The world is progressing, the future is bright and no one can change this general trend of history. We should carry on constant propaganda among the people on the facts of world progress and the bright future ahead so that they will build their confidence in victory. -- Mao Tse Tung, “On the Chungking Negotiations” (October 17, 1945), Selected Works, Vol. IV. p. 59.
The nearer we come to the full military suppression of the bourgeoisie, the more dangerous becomes to us the high flood of petty-bourgeois Anarchism. And the struggle against these elements cannot be waged with propaganda and agitation alone. … The struggle must also be waged by applying force and compulsion. -- Lenin, quoted in The Guillotine At Work : Twenty Years of Terror In Russia (1940) by Grigoriĭ Petrovich Maksimov, p. 38.
