Slippery slope arguments (SSAs) have often been viewed as inherently weak arguments, to be classified together with traditional fallacies of reasoning and argumentation such as circular arguments and arguments from ignorance. Over the last two decades several philosophers have taken a kinder view, often providing historical examples of the kind of gradual change on which slippery slope arguments rely. Against this background, Enoch (2001, Oxford Journal of Legal Studies 21(4), 629–647) presented a novel argument against SSA use that itself invokes (...) a slippery slope. Specifically, he argued that the very reasons that can make SSAs strong arguments mean that we should be poor at abiding by the distinction between good and bad SSAs, making SSAs inherently undesirable. We argue that Enoch’s meta-level SSA fails on both conceptual and empirical grounds. (shrink)

The article investigates the validity of two different versions of the slippery slope argument construed in relation to human gene therapy: the empirical and the conceptual argument. The empirical version holds that our accepting somatic cell therapy will eventually cause our accepting eugenic medical goals. The conceptual version holds that we are logically committed to accepting such goals once we have accepted somatic cell therapy. It is argued that neither the empirical nor the conceptual version of the argument can provide (...) a conclusive moral reason for banning somatic cell therapy. According to a third interpretation, referred to as the arbitrary result argument, the many apparent similarities between somatic cell therapy and eugenic-based human genetic engineering drive us to make principled choices concerning what differences and similarities between the two practices should be regarded as morally (ir)relevant. Decisions of this kind are likely to have unpredictable moral consequences. Thus formulated, the slippery slope argument has much plausibility. One objects to somatic cell therapy not so much because of what is at the bottom of the slope on which it lies, but because it is on a slope of which one does not know what is at the bottom. While the arbitrary result argument does not provide a conclusive reason for prohibiting human gene therapy, it reminds of a very important thing: when making bioethical decisions, we should be as specific and as consistent as possible about our basic moral and medical concepts.

Recently it has been argued that some instances of germ‐line gene therapy will change the identity of the person who receives the benefit of therapy, and that in these instances there is no good moral reason to conduct germ‐line gene therapy. Against this we argue that even if gene therapy should have an effect on the identity of the resulting person, this would not diminish the urgency of the therapy. Not only would impersonal moral reasons speak in favour of such (...) radical gene therapy, there would also be person‐affecting reasons to perform it. (shrink)

Addressing the slippery slope argument (SSA) in legal contexts from the perspective of pragma-dialectics, this paper elaborates the conditions under which an SSA-scheme instance is used reasonably (rather than fallaciously). We review SSA-instances in past legal decisions and analyze the basic legal SSA-scheme. By illustrating the institutional preconditions influencing the reasoning by which an SSA moves forward, we identify three sub-schemes (causal SSA, analogical SSA, and Sorites SSA). For each sub-scheme we propose critical questions, as well as four rules that (...) clarify when the SSA scheme is used reasonably. The institutional preconditions make the analogical SSA expectable in common law contexts; the Sorites SSA is expectable in civil law contexts; whereas the causal SSA is common to both contexts. This result should inform future work on the identification of typical argumentative patterns for the SSA in legal contexts. (shrink)

It is argued that justice in some cases provides a pro tanto reason genetically to enhance victims of the genetic lottery. Various arguments--both to the effect that justice provides no such reason and to the effect that while there may be such reasons, they are overridden by certain moral constraints--are considered and rejected. Finally, it is argued that justice provides stronger reasons to perform more traditional medical tasks (treatments), and that therefore genetic enhancements should not play an important role in (...) a public health care system.

This article applies tools from argumentation theory to slippery slope arguments used in current ethical debates on genetic engineering. Among the tools used are argumentation schemes, value-based argumentation, critical questions, and burden of proof. It is argued that so-called drivers such as social acceptance and rapid technological development are also important factors that need to be taken into account alongside the argumentation scheme. It is shown that the slippery slope argument is basically a reasonable form of argument, but is often (...) flawed when used in ethical debates because of failures to meet the requirements of its scheme.

We outline a number of ethical objections to genetic technologies aimed at enhancing human capacities and traits. We then argue that, despite the persuasiveness of some of these objections, they are insufficient to stop the development and use of genetic enhancement technologies. We contend that the inevitability of the technologies results from a particular guiding worldview of humans as masters of the human evolutionary future, and conclude that recognising this worldview points to new directions for ethical thinking about genetic enhancement (...) technologies.

We examine in detail three classic reasoning fallacies, that is, supposedly ``incorrect'' forms of argument. These are the so-called argumentam ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument. In each case, the argument type is shown to match structurally arguments which are widely accepted. This suggests that it is not the form of the arguments as such that is problematic but rather something about the content of those examples with which they are typically justified. This (...) leads to a Bayesian reanalysis of these classic argument forms and a reformulation of the conditions under which they do or do not constitute legitimate forms of argumentation. (shrink)

Contributors to the debate surrounding the ethics of germ line gene manipulation have by and large concentrated their efforts on discussions of the potential risks that are associated with the use of this technology. Many international advisory committees have ruled out the acceptability of germ line gene manipulation at least for the time being. The purpose of this work is to generate much needed discussion on the many other ethical issues concerning the implementation of not only germ line gene manipulation (...) but also other related biotechnologies. In this paper I systematically investigate and analyse the most salient issues put forward by proponents and opponents alike. I argue that if germ line manipulation proves to be a safe and effective procedure, then the principle of beneficence imposes on the medical profession a moral duty to pursue the technology.

The current article deals with the ethics and practice of physician-assisted suicide (PAS) and dying. The debate about PAS must take the important legal and ethical context of medical acts at the end of life into consideration, and cannot be examined independently from physicians’ duties with respect to care for the terminally ill and dying. The discussion in Germany about active euthanasia, limiting medical intervention at the end of life, patient autonomy, advanced directives, and PAS is not fundamentally different in (...) content and arguments from discussions led in other European countries and the United States. This must be emphasized, since it is occasionally claimed that in Germany a thorough discussion could not be held with the same openness as in other countries due to Germany’s recent history. Still, it is worthwhile to portray the debate, which has been held intensively both among experts and the German public, from the German perspective. In general, it can be stated that in Germany debates about questions of medical ethics and bioethics are taking place with relatively large participation of an interested public, as shown, for instance, by the intense recent discussions about the legalisation of advanced directives on June 18 2009, the generation and use of embryonic stem cells in research or the highly difficult challenges for the prioritizing and rationing of scarce resources within the German health care system. Hence, the current article provides some insights into central medical and legal documents and the controversial public debate on the regulation of end-of-life medical care. In conclusion, euthanasia and PAS as practices of direct medical killing or medically assisted killing of vulnerable persons as “due care” is to be strictly rejected. Instead, we propose a more holistically-oriented palliative concept of a compassionate and virtuous doctor-cared dying that is embedded in an ethics of care. (shrink)

The field of bioethics is increasingly coming into contact with empirical research findings. In this article, we ask what role empirical research can play in the process of ethical clarification and decision-making. Ethical reflection almost always proceeds in three steps: the description of the moral question,the assessment of the moral question and the evaluation of the decision-making. Empirical research can contribute to each step of this process. In the description of the moral object, first of all, empirical research has a (...) role to play in the description of morally relevant facts. It plays a role in answering the “reality-revealing questions” (what, why,how, who, where and when), in assessing the consequences and in proposing alternative courses of action. Secondly, empirical research plays a role in assessing the moral question. It must be acknowledged that research possesses “the normative power of the factual,” which can also become normative by suppressing other norms. However, inductive normativity should always be balanced out by a deductive form of normativity. Thirdly, empirical research also has a role to play in evaluating the decision-making process. It can rule out certain moral choices by pointing out the occurrence of certain unexpected consequences or effects. It can also be useful, however, as a sociology of bioethics in which the discipline of bioethics itself becomes an object of research. (shrink)

This case is another in a series intended to highlight the new questions emerging from advances in mapping the human genome and the application of genetic findings to clinical practice. The National Human Genome Research Institute, a component of the National Institutes of Health, by law is directed to designate a portion of its annual budget to furthering understanding of the ethical, legal, and social questions emerging from research on the human genome. As part of the effort, the Institute supports (...) research by scientists and scholars around the nation with the aim of clarifying and resolving the tough ethical and research choices facing this endeavor. But recently it has launched an intramural program, which is expected to take a catalytic role in grappling with the array of issues the researchers face in carrying out investigations in human genetics.

The case in favor of gene therapy is quite simple. Gene therapy is likely to improve the health and well-being of some people that are among the worst off in society, namely patients with painful and life-threatening diseases. However, two types of objection have been raised.

This article examines the relation between policies concerning Corporate Social Responsibility (CSR) and philosophical moral theories. The objective is to determine which moral theories form the basis for CSR policies. Are they based on ethical egoism, libertarianism, utilitarianism or some kind of common-sense morality? In order to address this issue, I conducted an empirical investigation examining the relation between moral theories and CSR policies, in companies engaged in CSR. Based on the empirical data I collected, I start by suggesting some (...) normative arguments used by the respondents. Secondly, I suggest that these moral arguments implicitly rely on some specific moral principles, which I characterise. Thirdly, on the basis of these moral principles, I suggest the moral theories upon which the CSR policies are built. Previous empirical studies examining the relation between philosophical moral theories and the ethical content of business activities have mainly concentrated on the ethical decision-making of managers. Some of the most prominent investigations in that regard propose that managers mainly act in accordance with utilitarian moral theory (Fritzsche, D. J. and H. Becker: 1984 , Academy of Management Journal 27 (1), 166–175; Premeaux, S. and W. Mony: 1993 , Journal of Business Ethics 12 , 349–357; Premeaux, S.: 2004 , Journal of Business Ethics 52 , 269–278). I conclude that CSR policies are not based on utilitarian thinking, but instead, on some kind of common-sense morality. The ethical foundation of companies engaged in CSR, thus, does not mirror the ethical foundation of managers. (shrink)
