This paper clarifies certain issues raised by Wendell Stephenson ( The Journal of Medicine and Philosophy 18: 375–388, 1993) about research programs and animal care practices at the Oregon Regional Primate Research Center. It also responds to Stephenson's critique of the National Institute of Health's Guide for the Care and Use of Laboratory Animals . It identifies utilitarianism as the ethical theory underlying Stephenson's critique. Arguing that such an ethical theory is unworkable in addressing concerns about biomedical research and the (...) use of animals, the paper defends the Guide's reliance on a wider tradition of ethical theories.
