[B] Our citizens must grow up to manhood amidst impressions of grace and beauty only; all ugliness and vice must be excluded. But shall our superintendence go no further, and are the poets only to be required by us to express the image of the good in their works, on pain, if they do anything else, of expulsion from our State? Or is the same control to be extended to other artists, and are they also to be prohibited from exhibiting the opposite forms of vice and intemperance and meanness and indecency in sculpture and building and the other creative arts; and is he who cannot conform to this rule of ours to be prevented from practising his art in our State, lest the taste of our citizens be corrupted by him? We would not have our guardians grow up amid images of moral deformity, as in some noxious pasture, and there [C]browse and feed upon many a baneful herb and flower day by day, little by little, until they silently gather a festering mass of corruption in their own soul. Let our artists rather be those who are gifted to discern the true nature of the beautiful and graceful; then will our youth dwell in a land of health, amid fair sights and sounds, and receive the good in everything; and beauty, the effluence of fair works, shall [D]flow into the eye and ear, like a health-giving breeze from a purer region, and 88 insensibly draw the soul from earliest years into likeness and sympathy with the beauty of reason.
There can be no nobler training than that, he replied.
The power of imparting grace is possessed by harmony. And therefore, I said, Glaucon, musical training is a more potent instrument than any other, because rhythm and harmony find their way into the inward places of the soul, on which they mightily fasten, imparting grace, and making the soul of him who is rightly educated graceful, or of him who [E]is ill-educated ungraceful; and also because he who has received this true education of the inner being will most shrewdly perceive omissions or faults in art and nature, and [402]with a true taste, while he praises and rejoices over and receives into his soul the good, and becomes noble and good, he will justly blame and hate the bad, now in the days of his youth, even before he is able to know the reason why; and when reason comes he will recognise and salute the friend with whom his education has made him long familiar.
Yes, he said, I quite agree with you in thinking that our youth should be trained in music and on the grounds which you mention.
Just as in learning to read, I said, we were satisfied when we knew the letters of the alphabet, which are very few, in all their recurring sizes and combinations; not slighting them [B]as unimportant whether they occupy a space large or small, but everywhere eager to make them out; and not thinking ourselves perfect in the art of reading until we recognise them wherever they are found[38]:
True—
Or, as we recognise the reflection of letters in the water, or in a mirror, only when we know the letters themselves; the same art and study giving us the knowledge of both:
Exactly—
The true musician must know the essential forms of virtue and vice. Even so, as I maintain, neither we nor our guardians, whom [C]we have to educate, can ever become musical until we and they know the essential forms of temperance, courage, liberality, magnificence, and their kindred, as well as the contrary forms, in all their combinations, and can recognise them and their images wherever they are found, not slighting 89 them either in small things or great, but believing them all to be within the sphere of one art and study.
