Abstract
Together with its kissing cousins ‘authority’ and ‘obligation’, legitimacy is a notion that should arouse apprehension. Governments that are legitimate have the ‘right to rule’, to demand obedience from their citizens or subjects. It is at least partly correct to say that this authority is independent of the content of the laws or commands issued by those invested with it, that the authority of a law or command is a reason for obeying it regardless of its contents or their merits. As widely construed, reasons of this kind are conclusive in that they leave those subject to authority with but two choices: either obey the command or disassociate from the political association of which authority is a constitutive feature. Theories of ‘passive’ and ‘civil’ disobedience add the third option of disobedience to commands judged to be unjust but on condition of peaceful submission to the penalty assigned.
