Our researches have thus yielded us twenty societies, most of them related as parent or offspring to one or more of the others: namely the Western, the Orthodox, the Iranic, the Arabic (these last two being now united in the Islamic), the Hindu, the Far Eastern, the Hellenic, the Syriac, the Indic, the Sinic, the Minoan, the Indus Culture, the Sumeric, the Hittite, the Babylonic, the Egyptiac, the Andean, the Mexic, the Yucatec and the Mayan.......Indeed it is probably desirable to divide the Orthodox Christian Society into an Orthodox-Byzantine and an Orthodox-Russian society, and the Far Eastern into a Chinese and a Korean-Japanese Society. This would raise our numbers to twenty-two; and since this book was written, a twenty third has come to light: the Shang culture that preceded the Sinic civilization, in the Yellow River Valley.
