has too much gymnastic is hardened and brutalized, the gentle or philosophic temper which has too much music becomes enervated. *411* While a man is allowing music to pour like water through the funnel of his ears, the edge of his soul gradually wears away, and the passionate or spirited element is melted out of him. Too little {xlvii} spirit is easily exhausted; too much quickly passes into nervous irritability. So, again, the athlete by feeding and training has his courage doubled, but he soon grows stupid; he is like a wild beast, ready to do everything by blows and nothing by counsel or policy. There are two principles in man, reason and passion, and to these, *412* not to the soul and body, the two arts of music and gymnastic correspond. He who mingles them in harmonious concord is the true musician,--he shall be the presiding genius of our State. The next question is, Who are to be our rulers? First, the elder must rule the younger; and the best of the elders will be the best guardians. Now they will be the best who love their subjects most, and think that they have a common interest with them in the welfare of the state. These we must select; but they must be watched at every epoch of life to see whether they have retained the same opinions and held out against force and enchantment. *413* For time and persuasion and the love of pleasure may enchant a man into a change of purpose, and the force of grief and pain may compel him. And therefore our guardians must be men who have been tried by many tests, like gold in the refiner's fire, and have been passed first through danger, then through pleasure, and at every age have come out of such trials victorious and without stain, in full command of themselves and their principles; having all their faculties in harmonious exercise for their country's good. These shall receive the highest honours both in life and death. *414* (It would perhaps be better to confine the term 'guardians' to this select class: the younger men may be called 'auxiliaries.')
