“Several years ago, the Foundation for Biomedical Research ran an ad campaign in support of medical experimentation on nonhuman animals. The ad featured a photograph of a group of animal rights protestors under the caption: ‘Thanks to animal research, they’ll be able to protest 20.8 years longer.’ But imagine a parallel universe in which medical research is conducted on black people, and in which an equivalent foundation employs an equivalent argument: ‘Thanks to research on black people, these white protesters will be able to protest against experimentation on black people 20.8 years longer’! Would this justify experimentation on black people? Obviously not! We would immediately reject the argument as founded on a deeply racist assumption, namely, that the costs inflicted on ‘mere’ black people are justified by the benefits produced for whites. But the original argument is founded on an equivalently speciesist assumption: that the costs inflicted on ‘mere’ animals are justified by the benefits produced for us.”

Remarks while presenting a Presidential citation http://www.presidency.ucsb.edu/ws/index.php?pid=10457 to Jonas Salk (22 April 1955)
1950s
Context: The work of Dr. Salk is in the highest tradition of selfless and dedicated medical research. He has provided a means for the control of a dread disease. By helping scientists in other countries with technical information; by offering to them the strains of seed virus and professional aid so that the production of vaccine can be started by them everywhere; by welcoming them to his laboratory that they may gain a fuller knowledge, Dr. Salk is a benefactor of mankind.
His achievement, a credit to our entire scientific community, does honor to all the people of the United States.

Science - The Endless Frontier (1945)
Context: The publicly and privately supported colleges, universities, and research institutes are the centers of basic research. They are the wellsprings of knowledge and understanding. As long as they are vigorous and healthy and their scientists are free to pursue the truth wherever it may lead, there will be a flow of new scientific knowledge to those who can apply it to practical problems in Government, in industry, or elsewhere.

" An Interview with Jane Goodall https://web.archive.org/web/20100920074838/http://www.idausa.org:80/essays/goodallinterview.html", In Defense of Animals (date unknown)
Context: Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings. They don't want to admit that they might have minds and personalities because that would make it quite difficult for them to do what they do; so we find that within the lab communities there is a very strong resistance among the researchers to admitting that animals have minds, personalities and feelings.
