In his novel Arrowsmith, Sinclair Lewis (1885-1951) portrayed spirited characters in relation to science with a focus on scientific research aimed at fighting infectious diseases. The German character, Professor Max Gottlieb, is a bacteriologist and mentor to young Martin Arrowsmith who is much impressed by Gottlieb's dedication to pure research, and influenced by his quite unfair –for an educator– sarcastic despise for medical doctors. Dedication to the mentor will push Arrowsmith to make scientific choices while confronting human sufferings. It is because of his promise to Gottlieb that Martin Arrowsmith shall experiment on dying human beings without any doubt or even remorse, for the sake and integrity of science. Indeed a control is needed as a standard for comparison therefore only half the patients must be treated. As stated by Gottlieb, the scientist is intensely religious, he is so religious that he will not accept quarter-truths, because they are an insult to his faith. "You must pity, oh, so much the generation after generation yet to come that you can refuse to let yourself indulge in pity for the men you will see dying. … Let nothing, neither beautiful pity nor fear of your own death, keep you from making this plague experiment complete", says Gottlieb. Can experimentations on human beings be justified for answering the mere curiosity of a few scientists? Is there an adequate justification for establishing the validity of a serum before its inoculation to dying human beings? Here stands an open clash between the scientific method (need for control) and moral standards.
Martin Arrowsmith is a captivating rebel combating the force of ignorance and greed to pursue scientific truth. He is resisting pressure to become obedient, a new hero to scientific individualism. He sees external pressures from institutions, like the powerful McGurk Institute of Biology, as threat to pure science. Indeed, scientists need a great deal of freedom to pursue their educated curiosity, besides fortitude, in resisting pressure from institutions insuring their livelihood. However, his insistence in conducting 'his experiment' in the Caribbean, where plague is spreading, is quite astonishing. After becoming aware of the suffering from the plague, he "had been tempted to forget experimentation". He finds opposition among the Caribbean officials, however he carries on with experimentation until he found himself confronted with the death of his wife Leora from the plague.
Paul de Kruif, author of Microbe Hunters, contributed significantly to the elaboration of Arrowsmith. He and Lewis spent time together in the Caribbean establishing the material and characters for the novel. No doubt Paul de Kruif influenced Lewis into thinking that medicine is not a science, particularly because of lack of control experiments in medical research.1 Nevertheless, Paul de Kruif formed an opinion on experimentation with human volunteers when he wrote in Microbe Hunters, "But science is cruel, microbe hunting can be heartless, and that relentless devil that was the experimenter Walter Reed [the yellow fever hunter] kept asking: But is your experiment really sound?" Was it in the interest of science and for humanity? Yellow fever was at the time eradicated by Walter Reed and his team of brave soldiers, which prompted Paul de Kruif to acknowledge the benefit of human experimentation with volunteers.
1Lewis wrote to journalist H. L. Mencken, "The book goes grand. Paul de Kruif proves to have as much synthetic fictional imagination as he has scientific knowledge, and that's one hell of a lot. It's going to be my best book - though it isn't just mine by a long shot"At present, regulations and ethical guidelines for human experimentation exist. They stress the voluntary consent of the human subject as being 'absolutely essential', and the experiment to be such as 'to yield fruitful results for the good of society', as reported in The Ten Principles of the Nuremberg Code.
