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.
