Our object in the construction of the state is the greatest happiness of the whole, and not that of any one class.
PlatoPeople are like dirt. They can either nourish you and help you grow as a person or they can stunt your growth and make you wilt and die.
PlatoWhen a person supposes that he knows, and does not know; this appears to be the great source of all the errors of the intellect.
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.
Plato
