The cruel experimenter cannot be allowed to have it both ways. He cannot, in the same breath, defend the scientific validity of vivisection on the grounds of the physical similarities between man and the other animals, and then defend the morality of vivisection on the grounds that men and animals are physically different. The only logical alternatives for him are to admit he is either pre-Darwinian or immoral. - Richard D. Ryder, English scientist, Author

Vivisection is anti-science and anti-health, and is leading us down a path of waste and decay! I encourage people to fight the dangerous dead-end of animal experimentation. - Murray Cohen, MD, Founding co-chair of the Medical Research Modernization Committee.

When evaluated on the basis of real usefulness to humanity, "scientific research on Animals" is a fraud, whether intentional or not. - William A. Cave, Late President of AAVS

It took me a couple of years reading the vivisectors' own literature to convince me that animal experiments have no scientific relevance to human health anyway. - Chris DeRose, founder, Last Chance for Animals

Results from animal tests are not transferable between species, and therefore cannot guarantee product safety for humans...In reality these tests do not provide protection for consumers from unsafe products, but rather they are used to protect corporations from legal liability. - Herbert Gundersheimer, M.D., Baltimore 1988

Animal studies are done for legal reasons and not for scientific reasons. The predictive value of such studies for men is meaningless. - Dr. James D. Gallagher, Journal of the AMA 3/14/1964

During the last 80+ years, scientists experimenting on trillions of animals, came up with 900 ways of causing cancer in a mouse...BUT NO CURE TO HUMANS! - J. F. Brailsford, MD

We have cured mice of cancer for decades - and it simply didn't work in humans. - Dr. Richard Klausner, of the National Institute of Cancer

What good does it do you to test something (a vaccine) in a monkey? You find five or six years from now that it works in the monkey, and then you test it in humans and you realize that humans behave totally differently from monkeys, so you’ve wasted five years. - Dr. Mark Feinberg, a leading AIDS researcher

Giving cancer to laboratory animals has not and will not help us to understand the disease or to treat those persons suffering from it. - Sabin Albert, MD, A physician and microbiologist. Developed a live-virus polio vaccine that helped curb the spread of the then deadly disease.

About 40 per cent of all procedures used some form of anaesthesia to alleviate the severity of the interventions. For many of the remaining procedures the use of anaesthesia would have increased the animal welfare cost of the procedure. - Coalition for medical progress website – 4.2.06, www.medicalprogress.org

...many vivisectors still claim that what they do helps save human lives. They are Lying. The truth is that animal experiments kill people, and animal researchers are responsible for the deaths of thousands of men, women and children every year. - Dr. Vernon Coleman, English doctor

There are only two categories of doctors and scientists who are not opposed to vivisection: Those who don’t know enough about it and those who make money from it. - Werner Hartinger, Chief Surgeon, W. Germany, 1988

An animal experiment cannot be justifiable unless the experiment is so important that the use of a brain-damaged human would be justifiable. - Peter Singer, Australian professor, author "Animal Liberation"

You are not handling a lump of plastic. You are handling animals with central nervous systems that feel pain and suffering. - Janice Swanson, Animal behavior specialist at Kansas State University

Ask the experimenters why they experiment on animals, and the answer is: “Because the animals are like us.” Ask the experimenters why it is morally OK to experiment on animals, and the answer is: “Because the animals are not like us.” Animal experimentation rests on a logical contradiction. - Dr. Charles R. Magel, Prof. of Ethics, Moorhead St. Univ.

At present it is a rare person that emerges from medical training with his or her humanity intact. - Journal of the American Medical Association, Vol 261, p. 2011

Doctors who speak out in favour of vivisection do not deserve any recognition in society, all the more so since their brutality is apparent not only during such experiments, but also in their practical medical lives. They are mostly men who stop at nothing in order to satisfy their ruthless and unfeeling lust for honours and gain. - Hugo Knecht, Ear, Nose, Throat Specialist, Linz, October 5, 1909

I do not believe that any of the suffering I have caused to laboratory animals has helped humanity in the slightest. - Richard D. Ryder, English scientist, Author

It (referring to dog labs) did more to damage my identity as a physician than anything else. I learned nothing physiological. I learned that life is cheap, and that misery can be ignored. - Murray Cohen, MD, Founding co-chair of the Medical Research Modernization Committee.

It is totally unconscionable to subject defenseless animals to mutilation and death, just so a company can be the first to market a new shade of nail polish, or a new improved laundry detergent. - Abigail "Dear Abby" Van Buren, A well-known syndicated advice columnist and author, Testifying before Congress, 1988

Vivisection has done little for the art of the doctor at the bedside, but it has done immeasurable harm to the character and mind of the rising generation of doctors. - Dr. Rudolph Hammer, LLD

Vivisection is barbaric, useless, and a hindrance to scientific progress. - Werner Hartinger, Chief Surgeon, W. Germany, 1988

We sacrificed daily from one to three dogs, besides rabbits and other animals, and after four years experience, I am of the opinion that not one of these experiments on animals was justified or necessary. - Dr. George Hogan, student of Claude Bernard, France

What are we doing when we brainwash children in schools to cut open their fellow animals? Are we dangerously desensitizing them? Some of the most warped and blunted people I know are those who have gone through training of this sorts. - Richard D. Ryder, English scientist, Author

There will come a time when the world will look back to modern vivisection in the name of Science, as they do now to burning at the stake in the name of religion. - Dr. Henry J. Bigelow, Boston surgeon, pioneer in use of ether

I had bought two male chimps from a primate colony in Holland. They lived next to each other in separate cages for several months before I used one as a (heart) donor. When we put him to sleep in his cage in preparation for the operation, he chattered and cried incessantly. We attached no significance to this, but it must have made a great impression on his companion, for when we removed the body to the operating room, the other chimp wept bitterly and was inconsolable for days. The incident made a deep impression on me. I vowed never again to experiment with such sensitive creatures. - Dr. Christian Barnard, Performed first open heart transplant

Mayo, son of co-founder of the Mayo Clinic, a skilled surgeon and a member of the Mayo Clinic’s Board of Governors
