First publication of a short article in which the important political philosopher Robert Nozick - known primarily for his libertarian book 'Anarchy, State, and Utopia' (1974) - together with Richard Routley set sails to escape 'The Paradox of the Good Samaritan': ""If 'p is done' strictly implies 'q is done' then if q is forbidden then p is forbidden. (...) 'If helping a robbery victim implies a person being robbed then if the robbing is forbidden, helping the robbery victim is forbidden'"".
