It is, then, the duty of a young man to show deference to his elders and to attach himself to the best and most approved of them, so as to receive the benefit of their counsel and influence. For the inexperience of youth requires the practical wisdom of age to strengthen and direct it. And this time of life is above all to be protected against sensuality and trained to toil and endurance of both mind and body, so as to be strong for active duty in military and civil service. And even when they wish to relax their minds and give themselves up to enjoyment they should beware of excesses and bear in mind the rules of modesty. And this will be easier, if the young are not unwilling to have their elders join them even in their pleasures.
(2) age,
123 The old, on the other hand, should, it seems, have their physical labours reduced; their mental activities should be actually increased. They should endeavour, too, by means of their counsel and practical wisdom to be of as much service as possible to their friends and to the young, and above all to the state. But there is nothing against which old age has to be more on its guard than against surrendering to feebleness and idleness, while luxury, a vice in any time of life, is in old age especially scandalous. But if excess in sensual indulgence is added to luxurious living, it is a twofold evil; for old age not only disgraces itself; it also serves to make the excesses of the young more shameless.
124 At this point it is not at all irrelevant to discuss the duties of magistrates, of private individuals, [of native citizens,] and of foreigners.
(3) magistrates,
It is, then, peculiarly the place of a magistrate to bear in mind that he represents the state and that it is his duty to uphold its honour and its dignity, to enforce the law, to dispense to all their constitutional rights, and to remember that all this has been committed to him as a sacred trust.
(4) private citizens,
The private individual ought first, in private relations, to live on fair and equal terms with his fellow-citizens, with a spirit neither servile and grovelling nor yet domineering; and second, in matters pertaining to the state, to labour for her peace and honour; for such a man we are accustomed to esteem and call a good citizen.
(5) aliens.
125 As for the foreigner or the resident alien, it is his duty to attend strictly to his own concerns, not to pry into other people's business, and under no condition to meddle in the politics of a country not his own.
