The basic mistake of those who polemicise against What is to be Done? today, is that they tear this work completely out of the context of a definite historical milieu, a definite, now already long-past period of development of our party ... To speak at present about the fact that Iskra (in the years 1901 and 1902!) exaggerated the idea of the organisation of professional revolutionists, is the same as if somebody had reproached the Japanese, after the Russo-Japanese war, for exaggerating the Russian military power before the war, for exaggerated concern over the struggle against this power. The Japanese had to exert all forces against a possible maximum of Russian forces in order to attain the victory. Unfortunately. many judge from the outside, without seeing that today the idea of the organisation of professional revolutionists has already attained a complete victory. This victory, however, would have been impossible if, in its time, this idea had not been pushed into the foreground, if it had not been preached in an “exaggerated” manner to people who stood like obstacles in the way of its realisation ... What is to be Done? polemically corrected Economism, and it is false to consider the contents of the brochure outside of its connection with this task.
