This paper is supportive to the anthropological principle of biculturation as a pragmatic principle of education of America's contemporary ethnically-different people. The acquisition of bilingualism and a bicultural ethos are objective evidences of this process in action. Personal experiences of the author's childhood education in a Greek and American culture are detailed as a basis for development of the author's theory that educational opportunity is found in the nature of biculturation. Problems of the Science related to the basic category of ethnicity--the acquisition of speech and language--are discussed. (SHM)
