The question of how to distinguish between science and non-science, the so-called ‘demarcation problem’, is one of the most high-profile, perennial, and intractable issues in the philosophy of science. It is not merely a philosophical issue, however, since it has a significant bearing on practical policy questions and practical decisions. This essay develops a pragmatic approach to the demarcation problem: it argues that while there are some core principles that we can use in distinguishing between science and non-science, particular judgments (...) and decisions about something's scientific status depend, in part, on practical goals and concerns.

In this introduction, I summarize the main themes of my book, particularly those that my critics have focused on in their papers that follow. I also argue that I could not have reached the conclusions that I have if I hadn’t employed a peacemaking rather than a warmaking way of doing philosophy. I provide a characterization of a peacemaking way of doing philosophy and show how the conclusions of my book depend on doing philosophy in that way.

There seem to be two clearly-defined camps in the debate over the problem of moral expertise. On the one hand are the “Professionals”, who reject the possibility entirely, usually because of the intractable diversity of ethical beliefs. On the other hand are the “Ethicists”, who criticise the Professionals for merely stipulating science as the most appropriate paradigm for discussions of expertise. While the subject matter and methodology of good ethical thinking is certainly different from that of good clinical thinking, they (...) argue, this is no reason for rejecting the possibility of a distinctive kind of expertise in ethics, usually based on the idea of good justification. I want to argue that both are incorrect, partly because of the reasons given by one group against the other, but more importantly because both neglect what is most distinctive about ethics: that it is personal in a very specific way, without collapsing into relativism.

Ethical naturalism holds that ethical facts about such matters as good and bad, right and wrong, are part of a purely natural world — the world studied by the sciences. It is supported by the apparent reasonableness of many moral explanations. It has been thought to face an epistemological challenge because of the existence of an “is-ought gap”; it also faces metaphysical objections from philosophers who hold that ethical facts would have to be supernatural or “nonnatural,” sometimes on the grounds (...) that ethical thought has a practical role that no thought about purely natural facts could have. Its defenders have argued resourcefully against these challenges. (shrink)

Using the bench trial of Colorado’s Amendment 2 as an example, this article focuses on the more general question of expert testimony in moral philosophy. It argues that there is indeed expertise in moral philosophy but argues against admitting such expert testimony in cases dealing with what John Rawls terms “constitutional essentials” and ‘matters of basic justice.” Developing the idea of public reason inherent in the Rawlsian concept of political liberalism, the article argues that philosophers can and should speak out (...) on public issues, if they do so with due respect for certain restrictions, but that they should not serve as expert witnesses on core constitutional questions, since doing so suggests that they claim a type of authority that would require fellow citizens to defer to their views. Such claims to authority in basic ethical matters threaten the mutual respect for divergent comprehensive doctrines that lies at the core of political liberalism. Philosophers have a duty to serve the public good, and they perform this service in fruitful ways. But they should refuse a public role that appears incompatible with equal respect for the committed ethical searching of their fellow citizens. (shrink)

ABSTRACT Many people argue that disagreements and inconsistencies between Research Ethics Committees are morally problematic and there has been much effort to ‘harmonise’ their judgements. Some inconsistencies are bad because they are due to irrationality, or carelessness, or the operation of conflicting interests, and so should be reduced or removed. Other inconsistencies, we argue, are not bad and should be left or even encouraged. In this paper we examine three arguments to reject the view that we should strive for complete (...) consistency between committees. The first argument is that differences in judgement are not necessarily incompatible with ideas of justice for patients who are potential participants of research reviewed by different committees. We call this ‘the justice argument.’ The second argument is that such committees do not have access to a single moral truth, to which their judgement is supposed to correspond. We call this the ‘moral pluralism argument.’ The third argument is that the process of ethics committee review is also morally relevant and not solely the outcome. We call this the ‘due process argument.’ While we fall short of establishing exactly how much variation and on what substantive issues would be ethically permissible, we show that it is largely inevitable and that a certain amount of variation could be seen as a desirable part of the institution of medical research.

: The increasing reliance upon, and perhaps the growing public and professional skepticism about, the special expertise of bioethicists suggests the need to consider the limits of moral expertise. For all the talk about method in bioethics, we, bioethicists, are still rather far off the mark in understanding what we are doing, even when we may be going about what we are doing fairly well. Quite often, what is most fundamentally at stake, but equally often insufficiently acknowledged, are inherently political, (...) essentially contested visions of the most compelling and attractive forms of life for individuals and social organization. The current situation in bioethics parallels similar debates in eighteenth-century jurisprudence, especially Jeremy Bentham's withering critique of the prevalent forms of judicial argument and his own, equally unsuccessful, attempt to develop a decision-making procedure in ethics that would operate on a plane above politics. The risk, both then and now, is that we will fail to appreciate the wide range of reasonable disagreement that will remain past the point of extended reflection and discussion. (shrink)

The chapter discusses the various ways in which ethical theory and moral practice relate to one another. Various proposals are discussed and evaluated, such as that the relation is a deductive one, that the relation is one of norm-specification, or that the theory provides multiple moral principles that must be balanced against one another. The author makes some suggestions on how the relation between theory and practice should be understood.
