Injustice is censured because the censures are afraid of suffering, and not from any fear which they have of doing injustice.
PlatoAnd all knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom; wherefore make this your first and last and constant and all-absorbing aim, to exceed, if possible, not only us but all your ancestors in virtue; and know that to excel you in virtue only brings us shame, but that to be excelled by you is a source of happiness to us.
PlatoA state arises,as I conceive,out of the needs of mankind;no one is self-sufficing,but all of us have many wants
Plato
