This paper is the introduction to the volume. It gives an argumentative view of the philosophical landscape concerning incommensurability and incomparability. It argues that incomparability, not incommensurability, is the important phenomenon on which philosophers should be focusing and that the arguments for the existence of incomparability are so far not compelling.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

To hold an environmental ethic is to hold that non-human beings and states of affairs in the natural world have intrinsic value. This seemingly straightforward claim has been the focus of much recent philosophical discussion of environmental issues. Its clarity is, however, illusory. The term ‘intrinsic value’ has a variety of senses and many arguments on environmental ethics suffer from a conflation of these different senses: specimen hunters for the fallacy of equivocation will find rich pickings in the area. This (...) paper is largely the work of the underlabourer. I distinguish different senses of the concept of intrinsic value, and, relatedly, of the claim that non-human beings in the natural world have intrinsic value; I exhibit the logical relations between these claims and examine the distinct motivations for holding them. The paper is not however merely an exercise in conceptual underlabouring. It also defends one substantive thesis: that while it is the case that natural entities have intrinsic value in the strongest sense of the term, i.e., in the sense of value that exists independently of human valuations, such value does not as such entail any obligations on the part of human beings. The defender of nature’s intrinsic value still needs to show that such value contributes to the well-being of human agents. (shrink)

This book examines the social and philosophical attitudes in Western culture that relate to the environment including aesthetics, wildlife, and land use. Both the historical significance and a framework for further discussions of environmental ethics are discussed in the book.

Revealing flaws in both 'green' and market-based approaches to environmental policy, O'Neill develops an Aristotolian account of well-being. He examines the implications for wider issues involving markets, civil society an.

Professional environmental ethics arose directly out of the interest in the environment created by Earth Day in 1970. At that time many environmentalists, primarily because they had read Aldo Leopold’s essay, “The Land Ethic,” were convinced that the foundations of environmental problems were philosophical. Moreover, these environmentalists were dissatisfied with the instrumental arguments based on human use and benefit—which they felt compelled to invoke in defense of nature—because they thought these arguments were part of the problem. Wanting to counter instrumental (...) arguments in some way with non- or even anti-instrumental arguments, and unable to think of anything else to say, they began wistfully suggesting that perhaps nature had or ought to have rights. When professional environmental ethics came into its own in the early 1980s, rights for nature were one of the first subjects to be debated in detail. Unfortunately, however, no one could come up with a theory to support such rights attributions. Nevertheless, because rights had been invoked by environmentalists to challenge the preeminent role of instrumental value arguments, and because the field of environmental ethics developed in support of environmental concerns and arguments, environmental ethicists turned to an examination of noninstrumental or intrinsic value arguments for the preservation of nature.

Here I argue that wild nature has intrinsic value, which gives rise to obligations both to preserve it and to restore it. First, an account of intrinsic value, which permits core environmentalist claims, is outlined and defended. Second, connections between intrinsic value and obligation are discussed. Third, it is argued that wild nature has intrinsic value, in part, in virtue of its naturalness.

Environmental problems have an ethical dimension. They are not just about the efficient use of resources. Justice in the distribution of environmental goods and burdens, fairness in the processes of environmental decision-making, the moral claims of future generations and non-humans, these and other ethical values inform the responses of citizens to environmental problems. How can these concerns enter into good policy-making processes?Two expert-based approaches are commonly advocated for incorporating ethical values into environmental decision-making. One is an 'economic capture' approach, according (...) to which existing economic methods can be successfully extended to include ethical concerns. For example, stated preference methods, especially contingent valuation, have been developed to try and capture ethical responses as 'non-use values' of the environment, in particular 'existence values'. The other is a 'moral expert' approach which confines economic methods to the analysis of welfare gains, and assumes committees of ethical experts will complement economic expertise.Both approaches face problems in terms of addressing many widely held ethical values about the environment. Furthermore, both face problems concerning the democratic legitimacy of their procedures. How can policy-making be made responsive to different ethical values? What role is there for new deliberative and participatory methods? How far do existing decision-making institutions have the capacities to incorporate different modes of articulating environmental values?This policy brief examines the limitations of current attempts to capture ethical values within existing economic instruments and considers how these limitations might be overcome. Section 1 examines the assumptions that standard economic theory makes about individuals when they express values and make choices about the environment. The current models of agents that inform policy-making are seen to be ill-suited to incorporating the ethical responses of agents and this reveals some of the policy failures that may result. Section 2 shows how the physical and social properties of many environmental goods prevent their being treated as commodities. Section 3 considers the problems surrounding conceptions of fairness and legitimacy in processes for environmental valuation. Section 4 raises questions concerning the capacities of policy-making institutions to take cognisance of the results of different methods for articulating environmental values. (shrink)

This paper addresses problems related to transferring market concepts to non-market domains. More specifically it is about fallacies following from the use of the commodity concept in environmental valuation studies. First of all, the standard practice tends to misconstrue the ethical aspects related to environmental choices by forcing them into becoming ordinary trade-off problems. Second, the commodity perspective ignores important technical interdependencies within the environment and the relational character of environmental goods. These are all properties that have made many such (...) goods escape the commoditisation pressure of markets in the first place. Further, it is shown that these interdependencies are the source of some of the ethical dilemmas observed. Finally, inherent characteristics of the environment tend to make the concept of the margin, so indispensable to economic calculus, either difficult or irrelevant to define. The commodity 'fiction' twists the perception of the environment from systems preservation to items use or transformation. This is a problem of increased importance as we approach potential systems perturbations. (shrink)

Establishing that nature has intrinsic value has been the primary goal of environmental philosophers. This goal has generated tremendous confusion. Part of the confusion stems from a conflation of two quite distinct concerns. The first concern is with establishing the moral considerability of the natural world which is captured by what I call "intrinsic value p ." The second concern attempts to address a perceived problem with the way nature has traditionally been valued, or as many environmentalists would suggest, undervalued, (...) what I call "intrinsic value v ." In this paper I argue against further development of both types of theories of the intrinsic value of nature. There are, I believe, intermediate valuations that have been almost entirely overlooked in discussions of value. Much of the confusion currently plaguing environmental ethics can be avoided by abandoning intrinsic value and refocusing environmental ethics. (shrink)

In the literature of environmental philosophy, the single most potent argument that has been made against the claim that nature may possess intrinsic value in any objective sense is the Humean thesis of projectivism and its associated view that human consciousness is the source of all values. Theorists, in one way or another, have to face up to this challenge. For instance, J. Baird Callicott upholds this Humean foundation to modern Western philosophy. However, by distinguishing between the source and locus (...) of value, he makes it possible to argue that nature is the locus of intrinsic value without at the same time compromising the thesis that human consciousness is the source of all values. On the other hand, Holmses Rolston, III, another eminent environmental philosopher, criticizes the distinction as well as challenges the Humean foundation itself. In this article, I attempt to resolve the disagreement between Callicott and Rolston over this particular distinction, thereby doing justice to the insights which each theorist, undoubtedly, has brought to bear on the issue of intrinsic value, at least as far as individual organisms is concerned. However, I am also critical of both for having failed to draw out the full implications behind certain crucial distinctions that should be made about the notion of intrinsic value itself. (shrink)

Contingent valuation of the environment has proven popular amongst environmental economists in recent years and has increased the role of monetary valuation in public policy. However, the underlying economic model of human psychology fails to explain why certain types of stated behaviour are observed. Thus, good scope exists for interdisciplinary research in the area of economics and psychology with regard to environmental valuation. A critical review is presented here of some recent research by social psychologists in the US attempting to (...) explain stated behaviour in contingent valuation. Attitudinal scales have been used to analyse the role of ecocentric, biocentric and altruistic motives for giving. However, the research is shown to draw some potentially misleading conclusions and be unrepresentative of contingent valuation. Two recent economic studies using contingent valuation are then reported and shown to have identified non-economic motives for WTP. The complexity of value formation and expression is found to go far beyond that generally accepted by economic models. Greater consideration of the role played by attitudes and ethical considerations then becomes relevant to the interpretation of results being used in standard cost-benefit analysis and environmental policy.

The services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth's life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value is estimated to be in the range of (...) US$16-54 trillion per year, with an average of US$33 trillion per year. Because of the nature of the uncertainties, this must be considered a minimum estimate. Global gross national product total is around US$18 trillion per year. (shrink)

The paper discusses some of the criticisms of contingent valuation (CV) and allied techniques for estimating the intensity of peoples' preferences for the environment. The weakness of orthodox utilitarian assumptions in economics concerning the commensurability of all items entering into peoples' choices is discussed. The concept of commensurability is explored as is the problem of rational choice between incommensurate alternatives. While the frequent claim that the environment has some unique moral intrinsic value is unsustainable, its preservation often raises ethical and (...) other motivations that are not commensurate with the values that people place on ordinary marketable goods. Nevertheless, CV is also claimed to have some advantages and it is concluded that little progress will be made in this area until both sides in the debate recognise what is valid in their opponents' arguments.

While fraught with ambiguities, support for greater public participation in environmental policy making is experiencing a renaissance amongst sections of government and academia, particularly within the field of land-use planning. There is concern within this cohort that the planning system silences public voices through its current mechanisms for community involvement. Proponents of participation often presuppose that more public participation will produce both ‘better’ decisions and environmental benefits, but to date research has focused on the front-end, or ‘processes’, of participation rather (...) than the ‘products’ that result. While procedural aspects of public participation are important it is imperative that critical consideration is also given to what emerges from the participation that is being exalted. This paper addresses this concern by focusing on the products of a public participation exercise conducted in Luton, South-east England in order to consider what it is that ‘silence knows’. (shrink)

Contingent Valuation has been promoted as a catch-all approach to environmental valuation. While there have been numerous attempts in recent years to place monetary values on environmental amenities, studies have often reported a high frequency of protest, zero or inordinately large dollar-value responses. This paper reports on the results of a survey designed to obtain information on how people actually interpret questions of paying to avoid changes in their views of Rangitoto Island. Evidence suggests that the meaning respondents attach to (...) the actual dollar values they offer or bid are inconsistent with the conventional logic that underlies Contingent Valuation. Instead, respondents might be seen to be expressing views about how things ought to be in society, and that it is simply not right to develop Rangitoto Island. (shrink)

A Practical Companion to Ethics, Fourth Edition, is a concise and accessible introduction to the basic attitudes and skills that make ethics work, like thinking for oneself, creative and integrative problem-solving, and keeping an open mind. This unique volume illuminates the broad kinds of practical intelligence required in moral judgment, complementing the narrower theoretical considerations that often dominate ethics courses. The optimistic tone and brisk pace of the narrative provide an entertaining and intelligent guide to "everyday" morality. The fourth edition (...) features a new chapter on ethical theories; significantly revised and expanded chapters on conflicts of value and creative problem- solving in ethics; and a new concluding chapter on "Making a Difference, " which explains how students can incorporate ethical thinking and practice into their daily lives.

A recurring question about cost - benefit analysis concerns its scope. CBA is a decision-making method frequently employed in environmental policy-making, in which things which have no market price are treated as if they were commodities. They are given a monetary value, a form of price. But it is widely held that some things cannot be meaningfully priced, thus substantially limiting the scope of CBA. The aim of this paper is to test some aspects of this broad claim, focusing on (...) problems of incomparability and incommensurability. In particular, the role of rough equality as a putative form of comparison is investigated. I argue that while an assessment of the full significance of rough equality for practical decision-making awaits resolution of a number of important technical questions, it does not provide a strong enough form of comparison to support CBA.

Although much attention has been given to the role of community stakeholders in developing environmental risk- management policies, most local and national initiatives are better known for their failings than their successes. One reason for this continuing difficulty, we contend, is a reluctance to address the many difficult value trade-offs that necessarily arise in the course of creating and evaluating alternative risk- management options. In this paper we discuss six reasons why such trade-offs are difficult and, for each, present helpful (...) techniques from the decision sciences along with case study examples of successful applications.

The origins of both economic and philosophical value theory are examined and shown to be closely related. The status of neo-classical value theory is that it is internally flawed in any attempt to describe the real world. Cost-benefit analysis as it applies to the valuation of environmental agents relies upon the claim that this neo-classical theory has a particular status in optimal welfare maximisation and, therefore, suffers the same problems of internal consistency. Economic valuation of the environment is not a (...) scientific process derived from external law but a social process relying upon social agreement. Alternatives to economic valuation are considered and may possess a more plausible social base. However, all environmental valuation is at odds with beliefs based upon the existence of objective and intrinsic values. (shrink)

It is widely held that all hope for a satisfactory environmental ethic rests on the question whether intrinsic value can be discovered in non-human nature, for it is also widely held that intrinsic value is what, if anything, grounds human obligations to non-human nature. The work of J. Baird Callicott on intrinsic value has been central to the contemporary discussion of environmental ethics and the present paper leads off with an overview of some aspects of his work in this area.
