Famous quotes containing the word ideal:
“The tradition I cherish is the ideal this country was built upon, the concept of religious pluralism, of a plethora of opinions, of tolerance and not the jihad. Religious war, pooh. The war is between those who trust us to think and those who believe we must merely be led.”
—Anna Quindlen (b. 1952)
