last section she emphasises differences between Kant's ethics and recent 'Kantian' ethics, including the work of John Rawls and other contemporary liberal political philosophers. This reassessment will add significantly to the understanding of Kantian practical philosophy.

Knowledge aims to fit the world, and action to change it. In this collection of essays, Onora O'Neill explores the relationship between these concepts and shows that principles are not enough for ethical thought or action: we also need to understand how practical judgement identifies ways of enacting them and of changing the way things are. Both ethical and technical judgement are supported, she contends, by bringing to bear multiple considerations, ranging from ethical principles to real-world constraints, and while we will never find practical algorithms - let alone ethical algorithms - that resolve moral and political issues, good practical judgement can bring abstract principles to bear in situations that call for action. Her essays thus challenge claims that all inquiry must use either the empirical methods of scientific inquiry or the interpretive methods of the humanities. They will appeal to a range of readers in moral and political philosophy.

Informed consent is a central topic in contemporary biomedical ethics. Yet attempts to set defensible and feasible standards for consenting have led to persistent difficulties. In Rethinking Informed Consent in Bioethics, first published in 2007, Neil Manson and Onora O'Neill set debates about informed consent in medicine and research in a fresh light. They show why informed consent cannot be fully specific or fully explicit, and why more specific consent is not always ethically better. They argue that consent needs distinctive communicative transactions, by which other obligations, prohibitions, and rights can be waived or set aside in controlled and specific ways. Their book offers a coherent, wide-ranging and practical account of the role of consent in biomedicine which will be valuable to readers working in a range of areas in bioethics, medicine and law.

Ethical concepts are, or purport to be, normative. They make claims on us: they command, oblige, recommend, or guide. But where does their authority over us come from? Christine Korsgaard identifies and examines four accounts of the source of normativity that have been advocated by modern moral philosophers--voluntarism, realism, reflective endorsement, and the appeal to autonomy--and shows how Kant's autonomy-based account emerges as a synthesis of the other three. Her discussion is followed by commentary from G.A. Cohen, Raymond Geuss, Thomas Nagel, and Bernard Williams, and a reply by Korsgaard.

Judgment, Imagination, and Politics brings together for the first time leading essays on the nature of judgment. Drawing from themes in Kant's Critique of Judgment and Hannah Arendt's discussion of judgment from Lectures on Kant's Political Philosophy, these essays deal with: the role of imagination in judgment; judgment as a distinct human faculty; the nature of judgment in law and politics; and the many puzzles that arise from the 'enlarged mentality, ' the capacity to consider the perspectives of others that aren't in Kant treated as essential to judgment
