When I speak here of our policy, I use the word without regard to anything immaterial and superficial, but in the sense which since the beginning of the party it has had for us in contrast to all other parties, – in the sense of the policy of the class struggle, which has very often changed in form, but in substance has remained the same, – our unique proletarian class policy, which separates us from all other political parties in the world of bourgeois society and excludes us from intercourse with them.
