The entire medical research enterprise is built on a foundation of intense and immense animal suffering. Most of the effective treatments we have now were previously tested on non-human animals before they were ever used on humans. On the other hand, most non-human animal research does not lead to an effective treatment or even publishable results.
In Voracious Science and Vulnerable Animals: A Primate Scientist’s Ethical Journey, John Gluck describes his glacially slow transition from primate researcher to animal welfare advocate. Early in his career, Gluck worked on the infamous monkey social-isolation experiments that provided the earth-shattering news that separating infants from their mothers and rearing them in isolation harms their emotional and intellectual development. Thanks to this ground-breaking research, mothers have learned not to raise their babies in small wire cages and occasionally perform painful surgeries on them.
In approximately the same amount of time it took for humans to evolve from other species, Gluck began to realize the great harm he was causing to his beloved monkeys. Gluck apprehended the harm he was doing after personally observing the excruciating suffering of the animals he was studying, seeing the shock in the eyes of non-scientists when he described his work and realizing that he could only describe his work to fellow scientists, having a student present him with Peter Singer’s accurate description of his work, having his lab broken into by animal rights activist, and, finally, talking with philosophers about the rights of animals.
The brilliance of his account is that he illustrates why it was so difficult for him to acknowledge the pain he was causing and why it is next to impossible to engage animal researchers in a debate over the welfare of research animals. Typically, animal researchers say they turn to non-human animals when it would be unethical to test on humans. When pressed, they will agree that animals should be used only when their use benefits the pursuit of scientific knowledge, should be given clean living quarters, should be fed appropriately, and should be given medical treatment when needed. Unless, of course, the scientist is studying the effects of food deprivation, lack of medical treatment, and so on.
The research is further justified by the fact that non-human animals have similar biological and neurological structures that ensure that results in non-human animals can be replicated in human animals. The human who doubts the similarity is scoffed at for being scientifically illiterate. Paradoxically, suggesting that non-human animals, similar to humans in other ways, are also similar to humans in terms of suffering or moral importance is accused of anthropomorphism. The argument is either that animals are not capable of suffering in any meaningful way or that their suffering is of no moral significance.
Gluck describes these arguments and explains that he himself held such seemingly contradictory views because they are taught and repeated ad nauseam until they become ingrained beginning with undergraduate study. Anyone who questions these basic beliefs is either met with laughter or denied entry and participation in research programs. People within the system become so closed off from contrary opinions that they are often surprised when descriptions of their work shocks and offends outsiders. The only explanation for the outrage many scientists will consider is that outsiders cannot understand the importance of their work.
One of the more fascinating events that led to Gluck’s change of heart concerned a human patient who was thought to be severely cognitively impaired. Staff in the patient’s room talked about the woman as if she were an object. Gluck was trying to solve a particular problem. At times, staff could feed the woman from a spoon but at other times she could not swallow. It turned out that she could swallow but was refusing to because she did not appreciate the way certain staff treated her. It was the only form of protest she had at her disposal. When Gluck realized how robust the conscious life of this patient was despite the appearance of minimal cognitive activity, he realized also that he could not say with certainty what thoughts, beliefs, or emotions non-human animals might experience.
Gluck eventually decided to get out of animal research and began teaching courses on research ethics that covered a variety of topics but included discussions of animal welfare. (If you care about the suffering of the animals in his lab, you will be disappointed by what happened to them.) Gluck’s educational programs on research ethics were successful in the sense that they attracted students from a myriad of disciplines and engaged both students and faculty in interesting and enlightening debate on the use of both human and non-human animals in research. Looking back, he is proud of his accomplishment to begin these discussions but admits that animal researchers were the one group that never engaged in the discussions.
Ethicists can attempt to change practices from inside or outside of institutions. Outsider ethicists have more freedom to make bold declarations of misconduct, express outrage, and threaten established practices. Insider ethicists have greater access and opportunity to speak directly with the people who have the power to change practices. Both kinds of ethicists are needed. Gluck is an insider whose thoughts and arguments were enhanced and supported by outsider ethicists. He says he was unable to effect a great deal of change inside research labs, but he was able to speak to researchers as an equal to engage in an ethical discussion. Sadly, insider ethicists who raise ethical alarms are often forced outside. It takes a great deal of courage to risk losing a privileged position inside the castle, and it also takes a great deal of courage to storm the castle gates.
If you are looking for a book with a detailed and comprehensive review of philosophical theory related to animals, you will be disappointed in Voracious Science and Vulnerable Animals; however, if you are looking for an insider’s perspective on the views and outlook of animal researchers, you will find Gluck’s insights and introspection fascinating, even if depressing. The book shows that it possible for researchers to be moved and gain compassion and understanding of the harm they are doing, but it also shows that such progress is slow and infrequent.
