In Secrets of the Great Egyptians, Peter Thompkins tells us that the Khemetic people of Africa (ancient Egyptians) originated "Phi" as a symbol of the creative function of the male reproductive system and more loosely as "reproduction in endless series". It was a symbolic representation of "the fire of life". This symbol of fertility was adopted in our name to stand for our continual growth and development. Our Phi should in no way be confused with the greek symbol “Phi”, which takes on the same look but a totally different meaning.
