American higher education contains its own erroneous nomenclature. Most notably, people having earned one degree in law or medicine are told even by their schools that the degree is doctorates. Common sense alone can point out that merely three or four years of courses in an academic discipline do not a doctorate make, especially considering that the first year or two consist of survey courses (i.e., courses that survey the different areas in a subject rather than go into depth). That having a prior bachelor’s degree is a required does not mean that the first degree in law, medicine, or divinity is advanced, for the prior degree is not in those schools (of knowledge). For instance, a person can go to a law school in America with a BA in English. Even if a person in one's first degree in medicine, the MD, has earned a prior degree in biochemistry, that subject is not medicine and thus is not relied on. I was surprised when a medical student told me that very little of even his bio-chemistry major was taught to the first-degree medical students. Hence medical students can major in different subjects without being at a disadvantage in the survey courses in the first degree in medical schools.
