The Social-Democrat’s ideal should … be the tribune of the people, who is able to react to every manifestation of tyranny and oppression, no matter where it appears, no matter what stratum or class of the people it affects; who is able to generalize all these manifestations and produce a single picture of police violence and capitalist exploitation; who is able to take advantage of every event, however small, in order to set forth before all his socialist convictions and his democratic demands, in order to clarify for all and everyone the world-historic significance of the struggle for the emancipation of the proletariat.
