In the context of academic degrees, the term "philosophy" does not refer solely to the field of philosophy, but is used in a broader sense in accordance with its original Greek meaning, which is "love of wisdom". In most of Europe, all fields other than theology, law and medicine were traditionally known as philosophy. The doctorate of philosophy as it exists today originated as a doctorate in the liberal arts at the Humboldt University of Berlin, and was eventually adopted by United States universities, becoming common in large parts of the world in the 20th century.[1] In many countries, the doctorate of philosophy is still awarded only in the liberal arts, which is known as "philosophy" in continental Europe.
