“Revolution can never be forecast; it cannot be foretold; it comes of itself. Revolution is brewing and is bound to flare up.”

“We are not utopians, we do not “dream” of dispensing at once with all administration, with all subordination. These anarchist dreams, based upon incomprehension of the tasks of the proletarian dictatorship, are totally alien to Marxism, and, as a matter of fact, serve only to postpone the socialist revolution until people are different. No, we want the socialist revolution with people as they are now, with people who cannot dispense with subordination, control, and "foremen and accountants".”

“Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes).”

“Čovek nikada ne može biti dovoljno radikalan.Odnosno, čovek mora biti radikalan koliko i sama stvarnost.”

“Sometimes - history needs a push.”

“All official and liberal science defends wage-slavery, whereas Marxism has declared relentless war on that slavery.”
