>From this perspective it is natural that anarchism be marked by
spontaneity, differentiation, and experimentation that it be marked by
an expressed affinity with chaos, if chaos is understood to be what
lies outside or beyond the dominant game or system. Because of the
resistance to definition and categorisation, the anarchist principle
has been variously interpreted as, rather than an articulated
position, “a moral attitude, an emotional climate, or even a mood”.
This mood hangs in dramatic tension between utopian hope or dystopian
nihilism...
