secondly, it never corresponded to the disagreement between the materialists and the Machists, for the Machist Bazarov, for example, was with me in opposing the boycott and wrote a long article on this in Proletary ).
To hinder the application of the tactics of revolutionary Social-Democracy in the workers' party for the sake of disputes on the question of materialism or Machism, would be, in my opinion, unpardonable folly. We ought to fight over philosophy in such a way that Proletary and the Bolsheviks, as a faction of the party, would not be affected by it. And that is quite possible.
And you, I think, ought to help in this. You can help by contributing to Proletary on neutral questions (that is, unconnected with philosophy) of literary criticism, publicism, belles lettres, and so on. As for your article, if you wish to prevent a split and help to localise the new fight -- you should rewrite it, and everything that even indirectly bears on Bogdanov's philosophy should be placed somewhere else. You have other mediums, thank God, besides Proletary. Everything that is not connected with Bogdanov's philosophy -- and the bulk of your article is not connected with it -- you could set out in a series of articles for Proletary. Any other attitude on your part, that is, a refusal to rewrite the article or to collaborate with Proletary would, in my opinion, unavoidably tend to aggravate the conflict among the Bolsheviks, make it difficult to localise the new fight, and weaken the vital cause, so essential practically and politically, of revolutionary Social-Democracy in Russia.
That is my opinion. I have told you all my thoughts and am now looking forward to your reply.
We intended to go to you today, but find that we have to postpone our visit for not less than a week, perhaps two or three weeks.
With very best regards,
Yours, N. Lenin
