81:6.1

While biologic evolution has proceeded ever upward, much of cultural evolution went out from the Euphrates valley in waves, which successively weakened as time passed until finally the whole of the pure-line Adamic posterity had gone forth to enrich the civilizations of Asia and Europe. The races did not fully blend, but their civilizations did to a considerable extent mix. Culture did slowly spread throughout the world. And this civilization must be maintained and fostered, for there exist today no new sources of culture, no Andites to invigorate and stimulate the slow progress of the evolution of civilization.
