Let me put the matter, Simmias, he said, in another point of view: Do you imagine that a harmony or any other composition can be in a state other than that of the elements, out of which it is compounded?
Certainly not.
Or do or suffer anything other than they do or suffer?
He agreed.
Then a harmony does not, properly speaking, lead the parts or elements which make up the harmony, but only follows them.
He assented.
For harmony cannot possibly have any motion, or sound, or other quality which is opposed to its parts.
That would be impossible, he replied.
And does not the nature of every harmony depend upon the manner in which the elements are harmonized?
I do not understand you, he said.
