Abstract
In book Ten of the Laws, Plato's Athenian Stranger sets out the out lines of an argument of the sort that effectively dominated thinking for several millennia about the political role of religion. A polis that is to be free from faction and free for the right development of character requires a shared understanding of the human good and of the virtues of soul that are its components; religion provides that understanding in a way that connects up the human good with the nature of the whole; as the function of government is to support civic peace and a flourishing citizenry, it must support the means thereto, namely, a civic religion; and effective support, in turn, requires state-enforced prohibitions against publicly expressed disavowals or corruptions of that dogma. Not just any dogma will do, of course, and the Stranger devotes a good deal of energy to setting out the principles of the new religion.
