It is helpful to present the deficiencies of anarchism as a theory not by stressing its exceedingly skimpy and implausible conception of the causal determinants of collective social life and its vicissitudes (a charge which can scarcely be denied), but rather by underlining its blatantly capricious views about the incidence of trust in human social relations. … What really marks anarchism out as a political theory is the judgement that dispersed coercive power either is in itself, or would be if instantiated, or could readily be caused to become, quite sufficiently trustworthy for the living of acceptable human lives. At its most optimistic anarchism simply consists in the universalization of trust towards all humans who are not themselves bearers of concentrated coercive power.
