"[n]o revolution can ever succeed as factor of liberation unless the MEANS used to further it be identical in spirit and tendency with the PURPOSE to be achieved." [Emma Goldman, My Disillusionment in Russia, p. 261] In other words, statist and authoritarian means will result in statist and authoritarian ends.
I wholeheartedly agree. But I think the issue goes deeper: if we want a peaceful society, it cannot be achieved through violent means. Yet can capitalist society be overcome without violence? It seems like a dead end.
