This article provides a conceptual map of the debate on ideal and non‐ideal theory. It argues that this debate encompasses a number of different questions, which have not been kept sufficiently separate in the literature. In particular, the article distinguishes between the following three interpretations of the ‘ideal vs. non‐ideal theory’ contrast: (i) full compliance vs. partial compliance theory; (ii) utopian vs. realistic theory; (iii) end‐state vs. transitional theory. The article advances critical reflections on each of these sub‐debates, and highlights (...) areas for future research in the field. (shrink)

The aim of this article is twofold. First, it is argued that while the principle of ‘ought implies can’ is certainly plausible in some form, it is tempting to misconstrue it, and that this has happened in the way it has been taken up in some of the current literature. Second, Kant's understanding of the principle is considered. Here it is argued that these problematic conceptions put the principle to work in a way that Kant does not, so that there (...) is an important divergence here which can easily be overlooked.

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

abstract Even though much research has been devoted to studies of safety, the concept of safety is in itself under‐theorised, especially concerning its relation to epistemic uncertainty. In this paper we propose a conceptual analysis of safety. The paper explores the distinc‐tion between absolute and relative safety, as well as that between objective and subjective safety. Four potential dimensions of safety are discussed, viz. harm, probability, epistemic uncertainty, and control. The first three of these are used in the proposed definition (...) of safety, whereas it is argued that control should not be included in a reasonable definition of safety. It is shown that strictly speaking, an objective safety concept is not attainable. Instead, an intersubjective concept is proposed that brings us as close as possible to an objective concept.

This paper surveys the current philosophical discussion of the ethics of risk imposition, placing it in the context of relevant work in psychology, economics and social theory. The central philosophical problem starts from the observation that it is not practically possible to assign people individual rights not to be exposed to risk, as virtually all activity imposes some risk on others. This is the ‘problem of paralysis’. However, the obvious alternative theory that exposure to risk is justified when its total (...) benefits exceed its total costs faces the standard distributional challenges of consequentialism. Forms of contractualism have been proposed as a solution, but how exactly such theories can be formulated remains problematic, especially when confronted with the difficult cases of mass, novel, risk such as climate change.

Mainstream moral theories deal with situations in which the outcome of each possible action is well-determined and knowable. In order to make ethics relevant for problems of risk and uncertainty, moral theories have to be extended so that they cover actions whose outcomes are not determinable beforehand. One approach to this extension problem is to develop methods for appraising probabilistic combinations of outcomes. This approach is investigated and shown not to solve the problem. An alternative approach is then developed. Its (...) starting-point is that everyone has a prima facie moral right not to be exposed to risk. However, this right can be overridden if the risk-exposure is part of an equitable system for risk-taking that works to the advantage of the individual risk-exposed person. (shrink)

A shared presumption among practice-dependent theorists is that a principle of justice is dependent on the function or aim of the practice to which it is supposed to be applied. In recent contributions to this debate, the condition of epistemic uncertainty plays a significant role for motivating and justifying a practice-dependent view. This paper analyses the role of epistemic uncertainty in justifying a practice-dependent approach. We see two kinds of epistemic uncertainty allegedly playing this justificatory role. What we call ‘normative (...) epistemic uncertainty’ emerges from dealing with the problem of value uncertainty in justifying applied principles when our higher-level principles are open-textured, that is, when their content is too vague or unclear to generate determinate prescriptions. What we call ‘descriptive epistemic uncertainty’ emerges from dealing with uncertainty about empirical facts, such as the problem of moral assurance, that is, the problem that the requirements of justice cannot go beyond arrangements that we can know with reasonable confidence that we can jointly establish and maintain. In both cases, practice-dependent theorists conclude that the condition of epistemic uncertainty justifies a practice-dependent approach, which puts certain restrictions on theorizing regulative principles and has wide-ranging practical implications for the scope of justice. Our claim in this paper is that neither kind of epistemic uncertainty justifies a practice-dependent approach. (shrink)

An intensified discussion on the role of normative ideals has re-emerged in several debates in political philosophy. What is often referred to as “ideal theory,” represented by liberal egalitarians such as John Rawls, is under attack from those that stress that political philosophy at large should take much more seriously the nonideal circumstances consisting of relations of domination and power under which normative ideals, principles, and ideas are supposed to be applied. While the debate so far has mainly been preoccupied (...) with defending or rejecting ideal theory through a defense or rejection of a specific ideal theory, this paper instead focuses on a number of general philosophical concerns on which the critique relies. More specifically, it brings up for scrutiny, and ultimately rejects, three charges against ideal theory: the charge that ideal theory is not action-guiding, that ideal theory is impossible, and that ideal theory is distorting. By investigatingthese charges in tandem, the paper shows that the criticism against ideal theory is premised on assumptions about the relationships between thought and action and between concepts and the world for which there is little or no support.

Two essays on utilitarianism, written from opposite points of view, by J. J. C. Smart and Bernard Williams. In the first part of the book Professor Smart advocates a modern and sophisticated version of classical utilitarianism; he tries to formulate a consistent and persuasive elaboration of the doctrine that the rightness and wrongness of actions is determined solely by their consequences, and in particular their consequences for the sum total of human happiness. In Part II Bernard Williams offers a sustained (...) and vigorous critique of utilitarian assumptions, arguments and ideals. He finds inadequate the theory of action implied by utilitarianism, and he argues that utilitarianism fails to engage at a serious level with the real problems of moral and political philosophy, and fails to make sense of notions such as integrity, or even human happiness itself. This book should be of interest to welfare economists, political scientists and decision-theorists. (shrink)

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

If the global economy seems unfair, how should we understand what a fair global economy would be? What ideas of fairness, if any, apply, and what significance do they have for policy and law? Working within the social contract tradition, this book argues that fairness is best seen as a kind of equity in practice.

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)

Political philosophers have recently begun to take seriously methodological questions concerning what a theoretical examination of political ideals is suppose to accomplish and how effective theorising in ideal theory is in securing those aims. Andrew Mason and G.A. Cohen, for example, believe that the fundamental principles of justice are logically independent of issues of feasibility and questions about human nature. Their position contrasts sharply with political theorists like John Dunn and Joseph Carens who believe that normative theorising must be integrated (...) with an appreciation of the empirical realities of one’s society. Rather than bracket questions of feasibility and human nature, empirically-oriented political theorists believe that real, non- ideal considerations must be taken seriously when deriving normative theories of justice.1 And some justice-theorists, most notably John Rawls, attempt to.

Moral philosophers widely believe that it is a part of the MEANING of 'ought' statements that they imply 'can' statements. To this thesis I offer three challenges, and then I conclude on a broader methodological note. (1) Epistemological Modal Argument: for all we know, determinism is true; determinism contradicts “ought implies can”; therefore we don’t know that 'ought' implies 'can'. (2) Metaphysical Modal Argument: determinism is conceptually possible; determinism contradicts “ought implies can”; therefore “ought implies can” is not an analytic (...) truth. (3) Semantic Argument: “You ought to X” is equivalent to “Do X!”; but “Do X!” does not entail that you can X, according to leading analyses of the imperative. (4) My two modal arguments are epistemologically significant, for they illustrate a general method for refuting a whole class of argument. (shrink)
