A philosophical perspective on class-struggle anarchism in Britain today that identifies the main principles distinguishing this tradition from competing Leninist, liberal and social democratic groupings. From these key characteristics, Franks then constructs an 'ideal-type' of anarchism against which the theory and practice of contemporary groups are assessed. All the recurring concerns of anarchism are subjected to his scrutiny: the nature of the revolutionary subject; workplace and community organising; violence and the meaning of direct action.
