Are citizens morally obligated to obey and support their states? "Political Obligations and Authority," is perhaps A. John Simmons’ most comprehensive summary of his mature views on this enduring philosophical problem. In this essay, Simmons critically engages Plato’s dialogue Crito and culls from it three types of strategies for justifying political obligations: natural duty, associative and transactional. Simmons argues that natural duty accounts are inherently incapable of providing moral grounding for political obligations, disqualifies both associative and transactional accounts on empirical grounds and settles for a form of anarchism. I argue that, assuming as Simmons’ does in this essay that natural duties imply obligations of support and obedience to political institutions, the natural duty strategy promises to provide an escape route out of anarchism.
