“…Michels' study of the German Social Democratic Party was largely a critique of the vanguardist strategy embraced by the parliamentary socialists of his day, who, in claiming to represent the emancipatory interests of 'the masses,' felt justified in repressing dissent within their own ranks. Debate over this question has been an especially prominent feature of leftist politics over the last half-century, underlying the New Left's embrace of participatory democracy and the extra-parliamentary stance of many of the so-called New Social Movements in the postwar era (Breines, 1980(Breines, , 1982Epstein, 1991;Katsiaficas, 1997), and playing a central role in the factionalization of the German Green Party (Markovits and Gorski, 1993). If we imagine that all it takes to avoid oligarchy is to remain committed to a radical agenda, no matter how undemocratic the means used by 'revolutionary' leadership might be, we bypass the question at the very heart of Michels' work and indeed, at the very heart of much of activist history since then.…”
