To study animal welfare empirically we need an objective basis for deciding when an animal is suffering. Suffering includes a wide range ofunpleasant emotional states such as fear, boredom, pain, and hunger. Suffering has evolved as a mechanism for avoiding sources ofdanger and threats to fitness. Captive animals often suffer in situations in which they are prevented from doing something that they are highly motivated to do. The an animal is prepared to pay to attain or to escape a situation (...) is an index ofhow the animal about that situation. Withholding conditions or commodities for which an animal shows (i.e., for which it continues to work despite increasing costs) is very likely to cause suffering. In designing environments for animals in zoos, farms, and laboratories, priority should be given to features for which animals show inelastic demand. The care ofanimals can thereby be based on an objective, animal-centered assessment of their needs. (shrink)

How should a philosophical inquiry into the moral status of (nonhuman) animals proceed? Many philosophers maintain that by examining the “morally relevant” psychological or physiological capacities possessed by the members of different species, and comparing them with similar capacities possessed by human beings, the moral status of the animals in question can be established. Others contend that such an approach runs into serious moral and conceptual problems, a crucial one being that of how to give a coherent account of the (...) natural sense of concern for profoundly cognitively impaired human beings if moral status is assumed to depend on features that centrally include cognitive capacities. The present article discusses this debate with reference to Wittgenstein-influenced philosophers whose respective approaches, on the face of it, diverge dramatically. With a primary focus on Hans-Johann Glock and Cora Diamond, and a secondary focus on recent work by Alice Crary, I argue that, despite an overt disavowal of the kind of approach favoured by Diamond and Crary, Glock’s affirmation that we simply do “value human life” brings him closer to that approach than he acknowledges.

Cost-benefit analysis makes the assumption that everything from consumer goods to endangered species may in principle be given a value by which its worth can be compared with that of anything else, even though the actual measurement of such value may be difficult in practice. The assumption is shown to fail, even in simple cases, and the analysis to be incapable of taking into account the transformative value of new experiences. Several kinds of value are identified, by no means all (...) commensurable with one another – a situation with which both economics and contemporary ethical theory must come to terms. A radical moral pluralism is recommended as in no way incompatible with the requirements of rationality, which allows that the business of living decently involves many kinds of principles and various sorts of responsibilities. In environmental ethics, pluralism offers the hope of reconciling various rival theories, even if none of them is universally applicable. (shrink)

Traditional approaches to animal ethics commonly emerge from one of two influential ethical theories: Regan’s deontology (The case for animal rights. University of California, Berkeley, 1983) and Singer’s preference utilitarianism (Animal liberation. Avon Books, New York, 1975). I argue that both of the theories are unsuccessful at providing adequate protection for animals because they are unable to satisfy the three conditions of a minimally decent theory of animal protection. While Singer’s theory is overly permissive, Regan’s theory is too restrictive. I (...) argue that a minimally decent animal ethic requires a framework that allows for context-dependent considerations of our complex human–animal relationship in a non-ideal world. A plausible theory which exemplifies this new ethic is virtue ethics. (shrink)

In this paper I will examine two responses to the argument from marginal cases; the argument from kinds and the similarity argument. I will argue that these arguments are insufficient to show that all humans have moral status but no animals do. This does not prove that animals have moral status but it does shift the burden of proof onto those who want to maintain that all humans are morally considerable, but no animals are.

En este artículo se explica en qué consisten las éticas centradas en el sufrimiento, presenta algunas de las principales razones a su favor y expone cuáles son sus implicaciones con respecto a la consideración moral de los animales. Se argumenta que conforme a estas éticas los usos como recursos de los animales lesivos para estos deberán ser rechazados. A continuación, se examinan las posiciones que aceptan el uso de los animales siempre que este tenga lugar reduciendo los daños infligidos a (...) estos. Se presentarán una serie de razones por las que tales posiciones resultan cuestionables y por las que van a entrar en conflicto con las implicaciones de las éticas centradas en el sufrimiento.

In this paper I will argue that Regan’s subjects-of-a-life account is epistemically irresponsible. Firstly, in making so many epistemic claims. Secondly in making the claims themselves.

This is an essay about ethics and environmental responsibility. The thesis is that biologic species qua species--not only as collections of individuals or as elements of ecosystems--deserve moral regard. The argument establishes moral considerability on powers and freedoms of relative self-determination and autonomy. It is argued that species are living beings in their own right with their own projects and interests which deserve special regard. The essay draws from the arguments of Plato, Aristotle, Plotinus, Boethius, Avicenna, Maimonides, Leibniz, Spinoza, Kant, (...) and others, concerning the moral value of natural beings, but situates itself in the contemporary dialogue of environmental ethics. Lengthy consideration is given to species concepts defended by evolution theorists, biological systematists, and ecologists. ;The argument claims that natural beings, including species, have moral value because they have projects and interests which make a legitimate, but not universal, claim on the moral agent. Beings make moral claims when they are integral and integrating, individual, and concreative--conditions comparable to those with which we describe the moral status of a person. We may call such beings rational by analogy to the integration and singularity of intellect, and confer upon them analogous moral consideration. They are due regard in proportion to their projects in the same sense that moral subjects are due regard for having the projects of moral subjects. (shrink)

This essay explores the moral reasoning underpinning the common view that it is worse to kill a human compared with killing an animal. After examining the serious deficiencies of traditional approaches, the author develops an alternative utilitarian-based framework that proportions the seriousness of killing to levels of sentience. He demonstrates how this new approach avoids the problems faced by the application of standard utilitarian formulae in weighing the seriousness of killing many low-sentience animals vis-á-vis killing a single human. The author (...) concludes with a discussion of how this new approach overcomes the difficulties faced by Peter Singer’s dualist form of utilitarianism. (shrink)

The moral consideration of nonhuman animals and the critique of speciesism have been defended by appeal to a variety of ethical theories. One of the main approaches in moral and political philosophy today from which to launch such a defense is egalitarianism, which is the view that we should aim at favoring the worse off by reducing inequality. This paper explains what egalitarianism is and shows the important practical consequences it has for nonhuman animals, both those that are exploited by (...) humans and those in need of aid in the wild. Egalitarianism implies rejecting speciesism, and in practice it prescribes ceasing to exploit nonhuman animals as well as assisting them. Moreover, because they are worse off in comparison to humans, egalitarianism prescribes giving priority to the interests nonhuman animals. Due to this, egalitarianism gives us extra reasons to defend them beyond those entailed by other nonspeciesist approaches. (shrink)
