" Because “pluralism is not diversity alone, but the energetic engagement with diversity,” explains the Pluralism Project at Harvard on its website, “mere diversity without real encounter and relationship will yield increasing tensions in our societies.” A society being “pluralistic” is a reality (see Syria and Iraq). A society with pluralism “is an achievement” (see America). "
