  Open questions aside, it should be clear that there are two general  ways of linking psychological justice to just action: one that  depends upon the motivational power of knowledge in particular and  the other that depends upon the early training of a wide range of  attitudes in the young. If one of these ways works, then Socrates is  entitled to argue that it is always better to be just than unjust by  showing why it is always better to have a harmonious soul.
