Written in the aftermath of the Second Congress of the RSDLP from which was birthed the Bolshevik-Menshevik split or, as Lenin here puts it, the divide into "revolutionary" and "opportunist" wings, this book can be considered as a kind of sequel to Lenin's much more famous earlier work What is to be Done?, for it is here that Lenin builds upon the concept of vanguard party of the most educated, class conscious, dedicated elements of the proletariat as the general staff of the proletarian class first laid down in the aforementioned book and the article Where to Begin?, and sums up the experience of the newspaper Iskra in constructing the party.
Of primary significance today is Lenin's summing up of the discussions at the congress over the nature of party membership, wherein Lenin explains that “a member of the party is one who accepts its programme and supports the Party both financially and by personal participation in one of the party organisations” (p. 46), with the Mensheviks taking particular exception to the latter part of Lenin's requirements for party membership. Pair this with Lenin's words on how the party should conduct itself, what role it should play, in What is to be Done?, and one gets a good picture of what kind of a person is a member of the Leninist party of the new type and the special significance of Stalin's words in his eulogy of Lenin: “we Communists are people of a special mould. We are made of a special stuff” (Works, Vol. 6, p. 47, Foreign Languages Publishing House 1953).
Another great point of importance in this work, continuing from What is to be Done?, is how Lenin defends the necessity of democratic centralism against the Mensheviks, many of whom would adopt liquidationist views in the aftermath of this congress, who, in opposition, claimed that such an order of organsiation would stifle freedom of thought and action within the party. To the contrary, and history proved this lesson very well, the lofty "freedoms" sought by the Mensheviks would spell the emergence of liquidationist, anti-party trends and, continued by many opportunists outside of Russia into the present day, totally destroy many a party.
Beyond Lenin's great lessons in organisation offered here, there is much to be learned here in the development of the Bolshevik prorgamme, particularly as regards the peasantry. Lenin would later elaborate in his The Two Tactics of Social-Democracy in the Democratic Revolution the theory of the continuation of the bourgeois-democratic revolution into socialist revolution with the proletariat being able to utilise the poor and middle peasant to form the vast reserve of the still numerically small proletariat and history, too, proved the correctness of this tactic. But it was at the second congress that this topic came to the fore: Menshevism rejected that the proletariat could and should be the leading class in the bourgeois-democratic revolution and that it should continue to the socialist revolution after the tasks of the bourgeois revolution were completed, dogmatically calling on a repitition of the bourgeois revolutions in France, America, and Britain instead. Against this, Lenin explained exactly why such a thing could not have unfolded in Russia and why it fell to the proletariat to take up the revolutionary banner and then push through to socialism.
On this point, the book prepares the reader for The Two Tactics of Social-Democracy in the Democratic Revolution by showing where these debates began and giving the reader intimate knowledge of the dying ideas of the Mensheviks who wanted to cling at the coat tails of the bourgeoisie and the thorough bloodletting Bolshevism gave the Mensheviks on these questions.
All round, this book is of deciesive importance in grasping, firstly, the Leninist party of the new type in conjunction with What is to be Done?, by summing up the experience of Iskra in building the party (as per the "Iskra plan" of building the party around the newspaper) and clarifying the basis of party membership and duties against the Menshevik objections. And, secondly, in this book the reader is given a first-hand picture of the development of the Bolshevik programme on the eve of the 1905 Revolution and how plans were made to bring this line into practice during that revolution and, subsequently, the October Revolution. Needless to say, one should read What is to be Done? as well Where to Begin? and the Draft Declaration of the Editorial Board of Iskra before reading this book, and a could book to follow this with, I think, would be The Two Tactics.... To conclude, a book of great importance which no one can themselves a Leninist without having familiarised themselves with.
