Plato's Definition of the Virtue of Justice

Some scholars think plato fudged the psychological argument to make it converge with the political one. But i don't think we can ever know the inner workings of any one's mind other than our own, and even that's difficult. So what do you think? Is this too pronged approach, where both paths seem to converge on the same type of answer for what justice is that convincing? Share your thoughts in the comments below or tweet us @CNNOpinion.
