Evolution of the terminology of degrees
The naming of degrees eventually became linked to the subjects studied. Scholars in the faculties of arts or grammar became known as "masters", but those in theology, medicine and law were known as "doctors". As a study in the arts or grammar was a necessary prerequisite to study in subjects such as theology, medicine and law, the degree of doctor assumed a higher status than the master's degree. This led to the modern hierarchy in which the Doctor of Philosophy (Ph.D.), which in its present form as a degree based on research and dissertation is a development from 18th- and 19th-century German universities, is a more advanced degree than the Master of Arts (M.A.). The practice of using the term doctor for PhDs developed within German universities and spread across the academic world.
