From his obituary in the New York Times:

—“He rejected the messianic illusions of successive American administrations,” said a longtime friend, John Rielly, president emeritus of the Chicago Council on Global Affairs. “Although many American pundits consider him a liberal, he was in many respects a classic Christian conservative — one who was skeptical about liberal notions of inevitable progress and always aware of the limitations of human activity.”

—Over time he became more pessimistic, his wife, the former Carolyn Cleary, said. “He lashed out at America because he loved it, but he became sadder and sadder about the nation that was so great, yet was belittling itself. He wanted America to stay home and fix its own country.”

Eternal rest grant unto him, O Lord, and let thy perpetual light shine upon him. May the souls of the faithful departed, through the mercy of God, rest in peace. Amen.
