Some of the people on this site sure do seem to be able to make a giant mess out of an argument. The fact that the people who constructed the first prototype of a "dictatorship of the proletariat" were not "Marxists" would not be a good reason for Marx to not embrace it. Unlike a great many of his modern day groupies (and evidently some of his anti-groupies) that was not one of his criteria.The problem with the Russian Revolution was not the "totalitarian" proclivities of Lenin but the backward structure of the Russian economy in 1917. You can't have a "dictatorship of the proletariat" emerge from a dual revolution where the workers are only a tiny minority of the population no matter how much you "will" it.
The "dictatorship of the proletariat" is the rule of the whole society by the workers. This will only work when the vast majority of the people are working class.
Alexander, I think this is the second post you've made that I've substantially agreed with... though I'm a bit worried that I might be agreeing with the words not the meaning behind them.
I agree that 'the problem' was not "totalitarian proclivities" because I believe even if Lenin had been as wise as Buddha and as lovely as Joanna Lumley (who is lovely), Russia as an isolated state would still have succumbed to a brutal dictatorship; anything else is impossible without world revolution. Even if the 'Russian revolution' had instead occurred in Germany or Britain (where there were many more proletarians, in Britain certainly a majority) the 'dictatorship of the proletariat' would have succumbed to counter-revolution. The 'dictatorship of the proletariat' must be worldwide or it will succumb. Simple as that. There are no 'national revolutions'. There are just territorial expressions of the world revolution.
Good point RedEd.
