'The revolution in our country is one that involves the whole people, says the bourgeoisie to the proletariat. Therefore, you, as a separate class, must confine yourselves to your class struggle, must in the name of “common sense” devote your attention mainly to the trade unions, and their legalisation, must consider these trade unions as “the most important starting point in your political education and organisation,” must in a revolutionary situation draw up for the most part “serious” resolutions like the new Iskra resolution, must pay careful heed to resolutions that are “more favourably inclined towards the liberals,” must show preference for leaders who display a tendency to become “practical leaders of the real political movement of the working class,” must “preserve the realistic elements of the Marxian world outlook” (if you have unfortunately already become infected with the “strict formulae” of this “unscientific” catechism).
'The revolution in our country is one involving the whole people, Social-Democracy says to the proletariat. Therefore, you, as the most progressive and the only thoroughly revolutionary class, must strive not only to take the most active part, but also the leading, part in it. Therefore, you must not confine yourselves to narrowly conceived limits of the class struggle, meaning mainly the trade union movement, but, on the contrary, you must strive to widen the limits and the content of your class struggle to include not only all the aims of the present, democratic, Russian revolution of the whole of the people, but the aims of the subsequent socialist revolution as well. Therefore, while not ignoring the trade union movement, while not refusing to take advantage of even the slightest legal possibilities, you must, in a revolutionary period, put in the forefront the tasks of armed insurrection and the formation of a revolutionary army and a revolutionary government as being the only way to the complete victory of the people over tsarism, to the winning of a democratic republic and real political liberty.'
