As only material education is imparted and only natural philosophy is taught, these universities do not produce highly talented scholars. When both the natural and the divine philosophies are expounded, they will bring forth outstanding souls and evince great advancement. The reason for the success of the Greek schools was that they combined both natural and divine philosophies.
