In France the long expected split has taken place. The original conjunction of Guesde and Lafargue with Malon and Brousse was no doubt unavoidable when the party was founded, but Marx and I never had any illusions that it could last. The issue is purely one of principle: is the struggle to be conducted as a class struggle of the proletariat against the bourgeoisie, or is it to be permitted that in good opportunist (or as it is called in the Socialist translation: possibilist) style the class character of the movement, together with the programme, are everywhere to be dropped where there is a chance of winning more votes, more adherents, by this means. Malon and Brousse, by declaring themselves in favour of the latter alternative, have sacrificed the proletarian class character of the movement and made separation inevitable. All the better. The development of the proletariat proceeds everywhere amidst internal struggles and France, which is now forming a workers’ party for the first time, is no exception. We in Germany have got beyond the first phase of the internal struggle, other phases still lie before us. Unity is quite a good thing so long as it is possible, but there are things which stand higher than unity. And when, like Marx and myself, one has fought harder all one’s life long against the alleged Socialists than against anyone else (for we only regarded the bourgeoisie as a class and hardly ever involved ourselves in conflicts with individual bourgeois), one cannot greatly grieve that the inevitable struggle has broken out.
