Philosophy's role in the ethical problems of interdisciplinary research is more interestingly  metaethical than ethical in the standard sense. When we speak of philosophers directing the ethical dimensions of a project, we think of what ought and what ought not to be done. Often more challenging are questions about what we are doing when we are examining ethical questions, about what such questions mean and imply. I have identified four ethical issues involved in research of the sort we are now undertaking. I have tried to articulate the issues and to explain the insights that motivate the arguments.Often we accomplish more by raising a question clearly and showing its importance, than by providing answers. I attempt here to raise some questions that we can usefully keep in view in this project.
