The precautionary principle has been widely discussed in the academic, legal, and policy arenas. This paper argues, however, that there is no single precautionary principle and we should stop referring to ?the? precautionary principle. Instead, we should talk about ?precaution? and ?precautionary approaches? more generally and identify and defend distinct precautionary principles of limited scope. Drawing on the vast literature on ?the? precautionary principle, this paper further argues that the challenges of decision making under conditions of uncertainty necessitate taking a (...) precautionary approach to decision making that will enable us to understand what particular precautionary principles require of us on a case-by-case basis.

The article investigates the resources of contractualist moral theory to make sense of the ethics of risk imposition. In some ways, contractualism seems well placed to explain how it can be reasonable to accept exposure to risk of harms whose direct imposition would not be acceptable. However, there are difficulties getting clear about what directness comes to here, especially given the difficulty of adequately motivating traditional views that assign ethical significance to what the agent intends as opposed to merely foreseeing. (...) The article considers two principles which might help the contractualist: the Redistribution Principle, which, while attractive, is perhaps somewhat too restrictive, and the Aim Consistency Principle, which grants ethical significance to the aims with which our actions are in principle consistent whatever our actual intentions may be. The article also considers the relative significance of ex ante and ex post perspectives from which to evaluate actions and principles. Key Words: contractualism • Doctrine of Double Effect • ethics • intention • justice • risk • T.M. Scanlon • utilitarianism. (shrink)

How should automated vehicles react in emergency circumstances? Most research projects and scientific literature deal with this question from a moral perspective. In particular, it is customary to treat emergencies involving AVs as instances of moral dilemmas and to use the trolley problem as a framework to address such alleged dilemmas. Some critics have pointed out some shortcomings of this strategy and have urged to focus on mundane traffic situations instead of trolley cases involving AVs. Besides, these authors rightly point (...) out the political nature of the most interesting debates involving AVs. However, in our view, they do not offer an adequate account of the distinction between ethics and politics and still see their proposals as contributions to the ethics of AVs. We argue that many of the interesting questions about how AVs should behave, both in emergency and other situations, are of political, and not moral, nature. This view is based on a conception of politics and political normativity that we have developed elsewhere and that we call “political minimalism.” Additionally, we show that this proposed perspective has significant consequences for the design, management, and regulation of transport systems.

With very advanced technology, a very large population of people living happy lives could be sustained in the accessible region of the universe. For every year that development of such technologies and colonization of the universe is delayed, there is therefore a corresponding opportunity cost: a potential good, lives worth living, is not being realized. Given some plausible assumptions, this cost is extremely large. However, the lesson for standard utilitarians is not that we ought to maximize the pace of technological (...) development, but rather that we ought to maximize its safety, i.e. the probability that colonization will eventually occur. This goal has such high utility that standard utilitarians ought to focus all their efforts on it. Utilitarians of a ‘person-affecting’ stripe should accept a modified version of this conclusion. Some mixed ethical views, which combine utilitarian considerations with other criteria, will also be committed to a similar bottom line. (shrink)

What is political philosophy’s relation to moral philosophy? Does it simply form part of moral philosophy, focusing on the proper application of certain moral truths to political reality? Or must it instead form a more autonomous discipline, drawing its bearings from the specifically political problem of determining the bounds of legitimate coercion? In this essay I work out an answer to these questions by examining both some of the classical views on the nature of political philosophy and, more particularly, some (...) recently published writings by Bernard Williams and G.A. Cohen. (shrink)

This paper begins a working through of Blair’s (2001) theoretical agenda concerning argumentation schemes and their attendant critical questions, in which we propose a number of solutions to some outstanding theoretical issues. We consider the classification of schemes, their ultimate nature, their role in argument reconstruction, their foundation as normative categories of argument, and the evaluative role of critical questions.We demonstrate the role of schemes in argument reconstruction, and defend a normative account of their nature against specific criticisms due to (...) Pinto (2001). Concerning critical questions, we propose an account on which they are founded in the R.S.A. cogency standard, and develop an account of the relationship between critical questions and burden of proof. Our ultimate aim is to initiate a reconciliation between dialectical and informal logic approaches to the schemes. (shrink)

This paper argues that a precautionary approach to scientific progress of the sort advocated by Walter Glannon with respect to life-extending therapies involves both incoherence and irresolvable paradox. This paper demonstrates the incoherence of the precautionary approach in many circumstances and argues that with respect to life-extending therapies we have at present no persuasive reasons for a moratorium on such research.

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)

The precautionary principle has its origins in debates about environmental policy, but is increasingly invoked in bioethical contexts. John Harris and Søren Holm argue that the principle should be rejected as incoherent, irrational, and representing a fundamental threat to scientific advance and technological progress. This article argues that while there are problems with standard formulations of the principle, Harris and Holm's rejection of all its forms is mistaken. In particular, they focus on strong versions of the principle and fail to (...) recognize that weaker forms, which may escape their criticisms, are both possible and advocated in the literature.

“[T]he Precautionary Principle still has neither a commonly accepted definition nor a set of criteria to guide its implementation. “There is”, Freestone … cogently observes, “a certain paradox in the widespread and rapid adoption of the Precautionary Principle”: While it is applauded as a “good thing”, no one is quite sure about what it really means or how it might be..

The precautionary principle states, roughly, that it is better to take precautionary measures now than to deal with serious harms to the environment or human health later on. This paper builds on the work of Neil A. Manson in order to show that the precautionary principle, in all of its forms, is fraught with vagueness and ambiguity. We examine the version of the precautionary principle that was formulated at the Wingspread Conference sponsored by the Science and Environmental Health Network in (...) 1998. That version fails to indicate who must bear the cost of precaution; what constitutes a threat of harm; how much precaution is too much; and what should be done when environmental concerns and concern for human health pull in different directions. Whether this vagueness is a strength or weakness of the principle depends on what purpose(s) the precautionary principle is supposed to serve. (shrink)

Over the past three decades, the Precautionary Principle has become popular in discussions of public policy, especially in relation to health and environmental policy. Though there are a number of different versions of the principle, the genesis of the idea is that it is better to be safe than sorry. In terms of public policy, proponents of the PP argue that being safe means that, if there is a possibility of harm from a new activity or novel technology, even if (...) the scientific evidence concerning the harm is absent or uncertain, precautionary actions should be taken. In one version or another, the PP has been incorporated into a number of laws and treaties. Yet arguments for the PP are unconvincing, the PP itself is vague and when enacted in law, results in arbitrary regulations that pose a threat to human welfare. As a result, the PP should be rejected as a basis for public policy. (shrink)

In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criticize it in light of its similarities to the principle at work in Pascal’s Wager. I conclude with some suggestions for (...) advocates of the precautionary principle who wish their formulation to avoid the pitfalls confronting the catastrophe principle. (shrink)

The precautionary principle (“the Principle”) has been widely embraced as the new paradigm for contending with biological and environmental risk in the context of emerging technologies. Increasingly, it is being incorporated into domestic, supranational, and international legal regimes as part of a general overhaul of health and environmental regulation.1 Codifications of the Principle typically are vague, with their content intentionally left for scholars to debate, decision makers to interpret, and the courts to flesh out through case law. Generally speaking, the (...) Principle holds that scientific uncertainty will not be a bar to preventive regulatory action, and that decision makers should err on the side of .. (shrink)

In the past, it was possible to approach transhumanism as primarily involving philosophical discussion and technological speculation. While transhumanist goals such as radical life extension, uploading, and cognitive, sensory, and physical enhancement were speculative they were also considered scientifically feasible, even if the technologies to achieve those goals appeared remote.

What is the relationship between morals and politics? What is the relationship between moral philosophy and political philosophy? Defenders of political moralism postulate moral aims or constraints for politics, and hence they see political philosophy as a chapter of moral philosophy. Contrastingly, advocates of political realism describe politics as an independent endeavor aiming at providing order and security, and conceive of political philosophy as an autonomous discipline. This article claims that political moralism and political realism share the mistake of assuming (...) that politics has substantial, permanent goals or constraints. After criticizing political substantialism, the article explains the main ingredients of its alternative, political minimalism: the idea that politics, understood as collective instrumental rationality, aims at providing adequate means for the accomplishment of people's goals, whatever these are; and the conception of the relationship between morality and politics as one of “reciprocal containment.” Finally, it addresses some foreseeable criticisms of political minimalism.

Innovation in basic science is often a cause for won­der and excitement. Those associated with a new development are quick to point out the anticipated benefits: a cure for cancer or dementia, an end to unsafe water or hunger. These advocates are slower to draw at­tention to the possible costs, which may become known only much later. It is always hard to have an accurate overview, as it is almost impossible to predict the total effects of the widespread adoption of (...) any new technology and, especially, its longer‐term or cumulative effects, as as­bestos and CFCs demonstrate. For this reason, some policy‐makers or members of the public hope that we can apply “the precautionary principle” to innovation. Unfortunately, if one is looking for a principle that can guide action, then, strictly speaking, there is no pre­cautionary principle. One might better speak of a “pre­cautionary approach,” although even this needs to be unpacked. (shrink)

Rule consequentialism (RC) holds that the rightness and wrongness of actions is determined by an ideal moral code, i.e., the set of rules whose internalization would have the best consequences. But just how many moral codes are there supposed to be? Absolute RC holds that there is a single morally ideal code for everyone, while Relative RC holds that there are different codes for different groups or individuals. I argue that Relative RC better meets the test of reflective equilibrium than (...) Absolute RC. In particular, I contend that Relative RC is superior because it accommodates our convictions about costless benefits. Some have charged that Relative RC threatens our convictions about the generality of moral codes and that it leads inevitably to what Brad Hooker calls “runaway relativism.” I argue that Relative RC has principled reasons for stopping this imagined slide down the slippery slope.

There are thousands of substances manufactured in the United States to which the public is routinely exposed and for which toxicity data are limited or absent. Some insist that uncertainty about the severity of potential harm justifies implementing precautionary regulations, while others claim that uncertainty justifies the absence of regulations until sufficient evidence confirms a strong probability of severe harm. In this book, Levente Szentkirályi overcomes this impasse in his defense of precautionary environmental risk regulation by shifting the focus from (...) how to manage uncertainty to what it is we owe each other morally. He argues that actions that create uncertain threats wrongfully gamble with the welfare of those who are exposed and neglect the reciprocity that our equal moral standing demands. If we take the moral equality and rights of others seriously, we have a duty to exercise due care to strive to prevent putting them in possible harm's way. The Ethics of Precaution will be of great interest to researchers, educators, advanced students, and practitioners working in the fields of environmental political theory, ethics of risk, and environmental policy.

Precaution is usually associated with the intuition that it is better to be safe than sorry, and/or that it is sometimes necessary to act in advance of scientific certainty to prevent harmful outcomes. At this point, we cannot entirely prevent climate change, but we can affect how harmful such change is. Adaptation may therefore be understood as a precautionary measure against the damage due to climate change. 'The' precautionary principle alone is too vague to shape adaptation policy, but a limited (...) catastrophic precautionary principle may productively guide adaptation policy makers. I argue in this paper that an explicit commitment to a precautionary approach based on the catastrophic precautionary principle could and should be made to strengthen the adaptation policies introduced at the United Nations Framework Convention on Climate Change (UNFCCC).
