The conventionally accepted division between the different socialist tendencies is if they are revolutionary or reformist. The former believing that it is the states responsibility for society's administration either through a proletarian dictatorship or by elected representatives. But a libertarian socialism can be regarded in many different ways - as anarchism, or as libertarian communism according to Kropotkin's thoughts. What is specific for syndicalism is the view on workers unions as a means both for revolution and the administration of production.
Syndicalism is therefore a libertarian socialism but also something more.
The defeat of capitalism demands class consciousness and the capability to fight, but to build up a free society the individuals personal sense of responsibility is more important. Only syndicalism unites both these elements.
