Meyer Fortes' work among native people of West Africa not only contributed toward understanding of their culture, but also improved understanding of the similarities among different cultures.
By directly comparing his own religious background of Judaism with the one of Tallensi people, Fortes found numerous similarities, indicating that all religious beliefs are ultimately rooted in the same reality—God. Unification theory teaches that God is working through different religions to establish his kingdom here on Earth. Different people experience God in different ways, thus different religions; but essentially, all the religions stem from the same source. Fortes' ability to recognize the universals common to very different cultures makes his work a significant step toward reconciling separated peoples into one human family.
