Richard John Neuhaus was a prominent Christian cleric (first as a Lutheran pastor and later as a Roman Catholic priest) and writer. Born in Canada, Neuhaus moved to the United States where he became a naturalized United States citizen. He was the founder and editor of the monthly journal First Things and the author of several books, including The Naked Public Square: Religion and Democracy in America (1984), The Catholic Moment: The Paradox of the Church in the Postmodern World (1987), and Catholic Matters: Confusion, Controversy, and the Splendor of Truth (2006). He was a staunch defender of the Roman Catholic Church's teachings on abortion and other life issues and an unofficial advisor of President George W. Bush on bioethical issues.
A very densely argued book that talks about the long term consequences for American and world society that would follow from the application of the latest ideology of his day (ecology, population controls) to government and other aspects of society.
Having moved 50 years along in time, it's easy to see some of the long term fallout. Neuhaus was pretty accurate. Even more, many of his worries and arguments are still very applicable even if applied to more recent green and other leftist arguments for 'saving the world.'
