"For what is it but an exquisite and priceless chance of salvation
due to God alone, that the omnipotent should deign to summon to
His service, as though they were innocent, murderers, ravishers,
adulterers, perjurers, and those guilty of every crime?"
[St. Bernard, appeal for recruits for the Second Crusade,
quoted by Brooks Adams, _The Law of Civilization and
Decay_ (New York: Alfred A. Knopf, Inc., 1943), p. 144]
