I understand, he said, and you are quite right. And you would also acknowledge that the enchanted are those who change their minds either under the softer influence of pleasure, or the sterner influence of fear? Yes, he said; everything that deceives may be said to enchant. Therefore, as I was just now saying, we must enquire who are the best guardians of their own conviction that what they think the interest of the State is to be the rule of their lives. We must watch them from their youth upwards, and make them perform actions in which they are most likely to forget or to be deceived, and he who remembers and is not deceived is to be selected, and he who fails in the trial is to be rejected. That will be the way? Yes. And there should also be toils and pains and conflicts prescribed for them, in which they will be made to give further proof of the same qualities. Very right, he replied. And then, I said, we must try them with enchantments—that is the third sort of test—and see what will be their behaviour: like those who take colts amid noise and tumult to see if they are of a timid nature, so must we take our youth amid terrors of some kind, and again pass them into pleasures, and prove them more thoroughly than gold is proved in the furnace, that we may discover whether they are armed against all enchantments, and of a noble bearing always, good guardians of themselves and of the music which they have learned, and retaining under all circumstances a rhythmical and harmonious nature, such as will be most serviceable to the individual and to the State. And he who at every age, as boy and youth and in mature life, has come out of the trial victorious and pure, shall be appointed a ruler and guardian of the State; he shall be honoured in life and death, and shall receive sepulture and other memorials of honour, the greatest that we have to give. But him who fails, we must reject. I am inclined to think that this is the sort of way in which our rulers and guardians should be chosen and appointed. I speak generally, and not with any pretension to exactness. And, speaking generally, I agree with you, he said. And perhaps the word ‘guardian’ in the fullest sense ought to be applied to this higher class only who preserve us against foreign enemies and maintain peace among our citizens at home, that the one may not have the will, or the others the power, to harm us. The young men whom we before called guardians may be more properly designated auxiliaries and supporters of the principles of the rulers. I agree with you, he said. How then may we devise one of those needful falsehoods of which we lately spoke—just one royal lie which may deceive the rulers, if that be possible, and at any rate the rest of the city? What sort of lie? he said.
