Professor Carroll Quigley, in his book Tragedy and Hope, 1966

"There does exist and has existed for a generation, an international . . . network which operates, to some extent, in the way the radical right believes the Communists act. In fact, this network, which we may identify as the Round Table Groups, has no aversion to cooperating with the Communists, or any other groups and frequently does so. I know of the operations of this network because I have studied it for twenty years and was permitted for two years, in the early 1960s, to examine its papers and secret records. I have no aversion to it or to most of its aims and have, for much of my life, been close to it and to many of its instruments. I have objected, both in the past and recently, to a few of its policies . . . but in general my chief difference of opinion is that it wishes to remain unknown, and I believe its role in history is significant enough to be known."
