A high-energy conversation ranging from conservatives' views on environmental pollution, to population control in the Philippines, to Middle Americans' embrace of Spiro Agnew, to the Church's understanding that even saints are also sinners.

So far there is no unique action of which Mr. Nixon is the author."
