 Such sweeping generalizations are difficult to support. Thus anarchism as political philosophy faces the challenge of specificity. States have been organized in various ways. Political power is not monolithic. Sovereignty is a complicated matter that includes divisions and distributions of power (see Fiala 2015). Moreover, the historical and ideological context of a given anarchist’s critique makes a difference in the content of the political anarchist’s critique. Bakunin was responding primarily to a Marxist and Hegelian view of the state, offering his critique from within the global socialist movement; Casey is writing in the Twenty-First Century in the era of liberalism and globalization, offering his critique from within the movement of contemporary libertarianism. Some anarchists engage in broad generalizations, aiming for a total critique of political power. Others will present a localized critique of a given political entity. An ongoing challenge for those who would seek to understand anarchism is to realize how historically and ideologically diverse approaches fit under the general anarchist umbrella. We look at political anarchism in detail below.
