I moved this here because it's really a pretty huge digression from the thread topic, but I think it's an interesting discussion.
I have a great deal of respect for Bertrand Russell, as does (I must presume)
@Jack V Savage. But his mislabeling of Lenin was pretty glaring. He referred to him as, though a generationally "great" man, a narrowly focused and rigid ideologue who was propelled to his station by his being a superior diplomat and administrator than his contemporaries. This is in star contrast to the portrayal of Lenin by Kropotkin, who held Lenin as a sort of apolitical tyrant.
Both were incorrect, but Kropotkin was probably closer, and I think the two views have been synthesized accurately by Noam Chomsky (who I frankly hold in higher intellectual regard than Russell, Lenin, or Kropotkin) who describes Lenin as a right-wing distortion of the Russian communist movement. Lenin was no sort of ideologue in the least, and his Marxian applications differed greatly in his life, both theoretically and in practice. To this end, he was a sort of ideological reactionary in that he never held fast to the brilliance of State and Revolution. However, he was also no great administrator: that was Trotsky. Lenin was brilliant and ruthless, but he was also lacking in organization.
