The “Metaphor of War” and Research Since the beginning of the 1880s, when the identification of bacteria as agents of disease occurred, the metaphor of a “war” against illness and suffering has been popular and widely employed. Cancer cells “invade” the body, “war stories” are a feature of “life in the trenches” of medicine, and the constant hope is for a “magic bullet” that will cure disease in an instant. Lying behind the “metaphor of war” is the notion of an insistent, undeniable, moral obligation to carry out research aiming to cure, or at least to reduce, the suffering and the diseases which invade our mind and body. Since there are surely many features of medicine that may be compared to war, the metaphor is not implausible, and it has proven to be frequently useful in the political effort to gain money for research. Historically, there can be little doubt that one of the main objectives of medicine has been the relief of pain and suffering, and it has always been considered a worthy and highly defensible objective. The same can be said of medical research that aims to implement that same objective. It is a valid and valuable goal, deserving of public support. From a moral point of view it is hard to argue with the idea that, as human beings, we should do what we can to relieve the human condition of avoidable diseases and disability. Research has proven to be a superbly valid way of doing that. .
