Evolutionary, ecological and ethical studies are, at the same time, specific scientific disciplines and, from an historical point of view, structurally linked domains of research. In a context of environmental crisis, the need is increasingly emerging for a connecting epistemological framework able to express a common or convergent tendency of thought and practice aimed at building, among other things, an environmental policy management respectful of the planet’s biodiversity and its evolutionary potential.

The paper discusses various concepts of 'species equality' and 'species superiority' and the assumptions concerning intrinsic value on which they depend. I investigate what philosophers from the traditional deontological (Taylor and Lombardi) and utilitarian (Singer and Attfield) perspectives have meant by their claims for species equality. I attempt to provide a framework of intrinsic values that justifies one sense in which members of a species can be said to be superior to members of another species.

The first half of this paper replies to three postmodernist challenges to belief in objective intrinsic value. One lies in the claim that the language of objective value presupposes a flawed, dualistic distinction between subjects and objects. The second lies in the claim that there are no objective values which do not arise within and/or depend upon particular cultures or valuational frameworks. The third comprises the suggestion that belief in objective values embodies the representational theory of perception. In the second (...) half, a defence is offered of belief in objective intrinsic value. Objectivists hold that axiological properties supply interpersonal reasons for action for any relevant moral agent. The intrinsically valuable is understood as what there is reason to desire, cherish or foster in virtue of the nature of the state or object concerned. The concept of intrinsic value is shown to be instantiated, and defended against a range of criticisms. (shrink)

Ethicist assumptions about the causes and solutions of environmental problems are widely held within environmental philosophy. It is typically assumed that an important cause of problems are the attitudes towards the natural environment held by individuals and that problems can be solved by getting people to adopt a more ethical orientation towards the environment. This article analyses and criticises these claims. Both the highly mediated nature of the relationship between individuals and the natural environment and the pervasive pressure on firms (...) in market economies to reduce their costs provide reasons to question the ethicist assumptions.

In this paper, I criticize the view that non-conscious entities—such as plants and bacteria—have well-being. Plausible sources of well-being include pleasure, the satisfaction of consciously held desires, and achievement. Since nonconscious entities cannot obtain well-being from these sources, the most plausible source of well-being for them is the exercise of natural capacities. Plants and bacteria, for example, certainly do exercise natural capacities. But I argue that exercising natural capacities does not in fact contribute (in a non-instrumental way) to well-being. I (...) do so by presenting cases in which human beings exercise natural capacities that they do not enjoy exercising and that they do not desire (non-instrumentally) to exercise. I also argue that plausible views about fortune—how one’s well-being ranks on an appropriate scale—do not support the claim that exercising natural capacities contributes to well-being. (shrink)

Both Richard Sylvan’s trenchant critique of Deep Ecology and Warwick Fox’s illuminating reinterpretation and defence are presented and appraised. Besides throwing light on the nature and the prospects of the defence of Deep Ecology and of its diverse axiological, epistemological and metaphysical strands, the appraisal discloses the range of normative positions open to those who reject anthropocentrism, of which Deep Ecology is no more than one (and, if Fox’s account of its nature is right, may not be one at all). (...) A position intermediate between Deep Ecology and anthropocentrism is advocated, which has been called by Wayne Sumner "middle-depth environmentalism – a kind of continental shelf between the shallow and deep extremes".

Robert Nozick's experience machine thought experiment is often considered a decisive refutation of hedonism. I argue that the conclusions we draw from Nozick's thought experiment ought to be informed by considerations concerning the operation of our intuitions about value. First, I argue that, in order to show that practical hedonistic reasons are not causing our negative reaction to the experience machine, we must not merely stipulate their irrelevance (since our intuitions are not always responsive to stipulation) but fill in the (...) concrete details that would make them irrelevant. If we do this, we may see our feelings about the experience machine becoming less negative. Second, I argue that, even if our feelings about the experience machine do not perfectly track hedonistic reasons, there are various reasons to doubt the reliability of our anti-hedonistic intuitions. And finally, I argue that, since in the actual world seeing certain things besides pleasure as ends in themselves may best serve hedonistic ends, hedonism may justify our taking these other things to be intrinsically valuable, thus again making the existence of our seemingly anti-hedonistic intuitions far from straightforward evidence for the falsity of hedonism.

In the past thirty years environmental ethics has emerged as one of the most vibrant and exciting areas of applied philosophy. Several journals and hundreds of books testify to its growing importance inside and outside philosophical circles. But with all of this scholarly output, it is arguably the case that environmental ethics is not living up to its promise of providing a philosophical contribution to the resolution of environmental problems. This article surveys the current state of the field and offers (...) an alternative path for the future development of environmental ethics toward a more publicly engaged model of applied philosophy.

Anthropocentrism can intelligibly be criticised as an ontological error, but attempts to conceive of it as an ethical error are liable to conceptual and practical confusion. After noting the paradox that the clearest instances of overcoming anthropocentrism involve precisely the sort of objectivating knowledge which many ecological critics see as itself archetypically anthropocentric, the article presents the follwoing arguments: there are some ways in which anthropocentrism is not objectionable; the defects associated with anthropocentrism in ethics are better understood as instances (...) of speciesism and human chauvinism; it is unhelpful to call these defects anthropocentrism because there is an ineliminable element of anthropocentrism in any ethic at all; moreover, because the defects do not typically involve a concern with human interests as such, the rhetoric of anti-anthropocentrism is counterproductive in practice.

What types of human-animal interspecific entities are used in biomedical research? Is creating such entities morally wrong? And what do interspecifics tell us about the moral significance of species? This thesis offers an introduction to the field of human-animal interspecifics from a bioethical perspective, with a special focus on the question of speciesism.

No net loss approaches to environmental policy claim that policy should maintain aggregate levels of natural capital. Substitutability between natural assets allows losses in some assets to be compensated for by gains in others while maintaining overall levels of natural capital. This paper argues that significant goods that matter to people’s well-being will be lost through a policy of no net loss. The concepts of natural capital and ecosystem services that underpin the no net loss approach to environmental policy cannot (...) capture important dimensions of value that are central to human well-being.
