No useful purpose, however, would be served in dealing with the personal phases of the struggle. Bakounin became so irate at the attacks upon him, several of which happened to have been written by Jews, that he wrote an answer entitled "Study Upon the German Jews." He feared to attack Marx; and this "Study," while avoiding a personal attack, sought to arouse a racial prejudice that would injure him. He writes to Herzen, a month after the congress at Basel, that he fully realizes that Marx is "the instigator and the leader of all this calumnious and infamous polemic."[20] He was reluctant, however, to attack him personally, and even refers to Marx and Lassalle as "these two Jewish giants," but besides them, he adds, "there was and is a crowd of Jewish pigmies."[21] "Nevertheless," he writes, "it may happen, and very shortly, too, that I shall enter into conflict with him, not over any personal offense, of course, but over a question of principle, regarding State communism, of which he himself and the English and German parties which he directs are the most ardent partisans. Then it will be a fight to the finish. But there is a time for everything, and the hour for this struggle has not yet sounded.... Do you not see that all these gentlemen who are our enemies are forming a phalanx, which must be disunited and broken up in order to be the more easily routed? You are more erudite than I; you know, therefore, better than I who was the first to take for principle: _Divide and rule_. If at present I should undertake an open war against Marx himself, three-quarters of the members of the International would turn against me, and I would be at a disadvantage, for I would have lost the ground on which I must stand. But by beginning this war with an attack against the rabble by which he is surrounded, I shall have the majority on my side.... But, ... if he wishes to constitute himself the defender of their cause, it is he who would then declare war openly. In this case, I shall take the field also and I shall play the star role."[22]
