" The philosophical assumptions, underlying values, social relations, customs, and overall outlooks on life differ significantly among civilizations. The revitalization of religion throughout much of the world is reinforcing these cultural differences. Cultures can change, and the nature of their impact on politics and economics can vary from one period to another. Yet the major differences in political and economic development among civilizations are clearly rooted in their different cultures. East Asian economic success has its source in East Asian culture, as do the difficulties East Asian societies have had in achieving stable democratic political systems. Islamic culture explains in large part the failure of democracy to emerge in much of the Muslim world. "
