Thanks to Jim Bronskill of the Canadian Press, we now know that the RCMP kept a classified dossier on Frye between 1960 and 1972. Here he is on privacy and the free mind:

If certain tendencies within our civilization were to proceed unchecked, they would rapidly take us towards a society which, like that of a prison, would be both completely introverted and completely without privacy. The last stand of privacy has always been, traditionally, the inner mind. . . A society entirely controlled by slogans and exhortations would be introverted, because nobody would be saying anything; there would only be echo, and Echo was the mistress of Narcissus. It would also be without privacy because it would frustrate the effort of the healthy mind to develop a view of the world which is private but not introverted, accommodating itself to opposing views.
