  Glaucon's ultimate aim was to get from Socrates an account of morality that — unlike his own — would serve to vindicate morality's pretensions. He assumed that if no such account was forthcoming morality's claim on our allegiance would have been undermined even as we might continue to have our own reasons for perpetuating the myth and for working to see that others comply with its rules. Much of the Republic is then given over to Socrates’ attempt to develop first an account of the nature of morality (specifically, of justice) and then, second, to arguing that being moral is valuable regardless of the consequences. Socrates' concern, in showing that being moral is valuable, is to show specifically that it is valuable to the person who is moral, that the virtuous person, and not just others, benefits from her virtue. Indeed, he tries to show that being moral is so valuable to the person who is moral, that whatever the consequences of injustice might be, however great the rewards, they could never be valuable enough to outweigh the loss of one's virtue.
