Engels on Russia

…no more in Russia than anywhere else would it have been possible to develop a higher social form out of primitive agrarian communism unless – that higher form was already in existence in another country, so as to serve as a model. That higher form being, wherever it is historically possible, the necessary consequence of the capitalistic form of production and of the social dualistic antagonism created by it, it could not be developed directly out of the agrarian commune, unless in imitation of an example already in existence somewhere else. Had the West of Europe been ripe, 1860-1870, for such a transformation, had that transformation then been taken in hand in England, France etc., then the Russians would have been called upon to show what could have been made out of their Commune, which was then more or less intact. But the West remained stagnant, no such transformation was attempted, and capitalism was more and more rapidly developed. And as Russia had no choice but this: either to develop the Commune into a form of production from which it was separated by a number of historical stages, and for which not even in the West the conditions were then ripe – evidently an impossible task – or else to develop into Capitalism, what remained to her but the latter chance?
