In this chapter, I argue that medicine is not science. Medicine is care and not research, and medical science is research, not care. Medicine is done by doctors, nurses, and so on; medical science is done by pharmacologists, microbiologists, epidemiologists, etc. Medicine and science are completely separate activities; they do not overlap. While some doctors are also scientists, their work in the lab and in the clinic does not overlap. I suggest keeping medicine and science separate until we have more and better arguments in support of the notion that doing medicine and doing science are the same.
