Julian H. Franklin on the Use of Animals in Research

To inflict death or pain on animals for scientific or medical research is wrong morally, and ought to be prohibited. This follows from everything said in the text about the rights of animals. This does not mean that animals may never be deliberately harmed or become subjects of research. They may be killed in order to protect the health of humans (and other animals) if they are infected with a serious disease and cannot be quarantined. They may be used in benign research such as teaching chimpanzees to understand and use sign language. But even when the purpose of research is to benefit the animals themselves, inflicting pain or death in the process of research is wrong. Animals cannot give consent. Hence, unlike humans, they cannot be called upon to sacrifice even for the good of other animals.
