Students intending to go to medical school should definitely take courses in biology, physics, chemistry, and mathematics. But, their major need not be a scientific one. What the AAMC recommends is a broad academic background that includes courses in the natural sciences, the social sciences, and the humanities. The philosophy major itself provides students with the reasoning and communication skills, experience in careful reading, critical judgment and analytical argument, and attention to details that is absolutely essential in the practice of medicine and most favorably judged by medical school admissions committees. The scientific knowledge that is required in the practice of medicine is the focal point of the medical school currriculum, and much scientific coursework should be completed beforehand in both high school and college.
Philosophy is recommended as just such a nonscience subject.
