Aaron Sloman - Asimov's Laws

Another obstacle involves potential contradictions as the old utilitarian philosophers found centuries ago: what harms one may benefit another, etc., and preventing harm to one individual can cause harm to another. There are also conflicts between short term and long term harm and benefit for the same individual. There is nothing in Asimov's formulation about how the contradictions should be resolved, though I know he and others have noticed the problems and explored some options. Major early exponents were Jeremy Bentham and John Stuart Mill, but many have challenged or tried to extend their theories, often showing up great difficulties.)
