What is the role of the Radical?

Here from Mikhail Bakunin:

“All that individuals can do is formulate, clarify, and propagate ideas expressing the instinctive desires of the people, and contribute their constant efforts to the revolutionary organization of the natural powers of the masses. This and nothing more; all the rest can be accomplished only by the people themselves. Otherwise we would end up with a political dictatorship - the reconstitution of the State, with all its privileges, inequalities, and oppressions; by taking a devious but inevitable path we would come to reestablish the political, social, and economic slavery of the masses.”
