Wherefore also these Kinds [elements] occupied different places even before the universe was organised and generated out of them. Before that time, in truth, all these were in a state devoid of reason or measure, but when the work of setting in order this Universe was being undertaken, fire and water and earth and air, although possessing some traces of their known nature, were yet disposed as everything is likely to be in the absence of God; and inasmuch as this was then their natural condition, God began by first marking them out into shapes by means of forms and numbers.
PlatoThe State which we have founded must possess the four cardinal virtues of wisdom, courage, discipline and justice ... Justice is the principle which has in fact been followed throughout, the principle of one man one job, of minding one s own business , in the sense of doing the job for which one is naturally fitted and not interfering with other people.
Plato
