Stalin: Further, if the passing of slow quantitative changes into rapid and abrupt qualitative changes is a law of development, then it is clear that revolutions made by oppressed classes are a quite natural and inevitable phenomenon. Hence, the transition from capitalism to socialism and the liberation of the working class from the yoke of capitalism cannot be effected by slow changes, by reforms, but only by a qualitative change of the capitalist system, by revolution. Hence, in order not to err in policy, one must be a revolutionary, not a reformist. https://wordsmith.social/protestation/quotes#quote5834
