Few Marxist philosophers and thinkers have been analysed and discussed as much as Rosa Luxemburg, and this has often been in a hostile or dishonest way. Some falsely condemned her as a believer in spontaneity and of the almost teleological inevitability of socialism. Others have tried to subsume her writings into those of liberalism with her assertion of the importance of democracy and freedom of speech. The late Professor Geras does her legacy a great service by dispelling both of these myths, and using close textual analysis and comparison with other revolutionaries such as Trotsky and Lenin, shows that she was a dedicated Marxist revolutionary whose critiques of capitalism were combined with an unfailing belief that only through constant agitation and rigorous self-education could the masses seize political and economic power following the economic collapse that she believed was inevitable. However, she knew that within a genuinely democratic and socialist society, based on the Marxist principe of self-realisation and expression, a recourse to police-state tactics, of repression, of death-squads and censorship and authoritarianism, would lead to the decay and death of that society. Had she not been so brutally murdered in 1919 by the fascists she had spent her political life fighting, she would have lived to have seen that she was more right than she knew.
