But, indeed, he replied, I cannot tell you. I only know that there are some three principles of rhythm out of which metrical systems are framed, just as in sounds there are four notes out of which all the harmonies are composed; that is an observation which I have made. But of what sort of lives they are severally the imitations I am unable to say. Then, I said, we must take Damon into our counsels; and he will tell us what rhythms are expressive of meanness, or insolence, or fury, or other unworthiness, and what are to be reserved for the expression of opposite feelings. And I think that I have an indistinct recollection of his mentioning a complex Cretic rhythm; also a dactylic or heroic, and he arranged them in some manner which I do not quite understand, making the rhythms equal in the rise and fall of the foot, long and short alternating; and, unless I am mistaken, he spoke of an iambic as well as of a trochaic rhythm, and assigned to them short and long quantities. Also in some cases he appeared to praise or censure the movement of the foot quite as much as the rhythm; or perhaps a combination of the two; for I am not certain what he meant. These matters, however, as I was saying, had better be referred to Damon himself, for the analysis of the subject would be difficult, you know. Rather so, I should say. But there is no difficulty in seeing that grace or the absence of grace is an effect of good or bad rhythm. None at all. And also that good and bad rhythm naturally assimilate to a good and bad style; and that harmony and discord in like manner follow style; for our principle is that rhythm and harmony are regulated by the words, and not the words by them. Just so, he said, they should follow the words. And will not the words and the character of the style depend on the temper of the soul? Yes. And everything else on the style? Yes. Then beauty of style and harmony and grace and good rhythm depend on simplicity,--I mean the true simplicity of a rightly and nobly ordered mind and character, not that other simplicity which is only an euphemism for folly? Very true, he replied. And if our youth are to do their work in life, must they not make these graces and harmonies their perpetual aim? They must. And surely the art of the painter and every other creative and constructive art are full of them,--weaving, embroidery, architecture, and every kind of manufacture; also nature, animal and vegetable,--in all of them there is grace or the absence of grace. And ugliness and discord and inharmonious motion are nearly allied to ill words and ill nature, as grace and harmony are the twin sisters of goodness and virtue and bear their likeness. That is quite true, he said.
