From advice to fellow communists in prison and awaiting trial (in 1905):
Lawyers should be kept well in hand and made to toe the line, for there is no telling what dirty tricks this intellectualist scum will be up to. They should be warned in advance: Look here, you confounded rascal, if you permit yourself the slightest impropriety or political opportunism (if you speak of socialism as something immature or wrong-headed, or as an infatuation, or if you say that the Social-Democrats reject the use of force, speak of their teachings and their movement as peaceful, etc., or anything of the sort), then I, the defendant, will pull you up publicly, right then and there, call you a scoundrel, declare that I reject such a defence, etc. And these threats must be carried out.
