Dr. Theophile Obenga has written a great book showing the African background to Greek philosophy. The book traces the Greek student's routes when travelling to Egypt in addition to providing the words of the students themselves and their references to learning in Egypt. Dr. Obenga's mastery of ancient Greek and Medu Netcher (hieroglyphics) provides the reader with the words of the ancients themselves.
