“But his genetic and physical inference from cases of ethnic durability cannot account for the considerable variability, wide range and frequent absorptions and dissolutions of instances of ethnic affiliation, and the fact that many ethnies have undergone large-scale changes of culture and, in some cases, of demography. This is the case even in such a culturally long-lived example as the Greeks, where undoubted evidence of massive rupture of demographic continuity by the influx of Albanians and Slavs on the Greek mainland from the sixth to eighth centuries AD and of considerable, though not complete, culture change after the conversion to Orthodoxy, call into question the continuity and influence of a common ancient Greek biological and genetic inheritance on modern Greeks.”

“It is irrelevant in that ethnies arc constituted, not by lines of physical descent, but by the sense of continuity, shared memory and collective destiny, i. e. by lines of cultural affinity embodied in distinctive myths, memories, symbols and values retained by a given cultural unit of population. In that sense much has been retained, and revived, from the extant heritage of ancient Greece. For, even at the time of Slavic migrations, in Ionia and especially in Constantinople, there was a growing emphasis on the Greek language, on Greek philosophy and literature, and on classical models of thought and scholarship. Such a ‘Greek revival’ was to surface again in the tenth and fourteenth centuries, as well as subsequently, providing a powerful impetus to the sense of cultural affinity with ancient Greece and its classical heritage. This is not to deny for one moment either the enormous cultural changes undergone by the Greeks despite a surviving sense of common ethnicity or the cultural influence of surrounding peoples and civilizations over two thousand years. At the same time in terms of script and language, certain values, a particular environment and its nostalgia, continuous social interactions and a sense of religious and cultural difference, even exclusion, a sense of Greek identity and common sentiments of ethnicity can be said to have persisted”

“Greeks, Armenians, Jews, Persians, Chinese and Japanese could be cited as examples of ethnic continuity, since, despite massive cultural changes over the centuries, certain key identifying components—name, language, customs, religious community and territorial association—were broadly maintained and reproduced for millennia.”

“All this points to the importance of social memory; as the example of the relationship between modern and ancient Greeks shows, ethnies are constituted, not by lines of physical descent, but by the sense of continuity, shared memory and collective destiny, i. e. by lines of cultural affinity embodied in myths, memories, symbols and values retained by a given cultural unit of population.”

“Today, in the public imagination, “ethnic-cleansing” has been associated with civil war and mass murder (understandably so). But this need not be the case. 1919 is a real example of successful ethnic redistribution—done by fiat, we should remember, but done peacefully.”

“there is no cultural identity in a population without a stable ethnic composition. The alteration of a country’s ethnic makeup amounts to an alteration of its cultural identity.”

“It requires commitment, vision and will. Differences of ethnicity and multi-culturalism have to be managed and accommodated. It is a difficult balancing act, which must take account of the interests of all communities.”

“Musicals gave the U.S. an ethnic culture that undoubtedly influenced ballet.”

“Population in India is widely differentiated in ethnic composition, geographical and climatic conditions, social and cultural stratification, as well as by differences in economic status. Differential fertility therefore assumes a far more complex picture in India than anywhere in the world. Ethnic. geographical. socio-cultural and economic dilferences give a four-fold patterning with many complicated interactions. It is essential therefore to study different population groups separately.”

“This elegant generalization is mathematically very appealing; but physics means facing facts. You should take up case by case.”
