The growing professional disciplines of medical ethics and bioethics have had a profound impact on researchers, bedside doctors, associations of physicians, and government.
Scientific research? Only when not at the cost of ethics-and first of all, those of the researchers themselves.
In law a man is guilty when he violates the rights of others. In ethics he is guilty if he only thinks of doing so.
Research is to see what everybody else has seen, and to think what nobody else has thought.
