Literature on the mental capacities and cognitive mechanisms of the great apes has been silent about whether they can act autonomously. This paper provides a philosophical theory of autonomy supported by psychological studies of the cognitive mechanisms that underlie chimpanzee behavior to argue that chimpanzees can act autonomously even though their psychological mechanisms differ from those of humans. Chimpanzees satisfy the two basic conditions of autonomy: (1) liberty (the absence of controlling influences) and (2) agency (self-initiated intentional action), each of (...) which is specified here in terms of conditions of understanding, intention, and self-control. In this account, chimpanzees make knowledge-based choices reflecting a richly information-based and socially sophisticated understanding of the world. Finally, two major theories of autonomy (Kantian theory and two-level theory) are rejected as too narrow to adequately address these issues, necessitating the modifications made in the present approach.

The risks of harm to nonhuman primates, and the absence of benefits for them, are critically important to decisions about nonhuman primate research. Current guidelines for review and practice tend to be permissive for nonhuman primate research as long as minimal welfare requirements are fulfilled and human medical advances are anticipated. This situation is substantially different from human research, in which risks of harms to the individual subject are typically reduced to the extent feasible. A risk threshold is needed for (...) the justification of research on nonhuman primates, comparable to the way risk thresholds are set for vulnerable human subjects who cannot provide informed consent. Much of the laboratory research conducted today has inadequate standards, leading to common physical, psychological, and social harms. (shrink)

In this paper we propose a new way of conceptualizing animals in experimentation – the animal-as-patient. Construing and treating animals as patients offers a way of successfully addressing some of the entrenched epistemological and ethical problems within a practice of animal experimentation directed to human clinical benefit. This approach is grounded in an epistemological insight and builds on work with so-called ‘pet models’. It relies upon the occurrence and characterization of analogous human and nonhuman animal diseases, where, if certain criteria (...) of homology and mechanism are met, the animal simultaneously becomes a patient and a spontaneous model of the human disease.

The concept of vulnerability is deployed in bioethics to, amongst other things, identify and remedy harms to participants in research, yet although nonhuman animals in experimentation seem intuitively to be vulnerable, this concept and its attendant protections are rarely applied to research animals. I want to argue, however, that this concept is applicable to nonhuman animals and that a new taxonomy of vulnerability developed in the context of human bioethics can be applied to research animals. This taxonomy does useful explanatory (...) work, helping to pinpoint the limitations of the 3Rs/welfare approach currently adopted in the context of animal experimentation. On this account, the 3Rs/welfare approach fails to deliver for nonhuman animals in experimentation because it effectively addresses only one element of their vulnerability (inherent) and paradoxically through the institution of Animal Ethics Committees intended to protect experimental animals in fact generates new vulnerabilities that exacerbate their already precarious situation.

In the wake of the chimpanzee genome publication, Pascal Gagneux, James J. Moore and Ajit Varki consider the ethical and scientific challenges for scientists who work on captive great apes.
