We think of anarchy as being against centralised power at all costs. But, argues philosopher Melanie Erspamer, for anarchism to be effective in the world, it needs institutionalisation. What is more, our institutions need anarchism - its principles, its strategies and its values - in order to prevent problematic concentrations of power. Anarchy is an anti-power philosophy. But, paradoxically, anarchists must take positions of relative power, in order to counter the monopolistic forces of government and large corporations today.
