Today, Karl Kautsky is mainly remembered for his polemics against the young Bolshevik regime or as the ‘renegade’ in Lenin’sThe Proletarian Revolution and the Renegade Kautsky, which pillories him for his wavering stance in opposing World War I and his outright hostility to the Russian Revolution of October 1917. Kautsky’s authority as a Marxist theoretician was seriously called into question ever since Lenin’s polemic. During the Cold War in particular, a consensus emerged which suggested that Kautsky’s views of democracy, organisation (...) and revolutionary change had little or nothing to do with the political practice of Russian Bolshevism and the Russian Revolution of 1917. Recently, however, several studies have challenged this consensus. They highlight the profound impact which Kautsky had on the development of Russian Bolshevism and make the case that – prior to his renegacy in 1914 – thinkers such as Lenin and Trotsky viewed Kautsky as the legitimate intellectual heir of Marx and Engels. This article introduces an autobiographical essay written by Kautsky in 1924 and calls for closer engagement with his œuvre as a whole. (shrink)
