In our time only a party that will organise really nation-wide exposures can become the vanguard of the revolutionary forces. The word “nation-wide” has a very profound meaning. The overwhelming majority of the non-working-class exposers (be it remembered that in order to become the vanguard, we must attract other classes) are sober politicians and level-headed men of affairs. They know perfectly well how dangerous it is to “complain” even against a minor official, let alone against the “omnipotent” Russian Government. And they will come to us with their complaints only when they see that these complaints can really have effect, and that we represent a political force. In order to become such a force in the eyes of outsiders, much persistent and stubborn work is required to raise our own consciousness, initiative, and energy. To accomplish this it is not enough to attach a “vanguard” label to rearguard theory and practice.

But if we have to undertake the organisation of a really nationwide exposure of the government, in what way will then the class character of our movement be expressed? — the overzealous advocate of “close organic contact with the proletarian struggle” will ask us, as indeed he does. The reply is manifold: we Social-Democrats will organise these nation-wide exposures; all questions raised by the agitation will he explained in a consistently Social-Democratic spirit, without any concessions to deliberate or undeliberate distortions of Marxism; the all-round political agitation will be conducted by a party which unites into one inseparable whole the assault on the government in the name of the entire people, the revolutionary training of the proletariat, and the safeguarding of its political independence, the guidance of the economic struggle of the working class, and the utilisation of all its spontaneous conflicts with its exploiters which rouse and bring into our camp increasing numbers of the proletariat.
