“How else could respectable citizens do these things? How can they become so insensitive to what they are doing? Don Barnes, who spent sixteen years as a biomedical scientist experimenting on animals, and now heads the Washington, D.C. office of the National Anti-Vivisection Society, calls the state in which he did his work “conditional ethical blindness”” (Singer and Gruen 78-80). As a former vivisector, Barnes worked with monkeys and cut them while they were still alive. With a primary interest in the biological sciences, vivisectors performed experiments on live animals to improve understanding of anatomy, physiology, pathology, and pharmacology. These studies are just a few of the many branches of biomedical science, the combination of biology and medicine that focuses primarily on the health of both animals and humans. Animals are used as “models” to study human biology and disease to understand basic biology, and as test subjects for the development of drugs, vaccines, antibodies, and other medical treatments to improve and advance human health. As a model, scientists aim to artificially produce in a laboratory animal a condition that can resemble the human equivalent of a medical illness or injury. Scientists may have good intentions, but many do not realize that they are committing great inhumanity as they continue to exploit animals for the “greater good.” Tom Regan came to a similar conclusion: I ask myself the same kinds of questions. “Would these changes make a difference in the way I think? I would say, 'Well, since the cat lived in a larger cage, was treated kindly, and died peacefully, I no longer object to what happened to her'?" My response is always the same. I would have anyway to say about what happened to her... also... middle of paper... elmeier. "Translating research evidence from animals to humans". ): 1731-2.
