Academic degree
Doctoral degrees or doctorates, such as the Doctor of Philosophy degree (PhD or DPhil) or Doctor of Education (EdD or DEd) are awarded following a programme of original research that contributes new knowledge within the context of the student's discipline. Doctoral degrees usually take three years full-time. Therefore, in the UK it may only take seven years to progress from undergraduate to doctoral level – in some cases six, since having a Master's is not always a precondition for embarking on a doctoral degree. This contrasts with nine years in the United States, reflecting differences in the educational systems.
Philosophy of education
At the age of 20, a selection was made. The best students would take an advanced course in mathematics, geometry, astronomy and harmonics. The first course in the scheme of higher education would last for ten years. It would be for those who had a flair for science. At the age of 30 there would be another selection; those who qualified would study dialectics and metaphysics, logic and philosophy for the next five years. After accepting junior positions in the army for 15 years, a man would have completed his theoretical and practical education by the age of 50.
