For I spend all my time going about trying to persuade you, young and old, to make your first and chief concern not for your bodies nor for your possessions, but for the highest welfare of your souls, proclaiming as Igo,Wealth does not bring goodness, but goodness brings wealth and every other blessing, both to the individual and to the state.
