Debates between Marxists, anarchists, and other socialists have had a profound impact on both the strategy of the international left and its vision for what a radically transformed society should look like. In many cases, these different voices agree on the desperate need to fight oppression and exploitation; but the role and meaning of terms like authority, democracy, organization, and liberation are far from clear. This talk, based heavily in anarchist writings, will delve into some of those debates and analyze some of the key ways in which anarchism is theoretically and politically unique in the socialist movement. We will look both to some of anarchism’s most prominent theorists, as well as to anarchists’ real-world interventions in movements for justice, ultimately making an argument for what ideas and strategies will best guide us toward a freer, more just world.
