“The argument that the two parties should represent opposed ideals and policies, one, perhaps, of the Right and the other of the Left, is a foolish idea acceptable only to doctrinaire and academic thinkers. Instead the two parties should be almost identical, so that the American people can ‘throw the rascals out’ at any election without leading to any profound or extensive shifts in policy. . . .
But either party in office becomes corrupt, tired, unenterprising, and vigorless. Then it should be possible to replace it, every four years if necessary, by the other party, which will be none of these things but will still pursue, with new vigor, approximately the same basic policies.”
– Carroll Quigley, Tragedy and Hope: A History of the World in Our Time (New York | Macmillan | 1966)
Carroll Quigley (1910 – 1977) was an American historian and theorist of the evolution of civilizations. A professor at Georgetown University, he was renowned for his academic publications and his research on secret societies.
While a student at Georgetown’s School of Foreign Service, Bill Clinton took Pr Quigley’s course, and in 1991 he named him as an important influence on his aspirations and political philosophy.
Excerpts of Tragedy & Hope have been widely quoted by researchers of so-called “conspiracy theories”. For instance, Gary Allen quotes him profusely in None Dare Call It Conspiracy, published in 1971, and Mark Dice mentions the above quote in The New World Order: Facts & Fiction, published in 2010.
The original edition of Tragedy & Hope, published by Macmillan in 1966, sold about 8800 copies and sales were picking up in 1968 when they “ran out of stock,” Quigley wrote in a letter to Peter Sutherland, December 9, 1975. Quigley eventually learned that the publisher had destroyed the plates back in 1968, which led him to conclude that “Powerful influences in this country want me, or at least my work, suppressed.”
Author and researcher Gary North claims that in the late 1970’s, Gary Allen received an unsigned letter postmarked “Washington, D.C.” “I have seen it and the envelope,” North insists. “The sender said that he had been a friend of Quigley’s, and that at the end of his life, Quigley had concluded that the people he had dealt with in the book were not really public benefactors, as he had believed when he wrote it. According to the anonymous writer, Quigley had come to think of them in the same way that Allen did, and that Quigley had been very fearful of reprisals toward the end of his life. I believe the letter-writer,” North concluded.
