"A gem of a book for scholars in race and ethnic relations and sociobiology. . . . Van den Berghe analyzes various forms that race and ethnic relations have displayed including colonial empires, slavery, middleman minorities, caste systems, and assimilation. The causes and consequences of these systems are brilliantly teased out employing historical and crosscultural examples. Libraries with any work at all on race and ethnic relations or sociobiology should acquire this book." Choice
